I'm trying to use LR Classic 8.3.1 (fully updated) on a Mac with 32GB of memory, but keep getting the "not responding" response and when I look at Activity Monitor I see that LR is using above 126% of CPU. I don't understand how it can use more than 100%.
When it eventually starts responding, I try to use the Adjustment Brush, and it almost immediately returns to 'not responding'.
One of the files I am trying to develop is 440 Megapixels
It is impossible to use at the moment.

Hi there,
That shouldn't be happening, let's make it right.
As Lightroom Classic is using a lot of memory on the Mac, could you please try turning off the GPU option from Lightroom's preferences by going to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom and let us know if it helps?
Also, please let us know when did this start happening, after a certain update?
You may try the steps mentioned on this article and see how it goes: Optimize Lightroom performance
Regards,
Sahil

I'm having the same problem, since version 8.3.1. (Maybe since version 8.3.0)
I have GPU processing turned off.
OS is Mac High Sierra 10.13.6
40 GB RAM
108 GB free on 1 TB hd (now considering moving this to a larger drive to leave more free space, but that SHOULD be enough to work freely, shouldn't it?)
My catalog is 4.39 GB, and I worry this might be too much, but wasn't having nearly the unbearably slow performance issues on other recent versions.

Thanks Sahil.Chawla,
Turning off Graphics Processor has certainly helped, but I still get the unresponsive message and I have noticed the CPU usage going up as high as 208%.
I do not have 20% of my hard drive available at the moment, but there are 65 GB free.
This problem has been going on for months, so cannot give you a time when it started.
Thanks for your help.

Thanks for providing the information. Could you please let me know the operating system you're on?
Also, could you try updating Lightroom to version 8.3.1 via the Creative Cloud desktop app and let us know if it helps?

I'm using MacOS Mojave 10.14.5 on an iMac 27"
I will also add that I have just tried to send an image to Photoshop from LR, and Photoshop responded by posting 'Could not complete the command because of a program error.' LR was using over 298% CPU.
I am already using version 8.3.1

Sounds like you are too short on hard drive space on the drive your catalog is located in. The key figure being less than 20% remaining.

440 Megapixels? might be more efficient in PS.
