"Can't install OSX el capitan, stuck on installation screen" için yanıtI’m (of course) the one poor sod out here that none of this date reseting is working for… Picked up a mid 2009 MacBook Pro 17”. It has the latest firmware on it. It came with El Capitan installed and I hadn’t realised it was a slightly older model that I couldn’t upgrade. I’ve tried everything imaginable to get this %#*@ thing back to El Capitan but nothing works.. I get this same infuriating message every time. I ‘m going to bin the bloody thing in a minute! I’ve tried dates between 2015 and 2018 nothing… same same same… I’ve run the installer from a bootable USB drive. set the time and date numerous times in terminal.. nothing works.
