Apple unveiled a number of firmware upgrades aimed at addressing several hardware problems experienced by owners of newly-introduced MacBooks, including the MacBook, MacBook Pro and MacBook Air.
The firmware updates were designed to improve stability of the new laptops introduced in October, Apple explained in a note.
“This update improves the stability of MacBook computers and addresses issues with sleep-wake, USB and device compatibility.”
The update also includes a firmware upgrade of the System Management Controller (SMC) chip used by the MagSafe Power Adapter.
Earlier this month, Gizmodo and others reported users of new MacBooks were having trouble with MacBook Pros exiting sleep mode unexpectedly or freezing when coming out of sleep mode.
The firmware updates, available through Software Update, are not needed by MacBooks released prior to October.
