Hi all, I'm having Lightroom slow down when importing photos after switching from M1 chip to M2 chip. The mac in question is the MacBook Pro 14" 16GB 1TBSSD Does anyone have a solution?

You haven't mentioned where you're importing the files from (e.g. camera connected via cable, card reader, direct from disk). Likewise, you haven't mentioned what version of macOS was installed on the M1 MacBook Pro and what version is on the M2 MacBook Pro.

Macbook Pro M1 – MacOS Monterey 12.3.1

Macbook Pro M2 - MacOS Ventura 13.3

Here aswell Lightroom is very slow, lagging and freezing a lot on M2 64GB 4Tb...My previous Intel was faster...:-(

Sounds like I have the same computer as yours and Lightroom is lagging badly. Even zooming in on an image is painfully slow. My 6 year old intel chip mac is way faster.

Same here on my M2 Macbook Pro with Lightroom, my 2019 intel is just the same performance....

Have you checked to see if the importing settings are the same on the new Mac, or have unintentionally changed? For example, in the Import dialog box, if Build Previews was set to Emebdded and Sidecar on the M1 Mac, and now they are set to 1:1 on the M2 Mac, it will probably take longer for an import to complete.

Hi, I have the same laptop - MacBook Pro M2, 14", 16GB, 1TBSSD, and I have the same problem - Lightroom is slow as a snail. It starts OK, but it freezes after 40-50 RAW photos. After freezing (which takes about 10-15 sec) it works a bit, but after a few pictures, it freezes again. It is tough to work like this (especially if you have more than 1000 photos to process). If I close the Lightroom, everything starts again - the first 40 images are fast, but after that...
In addition, while the computer is frozen, other programs also do not work properly. Can anyone help please?

What edits are you applying to the photos. Masks, brush, spot heals, etc. The more information you can provide the better.

It would also be helpful if you upload a screenshot of the Activity Monitor 'Memory' tab when the issue next occurs. Make sure that you do NOT close LrC before capturing the screenshot. I've attached an example of what I'm asking for.

There are relatively few Mac users reporting the issue and none (zero) to date have provided a single word of explanation as to what they were actually doing to the 40-50 photos. So, I'll ask you for the same infor I asked earlier - see post directly above yours.

Example: These are the adjustment i make to the photos. And after a few 30-50 pic (few because the imported photos number are 1800 from an actual project) it slows down realy bad.

Above crash report indicates that you're using Rosetta Emulation. LrC has been Apple Silicon native since 10.3 (June 2021). I appreciate that you were told to use Rosetta, but that advice clearly came from someone who was trying to find a straw to clutch on to (I'm being polite). Best you revert to Apple Native rather than x86 emulation.

The crash itself appears to be related to a batch process using Apple's CoreML (Masks and AI heal are just two areas that LrC uses Core ML).

Yepp I have switched back, but these crashes are coming with and without rosetta...:-)

This type of Mac "had to be" the fastest of all...as the commercial say. but it seem not. And Lightroom keep bugging aswell by importing photos from the SSD and it dont open the library folders just after a restart... it is non sense....

Same issue here....

I haven't even started editing; it even freezes if I'm sorting the photos

You appear to be using a 'Window Manager' and it's using a big chunk of memory (and likely other resources). If it's a third party 'Window Manager', then try turning it off to check whether that helps with your issue. It should certainly ease your memory pressure.

THats the "WindowServer"? How can i turn it off?? Is it an app?

Report · May 30, 2023

Your list has both WindowManager and WindowServer…the difference is very important.

Do not force WindowServer to quit. WindowServer is a core macOS service that handles all windows in all applications. If you force WindowServer to quit, you will be kicked out of your macOS account immediately to the login screen, without a chance to save documents or quit applications.

The WindowManager process is what you should look at more closely. It’s running within your user account (according to the User column). From what I can tell from brief web research, WindowManager is associated with the Stage Manager app that comes with macOS 13 Ventura. If you are using Stage Manager, you might try turning it off and see if the situation improves.

I was replying to the post by @artursinipalu The screenshot provided shows both 'Window Server', which is expected and 'Window Manager'. Typically, the 'Window Manager' that's part of macOS uses 10's of MBs of memory. However, look at @artursinipalu screenshot and you'll see the 'Window Manager' is using 3.5GB. I have no idea why 'Window Management' would need that amount of memory. On the other hand, the 'Window Server' will often use upwards of 1GB and more when multiple windows are open.

Report · May 30, 2023

I just made a software update to Ventura 13.4, and now WindowManager is about 20-30MB.

I hold my eye on it, thank you.
