Macbook Pro M1 8Gb bad performance in Lightroom and Photoshop

I just returned my recently purchased M1 Macbook Pro, because it was not able to run Lightroom Classic and Photoshop 2021 smoothly. Pretty much everything inside those two Adobe apps running inside Rosetta was laggy, stuttery, slow. Things like switching between two photos in Develop module, or just selecting the crop tool could take up to ten seconds to load up. Adjustment sliders were very unresponsive. Photoshop could freeze for seconds when simply selecting a layer. Brush would freeze and lag constantly. I've never before seen the beachball so often. Wacom tablet would lag worse and worse the more workload you would put on Photoshop. Switching from Lightroom or Photoshop to Safari to browse would take a couple of seconds, and Safari would continue to work slow and spin the beachball here and there.


After watching so many rave reviews that also specifically praised how well Adobe apps run in Rosetta, I was dumbfounded. I thought there was something wrong with my unit. After running every possible performance benchmark software I could find, I got exactly the same scores that all the reviewers did online. I can't imagine how that could be possible if I had a faulty unit.


Unfortunately I did not try to reinstall the os before returning, because I was convinced there was nothing wrong with the computer. In hindsight I should have done that. But again, benchmarks were fine.


Anyone else having these issues?

OP here with an update. I have since bought and returned another M1 Mac, this time a Macbook Air 8gb. It seemed to run better overall, with none of the frequent beachball lags. Lightroom Classic was still very slow (5 second delay with crop tool etc.), but it seemed to me that the much worse problems I had with the previous Pro were some glitch, and I should have tried to reinstall OS, apps, everything.


After coming to the conclusion that my new M1 Air 8gb is working correctly, I figured it's just too slow because of the 8gb RAM. Seems to me that the memory swap really isn't as fast as everyone is saying it is. So I got the 16gb Air, and wow! It's worlds apart. Absolutely everything is faster, and everything is so clearly affected by the doubled RAM. Just as you would figure in any normal computer. From general OS responsiveness to Lightroom and Photoshop, all of it works much better (just a 1 second delay with crop tool in Lrc). I can't understand why not a single reviewer has pointed this out.


I think that if you're having bad performance in any 16gb M1 Mac, there's something wrong and you should start by reinstalling all Adobe apps, and then maybe Mac OS. If you have excessive beachball in regular Photoshop use with any 8gb M1 Mac, there might be something wrong, and you need to reinstall stuff, but don't expect much from Lrc.

I've got a Mac mini M1 8gb ram/256 SSD. I find performance with Lightroom Classic generally fine but not as good as some of the you tube reviews would suggest. And probably not as good as a higher spec intel Mac.


I'm working with a 250,000 image catalog and previews located on the mini's SSD. I don't use 1:1 previews (or only occasionally) just let it build standard ones. There is a 2 or 3 second lag loading the higher resolution preview (generally 24 or 42 mp files) when switching images and zooming to 100%, tools and sliders are generally instantaneous/fast except for the spot correction tool that can get laggy.

I'm using a 32" 4k screen, usually scaled to look like 2560x1440, MacOS scales down from 5120x2880 to do this, which also uses resources, I sometimes switch to native 4k resolution, this may improve performance a little but text is a little small for me so usually stick with the scaled option.


I had recently moved from a windows pc and had rebuilt my entire catalog a few months ago on a 2015 2.9ghz i5 8gb MacBook Pro as found the imported windows catalog glitchy. The M1 is considerably faster than the old MacBook Pro.

Performance is better if the lr window isn't full screen, and for a test I created a smaller catalog of 1000 selected images, again performance was better, but not enough to give up the convenience of having everything in the same catalog.


I'm hoping that when LR Classic has a native version performance will improve, but I'll probably see what the M1 successors are like and consider this M1 mini a temporary option.

I am having the same issues with Photoshop where it stutters after applying an effect (rolling beach ball) and often times crashes. I have the M1 Mac mini with the standard 16 GB of memory (they don't offer more and we can't install more ourselves) and 256 SSD. I use it mostly to scan and retouch photos and can't seem to work with more than one image at the same time without it stuttering and crashing. The images range from 2 to 50 MB. I did not have these issue with my previous 2011 iMac desktop running High Sierra. I switched to M1 Mac Mini (least expensive option until they came out with the new iMac) because I needed to upgrade Final Cut Pro but haven't tried working in it yet to find out if this is only happening when using Adobe software. Reports say that we have to think about memory differently when it comes to M1. Either we all have faulty Macs or Adobe hasn't done a very good job with upgrading their software for the M1 chip working with a limit of 16MB of memory. Right now Photoshop for me is a memory hog.

I am experience the same issue in Photoshop MacBook Pro M1 2020 (2 weeks old). A layer converted to Smart Object and I am attempting to use Wrap is taking 10 seconds or more delay. It’s very frustrating because I thought this is going to be a big change for me as I am a freelance designer that uses Windows OS for so many years and Adobe CC is working just fine there. All YouTube Reviews sucks then if they are hiding the real problem in Photoshop. I hope this will fix right away because it’s frustrating. Love you all
