Save as Adobe PDF showing multiple instances under Print window > PDF
On Mac, when using the Print command in any application and then selecting PDF at the bottom of the window to export a PDF, multiple instances of Save as Adobe PDF will show up due to old versions of the application hanging around after version updates. One of my Macs had 9 and another Mac had 3 instances showing.
I tracked down that these live in a folder called PDF Services which is located:
Macintosh HD > Library > PDF Services
where you can remove the old ones or all if you’d like.
Would suggest Adobe clear these out during new installs.
