Power cable confusion - what's the second cable for?

Apologies in advance for the bonehead question.
I just received my black MacBook, and it works just fine. I'm charging it in a wall plug right now. It's the other cable that has me confused.
The cable is twice as thick as the other one, about 60 inches long, and terminates in (1) the standard three-prong plug and (2) two holes on the other side. The "two-holes" don't fit anything on my iMac or Macbook, and although it appears they're for AC power, there's no adapter included.
What's the point of this cable? What does the three-pronged plug fit into, and how?
Thank, and try not to laugh too hard.

You slide the two prong adapter off the wall wart. The plug that fits into the wall slides off the brick. This is where the extension fits. It replaces this two plug connector and gives you a nice long grounded cable.

    Most computers do not supply enough power to their USB ports to charge an iPad.  Use the charger that came with it.

  • What is the BEST cable connection from Canopus ADVC 300 to Black Magic Intensity Pro HDMI PCI Express Capture Card?

    I must connect an ADVC 300 to a Black Magic Intensity Pro HDMI PCI Express Capture Card.   For best quality, which cable should I use?
    On the ADVC 300 there are outputs of firewire, S-VHS and RCA.
    On BMPro it's a little confusing. On the breakout cable there are connectors that say:
    -5 B-Y OUT
    -4 Y OUT
    -3-R-Y OUT
    -7-R-Y IN
    -8-Y IN
    -9 B-Y IN
    -15 AUDIO IN RIGHT
    -10 AES/EBU OUT
    -12 AUDIO LEFT OUT
    -14 AUDIO LEFT OUT
    -13 AUDIO RIGHT OUT
    With the BMPro, there is also a separate, shorter cable.  On one end it looks like S-VHS and on the other there are two connectors, one black and one blue.
    On the actual BMPro Express card strip instead of using the breakout cable, there is HDMI IN (and HDMI OUT). 
    How should I connect this?  Is there an adapter cable of FIREWIRE TO HDMI? 
    Any help is much appreciated. 

    Well, when I researched how best to digitize VHS (into Final Cut Pro 7), I learned two of the best devices to use are BMPro and Canopus ADVC 300.  I’m using the ADVC 300 for the built-in time base corrector.  I definitely want to use that to stabilize the video.  I also read how well BMPro improves image quality.  So, I thought to use the two together must produce outstanding quality (well, as good as VHS can be). 
    Perhaps I got confused into thinking I can use both.  But the BMPro appears to have an S-VHS adapter. 
    I guess I’m wondering what is better quality: 
    Run the firewire from the Canopus ADVC 300 converter directly into the firewire port on the Mac Pro
    Or, run an S-VHS cable from the Canopus ADVC 300 into the BMPro Capture card
    (I should mention that I have purchased all these items and already have the BMPro Card installed so at this point it’s not a cost issue, but rather an issue of simply which works best?)

  • What's the proper protocol for a reset on my ipod touch 4g?  iOS 6 has totally jacked it up and it will no longer do anything but crash, and won't sync with itunes wirelessly or by cable.

    What's the proper protocol for a reset on my ipod touch 4g?  iOS 6 has totally jacked it up and it will no longer do anything but crash, and won't sync with itunes wirelessly or by cable.
    It's a 64G ipod touch and was fine till Apple told me to upgrade to ios 6.  Now most of my apps crash, my music won't play and I just get a white screen when I hit Music.
    When I try to sync to itunes it acts like it's going to sync and appears to recognize the ipod, but it's grayed out and has an update circle by it that spins for a while until itunes eventually freezes alltogether.  Is there a  way to go back to ios 5 after a erase and reset?

  • What is the correct cable to go from from macbook to my TV - toshiba 24V4210U

    As above, what is the correct cable, and port, to use for watching videos and photos from my macbook on my TV -

    I live overseas where macs and their accessories are not available so I need to purchase this while on a visit to the USA. Thanks!

    Depends on what input plug you'll be using on your TV. VGA, DVI or HDMI. You'll need a Mini DisplayPort adapter and a cable from that to your TV. Here's the various types of Mini DisplayPort adapters on Amazon.com http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=min i-dvi&x=9&y=13#/ref=nb_sb_ss_sc_2_16?url=search-alias%3Daps&field-keywords=mini+ displayport&sprefix=mini+displayport&rh=i%3Aaps%2Ck%3Amini+displayport

  • My sons iPod touch stopped working, it won't charge in a docking station and the computer/itunes won't recognize it when connected.  We have tried holding the power and home button at the same time for several seconds, and the screen still stays black

    Hello skdog I possibly think your ipod touch is black because it has not charged. If your dock is broken it might just mean the dock will be broken and so might be the USB port. You should see an Apple shop nearby and hand it over and see what they can do. I hope this information works!

  • What is an ethernet cable?, what is an ethernet cable?

    what is an ethernet cable?, what is an ethernet cable?

    It can be purchased under the name of Ethernet cable, Cat-5 cable, Cat-5e cable, and Cat-6 cable.
    Most ethernet cables now sold are Patch-type (also called Straight-through), though older Macs (pre-2000 and some 2000 models) needed to use a Crossover-type cable.
    They can be purchased in a wide variety of lengths and colors.

    Yesterday's app here in the UK still appears to be free (at the moment) to download (I don't know what the app's normal price is) : Score! Classic Goals. If it's not free in your country's store then if you want you will need to buy it.

  • What is the second, third, etc. next-hop address in the route-map set command for?

    What is the second, third, etc. next-hop address in the route-map set command for?
    route-map TEST_PBR permit 10 match

    router(config-route-map)#set ip next-hop 1.1.1.1 ?
    A.B.C.D IP address of next hop

    Hi,
    You may get your answer in below link
    http://www.groupstudy.com/archives/ccielab/200812/msg00999.html
    First next-hop will be used unless until that is not unreachable. If first is unreachable, then next one will be used. Since these next-hops are directly connected, router can easily come to know whether they are active or not. In case you want to set some loopback ip as next-hop then you need to use keyword recursive "set ip next-hop recursive"

    To add to what others have said, the three prong plug allows the charger to be grounded, the two prong plug that can plug into the three prong cord assembly does not. There are situations (such as this) in which Apple advises grounding the power adapter to solve problems.

    Please don't shout.
    Has the unit EVER been jailbroke?  Has it EVER been dropped?  Did it EVER get excessively wet?  Did you EVER load a pirated developer's version of the IOS?
    If "No" to all the above, first try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  It could take well over an hour!  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow the on-screen directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
    If you're unable to do the Restore and you have IOS-6 or lower, go into Recovery Mode per the instructions here.  Also, if you have IOS-7, read this.
