Xcode 4.0.1 in App Store; how do I update from Xcode 4.0?

Thanks for the procedure.

A couple of notes for anyone else looking here:

Point #2: ("As root, again use pkgtool ...") Not sure why you use the word "again." What and where is pkgtool? I can't find it. I skipped this step.

Point #3: ("Weed out any remnants of Xcode from ~/Library") There's a lot of stuff in ~/Library, assuming you mean ~/Library and its subdirectories. Can you narrow it down any? I ended up not deleting anything.

The installation did proceed to work, as far as I can tell.

I had the similar problem as sspg and followed his procedure with success.

In regards to your Point #2: I believe sspg meant pkgutil instead of pkgtool;

Point #3: I believe one weeds out Xcode remnants from ~/Library/Developer.

Yea downloading 4GB can be a pain, I recommed using a torrent for this. Not sure if it's legal, but maybe apple should offer an official torrent or download manager for this.

Your method looks useful, thanks. But I couldn't do step 2 as I couldn't find something like pkgtool. I did have pig-configuration which seemed to think there were no XCode packages around. But now Xcode is fully erased but still the App Store thinks it is still installed. Stuck. Any more help would be appreciated ...

Try pkgutil instead of pkgtool.

Also, try navigating to the Purchased tab in the App Store after using sspg's procedure; I did that and was able to re-install Xcode; when I navigated directly to the app, the App Store also told me it was already installed.

So the steps are:

1. sudo /Developer/Library/uninstall-devtools -mode=all (so that you get rid of everything)

2. restart

3. delete or compress the "Install Xcode.app" (so that AppStore will let you install Xcode - otherwise it will say that it's already installed)

4. install it again from AppStore.

I had the same problem. I had xcode 4.0.1 and I can't update it to 4.2.1 from app store. The button show Installed app. I have delete the Applications/Install xcode.app and now I can download again ! the new xcode.

I think I found the solution and it's much simpler. When you open up the App Store page to upgrade from 4.2 to 4.2.1 and the button says "Installed", and clicking on it has no effect you're doing the wrong thing. You need to instead click on the "Updates" button on the app store toolbar at the top of the window.

Voila - xCode 4.2 is upgraded to xCode 4.2.1.

Not the most seamless user experience Apple...

Please let me know if this helps you...

(I'm kind of surprised people are being told to completely uninstall xCode - this looks like a case of simple bad usability).

I've been following this thread but I havent been able to find a solution to my problem-

I had xcode 3, then upgraded my mac to snow leopard- i have 10.6.8 now. I cannot, however, download xcode 4.0 - apple says that i need to upgrade to Lion (10.7)??

That's another $30 i need to shell out in order to get xcode 4?

I noticed that xcode 4 was originally available for 10.6, but now i only find links for xcode 4.2

Can someone help me download xcode 4 for 10.6.8?

Thanks.

got same for 4.4.1

cant update 4.4.1

deleting from Applications didnt works!
