I'm on an iMac 2.7GHz i5, 16Gb RAM 1600MHz, mountain lion. I use regularly licenced CS6, especially photoshop, illustrator and acrobat pro.
I'd like to upgrade to mavericks, but frankly, on the web there are too much rumors that this or that won't work then... I use my imac to work, I'm a freelance web developer, so I cannot have problems on my machine. It must work.
So, is there any DEFINITE answer to this issue? Apart to definitely stop using adobe products (I'll do it..).
