I've been attempting to download Catalina. The download will take about 20 minutes and then grey out after saying calculating for a moment. My macbook is like 2014 so it should work according to my research.
I have 23.44 GB free on my hard drive and I'm currently running 10.12.
MacBook Air 13″, macOS 10.12
Hello vkhan02,
Thanks for that info and for choosing the Apple Support Communities. If I understand correctly, you are unable to install macOS Catalina on your Mac, as the install button goes grey unexpectedly. First, try running First Aid on your hard drive with the built in Disk Utility tool, as this can correct simple issues like you're experiencing. Then delete the current installer and download the installer and try the process again.

Next, use safe mode to start up your Mac as it does the following things:
Log in to your user account and test the issue while in safe mode and then restart normally and test the issue again.
