Hi there! Thank you for reaching out! I'm really sorry to hear that you've been experiencing delays in your workflow. Here are a few things you can try to improve the performance:
1) In Lightroom Classic, go to Catalog Settings > Metadata and uncheck Automatically write changes into XMP.
2) Clear Caches in both applications:
- For Lightroom, go to Edit > Preferences > Performance > Purge Cache under Camera RAW Cache settings. You can also try increasing the Cache size.
- For Photoshop, go to Edit > Purge > All.
3) Reset LrC's and Ps's preferences: Make sure to use the manual method to reset preferences

4) Make sure Lightroom and Photoshop have Full disk access on your Mac. Here's how you do it: How to give Full Disk Access to Lightroom Classic on macOS - Adobe Product Community - 12913413
-The process is the same for both applications.
