Mid-2014 MBP Running Hot After New Battery In August of this year I had a swollen battery changed out of my mid-2014 15” MPB 16 Gig Ram, 1TB HD. The computer worked like normal until the last week when the bottom back panel started to get really hot to the touch. It isn’t burn you hot but is only about one level below that so to speak. I took it to Apple yesterday and the computer passed all their diagnostic tests. They are now at a point where they want to do an install of Mojave but first wiping the hard drive clean. Given how unreliable Time Machine has been (twice in the last year all backups were lost and a full backup had to be created) I don’t trust it to get all my software reinstalled and since many applications are older non-subscription based ones that cannot be purchased again I am not sure I want to take this chance. 1) Has anyone heard of a clean install of an OS resolving a heat issue? 2) If this OS install doesn’t solve the issue, what is next? 3). I know the Mac will shut down if it get’s too hot but that is only if it gets too hot from performing computer tasks, right? If something is wrong with the power supply the computer shutting down will do no good. I say this because the heat issue I experience happens when the computer is plugged into AC power but is just sitting there with no applications running but the screensaver. If it is running hot like this due to a non-system or application issue, how will the computer turning itself off do any good? I am not sure if I have explained this concern very well. A weird analogy would be if a person held a propane torch close to the computer it may sense it is getting too hot but shutting itself down won’t turn off the propane torch. The biggest concern is if I go with a fresh operating system and that doesn’t solve the issue. Where to next and if I have to buy a new MBP I just assume has the current one as is and just run the battery down for fire prevention and keep it around for archive purposes. Thanks. Sorry for the long post. Greg

Start here - See how apps affect Mac performance, battery runtime, temperature, and fan activity - Apple Support - and see if any of the suggestions in the article help. Particularly, follow the links at the bottom of the article too.
