myatmo works up from v4.2.0 on all Macs with an Apple M1 chip with macOS 11 (or newer) and can be downloaded from the Mac App Store. Up from v4.7.4, myatmo no longer supports Apple Silicon chips due to technical reasons.

If myatmo is not displayed in the 'iPhone & iPad Apps' section of the Mac App Store with the release of v4.2.0, please try again later - it will take a while for the App Store to be updated worldwide and for myatmo for compatible Macs indicates.
