StickyBrain 3.x is not compatible with Intel based Mac's, including the Rosetta environment. StickyBrain 4.x on the other hand is a Universal Binary, which means it will run natively on both Intel and PowerPC Mac's. We do not have any plans to add Intel support to StickyBrain 3.x. If you want to run StickyBrain on an Intel Mac you will need to upgrade to SOHO Notes. For more information on upgrade pricing click here.
