iMac internal card reader
Hi,
I have a weird problem with the internal card reader of my 27-inch iMac 2017. Normally I import my photographs with Capture One Pro.
Since a couple of weeks when I plug in a SD-card the import window of C1P appears, showing all the images like it should do, but when I start to import the images it only imports a small number of photo's from the card. After 5, 20 or 25 images it stops and I get an error message. After each failed attempt I can't eject the card either. I have to force quit the card.
On other occasions it works just fine and imports all photographs.
To rule out the SD-card I tried several cards, both importing from C1P and directly to Mac OS Finder. Same problem. Sometimes it works, more often it doesn't, not card dependent.
To rule out a possible Capture One Pro failure, I tried copying images from the card to the Mac OS finder. Same problem, sometimes it works, sometimes it fails after a couple of images.
Finally I dug out an old USB external card readers by Hama, and every card I plug in just works fine, time after time. So I guess it's safe to say that it is the internal card reader that is causing the problem.
Any suggestions on how to fix this without having to send in the iMac?
Cheers,
Ivan
