How can I reinstall iMovie onto my iMac
Hi, my children had a play with iMovie, and now there sounds option has gone from the left panel. How can I reinstall to start this over, as I'm not sure what else is missing etc. I have tried going to Mac App Support, but if I try and install it again, it just opens up iMovie in the state it is now. I don't have an install disc either. Wondering if I can completely delete it off my hard drive, and then be able to reinstall it from Mac App Support? Would that work?
Many thanks in advance!
