Hi wider team
I'm on a MAC OS 10.10.4 and want to uninstall not needed older version of Lightroom (5.7.1).
Is that just dragging the Adobe Photoshop Lightroom 5.app to the waste basket ?
Keep a copy of the LR 5 Catalog in case you ever wish to revert to that version. Lr 5 will not be able to work with a LR 6 catalog.
