New Mac user need some info..

Oh, man... I'm not good with unix, but I can tell you this: X11 is a window manager that lets you use linux and unix apps that have been re-compiled the PowerPC chip in your Mac... translation.... lets you run linux and unix apps on your Mac... useful? Depends on if you really need a unix app of some sort. It's a few hundred megs.

iLife- the suite of applications by Apple designed for your digital iLife, including iTunes, iMovie, iPhoto, iDVD and GarageBand

However, now that I mentioned it, I'm not sure if you get the option to NOT install those during isntallation. I'm not sure. Each of the iApps is somewhere between 50 and 100 megs... so you're not necessarily saving that much space with those... except for iDVD and GarageBand, whcih are huge... a couple gigs or so, each.
 
X11 is a graphics layer that normally runs on top of UNIX to provide a graphical user interface for various graphical applications (browsers, productivity software, etc.). You'll find X11 on various UNIX-like platforms like Linux, all of the BSD variants, Solaris, AIX, etc....and even Mac OS X.

There are two aspects to the X Window System (X11): The X server and X clients.

The X server is what basically provides the graphical framework for various applications, window managers (fluxbox, FVWM, etc.), and desktop environments (KDE, GNOME, XFCE, etc.). If you were to run the X server by itself, all you would see is a gray background with a mouse pointer. Nothing else.

The X clients are those window managers, desktop environments, and various other applications that run on top of the X Windows System (X11). They use the X server system to provide the widgets, windows, and other things that make these desktop environments and applications useful to us.

The nice thing about having X11 in Mac OS X is that it adds a plethora of other applications normally found in the open source and UNIX world. However, it does mean that you would be running a graphical environment alongside Aqua (the native Mac OS X graphical environment) which may require more memory than if you were just running Aqua or X Windows on a UNIX machine.

The X Windows system also does have a lot of networking features which allow you to forward applications to another X11 system so that they can be run remotely.

I know I'm missing more things on X11, but that's the best I can muster. :p
 
I wouldn't throw out the BSD stuff. If you later wish to learn about the Unix foundation of OS X, you will want to have that installed. I don't think X11 is installed standard anyway. I think you have to get that off the third disc.

There's one thing you can try to fix your problem with Traktor, since their technical support was clueless. I won't guarantee this will work. I don't think you can mess anything up using this tip. But I won't guarantee that either.

Here it is: Go to www.versiontracker.com or www.macupdate.com and search for "renice" or "nice". A renice'ing program will increase the priority and thus processor cycles of an application relative to other running applications. So if you have, say, Traktor running and Safari and Word, and you set Traktor at a higher priority, the system will give it more processor time. This won't magically speed up your computer, but it may give Traktor the extra time it needs to work reliably.
