Loading and watching prime video on my iMac
My computer (iMac, %K, retina, mid 2015 opens up prime but won't play any movies or shows. Tried to download;oad th app but it wants OS 11.4; really? I think it means 10.14. I manually upgraded from El-Capitan to Sierra (highest compatible with machine) but still looking for 11.4
Anybody have any suggestions on how to load an app to watch? I could not find anything in the app store and afraid to load outside apps
iMac 27″, macOS 10.13
