Then I downloaded my seminar.pro app (which is sandboxed and notarized), did run the installer, agreed to rosetta install, and surprise: my app still runs without any error!
Seminar.pro is an app I developed with Xojo for macOS, and I need to maintain it for the time being.
Latest version is built with Xojo 2020r1.2 (later Xojo versions totally mess it up and I do not have the time to rewrite tons of code)
I just installed macOS 12 with UTM on my MBP M1 Pro running macOS 13.
And it works much faster compared to using Parallels 17 (I don’t have 18).
With Parallels I only could use 4GB as memory and 2 cores. UTM can use as many as you want (for both) which is awesome and boost performance a lot.
One thing I cannot get to work is sharing files between the host OS and VM.
Anyhow, I bought UTM on the AppStore (I know its available for free too but for 12eur I gladly support this awesome VM tool).
Ok. That requires additions to the software, which UTM probably haven’t added (yet).
About connecting to the server directly, that still should work.
Alternatively, if you want drag & drop and clipboard sharing, you can access the VM using Screen Sharing.app. On the client, enable Screen Sharing and then on the Host, in the Finder, go to the Network tab - double click the VM, and you’ll see a “Share Screen” button appear.
