I have a new iMac and now LR stalls out if I try to export a slide show. My old MacBook Air works perfectly with exporting. anyone have ideas on why this could be? My LR version is a duplicate of what's on the Macbook Air.
My OS on the iMac is totally up to date.
Can anyone suggest a fix?
Are you getting any error message while exporting the slideshow from Lightroom? also, you may turn off the GPU from the Lightroom preferences and check if that helps.
Open Lightroom > Edit menu > Preferences > Performance > Uncheck the GPU > Restart.
Mohit - thank you for taking the time to reply. The actual issue turned out to be simple. When I got my new iMac, I followed Apple's suggestion and bought a cable and used the Migration software. LR doesn't like that. I only needed to uninstall and reinstall LR and now it works perfectly.
Great, thank you for sharing the fix.
