Now that iOS 13 and iPadOS has dropped, the next major Apple upgrade will be macOS 10.15 Catalina, which is likely to land this month, and could land as early as this week. So, this is a good time to prepare your Mac for the upgrade so as to avoid nasty hiccups like data loss, and to make the process go as smoothly as possible.

Here’s my macOS 10.15 Catalina upgrade action plan.
The simple answer here is that if your Mac can run macOS 10.14 Mojave, it can run Catalina, otherwise you’re out of luck.
Here’s a complete list of Macs that can run macOS 10.15 Catalina:
What to know what Mac you have and what your version of macOS it is running? Click on the Apple menu and select About This Mac. The Overview tab will show you the Mac you have and what version of macOS it is running.
Before you start installing operating system upgrades, updating apps en-masse, or freeing up space for the upgrade it’s a good idea to make a backup to protect you against something going wrong (or protection against you doing something that isn’t so clever).
I like for a backup to be the first thing I do because it gives me peace of mind. If you have a Time Machine backup routine in place (or one that uses a tool such as Carbon Copy Cloner or a service such as Backblaze) then it’s worth checking to see that this is working and actually making backups. In fact, it might not be a bad idea to have more than one backup, you know, just in case!
Whatever you do, don’t assume that you have a backup!
The macOS 10.15 Catalina download is about 7GB and will require about 20GB of free space to install.
Don’t have enough free space? You can either go about manually moving and deleting files, or let a tool like CleanMyMac X do the heavy lifting for you.
Catalina is the end of the line for 32-bit apps, so if you rely on any then you either need to upgrade (which may mean a paid upgrade), wait for the developer to get their act together and release a compatible version, or find an alternative.
Want to know if you are using any 32-bit apps? Here’s how to find out.
It’s a good idea to make sure things are upgraded so as to reduce the scope of things going bad. It’s not absolutely essential, but every little helps.
You will need this to log in to your iCloud account.
You can always enter it in at a later point, but either way it’s a good idea to know where this information is.
Here’s what I will do on upgrade day:
