Macbook Pro overheating


I have an overheating Macbook Pro (same goes for Macbook Air as well) and as far as I see the problem is caused by the Zwift application not providing the option to decrease CPU usage (i.e by frame rate?) in the game. Reducing resolution doesn’t solve this issue. There is an option for battery saving, which actually decreases frame rate on the backend afaik, but obviously applicable only when power is unplugged, thus if you work on battery, it works cooler and actually the fans stop. Else, fans blow at 100% and it feels like the notebook will explode any time :frowning: Needless to say CPU temps go well over 100 degrees celsius. :o

Soo, this is clearly a Zwift for Mac optimization issue, and not being resolved so far is a big disappointment if you ask my opinion.

If I were able to run Zwift while the macbook is powered, I would be able to continue using clamshell mode but now I cannot. (When lid is closed, if you unplug the laptop, secondary monitor is disabled. You need to open the lid.) And when unplugged, with the current battery health, I can ride about 2 hrs max, and the battery dies.



Yes, this is a problem, I have given up using Zwift on my MacBook Pro, which has an enhanced GPU, as the fan run continuously and the computer overheats. I don’t have any sense that there is any Zwift interest in sorting this. Disappointing.


Zwift please address the MacBook issues. Don’t want to overheat and destroy my MacBook Pro or have to buy more hardware.


This is still an issue, somehow?

I have an M1 Air and a maxed out 2021 i9 16" MBP.

The Air is unusable after a few minutes, as it loses connectivity. Maybe that’s kind of excusable, since it has no fans.

The MBP has enough processing and cooling to drive three 4k monitors and Gradle builds all day long, yet somehow it’s thermal throttling to 40% while only running Zwift at 720p on its built in display.

yes, this is a pretty major issue for me, too.

I found an application called appolice that allows me to throttle my CPU for a specific app ( in this case zwift) - I was able to go from 99-103degrees C to about 67-69C by limiting the CPU to 55% +_ , you will need to play around with your setup to see which limit works best

secondly I used fanny widget to monitor the temps and fan speed , while I made adjustments on apppolice- i let it run for 30min with the power plugged in. This helped me hone in on the best CPU limit for my setup

hope this helps and works for others

Amazing news!! I’ll try it out, thank you so much for sharing this.
