[Guide] Install Catalina on the Dell Optiplex 7010 and 9010 Desktop PC

[Panpanjiao]

I will put it in an old general case I already have. I will not buy the Dell OEM power switch since I don't have a good way to install it in the old case.

There aren't many options when using the stock power supply. If you can find one of these at a good price grab it.

Getting error "This copy of the install macOS Catalina application is damaged, and can not be used to install macOS"

If it is a new download of MacOS Catalina, then check your computer's date in bios

Also, replace the 2032 battery with a new one if you forgot to do it.

Catalina installed. Boot time with a SSD is longer when compared to my High Sierra with SSD. Also when booting with clover by default it boots from recovery. How can I change this?

Open your config.plist with Clover Configurator. Where it says Default Boot Volume either make it as shown below or type in the exact name of your SSD drive there. Also make sure debug is unchecked to get faster boot times.
