Hey, crash code 5 on macOS usually means the renderer process crashed because it ran out of memory. A common trigger is long agent chats where a lot of edited files build up.
Here are a few things to try:
Start a new chat more often. Don’t keep one long-running chat. This has helped a few users. If you have a chat with a big list of changed files, close it and start fresh.
Check if your project is in an iCloud-synced folder (Desktop, Documents). If it is, move it to a local path like ~/dev.
Test without extensions:
cursor --disable-extensions
If the crashes stop, turn extensions back on one by one to find the one causing it.
Before the next crash, open Cmd+Shift+P → Developer: Open Process Explorer and check if the renderer process memory goes over 3 to 4 GB. A screenshot of this would be helpful.
Disable GPU acceleration to rule that out:
cursor --disable-gpu
If none of this helps, I’ll need:
Logs from Help > Open Logs Folder (the main.log file around the time of the crash)
A screenshot of Help > Toggle Developer Tools > Console right after the crash
Your list of installed extensions
