APPLE HAS SPOKEN OUT about Consumer Reports' testing of the new MacBook Pro's battery life and has blamed an "obscure software bug" for the disparity in results.
Back in December, nonprofit reviews publication Consumer Reports refused to recommend Apple's newfangled MacBook Pro to customers after its tests showed the battery life on the machines would last anywhere from 19.5 hours to 3.75 hours, marking the first time that Apple's laptops have failed to earn the firm's seal of approval.
While Apple has kept quiet on the fiasco, the firm this week got in touch with the INQUIRER (I know, right?) to tell us that an "obscure" Safari bug specific to page caching was to blame for the inconsistent results and that a fix was now rolling out.
An Apple spokesperson said: "We appreciate the opportunity to work with Consumer Reports over the holidays to understand their battery test results.
"We learned that when testing battery life on Mac notebooks, Consumer Reports uses a hidden Safari setting for developing web sites which turns off the browser cache. This is not a setting used by customers and does not reflect real-world usage.
"Their use of this developer setting also triggered an obscure and intermittent bug reloading icons which created inconsistent results in their lab. After we asked Consumer Reports to run the same test using normal user settings, they told us their MacBook Pro systems consistently delivered the expected battery life.
"We have also fixed the bug uncovered in this test. This is the best pro notebook we've ever made, we respect Consumer Reports and we're glad they decided to revisit their findings on the MacBook Pro."
The fix for the Safari bug is currently only available to those who sign up for the Apple Beta Software program, but it will be a part of a wider software update available in a few weeks.
Consumer Reports says it's re-running its battery tests after downloading the software fix and will give the MacBook Pros a recommended rating if the problem is resolved.
While Apple's fix likely will keep Consumer Reports happy, early adopters of the new MacBook Pro have also been moaning about the laptop's "lacklustre" battery life. Following these early complaints, Apple addressed the issue by er, getting rid of the 'time remaining' indicator
