Lightroom Classic

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:      

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. 

This post applies to Camera Raw and Lightroom Classic. Dust Removal is no longer in Early Access status and can be found in the Remove edit panel for Camera Raw & Lightroom Classic. Dust Removal helps remove distracting spots in an image that may be caused by dust on a camera's sensor and is also effective on dust on the rear lens element. Once enabled, your image will be scanned, and any detected dust spots will be automatically removed using Content-Aware Remove. For refinement, you can select one or multiple spots to delete or refresh. Batch removal is also supported; simply select the "Dust" checkbox under "Remove" in the copy settings dialog.Please note that scanned negatives are not in the scope of this feature at this time.  Dust spots on scans tend to be located in the focal plane, with the negative and very sharp, while sensor dust is typically positioned out of the focal plane and therefore not in focus. Scanned negative dust typically appears as white spots on a darker b

Lightroom Classiv v15.3 (on Mac OS Tahoe) has a problem importing photo files that have a pipe symbol - a | symbol - in the XMP field dc:subject.Lightroom apparently has a problem interpreting the pipe symbol, and then hangs, seemingly indefinitely until the import is cancelled, while showing a high level of CPU usage. This hanging seems to take place at the end of the import process for this photo.The pipe symbol is used by Lightroom to separate levels in the keyword hierarchy within the Hierarchical Subject XMP field.  Having pipe symbols also within the keywords doesn’t seem to be a problem with the Hierarchical Subject field - at least it doesn’t interfere with importing.  Also the pipe symbols in the Weighted Flat Subject field don’t seem to cause a problem with imports.Attached is a sample file that hangs when being imported into Lightroom.  Of course, a problem file causes a batch import of photos to fail, with some number of files correctly importing until Lightroom does to pro

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.  

This post applies to Lightroom Classic and the Lightroom Ecosystem products. Camera Raw feedback can be found here.   Generative Remove makes it easier to remove unwanted objects and distractions with a simple gesture, even on complex backgrounds. For more accurate results, be sure to include the object's shadow in your selection and/or expand its size.    Detect Objects uses AI to find the objects underneath a brushed area. The masked areas will now appear larger than the Early Access version of this feature. You can also circle objects for quicker selection now.    We have also updated the spot selection experience to make it easier to manage variations, switch the fill type, refine the selection area, or re-generate as needed.    Batch updating is also now supported for Generative Remove spots.    Try out the latest updates and share your feedback with us here.

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

tried eveything… none was working. any help?

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

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 am trying to tether my Sony A7V to Lightroom Classic on my MacBook Pro.  When I try Lightroom just gets stuck trying to detect my camera.  I was able to connect my camera using Imaging Edge Desktop so I know it's not an issue between my camera and computer or my USB-C cable.  Both my camera and Lightroom are completely up to date.  I’ve tried following every tutorial I can find but I haven't found any specific to using the A7V.  My menu titles are all slightly different and in different spots than older versions of the camera so I’m not 100% sure I have everything set up right on my camera.  Since it is working with Imaging Edge though, I assume I am.  I’ve also tried deleting Lightroom Classic preferences on my Mac which I saw in a few posts with similar situations but the files I was supposed to delete did not exist.  Could it be something to do with my camera being a relatively new release?  I have only started being able to open RAW files in adobe in the last couple months becaus

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?

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:`... (CameraRaw) -> std::mutex::lock() -> _pthread_mutex_firstfit_lock_slow -> __psynch_mutexwait`with the kernel annotation: `(blocked by turnstile waiting for th

Installed this and my tethered camera setup no longer works.  It appears to work as before, but no images are transferred.  Canon R1, Windows 11.  Anyone else having tethering issues?
