Current Sequoia status
The Sequoia page says OpenCore Legacy Patcher 2.0.0 implemented early support for macOS Sequoia. It also warns that some challenges remain and users should read model-specific issues before installing.
- Newly dropped hardware listed in the docs: MacBookAir8,1 and MacBookAir8,2.
- T2-related problems mean the MacBookAir8,x models cannot be supported at the documented time.
- iPhone Mirroring and Apple Intelligence are non-functional on most patched Macs due to hardware requirements.
Important Sequoia issues
T2 Security chip
MacBookAir8,x has T2 communication panics when booted through OpenCorePkg.
USB 1.1
For Penryn systems, pre-2013 Mac Pros, and Xserve, USB 1.1 support removal affects keyboard, trackpad, IR receivers, and Bluetooth.
Graphics patches
The Sequoia docs state that OCLP includes Legacy Metal and non-Metal patches, but model-specific issues still matter.
MetallibSupportPkg
Some Ivy Bridge, Haswell, and NVIDIA Kepler systems running Sequoia or newer may require this package during root patching.
What about macOS Tahoe?
Tahoe, macOS Tahoe, and macOS 26 are not covered as supported targets in the current documentation used here. Treat them as unconfirmed unless OCLP release notes announce support.
Always check release notes before installing a brand-new macOS version on an unsupported Mac.
