Two updates are available for MacBook Pro owners: MacBook Pro Software Update 1.4, a 132.69MB download, and MacBook Pro EFI Update 2.1, a 3.06MB update. Both are available direct from Apple's website or via Software Update.
Update 1.4 is said to include fixes that improve graphics stability, address issues with external display support and 3D performance, and also improve Thunderbolt device support.
Meanwhile, EFI Update 2.1 includes fixes that resolve an issue with Turbo Mode in Boot Camp, and improves performance and stability for graphics and Thunderbolt. A user's power cord must be connected and plugged in to a working power source when applying this update, as it updates the EFI firmware on the MacBook Pro.
