How to create an OS X Yosemite 10.10 USB installer

Last Updated: June 10, 2015

The problem:
Starting from Lion (Mac OS X 10.7), Apple operating systems no longer come with a bundled install DVD, which has been replaced by a hidden recovery partition that can be used for the same purpose. While this has surely meant a remarkable cost slashing for Apple, it has created some inconveniences to users. It's actually pretty easy to reinstall OS X from Recovery Partition but it requires an active Internet connection in order to download the needed files from Apple servers and it's a very slow procedure. This is a consequence of the so-called cloud computing revolution. But, what if we need to reinstall OS X without an active internet connection or we cannot access Wi-Fi from outside the operating system?
Luckily there's an easy fix for this problem: create an emergency boot disk on a bootable USB drive that will work the same way as an install DVD.

How to create a bootable Linux USB drive with Linux Live USB Creator

I'm currently studying Linux this semester and I found myself with the problem as my college uses Windows and the professor gives additional points is used Linux for your exercises.

I happened to have a 1 GB pen drive and I decided to create a bootable live Linux distribution on it.

So, after downloading the iso image of the distribution I wanted, I downloaded Linux Live USB Creator.

This program is very easy to use.

After choosing the destination pen drive, navigate to the ISO image of the Linux distribution.

How to create a portable virtual machine of Windows 7 Professional with VMware Player


  1.  A physical Windows system: you can use a virtual machine only if it's compatible with VMware Player but a physical OS is faster, regardless. For these reasons I've used my laptop, running Windows 8.1.

How to re-create a missing recovery partition in OS X

Last Updated: 4/26/2017

Note: The original version of this post was referred to OS X Yosemite, but the same procedure is generally valid, regardless of the specific OS X/macOS version installed in the system. Some changes were also needed due to the new Disk Utility features introduced by El Capitan.

If you've happened to use a clone created with software like Super Duper!  to restore OS X from a rocky situation, you may find yourself with a system working smoothly but not having a Recovery Partition.

Though you could always restore the clone image in case of problems, this is not an ideal situation.

In fact, a minor problem could be more easily solved by repairing the disk  through Disk Utility/First Aid from OS X Utilities menu, instead of overwriting the whole drive.

Why being paranoid can be a skill

In IT you need to have a disaster recovery plan, which means you need to think of the worst case scenario every time.

That's why paranoia is one of the best skills of an IT security professional.

I've been screwed up so many times in the past that now I follow three simple rules:

In the meantime a new operating system has been released, i.e. OS X 10.10, commonly known as Yosemite.

Though some of the features explained in the previous post have remained unaltered, I think it's best to review the above post regardless.

Mac tricks you don't probably know

  1. Shift the screenshot selection area: OS X allows to take a screenshot of a selected area of the screen with CTRL/SHIFT/4. If you need to select an area located slightly above or below your starting point, press SPACEBAR without releasing your mouse to shift the selection where you need it.
