The only thing to find is how to apply these patches.

I investigated the OS to see if existing macOS patches would work - it does seem that they will.

Which explains the problems I’m having above.

This version of macOS introduces a cryptographically signed system volume.

By following instructions in the release notes, I was able to fix it though (I think). Note: There seems to be a bug with kmutil and it does not seem to rebuild kextcache properly. The correct way to ensure kernel collection is recreated is as follows: So we have a new KernelManagement utility - kmutil. Typically we build it via the command:īut this results in the following output:

Rebuilding kernel caches is a very different experience.

All kernel extensions require notarization to execute.

Mounting it, I get another disk in /Volumes which I can indeed mount as writable.

Update #2: Noticed that the root system volume does not show up as "Mounted" in Disk Utility even though its present in /Volumes. It should be possible to patch the system in recovery then, but I have not tried it yet. Update: I was able to mount the system volume as writable only in Recovery - so not all hope is lost. Thunderbolt 2 eGPU users should stay away from this release for now. This will affect scripts such as purge-wrangler and purge-nvda, that will be unable to patch the system. Unable to mount system volume as writable as of macOS Big Sur Beta 1, meaning on-disk patching is not possible.June 27, 2020: Early testing for purge-wrangler support for macOS Big Sur is now available for advanced users. But we all know dosdude and fam are going to roll up on the scene and change the minimum. This means all Thunderbolt 1 Macs are excluded. This release of macOS has eliminated the first-ever Retina Macs from the lineup, with the following minimum requirements: To start off, check out the press release. Will update this post with details that would matter most to eGPU users. so I'll find out soon once I get into testing this new OS when possible. Naturally, Apple did not (at all) dive deep into what's happening to existing kernel extensions, etc.

macOS Big Sur (11.0) is a significant visual overhaul that brings design-language and architecture parity to the Apple ecosystem. At WWDC 2020, Apple finally announced a major advancement to the Mac - the migration to Apple silicon with backwards-compatible support for Intel via Rosetta 2 on newer ARM Macs.
