Hi everyone!

Today I was prompted to install the AutoCAD 2021.2 update on my Mac but I am wondering if it is mandatory to install the update?  Is it ok if I just ignore it?  Last time after I installed an update at home, my AutoCAD stopped working for a few months! Luckily we were back in the office to work around that time but now I am working from home again, and I cannot afford to lose AutoCAD.  My macOS is version 10.13.6 and I am not sure if the AutoCAD 2021.2 update works with this version of macOS. 

Anyone has any thought please?

Many many thanks.
