Within the terminal, for example, file name completion appears to be case-sensitive: 'app' will not expand to Applications.  But at the same time you can't create two files in the same directory with the same names but different cases.

I can do this either in the Finder or in the Terminal. They (seem to) appear as different files to the system. This seems to contradict your last assertion. Or is it that they only *look* as different but *are* actually the same file ?

This is how it was with my old laptop.
Be aware however, that if you use Adobe products, you will be much better off using a case-insensitive filesystem.
I know this for a fact with Adobe reader, which I grudgingly tried to use to fill out a grant application.
It simply would not work due to Reader trying to load libraries and plugins with the "incorrect" name.
In other words, they didn't expect that the application would be used on a case-sensitive filesystem, and so the name of the library and/or plugin doesn't match what they coded.
Looking through the strings in their application code, I noticed that they didn't even (at the time) have "house rules" on coding, i.e. they would capitalize function and variable names haphazardly.

It took quite a while before a support representative on the Adobe forums lambasted me with the suggestion that "Apple recommends that you do not use a case-sensitive file system" which is - of course - not true, or else why do they use case sensitivity in their server product?


I ended up using a Windows machine to fill out that grant proposal.
I was seething the entire time.

Not being aware of this has caused some headaches in the past.
