Workaround to the „The application Finder can’t be opened (-10810)“ error in Mac OS X

Apple implemented a cool new feature in Snow Leopard: from time to time (I encountered this problem about 5 or 6 times sind 10.6 was initially released) Finder.app will quit and if you try to restart it, OS X will present you with a nifty little error message, namely: „The application Finder can’t be opened (-10810)“.

And, true, once you’re at this stage, Finder can’t be opened again unless you reboot the whole machine. Except if you know you’re way around the Terminal.

Fire up Terminal and enter this command (without the quotation marks) „/System/Library/CoreServices/Finder.app/Contents/MacOS/Finder &“ This will give you a new Finder window and Finder will work without any problems. However, Finder will quit as soon as you close the terminal and you’ll be running into that mystical „-10810“ error again.

To prevent this, add a „disown“ to the command above: „System/Library/CoreServices/Finder.app/Contents/MacOS/Finder & disown“.

However, I recommend rebooting you’re machine as soon as you have a few minutes to spare. I took a look at the Apple forums and it still seems unclear what the underlying problem for this is.

    This is not a fix but a workaround.

    Links to the Apple Forum would be appreciated.

    • Thanks. The fix/workaround mix-up was my fault, the missing link the fault of my blogging client. Both is now corrected.

    great solution – thanks so much – it works – however – it definitely seems to be happening when i plug in external usb or hard drives – possibly time machine? – any resolutions, which are permanent or do we have to wait for Apple to sort it? – perhaps a software update? all seems to be done? – or do we all jump onto Lion OS? –

  6. You can both save your drive and save your data
    as well. With a total media capacity of 250 sheets, it will
    print the standard media sizes of folio, legal and letter.
    Even if you are unable to resolve the issue then you need to reinstall fresh operating system.
