P: Cannot merge panorama after updating to 10.14.6

James,

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

Yep, have done that. Running at > 100gb free space.

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?

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.

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...

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

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

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. 

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. 

I have no issue so far doing a Panorama Merge with CR2 or DNG files using Lr8.4 and MacOS 10.14.6.
