A firmware update released in June should have resolved an incompatibility with new SATA hard drives released for Apple's professional notebooks, but, after months since the update, users still report compatibility issues with these drives. The constant appearance of the waiting cursor and recurring crashes are two of the many negative effects still reported by several customers.
Of course, many people are able to work without problems, but there are those who are even unable to reinstall the system through the DVD that comes with these machines, due to an incompatibility with the personalized hard disk. At Apple Retail Stores' Genius Bars, some customers are finding a solution to this problem, while others successfully reinstall the system using a Mac OS X 10.5.8 DVD through the procedure Archive & Install.
Both solution methods, however, are unpredictable and do not solve the cases of all affected customers. One of our readers, the Tiago, is aware of the problem with his MacBook Pro and made contact with Apple, who said he is working on a fix. According to his comment, it may still take a while.
