MP 1,1-5,1 Install Photoshop needs SSE4.2

[madmac66]

First some quick system info:
MacPro 3,1 8core 2.8ghz 32GB RAM GTX760 2GB GPU
MacOS 10.14 Mohave via dosdude patcher

So I’m trying to install my Adobe CC apps on my patched Mohave system. Running into a couple of issues.
1. Adobe only offers current and one generation back of its titles, so I can only legitimately get PS22 (CC21) from the CC manager. This installs just fine but crashes on launch. After a bit of snooping and some luck I found out that PS22 requires SSE4.2 to run, which my MP3,1 doesn’t support. If adobe offered me an option to go back to CC20 I’d be fine but after an hour pleading on a call with the support rep they just won’t budge (absolute ******s, but here take my money, again).

2. Resorting back to CC19 which I am still running in El Cap as I have the offline installers for that generation of CC. However, the installer won’t run as “it cannot get access to a necessary file/folder” or words to that effect, I don’t have the error alert in front of me right now. It made me think f a permissions or ACL problem but I don’t even know where to start looking. I haven’t seen a ‘repair permissions’ option anywhere in years, is that even still a thing? I faintly remember reading that Apple did away with repeating permissions in DiskUtility ages ago.

Really hoping for some ideas to get beyond this. The whole point of installing Mohave was to get access to more current software. Not much point if I’m stuck on the same old jank as in El Cap. If there’s a way to get the CC2020 offline installers or even get this permissions thing sorted I’d be so happy.

Any ideas???

I’m not sure if it will work, or if it is safe but looking at the files within the iso, it looks legit:https://archive.org/details/adobe-2020-mac-os-p-1

DosDude patched Mojave adds SSE42 support (partial but covering most used bits) to MP31 via AAAMouSSE (which can also be injected via OpenCore).

However, if a program or installer explicitly queries the CPU about whether this support exists, it will get a negative answer (AAAMouSSE does not advertise support) and the item will presumably halt. I believe this is what is happening.

It is possible to additionally add SSE42 spoofing via OpenCore to advertise support and return a positive response to queries to get around this issue. There is a limitation however, in that this only applies to queries via the Mac API; which fetches a response from the kernel cache (amended by OpenCore to advertise support).

If the utility skips the Mac API and queries the CPU directly instead however, as I believe Photoshop does (this has been tested IIRC), a negative result will be returned since the CPU does indeed not support SSE42 and does not know about AAAMouSSE.

Hey there Dayo, thanks for confirming that and providing some extra detail. I tried long and hard to get OCLP to work on my machine and gave up after 4days. I won’t waste any more time on it, especially as it sounds like it really won’t help too much with the SSE42 situation

I’ll give it a try, thanks for sharing 👍

I don't know why, but if MacOS installation stucks at a certain point with OCLP, I've noticed that using only DDR2 RAM sticks of max 4GB each (instead of 8GB) usually solves the problem.
