BlizzardBrowser Helper

BlizzardBrowser Helper is not a separately updatable application — it is a helper component of the Blizzard launcher. To ensure this helper runs natively on Apple Silicon Macs, you need to update the parent Blizzard launcher application itself to its latest native build. Open the Blizzard launcher, check for available updates via its menu, and install any available version. If your launcher is already current and the helper is still reporting as Intel-only under Rosetta, verify that you are running the native Apple Silicon version of the main Blizzard launcher (not the Intel build). The Blizzard launcher itself has shipped native Apple Silicon support for some time. You can confirm you have the native build by checking System Information: open the Blizzard launcher application, hold Option, and choose About Blizzard Launcher — if the Architecture field shows "Apple Silicon" or "arm64", you have the native version. If you see "Intel" listed there, download the latest Blizzard launcher directly from blizzard.com to get the native build.
