The newest version of Mac OS X, Mountain Lion, is reportedly causing users to experience diminished battery life.
Apple has stepped-in following a litany of complaints on its support forums from MacBook users and the publishing of a number of damning independent web-polls over the weekend.
Visible battery drain
MacWorld quotes on user on the support forum who said: ""I can visibly see the battery draining. In fact, when I first started writing this post my battery was at 96 pe cent and now, three sentences later, without doing anything else, and without having any other applications running, my battery life is at 91 per cent!"
Apple has now begun following up with affected users by sending them logging software and asking them to fill in email questionnaires.
You may recall similar users having similar issues with the previous OS X Lion launch last year.
