The Achilles’ Heel of the latest and greatest Nehalem-based Mac Pros seemed to be their trouble handling audio processing—even playing a song in iTunes reportedly caused overheating and sacked performance. Mac Pro Audio Update 1.0 offers sweet relief.

According to MacWorld, the new update, which rolled out last week, seems to help the matter both in terms of cooling temperatures and reclaiming processing power.
In a series of tests, they determined that installing the update resulted in a significantly quicker Aperture import and Compressor encoding with the machine simultaneously running iTunes—19% and 16% improvements, respectively. After the update, the Mac Pro’s CPU was also running 30 degrees cooler and sucking less power from the CPU and power supply.
The update is currently only for Snow Leopard machines, so Leopard users, who have also reported the problem, will have to wait a bit longer to get things sorted. [MacWorld]
