Problem in Sonoma
I install macOS Sonoma on Thinkpad x280, but I have two problems:
- Cannot find any update in System Preferences
- Cannot boot Windows (11) and/or Ubuntu in OpenCore
- Cannot boot Windows (11) and/or Ubuntu in OpenCore
Because OpenCore changes the ACPI tables before presenting the bootloaders, it will only really work for macOS. If you want to dual boot, use either the laptop's own boot selector, or chainload your bootloaders with something like Grub or rEFInd, and having OpenCore be the end of the chain.
For getting further updates, you need to adjust settings
- Enable
RestrictEventskext Source - Adjust your boot args to have
revpatch=sbvmm
Currently, I am on 14.3 Sonorma and 14.4 Beta 2 released recently.
