All my iMovie Projects have disappeared
Am using an iMac with High Sierra 10.13.4 and iMovie 10.1.8 Turned the computer on yesterday and all my iMovie Projects are gone. Have checked all the iMovie Libraries (I have 3 of them) and have been into Time Machine but there is no sign of them. Most of the projects (about 20) don't matter as I have finished with them and have separate files for them on iTunes or external hard drive but a couple I was still working on.
Bit of a mystery to me as I have been using this program for years and never had a problem like this.
Any thoughts?
