Hi, I would appreciate some help to resolve this issue installing Catalina on a iMac (Late 2015, 3Tb fusion, macOS Mojave 10.14.6)
![Macos catalina not installing Macos catalina not installing](/uploads/1/3/4/4/134487492/327067512.jpg)
I downloaded Catalina from the app store, it begins the installation process, but get the following error when it is about to restart
'An Error Occurred while preparing the installation. Try running this application again'.
Tried restarting a number of times, also checked the date in terminal (picked up from another post), same issue. Any suggestions appreciated.
Thanks
