I discourage transplanting old SSDs because they can cause unexpected issues that we may not be able to help you with. But you're welcome to try.
I don't recall "SuperIO" being present in any version of the Designare BIOS. F9g is a good one to use; CFG-Lock is disabled by default.
Good luck with macOS installation!
I know you discouraged me to « transplant » my working SSD Mojave 10.14.6 (Dell Optiplex 7020 old DAW) but it worked...
Everything works so far:
- Sleep;
- CPU power management;
- NVRAM, iMessage;
- audio;
- the two Ethernet ports (I won’t use any WiFi);
- Thunderbolt, at least the USB C 3.2 part, tested with my Samsung T5;
- USB ports, I used the provided USBPorts.kext and modified it with my chosen SMBIOS (iMacPro 1,1).
I had to deauthorize a bunch of software prior to the operation: Paragon NTFS, CDock and a lot of audio software and plugins.
I‘ve simply modified the content of the EFI, following almost to the letter the config.plist mods in the first post. I kept a couple of kexts (AppleALC, Lilu, FakeSMC) without replacing them. The OCQuircks kexts v4 did the job, thanks a bunch! Also stayed with Clover 5099.
As GPU, I bought an ASUS Strix EVO OC 4GB for cheap: fans aren’t running until temperature rises to 55 Celsius degrees and this card doesn’t need any power from my power supply. For the moment, I inject ATI and ACRE FB with Clover. I also had to add the AGDP patch to use my two monitors. It’s reported as Radeon Pro 555 by MacOS, interesting!
What’s remaining:
- Finalyzing the Windows 10 SSD transition;
- Connecting my two others data HDD’s (mechanical);
- Properly tying and hiding the cables and adding back the two side panels;
- Verifying that iTunes Movies that I have bought are functional once I reauthorize the computer (should be ok me think as I use iMacPro SMBIOS);
- Connecting all remaining USB devices. All USB2 things will connect to my Amazon Basics powered USB2 hub (this one connected to the USB2 only ports on the Designare). Then, my Lacie USB3 and my Seagate externals HDD’s. My Focusrite 18i20 2nd Gen will be connected to the other remaining USB2 port awaiting the arrival of my Quantum 2626 Thunderbolt AI...
This machine is whisper quiet (all fans set to « silent » in the BIOS) even without the side panels. CPU temp is around 30 Celsius degrees idle...
To resume, a big thank you for you Casey and all the people in this thread!
