Can not update MacBook Pro (13-inch, Mid 2012 - i5 Intel) from 10.13.6 to 10.15
I have been trying upgrade my wife's MacBook Pro from 10.13.6 to 10.15 and can not get this done. The Software Update, just keeps presenting High Sierra which is already installed. I have booted in to Safe Boot mode and am continuing to sort it out. From the compatibility charts I have found this device should be good to go to 10.15. Is that not the case?
Any help is appreciated.
Thanks.
MacBook Pro 13″, macOS 10.13
