I recently got Mojave. Could somebody tell me whether it's possible to disable the use of the "com.apple.quarantine" extended attribute, for all apps that I have now or will ever download in the future? Thanks!

If I understood your question clearly, here is the solution that you can use to disable it completely.

  1. Open Terminal
  2. Type following command

    sudo defaults write com.apple.LaunchServices LSQuarantine -bool NO
    
  3. After that, reboot, and you should be set.

If you want to disable quarantine for files already downloaded

  1. Open Terminal.
  2. Execute the following command:

    xattr -l /path/to/application/applicationName.app
    
  3. You will see output similar to:

To remove an extended attribute manually, type the following command in Terminal

   xattr -d com.apple.quarantine /path/to/application/applicationName.app

    @Tetsujin and Udhy - This command looks familiar from the last time I used OS X (El Capitan back in 2016!). Ironically, I've just realised that this isn't the massive issue that it first seemed to be, since I now have all apps that I need installed and not nagging me. But if/when I find the need to install another, I'll let you guys know if it does indeed work. However, Udhy can have the accepted answer rep for now :-) Tetsujin, thanks anyway for trying to help and for being "fastest gun in the west"...perhaps the fastest gun I've ever seen on a SE site! – Kenny83 Oct 21 at 17:56
  • Hmm...nope that command doesn't actually seem to have helped - just downloaded a new .pkg installer and still got the dialog, even after right-clicking as suggested by @Tetsujin :-( I guess I can live with the annoyance of the popup dialog now, since I will rarely download/install anything else on this Mac. Just wanted to warn future readers that another solution is necessary. – Kenny83 Oct 30 at 12:43

First run, instead of double-clicking, right click & select Open.

Done.

Alternatively, disable SIP & you get this option back, in Security & Privacy…

… though you still get some 'are you sure?' messages, you can just say 'OK'

After comments: You may also need to set this in Terminal

sudo defaults write /Library/Preferences/com.apple.security GKAutoRearm -bool NO

From Permanently allow apps downloaded from "anywhere"

  • Dude, I would seriously give you +1000 votes if I could. Will definitely accept this answer as soon as I'm able (in 6 minutes apparently lol). Thank you so much! – Kenny83 Oct 21 at 16:02
  • Actually it seems as though disabling SIP on Mojave doesn't actually bring back that "anywhere" option...I've disabled it, restarted and still can't allow from anywhere :-( – Kenny83 Oct 21 at 16:31
  • hmmm… maybe I also did this… apple.stackexchange.com/a/198123/85275 - adding to answer – Tetsujin Oct 21 at 16:35
  • OK will give that a go...thanks again :-) – Kenny83 Oct 21 at 16:55
  • Wish you luck - let us know how it goes. The pic, btw, was from my own Mojave Mac, so I've obviously managed to do it at some point… I just don't remember quite how ;) – Tetsujin Oct 21 at 16:58
