Lion Compatibility of Checkout 3
Read on at The Checkout Blog
A Lion compatible version of Checkout is available from this link. Please note that this version is not yet compatible with Leopard and Snow Leopard. If you are running 10.5.8 or 10.6.8, please download Checkout from this link.
We will be releasing a version of Checkout that is compatible with 10.5.8, 10.6.8, and 10.7 in the near future. When this update is available, you will automatically be notified if you have selected the option to Check for software updates online (found in Manager > General > This Mac tab). If you do not have this option enabled, you can manually check by selecting Check for Updates which is located under the Checkout menu.
As is our policy, older versions of Checkout (i.e. versions 1 and 2) are not being tested, as they are no longer supported.
