It’s about a day since Apple released the latest version of OS X, Yosemite.
Some can’t resist upgrading their Mac as soon as possible, others are far more cautious not wanting to create potential system instabilities.
There’s a helpful page on the Apple site showing compatiblily information.
Have you upgraded and if so how are you finding it, or are you waiting? Please vote and feel free to leave comments about OS X Yosemite upgrade experiences.
