Anyone having problems with Pixelmator Pro and OpenCore Monterey 12.3.1 on a Mac Pro 5,1? Running Pixelmator Pro tends to end with a power cut / system crash / unable to power on until 20 second SMC reset!
I don’t have this problem (on a MacPro 4,1 flashed to 5,1) with Martin‘s 0.7.9 package and Monterey 12.3.1
 
Hi!

I got a question:

I change my MVMe startup disk, in finder, from BigSure to Monterey. But in the OC start up option menu the BigSure name still remains. Can I change this, some how? My startup disk is crypted with FileVault.

Best regards

/Doc
 
Thanks for the help everyone. Can someone point me to the article/page in which the instructions on how to get bluetooth enabled Mac 5,1 after installing 12.3.1? Appreciate your help.

I am not sure on the hardware specs of your cMP and specifically the BT/wifi card you currently have installed. Nevertheless, the following post and subsequent 3-4 post replies might offer some solutions/clarifications to your problem:

I've solved the problem! The crash was caused by the RX380 card drawing too much power from the single 6 pin mother board power connection to 8 pin graphics card connection! Replacing the single power connector with a dual 6 pin to single 8 pin connector and using BOTH mother board power outlets has solved the problem!

Hello everyone.
I bought a couple of XFX RX580 8 GB GPU's for some of my Mac Pro systems and I found a weird bug when booting those GPU's with OC.
Turns out this specific GPU model from XFX gives a green background color (instead of the black one) and some very weird rainbowy icons and names for the bootable partitions (instead of the regular colors and white text). Colors come back to normal as soon as you boot any partition and the OS loads the Log In Screen. Everything is working pretty damn fine, I even have a WIN10 partition with Warzone and it plays just fine, it's just the bootloader's colors that weird me out.
I tried both GPU's and both did the same on my mac pro's, tried on a PC and never got any green screens on boot menus, BIOS menus, etc. So I narrowed it down to the config file for OC's bootloader.
I've tried to get more familiar with the config file but I couldn't find anything regarding the color palette or color mode for the bootloader, at least not that I could understand.
Is there such an option in the config file for the GPU's color scheme on OC?

Here are the specs for the 5.1 that's keeping that GPU:
- Mac Pro 5.1
- 2x X5690
- 32 GB RAM
- XFX RX580 GTS XXX Edition 8GB GPU.
- Mac OS Catalina 10.15.7 on NVMe.
- OC 0.7.8 (Martin's package) on SATA HDD.

Thanks in advance!
Is there anyone that can help me out?
Thanks in advance!
 
Im not getting HDMI audio on one of my dual core mac pro 5.1 builds which has an RX 590 Sapphire Nitro+.
Some times when I boot the machine I can use it and it works out fine, some other times it wont even appear as a selectable device.
Is there anything I can do to make the system deliver HDMI audio everytime?
Thanks in advance

I did read that post as well, but almost at the end of the thread you did mention you dont need to use that method for catalina, and those kexts are already on your package.
So what am I missing? How do I get back my hdmi audio then?
 
I'm on cMP5,1(mid 2012) with legacy WiFi/BT, AMD Radeon RX580, and Monterey 12.2 using OC 0.8.0. I did the config.plust changes to VMM flag ON/UpdateSMBIOS OFF but I'm having trouble with Software Update not showing the upgrades for the macOS from 12.2.

In November 2021, using 0.7.5 I'd upgraded from 11.6.1 to 12.0.1 successfully and had Bootpicker on my Samsung monitor attached to HDMI#2. Subsequently, I updated to 12.2. Since then, with each OC release I've not been able to update my macOS and I've lost Bootpicker.

Any ideas welcome, cheers

Found the problem: the issue is having OC installed on a 1GB USB Thumbdrive formatted exFAT on the primary partition that was blessed (no EFI partition). Booting to OC and macOS 12 worked fine but I lost the BootPicker and the ability to do Software Update with the VMM flag ON and SMBIOS Off.

I reverted to installing OC on EFI partition of 4GB USB Thumb drive formatted GUID/HFS+ and got BootPicker and Software Update works again.
 
On my other cMP4,1->5,1(Early 2009) Radeon HD 7950 with upgraded WiFi/BT running macOS 12.1 and OC 0.8.0 with default config.plist. I have a single LG monitor connected and during boot I don't get BootPicker. On the HD 9750 I tried both outputs DVI and HDMI but no BootPicker at startup. Eventually I get the Apple logo progress screen and then Finder.

Any ideas welcome, cheers
 
Is anyone else having a stutter issue? When playing videos (even youtube) every ~5-10 seconds I'll experience a stutter.

Happens on both 0.7.9 & 0.8.0 package. 5700 XT GPU

Which codec?

Only shuttering in browser? Or it happens in any apps / players?

Which OS?

Seems to happen everywhere.

Safari, Chrome, VLC (x264)

Monterey 12.3.1

Audio itself doesn't stutter at all it's just the video that does it.

Now that I look for it more even scrolling in browsers if I am constantly scrolling it'll have a stutter as well.
 
I created a new "easy to install package" as per many requested (based on the official OpenCore). [The attached package updated to 0.8.0]

I just belatedly put 0.7.9 on in place of 0.7.5 - amazing, boot screen appears almost immediately after the bootup chime/gong, so fast now on my NVME. Excellent. :)

In terms of stuttering, none experienced - I watched Autogefuhl yesterday at 1440p resolution with no issue.

I'm on the dual 3.46 Mac Pro on 12.2 Beta (21D5025f) Monterey (no time to upgrade it yet after surgery in hospital).

Try Chrome -> settings -> additional settings -> system -> disable Hardware Acceleration.

Then check if that make any difference (inside Chrome).

Still has the stutter issue.

Noticed even screen saver has stutter issue.
Then it's not related to HWAccel.

If you have spare drive, then you can try if clean installation fix the issue.

If nil help, then may be other hardware issue (since 5700XT is widely used for a while now. So, I assume that's not macOS GPU driver issue if can't be fixed by clean macOS installation).
