Before you can enjoy all the new goodies from macOS High Sierra, you must answer the question: can your Mac run macOS High Sierra? Nervous? Don’t be, as the specs look quite promising. How promising? Well, you’ll be able to upgrade to High Sierra even if you own a Mac as old as 2009. Sure, the hardware might cause you some slight drawbacks and refuse to run all the features, but overall you should be able to enjoy the big refinements. Things look even brighter when it comes to newer version of Macs, which should support the new operating system without any problem whatsoever.
Go for a system cleanup and fast backup
The first step towards a clean install, is a drive format. But act with caution! Before you do anything drastic, make sure you cleanup and backup your Mac to keep your important files.
Start with a system clean-up. Okay, that’s actually an euphemism for: delete everything you don’t need, throw away any duplicates and erase all the useless data.
Don’t know how to do that exactly? Check out How to clean up your Mac for a detailed and easy way to perform a thorough cleaning.
There are going to be some important files you will want to keep. Be it files, documents, photos, movies or other apps, you’ll want to create a backup for them. Where? That’s up to you. You can choose either iCloud or any external storage device with enough space.
Now it’s time to wipe your Mac clean. But you did perform a Mac backup, right? Good! Then you can format the drive! Here’s how:
Go to Applications > Utilities and click on Disk Utility. From here, select the drive and hit Erase, as you select Mac OS Extended (Journaled) as the format type.
Before you start new life with the new macOS, get equipped with a couple of backup and maintenance tools. They will save you should something goes wrong. The good solutions are Get Backup Pro or Disk Drill.
And the last thing before we start. A new OS needs a fresh Mac, so trim down the fat on your system. Use an app like CleanMyMac X to remove all system junk, large hidden files, and old apps' leftovers.
