So, I followed Foxlets guide to installing Mojave into my 2009 MacBook Pro as an experiment. However, the OS ran slow and various features were buggy. Therefore I proceeded to install a cop of macOS High Sierra via USB with no luck. I've also attempted to install High Sierra directly onto my MBP's SSD, with no luck. I always get the prohibitory symbol (gray circle with a slash) regardless of install method. The only way i have been able to bypass this is to use an old Snow Leopard disc which eventually reboots automatically and returns me to zero. Lastly, I cannot even enter the macOS utility screen.
When I HAVE been able to get to an install screen the installation of High Sierra tends to fail 2 minutes from completion.
I'm guessing there's some bios level setting that needs to be changed...if that's even possible.
I've searched the forum and no one else seems to be having this problem. My guess is i need to get into terminal somehow to flip some switches.
