When we posted on Friday that iTunes 10 had killed off old Automator workflows, it had all the hallmarks of a bug… and as it turns out, a but it is.
As it turns out, the problem is caused because Automator detects iTunes 10 as being a lower version number than iTunes 9, because Automator apparently sorts version numbers alphabetically instead of numerically.
As it turns out, the fix isn’t entirely onerous: simply open up the info.plist inside the packages of your non-functioning workflows and manually change the version number. If you absolutely can’t live without your iTunes Automator workflows until Apple managed to issue a Software Update, here’s your stop gap solution.
