2. Clean up your Mac

  • Delete unnecessary applications

You can use the free tool App Cleaner & Uninstaller from Nektony. It allows you to delete all of an application`s service content and remains. By the way, this recommendation is preferable not only for macOS Sierra installation. Clearing your hard drive from time to time helps your Mac run faster.

  • Clear cache and junk files

A special app called ClearDisk can help you. Clearing all of the cache, logs and language preferences may free up much of your memory space.

  • Check your drive for big and useless files

This can be easily done with an app called Disk Expert. It will take 5-10 min depending on the size of your hard drive.

  • Find and remove duplicates

It’s simple to find duplicates with Duplicate File Finder. The app allows you to find all duplicate files: photos, videos, music, and even similar folders.

  • Find and delete unneeded hidden files

A free app Funter allows to find any file, including hidden ones. It searches in bundles and packages and offers to delete unneeded data.


3. Make a backup copy

There is a risk that you may lose some important files while upgrading. So, we highly recommend to backup before upgrading. Use Time Machine for this.

Any reliable cloud (iCloud Drive, DropBox, etc.) is suitable to backup the files. Just check that you have enough data space before doing so.

Now you are ready to install macOS Sierra. After all these preparations, feel free to go to the App Store and download the new operation system. It will take from 30 minutes to an hour to install macOS Sierra.

It is important to mention, that clearing all cache and junk files from your Mac allows to avoid further issues. For instance, some users complain about a slow Wi-Fi connection after macOS Sierra Beta update. If you are faced with such a problem, follow the next steps to solve the problem:

Turn off Wi-Fi connection  Create a folder on your desktop with any name Open Finder window and use a shortcut Command + Shift + G in a “Go To Folder” window type /Library/Preferences/SystemConfiguration/. Find  these files’ names there:

  • com.apple.airport.preferences.plist
  • com.apple.network.identification.plist
  • com.apple.wifi.message-tracer.plist
  • NetworkInterfaces.plist
  • preferences.plist

The next step is to copy these files to the folder you have created and delete them from the SystemConfiguration folder. Then restart your macOS Sierra and turn on the Wi-Fi. (Resource – Fixing Wi-Fi Issues)
