I have a MacBook Pro with 16GB of RAM that can't be expanded. I tried to publish my first slide show as HD/4K, high quality, and 60 fps, but was unable to due to the fact my computer ran out of memory at about the 3% complete point. I tried again with low quality and 50 fps, but had the same problem at about the 9% complete. Next I tried AVI format and although it published and plays fine on my computer, none of my TV's are compatible with the AVI format. Any suggestions? I would be happy with publishing an MOV or MP4 file, that is not necessarily HD or 4K, but don't see how to do this. Is another option to split up my slide show, publish several smaller slide shows (less memory intensive) and then combine them into a single larger slideshow? Thank you, Mike
