I´m having hard times with my MBAir (old model, only one usb port). If you could help I´d appreciate it. Thanks in advance!
Symptoms: The MBA doesn´t turn on. When I push the power button, the led light appears, the screen goes grey with the apple (as normal) and after 8-10 seconds, puff... it goes off.
Diagnosis (via Mac´s Genius Bar): The hardware is fine, the data is there, the OS X is corrupt
How to fix it: Reinstall the OS X
My main problem: I need to do the backup of the data (very important) and reinstalling the OS X deletes the internal HD completely
So, what I´ve been told:
1. Install the OS X on an external HD;
2. Power on the MBA, running the OS from the external HD;
3. Save the data;
4. Reinstall the OS X in the MBA
Seems easy, but it´s not:
Question 1. How do I install the OS X on an extHD, having 2 separate CDs, from a PC?
Question 2. Does it (the extHD) needs to be formatted?
Any further tips are extremely valuable! Thanks**
