My iMac Retina 5K mid 2015 model will not read my Ultra all in one digital card reader in any port. I bought a Ionn version of the same product and same issue. Is there a special digital card reader for the new iMac ?
My new iMac 5K model will not read my digital media reader in any port. I have the Ultra all in one model and the Ionn multi media memory card reader.
Is there a 'special' one I should be using?
Please assist
Thank you
iMac with Retina 5K display, OS X Yosemite (10.10.3)
