How To Set Default App For Files Mac

Learn how to make Adobe Photoshop your default image viewer and editor for popular file formats like JPEG, PNG and TIFF, as well as Photoshop's own PSD format, in Mac OS X.

Even though every copy of Photoshop, whether it's a standalone version or part of a Creative Cloud subscription, includes a free and powerful file management program called Adobe Bridge, many Mac users still prefer the Finder for locating and opening their images.

Same issue, but with some added detail: The Google Drive 'location' (within the Files App) hijacks all MS Office files. I have tried to open.xlsx,.docx, and.pptx files that I have saved in OneDrive and in DropBox, and if I try to open them from the iOS11 Files App, Google Drive hijacks them and asks if I want to Save to the Google Drive location (I don't want to do that - but the reality is. To set or change the default program that opens a file, here’s what you’ll do: Right-click by touching two fingers to your Mac’s trackpad and click or right-click your mouse on the file. Next, select “Get Info” and a long, rectangular box will appear on your Mac’s screen. Mail is likely the default email app on your Mac, but just in case you have others downloaded, you can set the default reader. Here's how: Launch Mail from your dock or the Finder. Click Mail in the menu bar at the top of the screen. Click Preferences. Click the dropdown next to Default Mail Reader. Click the app you'd like to set as the default.

While there's nothing technically wrong with that, there is one annoying problem; Mac OS X, at least by default, ignores Photoshop when we open images directly from within a Finder window. Instead, it prefers to open them in Apple's own Preview app with its basic and very limited set of image editing features. Since Photoshop is obviously our editor of choice, let's learn how to easily configure Mac OS X so that our images will automatically open for us in Photoshop every time.

  • Right-click on the file and select Other from the available options. A dialog box will appear showing.
  • Open PDF files with Preview instead of Adobe Acrobat; Open.txt files in an App other than Notepad; Open media files (MP3, MP4, AVI etc.) in VLC instead of iTunes or Quicktime; The process to switch default Apps is super-fast and easy to do, and easy to change again later any time you want.

Note that this tutorial is specifically for Mac users. For the PC version, see Make Photoshop Your Default Image Editor in Windows 10.

This is lesson 2 of 10 in Chapter 2 - Opening Images into Photoshop.

Turning On File Name Extensions

First, navigate to a folder on your Mac that contains one or more images. Here, I've opened a folder that's sitting on my Desktop. Inside the folder are four image files. Starting from the left, we have a PNG file, a JPEG file, a Photoshop PSD file, and a TIFF file. How do we know which file type we're looking at? We know because of the three letter extension at the end of each name:

A Finder window showing four image files.

If you're not seeing the extensions at the end of your file names, go up to the Finder menu in the top left of your screen and choose Preferences:

This opens the Finder Preferences dialog box. Click the Advanced tab at the top, then select Show all filename extensions by clicking inside its checkbox. Close the dialog box when you're done. You should now see the file extensions listed at the end of your file names:

Click the Advanced tab, then check 'Show all filename extensions'.

The Default Image Viewer

Let's try opening one of the images to see what happens. I'll double-click on my JPEG image ('fashion.jpg') to open it:

Opening a photo by double-clicking on its thumbnail.

Even though I have the latest version of Photoshop installed, and even though Photoshop just happens to be the world's most powerful image editor, Mac OS X completely ignores it and instead opens my photo in its own Preview app (fashion photo from Adobe Stock):

Preview has a few image editing features, but it's no Photoshop.

That's obviously not what I wanted so I'll close out of the Preview app by going up to the Preview menu at the top of the screen and choosing Quit Preview:

Making Photoshop The Default Image Viewer And Editor

So how do we tell Mac OS X to open this image in Photoshop instead of in Preview? And more importantly, how to we tell it to use Photoshop not just for this one image this one time but for every JPEG image we open in the future? It's actually very easy to do. First, Control-click on a JPEG image you want to open:

Control-clicking on the JPEG photo's thumbnail.

Then choose Get Info from the menu that appears:

A long, narrow Info dialog box will open full of details about the image. Look for the section that says Open with. You may need to click the small arrow to the left of the section's name to twirl it open. This section tells us which program Mac OS X is currently using to open JPEG files. By default, it's set to Preview:

Preview is currently our default image editor.

Click on 'Preview.app' to open a list of other apps currently installed on your system and choose Adobe Photoshop from the list. If you have more than one version of Photoshop installed, choose the most recent version. Again, at the time I'm writing this, the most recent version is CC 2015.5:

There's just one step remaining. To set Photoshop as the new default app for opening all JPEG files, not just this one, click the Change All button:

Clicking 'Change All'.

You'll be asked if you're sure you want to open all JPEG files (that is, all files with a '.jpg' extension) with Photoshop. Click Continue to confirm it:

You can close out of the Info dialog box at this point, and that's all there is to it! Photoshop is now set to open all of your JPEG files. I'll double-click once again on my JPEG image in the Finder window:

Opening the same photo again.

And sure enough, instead of opening in the Preview app as it did before, this time the photo opens for me in my latest version of Photoshop:

Photoshop is now my default image editor for JPEG files.

PNG Files

So far, so good. We've set Photoshop as the default app for opening JPEG files. But we still need to set Photoshop as the default app for opening the other file types as well, so let's run through the steps quickly. I'll return to my Finder window, then I'll Control-click on my PNG file ('butterfly.png') and choose Get Info from the menu:

Control-clicking on the PNG file and choosing 'Get Info'.

This opens the Info dialog box where we see that Preview, not Photoshop, is currently set as the default app for opening PNG files:

I'll click on 'Preview.app' and select my latest version of Photoshop from the list. Then, to set Photoshop as the default app for all PNG files, I'll click Change All:

Changing 'Open with' to Photoshop, then clicking 'Change All'.

I'll confirm that I want all PNG files to open in Photoshop by clicking Continue:

Then I'll close out of the Info dialog box. And now, when I open my PNG file from my Finder window by double-clicking on its thumbnail, the image opens in Photoshop, as will all PNG files from now on (butterfly design from Adobe Stock):

TIFF Files

Let's do the same thing for TIFF files. I'll return once again to my Finder window where I'll Control-click on my TIFF image ('portrait.tif'). Then, I'll choose Get Info from the menu:

Control-clicking on the TIFF file and choosing 'Get Info'.

In the Info dialog box, we see that just like with the JPEG and PNG files, Mac OS X is using Preview to open TIFF files. It's possible that your system may have a different app selected so don't worry if it does. All that matters is that we change it to Photoshop:

I'll once again click on 'Preview.app' and select my latest version of Photoshop from the list. Then I'll make the change apply to all TIFF files by clicking Change All:

Changing 'Open with' to Photoshop, then clicking 'Change All', this time for TIFF files.

I'll click Continue to confirm the change:

Then I'll close out of the Info dialog box. And now when I double-click on my TIFF file to open it in the Finder window, we see that it opens automatically in Photoshop (portrait photo from Adobe Stock):

PSD Files

Finally, while Mac OS X will usually set Photoshop as the default app for opening PSD files (since PSD is Photoshop’s native file format), it still never hurts to check. Plus, if you have multiple versions of Photoshop installed on your computer, it’s worth making sure that your PSD files will open in the newest version, as we're about to see.

Reset Default App

I'll return one last time to my Finder window where I'll Control-click on my PSD file ('performer.psd') and choose Get Info:

Control-clicking on the PSD file and choosing 'Get Info'.

In the Info dialog box, we see that sure enough, Mac OS X is using Photoshop to open PSD files. But, there's a problem. I still have older versions of Photoshop installed on my system, and Mac OS X has chosen one of the older versions, not the newest version. Here we see that it's set to use Photoshop CC 2014, while the newest version (at the time I'm writing this) is CC 2015.5:

Photoshop is set to open PSD files, but it's the wrong version of Photoshop.

I'll click on 'Adobe Photoshop CC 2014.app' and choose the latest version of Photoshop from the list:

Then, as I've done with the other file types, I'll make the change apply to all PSD files by clicking Change All:

Clicking 'Change All'.

I'll click Continue to confirm the change:

Then I'll close out of the Info dialog box. And now when I double-click on my PSD file in the Finder window, it opens automatically in my latest version of Photoshop (performer photo from Adobe Stock):

Whenever you double click on any file on your Mac within the Finder, the operating system will by default find the most suitable app to open it and reveal its contents. Most of the time everything will work without issues, but there are other times when your Mac will either not use the ideal app to open a file or will simply not be able to find a suitable app at all.

If you have experienced this issue before and would like to know how to solve it, read along. What causes this issue most of the time is that you might have two or more apps that support the type of file that you want to open.

For Example: Some very frequent culprits of this are archiving apps like Winrar or UnRarX, both of which support very similar file types. Another common occurrence is mix-ups between video players like VLC and Quicktime, with the latter opening files only supported by the former.

What you need to do in order to solve this issue is to change the default app for opening certain types of files, or at least choose a different app from the available ones to open a particular file. Follow these steps to learn how to do just that.

Open File with Different Program

Step 1: First, start by locating the file you want to open within the Finder.

Step 2: If you want to open the file with a different app than the one set by default only once, then all you have to do is right-click on the file, click on the Open With option and then select the app you want to use from the list of available programs.

Set Default Program for Specific File Types

Step 1: To set a different default app for all files of a certain type, you can also start by locating a file of that type first and then by right-clicking on it. This time though, locate the Get Info option and click on it.

Step 2: This will display the information panel for that particular file. On it, look for the Open with: section located almost at the bottom of the window. If it is not open, click on the small triangle until the information is displayed just like on the screenshot below.

Step 3: There, you will see a dropdown menu that will display all of the apps that support the file and are capable of opening it. Click on this menu and then select the application that you want to use to open that file type from then on.

If you don’t find the app you are looking for on the list, simply click on Other… to look for one within the Applications folder.

Step 4: Once you select the application you want, click on the Change All… button to apply the changes. Then, confirm your selection on the next window.

Once you are done, just close the information panel and you will be set to go. From now on, every time you open any file of that type, it will open in the new application you selected.
