Your InDesign probably crashes because you are trying to use very old CS4 on a relatively new Mac OSX. Adobe and Apple are barely on speaking terms on a good day.
Indesign has a lot of features that I like as a printer. The color palette works a lot better than Illustrator, especially when applying swaps for colors. The multipage feature makes it easy to apply cut paths and crop marks to all the artwork in the doc, assuming the designer has followed certain conventions. There are a lot of different ways to do things in InDesign, and some of them would be the wrong ways. I swear I have one client who actively searches for devious ways to crash a rip or otherwise throw wrenches in the works.
It’s not the best software for projects if you are using a die-line for router cut graphics but in the grand scheme of things, we’ll deal with a die-line in InD over multipage docs in Illustrator. Illustrator multipage is NOT made for pagination purposes.
Also, I do large format print. InDesign uses a memory-conserving method of placing images that makes it very quick and easy to work with large images and transparency effects.
Illustrator tends to choke on placed images much over 500mb. Add any kinds of trans effects in Illustrator and, in some cases, you may as well go get coffee while it redraws.
You also don’t get the dreaded Illustrator error message “can’t move artwork off the artboard,” due to masked parts of images. Indesign will place containerized art as close to the edge as I want it. Sometimes I need to move stuff, or cut down the artboard size before printing. For example, if you put a postage stamp on a ledger art board, you really don’t want to be paying for the price of the ledger board. Multiply that in a printer using 16’ goods and you pay a lot of extra for wasted space. But that’s a whole other rant.
