macOS 26 may not support 2018 MacBook Pros and 2019 iMacs

Apple's macOS 26 is set to debut on June 9 at Apple's annual Worldwide Developers' Conference, but owners of older MacBook Pros and iMacs won't be able to experience the next-gen operating system.

Specifically, we were told that pre-release versions of macOS 26 are compatible with the following Mac configurations:

  • MacBook Pro 2019 or later
  • MacBook Air M1 or later
  • iMac 2020 or later
  • Mac Pro 2019 or later
  • Mac mini M1 or later
  • Mac Studio — All models
We'll find out for sure with WWDC but good to be prepared. I have an iMac Pro which I'll use until security updates are terminated and then decide whether or not I want to use OCLP. Hopefully Apple will release a large-screen iMac or iMac Pro by then. I will also look at running Windows 11 or 12 and Linux on it.
 
Almost, but not quite, shutting the door on Intel completely.

I suspect this is the “last hurrah” for Intel, though; macOS27 will be all Apple Silicon.

Well, hopefully with OCLP, I can get it onto my iMac 2019. It should still be fast enough if it weren't for the slow fusion drive.

I am not sure if that will be possible. OCLP doesn't currently work with T2 Macs so those with the unsupported T2 Macs like the iMac Pro are out of luck, for now at least. Apple may have removed all support for non T2 Macs from Tahoe. Not impossible that OCLP could add back the missing drivers but there is no guarantee. Video drivers are unlikely to be an issue though give the wide range of video cards supported by the Mac Pro.
