Since upgrading to OS 10.14.6, Lightroom Classic (8.3.1) cannot merge (21 frame) panoramic images. Just sits there forever and does nothing.

Just following up on this. So it's any large panorama that Lightroom Classic has an issue with since upgrading. It's like it won't use the full CPU (like it did before) to render it. Rendering panos in Photoshop works just fine (and uses the full CPU); it's just a Lightroom Classic issue -- almost like it's only using a 1/4 of the threads available to it.

Good morning Ray,

I have had the same problem and I stumbled on a change (I hesitate to call it a solution) that got things going again: I changed the name of the files. I know. It is completely ridiculous to think that that pano s/w sulks until it sees the file names changed, but it has worked for me more than once. All I can say is try it and if it works we'll ask Adobe how is it that these two things could possibly be related.
Cheers,
Koro

It may be a corrupt cache or application state, or directory damage. Or it might be Lightroom, but you need to rule out that it’s a MacOS issue with your system first.

Please give your Mac the "once over"! Run the free Onyx (https://www.titanium-software.fr/en/o...), reboot. (In Onyx just run almost everything in the Maintenance tab, deselecting things you may not want deleted, like Launch Services . Hit the "Options" button and deselect more stuff like Cookies & Other Site Data, Browser History, Form Values, etc.), then hit Run Tasks. After it's done it will ask for a reboot.

If that doesn’t fix it run Disk Warrior if you can ($120), (https://www.alsoft.com), reboot. If you can’t do Disk Warrior, at least run First Aid from Disk Utility. Also just doing a "Safe Boot" can clear out caches (restart, hold down shift until you see "Safe Boot" on the screen, then reboot normally.

If that doesn’t work try launching Lightroom from your other (admin or test) account, with a new catalog, as a test. Does it run OK? If it does it may be a corrupted preference in your Username/Library folder. Check The Lightroom Queen site for instructions on how to reset your preferences (https://www.lightroomqueen.com).

If changing the file name works, then it may indeed be a cache problem. You could start by purging the Camera Raw cache (in the Preferences).

That's my problem, too. Reinstalling Lightroom is no solution, a clean and fresh install of 10.14.6 is no solution... Adobe's customer service seems to know the problem but decided that this is an Apple-problem because something changed in MacOS regarding memory caching.
Can't work any more with lightroom. Apple does not allow downgrades, no matter what. My system is right now completly useless.
Wondering what happens when 10.15.0 will show same caching behaviour... Lightroom will not be useable then, too.
Exporting RAWs is also impossible, LR freezes. Sorry, but this is really a desaster!
LR needs an update!

If you hire a REAL Mac tech he/she can downgrade you, but it’s many hours. Do a web search in your area.

You can easily downgrade your OS using a previous Time Machine backup. That said, hopefully Adobe recognizes the problem and solves this sooner than later.

Lightroom Classic 8.4 was released yesterday. Please try installing this update and seeing if you still have issues with the panorama merging. So far, as a team, we've been unable to reproduce what you are experiencing. 

If, after the update, you are still seeing issues, then we need to get some detailed information from you regarding your OS version, free disk space, etc.

This reply was created from a merged topic originally titled Lightroom Classic 8.4 hangs when creating panoramas.

Lightroom Classic now hangs when creating panoramas. The issue started while on 8.3 but I have now updated to 8.4 and still have the same issue. LR Classic been reliable for months but I now can't create any panoramas within Lightroom. The same images will merge within Photoshop (if I merge the HDR's prior to Photoshop) or PTGUI, but I prefer to stay within lightroom as it creates an ARW file. Depending on the file set, the preview step can hang, or it  can hang during merge. HDR still merges ok.

Guys, a long shot, but can we get the contents of Help menu > System Info please? I can't reproduce it either, and I'm wondering if there's a hardware element that's shared across your system. Also, the camera used to capture the photos might offer some extra clues.

Another FYI (and I know this is non-specific, but...), until the last couple of days (i.e. the time I upgraded to 10.14.6) I had no real lag or performance issues with LR. However now in general use I get frequent spinning wheels and general slowdowns when just browsing the catalog etc. So that potentially backs up the theory re hardware related issues.

It's not limited to a MBP - same problem here on a Mac Mini 2018 / i7. It's not limited to LR but freezes also CameraRaw in Photoshop as soon as you work with DNGs. Call the CameraRaw-team...

For the record, my issue was specifically with any panos that were 21 frames -- same thing > DJI (Mavic 2) Pro drone. James, what might be helpful for the Lightroom team is to shoot them a Dropbox/Google Drive link to the DJI pano frames so that they can test it.

Thanks Ray... I can fire them the shots no problem if they need. However for me it's "anything". I've tried with a number of different DJI (same drone) shots, variable shot counts, plus Sony Camera shots. Perhaps tried around 10 different pano's shot over the last couple of days and nothing will merge.

I'm using a Canon 5Ds. Having problems with anything regarding dng-fileformat. Exporting cr2 is no problem, exporting dng freezes. Creating HDRs does not work, creating panoramas does not work. Working with cr2 is no problem at all.

Set up a completly fresh 10.14.6, installed only Lightroom - same problems. LR freezes as long as dng-file format is created/exported.

Free disk space: 200GB

As far as I can see LR uses only one core while processing dng

Thanks for your input on this issue so far folks. Any thoughts on a solve? To recap and add clarifications...

a) Panorama creation impossible, either hangs at the merge step or the preview step (can't determine a pattern but it seems related to image set). Affects both Panorama and HDR Panorama.
b) General operations definitely slower, frequent spinning wheels while browsing library, trying to enter develop module, etc (having never seen any in the past 12 months of heavy use - 20,000 images per year). 
c) Issue occurs to files from multiple devices (Sony Camera and DJI Drone), across multiple (all) image sets. Panoramas created in the past using Lightroom will now not recreate from the same source files. 
d) Lightroom 8.4 & Mac OS 10.14.6.
e) HDR merge does work (but anecdotally seems slower).
f) The same files will merge using PTGUI and Photoshop (but Photoshop won't create a dng pano output).
g) Have copied my sys info above.
h) I've already tried purging the camera raw cache and disabling the GPU acceleration and various other combinations of memory allocation, performance settings etc.

Just at the time Lightroom should have sped up with 8.4, for me at least it's become virtually unusable, possibly in relation to 10.14.6.

I wouldn’t mind trying a set that’s failing for you, see if I can reproduce it on any of my machines. If we can reproduce it on demand, there’s a much better chance of it being fixed quickly. Dropbox or www.wetransfer.com to uploads@lightroomqueen.com would work.

James, roughly how long did that take you previously to merge? And it's an HDR Pano, right? It's been pegging 100% CPU for about 30 minutes so far, using about 10GB of my 16GB of RAM, and it's made it to about 40% of the way across. Is that what you're seeing?

If LR shows the beach ball when you try to work on while creating the HDR or pano then yes, that's what we see. In this case it's also not possible to quit LR in a regular way. Try to export a dng as tif - does it work? Here it took a week ago 20-30 seconds to merge 5 shots of my 5Ds to one HDR. Now it takes 15-20 minutes.

Hi Victoria, it seems you are seeing exactly what I'm seeing. Before the last few days, to merge around 15 HDR Pano Shots (yes it's an HDR Pano) from the drone in the past I'm used to it taking around 3 mins max on my MacBook pro. The Sony shots take longer, but they are bigger files. I've previously merged 70 shots from the Sony on this MacBook and it took around 20 minutes.

Thank you for your input here Victoria. Yep that's what I saw, maxed CPU for around an hour (and very hot laptop) and stuck at around 40% ish, on a file set that I know in the past would have taken only a couple of minutes to process. Unfortunately, I don't have a Mac Pro to hand :)

...btw, I have also tried converting the bracketed shots to HDR prior to attempting to create the panorama (in this case, creating 5 DNG's from the 5x3 Brackets). The "HDR" DNG files will create (although, anecdotally, slower than I'd expect them to), but the panorama will not create from those 5 files either.

Now that you are able to reproduce the problem, what's coming next? Is there a chance for an update within the next days? Has Adobe tested this issue with Mac OS 10.15? Please excuse that I'm quite impatient - would like to finish my jobs here but without HDR and panoramas it's not possible. Don't really want to create a non-RAW-panorama with another software but if there will not be a solution available for this problem very soon I fear that I have to because I have to finish the jobs...

> Now that you are able to reproduce the problem, what's coming next?

Having been able to reproduce it on a specific machine, we're a lot closer to Adobe being able to reproduce too. When they can, they can then start figuring out the cause, and then a solution. Then it'll go through testing and then get pushed over to the downloads team to get an update out. Realistically, probably be a few weeks.

BTW a few weeks are far too long - started a tif-export 8 hours ago (14 cr2-images), system has not finished it by now! LR is unusable!
EDIT: ok, now it's finished... maybe the system was in stand-by because I turned off the screen. Despite this I would really appreciate it if someone official will prioritise this.

I walked all the way with the support incl. a screen sharing session (case ADB-8411867-Z0D5). Wondering why the support knows more than the official LR-Reps here. Two support members talked about a changed method of memory caching used in 10.14.6 which makes it incompatible to LR. Apple says that Adobe got 10.14.6 months before public and had enough time to react to changes made with this update. And now nobody from the official side can reproduce it? It's really obvious that something went completely wrong.

I'm very jealous of your situation Robert. I've come to rely on the DNG output from Panorama's in Photoshop & Lightroom. However, for example, I just tried to use the "Auto-Stack" feature in Bridge (a feature which requires the software to parse the DNG file) and Bridge crashed. This is indicative of what I'm finding now across the whole Adobe Stack which shares Camera Raw.

Like I said,  "so far".   Hopefully it will keep working.   : ).   In a post above you said you would upload some of your pano photos for others to try.  I haven't seen a link.  The pano I tried was 11 photos from a Canon 5DMark2.  I also tried other smaller ones and they all merged fairly quickly.  Some wouldn't merge with "perspective" but that happened previously for some panos.

Hi Robert, yes I sent some files to Victoria on the dropbox link she posted, but the point is, it's all panorama files, from more than one capture device, including any of the many panorama's that I've previously successfully merged in the past using the Lightroom.

I'm as certain as I can be that it's nothing to do with the files or devices...

The files you sent, were they native DNG capture or were the other that were converted to DNG?

A new business opportunity : ). BTW, I’m using a 2015 27” retina iMac with I7 processor and SSD that has full graphics acceleration enabled if that helps narrow down the issue. macOS 10.14.6

As far as I can see LR uses 280% of CPU (3 cores) while creating the HDR-preview but falls back to nearly 100% (1 core only) when really creating the DNG, with or without graphics acceleration. Seems to be a problem with the CPU, maybe (Intel core i7 3,2GHz here).

Inquiry, in relation to Apple MAC OS, and possiblility of CACHE methods/locations/whatever (mentioned above)

Would/Does dleating all existing CACHE files (all, not just Aobe) help??

And a link on how to safely do that??

Under the concept of junk, clutter, trash, can the Apple CACHE files be causing grief, I assume most never ever clear that stuff out

Hi David, I've cleared all cache, trash, etc etc, including using Onyx to run a full system clean. It free'd up lots of drive space and made my mac a bit faster in general, but has made no difference to Lightroom, Photoshop or Camera Raw.

forget about clearing the caches. Even on a fresh system it does not work.

Inquiryy/Note 2

Do not forget to clear out your Deleated folder (collects dust) and Download folder (really need that stuff) as they eat up disk space. And lack of disk space can foul LR up
