I have a 2009 and 2013 MacBook Pro (MBP). My wife has a 2015 MBP. I'd love to maximize their lifespans by taking care of them physically.

What there any physical maintenance that I can perform on our MBPs to maximize their performance and life, and how often should I perform these tasks? Which of these tasks can I perform at home, and for which should I bring my MBP to a specialist (e.g. for part replacement)?

I'm thinking about removing dust, cycling the battery a certain way, restarting regularly, storing it for a certain length of time, cleaning external ports, replacing parts after a certain amount of time, etc.

  • Your question is both too broad and primarily opinion-based. From my point of view, as long as you use common sense and generally look after them, you should be right. There's no need to change parts until you need to (e.g. a hard drive fails, a bad memory module, etc). So, the number 1 thing I would recommend is to ensure you have a backup regime in place (e.g. by using Time Machine). So, invest in a number of external hard drives and regularly backup your data on all three MBPs. – Monomeeth May 21 '17 at 10:15
  • Other than taking the back cover off and blowing out the dust, there is no physical maintenance you can do (and yes, this includes that battery/power cycle dance you described). However, the key bit of maintenance you can do is what @Monomeeth suggested and that is to have continual and up to date backups. The computer will die at some point - there's no reason your data has to as well. – Allan May 22 '17 at 1:36
  • @Monomeeth, why don't you post this as an answer? Sometimes broad questions call for broad answers, this seems to be one of these cases :-) – nohillside May 26 '17 at 6:48
