How is Apple able to sell OS X for a profit when it's based off Linux which is open source/free?
Isn't that illegal?
They don't. Upgrading is free at any time and it comes free with every mac.
Microsoft is a software company and gives out Windows 10 upgrades for one year for free because it has spyware to sell your data anyways.
