My USB 2.0 flash drives, when inserted in the USB slot, no longer show up on my iMac, running Sierra.
They used to, a year or two ago, but don’t now.
Can I do anything, or are the drives just useless now?
[I wanted to use them to transfer short videos to the PCs of people for whom Dropbox is too confusing. The people are over 90 y.o.]
thanks for any help!
