Update for 15- and 17-inch mid 2010 models
Apple has released an EFI firmware update for recent 15- and 17-inch MacBook Pro models. Version 1.9 provides a bug fix for an issue that sometimes caused systems to freeze during startup or occasionally stall during normal operation. The EFI download also improves compatibility with number of external displays.
The firmware update is recommended for all 15- and 17-inch MacBook Pros launched in the middle of the year. [dowonload - 2.16MB]
