I'm new to Mac Mojave but not to macs or software. The Pkg file from MacTex does not respond to double-clicking or to pressing click, then pressing the "install" button. Can anyone suggest how to get this to run? My computer is a macbook pro 2018 and I'm downloading with Safari. Thank you kindly for any help. I did look at your "similar questions" but they don't seem to be the same. Thanks again.
