MP 1,1-5,1 OpenCore Legacy Patcher (2.2.0) on Mac Pro 5,1: Issue with Safari and App Store after upgrading on macOS 15.2

[zhaoxitao]

Same problem here, Sequoia 15.3.1 with OCLP 2.2.3, I load no AVX/AVX2 kext in OCLP EFI, the system can boot fine, most 3rd apps can working fine, but App Store crash.

Same thing here.

On discord I found:

Using the mentioned command, I was able to start the app store.
Afterward I changed the setting back with:

launchctl setenv JSC_useJIT true; launchctl setenv __XPC_JSC_useJIT true

I did not notice performance issues while doing this, but it may be completely different with safari and other stuff.

Thanks for your sharing, I used the first comment to successful run App Store, that's great!

I'm not sure why my Sequoia installs do not have these problems. Just upgraded to 15.4.1 - app store and Safari still good. But it suddenly occurred to me - my CPUs are upgraded to X5680s. Perhaps X56xx CPUs are the difference between stability and weirdness.

None of my other upgrades (drives, SSDs, McFiver) are likely to affect app stability. Also, I tried Sequoia before getting the McFiver, so it cannot be the key.

Don't think it has anything to do with the CPU's. Mine are the 5690's and it crashes.

Xeon X5690 has no AVX and no AVX2 capabilities.

Xeon X5690 has no AVX and no AVX2 capabilities.

My reasoning was the OCLP devs may have used X56xx CPUs, and didn't check all Sequoia AVX patches against other CPUs. That would have explained my system's stability vs other peoples' issues.

Don't think it has anything to do with the CPU's. Mine are the 5690's and it crashes.

Ouch. Well, another theory bites the dust.

I have several cMP 4.1 > 5.1 in the office. They all exhibit the safari/ Apps store issue with OCLP & Sequoia < 15.2 , apart from a real 2010 5.1 with original CPUs!

Safari and App store work fine on that computer????

Isn't that a mystery???

the boot disk is a 250 GB SSD is the Apple supplied SSD from my Mac Pro 2013

Can you compare the spoofing level of those machines?

Can you compare the spoofing level of those machines?

Here are my OCLP 2.4.0 spoof settings. 4,1 -> 5,1 without obvious issues. Sequoia 15.5

Target Model: Host Model
SMBIOS Spoof Level: Minimal
SMBIOS Spoof Model: Default
[_] Allow spoofing of native Macs (unchecked)
Serial Spoofing: (both fields blank)

I meant @krakman, as it seems, he has Mac Pros what suffer from AVX problems and one, that not. Interesting data point could be, if those machines with problems run another spoof model. Like the spoofless approach, mimiking running in a virtual machine.

I also had reports from users, who didnt had problems with the App Store on recent Sequoia releases.

Hi Is this the info you wanted?

This is from the working machine.

Hmmmm mystery deepens.....

Using a spare SSD I installed Sequoia 15.5 on another one of my CMP 4.1>5.1.

Safari and App Store work fine!

Unfortunately the Mac Pro that exhibits the problem is in other location, so I won't be able to check it till next week. 🤔

 

[thedogshow]

Just wanted to update those of you still having problems on what I did as a work around, after many weeks of putting this off.

I used the solution already given on page 1 (I think) about the whole AVX/AVX2 thing but being computer illiterate I wasn't exactly sure how to enter the correct coding into Terminal so I got a little help from AI.

So I'll write it out here if anyone wants to try.

First, open terminal and paste this:

launchctl setenv JSC_useJIT false
(hit enter)

Then this

launchctl setenv __XPC_JSC_useJIT false
(hit enter)

Launch App Store and Safari and check. They worked for me. (Finally able to update Logic Pro...lol). The post on page one said that there will be performance issue. I haven't used Safari enough yet to check but I don't really care because I have Firefox installed anyway so I'll just use that if there are any issues. I really just want the app store for updating logic and that's about it.

Anyway, according to the AI, when you shut down, those changes go away so if you want them working you'll have to put those into terminal each time. AI gave me a method to make the changes permanent and it seems to work. They open after a reboot. So here's how to do that.

1. Open Terminal and type:

mkdir -p ~/Library/LaunchAgents
(hit enter)

2. Create the launch agent plist file by running:

nano ~/Library/LaunchAgents/set_jit_disable.plist
(hit enter)

3. Copy and paste this into nano:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>local.set_jit_disable</string>

<key>ProgramArguments</key>
<array>
<string>launchctl</string>
<string>setenv</string>
<string>JSC_useJIT</string>
<string>false</string>
</array>

<key>RunAtLoad</key>
<true/>

</dict>
</plist>

4. Press Ctrl + O then Enter to save, and Ctrl + X to exit nano.

5. Next, create a second plist to set the other variable:

nano ~/Library/LaunchAgents/set_xpc_jit_disable.plist

6. Paste this into nano:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>local.set_xpc_jit_disable</string>

<key>ProgramArguments</key>
<array>
<string>launchctl</string>
<string>setenv</string>
<string>__XPC_JSC_useJIT</string>
<string>false</string>
</array>

<key>RunAtLoad</key>
<true/>

</dict>
</plist>

7. Save and exit as before (Ctrl + O, Enter, Ctrl + X)

8. Load both agents now so they take effect without rebooting (in Terminal)

launchctl load ~/Library/LaunchAgents/set_jit_disable.plist
(hit enter)

launchctl load ~/Library/LaunchAgents/set_xpc_jit_disable.plist
(hit enter)


Hope that helps!
