I won't have physical access to this machine until mid-August now, so it probably won't be available again until then. m

At least one that is currently in use has 8G - I would assume the others also have 8G. Would that work or you need 16G? How much does the current buildbot slave has? -- Sincerely yours, Yury V. Zaytsev

OK, I can check the other Mac Minis now and see if I can use that. I will have to reset machine to the latest version of Mac OS, whatever it is.

I can also cross the river to the enemy territory (Düsseldorf) - anything in 50km radius is OK... -- Sincerely yours, Yury V. Zaytsev

Oh man, mac life is hard... just bricked one mini, trying to erase the hard drive and reinstall the OS :-/ Apparently something went wrong during the erase, and now everything including El Capitan panics upon booting the installer, probably due to a kernel bug in com.apple.driver.CoreStorage, which leads to the meltdown due to this particular evil type of disk corruption. I wonder which options do I have other than taking the thing apart and zeroeing the hard drive with Linux - just odered a Thunderbolt cable - maybe I could get to the drive using Target Disk mode and zero it without getting it out of the machine... Gonna try my luck with another mini tomorrow. -- Sincerely yours, Yury V. Zaytsev

Boot from a usb installer image and you can clear the disk and install to it.
Of course, I've tried that already with an USB installer for Catalina (APFS support) and El Capitan (pre-APFS) - both installers panic on boot while probing local hardware because as soon as they find the disk and try to read the partition table something goes kaboom. Internet Recovery leads to the same results, because basically it's just another delivery way for the installer, but as soon as it starts booting were're at square one. Is there some way to zero the first blocks of the drive from EFI :) ? Like in the old good days when Sun still shined, I could enter OpenBoot by pressing the magic "Stop-A" button and enter the Forth interpreter to do stuff like that... -- Sincerely yours, Yury V.

Hey Matt, Awesome, it worked! Ubuntu 20.04 booted without skipping a beat and after zeroing the disk, Catalina installer was able to recreate the Fusion Drive and install the OS. Will try to see if I can get it set up as a buildbot slave according the the instructions you that you've posted earlier... -- Sincerely yours, Yury V. Zaytsev
