I had Epson driver issues changing from PS CS3 to CS5. Also going up to Mavericks…… I don’t know which printer you are using. With 10.10.2 my Epson driver still has some issues with custom paper sizes. I over come them by putting the custom paper sizes in LR4. Then they are available in PS CS5. For me, when I really need clean work, I have 10.8.x on a separate HDD and can print without issues. I wonder sometimes why I even update my OS’s. Cheers David B. Miller, Pharm.

I am contemplating buying the latest Mac tower, which I am guessing would require the latest OS and the Cloud version of PhotoShop, etc. Are there any issues regarding file conversions?

My typical workflow in PS starts with RGB which I quickly convert to Lab for most editing. I then convert to cmyk for output, either for my inkjet printers or for offset printing. What I am concerned about is any variations behind the scenes from my current system which is CS3 and OS10.6.8. Is there anything I need to be aware of, any "new and improved" features that could screw me up?
