Early adopters of any new hardware are always the ones who get burned the worst by hardware and software glitches, as we've seen over and over again. Some owners of the new 13-inch 2013 Retina MacBook Pros were finding that their keyboards and trackpads would occasionally become unresponsive, and after acknowledging the problem last week, Apple yesterday issued the MacBook Pro Retina EFI Update v1.3 to fix it. The previous, temporary workaround involved putting your computer to sleep and waking it back up, an inconvenient and potentially disruptive bandage.

Owners of the 15-inch 2013 Retina MacBook Pro shouldn't feel neglected just because their keyboards work properly—that laptop is also getting new firmware in the form of the MacBook Pro Retina EFI Update v1.2. This update applies specifically to high-end models with Nvidia's dedicated GeForce GT 750M GPU and "addresses an issue which, in rare cases, may limit the performance of the discrete graphics processor after a system wake or boot." If you have the lower-end version with the Intel-only GPU included, your laptop will still download and install the new firmware (as ours did), but it probably won't alter the laptop's performance.

Apple also issued a patch for Mail.app in OS X 10.9 yesterday, aimed specifically at bugs being experienced by Gmail users of the operating system's built-in mail client.
