I bought an old mac mini (early 2009) at a flea market.
I removed the 1Go and replaced by 2Go to use Mavericks.
I tried installing the original OS X Mavericks but I need an Apple ID to install and I don't want one.
So I looked for custom OS X and I found Niresh. I downloaded Niresh Mavericks and created an USB install drive.
So I reboot the Mac Mini and press the Alt or Option key and select my USB.
But it can't boot and I had this kind of logo:
What's wrong? Can Niresh work on an original Mac Mini?
