I use a Linux distro with kde, so I have a lot of customization available. I like trying other distros in VMs, but stuff like windows (no need to copy really kde is similar by default) and Mac is a pain in the ass to use that way. so, I want to know what your os does that you think I should copy using kde’s customization. I’m looking for Mac in particular (bc I haven’t used it before) but any OS or desktop environment is fair game.
download a virtual machine app (I’d recommend virtual box, boxes is great too but iirc its Linux only), download the .iso file (this is the installer) for the distro you want to try from the official website, in your app of choice create a virtual machine and select the file you downloaded. from there you just follow the installer. it may help to look up how to use the app you chose bc VMs can be a little iffy. if you’ve ever used an emulator, it’s a similar process but with ISOs instead of roms.
