I can't launch Brave on macOS Catalina

@baker00,
And Brave isn’t still getting blocked by your system?
Would you be willing to download and install our Brave Beta build to test and see if you get the same results?

I’ve tried the beta version in the past with the same results as the stable version, but I’ll try it again.

Tried Beta again. No luck, same result as before.

@baker00,
Okay, it seems I may have made an error in an earlier reply:

:point_up: I gave the wrong directory – can you try instead clearing the folder found at
~/Library/Application\ Support/BraveSoftware/?

This is the actual user data files that may be corrupted. Note that this will remove any user data you have associated with the browser but since you’ve already tried deleting and reinstalling I’m assuming you either have your data backed up or there isn’t anything particularly worth keeping.

Delete the Brave-Browser folder found in the path listed above, then try to launch Brave again.

If you get the same results, trash the entire BraveSoftware folder, the Brave.app file and reinstall. My bet is that it will work after deleting the Brave-Browser folder though :slight_smile:

Sorry, no luck. I have syncing set up with Brave browser on my 2014 Mac Mini. Could this possibly be a syncing issue?

@baker00,
Sorry for the late reply, I’m just returning from some time off.
Sync could be a factor, although if the Beta showed the same behavior I think it’s unlikely. Still worth a shot!

Try launching from the terminal using the --disable-brave-sync flag. Also, I’d recommend trying to launch with Hardware Acceleration disabled. You can also do this from the Terminal using the --disable-gpu flag.

I’m having the same problem. Here’s what I’m doing:

rm -rf /Users/alexander/Library/Application Support/BraveSoftware

/Applications/Brave\ Browser.app/Contents/MacOS/Brave\ Browser --disable-brave-sync --disable-gpu

And the error I’m getting:

@alexander_00001,
Why did you use the rm -rf command? Were you intentionally trying to clear your Brave data?

Try using the same command but only use one flag at a time and see if you get the same result.

I used the rm -rf command because you advised to delete that folder a few comments above.

I tried the same command twice with one flag at a time and the results are identical:

Instead of the method you’re using, can you try simply removing/trashing all Brave related files – including the .app file, then re-download/install the browser?

I already did that (deleted all Brave related folders, deleted the app itself, downloaded Brave from the official website). I also tried Brave Browser Nightly, it’s the exact same error I’ve posted above.

@alexander_00001,
Have you checked to make sure Brave isn’t being blocked by your system security prefs? Can you check System Preferences --> Security/Privacy --> Lock icon and see if Brave listed here?
