how to download catalina on an unsupported macbook for my older macbook
Hello, I'm trying to download Catalina and it won't let me because it says unsupported device because this is a newer MacBook but I wanna make a bootable installer on my USB flash drive so I can reformat my older MacBook because no options to format or letting me do it how do I bypass the not supported MacBook so I can download Catalina from the Apple Store please or where else can I download Catalina to make a bootable installer?
MacBook Air 13″, macOS 15.0
