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?

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.

• Is there a way (e.g. hidden property) to "ungray" this preference setting? –  Stephan Zehrer Sep 3, 2012 at 16:32
• Just an update if anyone stumbles upon this article. I'm running Reader 11.0.07 and the plugin to delete is /Library/Internet Plug-Ins/AdobePDFViewerNPAPI.plugin –  user205336 Aug 18, 2014 at 14:38

What I did was install a later version to reset it using the following steps:

1) Remover Acrobat Reader X 2) Delete plug (AdobePDFViewer.plugin) found at /Library/Internet Plug-ins 3) Go to http://get.adobe.com/reader/ 4) Press "Choose a different version" under "Select your version of Mac OS:" 5) Select your operating system & language 6) Choose & download Reader 9.4 NOT Reader X 10.0.1 7) Install Reader 9.4 7.1) Say no to the extension for safari plug in 7.2) Say no to request to set as default 8) Reboot your system & preview should return to the default

Optional 9) I removed Reader 9.4 using the unistaller found in utilities and then removed any remaining folders left in applications (there was one labelled Adobe)

Hope this helps

• This could work but I want to stay current with the latest version. Thanks. –  Nate Mar 21, 2011 at 7:01

This question is already answered and a possible solution may be found in Adobe's knowledge base article as mentioned in @Nate's post.

However, a non-destructive method to disable Adobe Reader as PDF reader in Safari is to

• Create a new folder /Library/Internet Plug-Ins (disabled)/
• Move the file AdobePDFViewer.plugin-deactivated from /Library/Internet Plug-Ins to the newly created folder.

This way you don't have to reinstall Adobe Reader in case you change your mind later.

How to change your default PDF viewer to Adobe.

Learn how to change the way your computer opens PDF files, so you can take full advantage of editable features and more.

Stuck and wondering how to change default PDF viewer apps? Perfect for sharing, the PDF is one of the most popular file formats in use today. Most operating systems have a PDF viewer that will let you easily open these documents so you can read files, share them, or make small edits. To get the most out of your PDFs, though, you may want to switch your default viewer to the Adobe Acrobat PDF viewer , which is more feature-rich because it’s designed specifically for PDFs.

Why change your default PDF viewer to something else?

The default PDF viewer on your computer is a great option for quickly glancing at a PDF. However, while viewing a PDF you may notice changes that need to be made within it. Most default PDF viewers do not have the necessary tools to make edits or collaborate with coworkers. You may want to change your default PDF viewer to Adobe Acrobat in order to have the editing and collaboration tools you need all in one place.

How to change your default PDF viewer to Adobe PDF Viewer.

Whether you’re using Windows or macOS, your computer will automatically open any PDF with its own default app. For Windows, that’s Microsoft Edge. For macOS, it’s Preview. Here’s how to change the default PDF viewer for each of these operating systems.

Change from Microsoft Edge to the Acrobat PDF viewer:

• Right-click on the thumbnail of any PDF file.
• On the menu, click Properties.
• A new dialog box will appear. In the first subsection, the text “Opens with:” indicates which PDF viewer is set as your default. Click the Change button.
• Select Adobe Acrobat DC or Reader from the list as your default.
• Click OK to save and apply changes.

Change from Preview to the Acrobat PDF viewer:

• On the menu, click Get Info.
• Navigate to the “Open With:” section and select Adobe Acrobat DC or Reader from the dropdown list.
• Tap Change All to apply this change to all future PDF documents. Tap Continue to finish.

Now that you understand how to make Adobe your default PDF viewer, you can view, mark up text, and more with the additional capabilities unique to Acrobat. For a quick and easy way to manage PDFs — including adding comments and signatures — you can use a free online editor to help keep important documents moving.

How to change default PDF viewer on a Mac from Preview to Adobe.

Here is how to set Adobe as the default PDF viewer:

• Control-click a PDF on your computer.
• Move your cursor over Open With in the pop-up menu to see your current default viewer. In the side menu, the default viewer will be displayed at the top.
• Click Get Info.
• A new pop-up menu will open and show general information such as PDF size, creation date, when it was last modified, and more.
• Under the Open With tab you can see your default application shown in a gray box. If the tab is closed, select the small gray arrow to the right of it to expand the tab.
• Select the box with the name of your current default PDF viewer under the Open With tab.
• Click the default viewer you want to switch to.
• Once selected, the viewer will be displayed in the box. Under Use this application to open all documents like this one, choose the Change All button.
• A pop-up will appear asking you to verify that you want to switch your viewer. Click Continue to make the switch.

How to change default PDF viewer in Windows 10 from Microsoft Edge to Adobe.

You can easily change your default PDF viewer from Windows 10 to Microsoft Edge by following these instructions:

• Go to Settings.
• Select Apps.
• Choose Default apps.
• Select the Choose default app by file type option.
• Select the current default app for the PDF file format and choose the app you want to make the new default.

Why does my default PDF viewer keep switching back?

A PDF viewer switching back to a native one is a frequent issue in Windows. When a default app is changed, whether you’re using the “Default apps settings” page or choosing “Always use this app” in a file-open dialog, the association is registered as User Choice. If an app tries to register itself as the default one for a particular file type, Windows will reject its attempt to interfere with the user choice and will restore Windows as the default. For PDFs, that is Edge.

Can I change my default PDF viewer back?

You can change your default viewer back by using the steps listed for Mac and Windows users. You can always go to settings and adjust your PDF viewer to your preferred one.

Other ways to work with your PDFs.

Now you can view, mark up text, and more with all of the additional capabilities unique to the Adobe Acrobat suite of document tools.

Learning how to change your default PDF viewer is just the beginning. Here are extra resources to work with in case you’re running into other issues:

• Have secure information you need to redact? Learn how to black out text in PDFs .

9 Best Safari Extensions of 2024

Add more functionality to Safari

• Swansea University, Staffordshire University

Like Chrome , Safari isn't just a stagnant web browser, it also has additional functionality via its Safari Extension plugins which take seconds to install . A form of add-on, Safari extensions now come bundled with relevant Mac apps, as well as via the App Store. 

Whether you're looking for productivity hacks, easy ways of saving money on your shopping, or ways to make your browsing experience more pleasant, there's a Safari extension for you.

Looking for great Chrome extensions? There are plenty out there.

Grammar Checker: Grammarly

Simple and clear writing suggestions.

You need a subscription to get the most from it.

Grammarly is there for those times when you're not quite sure if your spelling or grammar is up to scratch. It highlights issues via a red line underneath a word and allows you to easily correct them, whether you happen to be typing a Facebook status or a blog post. It's a useful service that's like a little nudge in the right direction when trying to improve your writing ability. 

Cinema Style Lighting Effect: Turn Off the Lights

Neat atmospheric lighting effect.

Need to load the separate app to change settings.

One of the most effective things at the cinema is how the lights go down and you can focus solely on the cinema screen. Turn Off the Lights offers that same kind of effect on your laptop or desktop.

When on YouTube or another video based site, click the lightbulb icon on Safari, and the lights around the video playing are immediately dimmed. You can focus on the screen itself rather than everything going on around it. To get the full effect, you need to tweak some settings, but it's a neat way of adding some atmosphere when watching a video.

Price Comparer: PriceBlink

Easy to compare prices.

Only works in the U.S. and U.K.

PriceBlink keeps an eye on prices so you don't have to. Go to somewhere like Amazon or eBay, and the moment you load an item, PriceBlink pops up with its price elsewhere. You can instantly see if Amazon really is offering the best price or if there's somewhere cheaper you could switch to. If a better alternative is listed, click the site, and PriceBlink loads the alternate option in a separate tab. This simple extension could save you a lot of money over time. 

Password Management: LastPass

Extra layer of protection for passwords.

Little convoluted to setup.

Safari has built-in password management, but LastPass is much better at the job. It works across multiple devices and also gives you somewhere to store files and notes securely.

A lot of the time, you'll need to delve into the separate app to use it fully, but the Safari extension gives you the ability to generate secure passwords, quickly fill in forms, or add notes, all directly from your browser. It's a real game changer for security and privacy concerns.

Easy Coupon Codes: Honey

Easy to browse.

Most coupons are for the U.S. only.

Online, you can find thousands of coupon codes and offers, but it's likely that you forget to look them up until you've already ordered something. At the touch of a button, you can open Honey to the side of Safari, and check out the coupons available to you.

The extension offers up plenty of popular retailers such as Macy's, Bloomingdale's, eBay, and Sears. Just tap on the name of the retailer, and you can look up coupons, as well as details on how long ago they worked correctly. Honey also has a reward scheme for extra bonuses. 

Link Saving: Pocket

Great for storing links for later reference.

You need to sign up first.

How often do you find yourself looking at a great long-form article and realizing you don't have the time to read it right now? With Pocket, you just need to click the "Save to Pocket" button, and the link saves to your account so you can easily consult it later on. It works across multiple devices and you can tag and label articles so that everything is neatly organized. 

Ad blocker: Adblock Plus

Easy to set up.

Settings can be a little tricky.

No one likes obtrusive ads when trying to read an interesting article online. Adblock Plus makes it simple to block ads and tracking ads that bug you, while "safelisting" websites that you want to see all the ads for. Adblock Plus takes a responsible approach to ads with an option allowing for "acceptable ads," appreciating that website owners still need to generate revenue, while saving you the hassle of the worst kind of adverts.

Picture in Picture: PiPer

Supports many different video sites.

Liable to dent your productivity.

Being able to multitask is always a valuable skill. While you can switch between windows and tabs, it hasn't been possible to have YouTube or Netflix running alongside what you're working on in Safari.

PiPer changes all that. Via its extension, you can easily place a video in the corner of your screen, allowing you to continue working while the video plays to the side. It's a great tool for juggling multiple things together.

Translation: Translate

Translates from dozens of languages.

You need to poke around in settings to gain full benefits.

One of the best things about Chrome is its ability to translate websites for you. Translate brings that functionality to Safari. Simply go to a website, tap the translate button, and Translate converts everything to English via Google Translate or Bing Translate. It takes a moment or two but you can see it being converted before your eyes which is neat. Translations are reasonably accurate too.
