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. There is currently talk of a future update coming to Windows, but for now, Apple continues to support iTunes for Windows. Using an older macOS or Mac OS X version? For folks with older Macs that don’t support macOS Catalina and for folks not wanting to update, you can still use iTunes to update to the latest version of iOS and iPadOS.

If you're using one of these computers with OS X Mavericks or later, you can install macOS Catalina. Your Mac also needs at least 4GB of memory and 12.5GB of available storage space, or up to 18.5GB of storage space when upgrading from OS X Yosemite or earlier.
