Yosemite Beta 5

Apple has released some Golden Master versions of Yosemite to Developers over the past few days. They also released Yosemite Beta 5 today. I installed it, not too much new except for one thing. Fast! It is very fast on my iMac 2012 with 16 GB of RAM. Keep in mind, I have very little software on this beta install, but still it really is fast. I like it!
