Installation of Mac OS El Capitan on Mac mini M2 Pro / crahses - HD Issue?

Thanks for the excellent idea of providing setups for UTM here for much macOS versions. On UTM 4.16 I started several attempts yesterday to install a virtual machine with El Capitan on my Mac Mini M2 Pro (16/512) using the Mac OS 10.11 preset. The process runs flawlessly up to the point where the Mac OS is supposed to be installed on the hard disk. The error message appears that the Mac OS cannot be installed on this hard disk. There is also no drive of sufficient size visible in Disk Utility. I have tried several times, each time before a new installation attempt, to set up a sufficiently large hard disk in the preset. But this does not work for some unknown reason. Also in the virtual machine label - below machine and memory next to the hard disk icon a much too small size - mostly small than 1 MByte - is displayed. Probably this also leads to the fact that at the latest when trying to use the Apple Disk Utility the virtual machine crashes. What am I doing wrong?

Thank you for the quick tips!

  1. enlarging the hard disk or deleting and recreating in the configurator did not lead to any improvement.
  2. as a test I installed the last 3.x version (3.24) for Mac OS. Now I can use Disk Utility to edit, delete, partition the disks without crashing. However, when trying to install the system, it still gives the error message: "copy this application...." See image above.

I have found - hopefully - a solution with the help of the error message in the depths of the Internet. The ISO file I used, which I still had from El Capitan times, does not seem to be suitable for this type of installation. I will create a new ISO later and then report here if it works.

Unfortunately, that did not work either. I made a lot of attempts yesterday. But unfortunately no success.

  1. the Installer.app conversion recommended in the program window does not work on the M2 Mac because I cannot install the OSX.DMG in the Applications folder.
  2. so I used terminal commands to convert an ElCapitan.DMG (downloaded from Apple server) to an ISO file. But with this ISO no (third) choice for installation appears in the boot loader. Also an attempt with Yosemite (OSX 10.10) does not work.
  3. the ISO file I had used before, which at least led up to Disk Utility (see above), I found here https://archive.org/details/macos-collection .
  4. still hoping to find a solution. Otherwise, I'll have to go a completely different route, as I desperately need El Capitan on my new M2 Pro Mac for an old accounting program.

So as before I am very grateful for any helping tip.

Thanks :-) After a long day now the success. I found out that my application runs from OSX 10.7 to 10.11. With Lion and UTM 3.24 I came to success. I extracted the InstallESD.dmg from the DMG as described and assigned this as the installation drive. In your config file I later only enabled file sharing on the network. Thanks for the prepared config files. The virtual machine has been running on the M2 for a few hours now. Great. I was about to give up today and switch to Parallels. Then I had to learn that on Apple Silicon only OS 12 and 13 are supported. Your work and UTM are really a stroke of luck.
