I've had my Mac mini 2018 for just over two years. I am concerned that there has accumulated dust inside of the computer – not because anything seems problematic at the moment, but my experience with MacBook Pro laptops has been that you need to clean them every two years. There is usually a dust coasting landing on top of the Mac mini, so I am suspecting it needs to be cleaned also.
If I were to open the Mac mini and attempt to blow it clean with compressed air, would that void any remaining warranty?
NB: I believe my product is actually already outside of Apple's limited warranty. However, does Apple not want consumers to open the Mac Mini, so that if something were to break at some time, that an authorized service shop would refuse repair?
