The app is hanging and slow on Macbook Pro M1 Max
I recently switched to Lightroom CC from Capture One, and the desktop app has been a real pain to work with. It will constantly hang, and it seems to consume massive amounts of CPU and memory. When on battery, it will drain my MacBook Pro battery within an hour of basic editing.
There is no pattern to the hanging; it can occur when simply viewing local images or when editing images in the cloud. What is constant is the hanging and overall slowness; even scrolling the edit panel can be slow and jumpy, making the whole thing such a pain to work with."
This can't be right, compared with Capture One it is unusable.
