⚠️ 10.13.6 update to 10.14 will repeatedly panic, UPGRADE kext or UNINSTALL before you update

If you didn't uninstall the kext and performed 10.14 installation like me, you will see a boot loop at the final steps of os x installation. Just shut the mac down, press shift key to enter the safe mode, uninstall the kext file and restart the system, everything will be fine.

I did NVRAM rest. Then could be enter system but skipped system upgrade guide. So I decided reinstall all system.

The upgrade guide did appear with the safe mode way, just FYI.

Thanks for filing this. I'll try to add a feature that addresses this (until 10.14 support arrives).

The latest release improves things. It is still not compatible with Mojave, but it should make it safer to upgrade between system versions.

Hi

Can you help, I am unable to uninstall as per the instructions. I upgraded to Mojave then had boot issues. All attempts to locate the .kext file failed (not in extensions) but kernel kept trying to load it.

I downloaded latest copy and installed that in extensions.

Now I boot

Tried to uninstall as per kextunload commands, but it always fails to find anything to unload.

How can I remove this so its never loaded again ?

Thanks,

Try find /Library /System/Library -iname Thunderbolt3Unblocker.kext. It will write out the path of where the kext is installed, if it is installed. You can then delete these files. Afterwards you can run sudo kextcache -i / and then reboot.

If you cannot find any file, then any boot issues you have are unrelated.

Do not install it again until 10.14 is supported.

Hi

Thanks for your quick reply. Much appreciated. It was def this kext as the kernel panic specifically mentioned it.

Having got it installed, I am able to manually delete the files now and a reboot had no issues. It appears to have just during the upgrade that I had this issue, I assumed it had to be referenced from a file somewhere as it was loading, but not present. Cant explain it, if deleting the file is all that is needed. I know the upgrade do weird things with shadow folders and have a separate folder in-transition (at least they used to) which is made to seem like the real one.

All solved now and thanks for your work and effort on this, as someone who enjoys a little descent graphics power on Mac boo pro, its great.

I have released a new version which should work on macOS Mojave. I also expect that it will work on High Sierra, but I have not tested it.

Before testing, please be sure that you are not running a modified (patched) copy of IOThunderboltFamily.kext.
