First, clear out the junk
When you do a regular upgrade, the installer replaces some files on your Mac with others, but leaves most untouched. That means that all the system junk your Mac has accumulated over the years stays there. And as you upgrade year after year, you accumulate more and more. As you can imagine, upgrading your operating system on a junk-filled Mac is rather like putting one layer of wallpaper on top of another — eventually you have to scrape it off and start again.
Likewise, it’s always a good idea to clear out the clutter before you upgrade. My recommendation, after years of experience upgrading Macs, is that you use CleanMyMac X. It’s very quick and easy to use and will get rid of clutter, making your Mac run more smoothly and freeing up tens of gigabytes of disk space. You can either let it decide what to remove or go through its scan results yourself and decide what to trash and what to keep.
Then, backup your Mac
As you will see below, there are a couple of different ways you can upgrade to Catalina, but before you decide, and certainly before you upgrade, you should make a full backup of your current Mac setup. Upgrading one OS on top of another carries very few risks, but they are not non-existent so be safe now rather than sorry later. If you use Time Machine you can make a backup with that. But the best idea is to make a complete bootable clone of your current startup disk on an external drive.
To clean install or not to clean install
Remember I said you had a couple of options for upgrading? Here they are:
Regular install
Clean install
A regular install places Catalina files on your startup disk over the top of whatever OS you’re currently running. It doesn’t overwrite anything else. So all your applications, documents, settings, photos, movies, and music stay where they are. Unfortunately, all the junk files your Mac has accumulated also remain there. This option is quicker in the short-term, but your Mac won’t run as smoothly in the long-term. If you choose this option, I’d definitely recommend you use CleanMyMac X to clear out the clutter, before you upgrade.
A clean install erases your startup disk completely and then installs macOS Catalina on a completely clean disk. It takes longer, but in the long run your Mac will run more quickly and more smoothly. You will have to clone your startup disk before you start, and then spend time reinstalling applications and setting them up afterwards, however.

My apps are slow or stopped working on macOS Catalina
Okay, you’ve successfully installed macOS 10.15 Catalina. But some of your apps are no longer available. That’s a heavy blow from macOS Catalina as it no longer supports 32-bit apps. According to Apple, 64-bit apps are more memory-efficient than 32-bit ones. But for most of us it means we will lose many favorite games and applications, including Photoshop CS. To minimize the damage, you should first check how many 32-bit apps you have. It's possible to do with the same Mac maintenance app we've mentioned above.
Run CleanMyMac X — you can download a free edition here.
Click the Uninstaller tab.
Now, by clicking on the 32-bit tab, you will see the list of 32-bit apps on your Mac.
Next up, click the Updater tab. Here you can update your 32-apps (and all the rest of apps) to newer versions. Many developers have already optimized their software for 64-bit architecture. With this method you’ll update all your software in one-go to make it Catalina-friendly. As you can see, I can update 17 apps with just one button.

Create patched macOS Catalina USB installer
After checking if your Mac is supported, follow these steps:
1. Download the latest version of macOS Catalina Patcher from here (http://dosdude1.com/catalina/). Because developers continue to update applications with the latest patches and hotfixes, always download the latest version.
2. Run the application and click Continue.
3. On the next screen, click Download a Copy. We will use this option because we will create a bootable USB drive installer.
4. The installer is about 8GB in size, so it may take some time to complete the download.
5. When finished, you will be given the choice of installation method. Here, insert the plug-in into the USB flash drive and click 'Create a bootable installer'.
6. After creating the drive, plug it into an unsupported Mac and install macOS Catalina in it. Turn on your Mac and hold down the Option key. You will see the startup manager. Use the arrow keys to select the bootable USB drive and click Return.
7. When you boot into the macOS recovery environment, make sure to use Disk Utility to format the internal drive (the drive used to install macOS Catalina) to APFS. This step is required if you want to update from a very old macOS version that does not support APFS.
8. The next step will use the 'Reinstall macOS' option to begin the installation process. Let the installation process complete. During this process, you may see some command line messages. These are perfectly normal and are part of the installation process created by the developer to ensure compatibility.
9. After the installation is complete, shut down your Mac and then restart it using the USB drive again. The reason for this is that you can apply an installed patch to ensure that Catalina works properly on your system.
10. After returning to the macOS recovery environment, click on the option that says 'macOS Post Install.' By default, the installer will select all the correct patches required by your Mac. Click Apply Patch and complete the process.
11. After applying the patch, select the option that says 'Force Cache Rebuild' and click 'Restart'.
