1. What is going on hither ? – #Varsectomy
The purpose of this article is to gather all known information and information around the current issues some Gorging and Not SIP protected Macs are experiencing. The issue first started on Mon 9/23/xix.
Late Yesterday some #MacAdmins started to written report that a few of their systems would non boot properly. They would have the following bug.
- 1. After rebooting the afflicted organisation it would Kernel Panic. The organisation volition reboot just to KP once more
- 2. User Logs out and the arrangement shows the Setup Banana.
- 3. The Arrangement Kernel Panics into a boot Loop.
Avid users were some of the first to report the issue. AVID.com says
Sometimes Gorging Media Creators use third Party Graphics cards connected to their Mac Pro. When the consequence hit yesterday, it was thought that AVID was the chief cause of the problems since all the users experiencing the outcome had AVID software.
Only later after a MacAdmins deep dive investigation was information technology found that Gorging was Not the crusade of the problem. Information technology was Google Chrome Keystone Updater!
Join the #Varsectomy aqueduct in MacAdmins Chat for the latest info!
2. Which macOS Versions are affected ?
MacOS x.9 – 10.fourteen Mojave
Notation: macOS 10.9 & 10.ten and then not accept SIP. Arrangement Integrity Protection was introduced in macOS 10.11 El Capitan.
3. Specific Mac Hardware ?
At first it was start reported that the 2013 Mac Pro was affected, this is not true.
Now it seems the issue affects all Macs that have SIP (System Integrity Protection) Disabled or turned OFF
Cheque if SIP is enabled past running csrutil condition
-
Organisation Integrity Protection condition: enabled. -
System Integrity Protection status: disabled
four. SouthIP – System Integrity Protection
All Reports then far look to be from Macs that take SIP Disabled!
Please exercise not disable SIP, information technology was created to protect macOS from this very upshot.
5. AVID or Google Chrome Keystone Update causing this issue ?
At first the consequence seemed to be caused by Gorging Media Composer. Afterwards further investigation it was found that AVID was not the problem! Some AVID users may demand to DISABLE SIP for tertiary political party Video Carte back up.
After investigation from some of the top minds in the MacAmins Slack Chat #varsectomy channel it was institute that the Google Keystone Updater was at the centre of the outcome.
The Google Chrome Keystone updater lives here (if set to only update for the user who installed Chrome) – ~/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/
If set up to install for ALL users. (This also prompts for admin access for install) Thanks Jeff Johnson /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/
You can run the Google Chrome Keystone Updater Manually to kick off an update bank check. (Note: Google has disabled the updater for now!) see bugs.chromium.org/p/chromium/bug/particular?id=1007358
~/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resource/GoogleSoftwareUpdateAgent.app/Contents/MacOS/GoogleSoftwareUpdateAgent -runmode oneshot
Give thanks you eholtam for the VM investigation and Screenshots!
After kicking off the update you can see the problem beneath.
Found and deleted symlink at path /var
half-dozen. How do I check my /var symlink?
Cheque to see if your /var symlink was modified by running the following command.
ls -ldO /var
You should get one of the following outputs. The kickoff one beneath means that your /var volder is SIP protected (discover the restricted flag) and the proper sym link /var -> private/var
[electronic mail protected] 1 root wheel restricted,hidden eleven Apr one 2018 /var -> private/var
The adjacent one ways that your symlink is broken and the folder is NOT SIP Protected.
drwxr-xr-10 5 503 cycle - 170 Sep 24 xiv:37 /var
If you find /var in this condition you lot are afflicted! If you LOGOUT, SHUTDOWN OR RESTART your Mac volition NOT Kick! You lot will need to boot into recovery, repair the /var symlink and reset the restricted flags. Gear up beneath.

14 total Zoom Vulnerably / Exploit variants and a RCE Remote Code Execution establish!
Just when you had enough of the showtime Zoom Vulnerably, Apple released MRTConfigData 1.46 (now i.47!) to bargain with xiv total variants and a Remote Lawmaking Execution (RCE) . I created this Index of MRT Links & Info to assist yous get through the confusion.
Jonathan Leitschuh reported the first vulnerably in Zoom. I wrote an article talking nigh this and how to remediate the RCE and Conferencing Video Bug here.
UPDATED: 07/18/nineteen – MRTConfigData 1.47 released and iii more Zoom variants! Brings the total to 14.

1. List zoom opener variants and MRT Versions
How do we even know which variants are included in MRTConfigData v1.45 and v1.46? (Now i.47!) The only fashion to find out is to dig into the MRT Binary Code. I talk almost how I constitute the new variants a little more in section seven below.
Nosotros at present have 14 new Zoom Opener variants to worry virtually. Each one is a subconscious folder listed in your user binder!
MRT Versions
- 1. MRTConfigData v1.45 – 7/ten/19
- ii. MRTConfigData v1.46 – 7/16/xix
- 3. MRTCOnfigData v1.47 -7/18/nineteen
Zoom Variants
- 1.
/.zoomus– ane.45 - 2.
/.ringcentralopener– i.46 - iii.
/.telusmeetingsopener– 1.46 - iv.
/.btcloudphonemeetingsopener– 1.46 - 5.
/.officesuitehdmeetingopener– ane.46 - half dozen.
/.attvideomeetingsopener– 1.46 - vii.
/.bizconfopener– 1.46 - eight.
/.huihuiopener– 1.46 - 9.
/.umeetingopener– 1.46 - 10.
/.zhumuopener– 1.46 - 11.
/.zoomcnopener– 1.46 - 12.
/.earthlinkmeetingroomopener– 1.47 - thirteen.
/.videoconferenciatelmexopener– 1.47 - fourteen.
/.accessionmeetingopener– 1.47
2. MRTConfigData Compatible OS versions.
You tin can run the MRTConfigData update on the following macOS versions.
- Mojave x.14
- Loftier Sierra ten.13
- Sierra 10.12
- El Capitan 10.11 (Note: You tin merely apply
softwareupdate -ia --backgroundequally the--include-config-dataoption was new in Sierra 10.12 )
3. Software Update & MRT Commands
Let's get right to information technology, here are the commands once again if you want to remediate right now!
- i. Bank check for config data updates:
/usr/sbin/softwareupdate -50 --include-config-data - 2. Manual Install of MRT v1.47:
/usr/sbin/softwareupdate -i MRTConfigData_10_14-1.47 --include-config-information - 3. Verify Version of MRT:
/usr/bin/defaults read /System/Library/CoreServices/MRT.app/Contents/Info.plist CFBundleShortVersionString - iv. Force Run MRT.app in Agent manner:
/System/Library/CoreServices/MRT.app/Contents/MacOS/MRT -a
If MRT finds Zoom the manual browse will look like this.
iv. Malware Removal Tool Documentation
Apple has non documented how the MRT Browse works. The MRT Tool is chosen out with simply a few lines in the macOS Security Overview for Information technology.
Apple refers to MRT updates as "Silent or Quiet Update" when referenced in the media. The MRT Binary doesn't have a MAN page or a -help section. Targeted malware variants are not documented. Sounds like a chore for #MacAdmins!!!
5. Caveats of installing MRTConfigData and how the MRT scan works differently in 10.14 vs x.13
Yous need to know near a few caveats with this process. I have tested the installation and browse multiple times and found differences in each Os! Let'south start with Mojave 10.14 then move to High Sierra 10.xiii.
MRT in Mojave 10.xiv.5
- When y'all manually install the
MRTConfigDataupdate the MRT.app will automatically run a MRT Scan! - You only have to worry about other users who may accept installed any of the opener variants as the MRT Scan only runs for the logged in user only.
- A restart and Logout/Login will kick off a manual MRT Scan.
- You lot can run a script that Rich wrote that will remove zoom from all logged in users.
- github.com/rtrouton/rtrouton_scripts/tree/chief/rtrouton_scripts/fix_zoom_vulnerability
MRT in Loftier Sierra ten.xiii.half-dozen
- A reboot will kick of a MRT Browse
- A logout and login will kick off an MRT Scan
- When you manually install the
MRTConfigDataupdate the MRT Scan will NOT run automatically!!! - You will need to run the MRT.app amanuensis scan manually to remove whatever zoom variants.
TLDR: Installing MRTConfigData in 10.xiv automatically kicks off the MRT.app scan, while in ten.13 the MRT scan does Non run automatically.
H/T to @howardnoakley and @alvarnell for pointing out that after installing MRTConfigData the MRT Scan kicks off automatically. I did not know it at the time merely they were testing in 10.xiv. All my testing was on ten.13, so thats why I was getting dissimilar results!
6. Other ways to install MRT updates
If yous are on Mojave 10.14.v you will automatically go the MRTConfigData update as long as you have the following SoftwareUpdate Settings set to ON.
Every bit long every bit you have these settings set to ON your Mac should automatically check in for new updates and install them every 24 hours.
For the com.appleSoftwareUpdate.plist file y'all need the following settings fix to ON.
/Library/Preferences/com.appleSoftwareUpdate.plist
-
AutomaticCheckEnabled = 1 -
AutomaticDownload = 1 -
ConfigDataInstall = i -
CriticalUpdateInstall = 1
If y'all desire to install all background updates at present without waiting you can issue the post-obit command.
sudo softwareupdate --groundwork --include-config – Merely background updates
or
sudo softwareupdate -ia --include-config-information – Groundwork updates AND Os level Updates
NOTE! The -ia option will install ALL available software updates including Combo, Safari and Security Updates.
The above commands will merely install Xprotect updates if you take all the automatic software update settings set to ON.
seven . Excavation into the MRT Binary
Apple does not list the targeted malware variants anywhere, then the merely fashion to observe them is to dig into the MRT Binary Code. You cant but open the code inside MRT equally it has thousands of lines of code. You have to starting time compare the current version to the old one. This volition give y'all the showtime clues, equally each piece of malware is given a lawmaking. In this case it was MACOS.354c063.
At present that nosotros have the Malware Family ID we can then search the MRT Binary using a disassembler application. A disassembler like Hopper is used to view the actual code of the new MRT binary.
8. More questions, Issues and Errors
We yet have questions nigh how the MRT works particularly the MRT -d or daemon mode. I accept fifty-fifty reached out to Apple for an respond on this.
Howard Oakley wrote a great commodity looking into this.
eclecticlight.co/2019/07/13/what-happened-when-mrt-was-updated-and-what-mrt-does/
This is the best information we have then far.
Problems and Errors
Trying to run a manual update and scan tin can cause some bug in sure situations.
- i. Running
/usr/sbin/softwareupdate -i MRTConfigData_10_14-1.47 --include-config-datashows
Upshot of command:
MRTConfigData_10_14-one.46: No such update
No updates are bachelor.
If this happens run /usr/sbin/softwareupdate -l --include-config-data first.
- two. Running the MRT Browse from a script shows
MRT Scan failedToReceiveProfileList
Yous will need to run MRT in 10.fourteen as the logged in user.

Let'due south say you want to download the full macOS installer.app from Apple and then y'all tin deploy in-place upgrades or build a USB Installer. Let's first check Support.Apple.com/Downloads.
-
Searching for macOS x.14 Mojave -
Searching for macOS 10.xiii High Sierra
Hmmm… Searching for Mojave and High Sierra installers only prove philharmonic and security updates.
two. Loftier Sierra Mac App Store
No big bargain, permit's get to the Loftier Sierra App Store and search for Mojave and Loftier Sierra installers.
-
I institute Mojave -
High Sierra not plant 404
Ok, well we are getting a fiddling closer it seems. Searching for macOS Mojave comes up, yet High Sierra is nowhere to be institute.
iii. What happens if you lot have an one-time version of installer.app on your system and desire the latest version?
You now see Mojave is at that place in the Mac App Store, but instead of
Later clicking Open I am presented with this message above. As y'all can run into the App Store first searched my system and found that I already have macOS Mojave installer.app. Notice that information technology searches all locations, not only the Applications folder where the installer app normally is stored. It found the macOS Mojave Installer.app in a folder chosen exam.
Great, we are ready to go right? Not really because I have no inkling what version this is. Looking at the creation date gives us a pretty good inkling. MacOS Mojave was released on September
4. How do I check the macOS version number of Install macOS installer.app?
We take multiple ways of checking the version number and build number. The easiest fashion is to simply look at the version number info from Go Info .
After checking the version number, I now know the macOS version is ten.14.0. We tin observe the build number inside the actual installer.app but knowing the version number is usually good enough unless y'all need a specific hardware build.
five. Downloading the latest version after finding an old version.
I accept macOS Mojave Installer.app on my organisation but it's outdated. I need the latest version. Nosotros now need to go the app store to show the Download push instead of Open . Simply shut the App Store, delete the old version of macOS Installer then re-open.
I deleted the installer.app but the App Store still thinks that I accept the installer. The button SHOULD switch to Download but didn't. If this happens again just restart your Mac.
Perfect, later on restarting the Mac App Store can't find any version of the Mojave installer on your Mac then it at present shows you the download button.
6. The Mac you are using has to be compatible with the macOS version you are trying to download.
We could not complete your purchase. This version of macOS x.14 cannot be installed on this computer.
I Even so can't download Mojave because the Mac I'm trying to download it on is non compatible. All I want to practice is download macOS Mojave! I do understand why Apple did this, they don't desire a user to think they could install Mojave on a system that tin't run it. Apple should take this one step further and not show it as bachelor in the App Store. Or have the button say Not Supported .
7. If Mojave is not uniform with my organization, how practice I download High Sierra 10.13?
How do I download macOS Loftier Serra 10.13? If searching High Sierra in the App Store comes up empty how can I download it? You have to visit the Apple Upgrading to High Sierra Support Page for the straight App Store link.
We are back in the x.xiii App Store, permit's try to download once again.
Subsequently clicking Download nosotros finally become some action!
I have a pretty fast connection only not five.3 gigabytes in 3 minutes fast. The download just finished let's see what the bargain is.
eight. The dreaded 22mb"Stub" installer.
This is what'southward known as the macOS "Stub" Installer. This is not the 5gb full installer we are looking for information technology'due south only 22mb! All this file will do is start the installation but to download the full 5gb before starting time the install. You cant boot to this file or create a USB Installer from this pkg.
While the ten.thirteen App Store does not allow you to download the full High Sierra installer, information technology will allow y'all to download the total version of Mojave.
nine. The Mac App Store was redesigned for Mojave 10.14!
The App Shop was totally redesigned for x.14 Mojave. The look is pretty unlike from 10.13's App Shop. This is what the Mojave section looks like in the new App Store.
The new design aligns the Mac App Store with the iOS App Store. The outset hint is that the
-
The Become push button starts the process. -
Sure y'all want to download a 6gb file?
-
Demand Admin creds to start the download -
Profit
We are off to the races now! The first thing you will notice is that instead of downloading macOS Mojave Installer inside the App Shop it opens Software Update. Software Update will search for the Installer and ask if you lot are certain you want to download the 6gb Mojave Installer. Afterwards clicking download you volition get a new prompt for admin credentials to start the download (not to really install yet). Later
one0. Tin can I download Loftier Sierra in the new Mojave App Store?
Expert news, the Full Loftier Sierra installer volition now download from the new App Store.
11. The new Mac App Shop has solved the dreaded 22mb "Stub" installer problem.
The "Stub" download trouble can be reproduced using 10.13 App Store. Even so I can't seem to reproduce this on x.14. I have tried multiple machines. The "Stub" installer problem seems to be gone as long as you are using ten.14'south App Store.
12. Mac App Shop Errors
If y'all get i of the following errors, follow look at the next section below.
- The requested version of macOS is not available
- This version cannot be installed on this computer
xiii. Review of which macOS versions y'all tin download on Mojave & Loftier Sierra depending on your Mac Version.
Afterwards all this testing, we know what tin be download from the App Store. We also found out what tin't download. Afterwards performing multiple tests with each OS you can download any newer version, the current version merely only 1 OS behind. You will go a mixture of "The requested version of macOS is not available" or "This version cannot exist installed on this calculator"

In this commodity, I will talk a petty bit about the current state of Apple'due south Documentation. After that, I will testify you iii Undocumented 10.fourteen Mojave fixes that can help yous as a MacAdmin.
Documentation, Documentation, and Documentation. Say it 3 times fast! MacAdmins just desire Apple tree to provide proper documentation for features, controls and security settings and Enterprise Fixes. In some cases, Apple provides excellent documentation. An example of this would be the T2 Security Chip Security Overview released in Oct of concluding year. In other cases when it comes to binaries like sysadminctl not so much.
The all-time that I could find was a certificate called "If you see authentication server errors when turning FileVault on in macOS High Sierra". This article does not even mention SecureToken. Y'all can get a few nuggets of information by checking the sysadminctl binary options only sysadminctl doesn't have a man page. I even performed a search on developer.apple.com/documentation as you can come across in the picture higher up. I will be writing almost sysadminctl side by side week. Mayhap I can create a MacAdmins version of a sysadmincatl man page! Even so when I search for "SmartCard" three documents show up. SmartCard support is a small slice in the overall macOS pie, yet has multiple documents! Side Notation: Shout out to all my peeps in the MacAdmins.slack.com #SmartCard aqueduct (about 5 people) 🙂
Documentation is getting meliorate.
If you have been keeping track, Apple documentation is getting better. If you await at the "What's new in the updates for macOS Mojave" folio you lot volition come across a big number of fixes. Eagle eye MacAdmins will be kickoff to spot " Enterprise Content" , this is the stuff MacAdmins are interested in.
10.14.2
10.14.3
10.fourteen.4
Check out that start ane under 10.14.4! As noted in my previous article, I fought to get that one fixed since ten.14.0. It's really great to run into that ready get mentioned in the Enterprise Content area.
What do yous mean undocumented fixes ?
Apple is constantly fixing things backside the scenes. MacAdmins continue to file radars, phone call Apple Care, test beta releases, submit feedback and submit Apple Enterprise Support tickets. Defects and bugs ARE getting fixed but are not listed in Apple'due south Enterprise Content listing. I am not totally sure why certain fixes do not make the list.
Perhaps Apple wants to keep the list curt while focusing on the major fixes. I wish Apple would list more of them, even if they posted them in an enterprise only area. An case of this would be AppleSeed for Information technology. If you are office of an Enterprise or Schoolhouse you tin exist selected to join the plan. I highly recommend joining if you are non a member already. Y'all can read the FAQ nigh joining eligibility here. Inside you will find links to macOS beta downloads and beta documentation. Each beta release (Sometimes upward to vi releases per combo update) will show what has been stock-still between updates. This is great information for any MacAdmin to have so you can stay on top of what's going on.
3 Apple Enterprise fixes included in 10.14.0 – 10.14.4
ane. macOS x.14 Mojave can at present provide FV2 Authenticated Restarts for Combo and startOSinstalls.
In 10.14 macOS Updates and Upgrades are at present able to perform Authorized Restarts. This feature was not an option in previous releases. This is a pretty big deal, especially for #MacEDU and Enterprise customers who have computer labs.
Previously if you installed a macOS update and the system was FV2 encrypted information technology would restart but STOP at the FV2 unlock screen. If you performed this update remotely you would lose control of the machine. Things become worse at FV2 login window because firmware volition close the Mac down after 5 minutes of inactivity. The aforementioned problem volition happen when you first a macOS Upgrade. Y'all will be disappointed after returning from lunch thinking the update is complete only to find the Mac turned OFF. You then ability the Mac dorsum on merely to find the installer has just started with 40 minutes remaining. With 10.14 if you kick off a combo update or macOS upgrade the installer will perform an Authorized Restart and you will never get stuck at the FV2 prompt once more!
For startosinstall you but take to store the mojave.app in a folder like /Users/Shared. And then boot information technology off with this command – sudo /Users/Shared/Install\ macOS\ Mojave.app/Contents/Resource/startosinstall –nointeraction The –nointeraction option will prevent license agreement message.
ii. Installing software updates using the -R restart option at the login window now properly restarts the Mac to the installer. (10.xiv.4)
When Apple released the T2 security chip they also added additional options to the softwareudpate binary and then information technology could handle BridgeOS updates. Installing a combo update on a T2 Mac is at present a multi-step process. Using softareupdate step one remains unchanged, it volition download the combo update from Apple which in turn stores in /Library/Updates. For step two, the Mac reaches out to Apple'due south personalization service (gs.apple tree.com) verify the BridgeOS and combo update. When the verification is complete y'all will have a new folder in /Library/Updates called PersonalizedManifest.
Y'all are automate the entire process by using sudo softwareupdate -iaR . Options -i will install the update, -a will download all updates and -R volition perform an automated restart. The process works only fine if y'all are the logged in user. If the system needs to update the BridgeOS the Mac volition shutdown and then will ability back on with the T2 Chip to install the BridgeOS update. If the system does not require a BrigeOS update the system volition restart to the update installer. The problem comes in if you attempt to automate the install from the login window using the softwareupate -R or –restart choice. Softwareudpate will run run through the process listed out to a higher place only to end at the very end and be unable to restart.
One time all your Macs are updated to 10.14.4, you lot can at present utilise the -R restart for all situations. Softwareupdate can now restart the Mac if it'due south at loginwindow.
iii. 10.14 FV2 Authorized restarts can employ the PRK (Personal Recovery Key) again.
When 10.thirteen arrived you could no longer perform FV2 Authenticated restarts using the PRK (Personal Recovery Key). This feature was simply flat out broken. This previously worked in x.12 Sierra and below. NOTE: You could all the same perform an Authorized restart with your FV2 name and password. An example of a PRK Authorized restart would be if yous are a JAMF Pro customer and had a policy that installed a package but it also required a restart. You could select the option "Perform Authenticated Restart" Jamf would then send a fdesetup authrestart using the PRK. The packet would install and so the system would perform an FV2 authorized reboot so the user did not take to enter in the password at the FV2 unlock screen.
ten.12, 10.eleven & x.10 – Works!
sudo fdesetup authrestart = Enter a countersign for '/', or the recovery central:
x.13 – Doesn't piece of work
sudo fdesetup authrestart = Enter the user name: ( hit the enter central to toggle Recovery Fundamental Entry) = Error: Missing user proper name. Error: Unable to restart (fault = -54).
10.14 – Works once again!
sudo fdesetup authrestart = Enter the Username: (once more hit the enter key to toggle Recovery Key Entry) Enter the current recovery key:
I hope that at least one of the fixes I mentioned in this article helps you. In the future I would love to see more than documented Enterprise fixes listed in the combo update patch notes. Until then though, I will continue to certificate said fixes and let yous know about them when I tin can.
If you accept whatsoever questions or comments, please feel free to reach out!
