RAM usage on Macbook M1 with Lightroom

Hi all!

I'm new to the Adobe Creative Cloud. I bought a subscription for the photography plan last month, and I installed Photoshop and Lightroom (the cloud-based one).

Long story short my Macbook Air M1 (which is not the fastest but also not the slowest laptop on the market) is severely slowed down when I use Lightroom. It happens when I have multiple masks on the same photo and I'm adjusting some settings: it doesn't freeze completely, but it significantly slows down my laptop, causing delays of several seconds between actions.

My system monitor shows about 80% usage of the RAM, while the CPU and the GPU do not work at all: they reach about 25% and then drop down, and then go up again, but they never stick to a stable level. They seem to just give to the RAM all the job.

My M1 Mac is currently running MacOS Sonoma 14.5

Lightroom is running the 7.4.1 version and Adobe CC is on 6.0.3.207

Please let me know what I need to do in order to make it work fine.

Thanks in advance to all those who will reply!
