I am using 2015 MB Air too. Just do clean install to El Capitan after updating to Catalina. Suddenly the it can't boot and stuck with Apple logo for a night. Reinstall from Mac's recovery not working. Spent 2 days to fix it and finally do the clean install using El Capitan. Now, I don't bother to upgrade anymore. Answer: A: Well it is up to you if you want to upgrade or not. Upgrading from El Capitan to Catalina is a big jump and includes. The reformatting from the old HFS+ file system to the new APFS file system. Some have reported the installation stalling when upgrading from the older OS's. The first release of the new OS — Mac OS X Server 1.0 — used a modified version of the Mac OS GUI, but all client versions starting with Mac OS X Developer Preview 3 used a new theme known as Aqua. Aqua was a substantial departure from the Mac OS 9 interface, which had evolved with little change from that of the original Macintosh operating.
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.
Chances are, your Mac can run macOS Catalina.

Make sure you’re ready to upgrade.
Before you upgrade, we recommend that you back up your Mac. Then, if your Mac is running OS X Mavericks 10.9 or later, you can upgrade directly to macOS Catalina.

Learn how to upgrade to macOS Big Sur, the latest version of macOS.
Check compatibility
The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.
If a macOS can't be used on your Mac, the App Store or installer will let you know. For example, it might say that it's not compatible with this device or is too old to be opened on this version of macOS. To confirm compatibility before downloading, check the minimum hardware requirements:
- macOS Catalina 10.15 hardware requirements
- macOS Mojave 10.14 hardware requirements
- macOS High Sierra 10.13 hardware requirements
- macOS Sierra 10.12 hardware requirements
- OS X El Capitan 10.11 hardware requirements
