FCPX version X ?

Hi There !
I have a very old project I would like to re-open, however I need version 10.0, (I believe it is 10, before the introduction of libraries)...any ideas anyone? much appreciated !

I'm presuming you don't really need to edit in the pre-10.1 version go FCP; you simply need a version that can convert the old layout into libraries. That means you mean a computer that can run version 10.2.3 or earlier. 10.2.3 is the last version that can update these events and projects. You need a computer that can run OS X 10.10 Yosemite or earlier. A newer OS won't allow you to download the old version of FCP or run it. With 10.1 - 10.2.3 you will be able to download an old version of FCP from the App Store. That can be used to update the events and projects to the library format.

Hi Tom,
Thank you so very much, I still have an old MacBook, just need to install Yosemite, and etc, etc...
Got something to do today !
Thanx again, much appreciated.
