Most files on a Mac open with a simple double-click, but not every file behaves the same way. When you double-click a file, macOS automatically chooses the right app for that file type. For instance, a PDF will typically open in Preview, while a Word document opens in Microsoft Word, or in Pages if you don’t have Word installed.<\/p>\n

Sometimes, though, things don’t go quite as smoothly. Your Mac might not recognize the file type, you may not have the app that opens it, or the file itself is damaged.<\/p>\n

In this guide, we\u2019ll look at the different ways you can open your files, how to use a different app when you need to, and what to do if a file refuses to open.<\/p>\n

The quickest way to open files on a Mac<\/h2>\n
\n

You can open most files on your Mac by double-clicking them. Your Mac recognizes most common file types and opens them in the app it normally uses for that format.<\/p>\n

When you download something from the web, it usually goes straight into your Downloads folder<\/a>, which you can find in Finder\u2019s sidebar. From that folder, you can double-click the file to open it.<\/p>\n<\/div>\n

Many web browsers also let you open recently downloaded files directly from their downloads menu by clicking them.<\/p>\n

Email attachments work much the same way. Some email apps let you click and preview the file inside the message, while others require you to download it before you can open it.<\/p>\n

If a file refuses to open when you click it, the solution is simple \u2014 your Mac might need a different app to open it, or it might be a file type macOS doesn’t support. If that happens, you can pick a different app yourself.<\/p>\n

Common ways to open files on a Mac<\/h2>\n

Other methods come in handy if a file won’t open with a double-click or if you want to use a different app for the job.<\/p>\n

Right-click and select Open<\/h3>\n

Right-clicking (or holding Control while you click) and choosing Open does the same thing as a double-click. It’s another way to get there if you prefer the menu.<\/p>\n

Use Open With<\/h3>\n

If you want to use a different app than usual, right-click the file and hover over Open With<\/strong>. A side menu will appear showing the other applications on your Mac that can read that specific file. This is the go-to when your usual app won’t open a file. You can also set an app as the default for that file type from the same menu.<\/p>\n

\"A<\/p>\n

Drag the file onto an app<\/h3>\n

You can also drag a file directly onto an application’s icon, either in your Dock or inside your Applications folder. If the app supports that file type, the icon will light up, and letting go of the file will open it inside that app.<\/p>\n

Open the file from within the app<\/h3>\n

Some apps let you open files from within the app. With the application open, click File<\/strong> in the menu bar at the top of your screen, choose Open<\/strong> or Open File<\/strong> (depending on the app), and find the file you need from the window that pops up.<\/p>\n

\"A<\/p>\n

Use a keyboard shortcut<\/h3>\n

If you prefer using your keyboard, highlight a file on your Desktop or in Finder and press Command<\/strong> + O<\/strong> (or Command<\/strong> + Down Arrow<\/strong>) to open it. If you\u2019re already working inside an application, pressing Command<\/strong> + O<\/strong> will also open that app’s Open window so you can choose a file.<\/p>\n

Open a recent file<\/h3>\n

Some apps let you jump back into a project you recently closed. Select File<\/strong> in the top menu bar and click Open Recent<\/strong>. It shows a short history of your latest documents.<\/p>\n

If you find you need a longer history, you can increase this limit in System Settings<\/strong> > Menu Bar<\/strong> > Recent documents, applications, and servers<\/strong>.<\/p>\n

\"A<\/p>\n

Find and open files with Spotlight<\/h3>\n

If you know a file\u2019s name but can\u2019t remember where you saved it, press Command<\/strong> + Space<\/strong> to bring up Spotlight search<\/a>. Type in the name, and once the file shows up in the list, you can press Return<\/strong> or double-click to open it.<\/p>\n

Preview files with Quick Look<\/h3>\n

If you only need a quick glance at a document or image without waiting for an app to load, select the file and press the Space bar<\/strong>. This opens a fast preview that you can dismiss by pressing the Space bar<\/strong> again.<\/p>\n

\"A<\/p>\n

Open files from the Dock<\/h3>\n

You can also check your Dock for quick access. Right-clicking an app icon will often bring up a small list of your most recently opened items, letting you jump straight back into your work without opening a Finder window.<\/p>\n

Open files from Terminal<\/h3>\n

If you use the Terminal, you can open files directly from the command line. Type “open” followed by a space, then drag your file right into the Terminal window to paste its path, and press return<\/strong>. Most Mac users won\u2019t need to use Terminal for this, but it\u2019s helpful if you already spend time working in that environment.<\/p>\n

How to choose which app opens a file on Mac<\/h2>\n

Sometimes the problem isn’t the file itself. It’s the app macOS is trying to use to open it. If a file won’t open or opens in the wrong application, you can choose a different app instead.<\/p>\n

If you only need to do this as a one-off, right-click (or Control-click) the file and move your cursor to Open With<\/strong>. Choosing an app from this list opens the file just this once, leaving your usual settings exactly as they were.<\/p>\n

For files you work with all the time, you can set a permanent preference so they always open where you want them to. Right-click the file and choose Get Info<\/strong>. In the window that appears, look for the Open with<\/strong> section, select your app from the list, click Change All<\/strong>, and choose Continue<\/strong>. This ensures every similar file opens the same way from now on.<\/p>\n

\"A<\/p>\n

If your Mac tells you there is no application available to open a file, it means the computer doesn’t have the right tool for that specific format yet. You’ll need to see what kind of file it is and find an app that recognizes it.<\/p>\n

When you need to download a new app<\/a> for an unfamiliar file, stick to the Mac App Store or the developer\u2019s official website. This lowers the risk of downloading unsafe or unreliable software.<\/p>\n

How to open different file types on a Mac<\/h2>\n

Most of the files you come across every day will open when you double-click them because your Mac already knows how to handle standard documents, photos, and videos. When a file doesn’t open right away, it’s usually because it was made for Windows or requires a specific app you don’t have.<\/p>\n

If you come across a file you don’t recognize, take a look at its extension (the letters after the final period in the filename). Those letters tell you what kind of file it is, and how to open it safely.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

How to open RAR files on a Mac<\/h3>\n

RAR files are compressed packages similar to ZIP files, but macOS doesn’t include built-in tools for opening them. To open one, you need to download a separate application like The Unarchiver (free, on the Mac App Store) or Keka. Once installed, either app can extract the files for you.<\/p>\n

How to open EXE files on a Mac<\/h3>\n

EXE files are Windows programs, which means they aren’t built to work on a Mac. If someone sent you one, it was likely meant for a Windows PC.<\/p>\n

You can check the creator’s website to see if they make a specific version for Mac. If they don’t, opening that file would require setting up Windows on your Mac<\/a>.<\/p>\n

How to open ZIP files on a Mac<\/h3>\n

ZIP files are one of the easiest file types to open on a Mac. Simply double-click the file, and your Mac will automatically extract everything into the same folder.<\/p>\n

How to open DMG files on a Mac<\/h3>\n

A DMG file is essentially a digital package used to deliver software to your Mac when you download an app directly from a website instead of the App Store.<\/p>\n

When you double-click the file, a window will usually appear with instructions for installing the app. In many cases, you’ll drag the app into your Applications folder, though some installers may ask you to double-click an installation package and follow a few on-screen steps.<\/p>\n

How to open video files on a Mac<\/h3>\n

While most videos play right away using the built-in QuickTime Player app, certain formats like MKV or AVI won’t open on their own. For those, you\u2019ll want to use a trusted third-party media player.<\/p>\n

What to do if a file won’t open on your Mac<\/h2>\n

If a file won’t open, the problem is usually related to the app, the file itself, or your Mac\u2019s built-in security. Before assuming the file is broken, there are a few straightforward things you can check.<\/p>\n
