Just bought my first ever Apple computer - MBP 2017. It came with Sierra. I'm wondering, since High Sierra is out too, should I update and go through the learning curve on the latest possible OS? Having a bit of a tough time understanding how things work on a Mac (never used it before) so I thought it would be best if I do all the learning on the latest possible OS. But I don't want to rush into it and get a buggy version. So is High Sierra completely bug free to install? P.S. I'm the type of person who is last to update iOS just so I don't have to face any bugs.
