Apple Addresses Hyper-Threading Issue With Logic 9.1.3

Apple today released Logic Pro 9.1.3 and Logic Express 9.1.3 to address an issue with Hyper-Threading.

This update delivers improved general stability and compatibility.

Issues addressed with 9.1.3 include:

- Resolves problems related to the support of Hyper-Threading

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. 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 updates weigh in at 193.01 MB (Logic Pro 9.1.3) and 139.68 (Logic Express 9.1.3) and require Mac OS X 10.5.8 or later.
