Lion 10.7.3: Apple is not currently accepting applications built with this version of the OS

Okay, I got it working in a way that's completely unsafe...so I can't really say that this is a great way of fixing this problem.

Anyways:

I took a look at the SystemVersion.plist, and it turns out our build for 10.7.3 is 11D50b (b being beta of course). Of course, 10.7.3 wasn't advertised as a beta...if it was I wouldn't have upgraded.

Basically I changed the SystemVersion.plist in /System/Library/CoreServices to:

Build Number: 11C74ProductUserVisibleVersion: 10.7.2ProductVersion: 10.7.2

You can do this with TextEdit after changing permissions, or if you're familiar with nano, simply:

sudo nano /System/Library/CoreServices/SystemVersion.plist

As always, be extra careful when doing anything with sudo.

From there, I restarted Xcode (make sure you do this, I tried without restarting Xcode and it wouldn't work), cleaned, archived and was then able to submit successfully.

Immediately after this, I shut down Xcode and made sure to change everything back to how it was before:

Build Number: 11D50bProductUserVisibleVersion: 10.7.3ProductVersion: 10.7.3

I would absolutely not try restarting or anything funny like that, dunno what might happen. But this worked for me.

Edit 12 March 2012:I contacted Apple directly using a paid support ticket. It turns out that this was a bug within the Mac App Store. Their team has fixed the problem. Submitting With 11D50b should now work.

Solution to the problem on OS X 10.7.3 with Xcode 4.3

You will need to change the SystemVersion file, this can be done with the commandsudo nano /System/Library/CoreServices/SystemVersion.plist (ctrl o, to save)

My current file looks like this:

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs$<plist version="1.0"><dict>    <key>ProductBuildVersion</key>    <string>11D50b</string>    <key>ProductCopyright</key>    <string>1983-2012 Apple Inc.</string>    <key>ProductName</key>    <string>Mac OS X</string>    <key>ProductUserVisibleVersion</key>    <string>10.7.3</string>    <key>ProductVersion</key>    <string>10.7.3</string></dict></plist>

Change 11D50b to 11D50, restart xcode and clean your code. Then submit again.After submitting, remember to change the file back to the original.

Ok i had the same problem and i also had installed Xcode 4.3 already, because i expected that will solve that issue. Xcode 4.3 requires 10.7.3 so it is not possible to change the SystemVersion.plist to 10.7.2 but just removing the b in end of 11D50b and restarting Xcode let me submit my App.
