How to Uninstall Xcode

October 3, 2008

A friend in San Francisco, Rodney Aiglstorfer, was recently jumping through hoops to get Xcode to cooperate with his iPhone. There’s nothing more aggravating than having your application running within the simulator and getting stuck downloading to a device.

At one point in the process he opted to remove the Xcode developer tools and start the configuration from the beginning. Which leads to the tip: should you ever find the need to remove Xcode, run the following from within a terminal window to make it happen:

sudo <Xcode>/Library/uninstall-devtools --mode=all

<Xcode> is the directory where the tools are installed. For typical installations the full path is /Developer/Library/uninstall-devtools

Easy enough, just make sure this is what you really intend to do as once it’s gone, it’s gone.


Thanks, this worked for me.

Thanks, too bad Mac can’t have help as simple as this listed on their support page or in the uninstall instructions that come with the software!

Brilliant. I was having trouble installing the latest iPhone SDK till I got rid of last Xcode install. Apple support said they were unable to replicate the issue!

Thanks! I actually got my hard drive down to 0KB free. (Actually, it says “Zero KB” at that point) Cleaning off Xcode was perfect, and couldn’t have been easier.

Well well, that was easy. Thanks so much!

the documentation, about removing xcode is in the Developer folder as pdf file. There you can find exactly this command line ;-)

by mongole on Aug 12, 2009 at 1:53 am. Reply #


The command line can be accessed with the Terminal Application.

I have the same problem as jackson; after a 10-hour download, it’s now saying “the following disk images failed to mount”… I’m trying to install XCode 3.1.2. Suggestions?

Thanks =) I need to get rid of Xcode in order to install iPhone Dev (that also includes xcode)

by gregmora on Nov 15, 2009 at 10:30 pm. Reply #

For me with XCode from Mac OS X 10.4 CD pack, this is the one to call:
sudo /Developer/Tools/ –mode-all

IMPORTANT: If you are going to install a previous version of the
Developer Tools, be sure to restart the machine after installing.

when i paste
sudo /Developer/Library/uninstall-devtools –mode=all
into a terminal window, it gives me this: “WARNING: Improper use of the sudo command could lead to data loss or the deletion of important system files. Please double-check your
typing when using sudo. Type “man sudo” for more information.”

then asks me for a password, but when i try to type, nothing happens- any ideas? I’m using 10.5.8 on a G5

by Erik on Feb 11, 2010 at 5:11 pm. Reply #

Hi Erik,

If you type the system/admin password, that should start the uninstall process.

by john on Feb 11, 2010 at 5:13 pm. Reply #

thanks, John- that worked- nothing visible happened when i typed, but it accepted the password and uninstalled xcode

by Erik on Feb 11, 2010 at 5:43 pm. Reply #

I tried this (on 10.6.2) and got the following error message:

ERROR: Can’t locate uninstaller script /Library/Developer/3.0/uninstall-devtools
ERROR: Can’t locate uninstaller script /Library/Developer/Shared/uninstall-devtools
Can’t determine system version.

Any suggestions?

I feel necessity to thank you also, just before i use this command, because I know it will work. You are the Chuck Norris of xcode.

This works but I have multiple installations of XCode (various beta’s along the way). How do I remove specific installations and leave the latest?

I downloaded the xcode 3.2.3 because I was start learning C on the Mac. The problem was that the book I was using used xcode 3.1 and I’m a beginner so I got confused when it wanted to use the standard tool from the command line utlility since that format isn’t available in the 3.2.3
So I copy and pasted that line into the terminal and from what I assume, it got rid of xcode cause I couldn’t find it. I didn’t restart the computer and just reinstalled the xcode 3.2.3 and nothing changed only this time when I tried to get rid of it the same before, it said that there is no such file or directory

what should I do??

The basic concept is to locate the uninstall file in the developer folder. Use “sudo” then “the uninstall file location” then add ” –mode=all”

When I type:

sudo /Library/uninstall-devtools –mode=all

in the terminal window I get the following response:

-bash: Xcode: No such file or directory

The problem I’ve been having is that the iPhone simulator will open then cease to respond to the point where I have to force quit the application. I figure the best way to resolve this problem is to uninstall the entire developer folder and then reinstall it. I’ve tried just reinstalling it and the installation fails each time.

Any advice, tips or even wild suggestions are VERY much appreciated. So far the three different apple support representatives I’ve spoken with haven’t been able to give me an answer. Apparently there is no documentation of this problem. So glad I was chosen to be the pioneer.

Thanks for listening to my rant.

Okay so I managed to solve the uninstall problem. It was simply a matter of taking into account that the xcode application was in my developer folder.

However, the second problem still stands. After I downloaded Xcode and iOS SDK 4.1 it told me the installation failed. When I went to go check the developer folder it had in fact installed. Then I opened Xcode to find the same problem with the iPhone simulator. When I would try to run it, it would simply stop responding and I would have to force quit it.

ANY advice is welcome. Thanks in advance.

Nice info I knew I’d seen this before and upon looking inside the developer library folder there is a script in there, which runs the following:

sudo /Developer/Library/uninstall-devtools

Thanks for this though – had me looking.

i tried to install Xcode twice, and both times it failed. so, i thought i should uninstall and then try to reinstall. when i tried, i got the following:

twolove:~ jovo$ sudo /Library/Developer/Shared/uninstall-devtools –mode-all
Unknown option: mode-all
Can’t determine system version.
twolove:~ jovo$

any thoughts?

by JoVo on Feb 11, 2011 at 4:16 am. Reply #

i get “no such file or directory” when putting this into terminal … any ideas?

JoVo you are clearly using wrong syntax, its –mode=all
It works like a charm

JoVo: It’s two dashes, not one. So “–mode” not “-mode”.

by JoVo on Mar 17, 2011 at 4:31 am. Reply #

Thanks. I have run this now several times, apparently successfully. However I still keep getting Xcode coming up in the possible software updates dialogue. Is this just simply going to always happen? I am not convinced everything has been removed from my HD

sudo /Developer/Library/uninstall-developer-folder
worked best for me. get a completely clean slate.

by Subwa Dio on Apr 12, 2011 at 4:51 pm. Reply #

Subwa Dio:

That does not uninstall all of the tools, only what’s in ‘/Developer’.

In fact ‘uninstall-developer-folder’ is invoked as part of ‘uninstall-devtools –mode=all’. (Read the scripts and see for yourself.)

Thanks for the tip. It freed up quite a bit of space on this drive space constrained MBAir. All that appears to be left under Developer is some documentation folders. If I wanted to reinstall, would reinstalling Lion reinstall devtools?

On my Mac, I’m running 10.7.2 and the correct command is: sudo /Xcode3.1.4/Library/uninstall-devtools. (All One Line)

To find it, I went to the Finder, selected my computer, choose Macintosh HD and navigated to the Xcode3.1.4 folder. From there, inside the Library/ directory, I saw the uninstall script. I double clicked it to run and it said I needed to use the ‘sudo’ command like you have above. I retried it with the sudo command and I’m uninstalling as we speak.

by Nashville Web Design on Nov 1, 2011 at 10:24 am. Reply #

I did the ‘find’ command listed above it was /Library/Developer/3.2/uninstall-devtools etc…

I have had Xcode 3.2 on my machine for a while. I’m trying to install it and all the other Dev stuff. None of this works. I don’t seem to have the unintall-devtools script on my machine. Can I get it from somewhere? Any other ideas.

Hey , I see it worked for everybody … but not for me ..
i copied the line into the terminal but its says that there is no such directory ? can you help me ?
i just got my mac so i dont know much about it

by j.p on Jan 5, 2012 at 1:14 am. Reply #

JP, when it says , you have to replace that with the path in which you installed Xcode. As it says the line below that, that is usually Developer. So try this code: sudo /Developer/Library/uninstall-devtools –mode=all

I am running 10.7.3. Xcode 3.0 came installed in /Developer/Library. I recently tried to install Xcode 4.3 from the app store. It installed in /Applications. Now, I try to install MacPorts, which installs successfully. When I try to run it, I get the following message:

Error: The installed version of Xcode (3.0) is too old to use on the installed OS version. Version 4.1 or later is recommended on Mac OS X 10.7.

The problem is that it is looking in the /Developer/Library for Xcode and finds the older version. I have tried to uninstall Xcode 3.0 with

sudo /Developer/Library/uninstall-devtools –mode=all

and I get the following error:

Can’t determine system version.
Can’t determine system version.
Can’t determine system version.

Can anyone help? I have been struggling with this for months now. Thanks in advance!
