SLOW Converting after Lightroom Classic 15 Update

Troubleshooting and Bugs Lightroom Classic CC
1

Hi I updated to the new Lightroom Classic 15 yesterday and converted a roll of 36 exposures and it took FOREVER. It took around 20 minutes instead of 5. Anyone else updated and have the same issue?

I’m running Negative Lab Pro v 3.1.1 on Mac OS 15.7.2 with a MacBook Pro M4 Max with 128GB of RAM.

I had to downgrade to Lightroom Classic 14.5.1 and now it’s back to normal.

Not sure if NLP needs to be updated to work with Lightroom Classic 15 or if there’s a bug with Lightroom Classic.

Thank you.

I can only compare to my Windows 11 installation. NLP is 3.1.1 and Lightroom Classic is 15. Conversion speed with my roll is as fast as ever.

Interesting, wonder what my issue is. Thank you for replying!

Interesting. Running 3.1.1, LR 15, OS 15.7.1 it takes my 2016 intel Mac Book Pro with 16Gb ram 1m30s to batch convert a 37 roll.
