The operation can’t be completed because the disk is full.
I'm trying to move files from an external hard drive to my iMac's HD. It tells me "The operation can’t be completed because the disk is full."
I'm running Catalina 10.15.5
According it appears that I have 90GB free. I've tried moving a single small file and it won't let me. I have also tested and the external can copy to my macbook pro just fine running the same OS version.
iMac 21.5″ 4K, macOS 10.15
