On Thursday, Apple released a pair of updates aimed at its pro users — an EFI firmware update for the 2010 Mac Pros, and a pair of software updates for Logic and its baby brother, Logic Express.

MacRumors is reporting that Apple released Mac Pro EFI Firmware Update 1.5 on Thursday for the company’s 2010 model Mac Pro desktops. The firmware requires Mac OS X 10.6.4 and is a mere 1.96MB download.

According to Apple, the update is recommended for all models of Mac Pro released in mid-2010, and specifically targets two areas. The first resolves an issue that prevented the firmware password prompt from being displayed, while the second squashes an issue that prevented the Boot Picker from being presented if Ethernet is connected to a network without DHCP.

Also related to the newer Mac Pro models, Apple released Firmware Restoration CD 1.9, a 22.5MB download which incorporates the same updated firmware but allows a user to clear up any potential problems that may have occurred from an interrupted or unsuccessful firmware update.

Apple was also busy on the software update front, releasing Logic Pro 9.1.3 and Logic Express 9.1.3, which specifically addresses an issue with Hyper-Threading as well as the always-helpful “improved general stability and compatibility.”

“Under Logic 9.1.3’s audio preferences, users can specify the number of audio rendering threads the software will open at any one time,” MacRumors explains. “While the option is set to ‘automatic’ by default and the maximum number of available threads is determined by the number of processor cores and support for Hyper-Threading on the user’s computer, the setting allows users to manually adjust the number of threads to best fit their workflow.”

The Logic Pro update weighs in at 193.01MB, while its smaller sibling is only 139.68MB; both require Mac OS X 10.5.8 or later.
