Releases

Canister requires macOS 10.13 High Sierra or newer, and supports both Intel and Apple silicon.
Any version of Canister that is older than one year is unsupported and considered legacy. Chances are that a legacy version will work completely fine, but if you do run into trouble, please consider upgrading your license. For macOS 10.12, use Canister 22.3.5.
