Apple always recommends its users downloading macOS install file from Mac App Store for security reasons. It is safe and easy. But the actual downloaded file is not an dmg file. Instead, it is an app called Install macOS Catalina, which is used to make the upgrade from current macOS to Catalina. For a clean install, it is better to download the dmg file and make an installer USB.

Note: Make sure to back up your Mac prior to installing macOS Catalina.

Step 1: Go to Mac App Store and search macOS Catalina. Then hit on 'Get' to download page.

Step 2: Doing this will open System Preferences followed by the section of Software Update, where you will find MacOS Catalina ready to download. Hit the option saying 'Upgrade Now' and download MacOS Catalina on your Mac.

Step 3: Next, macOS Catalina upgrade will ask for system reboot. Complete the process and install macOS Catalina on that computer.

Downloading macOS Catalina Install app works fine on my of newly devices but it could be problems for old Macs even it is officially supported by Catalina. If this is the case, then you have to patch the OS and install Catalina again. However, you need find a third-party app to do the dirty work. We will talk about this in Part 3.

Part 3. Download macOS Catalina 10.15 Installer with macOS Catalina Patcher

Although it may appear easy to try out the conventional approach of downloading macOS update in Software Update, there are a few known issues on old Macs shipped in 2013 or earlier, meaning the download progress can not be completed successfully. That's why macOS Catalina Patcher tool comes into help. This patching tool makes the job even simpler for installing macOS Catalina on unsupported Mac models.

However, the file size of these updates differs depending on the Mac device you are using. That means the downloaded update might not necessarily be the full installer version. For instance, if you wish to keep the installer file as archive for further application, or use it to generate bootable flash drive, this file size won't be sufficient.

Fortunately, with macOS Catalina Patcher tool, you can simply download the entire update of macOS setup from Apple's servers. Let's check out the stepwise instructions of how to use this software tool to download the macOS Catalina DMG.

Step 1: Download a copy of macOS Catalina Patcher from this link.

For iPhone and iPad users who still connect their devices to a Mac for syncing and backups (and there are a lot of people who still do this), there are changes in the latest version of the Mac operating system. In macOS 10.15 Catalina, the iTunes app is gone.

Now you use the Finder, similar to how you see a hard drive or a server. Here’s how to use your device in the Finder and how to back it up.

Your iOS device in the Finder

When you connect your iPhone or iPad to your Mac using a Lightning cable, it will appear in a Finder window. In macOS Catalina, your device is in the left column in the “Locations” section. (If this is the first time you are connecting the Mac and iOS device, you will be asked to pair the two on the Mac, and you’ll have to trust the Mac on your iOS device.)

When you click on your iOS device in the left column, the window will fill with some information that looks a lot like the info you used to see in the iTunes app.

1. Connect your iPhone or iPad to your Mac using a Lighting cable.

2. Open a window in the Finder (Command-N).

3. In the Locations section in the left column of the Finder window, look for your device and click on it.

4. Information about your device should appear in the right side of the window. Click on the General button near the top of the window if it’s not already active.

  • If you want to encrypt the backups on your Mac, check the box for “Encrypt local backup.” You will need to create a password.
