macOS Tahoe 26 on Unsupported Macs Discussion

[Payne Mononymous Bachman]

No. Future releases will not contain any Intel code at all and will not be able to directly boot at all on Intel Macs. It is (and will remain so) possible to boot arm64 macOS on an Intel Mac using emulation on an X86 host OS.

The next conversation we'll be having is running a future macOS (probably 28) on unsupported Apple Silicon hardware, once the M1 series of chips are dropped. macOS 27 will certainly support all generations of Apple Silicon, but macOS 28 and beyond could drop support for M1 or even M2. I could see them dropping M1 and M2 simultaneously because they are extremely similar (not much more than clock speed for differences). M3 is the first major architecture change for the Apple Silicon chips (moving to armv9, significant GPU changes, significant NPU changes). It would be very likely that M1 can support anything M2 can support, but neither supporting things the M3 can support. This is not unlike the Intel transition, where the initial Intel Core and Core 2 chips were dropped aggressively in favor of the vastly improved core-i series.

I do not see the M2 being dropped anytime soon. It is in the MacBook air which is from 2022. Dropping it with macOS 28 would only give it 4 years of support. M1 may get dropped but I feel that macOS 28 would still support it. What I will be interested to see is if the M1 does get dropped will OCLP start back up again and focus on supporting M1 machines.

Tahoe is installable on my mac mini 2012 (external SSD), it boots on configuration window but once i arrive on privacy window it stays few minutes black then it restarts.
Inpossible to install it on mini 2018.

2018 Mac mini has a T2 coprocessor. OCLP has not found a way to support that yet.

I believe OCLP built on work done by the Hackingtosh community to support non-Apple hardware. It seems very unlikely that anyone will ever create an ARM based Hackingtosh.

Yes, they update to OCPL to include and IMAC 19.1, I tried to test, create without error the EFI partition, but after the reboot in EFI the imac remains blocked on a black screen, no longer installs Macos Tahoe
