I haven't followed this entire thread, but I'm running macOS 10.15.2 Catalina on a 2014 MacBookPro, and I haven't had problems downloading the latest version of R.  Roughly a month ago, I clicked "R-3.6.2.pkg" on "https://cloud.r-project.org/bin/macosx/".  It downloaded to my "Downloads" directory.  Then I double-clicked on it, and it opened.  I can't remember, but I may have had to click and drag the icon to the "Applications" folder.  And I may have had to enter my password to assure macOS that it was OK to run that application.  I may have had problems with this a few years ago, but I haven't had a problem recently.  However, I may misunderstand your question.

Why not use the official installer and adjust the installation path?

Also allows multiple versions being installed, all from the CLI (but I
guess guess it's a normal desktop machine and you can just use the gui
installer).

256GB is a normal size for a disk, don't see the problem. 90% of all macs
probably don't have more.

Homebrew R differs slightly from the official R installer and might cause
problems in some cases.

Thank you so much for you assistance.

My problem is not solved, because I must install R, etc. on a different
Volume like SYS-Volume & I can´t find this option under "homebrew".....

Betreff: Re: [R-SIG-Mac] Using R on MacOS Catalina.....

For me it usually had to resort to the latter when there were connectivity
issues (more common in Namibia than in Potsdam :-)-O).

And maybe once or twice when I wanted to try something special.

It also has a 'cask' option with which it installs apps so I do

brew install r
brew cask install rstudio


All in all rock solid.

Homebrew is Linux-style packaging for OS X. Think of it as an
equivalent to apt-get—either it will retrieve a binary or it will
attempt to build one.
