I just got my Mac upgraded to 10.7.2, just to be able to install Xcode 4.3.3.
However, when I try to install Xcode 4.3.3, it says that it requires a minimum of OSX 10.7.3.
Then using the "Software Upgrade" tool it detects successfully for me that a combined upgrade to 10.7.4 is available. As I select Install Item, the download starts however, it fails after complete download (taking two hours) saying something like "the update cannot be saved".
I have done this twice already, and followed it up until 5 minutes were left. I have also checked that there is enough space (60 GB) available on my hard disk, while the update requires around 1.5 GB.
The question is what is causing the problem mentioned in bold above.
