Moving Photos from iMac to Walgreen's

Hey there!

To do that, you'll need to export the photos. This Apple Support article should help with that: Export photos, videos, slideshows, and memories in Photos on Mac - Apple Support.

Aside: If you ever take photos into Walgreens on a flash drive (rather than uploading them online), this might be useful.

--------------------

When you copy files from a drive using a Mac filesystem, to one using a FAT filesystem (like a USB flash drive), the Finder has a habit of creating little metadata "turds". You copy over PHOTO1.JPG and PHOTO2.JPG, but what the Finder puts on the drive is

PHOTO1.JPG
PHOTO2.JPG
._PHOTO1.JPG            <--- This is NOT a .JPG file but systems other than a Mac may think it is
._PHOTO2.JPG            <--- This is NOT a .JPG file but systems other than a Mac may think it is

I don't know if the ._ metadata files will confuse the Walgreens photo kiosk, but I have seen them confuse other devices like digital picture frames and TVs.

So, once you prepare your USB flash drive or memory card, you may want to

• Go into Terminal
• Type dot_clean -m and a trailing space (without pressing RETURN)
• Drag and drop the USB drive's icon from the Desktop to the Terminal window (to get the Mac to type in the right command-line name for you)
• Press RETURN to issue the command
• Immediately eject the USB flash drive from the Finder, before the Finder gets the idea to write more of the ._ files.
