Trying to downgrade from High Sierra to Lion

Hi all,

I'm trying to downgrade from High Sierra to the factory default for my 2011 Mac Mini (OS X Lion). After booting in Internet Recovery Mode, deleting the hard drive, I try to re-install OS X and it comes up as High Sierra (not Lion which came with the machine).

have tried multiple times with the same result. Please help!

Thank you

Mac mini, macOS 10.13

How can I downgrade my macOS? Hello all, I'm trying to setup a new-to-me mid 2012 MBP with Mojave. It came to me with a fresh install of Catalina. I quickly realized this machine cannot run Catalina. I also use iTunes and thus would like to move back to Mojave. After watching some videos and reading online it seemed simple enough. However I've hit an early snag. Just downloading Mojave the MBP jumped straight to trying to install it. Reading online I should have been prompted first and clicked "no." But I never got the prompt. It's now stuck trying to "install update." I've quit the program as well as fully shut down the machine. When I go back to download it appears to have already been downloaded as it jumps straight to trying to install again. But if I search the machine I don't see the Mojave OS anywhere. Any ideas?

Boot into Internet Recovery Mode using Command + Option + Shift + R which should boot to the oldest available macOS installer for your Mini. Most likely it will not be 10.7 Lion, but either 10.8 Mountain Lion or 10.9 Mavericks.
