macOS 15 Sequoia on Unsupported Macs Thread

[rafark]

Hi, I‘m new in the board. Will OCPL Support MacBook Air 2029 sometimes? Are there any infos from the devs?

Nobody knows 😂

I'll consider that, and I have also considered creating a second appleID too so i have my main one for my stable install and one for testing.

EDIT: I wanted to add, I never signed into my AppleID, or iCloud when setting up Sequoia on a separate APFS volume. However, when booting back into Monterey, I got the "this mac cannot connect to icloud" message and required my password, and a fresh verification code. I understand this when I actually sign into a second install on the same Mac, but what causes when I don't sign in? and simply reboot into the other install? It makes no sense. Does anyone have any way to explain this, and how to stop it?

You didn't sign but the Mac's serial number is identified with another version of macOS. That maybe causing the issues.
I had the same problem with Big Sur and Monterey a while back. I was testing Monterey to see if I would do the transition with the no-compat-check and never signed on Monterey either.

@Neon Ball I'm not making this post to pick a fight, but simply present evidence that there is information that seems to be not fully correct. I wasn't going to respond unless I could upfront prove I get 4K video from YouTube on Safari with this iMac. Here is a screenshot showing this iMac does support above 1080p for YouTube on Safari. The information you provided may be Apple's requirements for later versions of macOS / Safari, or it could be an OCLP limitation. However, as I originally mentioned, I primarily use Firefox or Chrome, so Safari is a moot point for me. However, I am providing feedback that my original hunch was still correct, and I am Able to get safari to play 4k YouTube Videos natively.

Did you check what codec was being used? For example on my 2015 15" MacBook Pro, Safari plays YouTube at 1080p max regardless of OS (just tested on native Monterey) and it is using AVC/h264. Meanwhile on my Kaby Lake Hackintosh, 4k is available because it has hardware accelerated support for VP9. I can get VP9 on the 2015 15" by using a 3rd party browser.

Try this. Go to System Settings > Control Center > .... first item in list is WiFi, should be set to "Show Wi-Fi in menu bar"

There is no icon on Wi-Fi menu....

🎉 Tech Magic Alert! 🎉

Guess who just turned their vintage Mac Mini 2012 (MacMini6,2) into a macOS Sequoia 15.2 powerhouse? Yep, this guy! 🙌 Big shoutout to the awesome OpenCore team for making it possible. 🚀

My old Mac is now strutting its stuff like it’s 2012 all over again. Who says you can't teach an old Mac new tricks?

Long live the Mac Mini! 🍏✨

@Neon Ball Hi again, Just checked with stats for nerds. Looks like it's doing 4K VP9. According to the display.
See attached screenshot, for the details. This is Monterey 12.7.6 and safari 17.6 running natively on this late 2015 iMac. OCLP isn't even installed right now to eliminate as many factors of change as possible so it's running in a configuration direct from Apple without modifications by me (the user.)

Edit: adding a screenshot from firefox of the same video and stats for nerds.
