Mac Error 10810
The application Finder.app can’t be opened. -10810
I ran into the unpleasant 10810 error code recently and couldn’t find any workaround without a reboot. From what I’ve gathered by searching around on the web, Error 10810 occurs when the Launch Services framework has some sort of meltdown, causing the Mac OS X Kernel to run out of available threads for anymore processes to launch. In the event that some process has got errant and is in some infinite loop of launching and hoarding threads, this will cause a rather lovely barrage of error dialog boxes (see screenshot below).
If you start getting Error 10810, you likely won’t be able to launch any other application (Finder included) and so the best thing you can do is to reboot your Mac. If you are continuously plagued by this error, then you may be using some buggy software that is launching itself into a gazillion threads causing Mac OS X to freak out.
If anyone has additional information or troubleshooting tips regarding this error, feel free to chime in.
