Hello All,

I am very happy with My Mac Pro 4,1->5,1, I am using Martin Lo's opencore package, but every time I try to upgrade to a new version of the macOS, all fail, can not direct upgrade, I have to reinstall to a new SSD then clone it from the old Mac fo all app that I was installed, I saw some people can direct upgrade without any problem, anyone can give me an advice, Thank you!
 
For some guys it works better booting the createinstallmedia thumb drive / partition and do a reinstall with keeping the user data.
