MP 1,1-5,1 Music App crashes after upgrade to Big Sur 11.6.5

[Peter.QC]

Hello, This is my first post on the MacRumors forms, so I hope I'm doing it right!
I just recently upgraded the OS on my cMP from Mojave 10.14.6 to Big Sur 11.6.5 using the 0.7.9 OpenCore preconfigured install package. Thanks to all the people who put together this package and tools. Everything works great except I have one issue that I have not been able to find any info on... The Music App crashes instantly upon launch. I get the message : Music quit unexpectedly while using the CoreLSKD plug-in.

Has anyone experienced this problem? Is there a fix?

Thanks for any help you can give me!

System details :
cMP 5,1 2 x 6-core Xeon @ 3.06GHz
Radeon Sapphire RX580 Nitro 8GB (3 monitors, and HW acceleration working)
Updated WiFi / Bluetooth Broadcom BCM43xx (working)

Does iTunes work? You can install it on Big Sur using Retroactive.

Thanks for the tip. I'll certainly give this a try if I can't get the Music app to run!

I'm not certain about the following, but there are many reports of issues with the Nitro versions of the RX580 on the cMP. The link below is one example of many more. My guess is that the issue with CoreLSKD plug-in has something to do with the Nitro version of the GPU and not the Music app/Monterey itself? Just a guess, though. I ran OC 0.7.x (earlier versions than 0.7.9) with Big Sur (all updates) along a Sapphire RX580 and then OC 0.7.9 with Monterey and the same Sapphire RX580 (and more recently with a Radeon RX5700) -- Music app always worked/works as expected, no issues.

Yes, PowerPlay settings from Nitro+ firmware shows us that is a 238W card. Some people use it successfully, but some had to use Pixla's mod. It's a bad choice, power and fit wise. Even if it works with your Mac Pro, you still block a slot, since it's a 2.3 wide card and will block slot 2...
