Yeah, instead of spending (even used) about 3 times the price for (maybe) 10% better average quality hardware (the OS isn't any more stable then Windows because if Windows wasn't so dominant the hackers/viruses would be aimed at the Apple OS instead of the Microsoft OS, and hacking/virus/ransomeware, etc. are the major cause of instability, not the OS itself), you might just get a good video converter and run with that. While Apple would like everyone to believe they are the standard in everything graphical, those days are pretty much past as the Internet has driven the industry to the more broadly based Windows compatible video standards exactly because fewer businesses are willing to spend 3 times the price for the same product. I've converted probably 15 graphics companies from Apple based to Windows based graphic and it's just not that hard and they have noticed little to no real problems even with their "Fapplnatics." And they love the much lower prices and competition.
Another options, though it's tough, is to make a "Hackintosh" -- a PC running on non-Apple platform. Apple is against it and it says in the EULA that you cannot to it...but what they mean is that if you do you are on your own. I've done it a couple of times and it's tricky, but can be done.
Just my thoughts on the matter. I do hope I haven't ignited any PC/Apple wars. I do have an Apple and I do use it with my various other devices, including Linux, Windows, Android, and even Chrome, so I'm not saying Apple is not as good as Windows or anything else. I just think it's way overpriced for what you get and too controlling of your actions once you get it.
