Hey, thanks for the report. Editor freezing during editing in version 2.2.20 on macOS is a known issue tied to one specific setting.
Cause: If you have this in your settings.json:
"workbench.editor.showTabs": "single"
It directly causes freezing during any AI file editing.
Fix:
- Open
Cmd+,(Settings) - Search:
workbench.editor.showTabs - Change from
”single"to”multiple"(or delete the line) - Reload
This should fix it completely. If it still freezes:
- Clear chat history:
~/Library/Application Support/Cursor/User/workspaceStorage - Disable hardware acceleration:
Cmd+Shift+P> “Preferences: Configure Runtime Arguments” >”disable-hardware-acceleration": true
The team knows about the single tab mode issue and is working on a fix.
