Even though it says it is possible there have been a lot of reports of the install freezing.
Part of the installation is the conversion of the file system from HFS+ to the newer APFS system.
Let them figure out the major issues that can break your device. If you want to play it absolutely safe, wait for a.2 release — as in macOS Catalina 10.15.2. By that time, Apple will have pushed out al least one bug fix update (10.15.1), so it’s likely that the one after that will be a much more stable release. Upgrade to macOS Catalina. When you upgrade to macOS Catalina, you get more of everything you love about Mac. Experience dedicated apps for music, TV, and podcasts. Smart new features in the apps you use every day. And Sidecar, which lets you use iPad as a second Mac display. Best of all, upgrading is free and easy.
MacOS Catalina, the latest version of the world’s most advanced desktop operating system, is now available as a free software update. With macOS Catalina, users are able to enjoy Apple Arcade, a groundbreaking new game subscription service featuring new, exclusive games from some of the world’s most creative developers.
And this is where the install freezes.
Upgrading from Mac OS X Older Versions. Any older versions of Mac OS X 10.7-10.10 have to first upgrade to Mac OS X El Capitan 10.11 version before upgrading to macOS Catalina, which you can download from Apple’s Catalina download page. To do this, follow these steps: Launch the System Preferences menu, and thenselect Software Update. 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. Or, launch the App Store application and find macOS Catalina either from the Featured tab (⌘ + 1).
I would have recommended upgrading to macOS High Sierra as an intermediary step.
High Sierra was the first OS to use the APFS system and would have installed the firmware
necessary for it.
If you want to install macOS High Sierra click on the link below and go to Download OS
and select High Sierra.
