Mac Pro introduced in early 2008 or later Xserve models introduced in early 2009. To find your Mac model, memory, storage space, and macOS version, choose About This Mac from the Apple ( ) menu. If your Mac isn't compatible with OS X El Capitan, the installer will let you know.
I would like to instal with use of Homebrew. I'm performing the following command: brew install putty which gives the seemingly correct output: Downloading Already downloaded: /Users/thisuser/Library/Caches/Homebrew/putty-0.67.elcapitan.bottle.tar.gz Pouring putty-0.67.elcapitan.bottle.tar.gz ? /usr/local/Cellar/putty/0.67: 11 files, 1.5M However, the putty command is not recognised: thisuser-541/41:$ putty -bash: putty: command not found. Update: Current stable version (.67) of putty can't be build with gtk+2 support on OS X using homebrew. This is a know issue. It seems you can install from HEAD version ( brew install -HEAD -with-gtk+3 putty) and for me that is also broken. Brew install putty by default installs from a pre-built bottle.
The pre-built bottle for putty doesn't include putty, puttytel or pterm. If you want putty then can try installing from source. First remove the installed putty formula by running brew remove putty. After that install putty from source by running brew install -build-from-source -with-gtk+3 putty. NOTE: As of this writing building putty from source is broken with homebrew.
