I upgraded my Catalina build to Big Sur. Main usage for this machine is office stuff and audio post production.
The Build
Everything stayed the same, so I didn't upgrade any hardware. I used my second M.2 SSD as a backup drive for Catalina, and, later on, as a test drive for Big Sur which makes it very easy to test out the different things.
When Big Sur came out I had no luck with a stable installation. It installed with no issues. But than, after awhile of usage, the system froze. I couldn't find out why, so I decided to wait for optimized OpenCore bootloader. With OpenCore 6.7 I managed to get BigSur installed and running. Well, as I figured, I didn't convert my earlier oc configs correctly to the newer versions, but you can't fool me twice config.plist! (Pprobably it will, but yeah! )
BIOS Settings
BIOS is the latest F15a.
1 Save & Exit → Load Optimized Defaults
2 M.I.T. → Advanced Memory Settings Extreme Memory Profile(X.M.P.) : Profile1
3 System → CSM Support : Disabled
3 BIOS → Fast Boot : Disabled
4 BIOS → LAN PXE Boot Option ROM : Disabled
5 BIOS → Storage Boot Option Control : UEFI
6 Peripherals → Initial Display Output : PCIe 1 Slot
7 Peripherals → Above 4G Decoding : Enabled
8 Peripherals → Intel Platform Trust Technology : Disabled
9 Peripherals → Network Stack Configuration → Network Stack : Disabled
10 Peripherals → USB Configuration → Legacy USB Support : Auto
11 Peripherals → USB Configuration → XHCI Hand-off : Enabled
12 Chipset → Vt-d : Enabled (disabled in the config.plist but if you use Windows you can enable it)
13 Chipset → Wake on LAN Enable : Enabled
14 Chipset → IOAPIC 24-119 Entries : Enabled
15 Chipset → Integrated Graphics : Enabled
Smart Fan Settings set to silent mode so all 6 fans are below 1000 rpm and nearly inaudible.
OpenCore
I followed the OpenCore Desktop Guide for my Coffee Lake CPU. I also used the Hackintool and the New Beginner's Guide to USB port Configuration for mapping out my USB ports.
I switched from iMacPro1,1 back to iMac19,2. Mandatory needed boot-args: agdpmod=pikera and igfxonln=1 without this I got stuck at booting "Nvidia IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0 error".
For audio I chose first the boot-arg "alcid=11" instead of the default "alcid=1" and later added it to Device Properties in the config.plist instead.
Mapping out the USB ports with USBMap tool like the guide mentioned wasn't as clear as with Hackintool form me. But both work.
Conclusion
I got working iMessage, DRM playback, all USB ports, both UAD cards, sleep/wake and Bluetooth via USB. Since I don't have WIFI installed, Airdrop isn't available. The app MonitorControl, which is controlling the brightness of my screen, is working very nicely.
So everything so far tested is working great. Nevertheless, I did get a freeze with a green screen two times, but I don't know what's causing it. Need to investigate more and report back here.
Right now I'm running the latest OS 11.2.2 and OC 0.6.7.
- Updated to OC 7.0 and OS 11.4
- Updated to OC 7.6 and OS 11.6.2
Thanks again to this awesome community and happy hackintoshing!
