Take stock of your health

Your Mac makes his own for some time and you really imagine her state of health. Before calling the maintenance check on our own state of freshness of our beloved companion. No need to buy any software to check all this, there is one ready in every Mac based Intel, I named: AHT. Hum! Sorry, I meant Apple Hardware Test . In short it is a tool for checking the internal components of your Mac (motherboard, memory, modem, memory VRAM - Video RAM and the AirPort card), except the hard drive and third of the original components.

Launch AHT
To start on AHT, simply restart your Mac while pressing the 'D ' like ... D IAGNOSIS . Attention to the stunned (like me), do that the key 'D' and not Command-D for example.
After a long moment of anguish when the screen goes gray apple without this, a screen appears similar to this:

To a complete test (preferable if you really want to be sure that the components of Mac work perfectly well), check "Perform extended testing " then click the button "Test .
is then gone for a good hour test (1 hour 1 / 4 for my iMac 24 "2.66Ghz - 640 GB / 4 GB).

few more scares, one sometimes gets the impression that the tool plant because it remains frozen for long periods. Do not worry about the time that appears, it does not represent reality, and especially do not refresh in real time.

then begins the test of memory represents the Much of test and then comes control of the motherboard and its components, and again a little fright (really) when the fans start to turn back the cranks, we must say to not accustomed to hear them like that .

Once testing is complete, the record appears for you and I hope it will be as good as mine. You're so knowledgeable about the operational status of your Mac.

As for the proper functioning of your hard drive, I advise you to check its mechanical condition with the software SMART Reporter and its software structure and its permissions with Utility Disk your file Utility in Applications . But I do it again some time in an article on the subject.
