P: Slow UI when using Mac and Custom Display Profile

Is there someone from Bill's family here? Because, confusion, repetitions ad nauseam, reality deny, etc, could be the signs of a medical emergency.

Projection at its finest.

Your ignorance is only exceeded by your arrogance. 

...Still banging on about hardware when everyone, including Adobe, has stated the problem lies in the software. Give yourself and everybody here a break from your nonsense. 

...And of course you have solid evidence that "at least half of the Lightroom V10 issues reported on this forum would have been prevented"?

Of course not, it's just your dogmatic and unsubstantiated 'belief' but at least it represents a slight shift towards putting the blame where it belongs - Adobe. So well done for that.

This post is being merged into an existing thread for better tracking and response.

Like Windows started doing a couple years ago, it could check for the TRUE minimum hardware and software requirements and not the joke requirements published by Adobe. I've had Windows updates automatically delayed by as much as 6 months because of hardware in my system.

Not perfect but it would work well if Adobe would take the minimum requirements seriously. At least half of the Lightroom V10 issues reported on this forum would have been prevented. 

I have been on chat for 2.5 hours with Adobe help.  After much trouble shooting, Version 9 works perfectly with Big Sur.  The issue is the preview speed on Version 10.1.1.  Jan 13th, there was an update to LR Classic and it totally messed up the preview speed in the program.  If you have this issue, reinstall version 9 LR Classic.  The issue is not with the graphics card or anything else with the computer, as all other programs work fine.  Hopefully this will save you hours of aggravation.

You mean the installer should import some images, edit them, check the slider speed, export them, check for OS crashes, etc. etc. Wow, that's a smart installer! 😜

Really Bill.  Enough.  Most posters are NOT using hardware that is outdated. Your rejection of the evidence is the sad part.  Not to mention unhelpful and distracting.

keep on dreaming, Gerhard

When has this ever happened ???
