I have an old 2011 Macbook Pro and I am running InDesign (and other Adobe apps) CC 2015. It is chugging when I am using the apps. Apart from getting a new HHD or upgrading my laptop, I was hoping that a good temporary solution would be to create a lower limit to the memory used by the apps? Has anyone done this? If so, how did you do it and was it worth it?
That is not possible.
You can try the old versions of InDesign.
