Question: Fan Noise and lagging
My MacbookPro is nearly 5 years old now and has suddenly started having problems with constant lagging no matter what I am doing on my laptop. As well as the fan always being on high, despite my laptop being cold. It is very noisy, and hard to use the laptop as the lagging is interferring with what work I am trying to do.
I have tried restarting my MacbookPro, clearing history, clearing caches, checking all my iOS are up to date and making sure there is enough memory space. I haven't dropped or caused any damage to my laptop so am wondering if there are any solutions anyone can think of that I would be able to do myself.
MacBook Pro, macOS High Sierra (10.13.3)
