OSX's chief weirdness is that its GUI programs swap ':' and '/' when displaying filenames.

A remnant from the bad old days of MacOS <10, where : was the path separator, and / was a perfectly good character to use in filenames.

And indeed very frequently used for dates. There had to be _some_ way to deal with old file names in the new OS. From a UNIX point of view, one peculiarity of the Mac OS X native file system is that while case preserving for creation, it is case insensitive for lookup. On my Mac laptop, where everything is native, this actually works very pleasantly, although it does mean that "fn1 and fn2 are equivalent for lookup, whatever the state of the file system" and "fn1 and fn2 are equivalent for creation, whatever the state of the file system" are different propositions. On my Mac desktop, where _some_ directories are native and _some_ are NFS, it can get confusing. If memory serves me, Mac OS Classic recorded the script of each file name, so in a multidirectory path foo:bar:ugh:zoo each component might be byte encoded in a different script...
