I got a new MacBook Pro. I downloaded my presets to it and now every time I hover over presets light room goes nonresponsive and I have to force quit it. I have deleted my presets and reinstalled them. What else can I do? Do I need to uninstall Lightroom and then install it again?
Sorry that Lightroom freezes on your MacBook Pro when you hover over on to your presets.
Which version of Lightroom are you using and what is your computer's OS?
Does the app freezes while accessing a specific set of presets? Would you mind deselecting the option "Use Graphics Processor" located in Lightroom's Preferences > Performance menu, then relaunch the app and see if it helps?
Also, even if you reinstall the app, a preference file will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.
1. Close Lightroom.
2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.
3. Overwrite the Preferences when prompted by the dialog.
