Please try the suggestions already made in this thread.

This did the trick for me, thanks! If anyone else on a new M1 Pro / Max is having issues with slow-to-load image previews when importing in Lightroom Classic, try this. 

Haha, sure, I know it's not as bad as "have you tried to re-install macOS"...that's why I used a wink after "tedious task"...but I shall give it a try if I can't get a better solution soon.

Thanks for the clarification and advice. After 35 years of dealing with these types of issues, I am not a fan of the old "de-install/re-install" trouble-shooting method, as it rarely makes a difference, in my experience, but for the sake of not wanting to come across as thick-headed, I shall give that a try in the morning (I am in Berlin, Germany).

The world of Apple Silicon has been amazing, so far, but maybe your hunch is right, and the incessant Adobe updates rhythm has gunked up some shared files that could cause these types of issues.

If anyone else has any wisdom/guesses, let me know, otherwise, I'll report back after that tedious task 😉

I do have a memory app installed that I use frequently to "free memory", or is there a macOS/Terminal process that you recommend I initiate?

I was hoping that a native LrC is in the stars and available soon. I am one of many who love LrC for all my organizational and processing photography needs. Apple Silicon is a revelation, and I hope that we can all get a bit more life out of this venerable application.

Since I haven't used my MBP 2018 to work in LrC since I got my MB Air M1, I'd say it's safe to say that they were not using the same version of Big Sur.

But your questions make me wonder whether you suspect Big Sur of being at fault, here?

Sorry for the late reply. I didn't see any update notices to this thread.

Well, when I say that nothing has changed, I meant that nothing *major* has changed since I last spent time in LrC to import and work on photos. So, the version of Big Sur probably did change from minor point update to another (I think I was still on 11.3 when I last did a smooth LrC session, and now I am on 11.4).

It's just that I usually important mostly timelapse sequences of many hundreds to a few thousands of photos per sequence, and see them pop up with thumbnails almost immediately...for a few thousand, I sometimes do have to wait for an hour+ to see the previews build complete.

But when I imported just 78 photos the day I made my original post and then watched as each thumbnail took 30secs or so to build, it just felt all wrong.
