Hi guys! I am pretty much a noob so I don't understand why i suddenly can't open my finder. I have a Macbook Pro and I am not really sure what version of SNow Leopard I was running when I updated my software as I wasn't really able to monitor the updates. All I did was to simply hit the 'Software Update' under the apple icon on the upper left side of the screen and then I stepped out. When I came back and my computer was rebooted I noticed that some programs on my dock such as itunes has changed icon, so I guess itunes was updated. Problem is, all programs that has changed icon, hence, was probably updated would not launch. And some sections in the System Preferences such as Desktop & Screensaver also wouldnt launch. Some programs, such as firefox, would open but for a few minutes but would eventually crash. And yeah, I keep on getting the "Finder can't be opened 10810" and "Finder quit unexpectedly". I would take a screenshot of those but my desktop also does not contain anything. I tried typing /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder & but I get this result: Library not loaded: /System/Library/PrivateFrameworks/DataDetectorsCore.framework/Versions/A/DataDetectorsCore Referenced from: /System/Library/Frameworks/Quartz.framework/Versions/A/Frameworks/PDFKit.framework/Versions/A/PDFKit Reason: no suitable image found. Did find: /System/Library/PrivateFrameworks/DataDetectorsCore.framework/Versions/A/DataDetectorsCore: open() failed with errno=-22 I also tried using the disk utility but I get the message "Disk Utility can't be opened because of a problem: Check with the developer to make sure Disk Utility works with this version of Mac OS X" As much as possible I would not like to reformat because of the programs already installed on my Mac and my bootcamp. Any help would be appreciated.
