@imumesh18 Thank you for this change, and sorry for the awfully slow reply.

I think we should do something like this.

I was trying to test your branch out, but I was unable to get the new dialog to show.

I have set up my macOS settings so that iTerm is not allowed permission to open the Documents folder:

I then built a new version of zed (via cargo run zed).

I then tried to open the file with cargo run -p cli -- --zed ./target/debug/zed ~/Documents/desktop.ini

I see the error message on the command line:

error opening "/Users/conrad/Documents/desktop.ini": error opening "/Users/conrad/Documents/desktop.ini": Operation not permitted (os error 1)

but the UI is just blank:

I'm not sure if this is because I'm on macOS Tahoe, or because other recent changes to file loading are conflicting in a subtle way (e.g. #36764).

Do you have any ideas?

Hey @ConradIrwin let me test this again and see if Something has changed in zed or macos tahoe. I tested this with macos sequoia so not sure why it's not working. Will update you once I find something.

Closing for now to keep my backlog clean; but I am happy to try and get something like this merged
