So the vast majority of our millions of players are installing, updating and playing without issue. In fact a good portion of the few posts made here in the last 24 hours were from the same player. That doesn’t suggest a large scale issue and doesn’t help address your specific issue to assume there is some sort of large scale service issue.
The BB8 error is a generic error, it means the Agent program in the Blizzard Desktop Application was unable to complete a task it was performing and it doesn’t know why.
Typical causes are connection issues to the patch service, data corruption of downloaded data, software conflicts preventing needed data from being applied to the app or game client or a permission issue of some sort.
The solutions typically come down to, cleaning up the connection, clearing/replacing potentially bad data, removing software or permission conflicts.
So to properly resolve this for you, we need to go through troubleshooting of the local system, app client and network.
First make sure you have all updates for the Mac via software center. You may need to restart and check multiple times to get them all.
Then let’s go ahead and clean up the local network:
Try doing an extended power cycle on your system. Turn off all devices including the modem. Wait 30 minutes, turn on the modem, wait 5 minutes, turn on any network devices, wait 2 minutes, turn on your computer and try the game.
You can try switching your DNS settings to use a free public DNS servers instead of your ISPs Servers:
We do not have individual steps for specific modems or routers so if you need assistance accessing or updating the devices, contact the device maker/provider.
Sometimes firewall or routing software/hardware will have some advanced settings to prioritize and manage types of network traffic. Normally that is not an issue but we have seen situations where it can intefere with the delivery of the data for our games/voice chat.
Let’s try turning off these features:
RoG (ASUS Routers Only)
Security firewalls (Some ISP provided modems)
Not all devices will have these options and the steps for turning these functions off will be different depending on the make/model/software version of the devices and programs involved. If necessary look at the documentation for your security and routing products to find out how to turn these options off.
In some cases there is a corrupt or misconfigured setting within the router or modem. We cannot say what that might be offhand but the easiest way to resolve these conflicts would be to factory reset the router and/or modem.
You may need to look up your specific model for the steps on how to do this and in some rare cases you may need to have this done by the ISP. Feel free to reach out to them for assistance if necessary.

It is important to get all the preference and plist files relating to blizzard as that can definitely cause issues if that data was corrupted. A simple reinstall does not clear this data.
Finally we will want to look at potential permission issues, either due to software conflicts or OS permission issues.
