I was considering that option. How much RAM do you think I'd need? My work machine is an old thinkpad with 12GB but it does slow down/freeze fairly frequently (this might be a because of other reasons though) so I am thinking that 8GB would never be enough. Is macOS less or more resource intensive?

Good point - I don't really know, depends on your needs I guess. I don't do very much memory-intensive stuff so 8GB has been fine for me.

What kind of tasks do you usually do? My old Laptop was already 6 years old when it died so I have no point of reference haha.

Usually a light virtual machine and a bunch of browser tabs. Watching videos. Some coding.
