I would like to begin coding for iPhone and iPad so I installed Mac OS X Lion on VMWare. I tried to install xcode_3.2.5_and_ios_sdk_4.2_final (3.5)GB from the Apple developer website, but I can't install it because an error message appears saying "error on installation, contact your adminstrator"

I then downloaded xcode_3.2.5_and_ios_sdk_4.2_final (4.1)GB, but when I launch it I receive an error message stating "the following disk image couldn't be opened".

I am so new to Mac OS X, what am I doing wrong?

  1. is there SDK for Lion and SDK for another version of Mac OS X?
  2. are there special configuration considerations for VMWare?
  3. how do I know which version of iOS I have?

I know this is a silly question, but I could really use the help.

There are multiple versions of Xcode for each of the Mac OS X operating systems.

Xcode 3.2.5 is for an older version of Mac OS X and will not run on Mac OS X Lion. You will need to download Xcode version 4 or later to install on Mac OS X Lion.

If you are installing the latest version of Xcode, it is now a universal binary for both Lion and Mountain Lion.

If instead you are trying to install an older version the installer will say something to the effect of "Xcode 4.x.x for Lion".

Xcode is also now available on the Mac App Store for free: click the Apple menu then click "App Store..." and then search for Xcode to install it.

  • You need to install Mac OS X system software updates. Click the Apple menu in the upper left corner of the desktop then click "Software Update..." to install the updates you need to make the installer work.

    Yes, you need to install Xcode (which includes the latest SDK) after installing the system updates to Mac OS X.

You should download it there: https://developer.apple.com/xcode/. (at least 4.3.2 for lion. latest is 4.5.1)

By the way xcode_3.2.5_and_ios_sdk_4.2_final are old version of Xcode, so it's normal you can't run it on Lion

    Yeah you can download Xcode alone, but xcode is a sdk, and ios4.2 is actually the simulator (+ documentation). We're now in iOS version 6, and Xcode 4.5.2. That's why your .dmg is obsolete. You can download Xcode, and it will automatically asking you to download latest iOS simulator + documentation.
