Running Mavericks 10.9.5, iMac 12,1 21.5 Intel i5 2.7ghz 16gb.
I want to re-image the machine but it only boots with a Guest account. No Recovery partition and unknown admin password.
Using "Install OS X Mavericks" but need admin password. It does have a Boot Camp partition that has Windows 10 which I have admin rights. I want to get rid of everything but being guest on the Mac side without admin rights does me no good.
My last thought was to just take the 1 terabyte drive out and erase it from another Mac then re install Mavericks OS.
