This will have an immediate effect on the appearance of Mac windows, titlebars, sidebars, and other UI elements by using reduced transparency, and you won’t see as many animations throughout Mac OS either with Reduce Motion turned on as well, which is a new option in Sierra. Check the box for “Reduce motion” and “Reduce transparency”.Open the Apple menu and go to System Preferences, then choose “Accessibility”.

Additionally, the Mac has many motion type effects within Mission Control and elsewhere that zip and zoom around.įortunately macOS Sierra allows you to turn this eye candy off, which can result in a notable performance increase, particularly for power users who have a lot of apps or windows open concurrently. While gifs, effects, and stickers are undoubtedly fun (even though you can’t send the message effects back from a Mac… for now anyway), just have a little awareness about leaving these message windows open on the Mac.Īnd by the way, for the technically inclined people, you can test this out immediately by opening a new message window and sending or receiving a few animated gifs and leaving that chat window open… in Activity Monitor you will see Messages spike in CPU activity.ģ: Use Reduce Transparency & Reduce MotionĮye candy effects like transparent windows and overlays sure look nice, but they can also lead to performance reduction as each new window requires more system resources to draw and maintain. The good news is that the animated gifs will stop playing and pause automatically once they are off screen in the Messages app, so just send a few messages in response, or clear the chat log, and Messages app will be smooth again and whatever sluggish behavior will remedy itself. Receiving animated GIFs in particular can cause a temporary slowdown on the Mac and in the Messages app in particular, if those message windows are open and actively on display and animating as intended. Let the Mac sit turned on overnight while it’s not in use, and all indexing processes should be complete by morning with performance returned to normal.ĭo you use the Mac Messages app? If so, pay attention if you are receiving tons of animated GIFs and stickers, which can arrive in abundance from an iOS 10 iPhone user who is having fun with the new Messages stickers, gifs, effects, and other chaos that can be sent from iOS 10 Messages app. (this can also be the case with iOS 10 sluggishness, by the way). These tasks can consume a notable amount of CPU cycles as they complete, leading to blazing fans, slow performance, and Mac that feels like it’s running hot, but once the background tasks are finished the Mac will be speedy again. I know, waiting isn’t always satisfying, but it’s easy and it works! For the vast majority of users, the reason their Mac feels slow after updating to macOS Sierra is because of the reindexing features that are going on in the background. This is another process that you need to let complete in order for Photos to work properly. This can take quite a while as well, particularly if you have a very large Photos app library. It is important to just let this process complete itself, interrupting Spotlight indexing will cause Spotlight to not work properly, and it will just attempt to re-index again anyway.Īnother possible cause of a perceived slowdown after updating to macOS Sierra is the new Photos app, which indexes and scans all photos for identifiable features and faces. This can take quite a while to complete, particularly if you have a large hard drive with a ton of files.
Immediately after updating to macOS Sierra, the Mac must re-index the drive for use with Spotlight and Siri, the built-in search functions in Mac OS. Read on to learn why macOS Sierra may be running slow (some MacBook users notice their Mac is hot and fans are blasting away too), and what you can do about it.ġ: Slow Mac After Sierra Update? Fans Blazing? WAIT!
If you have noticed a performance hit after upgrading to macOS Sierra, there is likely a good reason for it, and it’s even more likely to have a simple solution. Some Mac users who have updated to macOS Sierra have felt their computer is running slower than it should be.
