I have a brand new iMac and I am brand new to Mac OS so I am sure the issue is me rather than the equipment.
The issue is I shoot in Raw, I use Lightroom classic
When I import I plug in my sd card and send it through the usb.
I let Lightroom tell what folder because I really don't know how Mac handles raw files. Lightroom sent it to "pictures" in a dated folder
I click import and all files import fine, but as soon as their done importing they become color bars and 1,4 pictures with all sorts of white diagonal lines through the rest of the picture.
I deleted the whole import and tried again, same thing.
I made my own folder on the desktop labeled it RAW and just downloaded the files directly from the SD card through USB and into the file I just created.
They download fine and when I open the file in the iMac app "Photos" they all appear fine (I guess photos has a raw converter?)
I then try import into Lightroom from MY file and then the files are broken again.
Whats going on here is it Lightroom.
Any and all help would be appreciated.
On edit; just tried a different sd card and have the same results.
