Hi there, long time no see 🙂

I haven’t been wring here for a long time now. Let's change that!

So, today just a reminder. A new security problem has been discovered in Intel’s Thunderbolt USB-C connectors (also older versions). I will not go into details, just wanted to remind you about one security setting on Mac’s that you can use to minimize the risk (not get rid of it).

Sleep cycle of the system. Mac OS has 3 types of sleep cycle:

suspend to RAM only (default on desktops)
suspend to disk only
suspend to disk + RAM (default on laptops)

Now to increase the security of your MacBook, you will need to set the sleep mode to no. 2

To do so, here are some CLI commands to help:

sudo pmset -a hibernatemode 0″ = suspend to RAM only (default on desktops)
sudo pmset -a hibernatemode 25″ = suspend to disk only
sudo pmset -a hibernatemode 3″ = suspend to disk + RAM (default on laptops)

Hope this helps.
