I have tried smc and pram reset, I can’t reinstall new Mac OS due to overheating and switching it self off. Unless the MacBook in question is exceeding 80☌ while idle with no absurd CPU usage or rogue processes (check with Activity Monitor for process CPU usage), I wouldn't see any cause for concern about the temperature of your MacBook. I have MacBook Pro, the fan doesn’t turn on by itself but can be turned on manually with Macs fan control application. It's also important to remember that OS X will shut your computer down if it gets too hot (>100☌ IIRC). Apple does not offer any fan control application to access. Apple fan control is via hardware (SMC services) which works via the core OS (and not controllable by the user). Between burnt out fans & systems it is a costly venture over the long haul. I don't mean to get too technical, but you can think of the entire unibody as a rather large heatsink that conducts heat away from your Mac (another reason why sometimes the entire computer feels warm and not just one region). Sadly, from experience working on Mac systems over 20 years this band-aid solution is not ideal. My 13" Retina MacBook Pro, mid-2014 version can get rather warm when idle (~50☌-60☌) especially if placed on a non-heat conducive surface like a mattress or my legs. direct sunlight in a tropical country), your MacBook shouldn't get too much hotter than its regular idle temperatures.
Unless you're using your MacBook in an abnormally warm environment (i.e. Considering that the entire line of MacBooks have no fans, I wouldn't be surprised if it got to the range of 50☌ while idle.Īpple only supplies minimum and maximum ambient temperatures the specified ambient temperature range for your MacBook 50° to 95° F (10° to 35° C) ( source).
