How To: Enable TRIM with Non-Apple SSD

The guide breaks the process down into three steps, all performed via copying and pasting the code snippets through the terminal window. To launch a terminal window, open the Utilities folder inside the Applications folder and select terminal.

The first step makes a backup of the original IOAHCIBlockStorage file called IOAHCIBlockStorage.original. You will be prompted to enter in your system password when using the "sudo" command, since you are modifying system files. Copy and paste the code into the terminal window, a successful or uneventful response is a new blank terminal line.

sudo cp /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage.original

Stuff I learned about Puppet

Chef vs Puppet

• My blink is that in 2012 Puppet is safer and more productive.
• Puppet is declarative, Chef procedural.
• Puppet brings system into compliance (state), Chef "does" things (recipes).
• Puppet has strong security practices; Chef has a toleration for loose security in Chef itself.
• Puppet makes it very hard to get "outside the lines" or violate its strong opinions; in Chef this is routine.
