I am having trouble getting the Projucer to work on my Macbook Pro (OS X 10.9.5).  When I attempt to open it (after subverting the security restriction that initially would not let me open the program ...I forget the exact verbage, but it said something about not being registered with the iTunes store, or someting like that.), an ominous error is reported: "Projucer cannot be opened because of a problem. Check with the developer to make sure Projucer works with this versio of OS X. You may need to reinstall the application.  Be sure to install any updates for the aplication and OS X. This report will be sent to Apple automatically" There is a show details button, but I cannot decerne any of the info it displays when I click it. I attempted to delete the program and reinstall several times, with no success.  Has anyone had this issue?  Does anyone know what could be worng or howto go about fixing it? ---

It needs 10.10 or later, I'm afraid! ---

Please upgrade to OSX 10.11 El Capitan and install Xcode 7, then everything should work. (The minimum Projucer requirement is OS X 10.10 and Xcode 6.3.) ---

Did this change recently? Projucer 4.2.3 will not load for me on 10.10 with XCode 6.4. ![](https://us1.discourse-cdn.com/flex026/uploads/juce/original/2X/e/e0db32a2ba5ecac7734491b977ccfc9ff6186493.png) ![](https://us1.discourse-cdn.com/flex026/uploads/juce/original/2X/a/aa350968270080606d0249540f8c2af7781026cd.png)
