Let's make sure you did each command. 

First, is your default shell already the bash shell? Execute the command `echo $SHELL` and it should return /bin/bash if it is. You can then forget about the first command (bash).

Next run `umask 002` which just makes sure everything has the right permissions.

Very important: not run `cd /Volumes/TEXCOL2016/texlive` so the directory becomes the place where install-tl resides. (The error message seems to indicate that the command wasn't found.)

Finally run the last command which does the actual install. It needs to be all on a single line.` (Don't copy it from this email since it's very long and you may have hard wrap on.)

For letter paper default:

`sudo ./install-tl --no-warn-checksums --profile /Volumes/TEXCOL2016/mactex/MacTeX-Install/TLprofiles/texlive.profile`

For a4 paper default:

`sudo ./install-tl --no-warn-checksums --profile /Volumes/TEXCOL2016/mactex/MacTeX-Install/TLprofiles/texlivea4.profile`

Good Luck,
