As with all operating systems, OS X comes with a bunch of standard apps that are used to launch common file formats, such as Pages for text documents, Preview for PDF documents, and QuickTime for videos.
But maybe you don’t want to use those apps. If that’s the case, the good news is that changing the default launch application for a particular file type is very easy.
Let’s say we want to open text documents using LibreOffice instead of the default Pages app (learn why LibreOffice is so great). Assuming LibreOffice is already installed, here’s all you have to do:
- Right-click any text document and select Get Info.
- Or select the text document and use Cmd + I.
- Scroll down to the “Open With” section.
- Select a different app, in this case LibreOffice.
- Click Change All to make all text documents choose to open using LibreOffice. If you don’t click it, only this particular text document will launch using LibreOffice.
That’s all! Now you can double-click the text document and it won’t open with Pages anymore. You can do the same thing with ANY files and set them to launch using ANY app on your system. It’s great for keeping your system organized and sane.
