Hi all. I have a new-to-me Mac Mini A1283. Putting in a new SSD drive. My other machine is Windows 11. Using TransMac, I created a USB install stick of El Capitan.

The install routine forces a login with Apple ID credentials, however the login fails, my research indicates that the challenge protocols are now too new for this OS load.

Can anyone point me to an alternate load that does not try to validate logins, and allow the OS to install, hopefully future auth will work with an update ?

Thanks.

I thought there was always a way to skip registration, unless the USB stick you created is doing some type of internet recovery. Is this the only Mac you have?

yeah, just hit command-Q, and hit skip, or forgot password, where it will let you click set it up later
