How to disassociate a file type with an application in Mac OS

3

2

I have a Mac and I'm running Snow Leopard. I also run parallels. Now, because I opened a file with a windows application while in parallels, that file type is always associated with the windows application. So, what that means is that if I click on the file while using the Mac OS, parallels and windows gets opened up which I don't want to happen. How can I change the file type association?

Parallels and VMWare both offer settings somewhere in the program to disable that FTA linking crap. I have always recommended killing it for this reason, it is often too confusing and stupid to be useful. – peelman – 2010-11-20T16:23:07.380

@peelman, watch your blood pressure ;-) – trolle3000 – 2010-11-22T21:33:34.250

I changed jobs about a month ago, my blood pressure has been much better since then, but thanks for your concern. :) – peelman – 2010-11-24T15:09:31.740

This is what I did in Parallels Desktop 5.

  1. Open Application: Parallels Desktop
  2. Click Menu: Window/Virtual Machine List
  3. Right Click: Virtual Machine
  4. Select Pop-up Item: Configure
  5. Select Tab: Options
  6. Pick from List: Shared Applications
  7. Uncheck: Share Windows Applications with Mac OS X
  8. Optionally uncheck: Share Mac OS X applications with Windows.

I tested it with this command in Terminal:

open -a Firefox http://www.apple.com

Q: how can I allow one and only one Guest (Windows) app to be associated (FrameMaker, the main reason I have purchased Parallels), but not any others? (And still be able to use, e.g. Windows Outlook when I run into the shortcomings of host MacOS Outlook)? – Krazy Glew – 2016-10-18T22:05:13.463

This is the right answer. The other answer requires that you take that action for every file type you want to dissociate. – Nick – 2013-02-20T19:59:06.677

Right-click the file, select Get Info. In the Open with section, change the default application, and optionally click Change All. More info at this tech-recipes article.
