Monterey 12.3 Broke The Mini-DV Connection

I am having this import problem as well with iMovie. Stopped importing from my Sony GV-D200 and Canon VIXIA-HV30, to my Mac M1 Mini with OS12.3.1. I have tried all solutions from this thread except going back to Big Sur. I did install from the App Store iMovie update 10.3.2 today, and that had no effect. When I check "About This Mac" - "System Report" - "Hardware" -"Firewire", I see my device listed, but again iMovie does not for importation. This is definitely an OS 12.3.1 issue.

This is definitely a problem with the 12.3/12.3.1 updates and needs to be reported in Apple Feedback Feedback - macOS - Apple (As far as I know Apple don’t monitor these Community discussions - probably the noise to signal ratio is too poor.)

I came across the video linked by sdschramm before I got to this forum which clearly demonstrates where the issue lies: https://youtu.be/vfwfZgGI3JY?t=1

Hopefully the predictions about an early fix are true.

It is working with 12.4

The fix is to update to Monterey 12.4.

Just updated to 12.5 and MacBook Air can see my Panasonic mini dv recorder, thanks for the info!

I have the exact same problem as mentioned above. I have reported the bug to Apple so I hope they can fix it in the next update to Monterey. My temporary work around was to borrow my sister's older firewire iMac with an older version of iMovie. Everything worked fine with that setup, of course.

I hope a fix comes soon.

Same happened to me,

Having MAC Studio running MACOS 12.3.1, connected Thunderbolt 3 to Thunderbolt 2 and Thunderbolt 2 to Firewire 800, at last with a Firewire 800 to DV cable, not detecting my camera, I was thinking if my cable were bad.

Then after reading this thread, connect the same cables and camera to my macbook pro 14 base model with MACOS 12.1, it work perfectly fine.

This is a bug Apple need to address for sure.

I reported this bug here and encourage others to do likewise:

Feedback - macOS - Apple

As this is obviously a bug in Monterey 12.3 update suggest everyone affected with problem message Product Feedback-Apple.

Any version prior to 12.3.1 will work, the problem is within the DV import module that is common to iMovie and FCP, the issue will be fixed in the next Monterey update

@Geoff: macOS 12.3 and 12.3.1 have the issue. Only 12.2.1 and older will work.

Try updating to Monterey 12.5 in addition to a redownload of iMovie (previously mentioned).

Actually, you can update to Monterey 12.5 now, latest version.

Yes this is definitely an issue with the macOS 12.3 update. This video has a lot troubleshooting showing the problem only happens once updating to that version: https://youtu.be/vfwfZgGI3JY?t=1

You might try posting your issue in the Mac OS System Software forum.
