As others have said, no problems.
I recently did a format and clean install of Yosemite. Its not something I have done since my windows days, but glad I did.
Kinda makes one re-evaluate software needs.
I'm slowly adding stuff and SVII was the latest.
I also learned something new. Bright monitors hurt my eyes. When lowering the brightness, I noticed the dE would rise a good bit. I used an intensity of 90
Found a check box that lets the color patches linger a bit longer. Brought my dE levels back down below 1.
This may not really matter,but I feel better about it.
