First and foremost, Siri’s coming to Mac. This is great news for everyone who’s already used to her help on iOS. Then, there’s Watch unlocking for Mac, there’s one-click Apple Pay, tabs in apps, and cross-device copypasting. Just to name a few.

Version, Space, and Memory Requirements for Sierra


If you’re running an OS version like Lion (OS X 10.7), you’re looking into a lot of upgrading before getting Sierra. To upgrade to Sierra from, say, Mavericks, you’ll have to consequently upgrade to Yosemite and then to El Capitan first.

Check Your Mac OS for Sierra Compatibility

These OS versions can upgrade to Sierra:

  • OS X Mountain Lion v10.8
  • OS X Mavericks v10.9
  • OS X Yosemite v10.10
  • OS X El Capitan v10.11

Here’s how to find out which OS version you’re running now:

  1. Click Apple icon in the top left corner.
  2. Choose About this Mac.
  3. There you have it, in capital letters.

RAM iconRAM: 2 GB (preferably 4 GB)
Sierra is pretty lightweight, so you only need 2 GB or RAM to upgrade. Cool, eh?


Disk space iconDisk space: 8 GB of free space on drive.
In the same About this Mac menu select "Storage" tab. In front of the multi-colored bar, you will see the phrase, "X.XX GB free out of XX.XX GB." If you don't have at least 8 GB of free space, you should delete some old files.


Before you update Mac OS, don’t forget to:

Clean up your Mac

This is essential if you want a fast and effortless update, and glitchless work of your new macOS. And it’s also pretty easy. To give your Mac a cleanup, you need to get rid of system junk, uninstall extra apps, and clean some old caches. If that sounds like a lot of work, you can get a Mac cleaner like CleanMyMac for the job.

  2. Launch it.
  3. Hit Scan to find all the extra files you can delete.

That will give your Mac a basic system cleanup, but CleanMyMac is going to come in handy after the update as well. It monitors your Mac’s health, helps you speed up the system and remove unnecessary apps (Trashing doesn’t fully uninstall apps, by the way).

Back up your Mac

This is basic common sense before any Mac software update you’d like to undertake. Why? Well, because sometimes updates happen less smoothly than you’d like them to. To make sure you have all your information and files saved up neatly, you need a backup. To back up your Mac, you need to activate Time Machine.

  • Open your Applications folder.
  • Choose Time Machine.
  • "Select Backup Disk…"
    Note: You may need to first choose to "Set Up Time Machine."
  • Choose where you'd like to store your backup.
  • Both an external drive or an Airport Time Capsule fit.

Backup your data with Time Machine

  • Switch the toggle on the left, from "OFF" to "ON." Right beneath the name of your storage device, you'll see "Oldest backup," "Latest backup," and "Next backup" — Your backup will begin within 5 minutes. To speed it up, click the arrow clock icon next to the Date & Time at the top-right of the menu bar and select "Back Up Now."
