The Xquartz project is an open-source effort to develop a version of the X.org X Window System that runs on Mac OS X. Together with supporting libraries and applications, it forms the X11.app that Apple has shipped with OS X since version 10.5. The updates available on this site are not official Apple releases. They are a convenient way for users to stay up to date with progress made in the open source community (in which Apple is participating). Official Apple releases will come from Apple (most likely through OS and Security Updates via Software Update). These updates will likely incorporate many of the changes made in our releases when and if Apple deems them appropriate.
i got this to go with GIMP, because for some reason the X11 that i thought was working, which has been there since i got my mac, wasn't working any longer for no reason. instead of complaining, i took the effort to find something and stumbled upon this, but at startup, i couldn't understand a thing. started GIMP, nothing happened. i would love if someone can tell me how to get GIMP to work with this, but at this moment, i'm not going to uninstall until i know for certain that it's not worth having.
Fewer bugs and more features than the standard X11 server that ships with OS X. If you compile Unix software via fink or macports, you want to install this.
It is installed as a separate program, instead of overwriting the X11 version that ships with OS X.
This program is only for geeks who like to compile Unix software from source on their computer. Fink and Macports are the easiest avenues of doing this. This software is not for the average user.
I don't understand the 1-star ratings. XQuartz is always less buggy than Apple's official X11 releases.
It bears mentioning that XQuartz _IS_ the official Apple X11 windowing server. It's just that Apple integrates updates to X11 very rarely in its OS X updates and releases. So, if you use any software that uses the xwindows system, or if you compile software that build depend on xwindows components, then you need to install XQuartz.
Confusing for newbies and non-programmers. Disabling or uninstalling it are non-trivial exercises; see http://xquartz.macosforge.org/trac/wiki/X11-UsersFAQ
If you don't know whether or not you need it, you don't need it. Most of the one-star reviews are from people who "gotta have" the latest and greatest of everything, don't know what they're doing, and come here to vent their frustration. If you've got Compulsive Update Syndrome, relax: Apple will eventually incorporate the changes into future OS updates, so you don't have to worry about being "left behind".
If you understand the difference between Terminal and an xterm, XQuartz is closer to the open source development versions of xorg-server, the environment for X windows, a Unix thing. I needed it for an X11 program (Wireshark) and it works well.
Today (2010-11-01) I see that CNet TechTracker says the current version 2.5.3 needs updating when it doesn't.
Since it continues to show up in CTT update alerts, you can 'Hide' or 'Skip' (until next update) and it won't bother you. I mention this because there are so many one-star reviews. You might have installed it for a program that needs X11 and therefore it shows up in the update alerts. For folks that need it, it is great. Most MacOS X users do not.
The standard X11.app shows a big problem with Sun Global Desktop: no keyboard hit gets through. This XQuartz version solves that rather serious issue - it makes Sun's virtual desktop solution actually usable on a Mac.
I'm on Leopard, which means XQuartz must be re-installed after a system/securiy update. One star subtracted for that.
@Noznavde. Maybe you can help explain why this shows up on everyones' updater. Is this the open source component of X11 that all Mac users who installed this feature will see? My first thought was that this had something to do with CNET's Tech Tracker. I guess it's possible for both of these ideas to be true though. Thanks for your time
Not one thing at all, except the advertising promises, but they don';t pan out.
It does not work at all, despite the recommedations form TechTracker, Version Tracker, and/or other sources. The system owns it, even tho i've changed the permissions/privs, so that i could trash it, it's blocked me from being able to do so.
Think twice before installing it please. Read what you can find so you understand what it will/won't do. i'm stuck with it being owned by the 'system' ~ i can't launch it, can't delete it. Hope others aren't as disillusioned as i. Guess i've always trusted being able to do 'trials' or use demos to help me decide if an app is my cuppa tea or not. Made a mistake here.... that's for sure.
