Hello good night everyone from Colombia,
Beforehand, thank you very much for all the help you can give me.
I will express myself:
I have a Dell OptiPlex 9020 PC identified with the Service Tag: 9QL6942 with the following features: Intel Core i7 4770, 16 GB of RAM, 120 GB SSD; which I want to install MACOS Catalina. I have doubts if it can be installed on that PC but in case you can try to do it (with your help of course).
It is my knowledge that before doing the installation the BIOS must be configured, but because my PC is a pre-assembled device, I cannot find these options in the BIOS.
