Close Window (Xcodes "Installation Alert") that has no kind of closing elements

Is there a tool with which I can click on a window and the tool will tell me which process that window belongs to ?

Explanation:

I was working in Xcode 3.2.3 for iPhone OS 4.0beta3. Wanted to install old Xcode (all old SDKs got removed with beta3).

Didn't want to waste time so I kept working in new Xcode for iPhone OS 4.0beta3 while downloading and then starting the installation of xcode 3.2.2 with iPhone SDK 3.2.

After sometime开发者_如何学JAVA there came this window:

"Installation Alert"

In order to continue installation, please close the following application:
Xcode

But by then I didn't want to interrupt my programming session as I was near a next milestone. Well, next day and after a Macbook standby I finally wanted to close the Xcode with SDK 4beta3 and finally install the old SDK. But the Installation Alert wouldn't disappear (even though Xcode was closed now). So I thought ok, then lets just stop and restart the Xcode Installation... So I went to the "Activity Monitor" and stopped the Xcode Installation. The Xcode Installation window got closed, but the "Installation Alert" is still there.

So how do you get rid of such a window ? It has no buttons, no menu in which to select a "close window".

Edit: Well a restart of course solves this problem. And I never faced this problem again.

He's right. Kill 'AlertAll' and that will allow you to proceed. Make sure iTunes is also killed.

Killing the ItunesHelper is the solution.

For those who don't remember how to do that:

1. Go to Utilities
2. Open Activity Monitor
3. Find the ItunesHelper in the list of running processes.
4. Click on the "Quit process" button on the upper left corner of the window.

"Same here... I am trying to install a 2gb xcode but that stupid window won't close>>> ANgRy"

Killing the iTunesHelper process worked for me.

The following worked for me with Xcode 4.1 on Lion 10.7.0:

killall iTunesHelper

The installation resumed after that. Fortunately I did not have to kill the messenger, AlertAll.

You just have to kill "alert" process, via Activity Monitor or Terminal with killall command (after quitting iTunes of course). Quide annoying bug indeed but hey - I'm not gonna reboot and reinstall all of these 4GB just because of a stupid window :)

It’s now called “AlertAll,” and killing it no longer lets the installation continue. Best just to force quit XCode’s Installer instance (right or option-click on Installer icon, choose Force Quit), and then re-begin installation, making sure iTunes is shutdown first.

I had the same issue, turns out another user was logged onto the OS with iTunes open and once I closed that instance the message went away and the installation finished.

When I killed the "AlertAll" process, the install finished, but Xcode would NOT launch. I killed the iTunes Helper process and the alert window closed and install finished correctly.

I found out that you just have to reinstall it. Just turn off your computer and turn it back on and thats it! Simple as that! ;)
