Is the trial available?

You can get a SetApp subscription and use OpenIn 4 as part of the SetApp subscription. SetApp offers 7 days trial. Another option is to purchase OpenIn 4 from App Store, and request a refund if you don’t like it. You can request a refund from Apple Support.


Please take a look at Example: how author of OpenIn uses the OpenIn.

I created a rule, where I configured Source App, but it does not work.

For each scheme (or file type) you create multiple Rules, and they execute in order. Order matters, please take a look at Browsers -> Rules.

Also, to troubleshoot the rules, please use the History View to see what conditions were met when link was sent to OpenIn. When you select the item from the list, you can use the toolbar to see the conditions by clicking ladybug.

In most cases, when link is sent to OpenIn it should detect source app, but sometimes applications are doing something weird for various reasons. Like DropBox instead of sending URLs, is actually sending html files.

Cannot access the OpenIn Preferences

If you have disabled showing icon in MenuBar, you don’t have an easy way to access the Preferences. Do the following, try to “open” (double-click) OpenIn in Finder a second time. OpenIn will recognize that you are opening it again, and will show the MenuBar icon for 5 seconds, so you can access the Preferences.

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 preferences, and select 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.

Can OpenIn support profiles in Browser X (Arc, …)?

Browser supporting profile is not the same, as browser allowing links to be opened in a specific profile. I am getting asked a LOT if OpenIn can support some specific browser, and a lot of them just don’t support allowing other apps to send them links to a specific profile.

Please refer to Troubleshooting Chromium Profiles to see if your browser can support opening links in a specific profile, and if it does, it is easy for me to implement that. If it does not, there is nothing OpenIn can do about it.

Note: I have contacted Arc, and confirmed with them, that they don’t support opening links in a specific profile, feel free to contact them.

Not really. We do not provide Browser extensions, and not 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.

Similarly, if you select a text in Safari you can use Services -> Open in OpenIn. Unfortunately not all browsers send URLs to services, for example, that does not work in Chrome.

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 belief 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.

Known issues

On launch OpenIn can show a tiny window with the application Icon

As of version 4.0.8 this issue has been finally fixed. Took us 8 different workarounds, tries to get it sorted.

This is an OpenIn window (not a helper). It is a bug in the in SwiftUI Lifecycle management, that I am trying to workaround. If you click on this window, it should disappear. I personally don’t see it on my laptop at all. But some users still can see it.
