Latter for mid-2010 15-inch model only
Apple issued two support updates today, the first another bugfix update for the Apple TV, the second a model-specific update for the mid-2010 15-inch MacBook Pro to fix issues relating to intermittent freezing of video. The 4.4.2 release of the Apple TV firmware is meant to consolidate fixes first offered in a troubled 4.4.1 update that was subsequently pulled and then re-instated due to a flaw in the update itself. Apple advises users to reset the Apple TV before applying the new update.
Both the 4.4.1 and 4.4.2 updates are said to fix sleep/wake issues and remote control problems, as well as provide subtitle support with Netflix and smooth out Airplay mirroring issues. If users do not reset their Apple TV units before applying the 4.4.2 update, the update itself will do this, requiring users to re-apply the update. Reports so far say that doing this appears to finally clear up the updating issues, which have been ongoing for most of the month.
The MacBook Pro Video Update 1.0 is intended specifically for the version called the "mid-2010" 15-inch MacBook Pro, which was released on April 13th of that year and were the first to incorporate the i5 and i7 processors. According to a technote, the problem affects machines produced between April 2010 and February 2011.
If the machine is running Lion (Mac OS X 10.7.2), the problem can be resolved through the update. If the machine is running Snow Leopard (10.6.x), users must find a nearby Apple retail store or independent Apple Authorized Service Provider and take the machine in for servicing. The technician will perform a software diagnostic test to determine if the model meets requirements for the fix. Affected computers can be repaired for up to two years from the date of (registered) purchase even if they are out of warranty.
