Recently I tried to factory reset my Macbook Air(Mid 2012 model). In order to do that
1) I booted into Recovery mode with Command + R.
2) Then navigated to Disk utility and Erased "Macintosh HD".
3) Then I restarted the Mac and booted into Recovery mode again(Command + R). Now Clicked on Reinstall macOS X.
4) It asked me to log in with Apple Id, I logged in with my Apple Id.(Before reseting the device is running El-Capitan and logged in with my friends Apple Id).
5) After logging in, It shown error like "This Item is Temporarily unavailable".
6) I tried to Install with Internet Recovery Mode(Command + Option + R). But not able to enter Internet recovery mode. Also created a bootable USB drive and tried to install macOS High Sierra. Tried to open boot options by holding Option(alt) key while starting the mac. But still Boot option was not available. enter code here
7) I really ran out of options, So I followed this procedure.(https://www.siliconsquad.com/how-to-fix-macbook-error-this-item-is-temporarily-unavailable/) This procedure is simply making a bootable USB drive and restoring it to Macintosh HD.
8) Then I tried to boot again, Got Prohibitory symbol.
9) Then tried to boot into recovery mode, but unable to boot into recovery or to OS X.
- Now, I'm have no other option to fix my mac.
Please advice and share your ideas to fix this. I'm in desperate need to fix this.
Note: I tried all the above with External USB Keyboard as well.
