Hi, guys --

The lack of case sensitivity in HFS used to be one of my very few
moans about the OS/X operating system. When I bought Tiger, I was
delighted to see Journalling and Case sensitivity options in HFS.

I installed Tiger, restored my home directory, and then started
to reinstall my apps. Adobe CS seems to install perfectly well
on a case sensitive HFS+ filesystem, but Photoshop CS wont start.

I did some digging around, and found a crash log, along the lines of :

====
Library not loaded: @executable_path/../Frameworks/AdobeBIB.framework/Versions/A/AdobeBIB
====

The issue was that the path is ..../Versions/a/AdobeBIB (lower case A,
not upper case.) Making symbolic links for the paths so that the
file can be found seems to advance me to yet another 'missing' file.

I think I therefore need to bite the dust and turn off case sensitivity.
Can I do this without having to reinstall ? I was hoping to find
some options in a file, like the fstab on many other unices, but
haven't come across any yet. Playing with the 'Disk Utility'
application options suggests that I will in fact need to reinstall.

Anyone able to tell me otherwise ? Can I make a case sensitive HFS
filesystem (that the system boots from) case insensitive ?

Actually, the HFS has always been case insensitive: I used to run a Tenon
BSD UNIX, and it had no problem putting files that only differed in case
in the same HFS directories. In reality, only various Finder functions
enforced case insensitivity. When the Finder discovers files identical
under case change only, it would complain.

Otherwise, I made a UFS install, and it works just fine. BSD UFS has a lot
of duplicate directories, making it safer against hard-disk crashes. I do
not know if Apple UFS has that.

Apparently, case sensitiviy is not a simple switch like journalling. The
only relevant reference I've been able to find to it so far is in the
newfs_hfs man page, suggesting that you would indeed have to wipe the
volume.

If you wanted to keep case sensitivity, I suppose you could run
Photoshop from a different volume (if available) or perhaps even a disk
image until Adobe fixes this -- which could take a long time.

Thanks for confirming; it's the answer I was expecting, but not the one
I preferred. ;-)

I'm guessing there would be a performance hit to run it from an
image.. and I also don't think Adobe will be likely to fix this
annoyance in a timely manner.

Applications shouldn't significantly care which filesystem they're
being installed onto (the installer wont even complete if you're
using UFS).

Thanks for replying.

Well, this case looks less like a deliberate decision by Adobe regarding
file system compatibility than just plain sloppiness in coding that was
previously masked by the file system.

This should have been: The HFS has always been case sensitive. Whether it
looks as case insensitive or not, depends not on the filesystem, but on
the functions used to maintain and look for files.

I agree: It is hard that Adobe would not knowing about it. I have noticed
they putting their files in places which differs from the Mac OS X
official file places only in case, in the case of their PDF Reader. One
might wonder why. The program is made for Mac OS X, not Mac OS 9, the
latter which always makes filenames look case insensitive.

I have also noticed a funny thing: I have an UFS and a HFS hard disk. A
UNIX program, Flex, uses files in the same directory which differ only in
case. If I backup this installation from UFS to HFS, but under Mac OS X, I
get an errror about these two files. So there are some functions under Mac
OS 10.3.9 that regard files identical if they differ only in case.
