Way 1: Apple menu → System Preferences → Software Update. Choose Apple menu on your Mac, then choose System Preferences. Then click Software Update and Hit on the Update Now button next to the macOS 10.15 Update. After you do this, an installer will appear in span of a few seconds. Apple has released macOS Catalina 10.15.7, a minor update that fixes a few bugs in macOS, including an issue with automatic Wi-Fi connections, one that could prevent files from syncing with iCloud Drive, and a graphics problem with the Radeon Pro 5700 XT in the most recent 27-inch iMacs.

1. Macs using OS X 10.7 through 10.10 must first upgrade to OS X 10.11 El Capitan before updating to macOS 10.15 Catalina. Go to the OS X 10.11 El Capitan download page to get it. Open the System Preferences menu and select Software Update.
2. Unlike watchOS 6, macOS Catalina 10.15.1 is a slightly bigger update and not only brings AirPods Pro support for Mac, but also includes over 70 new or updated emojis as well as new Siri privacy.
3. Launch System Preferences. Click on Software Update. Let the page refresh for a few minutes and you will see the new macOS Catalina 10.15.6 update available for download. Hit the download button.

A fresh start is not a challenge in the Mac universe. Quite the opposite, getting a macOS upgrade every September marks a surge of new features and functionality enhancements—all coming right your Mac’s way.

Apple introduced the perks of macOS 10.15 at the 2019 WWDC, and lots of features have been tested and discussed since then. A dual monitor available with the Sidecar feature, the Photos app update, and a brand-new iTunes made the show this year. Lots of features migrate from iOS, the others appear for the first time. If you’re wondering why Catalina is worth an upgrade, check the full list of killing features here.

Traditionally, there are two stages at which you can try macOS Catalina before it’s officially released. Starting June, there’s a developer beta available, and about a month later—a public one.

Take all your apps to macOS Catalina

Get Setapp, a suit of Mac apps that strengthen your macOS. When you decide to upgrade, your curated apps will travel with you.

A few things before you switch to Catalina

Your to-do list for the upcoming upgrade:

1. Ensure your device is compatible. As usual, there’s a limited number of Apple devices that support macOS 10.15. It’s not too different from what we had last year, but take a look anyway. Sometimes the reason why you can’t upgrade lies on the surface:

   • MacBook Air (2012 or newer)
   • MacBook (2015 or newer)
   • MacBook Pro (2012 or newer)
   • Mac Pro (2013 or newer)
   • Mac mini (2012 or newer)
   • iMac (2012 or newer)
   • iMac Pro (all models)
2. Say goodbye to 32-bit apps. Mojave was the first macOS to stop admitting 32-bit apps to the App Store and the last to support them. In Catalina, you’ll have to limit your Mac to 64-bit applications only. Once you install macOS 10.15, you’ll be warned about 32-bit apps not working on your Mac any longer. CleanMyMac X will help you quickly filter applications by 32-bit and get rid of them:
3. Backup valuable data. When we’re too excited, we tend to rush things. Remember though, that a new macOS means a new start—wiping away the past. To keep your data safe, create a backup before upgrading. You can use Apple’s in-built Time Machine or more advanced tools like Get Backup Pro if you want a bootable backup.
4. Clean up your Mac. You need to free up some space for your new macOS. Even if you have enough, running a cleanup is a nice way to start a clutter-free life in Catalina. From redundant apps to caches and leftovers, you can remove any unnecessary items with CleanMyMac X.

How to install a developer beta of macOS Catalina

Downloading and installing macOS Catalina developer beta is an easy deal if you have a Developer account. Here’s how it works:

1. Go to developer.apple.com and click Account in the top menu bar.
2. Sign in with your account credentials.
3. Select Downloads > Install Profile.
4. Find and launch the installer in your Downloads folder.
5. Open the PKG file and agree to the installation.
6. If required, verify the account by entering your system password or with Touch ID.
7. Find the update in System Preferences.
8. Click Upgrade Now to install the beta.

Test macOS 10.15 on a partition

If you’re not ready to give up Mojave just yet, you can install Catalina on a partition. Basically, it allows to split your disk into two parts, so that your computer can run two operating systems at the same time.

To install Catalina on a partition, go to Applications > Utilities > Disk Utility. Your disk will be the first on the list under “Internal.” Select the disc and navigate to Partition tab. Click the plus button to split your disk, name your partition, and customize the size if needed. Click Apply and you’re ready to drive. Or, rather, double drive.

Clean install macOS Catalina on Mac

If you’re determined to give your Mac a new life, run a clean install of Catalina. In contrast to a regular install which puts macOS on top of your startup disk content, a clean installation cleans everything up. Risky as it sounds, a clean install enables a healthier life for your macOS. Just make sure you don’t lose anything in the shuffle:

1. Create a safe bootable backup of your disk with Get Backup Pro.
2. Connect a clean and reformatted external hard drive or a USB stick.
3. On the disk, create a bootable installer.
4. Erase your startup disk with Disk Utility and boot from the new one.
5. When installing macOS Catalina, choose your new disk as the install location.

If you decide to go with a regular install, note that all the clutter from your disk will be transferred to the new operating system. So we recommend to make use of CleanMyMac X smart scanning before you upgrade.

Download and install Catalina Public Beta

A developer beta opens up an early access to all the features. The problem is it’s not free. To get your hands on Catalina with a developer account, you have to pay a yearly fee of $99. Therefore, you might want to wait for Apple to make it public.

Arriving in July, a public beta of Catalina is available at beta.apple.com/sp/betaprogram/. Once there, it takes a couple of steps to upgrade:

1. Log in with your Apple ID.
2. Navigate to Enroll your Mac section and click on “Download the macOS Public Beta Access Utility.”
3. Once downloaded, run the installer.
4. Open System Preferences. You’ll find the public beta update under Software Update (macOS Catalina beta).
5. Click Upgrade now to download the installer. Go through the installation if you want to put beta on your current Mac, or quit to create a bootable USB install drive first.

The pitfalls of Catalina beta

To put it shortly, it’s buggy. Just like any other macOS beta, Catalina can slow down your Mac, freeze, or hinder the work of some apps. It’s ok.

There are a couple of things you can fix, though:

• If you have issues with Sidecar: Ensure your iPad runs on the new iPadOS beta. The feature won’t work on iPadOS 12.
• If an app doesn’t open: Hope you remember, 32-bit apps are dead in Catalina. So if some of your software doesn’t work on the new macOS because of 32-bit architecture, look for alternatives.
• If iCloud doesn’t work properly: Try to close and reopen a document, or download files manually if iCloud Drive fails to load them.

Once you notice imperfections, help to fix them. Beta users can report bugs through Apple’s in-built Feedback Assistant app.

Hopefully, Catalina is worth an upgrade for you. If not, you can downgrade anytime to continue your journey with Mojave. If an operating system doesn’t solve some of your tasks, let Setapp cover the needs. It’s a curated collection of Mac apps that helps you with screenshots, PDF editing, file management, and tons of other jobs—150 at the very least.

macOS Catalina 10.15 is the latest operating system that runs on Apple Mac laptops and desktops. However, it is still in beta test and only available for part of Mac computers with high profile or enrolled in Apple Beta Program. Is there any way to upgrade the macOS to Catalina manually or install Catalina on Mac from scratch? The answer is Yes. But you have to download macOS Cataina DMG or the installer app.

If you are looking for the easiest way to download macOS Catalina DMG on a Macand but don't know how? Well, there are three ways by which you can instantly get the latest macOS installer without a hassle.

Part 1. Get MacOS Catalina DMG Via Direct Download Link

Many people prefer the direct download link of macOS Catalina as it is more flexible. You can unpack the DMG file and make a bootable Catalina installer USB, which can be used to install macOS on other computers. However, it is not easy to find the direct download link because Apple wants you to upgrade from Mac App Store. Fortunately, there are a few good websites that host the direct download link of macOS Catalina DMG. After that, you can burn the macOS dmg to USB to make it bootable for installation.

Tips: After downloading macOS Catalina .dmg file, it is time to make a macOS bootable USB from it. For this purpose, you can give a try on UUByte DMG Editor, one of the most popular software to create a Catalina USB installer on both Windows PC and Mac.

Part 2. Download macOS Catalina From Mac App Store

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.

Mac Os 10.15 Download Link

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.

Step 2: After downloading and attempting to install, an error notification will be prompted. It is due to the unavailability of developer verification credential for macOS. Now, go to System Preferences -> Security & Privacy. Then find the button saying 'Open Anyway' to let the app run.

Step 3: Open macOS Catalina Patcher app and from the main menu, navigate to Options to uncheck the box saying 'Auto-apply Post Install Patches'. As you are done with the previous step and move to the screen as in the link below, hit Download a Copy.

Step 4: The following screen will notify the file size of macOS Catalina you are to download. The resolution is around 7GB and after the download, it will automatically get stored in the Downloads folder. Then hit Continue to initiate the process of download.

Step 5: The download time of the file will depend upon the internet connection and its speed. So, you might have to wait for some while for the process to complete. Eventually, the entire macOS Catalina setup file will be available on your device.

Closing Words

Well, that is all for the day. Hopefully, the above methods were helpful in guiding you on how to download macOS Catalina for both supported and unsupported Macs. When the download is finished, the next step is to burn the DMG file to USB. Then boot macOS from USB and starts the installation wizard.
