macOS 15 Sequoia on Unsupported Macs Thread

[MacinMan]

So, after doing some testing today, Gog fixed galaxy so it still runs under Monterey, and what made me think I had to upgrade to continue to use it, turned out to be a bug. With that said, is there anyone who uses open Core to run Monterey on an older unsupported Mac? It's natively supported for me, but I was asking if anyone here that may be using it with OCLP, or natively how at risk is the system at this point in terms of security? I've been using Sequoia a little over a week now, and the only advantage I've seen is upgrading to the latest versions of the Apple apps, and a few of my third party ones as well. In terms of anything special coming from that, I haven't seen anything I already had under Monterey. Currently I have Monterey installs on an APFS volume as a secondary install but now I'm wondering how safe I'd be just sticking to it as long as possible .

@OKonnel I opened an image in Preview under 15.4 on my 17, 1 iMac and here are the screenshots of the two windows.
According to google, finding the histogram is under adjust color, so hopefully you can see if it's there, or not based on the pictures.

Hey all, I'm a bit unclear regarding feature unlock in the Open core app. By default it's disabled, however on my iMac 17,1 under 15.4, Continuity camera was working, but according to Dortania, Feature Unlock needs to be enabled for those features to work. Since my iMac is Metal and AVX2 compatible does the feature unlock setting not matter, and is it for older non metal macs only? A bit of clarity would help thanks.

Theoretically, yes. Really strange!

Keyboard/Mouse share also works with feature unlock disabled on MBP11,2.
My scenario: MacMini M4 Pro sharing with MBP 11,2.

I can't remember when I updated to Sonoma.

I'm now going to venture in Sequoia.

Do I use the DVI monitor input to ensure seeing the progress?

Running the RX580, and currently on Sonoma. THANKS

FeatureUnlock is not needed for Kaby Lake+ CPUs.

Very smooth upgrade from Sequoia 15.4 -> 15.5 Beta (24F5042g) on my HackBookPro6,2 (2010 non-metal Nvidia Tesla). Applying post-install patches with OCLP 2.3.2. Very impressed by how well this old hack continues to perform. OCLP Devs, thank you for preserving the fun in tinkering with old hardware like this! Still hoping for another year of Intel support so that the fun doesn't end.

MBP5,2: Smooth re-installation of 15.4 from USB installer, using latest OCLP 2.4.0n for EFI and root patching.
(Something had gone wrong with the first installation as written earlier - needed safe boot then had no graphics acceleration. Now all fine i.e. graphics, USB1 (internal keyboard+trackpad), WLAN.)
Didn't try yet migration of user data by migration assistant or CCC.

Machine is now 15.5 years old, release numbers seem to match its age. - Thank you developers!

Thanks, I have a Skylake here, the 2017 iMac that came out the year I got this one is the Kaby Lake. It was one of those times where no one knew if Apple was going to refresh the iMac or not, so I got what I needed at the time, and it came out in just enough time that I couldn't exchange what I got. At this point, though it wouldn't really matter, I'd only have the rest of this year with native Ventura support before Apple cuts it off.

Also, after looking at that page, my late 2015 iMac supports Sidecar natively, it would need open core for airplay even under Monterey, and then newer features of course.

macOS 15.5b2 installed atop 15.5b1 OTA, OCLP v.2.3.2, runs better than expected.
👏

similarly for MBP11,1: updated OTA from 15.5b1 to b2 on external SSD, using OCLP 2.3.2, good result.

One thing I have just noticed with 15.5b2 is that preview which was quick after a beachball opening, is now instant from the start, no more bb's. I haven't found any problems.

Thanks again Dev's.

Have you been able to download the update? It doesn't appear to be available in OCLP yet?

I installed OTA, simple quick and good results, the patcher said that the KDK for 15.4 was closest, so no message from OCLP to update during the OTA download.
