In-Design CS3 on Mac

[dougmar74]

My In-Design CS3 dose not work after Mac OS update to 10.13.1 High Sierra even with the older Java installed as suggested.

CS3 is very old, and not written for or supported running under a brand-new operating system. 

This has been covered before in the forums:

Does ID CS3 work with High Sierra?

It won't work till you install InDesign CC2015/2017/2018.

Furthermore, the activation servers for CS3 have been retired. Your serial number would not work. You would have to follow the directions given in this link, but it's highly unlikely you could get it to work as pointed out above:

CS3 Activation-the solution!
