When you download, copy, or transfer a file to your Mac, chances are the file you copy has an app associated with it. Your macOS has several apps that are set to default for common file types, be it an HTML webpage, a JPG photo file, or an MP4 video file. But some of you use third-party apps, apps like VLC music player, a photo viewer/editor, or a third-party browser like Google Chrome. In this guide, I will show you how you can set or change default apps for a file on your Mac.
Default Applications Mac
Click on Change All to make the selected app default. Similarly, you can replace defaults for other utilities on a Mac. To pick a custom email client, go to Mail Preferences, select Default Mail Reader and click on the app in the drop-down menu. Mac - Set Default Application for PDFs This document covers how to set different applications to open PDF files in macOS. By default, macOS has Preview the built in PDF reader open and render all PDFs. When you first get a Mac, you’ll find Apple has set all of the default apps for common file types: Safari for websites, Preview for pictures, etc. In most cases, these are fine, and you’ll be. Step 3: Change All Now that you’ve changed the default program for this file, the button for Change All is active. This button will set your Mac to use the selected application to open files of.
- While the likes of Mail, iTunes and Safari are set as the default applications on your Mac - meaning they launch automatically when you open an email, audio file or web link - it's easy to give.
- Back in the pre-Mac OS X and macOS days, Apple’s System 9 and earlier relied on hidden metadata to associate files with apps. File extensions, those bits of text that follow a period at the end.
While many users are good with the Safari, some of you use Chrome browser on Mac which is a third-party browser for Mac, but webpage files on the Mac are associated with default Safari app. Similarly, for music files, iTunes, and for photo files, Preview app.
These apps open the common file types by default, these are fine, and you’ll be happy enough using them. But in case you have installed another app that you think it’s better than the default apps, you can change these default apps on your Mac to something different to open the file type.
How To Set Or Change Default Apps On Mac
Before you start with the guide, you still have the option to open the file in other apps temporarily.
- Right-click on the file you want to open and select Open With where you can choose the appropriate app.
For example, a file with extension .jpg opens in the built-in photo viewer app Preview by default, but at times you want to edit that photo in some photo editing apps such as Photoshop. You don’t often do edits on Photoshop which is why you don’t need to change the default app to Photoshop, you can choose the Open With menu to open the file in other apps temporarily.
However, if you want to set or change the default apps for a particular file, here’s what you need to do.
- Right-click on a file that you want to change the app for and select Get Info.
- Click Open With if the section isn’t already expanded.
- Now click the dropdown and choose an app you want to open the file in by default.
- Click Change All & Continue when the Finder asks you if you’re sure.

The Mac default apps that come with your new Mac are great for everyday functionality. They fulfill their core purpose elegantly and simply. But when it comes to preferences to adjust and knobs to twist, Mac default apps have never been the best choice. That void is filled by third-party app makers, who include more customizable options in their own apps.
There are also apps out there that awful major upgrades from Mac default app functionality. Take Mail.app, for example: a truly broken email application that doesn’t seem to get any better. There are far better options out there on the Mac App Store, which you should definitely explore.
Once you’ve found a better default application, what do you do with the old app? It will keep popping up on contextual links and actions until you tell it to stop. Change your Mac default apps for email and everything else by following the instructions below.
Change Your Mac Default Apps: Mail
1. Open Mail.app from your Applications folder.
2. In the menu bar, choose Mail > Preferences or press Command + , as a shortcut.
3. Pick your preferred email application from the drop-down menu next to “Default email reader” at the top of the window.
If you see some non-email applications in there, just ignore them. Applications can sometimes be overly broad with their file type associates, leading to things like iTerm showing as email apps. Don’t select those: they just won’t work.
Change Your Mac Default Apps: Calendar
1. Open Calendar.app from the Applications menu.
2. In the menu bar, choose Calendar > Preferences or press Command + , as a shortcut.
3. Select your preferred calendar application from the “Default calendar app” drop-down at the top of the window.
Change Your Mac Default Apps: Web Browser
Change your Mac’s default web browser in the General pane of System Preferences.
In the General pane, click the drop-down menu next to “Default web browser” and choose your desired default browser.
Again, some non-browser applications might pop up. Make sure not to select something like Evernote.
Setting Chrome as your Default Browser
Chrome can also set itself as the default web browser from within the browser.
1. In the menu bar, click Google Chrome > Preferences.
2. Under the “Default browser” section, click “Make Default” on the right.
3. Click “Use ‘Chrome’” in the macOS dialog box to confirm.
Setting Firefox as your Default Browser
Firefox can also adjust your Mac’s default web browser from within the app.
1. Click Firefox > Preferences in the menu bar.
2. In the Startup section of the General preference tab, click the “Make Default…” button.
3. Click the “Use ‘Firefox’” button in the macOS dialog box to confirm your change.
Change Your Mac Default Apps: Image Viewer
The default image viewer on your Mac is Preview. It’s a totally acceptable application for viewing files, but it has limited editing capability. If you want to adjust your image files, you might set a photo editor as your default image viewer application instead of Preview. This is the same process for changing default apps for any other file type, as seen below.
1. Default application associations are sorted on a file extension basis. Each file extension has its own default application. Find an image file with a common image extension to change the default image viewer application for all files of that type. The most common image extensions are .jpg, .gif, and .png.
2. Right-click on the image and select “Get Info.”
3. Find the Open With section of the Get Info window, towards the middle.
4. Click the Open With drop-down menu. Select the app you want to use as your image viewer.
If you don’t see the app you want, click “Other…” at the bottom of the menu.
6. At this point, the change only applies to this individual file. To propagate the change to all images with that same extension, click the “Change All …” button below the Open With drop-down.
This change will apply to all JPG files on this Mac. Preferences for other image types, like PNG and GIF, will need to be set separately. While this might be time-consuming, it does allow a greater degree of flexibility. You might not want to open an animated GIF, for example, with the same program you use to edit photos.
Change Your Mac Default App for All Other File Types
Other files don’t always open with the application you prefer. Take HTML files, which open in your Mac’s default web browser. That’s not so useful for web developers, so you can change the default application to your preferred text editor instead.
1. Find the file you want to change and right-click it to choose the “Get Info” option.
2. Go to the Open With section in the Get Info window and choose the application you want to open this file type.
Mac Default Application Settings
3. Click “Change All …” to apply the change to all files that share that extension.
Conclusion
If you’re not seeing the apps you expect in the Open With dialog, or apps are appearing multiple times, you might need to manually edit the file type associations by customizing the macOS context menu.
Apart from the changes on the list, there’s not much you can change using the system dialogs. But there are other ways to adjust Mac default apps. Some application, like Path Finder, provide a way to suppress macOS’s built-in Finder and replace it with its own functionality. That’s a rare option, but it does exist. If you find a system replacement app, you should look for it. You might be able to wiggle around your Mac default apps for app types not listed here.
