I was gifted a mid 2010 MacBook Pro. It is in great condition and the previous owner did a couple of upgrades including two 4 GB DDR3 memory cards and a 1TB SSD Hybrid drive. There is literally nothing on this computer as far as files, photos, music, all of the things that usually take up hard drive space and memory. Only the operating system -- High Sierra 10.13.6 and any apps that came along with that. Of the 1Tb there is 998.9 of unused space, lol! I was hoping to upgrade to Mojave. Mostly because I have an autistic teen and wanted to be able to download some apps for him to use. When I read the physical requirements for Mojave it seems like my MB pro has it. I have searched countless websites and some say mid 2010 some say mid 2012 are the requirements. IF it is mid 2010 then I have everything one needs to upgrade to Mojave so I don't understand why I can't. I'm here because I tried following the steps to do it on this webpage and it didn't work. I tried saving to an external drive. There must be a way!
