64-bit Installer (about 451 MB) for macOS High Sierra, Mojave, Catalina, Big Sur and Monterey
32-bit Installer (about 99 MB) for earlier versions of macOS X
The 64-bit version of AQ for Mac has been notarized by Apple. This means that it has passed Apple's stringent anti-virus tests. macOS Catalina and later will not allow an app to run unless it has been notarized.
Still, some anti-virus apps report "false positives" when they scan the app, and this can cause problems during installation. If you have an anti-virus app, temporarily turn it off before downloading and installing AQ. Then run AQ once to make sure everything works (and if you are using Collaboration, to let the special components from Microsoft get installed). Once installed, and you see that AQ is running without issue, you can then turn your anti-virus app back on.
The 32-bit version, that will only run on versions of macOS X prior to Catalina, does not have these concerns.
Installation is pretty straight-forward. Click here for installation instructions, which includes a helpful tip.
