If you are still using an Adobe Photoshop CS3 or CS4, you might have run into some funky Applescript errors. These errors sometimes pop-up as, “Error loading /Library/ScriptingAdditions/Adobe Unit Types.osax”, or “Can’t make 720 into type traditional points”, or something similar.
The fix for this is easy, and is provided straight from Adobe. The error comes from a conflict between the old 32-bit component and the newer 64-bit scripting environment of Mac OS X 10.6+ (Snow Leapard, Lion, and Mountain Lion).
There are three ways to fix the issue, but simplest is to download the updated file and install it into the “/Library/ScriptingAdditions” folder of your Mac, then restart your computer.
