macOS Tahoe 26 on Unsupported Macs Discussion

[deeveedee]

I realize that my experience will be different from others since each macOS installation will vary depending on the Mac Model, so I'm sharing this in case it helps others or gives any ideas...

I have been updating macOS Tahoe since the first Tahoe pre-release. During that time, I experimented with changes that broke features (like the new Apps menu). I just performed a clean installation of macOS Tahoe 26.2 Beta 3 by doing the following:

• Boot macOS Tahoe 26.2 Beta 3 installer with Open Core EFI
• Erase destination APFS volume
• Start macOS Tahoe install on the destination volume
• On my seriously underpowered laptop, install progress was P-A-I-N-F-U-L-L-Y S-L-O-W. If you're not a masochistic glutton for punishment, this experience may be unbearable.
• Later in the macOS install, uncheck "Reset password using Apple Account"
• Skip the step to login to Apple Account
• When the installer finally arrives at the Tahoe desktop, the desktop was visible with the mouse cursor and without any icons. I let the laptop sit idle for a half hour with no progress, so I reset by pressing <Ctrl> <Command> <Power Button>
• When macOS Tahoe restarted, I logged in and changed the following System Settings for performance:
  • System Settings > Accessibility > Display > Reduce Transparency
  • System Settings > Accessibility > Motion > Reduce Motion
  • System Settings > Wallpaper > Color

After the clean install of macOS Tahoe, the Apps menu is working for me again.

Note that I'm still not testing much until OCLP 3.0.0 post-install patches are available.

Went from 15.7.2 no patches using a standalone installer to go to 26.2 beta 25C5048a using OCLP 3.0 nightly . did install on my mid 2014 MacBook Pro after rebooting after running installer left it for around half an hour then hard powered it off , switch back on left for another half hour hard powered off and rebooted and went to log in screen again only done on a spare partition , all apps open for me. Might have not needed to hard powered off but impatient . Bluetooth works that’s about it lol without being able to patch.

It would be nice, though quite unlikely, for version 3 of oclp to be released before Christmas, a sort of gift for those who want to upgrade to Tahoe. It's much more likely we'll see the release in January or February, and if we have to wait for good compatibility, we'll wait.

No offense, but I have never been a fan of these YouTube videos. I get that the creators need click bait and extended duration to monetize, but I feel like they all went to YouTube school to learn how to take 10 seconds of content and turn it into a 28 minute video. That's 28 minutes that I'm not going to get back. That's just my opinion which I'm sure places me in the minority.

Dortania documentation here still says that the T2 issue does not affect MacBookPro15,2, MacBookPro16,2 and Macmini8,1. Has this been tested in Tahoe? I'd still like to see someone with a real MacMini8,1 attempt to install Tahoe with the required Open Core Booter Patch or boot-arg -no_compat_check (see here for comparison of the booter patch and boot-arg methods).

Great point, @deeveedee ! You're awesome!
These people contribute to polluting the web and often use AI to create very long and completely useless videos.
Unfortunately, many elderly and naive people fall into the trap and remain glued to their smart TVs, watching junk video content, which is not good for society because it indirectly weakens us all.
Thank you for sharing your opinions with us!

Thank you for completing my comment, @ronton3 ! It was indeed a bit incomplete!
I have been influenced by often seeing my peers who, unfortunately, have made YouTube their only source of news, and I have noticed that they easily become immobilised and almost hypnotised while watching long, repetitive videos with no real content.
As a result, they end up not talking to their friends and peers anymore, perhaps going to the pub or playing bowls together, etc., and often lose contact with their families as well.
But I see we've gone off topic, so I'll stop here.
Have a good Sunday.

The 3.0.0 release is definitely not happening this year but maybe, just maybe, macs from 2012-2017 could get root patches as nightly but most likely next year.

This is just my opinion but if people are expecting Tahoe to run well on most unsupported macs, they'll be very disappointed. In my experience, it feels considerably slower than Sequoia.

Don't be too sure about the minority bit. No poll taken, but I think quite a lot of folks here would agree with you
