How do you import photos from an SDHC card?
How do you import photos from an SDHC card? I plugged in the card and it created a file in Finder that I copied and dragged into Photos. I wiped the SDHC card and ejected it. When I tried to fool with the pictures I'd imported, a message said the originals were missing and these could not be opened, changed, modified, edited, cropped, forwarded. What did I miss? New to Catalina and to SDHC cards. Thank you all.
