I still use my 2010 Mac Book Pro but with the large files from the 5DS R and the 5D MKIV some processes are very slow. Overall it has been a workhorse. I did put an SSD in it about 3 years ago because it was dropped (not by me) and the original HD was damaged. It was a simple fix and my time machine back up worked flawlessly. It just works and works without issues or any type of maintenance. Sorry to hear that a new MAcBook has frequent glitches.
