Apple has released updates for its latest range of laptops with separate downloads now available for the unibody MacBook, MacBook Pro and for the MacBook Air.

The MacBook Pro 15-inch SMC Firmware Update 1.2, MacBook SMC Firmware Update 1.2, and MacBook Air SMC Firmware Update 1.1 all address the same issues.

Apple says the update improves the sensing and accuracy of the MagSafe Power Adapter indicator light, and the battery charge indicator lights.

MacBook Pro EFI Firmware Update 1.6, MacBook Air EFI Firmware Update 1.1, and MacBook EFI Firmware Update 1.3 all fix several issues to improve the stability of the MacBooks.

Owners can wait for their machine's software update to kick in, or download the software direct from Apple's support site.
