macOS 15 Sequoia on Unsupported Macs Thread

[vince22]

upgrading my trusty MBP (12,1) macOS 15.4 -> 15.4.1 went kaput/borked, flashing blackscreen only at login screen, booting up safe mode with no avail, weird things happen sometimes, end up resintalling macOS 15.5 beta2 spoofing (15,2) for Universal control to work, no issues so far.

FYI... When preparing a second Sequoia volume for Beta 2 testing, my first attempt to install another Sequoia instance failed, with a boot-loop after the first macOS Installer reboot. It turns out that my SSD was running low on space. I freed-up space in other APFS volumes on the SSD and the installation then proceeded without issues.

EDIT: Scroll bar in Safari is finicky, but not bad for this old hack.

I'm seeing some weird scrolling & zooming behavior in Safari with 15.5 b2 (24F5053f), along with occasional freezes. This is on a supported macmini8,1 (no patches), so it's possibly not an OCLP problem you're having, I dunno.

@rehkram Sequoia 15.5 Beta 2 works perfectly on my "MacMini8,1" hackintosh (which is a bit of a hackinstein, since its SMBIOS is MM8,1 with a Radeon RX 560x). I'm not seeing any Sequoia 15.5 beta 2 issues on my MM8,1 hack. Maybe the issue is with Intel UHD630 iGPU graphics? If a real MM8,1 could get this kind of Metal performance in its tiny form factor, that would be awesome. I'm in the process of switching to the darkside (Windows / Nvidia), but the new Apple Silicon is tempting.
