KaleidaGraph and OS 10.7 (Lion):

You need to use v4.1 or later under OS 10.7. Version 4.1 is the first version that includes a universal version of the application. If you are running OS 10.7.2, you must use v4.1.3 of KaleidaGraph. This version fixes a crashing problem that was introduced by the update to 10.7.2.

There is a free v4.1.3 update available on our downloads page for users who have v4.x. If you have v3.6.x or earlier, you need to order an upgrade. (If you order a physical upgrade, you will get a CD that performs a complete installation. The electronic upgrade would need to see an earlier version on the computer.)

We are always looking for people with a good working knowledge of KaleidaGraph to become beta testers.

We need your input, your ideas, and your experience with KaleidaGraph to helps us improve the software, and increase the overall quality. This is your opportunity to access new features before these features are available to the public.Simply install and use the sofware as you normally would, and provide your feedback to us. > more
