Mac OS X 10.10 Yosemite Compatibility

Checkout v4 has been tested on the new Mac OS X 10.10 (Yosemite) operating system and is compatible. There are two known display issues in the current version of Checkout (4.0.7) and Yosemite that will be addressed in a future update.

If you are planning to upgrade to 10.10 we suggest you upgrade to the latest version of Checkout and, of course, back up your Store.

Checkout versions older than v4 will not be officially supported or updated for 10.10. If installing Checkout for the first time, depending on your Security & Privacy settings in System Preferences you may receive a message "Checkout can't be opened because it is from an unidentified developer.”  

To open Checkout you will need to go to the Security & Privacy settings in System Preferences and choose Open Anyway.
