Booted Parallels 9 this AM. (It had been running just fine until then, managing several Windows 7 and XP VMs, on my OS X 10.8.4 MacBook.) Was notified that an update was available. Approved the download and the installation and now... nothing. Or rather, the "Parallels Desktop" round rectangle startup window with the spinning whirly. And only that. I let that run for 4 hours, hoping that something more would happen. Then force quit. Relaunching Parallels 9 now results in the same thing: no virtual machines are listed, I never make it past the first stages of loading the app, and I have no access to my virtual machines. Has anyone else had this trouble? There are a bunch of prl_client_app errors in Console, of this sort -- 9/14/13 1:45:40.561 PM prl_client_app: objc: Class WebCoreMovieObserver is implemented in both /System/Library/Frameworks/WebKit.framework/Versions/A/Frameworks/WebCore.framework/Versions/A/WebCore and /Applications/Parallels Desktop.app/Contents/Frameworks/QtWebKitPrl.framework/Versions/4/QtWebKitPrl. One of the two will be used. Which one is undefined. -- but I cant' tell if they matter at all. I very much need access to those virtual machines for a project. After the Access debacle, I'm ready to give up on Parallels.
