Hi,
Since i upgraded my MacBook Pro retina 2015 from Mac OS X El Capitan to Mac OS sierra,
I noticed that the internal temperature on my Mac is much higher than before while doing the same load of work and the fan also keeps running so as to cool it down which was normally off before as here was nothing inciting to heat like that.
I personally think that the problem comes from Mac OS Sierra, What do you guys think about it?
MacBook Pro with Retina display, macOS Sierra (10.12)
Use Activity Monitor to find out what is using up so much CPU. Often you will find something is not right and something you brought forward from your old setup is mis-behaving, causing it to use up too much CPU trying to fix itself.
I've also had a lot of problems after installing Sierra OS on my early 2011 McBook Pro. This machine has performed faultlessly up until installation of Sierra OS. Now it gets hot and fans often run constantly. Why?
I had no problems at all up until now.
I ran the hardware diagnostics and the results indicated all should be fine. The system won't let me roll back my OS to an El Capitan (which was working just great). In desperation I booked an appointment with the local service center here in Singapore, they confirmed my hardware was in good shape and only solution was to re-install the version of the OS that was installed when the machine was new. Worse still, the data backed up using Time Machine would not be restored.
Apple seems to have made a mess of this one. I know others with similar issues with same generation of MacBook Pro.
