I often use AirDrop to move photos from my iPhone to my Mac, and I'd like to automatically convert any HEIC photos to JPEG. I created this folder action in Automator, and it works when a photo is dragged into the Downloads folder but not when it has arrived via AirDrop. Is there a trick to getting folder actions to work with AirDropped files?
I needed to tweak this a little for me on Sonoma. I made the pause 10 seconds just in case I transfer dozens of files in bulk. And then instead of copying the files, I chose to duplicate the finder items because I wanted to convert them and put them in the same folder (in my case, "Downloads". Usually I'm uploading receipts or silly images for fun online so instead of having to send 3 MB per pic, I do a Scale Images down to 30% of the original size and that makes it around 200 kB usually for my images.
