I'm very frustrated with the reduced battery life since I installed Mountain Lion on my mid-2012 Macbook Air. How can I reinstall Lion?
Please tell me how I can reinstall Lion on my mid-2012 Macbook Air. Following an install of ML 10.8.3, my battery life reduced from 7+ hours to barely 2.
I am not a technie person so please, tell me WHAT to do and HOW (step by step) to do it.
I am so sorry I installed the upgrade. Machine had been performing very well.
Thank you in advance for your help.
