At one time there was some thought of releasing a mac version of premiere elements. Is this idea completely gone? If so, that's too bad. Imovie is too basic and Premiere too complex. Final Cut express just is about three years behind the times. Premiere Elements for Mac would fill a great niche.
Welcome to the forum.
Through PrE 7, it was PC-only. I do not know about PrE 8, which was just released. Maybe the Adobe site can answer your question.
Steve G., or ATR might be able to let you know. I have heard nothing about PrE 8 being ported for the Mac, but since PrPro has been, since CS3, maybe? I just do not know.
You can view thw System requirements for PE8 at this link:
There is no mention of any Mac Operating Systems, only Windows based Systems are supported at this time...
I can tell you absolutely that no version of Premiere Elements will work on the Mac operating system.
