Intalling 10.13 on a Mid 2010 iMac
I have two Mid 2010 iMacs. One of them I am running 10.13.6. The other one's harddrive recently bit the dust. I decided to swap out the bad hard drive for a SSD. That was smooth and the OS defaulted to 10.6. I was able to get it up 10 10.8, but when I try to install 10.13 from a flash drive, it keeps erring out. I've searched here and online and tried a bunch of solutions, but can't seem to get anything to work. I am thinking that the installers have to contact Apple, and Apple has stopped that from happening. Any solution I am missing? Thanks.
P.S. I don't have a backup of the old system, but I do of the good system. I am wondering if I could try installing from that back up?
