The application Safari can't be opened -1712

Hi...

Open Activity Monitor located in /Applications/Utiliites

Select My Processes from the pop up menu on the right.

Type Safari in the search field top right corner of the window.

Now select Safari and click the red force quit button.

Try launching Safari.

i tried this with my messages app that wouldn't open. it worked. i want to thank you so much.

It worked ! . Thanks so much Carolyn !

I tried this for the Calendar applliction as I was getting the same message (can't be opened - 1712) - it worked - thank you!

Thanks Carolyn, This worked for me when my Contacts wouldn't open too. Cheers. 🙂

Thanks,

'Worked when Aperture wouldn't open.

I searched Safari and nothing came out :/

Thanks Carolyn!

Force Quitting within Activity Monitor is a quick and efficient way to handle most Applications "Not Responding" or seeming not to open with error -1712.

It can also work great for an Application that "Freezes" and is giving the spinning beach ball

Just be aware that you may lose any unsaved work by force quitting an application.

Thanks, Carolyn ... worked when the Finder app wouldn't run on my Snow Leopard system today.

Thanks, this got me out of a hole!!
