Note that for this release you must reset your boot-args when installing the update by selecting "Boot Options -> Reset boot-args".

This release makes some major changes to the GPU and video codec drivers. If you run into issues, please report it. You can also downgrade to v2.9 if you like.

Changes

• Fixed Polaris22Fixup sometimes not working after a long sleep and then resume (#206)
• Fixed newer Apple AMD drivers crashing on startup (#1) Note that OldRadeonX4000HWLibs.kext (the driver from 10.14.5 Beta) has been removed and the version from your version of macOS is used. This may cause issues (see known issues) and you may wish to stay on v2.9 if you do not want this change.
• Added workaround for 4K 120FPS video stuttering when using Intel Codec (#262). Selecting "AMD Codec" will not have the stuttering issue but will have other issues with Sidecar. Selecting "Intel Codec" will now use AMD drivers for video decoding (encoding will still be Intel QuickSync which is what Sidecar requires). Intel Codec is still the recommended option. You also need to run the new script /Applications/QuickTime Fix.app once (per user) after installation to enable the workaround for QuickTime Player.
• Enable Metal offline compute for Intel IGPU (#213)

Known Issues

• Lower GeekBench score (#286) Unfortunately this is due to Apple's latest AMD drivers registering a lower score than other ones. You can manually install OldRadeonX4000HWLibs.kext with the instructions in #286 but it may stop working in macOS 11.

Installation

Please refer to the guide for a new install. If you are upgrading from an existing installation, just run the installer.
