On a tangential note, there were reports about the Intel based MacBook Pro from earlier this year having CPU usage spikes and heating issues when charging from the left side port. For users with this problem, it was effectively “charge using the right side port”.
- threeseed 6y agoAs a MacBook Pro owner this is nonsense. It throttles badly and overheats no matter which side you charge on. Actually surprised it didn't get more attention. If you're downloading and charging at the same time then your computer is unusable.
- brailsafe 6y agoHmm, I'll check this out today. Ironically I was downloading XCode last night and the fans sped up for an hour.
- eyelidlessness 6y agoI definitely get more heat and throttling powering on the left side than the right, on my 2019 16”. There are quite a lot of people who have reported the same, for all models which have USB-c ports on both sides. If you’re not seeing a difference, it’s pretty likely your workload or some background process is still pushing the thermal limits of your machine.
- tgarv 6y agoHmm, I wouldn't say this is nonsense. I can consistently reproduce the issue by charging on the left side (making the computer completely unusable), and then switching to the right side and having it run perfectly fine. Since I started charging on the right side I've had zero issues with it.
