Doug:

In case it isn’t crystal clear: scripts written for iTunes will not work on macOS 10.15 and later. Since the iTunes application isn’t available on the new OS, scripts that target it will fail. So, almost every script on the site will need to be re-written to work with the macOS Music and/or Apple TV apps that replace iTunes in macOS 10.15.

To help users keep track of what scripts for which operating system have been updated and when, I’ve posted Doug’s Check For All Updates. It’s an applet that will survey your computer for all the scripts you have installed from dougscripts.com and generate a report listing which have been updated.

If you are a user of Doug’s excellent scripts written for iTunes, download and run this.
