I'm still on Mojave on the machine I'm typing on.
Since Catalina drops 32Bit support, it will be a while before I move.
I'm not interested in buying/updating software when Apple decides too change the OS.
I never take an OS update when released, because I can't afford to have my machines go down.
I need to wait for some of my software vendors to verify compatibility.
Not so much on my laptop, but my MacPro runs ProTools and all I need is to have my system DOA after a software upgrade.
I usually lg a year behind so they can work out all their bugs. I'm on Mojave 10.14.5
