Can't update to Update 1.0
I just can't update to Update 1.0. My Mac freezes every time after I download the update from the App Store and try to install it. After a hard reset Yosemite tells me that the update wasn't installed and shows me a pop up message where I can click on Install. Then nothing happens.
With some luck the update reappears on the App Store and everything goes from the beginning, otherwise it just says No Updates Available and I can wait for it to reappear. Strangely the update appears in the Updates Installed section of the App Store, but I can ensure you that it isn't installed. The same goes for iTunes 11.2.2 as you can see from the picture below.
I did a clean install just last night after I thought that my installation was somehow corrupted. Since then I tried it 3 times now.
I'm using a Late 2013 27 inch iMac with a 3.5 GHz Core i7 CPU, 8GB 1600 MHz DDR3 RAM, a 2GB GeForce GTX 775M and a 512 GB Apple SSD.
@Mods: I'm not having the same issue as this guy. I already read this thread.
