which the document's contents will be set and maintained by the user
(i.e. I can't use XCode to generate the schema at compile time and use a

Running Leopard on a Mac Pro. Photoshop won't start--claims that a file
is locked. Well it isn't the PS app, and it isn't an image file that I'm
trying to open. So?
I'd like to search down the applications file directory, and see if

I know that OS X 10.5 is very good at cross-platform support but I'm
trying to support or refute some claims by software publishers.
Given a bunch of applications (proper GUI app, not command-line) how do I
tell whether they're PPC, Intel, Universal, 64-bit, ARM (!), etc. ?  I

I have a C/C++ program that I've ported from Windows to Mac OS X 10.4.  It is
built using a traditional makefile and g++.  While in development, I'm just

regardless of setting in IB in version 3.0; yuck, or maybe there's some
other way to have the color distinction as in 2.x?
Xcode also shows unified coloring but not my news client Thunderbird, so

   I have downloaded Apple's demo project Abstract Tree which uses
the Core Data system and XCode 3.0 (under 10.5.1) and can compile and
debug this on one machine, a G4 Powerbook but when I try to debug on
my Dual Core G4 desk top (also under 10.5.1 and XCode 3.0) it fails to

I'm stuck in another area of my app where I'm not making much progress,
so I wanted to step out of it for a bit and work on how to bundle my
application for a release.
I will have my app, a *.dylib, and a directory of example files to read

Question for anything that might have used Sparkle before ... I did not
find a sparkle forum anywhere's, so thought it might be ok to post

I have a big memory leak in a method which simply reads from a text
file and adds each line to an NSMutableArray as an NSString, and then
return the array to the caller.
I'm positive that the memory used by the array of strings is not freed
