What do you need to know before updating?

Before you dive right into the updating process, you should know and consider a few things and understand that updating to a Beta update might bring a few risks with it. Let’s take a look at what you need to know before updating:

Backups – Backups are a necessary process of updating; they help you securely upgrade or downgrade to an OS and helps keep your data secure if you face any issues. So, always keep a backup handy and stored in someplace safe in the cloud to make the overall process much more seamless.

Compatibility – Know that the new update won’t be supporting the whole list of Mac devices, and here’s a list of the supported ones. However, if you don’t have a device from the list below, then you’re out of luck.

  • MacBook Air (early 2015 and later)
  • MacBook Pro (early 2015 and later)
  • MacBook (early 2016 and later)
  • Mac mini (late 2014 and later)
  • Mac Pro (late 2013 and later)
  • iMac (late 2015 and later)
  • iMac Pro (2017 and later).

Note: Monterey is very M1 specific and brings a lot of features that are M1-only. Features such as Live Text won’t work on Intel devices, and keep these in mind before updating.

Stability issues – The Beta update will also have stability issues as not all apps would work perfectly with the OS. You should make sure that you’re going to be affected by it to move on with the upgrading process.

Risks of updating –  There’s always going to be a risk that you may end up screwing something up or making a mistake, and well, this risk is something that you should be aware of. You can brick your device or make it unusable, but the chances of doing so are slim at best.

Cleaning up junk from your Mac – Removing junk system files and unneeded apps from your Mac will help speed up the upgrade and downgrade process. Not to mention you can free up a massive amount of storage space that you can use for any other thing. So, if you back up your data with Time Machine, cleaning up is an excellent idea because Time Machine creates lots of copies which can take up a lot of storage, so the less stuff on your device, the better and more seamless the upgrading process.

How can you make a backup?

Making a backup of your Mac should be your first step and is an overall easy process to get started with. All you need to have is an external storage device and your Mac. Follow the steps below to get your Mac backed up.

TimeMachine Backup

Time Machine backup – Time Machine is the inbuilt backup service from Apple and can help you backup all your data to an external storage device. You can do this by:

  1. Go to Apple menu > System Preferences, then click on Time Machine.
  2. Click on “Select Backup Disk” and let Time Machine do its thing.

Note: Time Machine backs up your data with automatic hourly backups for the past 24 hours. You can also make daily backups for the past month and weekly backups for all previous months.

iCloud backup – You can also manually store all your data to your iCloud account by simply dragging and dropping all your essential files. Just head on to the and drop all your files in and start iCloud backup.

Third-party backup tools – Finally, you can also use some great backup tools from fro third-party developers to help you make a backup reliably and seamlessly.
