Speed up Your Photography in OS X by Reducing Motion Effects
We all know about motion effects in iOS , but it turns out that they are hidden in OS X. OS X Daily indicates that the Photos app has this feature, and you can improve performance by turning it off.
Open Photos , then go to Photos> Preferences and select the General tab. Tap Reduce Motion to turn off various animations so you can make your photos less cumbersome to use. If you feel like your Mac has been running rather slowly lately, you can try disabling a few other animations .
