How to Convert PPK PuTTY File to PEM on OS X 10.11 or Later

If you don’t have PuTTY installed these days, use Homebrew to do it painlessly. Don’t have Homebrew?

Open Terminal and paste:

ruby -e "$(curl -fsSL

Then type the command:

brew install putty

Then PuTTY should just work fine without any hassle. The command for converting a PuTTY Private Key would be:

puttygen privatekey.ppk -O private-openssh -o privatekey.pem

CD or DVD Stuck in Mac – How to Fix

I was going through some old CDs and they were pretty scratched. Some of them could not be read so my computer was a little slow on making a decision and spitting the discs back out. At one point, a certain CD didn’t come out at all (and was not showing up anywhere). In fact, I completely forgot it was in there. By that time, I had to resort to opening Terminal and typing in:

drutil tray eject

Then your disc will be out in a jiffy.

PuTTY for OS X? No thanks.

Many folks coming from the Windows world often ask where they can find the PuTTY client for OS X. While I do not wish to undermine the quality of the client (as it is, quite likely, the best for Windows), there is no such need for it on OS X. Why? This is simple – because all of the functionality that PuTTY offers, such as SSH, Telnet and Serial abilities come bundled with your OS X install. Since OS X is based on UNIX, it comes with a massive array of utilities that can be found across most different UNIX based OS’s and SSH and Telnet is no exception.
