Yes to bullet point #2
Bullet point 3.5 - Final cut pro, Motion, Logic, Compressor and a couple more from the Apple package.
You highly recommend for an abundance of reasons, very well then.

Please forgive my ignorance but is there a re-licensing fee or just a request and re-install ?

Is there any reason to leave the boot test USB in during the final steps?
Thanks for removing the big file! Much appreciated.

The very nice thing about apps purchased from the Mac App Store is that they do not need to re-licensed! We only have to download them again from the App Store.

So I think the best long-term option is:
  • Follow the Catalina 10.15.4 fresh installation guideon an empty NVMe SSD.
    • We shouldn't delete the existing Mojave SSD so a new or empty NVMe SSD should be used.
  • This will give you the best reliability.
  • It will also let you retire the old iMac14,2 SMBIOS and cleanly switch to the new iMac19,1 SMBIOS.
  • It should also be a relatively smooth experience. I think we are seeing too many problems with the current approach of migrating from 10.14.3 to 10.15.4. So it should be a smooth experience to install Catalina 10.15.4 directly on a new or empty NVMe SSD.
  • However, you will need to download the full Catalina 10.15.4 install package (8.6 GB).
If you have any problems or questions, feel free to ask.

Thanks. I tried for months with Catalina, could not solve my system freeze ups with a 580 or a 5700 xt on this hack. My MacBook runs fine, and so does Mojave on this hack. It’s a mystery for me so far.
Have you tried Catalina on just the iGPU? This would rule out any other components?

Thanks Casey,

I have quite a few NVMe drives around so no problem with that.
Your experience here and other members is invaluable to say the least. I was sooo thinking that this upgrade method is just asking for glitches and No Joy lol

Thanks for Verifying the Re-install answer.
I contributed $10.00 here just yesterday and wonder if it shows anywhere in our account? I love Final Cut and Logic so will do whatever it takes to keep this forum alive and pumping :thumbup:

Thanks for the feedback. I used a DP port successfully yesterday on my PowerColor Red Dragon 5700XT. Please try each of the DP ports to see which one(s) work. I'll do the same with my PowerColor.

Also please try enabling WhateverGreen (just remove the -wegoff Boot Argument) to see if all video ports come back and performance is still good.
I don’t use WEG at all. Instead I use pike R black screen patch in Clover. Maybe that patch will work for 5700, also for enabling all the ports.

@jaymonkey reported the same findings. So I'm curious to see if anyone finds a real-world application or task that benefits from the kext/SSDT.
Radeon booster results with apps and GB on RadeonVII 10.5.4
Tested with WEG enabled and shikigva=80. No changes to config other than adding kext/ssdt. Netflix/safari and prime/chrome working. Projects are from my my workflow. Observed 30-35 % improvement in benchmarks and 5-15% improvements in project rendering. Fans are louder with the ssd active, but not unbearably loud.

Funny you ask. I’ve literally replaced everything: motherboard, PSU, CPU, RAM, different 5700, RX 580. The list goes on. I’ve also tested with everything unplugged/minimal setup with different mouse & keyboard even. No luck. I guess it’s Karma or something.

Thanks Casey,

I have quite a few Nvme drives around so no problem with that.

Mighty Nice of you @CaseySJ :thumbup:

Just to clarify, I didn't want you to think I was that dense hahaha!
I meant I was sooo thinking that the micro guide from Mojave to Catalina followed by Catalina Mini guide install, was just asking for trouble NOT what you recommended which seems very streamlined and full proof, if one does not skip a beat! Thanks once again Casey :D

Fans are louder with the ssd active, but not unbearably loud.

You can likely modify the PP table in the SSDT to get the fans to slowdown a bit and they they will be less loud.

Its also been noted that the power profile could be implemented via property injection rather than SSDT. This seems more flexible but I'm not clear on exactly how to inject the power table through device properties. It doesn't seem to do that much anyway.
