<div>Greetings,</div>
<div> </div>
<div>I have a couple of MACBook Pros and a MAC Mini that suddenly freeze with the following message:</div>
<div>“You need to restart your computer hold down the Power button until it turns off then press the Power button again.” </div>
<div> </div>
<div>If I power off and on the MACBook Pros, they works fine, and the Mac Mini works fine when I connected to another LCD.</div>
<div> </div>
<div>Any suggestion or tips to solve this problem will greatly appreciate.</div>
<div> </div>
<div>Thanks,</div>
