Apple Events Bug?

I was disappointed to receive a couple of crash reports from users of newer scripts using pre-macOS 26 operating systems. As they put it, the scripts with the new “colored icons” seem to be the problematic ones. These are the most modern versions of the scripts and they have all been recently developed on macOS 26 Tahoe.

Most of these scripts haven’t added anything new but have just been updated to account for UI changes; earlier versions ran fine on earlier OSes. One Correspondent ran his crash report through ChatGPT which surmised that the issue was related to a failure in Apple Events: “The applet had an Apple Event in progress and macOS was trying to resume/finish processing that event when an internal CoreFoundation array became corrupted or contained an invalid pointer.” While my own thinking wasn’t that specific, something along those lines had occurred to me as well.

I don’t like to guess about these things, but my guess is that some version of macOS 26 introduced an issue that doesn’t fly so well in earlier macOS versions. I haven’t received any reports of errors or crashes from users of macOS Tahoe (or Golden Gate betas).

Be that as it may, if you are using a pre-macOS 26 operating system, download a new script and then find it crashes, you can try reverting to an earlier version of the script. Most modern scripts have a direct download link to a “Serviceable Antecedent” which is located in a script’s “INFO” section on its entry page.
