I watched a video about MacOS running crazy good vith virtualization... and they say that you don't need any configuration... Is this true? Can anyone do it?
I tried running VM's on a couple of my Ryzentosh boxes, the only one I got to run on it is VMware, (make sure to enable virtualization in your bios). I also wanted to add something about your question about running your icloud account with hacks and normal apple devices, as long as you make sure you have your serial numers, uuids & roms set correctly there should not be an issue... I have 8 hacks, (5 are Ryzentoshes) and an iphone, 2 m1 ipads and 2020 12" ipad all one one icloud account with no issues. BUT, I did have an issue where I had to create a new icloud account when I first got into the hackintoshes and was using clover boot loader and it was messing up the serials and got my account blacklisted. So just make sure you read up on how to make sure you have valid Serials and how to set up Rom before you connect whatever machine you are using to your icloud account. Worse case, if you get an issue where you can't log into icloud services anymore, (banned) just create a new icloud account with a different email.
