Downloading YouTube videos for offline viewing (on you iPod or in iTunes) is a lot easier than you may initially think. Of course, there are utilities like TubeSock that will copy videos from YouTube for you. This will however set you back $15. Why pay $15 when there’s a free and easy way to download videos from YouTube?
Following recent contact between a major member of the media and Apple, it was revealed that Apple has today made a fix available for random shutdowns that will eliminate the need for customers to send their systems in for warranty service!
The fix takes the form of a SMC (System Management Controller) firmware update.
Jason Siebert, aka Sieb (thatsiebguy), who took the photo of the melted insulation featured on our demystified post points out that the shut downs may be caused NOT by an electrical short circuit problem but rather by the high levels of heat that the sensor cables are exposed to. Heat increases the resistance of the electric sensor cable and this results in a decrease in the current through the cable which in turns lead to altering the signal sent by the heat sensor (thermistor). If this signal indicates a high enough temperature, it is possible that the MacBook just shuts itself down to prevent any damage to the processor.
Thanks to some pictures of the MacBook heatsink on Flickr, the cause of random shutdowns in the 13″ MacBooks is now clearer! As previously thought, it is indeed an insulation issue. Here’s a close up of a melted heat sensor cable:
The area where the cable insulation melts actually houses a pair of cables and it is suspected that this is where the short circuit triggering a shut down occurs (when those two cables make electrical contact).
Creating a folder named Demo Mode on your 5G iPod and renaming a video of your choice Demo in iTunes will activate that video as a screen saver on your iPod when it’s charging!
