Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I am using Golden Gate (macOS 27) for long sessions with Xcode 27.
I have never had problems going all day, but after long sessions, I run into trouble with copy/paste from Xcode to Cursor - both into document windows and the agent.. Cursor freezes, and sometimes Xcode, too. After it starts, restarting the apps is not enough. I have to reboot,

Steps to Reproduce

Work longer hours, copy/paste.

Expected Behavior

Copied text is used in Cursor.

Operating System

MacOS

Hey there!

Appreciate the report! Since macOS 27 is still in beta, we can’t guarantee compatibility until the official release, but it’s on our radar.

If you open up Activity Monitor once things start to freeze, do you see any frozen processes like pboard? Wonder if this is at the OS-layer rather than any specific app.
