In my experience, however, relatively few Mac users do more than upgrade the RAM and replace the HDD/SSD. Software is not magic – it cannot change the internal video card or update the CPU, although there are still quite a few people who would like to have that option. Personally, I have a hard time criticizing Apple if my seven to ten year old Mac does not perform quite as snappily as I would prefer. People often complain about new OS releases, but you have the option to stick with the current version, if you choose. But it is nice to know that Apple often improves its products over time with new software releases.
