Hello folks. I am very satisfied with how Mavericks runs on my 15" 2012 Retina macbook with 8gb ram. But at the same time I want the extra stuff Yosemite offers. I am hesitant to upgrade because my machine only has 8gb of ram and I assume that it will page much more frequently than it currently does with Mavericks. So my question is simple. Should I go ahead and upgrade to Yosemite, or is 8gb ram not enough? My usage will be moderate. Not extreme, like running parallels or such, but it wont be just web browsing and word documents either. I will use photo and video editing programs and I dont want to see any beachballs... Will appreciate any feedback on this.
