I am about to change my Mac osx from 10.6.8 to 10.10 Yosemite. I am currently using Dreamweaver CS5. I guess I have to upgrade to CS6 or similar.Is thata correct?
You could try it first. Some people have been successful using CS5 on Yosemite. Some people haven't.
You will need Java SE6 to run DW (not Java 8 which ships with Yosemite).
It might also be necessary to wipe your Preferences and reinstall CS5.
Thank you I will consider that.
