I’ve two previous MacBook Airs: one from 2011 and one other from 2015. The 2015 Air boots positive, whereas the 2011 provides me the flashing folder lacking system icon on boot. I attempted booting it into restoration mode, and it asks for a password, which I am as close to to 100% certain I’ve appropriately, however after I enter it and press return, the password area clears and nothing else occurs.
So I assumed I might use the 2015 Air to create a bootable USB drive with Excessive Sierra on it (the most recent OS the 2011 will boot, based on MacTracker). Plugging this into the 2015 Air whereas the Possibility secret’s held down appropriately provides me the selection as well from the inner or the USB drive.
Nevertheless, doing the very same factor on the 2011 Air provides me the ineffective password display screen. Not holding the choice key down (hoping that, failing to seek out an inner boot drive it will look robotically for an exterior one) brings up the flashing folder.
I am guessing maybe that making a boot USB from the 2015 will not essentially work on the 2011. Or possibly the 2011 is just a brick now. Is there something to my concept in regards to the 2015 not creating an accurate boot drive for the 2011? Is there something I can do to carry the 2011 again to life by putting in a brand new OS on it in some way?
