Hi, i currently can't play mov videos in LR CC which is up to date on my iMac. Previously a small pop up with play buttons etc would appear now nothing, please help.
What exactly does happen? Does Lr freeze and you're forced to close it thereafter or you're able to perform other operations as usual?
Try disabling the GPU usage in Lr preferences under Performance tab and let us know if that helps.See Adobe Lightroom GPU Troubleshooting and FAQ for instructions.
