Hi, My first post so thanks in advance I recently bought a refurbished eMac which had Leopard 10.5.5 installed but no developer software and no discs. Because my Internet connection seems to consist of two tin cans connected by a bit of string I asked a friend of mine to head over to the Apple site and get me a copy of Xcode - I gave him a link for it but I can't tell which version I have. The DMG file I got back opened properly and inside it were these three files: dotmacsdk_2.0.dmg.part gcc42preview1.dmg.part xcode_3.0.dmg.part Only the first one will mount and when I do that I get the software licence screen. When I click 'ok' it waits for a couple of seconds then I get this message: Unable to attach "dotmacsdk_2.0.dmg.part". (codec overrun) Before I try and diagnose this error I want to check with the knowledgeable folk here whether these files look right - the file sizes (respectively) are 5.6MB 50.2MB 1.16GB but I would have expected at least one of them to have a .dmg extension. Could anyone offer any advise please? Thanks!
