If some of the hardware included in your device doesn’t work after you have updated to the macOS Sierra, it might be because it’s outdated.
Apple is actually part of the Bluetooth Special Interest Group (Bluetooth SIG) that makes sure the development of the Bluetooth are within standards. Thus, Apple keeps up with it every single time.
macOS Sierra supports only the latest Bluetooth hardware. Thus, if yours is outdated and cannot be updated, you have to replace it with something new.
What the solution? You have to downgrade to El Capitan. Or, you have to upgrade your hardware.
This one is not actually a problem. It’s actually a feature of macOS Sierra. Apple usually wants to get rid of outdated stuff like Java, Flash, Quicktime, and Silverlight.
When you give up these outdated plugins, you are given a faster and better browsing experience---enabling you to enjoy the new HTML5.
macOS Sierra Safari will ask you if you would like to turn on the plugin if you come upon a site that uses these outdated ones.
What you can do is the state to Safari if you want to turn on the plugins once, every single time, or cancel it (and actually don’t ever return back to the website that utilizes Flash and other outdated plugins).
There are times when applications don’t work in macOS Sierra. They simply won’t open or they crash altogether. The reason for this is actually simple. It is not compatible with the said operating system.
Why is this so? Well, maybe the developers haven’t updated the application to make it compatible with macOS Sierra. Or, you, yourself haven’t updated the app to its macOS Sierra-compatible version.
What’s the solution? Well, you have to check out if there are updates to these applications. You can visit the official website of the app to check if they have issues with Sierra compatibility.
Finally, you can actually check out if there’s an alternative app you can use to replace these non-compatible applications. If you wish to uninstall these outdated apps, don’t simply put them into the trash.
Use iMyMac’s Mac Uninstaller to completely wipe it off your system.
Here’s how to use it step-by-step:
Choose from the modules on the left. Select the module “Mac Uninstaller”
Click Scan to scan all applications in your device.
Wait for the results to display.
Select the application you want to remove.
Wait a moment to complete.
A lot of people experience reduced battery life on macOS Sierra. But the problem isn’t usually with the operating system itself. It might be because the battery is really old.
Or sometimes, it might be because there are a lot of applications running in the background. Other reasons might be insufficient RAM and a disk drive that is filled with files and folders (not enough disk space).
If you think your macOS Sierra experiences reduced battery life, you can actually check out the problem on your Mac device.
Step 1 - Launch Activity Monitor and check out what actually runs on your device currently.
Step 2 - Check the Autorun. These include applications that automatically run when your Mac device starts up. Check out if there are autorun applications that are unnecessary.
Then, remove them from actually running when the Mac device starts up.
Step 3 - If nothing really helps you, you should downgrade to a lower operating system, El Capitan.
It’s better to have a long battery life while using the older operating system than having the new one but your device shuts down after only a few hours of using it.

*If you want to go back to previous versions, you can utilize the backup from Time Machine. Or, you can go to the Apple website to download it.
