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.
