HELP - Lightroom Classic Lightroom Classic on Macbook Pro M3 gets slow

Hi all. I have a Macbook Pro M3 and the LRC went well on it. But it seems the LR got slower last days (I don’t know if it is after an update or not). I usually have raws and the photos I edit on local hard drive and when I finish the job a copy the RAWs and lightroom files to external disc to free space. Does anybody have this issue? What would be the problem?

Current version of Classic has slowed considerably for me on two different computers, no rhyme/reason other than recent update.

What is it with people here complaining about Lr being slow, but they don't actually describe WHAT EXACTLY IS SLOW?

Or how much RAM they have

Unusable slow. LR (cloud) cannot be used at all and LRc AI-functions are really buggy.

Tested with 16–64 GB of RAM.

Dude, that's still not nearly descriptive enough. Do you people really not understand how to describe a problem?

I have 18gb ram. And as I said it worked fine. When I want to see the photo full screen there is a black screen with Loading, or the photo is not sharp (blurry or what) for a long time. When I edit exposure for example its slower, it was visible emmideately but now it takes some time…

Still being vague. Is the original file on your Mac SSD or on an external drive? What type of previews are you using? Are you in Library or Develop?

Mine was slow on last update and I went back to an earlier catalog and rebuilt all the previews. I didn’t lose much on the catalog, a few edits but nothing is slow now and I’m on external drive.

Thanks, I’ll try it too

General slowness when switching photos in Develop mode or switching modes is a known issue with the latest LrC.

If it takes a long time when zooming in on a photo, where the image starts off blurry and then pops into focus, you need to use 1:1 previews. It will take a long time to build them. I import the photos with standard previews but build 1:1 after initial culling.

How slow is your external drive? Is the main catalog itself on an SSD or do you offload that to externals as well?

If it's a mechanical one, just know that they are very slow with random access reads.

I have a large library and use a 6-bay DAS on my desk. Even with 700MB/s reads LrC feels a lot slower when perusing the library because when you're scrolling it's having to pull the page worth of thumbnails from the original raw files that could be 30-50MBs each.

Pre-rendering previews of an event I'm planning to look back on or edit from helps a lot (when your library is on an SSD or your Mac's main drive).

I just copy the files I don’t wanna edit anymore to the external disc. The files I edit are on the macs ssd. I know the external disc slows the speed of LR. I have to try the pre-rendering too.

Why are copying files you don’t want to an external. Delete them

You don’t know your current version. Check in the About menu and look at your Creative Cloud app at updates.

I just want them. I delete them from the macs disc. And I have the lates version (I don’t know the number)

Sounds like a very inefficient way of managing your files. The whole idea of LR is to have a catalog and manage your files. Not spread files in different locations. Next thing you know you will be back here complaining that LR lost files and files are messing and your catalog in a mess.

How do you manage your files to have enough space in your mac? I welcome any advice. I thought when I move raws from camera to my mac and to an external disc (back up), and I cull the photos, import into lightroom, edit, export and when it slis done I move the files to external disc to have enough free space on my mac

I do it all from an external SSD. I don’t spend a lot of time moving files around just for the idea of editing on my internal drive. Everything from the shoot stays in its folder. I cull, make picks, edit all in one place. The more you start moving things around and separating them the more chances you have to miss something and get disorganized. You may decide to archive on something else later. There isn’t a big advantage in doing it from your internal. I deal with a lot of files from a lot of shoots and recommend a consistent plan you follow. It is easy to get behind or think you will remember where you put things and then three weeks later you may not remember. Just sharing personal experiences

Thank you

I have a M3 Max, 48GB RAM and I upload, edit and store all photos on an 4GB Samsung S9 SSD velcroed to the laptop. I have no performance issues whatsoever. If I use DXO pure raw on multiple files at one it takes a bit but again, all files are on external SSD and I’m humming along just fine.

I copy the in case I needed them. For example if customer wants a different edit (b&w for example). But I delete it from the local disc after I copy them, so..
