When opening a file with cursor, it will be stuck or take a long time to load

Bug Reports

Describe the Bug

The specific manifestations are as follows:

  1. Almost every time a new file is opened by clicking on the file list, it takes a long time to load, approximately 5 to 10 seconds.
  2. When saving a file, if there are eslint and automatic format configurations, it will also be stuck for a long time.
    I tried:
  3. Restarting the computer, attempting to uninstall and clear the cursor data, and then reinstalling the cursor; but it didn’t solve the problem.
  4. Disabling all extensions and using the most basic configuration, but still had the same issue.
    Supplementary: I use the same Mac computer and VSCode, and I don’t have this problem.

Steps to Reproduce

At present, it can only be reproduced on my computer, and I’m not sure of the steps for reproduction either. It suddenly started to lag today.

Hey, can you check what is displayed when opening files in Process Explorer? Maybe some process is happening there.

btw, source ~/.zshrc takes a not short time, does cursor problem related to this?

Possibly, yes, the issue might also be related to zsh. What happens if you open the terminal in Cursor? Also, try changing the default shell to bash to check if the problem is related to that or something else.

change zsh to bash(i dont know why process name still has /bin/zsh, and has /bin/bash at sametime) & open the terminal in cursor also stuck for a while… :face_with_crossed_out_eyes:

and, even i disabled plugins such as eslint & prettier, it also takes few seconds to save file modification:

In contrast, vscode is extremely smooth.

This problem has been bothering me for two days…
Urgent need for help.Or should I consider reinstalling my computer? :face_with_crossed_out_eyes:

It seems there’s an issue with the terminal. Have you tried completely reinstalling Cursor? Here’s a guide on how to do it correctly:

I solved it, by reinstall MacOS completely.Maybe there is really something wrong with my system environment..
Anyway, thanks a lot for reply & help :smiley:
