See...think of why you don't want to leave your Mac. That's how a Linux user feels when forced to use a Mac by an employer. Sure, there's a lot that can be customised. But it's a pain to go through that and build that muscle-memory on Mac and then go back home to your personal linux computer and have to re-adjust. It's simply faster and more comfortable to use a familiar OS. My relatives sometimes ask me why Microsoft changed Windows so much. They yearn to use Windows XP, because they got so used to it, and they dislike Windows 8 and 10.
