iMac updates fix graphics, Thunderbolt
Apple last night posted four important updates for 2011 iMacs and various MacBook Pro models. The most critical is Mac OS X 10.6.7 Update for iMac (early 2011) 1.0, a 382.56MB file that targets numerous problems. The patch should for instance improve graphics stability, and the performance of both 3D rendering and FaceTime. Some bugs eliminated include ones with Back to My Mac, the Mac App Store and transferring files to SMB servers.
The code moreover improves external display compatibility and Thunderbolt device support. Serving a similar purpose is iMac EFI Update 1.6, which addresses issues with Thunderbolt stability and performance. The EFI fix requires that the v10.6.7 iMac update already be installed.
For MacBook Pros Apple has put out MacBook Pro Software Update 1.4 and MacBook Pro EFI Update 2.1. The former deals with graphics, display support, 3D performance and Thunderbolt compatibility. The EFI release is directed at graphics, Thunderbolt, and using Turbo Mode in Boot Camp.
