What macOS do I need on my iMac 2011 to update my Photoshop CS5?
I want to buy new actions for my Photoshop CS5 but I cant because I don't have an updated version of my OS I believe. I have MacOS High Sierra for my 2011 iMac. I can't even upgrade my Google. Does it have to do with buying more space?
