Here are a few suggestions that may help with your MacBook Pro overheating after updating to Ventura 13.5:
- Check Activity Monitor to see if any apps are using a lot of CPU resources. Quit any unnecessary or resource-intensive apps.
- Make sure your Mac is not sitting on a soft surface like a bed or couch that could block airflow. Use a hard, flat surface.
- Clean out any dust buildup from the cooling fans using compressed air. Dust can obstruct airflow and cause overheating.
- Reset the SMC (System Management Controller). This can help manage thermals. To reset SMC, shut down your Mac, press and hold the left Shift, Control, and Option keys and the power button for 10 seconds, then release and turn back on.
- Check if the overheating happens only during certain tasks. If it seems tied to a particular app, that app may need an update to be fully compatible with Ventura.
- Update to the latest version of Ventura if further updates have been released since 13.5. Later updates may provide fixes.
- Try reducing CPU load. Lower screen brightness, quit other apps, pause resource-intensive tasks like video streaming. Give the CPU less to do.
- If overheating persists, consider rolling back to your previously installed macOS version to see if that resolves it while a fix for Ventura is developed.
Let me know if the overheating continues after trying some of these suggestions. Overheating can sometimes point to a hardware issue, but software tweaks may help manage it.
