MBP 2015 retina 15” very slow.
I have exactly the same problem with MBP 2015 retina 15” very slow . The cpu fans run load though from time to time. Sometimes after a reinstall or fresh install it works for a few days perfectly but same slowness comes back after a while consistently.
Ssd wasn’t the problem as I used an external bootdrive to boot Macos from also replaced with another ssd. Original & high speed ssd . ( sintech)
I wonder if it has to do with the graphics card as every times it runs well for few days and I install imovie , adobe IA or mpeg driver for vlc it started to be slower. Could it be the graphics card?
