Mac OS Big Sur - Dialog box not responding to mouse clicks

I have noticed that dialog boxes which open up for File Open or File Save As functionality in various applications do not respond to mouse clicks. I can close the dialog box by pressing on the "escape" key and can run default (highlighted) action by pressing the "enter" key. However, mouse clicks do not work. Has anyone faced this issue and is there a solution? I am using 2018 MacBook Pro 13 inch with Retina display.

I've figured out a way to resolve this on my machine (the System Preferences thing is the real bugaboo!): removing your `com.apple.systempreferences.plist` preferences file.


The step-by-step:


  1. Close System Preferences
  2. Go to Finder and select your user/home folder.
  3. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.
  4. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.
  5. Select Library.
  6. Then go to Preferences/com.apple.systempreferences.plist.
  7. Move the .plist to your desktop.


Restart the computer, open the System Preferences, and test. If it works okay, delete the plist from the desktop -- you won't need it anymore. If it didn't work, well, that sucks. Return the file from your desktop to the place you got it from, overwriting the newer one, then restart.


Hope that helps; let us know if it does!


Kind regards,

Erwin

I am also experiencing this issue on Big Sur - both the noted file dialog and System Preferences issues. If I restart, things are once again clickable but that is a super annoying workaround. However, I do think I found a workaround for the System Preferences issue. In System Preferences, make sure you are on the screen with items you need to be able to change (i.e. Bluetooth or General), minimize System Preferences, then reopen it from the Dock. Things on the screen you were on when you minimized should now be clickable.

Actually, it turns out that resize solution sometimes worked. it wasn't a complete solution.


My problem was specifically with gitk, a tool that is packaged with the Home Brew git-gui package.


You might find some relief by deleting ~/.config/git/gitk if that file exists.


I also ended up editing /usr/bin/local/gitk to point at the OSX version of wish (/usr/bin/wish) instead of the HomeBrew version.

Dear Missy5937


Sorry to tell you but you completely missed the point. In our cases, the trackpad and/or mouse still work perfectly, can select different windows, click everywhere and so on.

The problem lies in pop-up windows (as in "save as" for a document) as well most of the System Preferences windows* are irresponsive to the clicks. Those two types of windows refuse any input. The Tab key is often our only resort to interact with such windows.


For most "save as" and similar dialog boxes, resizing them (each one, each time) somehow allows mouse input again, which is a good but annoying workaround to this problem. However, as the System Preferences windows cannot be resized, many systems cannot be reached. The "lock changes" button is by the way not the cause as this one cannot be clicked either.



*only System preferences responding to the mouse clicks in my case :

  • Mission control
  • Spotlight
  • Trackpad
  • Displays


This makes it difficult to update my mac, as, well, the Software Update menu is not in the above list...


By the way, I am running BigSur 15.5.2 on an M1 chip macbook pro 13 inch.


In the hope this helps the support in identifying the bug,
