If you are using an older version of macOS, you should upgrade to the 2019 version before using this course. This video shows how to confirm that your computer is able to run the 2019 version, then run the upgrade.
- [Instructor] In this movie I want to talk about what it takes to upgrade to macOS Catalina from a previous version of macOS, but you should be aware some types of applications that work in older versions of macOS will not work in Catalina. So before you even decide if you want to upgrade you should check something, and I'll show you that just a moment. But before I do anything it's important to make sure your files are backed up before running a major upgrade like this. It's rare, but there's a slim chance that something could happen to affect your files. Next you should make sure that your computer is able to run macOS Catalina. For that you should take a look at this page which shows a list of computers that are able to run Catalina. If you're not sure which Mac you have, then you can go to the System menu, that's this button up here that looks like the Apple logo, that'll open up this menu, go to About this Mac where you can see exactly which computer you have and then you can check that list to make sure your computer compatible. Also on this screen I can see which version of macOS I'm currently running. I'm running version 10.14, which is macOS Mojave. So my computer is compatible, but what about my applications? As I mentioned a moment ago there's a big change in Catalina, it no longer supports 32-bit applications. These are applications designed for an older type of processor. They're less common these days, but you should check your applications to see if you have any. So still here on this screen, I'm going to go to this button labeled System Report, scroll down on the left side and find the option for Applications. And this just shows you some information about all the applications you have on your computer. And I want to look at this column labeled 64-bit. If your applications are 64-bit, they're going to work just fine in Catalina. If it says no here, then it's a 32-bit application and it will not work after you upgrade. So the easiest way to check this is to click on the column header here, which sorts all the yeses and noes together. If you don't see any noes then you can click on this column header again to reverse the sort. But you can see I have three applications that are 32-bit, they have the no next to them. Now a few of these are not a big deal. InkServer and quicklook, these are part of macOS and those will be upgraded when I switch the Catalina, but I do have an application here called TextWrangler, and this could be a problem. This is something that I use it for my work and if it doesn't work in Catalina, that is an issue. If you have an application like this and it's important for the work that you do, you may not want to upgrade because this application is not going to work in Catalina. Now in this case there are newer applications that do the same job, so I could switch to one of those, but unfortunately you need to research that for your specific situation. Sometimes upgrading to a new version of the application is enough, but this could be a reason for you to just not upgrade to Catalina. You may need to wait until there is a newer 64-bit version of the application before you upgrade. Now that's just one example. With all of this in mind I'm going to do the upgrade, so I'm just going to close all the windows that I have here. Now one way to get to the upgrade would be to go to System Preferences. So we'll go back to the Main System menu, that little Apple logo, and I'll choose System Preferences, then I'll go to the category for Software Update. And you may see the upgrade for Catalina available right here. Now if you do not see it here, you could go to the App Store. I have the app store here on my dock, so I can open that up, I can go to the search bar, search for Catalina, and I can see it's right here. Now before I can install something from the App Store I do need to be signed into my Apple ID, there's an option down here on the bottom left to Sign In, and there's a movie later in this course on the App Store in particular. But for now I'm just going to close this and I'll use the option right here in System Preferences. So to get started I'll click Upgrade Now, and this is going to take some time to download. And this really depends on your internet connection speed, so I'm going to skip forward in time so we can see what it looks like after it this has been downloaded. Whether you start this from the App Store or System Preferences, when the download is finished you'll see a window like this. When you're ready click Continue, then you'll see the Licensing Terms. You may want to scroll through here and read it, but when you're ready you can click Agree and Confirm here. Next is going to confirm that it will install the upgrade on my main system drive, and that's fine. If you have multiple drives on your computer with bootable installs of macOS, then you should choose the drive that you want to install the upgrade on. But that's a little unusual. I'm just going to hit Install here. Now in my case, I get this window here where it's showing me a list of those 32-bit applications I have on my computer that are not going to be compatible with macOS Catalina. If you've checked this and you're confident that you're going to be OK in Catalina without being able to run this application, you can continue, if not you might want to cancel. But I'm going to continue. I'll put in my administrator password and click OK, and now it will start the process. Now the time that we see here on the screen is only the first part. In a few minutes the computer will restart and after restarting it will continue with the installation process. And this is another step that will take some time, so once again let's skip forward. When the installation process is finally complete, sign in to your account as normal. Then you'll see a few set-up screens, so just go through those prompts and answer the questions that you see there. When this is all finished you should confirm that Catalina is installed. So we'll go back to that System Menu, the menu with the little Apple logo, back to About this Mac, and I can see I am now on version 10.15 macOS Catalina. So now I'm all done with the upgrade, I now have macOS Catalina on this computer.
