Apple's new firmware update, released yesterday, appears to greatly reduce the annoying whine experienced by some MacBook Pro owners. The update was said to address several Boot Camp startup and wake-from sleep issues on its Intel-based Macs. One MacNN reader reports having to run QuietMBP -- a third-party application that made small changes to the way his MacBook Pro ran to reduce the whining noise -- prior to the firmware update. Meanwhile, another MacNN reader reports that his new MacBook Pro doesn't need the firmware update or a third-party software application to quiet his notebook, saying that the whine was never present in the later model.
