Prevent MP4 from opening in VM

[JamieS73]

My default app setting in macOS for MP4 files is QuickTime, yet when I double-click an MP4 file, Photos in Win10 opens. How do I prevent Photos from hijacking the default setting even when QuickTime is set as default?

Hi @JamieS73 , please re check the default program on your mac and check if it is set to Quicktime (mac) , if the issue still persists, please try to uninstall and reinstall Parallels Desktop for mac.

I checked the default setting in the right-click menu, and it was still set to use Quicktime. The file still opened in the VM. I reinstalled Parallels, no change. I checked the "Open with:" field in Get Info which also was set to Quicktime. I clicked "Change All..." and apparently settings were updated because now it works correctly.

Nice to know that it works as expected now. Please post again for additional queries.

Hi,
I'm having this same issue. Everything was fine until i opened some files off a microsd card in windows while I was in bootcamp. When I came back to my mac side I tried opening up some other videos and now every time I try to open a video file it launches parallels and opens in the windows photos app. Also all of my video files have the parallels icon next to their name. I have tried setting my default to preview but it does not work. What can I do to fix this? Thank you

Hello, did you try the solution provided by @JamieS73 above?

This worked: I checked the "Open with:" field in Get Info which also was set to Quicktime. I clicked "Change All..."
However, I have been plagued and ANNOYED by this behavior by Parallels - to take over my file opening preferences without my permission. I've NEVER told Parallels to wake up, start Windows, and use the awful Windows Media Player when I click on an MP4 file on my Mac. Wasted SOOOO much time waiting for Windows to boot each time I forgot about this bad (and unwanted) file association that I didn't ask for.
Parallels, dev team, you might look to this. "Default behavior" can be a terrible tyranny.

I was also annoyed by this, what did the trick for me was disabling "Share Windows applications with Mac"

Where did you find this option in the preferences?

 

[EwaldV1]

Yeah in the Control Center, click the gear icon, then the "Options" tabs, and click "Applications"
