Hey, this is a known issue with the extension host on macOS. It doesn’t initialize when you open a new window, so both source control and agents stop working. A few users have been hitting this since 3.0.x: Cursor last update freeze on macOS
A couple questions to narrow it down:
- What exact macOS version are you on? Apple menu > About This Mac
- Do you have any MCP servers set up? Cursor Settings > MCP
Also, try this:
- Launch Cursor from Terminal with
cursor --disable-extensionsto see if extensions are the cause - If it still happens, try clearing the cache. Delete
~/Library/Application Support/Cursor/Cacheand restart - Also check Console.app for Cursor crash reports. If you find any, paste them here
The team is aware of this issue. No timeline yet, but your report helps us prioritize.
Let me know how it goes.
