I would like to explore your last option. I did exactly what you posted in your screen shot but I'm missing something. jaybass
What you likely did was left the circled box checked, and that resulted in a keychain entry like the one in my screenshot. Deletion of that entry would accomplish your purpose.
At any rate, you're about to create a
sparse disk image.
1. To create a stock sized image, use
this format.
2. To create a custom sized image, use
this format.
3.
Final step.
Note that I created a minimum sized image in step 2 just as an example; yours can be any stock or custom size between 10.5 MB and 500MB, as you see fit.
I think this will finally set you straight.
Edit: At this point you've probably got a bunch of passwords in your keychain that can be trashed...for disk images that have been trashed.
