Clear Battle.net Cache on Mac
Clearing the Battle.net cache means removing the cache and log items in your user Library, which the app rebuilds the next time it starts. Do this only when updates stall, login fails, or those folders keep growing, and leave your games and settings in place.

Battle.net cache folders you can clear
Battle.net has no separate cache folder. Its folders hold settings and your own data, so there is nothing to clear safely by hand.
What the Battle.net cache holds and when clearing helps
Specific to Battle.net
The cache and log files in your user Library hold temporary data that helps the app start quickly. Battle.net's data typically runs from 1 GB – 100 GB, so growing folders are the most common reason to act. Clearing the cache tends to help when updates hang at initializing, the app fails to log in, or the cache and log folders keep growing. The shared folder used by the Blizzard Agent holds download data for several Blizzard apps, so leave it alone unless you have removed all of them. Each game lives in its own folder, such as World of Warcraft, which holds your addons and settings, so it stays untouched.
What happens after you clear the Battle.net cache
Battle.net rebuilds the cache the next time you open it, so the first start after clearing will be slower than usual. Most game settings and progress are stored on Blizzard servers and tied to your account, so they should return once you sign in. You may be asked to sign in again, and your games remain licensed to your account. If something goes wrong, items in the Trash can be restored until the Trash is emptied, so wait before emptying it.
