Should I do anything

before upgrading?

Two simple things: clean up your Mac and then back it up.

Check Your Hard Drive

macOS Catalina approaches disk storage in a new way. Compared to previous versions, it favors cleaner hard drive for better performance, so first check what’s taking up your space before upgrading.

Clean Up Your Mac

The fresh macOS needs a fresh Mac. It’s recommended that you remove large and old files from your disk and install macOS Catalina on a cleaner hard drive. The easiest (and fastest) way to free up your storage is by running a scan with CleanMyMac X. It cleans out:

System junk

Unused apps


Browser junk

Large & old files

Broken downloads

Adware extensions

User caches & logs

Unused DMG installers

CleanMyMac can find as much as 62 GB of junk (based on average scan results). But besides cleaning, it speeds up your Mac with maintenance scripts and manages memory-draining apps. Get CleanMyMac X now and run a scan to see how much junk you can clean up.

Download CleanMyMac X

If you have OS X version 10.8, download the previous version, CleanMyMac Classic.

Back Up Your Mac

And now that your Mac is clean, you should definitely back it up. Why? You never know what will happen when upgrading your operating system. Plus, it’s just good practice to back it up every so often, you know, just in case.

  • Go to yourSystem Preferences folder.
  • Select Time Machine.
  • “Select Backup Disk…”
    You may need to first choose to “Set Up Time Machine.”
  • Choose where you’d like to store your backup.
    An external drive or an Airport Time Capsule is good.

After you’ve chosen the drive, click the Time Machine icon in the upper bar and select Back Up Now. This initiates the backup.

That’s all. Happy time with macOS 10.15 Catalina!
