iPhoto won't open 9.4.2 and OSX 10.7.5

Question

I&#x27;m not sure about when this happened, but I can no longer open iPhoto.  It goes to an error log that says "iPhoto Unexpectedly Quit".Incidently, my Displays, Clock and Icon in the tool bar no longer show up either.I&#x27;ve tried reinstalling the 10.7.5 update, reinstalling iPhoto, Command+Option at startup of iPhoto, repairing permissions (always shows fixed permissions, never got it to come back clean), repair disk to no avail.Here is the first 30 or so lines from the log.Anyone have any ideas?  This is on a Mac Pro 2.66GHz.Thanks,MikeProcess:         iPhoto [376]Path:            /Applications/iPhoto.app/Contents/MacOS/iPhotoIdentifier:      com.apple.iPhotoVersion:         9.4.2 (9.4.2)Build Info:      iPhotoProject-710042000000000~1Code Type:       X86 (Native)Parent Process:  launchd [179]Date/Time:       2012-11-03 22:01:30.397 -0700OS Version:      Mac OS X 10.7.5 (11G63b)Report Version:  9Interval Since Last Report:          724 secCrashes Since Last Report:           5Per-App Crashes Since Last Report:   5Anonymous UUID:                      FD9BE12C-3C87-4CD9-A230-B4E275A601C6Crashed Thread:  0  Dispatch queue: com.apple.main-threadException Type:  EXC_BAD_INSTRUCTION (SIGILL)Exception Codes: 0x0000000000000001, 0x0000000000000000Application Specific Information:dyld: launch, running initializers/usr/lib/libSystem.B.dylibxpchelper reply message validation: sandbox creation failed: 516The file “com.apple.iPhoto.plist” couldn’t be saved in the folder “Preferences” because a file with the same name already exists.Application Specific Signatures:sandbox creation failed: 516Thread 0 Crashed:: Dispatch queue: com.apple.main-thread0   libxpc.dylib                            0x9493e54e runtime_init + 20141   libdispatch.dylib                       0x91e8ec27 dispatch_once_f + 502   libxpc.dylib                            0x9493ed92 _xpc_runtime_set_domain + 3503   libxpc.dylib                            0x9493b9af _libxpc_initializer + 5784   libSystem.B.dylib                       0x92bf47a7 libSystem_initializer + 1995   dyld                                    0x8fec0203 ImageLoaderMachO::doModInitFunctions(ImageLoader::LinkContext const&amp;) + 2516   dyld                                    0x8febfd68 ImageLoaderMachO::doInitialization(ImageLoader::LinkContext const&amp;) + 647   dyld                                    0x8febd2c8 ImageLoader::recursiveInitialization(ImageLoader::LinkContext const&amp;, unsigned int, ImageLoader::InitializerTimingList&amp;) + 2568   dyld                                    0x8febd25e ImageLoader::recursiveInitialization(ImageLoader::LinkContext const&amp;, unsigned int, ImageLoader::InitializerTimingList&amp;) + 1509   dyld                                    0x8febd25e ImageLoader::recursiveInitialization(ImageLoader::LinkContext const&amp;, unsigned int, ImageLoader::InitializerTimingList&amp;) + 15010  dyld                                    0x8febe268 ImageLoader::runInitializers(ImageLoader::LinkContext const&amp;, ImageLoader::InitializerTimingList&amp;) + 6211  dyld                                    0x8feb2694 dyld::initializeMainExecutable() + 21412  dyld                                    0x8feb6f99 dyld::_main(macho_header const*, unsigned long, int, char const**, char const**, char const**) + 223813  dyld                                    0x8feb02ef dyldbootstrap::start(macho_header const*, int, char const**, long, macho_header const*) + 63714  dyld                                    0x8feb0063 _dyld_start + 51Thread 0 crashed with X86 Thread State (32-bit):  eax: 0x000000cc  ebx: 0x7b647e90  ecx: 0xc00ac14c  edx: 0x00000000  edi: 0xc00ac080  esi: 0xac513410  ebp: 0xc00ad0b8  esp: 0xc00ab7c0   ss: 0x0000001f  efl: 0x00010286  eip: 0x9493e54e   cs: 0x00000017   ds: 0x0000001f   es: 0x0000001f   fs: 0x00000000   gs: 0x00000037  cr2: 0x7b651000Logical CPU: 3

Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (On 10.7: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)(Remember you&#x27;ll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you&#x27;ve moved your library you&#x27;ll need to point iPhoto at it again.)What&#x27;s the plist file?For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you&#x27;ve changed any of these things you&#x27;ll need to reset them. If you haven&#x27;t, then no bother. Trashing the plist file is Mac troubleshooting 101.

I&#x27;ve got the same issue reporting "sandbox creation failed: 516" and killing these files didn&#x27;t solve my issue. @mmills, were you able to resolve your issue?

I know this is an extremely old post, but I googled this problem and it was the first hit. So, for anyone who stumbles upon this I was able to open iPhoto by holding down Shift + Alt and clicking once on the app in the dock. Not sure if this will help anyone else, but hopefully it does!
