If your system is running on macOS High Sierra, Sierra, or El Capitan, then you can just go to the App Store and look for Catalina. Read the features and just install macOS Catalina from here. Alternatively, you can also go to the official website of Apple and click on the 'Upgrade Now' button to start the process. Thanks for watching! New here?YouTube: https://www.t.me/iMATiOSPatreo.
Most coverage of macOS Catalina focuses on the improvements since Mojave, its immediate predecessor. But what if you’re still running macOS High Sierra? Well, the news then it is even better. You get all the improvements that Mojave users get, plus all the benefits of upgrading from High Sierra to Mojave. Let’s compare macOS Catalina with macOS High Sierra.
Clean your Mac before you upgrade
Before we get started, if you’re planning to upgrade to macOS Catalina from High Sierra, you likely have lots of files on your Mac that you don’t need. We call them system junk. They consist of cache files, temporary files that were never deleted, and all sorts of other data macOS stores on your Mac and you’ll never need again. Installing a new OS over that lot is not a good idea; it’s like layering paint over paint – at some point, you have to sand it down and start again. That time is now before you upgrade. My favorite way to get rid of junk files is to use CleanMyMac X. It’s really easy to use, quick and can free up tens of gigabytes of space.
Once you’ve got rid of the junk, backup your Mac either with Time Machine or a tool that can make a bootable clone. It’s very rare that anything goes wrong when you upgrade, but it’s much better to be safe than sorry.
The evolution of the interface
macOS Mojave saw one of the biggest changes to the macOS interface in several years, so if you’re still using High Sierra, upgrading to Catalina will allow you to use features like Dark Mode, which changes the look of your Mac and all applications that support it so that they display light text on a dark background.
Mojave also introduced Desktop Stacks, so if you’re still running High Sierra, you’ll be able to use those for the first time in Catalina too. Stacks allow you to automatically store files of the same type, like photos, PDFs, and screenshots, in a stack on the Desktop. Talking of screenshots, Mojave changed the way screenshots work. Now, instead of just saving your screenshot, it hovers as a thumbnail for a few seconds, so you can click on it to preview and make some basic adjustments before saving or deleting it, just like on your iPhone. Then there are the new features in the Finder, like the Gallery view and the new Quick Look tools that allow you to make changes to image files when you preview them in the Finder.
Compared to the leap from High Sierra to Mojave, Catalina didn’t add too much to the visual interface but made huge improvements to the way you use your Mac with your Voice. You can now control your Mac completely using just your voice, including launching apps, selecting commands, dragging and dropping, and, of course, dictating.
Applications
macOS Mojave and Catalina have brought iOS and macOS closer. First, there was the addition of Voice memos, Stocks, and Home apps to the Mac. Then, Apple got rid of iTunes and replaced it with TV, Music, and Podcasts to mirror the equivalent apps in iOS. The Mac App Store has also been overhauled since High Sierra, making it easier to find the best apps and allowing developers to offer trial versions.
There’s a new FindMy app that replaces Find My iPhone, Find My Mac, and Find My Friends, and it can find your Mac even if it’s sleeping or offline. And you’ll notice improvements in lots of Apple’s built-in apps like Reminders, Notes, Safari, and Photos which are rebuilt in Catalina. You can now mute entire threads in Mail, just as you can in Messages, and make group calls with FaceTime.
All devices are welcome
In Mojave, Apple added the ability to use your iPhone’s camera to scan documents directly on your Mac. And it continued that theme in macOS Catalina by allowing you to use an iPad as a second display for your Mac and as a graphics tablet. A feature called Continuity Markup also allows you to markup PDFs on an iPad and have the changes show up on your Mac. Finally, Mojave added a feature that allowed you to unlock your Mac with an Apple Watch. Catalina has taken that further by allowing you to authenticate certain actions on your Mac by clicking the button on an Apple Watch. Apple’s iOS devices now work much more closely with the Mac than they did in High Sierra.
iCloud
Apple has added a lot to iCloud since High Sierra, turning it into a serious alternative to Dropbox or Google Drive. For example, you can now sync your Desktop and Documents folders in iCloud, meaning they will be the same no matter which Mac you log into your iCloud account. And you can now share entire folders with other people, rather than just individual files.
More gatekeepers and security checks
There have been some big improvements in this area since High Sierra. In macOS Mojave, Safari made it much more difficult for websites to follow you around the web by preventing so-called ‘fingerprinting.’ In macOS Catalina, apps will have to ask permission to access your Desktop or Documents folders, as well as iCloud Drive and external disks. And they’ll also have to get your permission before capturing keyboard strokes or taking a photo or video of your screen. And macOS Catalina introduces Activation Lock, which means only you can erase or re-activate your Mac.
What if I don’t feel like upgrading?
Many people live happily using older operating systems because old is gold, right? But if your Mac is underperforming and you think that the mere switch to macOS Catalina will solve everything, you’d likely be disappointed. But the more realistic way to improve the performance of your macOS is freeing up its memory and removing old apps. Really. We’ve seen many good-maintained Macs running the ancient El Capitan that actually performed better than the latest machines.
Install Macos High Sierra From Catalina
So, here’s the cheat sheet to improve the performance of your Mac:
- Free up space on the startup drive
- Switch to some lightweight browser, other than Chrome, for example, Brave
- Minimize Login Items via Preferences
- Use third-party macOS speed up tools
For example, there’s a special instrument that comes with CleanMyMac X that identifies heavy memory consumers on your Mac. The tool is called Heavy Consumers, and you can use it to make your Mac more responsive. However, many Apple forums recommend it for slow-performing Macs.
Download the free version of the app and check if it helps your Mac.
When you compare macOS Catalina with macOS High Sierra, the differences are huge, so it's well worth it if you haven’t upgraded already. However, you should definitely take steps to clear the junk from your Mac before installing the newer macOS. CleanMyMac X can do that for you quickly and easily. Let it decide what to remove, take control of, and make the decisions yourself; you can use it however you choose.
MacOS Catalina, macOS Mojave, and macOS High Sierra download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra.

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.
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.
Can I Install Catalina From High Sierra
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.
It does not matter whether you use macOS or Windows 10. It’s just a matter of time until your device will refuse to start, which could happen for many reasons, including (and not limited to) file corruption, hardware failure, and buggy update. If the unexpected happens with an Apple computer, you can use a macOS bootable USB with the installation media to repair it.
This is one of the main reasons you should consider making a macOS bootable USB when your device is working properly. However, if none of your devices (MacBook, MacBook Air, MacBook Pro, iMac, Mac Pro, or Mac Mini) aren’t working when you need them the most, then you can use a PC to rescue your Apple device. You can use a Windows 10, Windows 8.1, or Windows 7 device to quickly create a USB bootable installation media to reinstall macOS Catalina or Big Sur on your Mac.
In this guide, you’ll learn the steps to create a macOS Catalina bootable USB installation on Windows 10, which you can use to reinstall or upgrade the Apple OS.
Requirements
Before proceeding, you’ll need the following:
- Broken Mac computer running macOS (version 10.12, 11, or later).
- A trial copy of the TransMac software.
- One high-quality USB flash drive with 16GB of storage.
- Copy of macOS (DMG file).
Create macOS bootable USB installation media
To create a bootable USB drive with macOS, use these steps:
Download and install TransMac on the Windows 10 device.
Quick note: This is a paid software, but it gives you a 15-day trial, which is more than enough time. (If this works for you and you want to support the developer, you can purchase the full version.)Connect the USB flash drive. (If you have any data on the flash drive, remember to make a backup, as everything on it will be erased.)
Right-click the TransMac app and select the Run as administrator option.
Click the Run button. (If you’re using the trial version, wait 15 seconds.)
Right-click the USB flash drive, select the Format Disk for Mac option from the left navigation pane.
Quick note: You want to do this before creating the bootable media because there is a good chance that the drive was formatted using a Windows device. If this is the case, the chances are that it’s using an MBR partition, and the USB drive needs a GPT partition to work on a Mac.Click the Yes button to format the drive on the warning message.
Confirm a name for the drive. For example, “macOS bootable USB.”
Click the OK button.
Click the Yes button.
Click the OK button.
Right-click the USB flash drive and select the Restore with Disk Image option from the left navigation pane.
Click the Yes button to confirm the erase of the USB flash drive data.
Click the browse button on the right.
Select the .dmg file with the macOS installation files.
Click the Open button.
Click the OK button.
Click the Yes button.
Once you complete the steps, you can now insert the USB flash drive on your Mac computer to install, reinstall, or upgrade the operating system to the latest macOS version, which can be Sierra, Catalina, Big Sur, or higher.
Create a GPT partition on USB flash drive
If the USB flash drive is not working with TransMac, it could still be a partition problem. In this case, you may need to redo the entire process again. However, this time you should use the following steps to use the Diskpart command-line utility on Windows 10 to create the appropriate GPT partition, and then follow the above instructions.
