Why won't preview open pdf files anymore?

Here's the first beta of "Preview Reset", which should help track down any other applications on your machine that are messing with Apple's Preview. When the reset button is clicked, it moves them to the trash, resets Apple's Preview and then rebuilds the Launch Services database.

In our tests, once the apps have been moved to the trash, there isn't even the need to restart the machine.

I have never installed Shine, or any software from Ohanaware, and have had this issue.

The only system activity that seems related is I changed the default program to open PDFs from preview to Adobe Acrobat, but that could be entirely coincidental.

The message said everything was fine, but the problem still persisted until I chose the reset option. Once completed, I can open PDFs again. Thanks!

I did not install any software by Shine either, but running your app and clicking reset fixed Preview for me. Thanks? 🙂

I also didn't install any Shine software, but running your app and clicking reset fixed the problem. Thanks!!

Thank you...this worked so well for me 🙂🙂

You're a genius. Thanks.

I've been fighting with this for a month, and this command fixed it. I did not even close all the apps, I just ran it, and then I could edit and annotate PDFs again. for me preview was listed as an option for PDF files, but it would crash on open every time.

This has worked for me so far.

Very grateful for your work on this!

Tried some other methods for fixing Preview and this is the only one that worked. Fixed it in a minute. Thank you!

solved, thank you very much for the link 🙂!

I googled this http://www.macupdate.com/app/mac/55459/preview-reset/download link, since the one above seems to be broken. Sorry, tried again, and it works now 😉

This was extremely easy and extremely helpful. Just hit the reset button and everything worked itself out. Thank you!

Thank you so much!!! This link checks out and fixed my problem. Even if it says your preview is fine, hit the reset button. Then everything is fixed!

Worked like magic! For me 'Notability' was causing the problem. This fixed the problem in seconds. Many thanks

Thanks for your post Simon. Notability was also the problem for me. Had been going on for weeks and no solution worked. Once I i trashed notability, boom, preview back.
