MacBook Pro 2010 Model - Yosemite Video Lagging Performance Fix
MacBook Pro 2010 Model upgraded to Yosemite. Show how to make some performance improvements which will in most cases fix Video lagging issues that occur from the upgrade.
There are other services that will run on your machine after upgrading will do background updates and that will slow your machine down.
Of high concern is Photo Agent.
But app store updates is the main one that I have found to slow down things down. I will post a solution (if I find one) for Photo Agent as soon as find it.
Apart from this I can say they have done a great job with Mac OSX Yosemite.
