High CPU Usage / Melting Macbook

Bug Reports
1

Describe the Bug

My Macbook gets really hot and then I check Activity Monitor and it shows Cursor chewing through 400-600% CPU. Then I look in “Process Explorer” and it shows the IDE window just casually nuking my battery with not a lot of other information.

It happens multiple times per day.

Steps to Reproduce

Use Cursor.

Expected Behavior

Reasonable CPU usage.

Operating System

MacOS

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, have you also tried booting in safe mode to check this? If not, try booting with this command in the terminal: cursor --disable-extensions
