Don’t forget that at the moment, all current macs are also PCs. So if you really need, you can install a windows 10 partition and boot into windows on your mac. I use Parallels and it’s really fast and reliable for the windows software that I need to run in addition to my Mac software.
I have also worked with everything from SD to 4k dpx files on the mac, it’s my reliable machine of choice!
As for software, I keep getting more and more impressed the more I use DaVinci Resolve. If you’re working only up to 1080p, their free version can’t be beat. I do own the studio version, and it’s becoming the ideal tool for professional work across the board. (The only flaw, is that I wish it had many of the plugins of other apps, but this is quickly changing to include resolve as well.)
Best of luck!
