First, what do you mean by #12 and #4?
Error message as follows:
At line 82 of file "Macintosh HD:Applications:Adobe Dreamweaver CS6:Configuration:Commands:CustomizeFavoritesClass.js": getDocumentDOM: Argument number 1 is invalid.
At line 252… (same as above)
OK, your link worked, I used #12, unhiding the Library folder worked, following the instructions for renaming Dreamweaver config and pref files also worked. Restarted Dreamweaver and errors and problem gone! Great advice. Thanks much.
I left an online thank you message, but again, #12 procedure worked. I am new to Mac, and previous versions of Dreamweaver on Windows 7 did not have this issue for me.
