Recently purchased an Apple - USB-C to SD Card Reader to import all my pictures from various SDHC cards. I connected the adapter with the SD card, but nothing happened. Then I got the message “The disk you inserted was not readable by this computer”. Have restarted the MacBook Pro (2019), which is connected via USB-C. The photos do not open automatically, and even when I open photos, there’s no option to import. Are SDHC not comparable with this card reader? I also
