Always the good corporate citizen -- well, maybe not always -- Apple has finally fessed up to both the MacBook discoloration and MacBook Pro whining issues that have been plaguing customers since the notebooks were released, and has agreed to fix the problems free of charge. We already knew that the company was sneaking new logic boards into Pro models that had been sent in for unrelated repairs, but now the "high-pitched buzzing sound," as it's technically known, has been officially acknowledged in a support page on the Apple website. An inquiry by DailyTech revealed that affected notebooks fall under the standard one-year limited warranty -- meaning that all MacBook Pros are covered -- and that the solution involves replacing either just the fan or both the fan and the logic board. The discolorations, meanwhile, have not yet been publicly recognized, but AppleInsider is reporting that a recent company bulletin intended for retail and service partners indicates that white, 13-inch MacBooks in a specific serial number range will indeed be eligible for a new top case and corresponding screen bezel -- assuming that approved cleaning solutions have been proven ineffective. Overall, not a bad resolution; sure the admissions could have come sooner, but instead of blaming the discoloration on dirty customers, attributing the whining to tinnitus sufferers, and calling it a day, Apple came through in the end and took the responsible course of action.
