Hot VS UTM

iMacs are sensitive and unusable if the room/environment temperature goes up 1-2 degrees. Once an iMac reaches temperatures that exceed its cooling capabilities, it will reduce the Scheduler Limit. This OS protection slows your computer down to a % of its actual performance. It's designed to reduce load down to a level that the computer can cope with, given its temperature situation. A tool called Hot will reveal the current scheduler limit, and you'll be able to verify this is the problem.

I'm using Hot: https://github.com/macmade/Hot

Use https://github.com/macmade/Hot to read temps instead. I don’t trust cleanmymac.

https://github.com/macmade/Hot show you the deets.

The Hot . app is great for showing how hot or cold my laptop is running, and whether it has throttled.

You can use the tool "Hot" (https://github.com/macmade/Hot) to check if we are investigating in the right direction.

If you have TrollStore then install the HV version of UTM to try for yourself: https://github.com/utmapp/UTM/releases/latest/download/UTM.HV.ipa

Researching a little showed that this is basically what can be expected running x86 emulation and the systems will just be wonky and slow, although it was running flawlessly, just slow.

There seem to be ways to use Rosetta2 inside a VM [0] to then translate binaries but I found no official support or documentation (using UTM+QEMU that was), this would be such a cool feature, at least there are discussions about it [1,2]

UTM is open source too though: https://github.com/utmapp/UTM#license

UTM makes it easy to set up and manage macOS and Windows virtual machines. This can be especially useful for developers such as Tauri contributors who need to test their applications across multiple platforms, or for those looking to experiment with different operating systems without affecting their primary system.

If you don't need high performance and want to use the OS only occasionally, check UTM.app, at https://mac.getutm.app/ (or https://github.com/utmapp/UTM ). Free, open source.
