Applications installed with brew cask install won't launch for other users

Question

I have two users accounts on my Mac, one for personal use and one for work use. I use Homebrew to install most of my applications.

However, whatever GUI application I install using brew cask install <app>, it won't launch for the other user. Every time I try to open such an app with the other user, I get an error like:

I noticed that the application files are installed owned by the installer (in this case the user work):

$ ls -l /Applications/
 ...
drwxr-xr-x@  3 root    wheel   96 Feb 11 20:13 Siri.app/
drwxr-xr-x@  3 work    staff   96 Feb  6 19:52 Spotify.app/

How can I get the apps to launch also for other users on the system?

Answer 1

The issue seems to be some directories in the app folders missing the execute bit. You can check permissions using for example:

find /Applications/Spotify.app/ -type d -exec ls -ld {} \;

Directories should have permissions drwxr-xr-x@ but some were drwxr--r--@.

The following command will change all directories to have the execute permission present:

sudo find /Applications/Spotify.app/ -type d -exec chmod og+x {} \;

The same needs to be run for all apps having this issue.
