How do I set Preview as the PDF viewer in Safari, instead of Adobe Reader X?

I unfortunately have to use Adobe Reader X on my Mac.

In the past, I could set Preview as the default PDF viewer in Safari, but with Adobe Reader X, that option is disabled!

I already know that I can delete Adobe’s plug-in, but I’m pretty sure it will just come back the next time the damn thing auto-updates.

The “right” way is to change that setting, which (at least in previous versions) maintained the setting through updates. How do I do it?

Solution 1:

It turns out this is a known issue. Adobe has a knowledge base article that says:

Known issues

Reader's Preferences > Internet > Display PDF in Browser is always dimmed

• To disable Safari integration, delete the AdobePDFViewer.plugin from /Library/Internet Plug-ins
• To reenable Safari integration, rerun the installer over the current installation. Start the Acrobat/Reader X installer from the original media, and then follow the onscreen prompts to complete the installation.

Hopefully the plug-in doesn’t come back the next time Reader updates.
