Lightroom Classic CC: Getting Slow on macOS

The past few updates for the standalone (7.x) software for Lightroom has been progressively getting worse. In the latest update, it was stated that systems with 12gb of RAM or more would be running faster in a variety of areas. However, I would disagree as my device has 16gb of Ram and now when I load the software a majority of the time it says (Not Responding) in the loading phase - something that did not happen prior to the update. Once the software is open the photos take longer to load in the library menu.

Also, I have noticed my workflow pace has decreased with these updates and editing takes longer than before. Two clients have already complained about the timing of my work when the only factor that contributed were these updates. It seems once LR CC was released the standalone software began to diminish. 

I hope more attention to LR Classic is given or I will sadly have to switch editing software to one that can meet my editing needs.

I don't understand which version of LR you are complaining about. Are your running Lightroom CC, Lightroom Classic CC 7.2, or Lightroom 6.14 the standalone version? These are the latest updates of the three current versions of LR.

It's clearly LR Classic CC 7.2 as it's the only one that got a speed update with such specifications and mentioned in the bottom.

Lightroom "Standalone" from the subject line refers to versions 6.0 - 6.14.  I am updating your message to reflect the version and avoid the confusion for others.

I'm having similar problems. I have 8GB of RAM on my Mac, though it has an SSD, and I'm paying a mighty price (damn it, Apple). Develop is HOBBLED. I've restarted LR multiple times, and the computer a few times, as well. Even with Smart Previews built, working with 30PM 5D4 files:
  • Switching between photos takes 2-3 seconds
  • Painting on an image with a simple adjustment brush (+3 exposure, .1 size) takes upwards of 5 seconds to render.
  • Opening the left panel from its hidden state triggers multiple spinning beach balls.
  • When moving between images, 3-4 seconds to load a sharp preview.
  • Zooming to 2-1 and back takes about 1 second each time.
  • Panning when zoomed is jerky and unresponsive.
  • Selecting the pin of a previously-made brush adjustment takes 3-4 seconds.
  • Closing an adjustment brush takes 1-2 seconds.
  • Converting to BW and back takes as long as 5 seconds.
I'll add more as I find them. This is embarrassing, Adobe.

System details:

MacBook Pro (Retina, 13-inch, Early 2013)
8GB 1600 MHz DDR3 RAM
3 GHz Intel Core i7
Intel HD Graphics 4000 1536 MB
MacOS 10.13.3 (17D47)

Adam,

If you go to Preferences>Performance is the Use GPU checked or not?  What happens if you uncheck it/ check it? Do you still see the same elapsed times?

At five years old, with only 8 GB of ram your system may struggle with some aspects of Lightroom - particularly if you are shooting large-megapixel files.

Hi Rikk,

My understanding is that GPU acceleration doesn't work on my machine, so I've left it off. That said, I checked it, and it now recognizes that I have the Metal graphics engine. I gave it a test just now, and it seems to be as slow or slower.

These problems did not occur in the 7.1 release; indeed, it was much faster than it has been.

By and large the user community is reporting better performance with 7.2 than 7.1. That has been my experience as well. 

There is a chance you have something else amiss.

Have you:

Reset Preferences?

Uninstalled 7.2 completely and reinstalled?

Hi Rikk,

I'm glad to hear the community is generally benefitting from the upgrade. I just reinstalled it completely, and the problems persist. I'm reinstalling 7.1.

Edit: After downgrading the problems have largely gone away.

Did you reset your preferences? They survive an uninstall reinstall?
