Some users Blade And Soul Gold in Apple

Some users Blade And Soul Gold in Apple's forums reported potential fixes, includingrepairing disk permissions or access control lists, disabling orreinstalling Dropbox, or resetting GateKeeper to allow apps toinstall from any source. These fixes didn't workfor all users, but together, they could be asign of a problem somewhere between Mountain Lion's securitysystems -- like sandboxing and file quarantine -- and the filesystem. Ourown testingrevealedsimilar (and significant) drops in battery runtime after installingMountain Lion. In previous tests, we were able to regularly achievejust over 8 hours of use by relying solely on our Retina MacBookPro's integrated Intel HD4000 GPU. Performing the same "real-world"test using the same software applications and usage pattern, wenever got the Retina MacBook Pro to run for more than a few minutespast 5 hours after a full charge.

Our test method isn't strictly scientific, of course, but weperformed it several times and got similar results each time. Iused the machine repeatedly for my daily workload, with Safari,Chrome, Twitter, iChat, Colloquy, TextEdit, Photoshop, Skitch,Mail, and Outlook running, as well as a few background processeslike Dropbox and gfxCardStatus. WiFi was turned on, the machinewaslocated in the same office as my Airport Extreme basestation, and Bluetooth was turned off. Screen brightness was set tohalf (8/16 "pips" or "dots" on the brightness indicator) as inprevious testing. During testing, I periodically launched Activity Monitor togauge CPU use. Typically, the quad-core processor wasn't taxedbeyond 5 percent capacity, except for occasional 10-20 percentspikes when loading webpages, reading or writing files, or otheractivities.
