The Dell OptiMac Big Sur/OpenCore Thread - For 7020/9020 Optiplex Desktops

[trs96]

I will make my own 076 version when I have the time this week).

Here's a great idea. Adding this info to the beginning makes it much easier to determine important facts about it, like the OC version. The # before Board etc. means it's commented out. That is required when using this way of providing the info at the beginning of a config.plist. Here's how it would look for the Dell Optiplex 9020:

You could also add in the #Build Date if you so choose.

"Sleep Wake" failure in EFI has come back...

Failure code:: 0x00000000 0x0000001f

As I have AMD GPU, I don't use actual "sleep" but only turn the displays off by using hot corners or set display automatically turned off in Energy Saver setting. There has been no problem with this setting both on Catalina and Big Sur in a single boot setting. However, after my configuring my Optimac with a dual boot of Win 10 and Big Sur, every time displays go off the system never comes back when I hit the keyboard or move the mouse. Just black screens. I have to force reboot the machine.

I followed the instruction in post #2 and used provided EFI. Any thoughts?

I did nothing but it's gone... weird...

Using ProperTree with macOS Monterey
​

I tried using ProperTree with Monterey recently and it didn't work. So upon looking at Github for a solution I found that we'll need to use the Intel Build of Python for it to work correctly in Monterey. Here's the details of the fix that corpnewt offers.

• ProperTree opens to a black window on macOS Monterey (12.x)
  It appears the default tk implementation that ships with macOS Monterey doesn't display correctly. A workaround is to download and install the intel build (not "universal") of python 3.9.7 from python.org (direct link here) which has a compatible tk bundled, then use the buildapp-select.command located in ProperTree's Scripts directory to build an application bundle targeting the installed python's path.
• ProperTree cannot open or save plist files on macOS Monterey (12.x)
  This appears to be an issue with the "universal" installers from python.org. The solution is to use the intel-only build. The latest of which is 3.9.7, direct linked here. After installing, use the buildapp-select.command located in ProperTree's Scripts directory to build an application bundle targeting the installed python's path.

After you download and install Python 3.9.7 then run the buildapp-select.command and enter 2 here:

You will also need to install the developer tools.

Finally in the ProperTree preferences pane, set it to not expand children when opening.
Simply uncheck the box and it will open up just like PlistEdit Pro app does.

Finally a day off!

Please remove all serials and SmUUID before posting your EFI. Thanks.

The mouse stuttering can likely be fixed by changing your Device/Properties Graphics section. Look at mine in the Macmini7,1 EFI folder.

Also remove the duplicate boot-args

My system crashes for no reason

The very first line says "memory corruption"

Test your ram with Memtest or just use one stick of ram at a time to see which one causes the panic.
Also try different ram slots as sometimes those can be problematic.
