utmconfigs VS Opencore-Legacy-Patcher

What I did, is downloading a preconfigured file via this site: https://github.com/adespoton/utmconfigs/blob/main/README.md clicked on "Got to file" and selected the one for Mavericks (10.9). After installing it on UTM, you will see which steps you have to follow on the right side. Then I downloaded an ISO file and installed that one according to the earlier mentioned steps. Et voilà!

You’ll need to use UTM instead and import the Sierra config file from this GitHub repo.

Adespoton on GitHub made UTM config files to allow you to install a macOS VM on Intel Macs or AS Macs for older versions of macOS. Keep in mind a few things:

This and this were both fantastic starting points, and got me up and running if I remember correctly. The github repo with the prebuilt UTM config files is spectacular. For El Capitan I'm pretty sure I started with the prebuilt utm file and booted it with my own El Capitan installer ISO.

There is a guy who makes basic machiene setups for utm you add the OS. Looks like the Mac99/screamer model can only go back to 9.04.and the quadra model doesn't work.

I've been trying to run MacOS X 10.1 though UTM, but I've been encountering various issues. I downloaded the .utm from https://github.com/adespoton/utmconfigs and the .iso from https://archive.org/details/mac-ox-x-10.1-internal-edition, but when I try to run them I get this error: qemu-ppc-softmmu: -drive if=none,media=disk,id=drive0,file=/Users/alessandrowda/Downloads/OS X 10.1 (config only).utm/Images/OS X 10.1.qcow2,discard=unmap,detect-zeroes=unmap: Could not open '/Users/alessandrowda/Downloads/OS X 10.1 (config only).utm/Images/OS X 10.1.qcow2': Operation not permitted.

At a guess I would say probably using OCLP - https://github.com/dortania/OpenCore-Legacy-Patcher - lots of life left in old Mac’s using that tool !

I had this issue, too. But luckily, I've got a solution. First, you'll need to check your MacOS Sonoma version. If you're using 14.1 beta, this method will NOT work. In such cases, I recommend installing the official 14.0. Thankfully, this commit (https://github.com/dortania/OpenCore-Legacy-Patcher/commit/1aee2e5dfa12d10e218a51e4151ac2e96705ae9e) solved the problem! However, the latest OCLP 1.0.1 still doesn't have it. To use it, you can build OCLP from code or use the OCLP Nightly link found here. After you find the nightly link and download OCLP, build it onto your MBP, and after rebooting, install the patches. If you look carefully, you'll see that 'experimental T1 Patches' will be available in the list of post-installation patches.

From what I've assessed reading other posts, Monterey (Ventura has USB & stability issues) with OCLP 0.6.7 is the most stable install for this device (have not yet seen any reports using OCLP 1.0+, although happy to see some new non-Metal fixes going in). This is a bit of a bummer, as Monterey will not likely receive updates past end of 2024 (next year).

I'm not taking a position on OCLP being trustworthy or not, but at least the project appears to be 100% open source [0], which is more than we can say about Apple.

Have you explored https://github.com/dortania/OpenCore-Legacy-Patcher?

I have used it before and, in my experience and everyone else I know who has used it, the vast majority of time the newer versions run absolutely fine with no issues. Occasionally some newer features don't work, but I'd but confident that 2015/2017 iMacs would be able to run the latest version no problem.
