It took longer than we had hoped to rewrite Prism Mac for the Cocoa system which lets us create a Universal Binary so it can run on Intel chips. If you are a Mac fanatic, you know what all that means. If you aren't, you only have to know that we went to lots of extra effort to make sure Prism 5 will work great with the latest Macs.

Early reports from beta testers are great. There are some bugs to fix, and a few features to finish. But releasing within a few months won't be a problem.

Thanks for your patience. It will be worth it.

Email me (hmotulsky@graphpad.com) if you have Prism 4 Mac, and want to beta test a preliminary Prism 5 Mac.
