How to configure OpenIn as a default Browser?

Open OpenIn preferences for Browsers, if OpenIn is not configured as default browser you will see a warning, click Fix it.

OpenIn is not in the list of Default Web Browser in MacOS' Systems Preferences General, as it is not a browser. It is a tool, that can handle HTTP(s) links. And Apple requires that only browsers would be visible in there. The only way to make OpenIn as a default handler is from the OpenIn app itself.

How to configure OpenIn as a default Mail Application?

Open Mail.app preferences, and select OpenIn.app as a default Mail application. Refer to Apple Documentation. For App Store version, if you are using OpenIn Helper, you can do it from the app (SetApp version supports that out of the box).

How to configure OpenIn as a default application for a file extension?

  1. Open OpenIn preferences
  2. At the bottom of File types click on add file type… and type the file extension you want to use. Alternatively you can just drop a file with a specific extension in the list.
  3. Select applications you want to use for this file extension.
  4. Open finder and select any file with desired file extension.
  5. In Finder with the right click open Get Info dialog on the file with desired file extension.
  6. In the dialog change the application in Open With to OpenIn and click on Change All…

For App Store version, if use OpenIn Helper, you can just click on Fix It for this file extension (SetApp version supports that out of the box).

Can I configure OpenIn for Firefox profiles?

Unfortunately not at this moment. Firefox does support command line switch -P to start Firefox with a specific profile, but it does not work, if Firefox is already running.

Not really. We do not provide Browser extensions, and planning to do so. OpenIn only handles URLs opened within the macOS. Browsers don’t send links to macOS, but just open them within the Browser.

You can enable “Open in OpenIn” extension to be able to open links from one browser to another. Open System Preferences of macOS, go to Extensions, choose Share Menu and select Open in OpenIn.

In Safari you can use Share -> Open in OpenIn.

Is OpenIn available on macOS Catalina (10.15.x)?

Yes, but we don’t support development for macOS Catalina anymore. You can download free version of OpenIn 2.1.0, that only works on macOS Catalina.

Is OpenIn available for previous versions of macOS (Big Sur and Mojave)?

Yes, please refer to OpenIn 3

Not sure about OpenIn, could you recommend alternatives?

If you feel like OpenIn is not a right tool for you, please take a look on alternatives. Most of them, I believe, only support selecting browsers for URL links.

Why OpenIn cannot autodiscover Chrome profiles?

We respect other developers. In the profile directory for Chromium browsers you can find a README file with

Google Chrome settings and storage represent user-selected preferences and information 
and MUST not be extracted, overwritten or modified except through Google Chrome defined APIs.

None of these applications have their link formats documented. Unfortunately it is not as simple just to send the https link to the app to work. For example, for Zoom you need to convert https link to zoommtg (see Zoom URL Schemes), other applications expect different link formats, and usually we can find the scheme, but know nothing about what kind of parameters we need to attach.

OpenIn at this point knows only about Zoom. But even for Zoom that does not cover all cases. Our believe is to provide for you a tool, that can do anything, and it is your job to figure out how to use it. Some other application has built-in support for other applications, but we are not planning to add those.
