The previous version is 1.23.10.12409. I and others cannot update the game to the latest version that was released about 24 hours ago. The app attempts to update and then sends a BLZBNTAGT00001389 error.
I’ve tried on Sonoma 14.4.1 on x86, and on Sequoia 15.1.1 on M1. Neither of them work, both of them error in exactly the same way. Frankly, it seems that the latest build is just broken on Mac for both platforms. Nothing I’ve tried seems to work in terms of fixing the issue. The log files indicate that the error occurred but there’s no useful information.
edit: Looks like totally purging Bnet and BW, removing all files and settings, and then reinstalling from scratch, fixes the problem.
