According to a recent review on Macworld.com, Apple’s 17″ 2.33 GHz MacBook Pro laptop, which shipped this November, performs on par with the similarly-equipped 15″ model, yet falls short in collective iPhoto tests due to a bug within Mac OS X 10.4.8 discovered via a collaboration between Macworld Lab staff and Apple.

The tests, which demonstrated the expected results for trials within programs such as Photoshop, Cinema 4D, Compressor, iMovie, iTunes and Unreal Tournament, proved nearly identical for the 15″ and 17″ MacBook Pro models. The iPhoto tests proved far more relevant, as the 17″ model took 2.5 times as long to import 100 photos from the hard drive into the iPhoto Library and even lagged behind a 1.67 GHz model.
Puzzled, the Macworld Lab staff borrowed an identical 17″ MacBook Pro model from Apple and found the same iPhoto discrepancy. Swapping the hard drive between the 15″ MacBook Pro and the 17″ model proved that the 17″ unit had sped up considerably, but was still 11 seconds behind its 15″ cousin. Apple and Macworld swapped test photo files and in using Apple’s, the problem had disappeared. Upon further investigation, it was discovered that Apple had removed the ColorSync profile in their images, which made all the difference.
From Apple’s end, the staff removed the ColorSync profiles from the Macworld lab’s test images (a script for this entitled “Remove profile from image” can be found in the /Library/Scripts folder).
The change made all the difference and the 17″ MacBook Pro’s benchmark time went from nearly three minutes to a single minute once the script had been run. Both Apple’s and Macworld’s test systems had been running Mac OS X 10.4.8 and Apple has promised to look into the bug.
A full review of the 17″ 2.33 GHz MacBook Pro is forthcoming from Macworld.
