Battle.net installer wont start at all - M2, macOS 15.2

Unable to run the installer

steps taken:

  • Download mac installer
  • unzip Battle.net-Setup.app
  • Run file (on first attempt it asked me to install Rosetta and of course I did)
  • Nothing happens, app icon opens in dock but nothing else

I am using a Macbook Air M2 with Sequoia 15.2. Fresh factory reset with no other apps installed (asides from default Mac apps). I had Battle net installed before I performed the factory reset but I had so much old junk taking up space I wanted a clean start, now I cant install Battle net again.

I have also tried running from terminal but to no avail, I have checked firewall and permissions but firewall is switched off and there are no permissions that should be blocking the installer.

The only troubleshooting information I can find is from the activity monitor and it just says Not responding. I can also see what I think is a stack trace in the activity monitor but it doesn’t seem useful, just a bunch of AppRelocation directories

Im also having the same issue on a brand new M3 MacBook Air. checked firewall settings, set an explicit allow connections for battle.net and I’m a full administrator on my new machine. Is there anything else left to try?

Brand new M4 Mac mini - tried to install Battle net after setting it up and getting BLZBNTAGT00000840 error.
Reset the Mac and tried again - same issue.

I have the same issue on a new M4 max in germany.

Exact same issue for me. Contacted Blizzard but they just referred me to the most generic Troubleshooting page that didn’t help.

Same error here! Can’t find a fix anywhere.

I am having the same issue BLZBNTAGT00000840 error on my 2017 MacBook has anyone found a fix? Or is this a bug on blizzards end

I’ve seen it reported for Mac OS, Windows and Linux installs on official forums and subreddits. Seems like an issue a lot of people are facing at the moment.

Same BLZBNTAGT00000840 issue on my MacBook Air M3 Sequoia 15.2. Can Blizzard support provide a response if this is being looked at?
