I’m humming along using Adobe CS5.5 on my 2011 iMac 27” [with an updated SSD] on macOS 10.13.6 [High Sierra]. I know I’m running on fumes and luck, so one day somethings gonna give. I’m looking at options for a used, but newer iMac on which I can continue running CS5.5. Any suggestions since the new iMacs won’t run my CS5.5?
