Lightroom Classic

After the recent update to Lightroom 15.3, I am unable to import photos. No previews are generated and when I try to import any files, the import process hangs and I have to force-quit. I am using a brand-new MacBook Pro with an M5 Pro chip and 24 GB RAM on Tahoe 26.4.1. I am importing from a CFEXPRESS card via a reader that I’ve used for 2 years. The photos are from a Nikon Z8, both NEF (raw) and JPEGs.I have turned off the GPU acceleration, turned off “Ignore Suspected Duplicates”, deleted the preview cache, and uninstalled and reinstalled Lightroom and it still will not generate previews or complete the import process. Additionally, when I try to quit Lightroom Classic, the quitting process hangs and I get the pinwheel of death and have to force-quit. Where can I go to find an answer to this problem?

I have accessibility to LR, but my Windows dosen't support the latest version of LR. Meanwhile, Adobe does not provide old versions of it, which makes it impossible to download.My PC lost some files so it can’t update operative system of Windows, even by downloding update assistant from Microsoft. On the other hand, I don’t know how to get the old version. 

Now that Adobe has moved the DNG converter out of LR Classic… In my LR Classic catalog containing over 100,000 images I have thousands of CR3 images that now apparently may need to be converted to DNG’s.If I run the DNG Converter app on CR3 images already in my LR catalog, do the converted files replace the original CR3’s in LR and retain the keywords and LR processing history, etc. as it used to when the DNG conversion was integrated in LR?Or… Does the DNG Converter just blithely convert the CR3’s to DNG’s obliterating the keywords and history and requiring them to be re-imported as new files?I’ve been unable to find an explanation.

Can the Keyword Suggestion automatically not show values already shown in the visible Keyword Set? I tag all my photos extensively but Keyword sets don’t show a lot of values. I use both Keyword Suggestions and a Keyword Set effectively as two Keyword sets. Unfortunately Lightroom often shows the same values as what is visible in the Keyword Set that is selected. This duplication reduces the usefulness, adds delay and extra clicking. See below 

See the attached screenshot...the LIBRARY GRID button doesn't work any more..it did up to a couple of days ago. I’m not aware I changed any settings to stop it working, though that will probably turn out to  be the answer! A few minutes ago I updated Lightroom Classic to 15.4.1 but that made no difference. I am running Lightroom Classic on a MacBook Pro, Tahoe 26.5. 

Hi,I wanted to ask about the new masking improvements in Lightroom Classic 15.4, because I have noticed a behavior that seems very relevant for people photographers.The new Select Subject is clearly much more refined on edges. In many cases, the mask is more detailed and more accurate than before. However, in some images with a model sitting or lying on a sofa/bed, Select Subject does not select only the human subject. It sometimes includes parts of the environment close to the model, such as the sofa, bed, cushions, or similar elements.This is a serious issue in a people-photography workflow. If the goal is to mask the model, a mask that also includes part of the sofa or bed becomes basically unusable, even if the edge refinement is better.On the other hand, Select People is semantically more correct because it identifies the human subject, but in my tests it still seems to have less refined edges than the new Select Subject. So, at the moment, there seems to be a strange trade-off:Se

Since updating to 15.4.1, LR Classic (on Mac Tahoe) is stuck trying to sync 74,000 images, even though I only have 4,400 images in albums marked to sync. I’ve tried both deleting and rebuilding sync data, but the problem pops right back up.Anyone seeing this? Ideas?

I have a relatively new (almost 1 year old) Mac mini M4 and I can't get it to download the update, 15.4.1 that is showing in my Creative Cloud. I starts downloading but extremely slowly and eventually grinds to a halt.Is the problem with me or is it a general issue? I’m currently running LR Classic 15.3.My Mac mini is an M4, 32 GB memory,Mac OS TahoeStorage 304.33 GB available of 994.66 I read a suggestion that I run Creative Cloud Cleaning Tool but though I have downloaded it I can’t seem to open it. Not sure why?

tried eveything… none was working. any help?

I have lost my LR cat file. Not sure how this happened but I have tried everything. I had a corrupted external SSD that I had been using to store photos but LR Classic is on my laptop. I realized it was corrupted because I couldn't write to it. Luckily I could still get all the files off it. I moved everything to a new external HDD and reformatted my SSD. I am pretty sure my catalog was housed on my laptop but even if it was on the corrupted drive I had moved everything off it before reformatting. I have the catalog preview file but not the actual catalog anywhere. I’m pretty depressed thinking I will have to start a new catalog, import thousands of photos and have lost all the edits.  Is there any hope for my situation?   

At first when I tried to synchronize a folder in Lightroom Classic, Synchronize said there are 424 photos to import, but then it did not import any. I am on release 15.3.1, which I am told is the latest, and Windows 11 Pro. I have installed all operating system updates and GPU updates. I have also restored preferences in LR Classic. At the top level of my catalog, selecting All Photos, I have tried looking for specific files that are not getting imported, and LR can’t find them, so they can’t be there somewhere else in my catalog. I have never had this problem before. I have quit LR several times, and it sometimes would tell me that there was a corrupt file, so I deleted those files from my system.Now when I try to synchronize, it says “importing files at their current location”, but nothing ever happens. When I ended the import, it told me that 2 files were unsupported or damaged. The files are type .ARW, created by a Sony A1 camera, that I have had no problems with in the past.I have

Steps to reproduce:  Try to Open LRCError Message:  Lightroom encountered an error when reading a catalog file and needs to quit.  Light will attempt to dianose the problem the next time it lauches.Tried: Uninstall and reinstallTried:  going back to previous versionTried:  Alt upon opening and tested integrityMy nerves are at the breaking point….I need it to work again.

Issue summaryOn my Mac, Lightroom Classic 15.3 becomes unresponsive after some period of normal use. I have to Force Quit it. After that, Lightroom Classic can relaunch, but RAW files can no longer be opened properly. I cannot guarantee exact reproduction steps every time, but the issue has happened multiple times in 15.3 and has not happened for me in 15.2.1 on the same machine.Environment- Lightroom Classic: 15.3- macOS: 26.4.1- Apple Silicon Mac: M1 MaxWhat I can confirm- This issue started after updating to 15.3.- It happens after some time of normal RAW workflow use, not immediately on launch.- Once Lightroom hangs, I have to Force Quit it.- After relaunch, RAW files still cannot be opened properly.- Downgrading to 15.2.1 on the same Mac resolves the issue.  Relevant lines from the report:Process:      Adobe Lightroom Classic [12526]Version:      15.3OS Version:      Mac OS X 26.4.1 (25E253)Exception Type:      EXC_CRASH (SIGTERM)Signal Number:      15Publisher Process Name:      

Import multiple photos, select one photo and rate it 5 stars. When another photo is selected it will be rated 5 starts as well. This makes culling a challenge and effects workflow speed.

I've been using the Ai supported denoise feature, and while it works well, I receive an error message and I have to run it twice instead of once. The program makes me do it over again before export, and both processes take up two hours each. The error  says to reach out to customer support and post here. I use a Lenovo, and recently this has been adding more unnecessary time to my workflow. I’ve made sure everything is up to date, and to my knowledge, my computer is capable of running the program and operations.

When LR Classic opens I can see all of my folders but the previews are all grayed out as the screen shot shows. I tried uninstalling the application and reinstalling it but the problem still happens.

System:Lightroom Classic 15.3.1 running on Mac mini M4 Pro 48GB 650GB spare storage.Catalogue is on the internal Mac mini SSD. Problems:This problem occurs frequently:Open up LRC, Edit three or four images in Develop module. Proceed to next image, but the image in the Develop module doesn’t change, or there is a grey panel. Shut down LRC - Writing Metadata changes into XMP…sticks at 29% and makes no further progress. So I have to force close LRC. I have tried disabling GPU etc. Any suggestions please? Thanks Richard

Why is Adobe Light Room so slow? Simply scrolling through the film strip can take seconds between images. Newly added images can take up to 30 seconds. Stitching is super slow to create panoramas compared to other programs like PTGUI. Simply selecting the crop tool causes the LR screen to go grey and then refresh. Everything I do in LR is slow and I’m constantly waiting on it.   

when I try to use the replacement tool with the Generative AI option I get the message: “Generative Remove FailedWe've encountered an issue and can't complete your request at this time. Please try again later” this keeps happening no matter how much later I leave it

RAW file exported as jpeg (5 meg) in Lightroom Classic V15:3:1 with content credentials applied I see no CR pin on the image as suggested in Adobe help videos.

Lightroom Classic 15.3 intermittently becomes completely unresponsive (permanent hang, requires Force Quit) when opening RAW images in the Develop module or when generating previews during import. A macOS `spindump` captured during a live hang shows the cause is a **self-deadlock inside the Camera Raw engine** bundled with Lightroom Classic 15.3.The operating system's own deadlock detector flagged it. The spindump header reads:- `Deadlocked: 1 thread - Thread 0x11612a "Queue Processor - NegativeQueue_1"`- `Blocked by Deadlock: 3 threads - "Queue Processor - OpenNegativesForDevelop_1, _2, _3"`The deadlock graph points the thread **at itself**:`Deadlock: ... thread 0x11612a "NegativeQueue_1" -> thread 0x11612a "NegativeQueue_1"`The deadlocked thread's call stack runs through AgKernel (Lua) into CameraRaw, ending at:`...

I run LrC 15.3 om a Mac Powerbook. I purchased a new WD 24TB hard drive when my old 12TB filed up, and moved my photo files to it. I also just returned from a trip where I imported several thousand pictures as well. When all migrating and importing was done, the catalog seemed happy. All pictures were recognized. Since then, pretty much every day for the last four days when I open a collection a number of pictures have the dreaded exclamation point indicating that the picture can’t be found. For the past three of those four days I’ve reimported those pictures from a 2TB travel drive and reedit the pictures. Yesterday evenoing all was well. This morning I have the same problem. I haven’t moved to 15.4 because I didn’t want to compound my problems with a new catalog and new version. Any thoughts or suggestions would be greatly appreciated. Thanks.Marty
