Notarize the installer per macOS Catalina

[coatless]

From #23, I think we might have to notarize the installer app.

Ran into an issue today (and glad there's a thread thank you!) I tried to install the pacakge on Mac OS Catalina, looks like Apple changed (or disabled) installing Command Line Tools.

If you run into a similar issue as I did, you can access the file from

• https://developer.apple.com/download/more/

Once you download/install Command Line Tools for Xcode 12, you're good to go :)

@mhwangbo11 can you show me a screenshot? I'm not able to verify a change for command line downloads of Xcode CLI.

Let me know if this helps... I just noticed that there's an update coming from Apple on Xcode

@mhwangbo11 what was the installer view like? Or was there a log output?

When I tried to install it via R Studio, one of those installer windows with globe(?)/orbit(?) popped out then the prompt said unable to install. Then when I downloaded this dmg, worked out as soon as I installed it and restarted my Mac.

And this may help as well? since all the slides on the link were almost as same as what I went through. https://www.ics.uci.edu/~pattis/common/handouts/macmingweclipse/allexperimental/macxcodecommandlinetools.html
