Mac Pro Firmware Update Released, Fixes Power Nap and USB Device Recognition Issues
Apple recently released an SMC firmware update for the redesigned Mac Pro that enhances Power Nap fan control and fixes an issue that caused low-speed USB devices to remain undetected on system startup. The Mac Pro SMC Firmware Update 2.0 tweaks system control settings to allow certain Power Nap processes to run without spooling up the fans. That being said, the exact Power Nap activities covered in the updated settings weren’t detailed in the release notes.
For those of you who don’t already know, Power Nap is an energy-saving feature that allows Macs to keep up to date even while sleeping. For example, with Power Nap enabled, Mail is able to collect new messages in the background without waking the Mac from sleep.
The recent update also fixes a rare issue in which low-speed USB devices weren’t being detected at boot.
Apple’s firmware update comes two months after the company released an EFI update which addressed various bugs in December before the computer shipped out to customers. Recommended for all late-2013 Mac Pro models, the Mac Pro SMC Firmware Update 2.0 comes in at 544KB and can be downloaded via Apple’s Support Downloads webpage or via Software Update.
