Well, pre-building the 1:1 previews didn't help. Either did any of the other items I tried. If the problem is that there is no Macbook Pro you can buy that can handle Lightroom with the Z7 files, then I guess I'll need to switch to another editing software, as I already invested in a top of the line laptop, and am not going to switch to a windows machine. I would respectfully disagree that it is a hardware problem...it's that Lightroom hasn't invested in optimizing to be able to more efficiently handle new, larger camera files. It's a shame that Lightroom isn't optimizing their software to be able to run on available hardware. Last night, I took an image and just used the combination of Photoshop, and Camera RAW, and purposely made lots and lots of changes using spot healing, cloning, the brush, etc, and it was no problem. There was no lag like what happens on a photo in Lightroom. So I believe they can fix this if they wanted to. I'll try other editing software to see if others work better. Thank you for all your help - I would have much prefered to be able to get Lightroom to work!!!
