Apple updated the EFI firmware for the Macbook, Macbook Pro, Macbook Air and iMac late yesterday. These updates all “fix compatibility issues” with their respective machines.
A firmware up date was also issued for the new aluminum keyboard, resolving an issue where a key could unexpectedly ‘stick’ and repeat characters. It also mends “other issues” as well.
Finally Apple released the the 3rd iPhone SDK Beta. The size of the Beta is down to 1.4 Mbs, and improves Microsoft Exchange support, and fixes some outstanding bugs.
You can get it right here.
