Upgrade macOS Catalina on my Thinkpad E450

In the last few years, I learned a lot about how to install macOS on pc. So this week I try to upgrade macOS Catalina on Thinkpad E450. Because this computer has good compatibility with the macOS Mojave. So I installed macOS Mojave to it. And Then double click the MacOS Catalina installer package. I find this method is very simple to upgrade macOS to higher OS version. It’s a better choice than a new installation. In this way, only need my clover EFI. So look at some snapshots. I will give the download address of my EFI later.
