Now if you already have a .ppk file from your PC that you want to convert to use on your Mac you need to visit the Putty Website www.chiark.greenend.org.uk/~sgtatham/putty/download.html and download puttygen.exe (on your PC) now open it, and using the File menu, load your .ppk that you already use, and type in your pass phrase.
Now go to the Conversions menu and export the key as an OpenSSH key – hey presto – you now have a key file that will work on your Mac! Such a simple solution, yet that took me so long to figure out …
Anyway, now you just need to copy your new .ssh keyfile over to your home (~) directory on your Mac and set the permissions to 700 (chmod 700 yourkey.ssh).
Once you’ve done all that you can use the ssh command.
ssh username@123.123.123.123 –i yourkey.ssh
and you should be able to SSH onto your box as you would from your PC
