macOS Tahoe 26 on Unsupported Macs Discussion

So, if you need to use the latest software versions, that’s a good reason to upgrade your system. Computers with Ivy Bridge (third-generation) processors have a problem after upgrading to Sequoia – they don’t support AVX2. Some apps may not work – in my case, it was ACDSee Photo, even the older versions .
It’s also a matter of personal choice as to what each person prioritises.

Most ( if not all) adobe applications now require The CPU instruction AVX 2.0, but if the application has a non AVX2.0 version I found that it works perfectly ( if not better). I did try out adobe premiere pro, and adobe Photoshop (Non Avx2 versions) and both work perfectly on macOS sequoia. Honestly, if the computer BIOS and socket support a haswell CPU (4th gen that natively supports Avx2.0) its a pretty cheap upgrade.

Where can one acquire/download such non-AVX2 versions, for instance, for a Mac Pro 5,1 running Sequoia?

I personally remember getting them from the internet archive ( someone archived them) but I don't know if such person has kept them up. I will try looking for them. But I have switched to davinci resolve for editing simple videos.

FWIW: I have an Adobe “Photography” Plan for $10/mo., which allows me to install Ps on 2 machines.

However, there is no (longer) a direct download link for Adobe installers, even for those of us with subscriptions. The Creative Cloud app won't allow me to even install Ps 2026 on my OpenCore Legacy Patcher 5,1 Sequoia machine. ****heads. I despise them, but it's not worth screwing around with torrents to save $10.

So here's the workaround for others in a similar situation: I install Ps 27.x on my M2 MacBook Pro with Creative Cloud app, then just drag the Photoshop folder out of Applications on that machine across the local network to the Applications folder on the 5,1. et Voilà—Ps runs fine, and Creative Cloud on that machine either ignores it or considers it a legitimate install. Depending on what I'm doing in Ps, the 5,1 is a better machine, if only for the 96GB RAM. The M2 is an insulting 16GB. **** you Tim Cook. (I got the machine pre-owned for practically nothing—otherwise I would never buy a computer with 16GB non-upgradeable memory.)

When Ps upgrades, I just go through the same drill to update the 5,1 installation.

Also, I assume the Ps version I'm installing via Creative Cloud on the M2 (and then cloning to the 5,1) is the “must have AVX2” version...which would suggest that Adobe's prohibition to allowing it on pre-Haswell is arbitrary, or just ********.

Put this on the YT video, but just wanted to say thank you for helping keep my 2017 iMac alive. Hoping to see another release to keep software running on this a while longer, but you OLCP devs don't owe anyone anything and have already done so much 🍻

So, The actual application Doesn't Require AVX2.0? But they say it Needs Avx2? Because if it's true then Adobe be saying some ********.... Not All of Us Can install it on a Supported Device, but I Like your idea, I'll try it when I have access to my Work Laptop and see if it works on my ivy bridge Hack. Thanks!!

The most probable is that since Apple announce Rosetta as non AVX complaint, Adobe are sending you binaries for Intel without AVX support.

Mac Pro 5.1 with Sequoia I have Adobe 2025 installed, but Adobe 2026 requires AVX2

Why would Adobe be "sending binaries for Intel without AVX support” to my M2 MacBook Pro—

If Adobe sent ARM binaries to your M2 MacBook Pro, you wouldn't be capable to run it with your Mac Pro, so the only reasonable explication is that Adobe is sending X86 without AVX2 to you to run with Rosetta.

Ps 27.6 is running natively on the M2 (screenshots). Probably only Adobe could answer this, but why would they be “sending X86 without AVX2 to you to run with Rosetta” if they're actively blocking an installation via Creative Cloud on the 5,1? The Intel prohibition makes no obvious sense.

If Adobe is sending arm64 binaries, how you are running it with your MacPro? Unless is a Universal binary that does not require AVX2, nothing else makes sense.

Correct: they're sending Universal binary to the M2 via Creative Cloud (screenshot). Why would they be sending a UB to me on that machine while prohibiting the installation on the 5,1. I've demonstrated that the UB runs on that Intel machine with no AVX2, so what's the point? This is purely academic now, and who TF can get inside Adobe's opaque logic.

While we're waiting for OCLP 3.0.0, some may want to learn more about the magic behind OCLP. Dortania has provided excellent documentation. Here's a good place to start learning about the patches. The Dortania documentation is an incredible source for those who want to learn more about Macs and hacks.

The OCLP user guide addresses users, not coders. it won't get you anywhere. Using this as a starting point is like looking into your mainbord's manual to figure out how to program it's BIOS – it's uselessl for the task at hand. This is about coding – not "magic"!

Also remember the days of 32- to 64-bit transition of Lightroom where Adobe claimed (correctly) that Lightroom 6 was 64bits, but didn't mention that their installer (or the licensing widget) was still 32bit, so you could "run" it if it was already installed but couldn't re-install it...

tl;dr: (Adobe sucks and) you have to look which *component* has which type of binaries. 🙃

Good morning, sunshine! 🤣. If it doesn't help you, don't read it.

I could not disagree more. The documentation’s target audience spans someone with little to no knowledge of macOS internals to someone who is familiar with macOS internals. The section @deeveedee linked is especially interesting to “coders”.

Adobe Premiere 2022 works ok on Sequoia and my Ivy Bridge computer. No need newer version even for professional use. Thats all )

The Adobe INSTALLER neds AVX2, the software seem to run fine without it.. A recent hack just have the installer's check disabled...

 

[Larsvonhier]

Again, you have said something without Checking ( Didn't we say this before??). That Aside, the Developers have gotten graphics to Work on Tahoe, Educoavs in November Said "2012+ are Very Smooth" That Kicks out Non-metal Which to Be-fair, Are Very old iMacs, macBookpros, and MacBook Air, But They have replaced it with blur ( not liquid glass, that needs the Metal API). Everything I said is the words of EduCovas, Not something I made up. Try to use my idea of doing research Why not? 🙂

In addition to that I´d question what "stable" in this context means. For me, stable (robust) integration of Intel or Nvidia graphics would mean usable, non-crashing operation - even if certain glitches in rendering cannot be avoided or ironed out.

Because the 2022 Version of Adobe Doesn't require AVX2.0 new Versions like 2025 Do.

Exactly! a great example here is non metal! I tried macOS Sequoia on a 2011 MacBookPro (non DGPU model), and it didn't have any glitches But Some software didn't work and some wallpapers didn't work (due to the HD 3000 Inside the sandy bridge CPU Missing Metal) but that's a hardware requirement and the developers can't Bypass that. and it Honestly ran just fine, a little slow? sure But For web use it's simply way better than high Sierra Which support is ending ( honestly better word is already ended But some software still supports it)

OK well good for you. Wha's your point?

 

[ethylmertz]

The Adobe INSTALLER neds AVX2, the software seem to run fine without it.. A recent hack just have the installer's check disabled...

And how does this help with a situation like mine, described above, using a legit Adobe subscription that forces one to use Creative Cloud for installations and updates?

The (Adobe) subscriber has no access to a monolithic installer for any Adobe application. And though the “...recent hack just have (sic) the installer's check disabled...” might facilitate the installation of Ps (for example) on an unsupported machine (like my Sequoia 5,1)—waiting around and wasting time trying to locate that installer for the latest version of Ps (important to many of us) is just that—a monumental waste of time.

That said, if you have a link to a Ps 27.6 installer that “have the installer's check disabled” I would be grateful.

Yeah! will send soon... And it will have all AI functions enablerd for free.. But hey, wait sitted... ;-D
