Shut down your Mac, turn it on while holding down Command+R. Your Mac will boot into the recovery partition. If you’re using an older Mac (from 2010 or earlier), there’s a chance that you can’t use Recovery Mode. On those devices, hold “Option” while turning your computer on, then select the recovery partition instead. Just did a clean install of Snow Leopard 10.6.8 on an older Mac Mini in our family Apple Mac mini Core 2 Duo 1.83 Specs Mid-2007 ( MB138LL/A - Macmini2,1 - A1176 - 2108 ( Macmini2,1). I cannot install anything later than Snow Leopard on that (I'm pretty sure).
