Lightroom Classic on M1 MacBook Air is glacial

Hi all,

I've used Lightroom for a long time, and importing thousands of files used to take maybe a few minutes at the most (on an old 2013 MacBook Pro).

I just got a new 2020 M1 MacBook Air (1 TB/16 GB RAM), loaded up Lightroom Classic 10, and tried to import 26000 files from a local folder. It took well over 30 hours. I ran a similar test, importing 500 files - it took over a half hour. I'm talking about simple jpegs from an iPhone. Default settings in the catalog and Lightroom.

I even rebooted the MBA in Safe Mode to make sure the system was as clean as possible (it's brand new, so there's almost nothing on it anyway). Still, glacial performance. Everything else on this machine is absolutely blazing fast, both network and CPU. Lightroom is clearly broken.

I've seen similar posts with no solid solutions. Is there any hope or is this the end of Lightroom for me?

Hi everybody, seven months after my original post, the native version of LrC has been released, and I'm very happy to report that verion 10.3 has fixed my issues with M1-based machines.

I've run a few basic tests, and here are the current results:

Importing 20 iPhone JPEGs:

Version 10.2: 150 seconds

Version 10.3: 2 seconds

Importing 29500 iPhone JPEGS:

Version 10.0: about 30 hours

Version 10.3: 13 minutes

Generating initial previews is taking much longer than the original basic input, but it's not holding up any work since you can just click on a an image and it generates the preview right away. The UI is very snappy.

This is exactly the performance I was expecting. (Also, the machine, a MacBook air is slient and barely warm after all that.)

Thank you Adobe, and I hope this version helps everybody out.

I'm having the same issue as well. I'm running on the the 2020 MBP M1 8GB RAM. At some point, the LR Classic 10.1.1 takes forever to open and many times it doesn't respond at all. This is very disappointing. Hopefully, Adobe addresses this issue soon.

Adobe has not provided a timeframe for shipping an M1 native version of Lr Classic. So, 'soon' is a tad optimistic.

Regarding your issues - see https://www.reddit.com/r/Lightroom/comments/kc1b7s/lightroom_classic_on_2020_m1_macbook_pro_with_8gb/ as some of the suggestions may be more benificial (I'm stretching the definition somewhat) than here

Same issue here.

Its taking me about a minute to import 1 photo on my brand new M1 mac mini. Tried restarting the mac, updating everything... still not working properly. Its horrible so far. How am i supposed to work?

How come some users are having this issues while others are not?

Interesting to hear that it's on the Mac mini as well. I've tested every update with the same results: import is just too painful to use. It only uses about 1 GB out of 16 GB of RAM during import too.

But you're right, the real question is why only some users have this issue. If Adobe actually cared about fixing this they'd probably be asking usesrs to sample the app in the Activity Monitor to find out what threads are doing what. Instead I've just gotten the brush off.

Just to follow-up for anyone who's ended up here...

I've contacted Adobe Support multiple times, and no suggestions have helped.

I especially loved their suggestion, "Install Rosetta 2 and contact Apple".

I installed LrC 9.0 and tried that too. It still took nearly 10 seconds per image to import.

I did one last test, importing 100 iPhone photos (3MB jpegs):

Lightroom 10.0 on 2020 M1 MacBook Air: 17 minutes

Lightroom CC (2016) running on 2013 MacBook Pro: 31 seconds

So... I'm giving up until Adobe releases an Apple Silicon version of LrC. Hope it's better!

i have your same machine, just installed LR classic and downloaded everything from my LR cloud....it hard for me to tell how fast slow it is, compared to LR (cloud), classic seems a lot slower but then it always has felt sluggish (which is why i have used LR )....i would not say LRclassic runs slow though...i work with hasselblad raw files and the lag i see on my external monitor should be taken care of by software optimisation....

adobe says lightroom will come in 2020, does that mean LR or LRclassic?

The Apple Silicon native version of Lightroom Classic is coming some time in 2021, according to their help article:

Apple Silicon compatibility

Lightroom (not Classic) is already Apple Silicon native right now.

~~M1 not yet supported at Adobe.~~

May or may not be supported, some confusion on that

see: https://helpx.adobe.com/lightroom-classic/kb/macos-big-sur-compatibility.html

Not a M1 owner, not a Big Sur user, in the link, Rosetta 2 emulation is mentioned.

hmm, also see:

I checked the compatibility (from that first link) before installing, and saw:

> There are no known issues specific to running Lightoom Classic 10.x under Rosetta 2 emulation mode on Apple devices with M1 processors running macOS BigSur (version 11).

Didn't seem confusing... just wrong 🙂

Unless of course the problems really aren't specific to M1 processors and Big Sur.

Are you runnung Rosetta 2 emulation?
