For the millions trying to use iMovie HD with Yosemite

Question

A good discussion got started in iDVD about using iMovie HD (a.k.a. iMovie 06) with Yosemite.
I am attempting to relocate some of that information into the iMovie forum.
From jboolean:
Find iMovie HD.app, control click on it and View Package Contents. Open Contents/MacOS/iMovie HD. That seems to bypass the check.
From:  hughmass:   ( says it works ! )
I can confirm that if one right clicks all the way through, and doesn't close the terminal window, iMovie HD works as usual. I put a mp4 into it, put transitions and music, and exported.   Nice discovery as there are a lot of folks who still would rather use this application from 2006. You know, so long ago.

From Old Toad:
I tried that fix and it will open but won't work further than that. That method also opens the Terminal app which lists all of the bypasses and commands  iMovie is skipping.  If you close the Terminal window iMovie closes. The project file it creates is not a package as it normally is but just a folder.   It freezes up when you try to edit an audio clip.  Then when closed it won't open the project again.
I suspect that there is some, “minor item” that is causing the iMovie HD problem with Yosemite.   Hopefully, some programming "super genius" will find a way to  lead the rest of us out of darkness.

Karsten,   One of the things I really like about you is that even when others disagree with you about “best methods” you always have sympathetic answers and great explanations.  Your technical expertise, and good humor is appreciated by me.
Quicktime will get obsolete. Now with Yosemite, the new kid in town is AVFoundation
I'm all for these improvements.  I would be delighted, ecstatic, overjoyed, to change to a new movie editor if it was half as good as iMovie HD. As you know, the new iMovie can't even set chapters!      I use chapters with Podcasts and DVDs.   I also have Final Cut Pro X.   It can set chapters but it's got way more horsepower than I need. 
When I first started using iMovie 12 years ago I never read the manual.  Didn't need to.  Starting with iMovie 08, I spent hours reading manuals and watching YouTube videos trying to figure out simple tasks.  Sometimes I think I have a mental block because I started my video editing with real film using a razor blade and tape!
Nobody forces you, to install Yosemite nor to buy a new Mac
Eventually, you are forced to upgrade.   Let me give you an example.  For a number of years I was using a very high-end analog to digital converter from Grass Valley.  This device came with a terrific piece of software that would “clean up” old footage. I could do lightning and darkening, adjust colors, and filter out “Hiss”.   Well, that software was written for the old IBM processors, the company never updated it. So I was stuck using Snow Leopard (last OS to contain Rosetta) for a long time.
As time went on, I would purchase new software that would NOT work with Snow Leopard, so I was forced to switch to Mavericks.
However, you are correct in one regard; if you have a computer that is running the software and hardware that you like and you can dedicate that computer to that one task, yes, you can continue on, more or less indefinitely until your hardware breaks.  I know people who are doing exactly that so they can keep using iMovie HD.
pretty nonsense to keep PROJECT-files
I don't keep my project files either.   I do my editing with iMovie HD, then I use iDVD to create a DVD image file (about 4 GB). That is the only item I keep.
My mind boggles at the multitude of video file formats available.  But I know this, 20 years from now I will still be able to play a DVD or at least view the DVD image file.
