I was sitting here monitoring data activity in the Activity Monitor. I had nothing running, not even the wifi from my airport, but I was seeing spikes incoming and outgoing data. The outgoing would be about 1/2 of the incoming data most times, but at times would be closer to 2/3 of the incoming. This is with no applications running. Can someone explain to me why I'm seeing this? Thanks

Not really answering, but....
You NEVER really have nothing running. Perhaps no user-started applications, but Activity Monitor, in CPU mode, will always show stuff using the CPU(s).

Two points. Open networks are always active with constant checks and behind the scenes housekeeping. Second, you need to look at the numbers, not the graph alone. The graph scales so that when there is minimal activity, the spikes still look huge. In fact, spikes generally mean no significant activity. Real network activity would have flatter plateaus. Spiking means light bursts.

My wife received a MacBook Pro from her school yesterday. It worked yesterday but would not turn on today. She did charge the battery last night, the little light on the charging cord turned green
Her IT person discovered that the battery was only charged to 36% this morning so she kept the laptop and hooked it up to charge. Meanwhile there were quite a few other employees who had the same problem.
The eventual solution given was that the MacSafe Power adapter will only work with the three prong extension cord. It will not charge the computer while using the installed two prong plug.
I find this difficult to believe. Why would Apple supply an item that is useless? Since the third prong is a ground why would that affect charging? Also the computer should have powered up with 36% battery power.
I use the three prong extension for my MacBook Pro (purchased by me, not supplied not employer) but I am certain that I originally charged the computer without the extension cord.
Your input will be appreciated.
Thanks,
Bobby

I think that's extraordinarily unlikely. I've never seen a MacBook Pro that wouldn't charge from the 2-pronged plug that flips out of the charger/AC to DC converter. I've used that brick on 110 V ac in the US, with a plug that adapts its prongs to Western European non-grounded 220 V ac configuration, and even with an Apple Extension cord that for some reason has a missing "ground" pin.

Howdy.
Your wife's IT person is 100% wrong.
I have numerous Apple battery devices in my house and they all charge
fine with the supplied Apple made two prong non grounded power adapter
and have been for years.
Something else is going on.
If the MacBook Pro had been stored over summer break, this might be
part of the problem.
It is possible that the report of 36% charged is not accurate.
One thing to also try is to let the battery discharge 100%, not plugged
into electrical power, and then shut down the computer. The plug in
and let it fully charge. This may reset the device that makes the
percent charged figure accurate.
Ask you wife to read the following paper at Apple's Knowledgebase and
then try the things listed in it.

Well, it sounds absurd in many ways, so I am extremely skeptical, but anything is possible. If the orange light goes on, the MagSafe believes you are charging. When green, you are charged to the degree that the particular battery can be charge. BUT the MagSafe chargers determine this using very simple chip "brains" and while simple brains tend to be highly reliable, they are not infallible. Still, this seems like the least likely answer that I can think of.
And yes, the third wire is ground and should not factor if properly wired, but again, because of the aforementioned chips, this could conceivably come into play.
We can help you troubleshoot the battery if you wish, but as I have now encountered two school supplied laptops, I can tell it that my troubleshooting can't help with the school bureaucracy. I can also tell you that school IT departments make some pretty bizarre diagnoses. Which is not to say I don't sympathize deeply with those who do this job.
I would suggest you check the MOST likely cause. On the Apple menu (upper left corner), select About This Mac, and then the More Info button. I the window that appears, on the left under the "Hardware" category, select Power. On the right, scan down to the listing tell us what it says under Charge Information.
And the model of the Macbook which you can see by selecting Hardware.

Just read an article on how "Leap Motion" is going to change everything we do media wise. Looking at a 27" iMac in the present, and I wonder why I would want "Leap Motion" on a computer screen, unless I wanted to do a lot of upper body exercises as I surf or work. I have a trackball and a keyboard. For the most part my arms remain motionless except to type. Why do I want to exchange that for upper body excercises on a 27" screen?

I ordered one to see what it can do. I think it's got a lot of possibilities, but I'm actually going to try it before deciding.

I just put an order in for one. Looks interesting as heck. I saw a
preview of this quite awhile ago, but didn't know it was so close to
being reality. Accurate to 1/100 of a mm. That's quite accurate!

Don't know if I'll ever be that accurate! I wonder what they'll use for
a virtual keyboard being as they say their device replaces mouse and
keyboard!?
Watched a couple of videos on YouTube tonight on the system and it seems
OK, but they mention an app store dedicated to their device/system. Uh
Oh! More money!
At one point, the CEO/Founder said that it would work well with anything
designed for touch...i.e. Magic Trackpad. Then, in another breath, an
app store is mentioned.
Wonder what we've gotten ourselves into here!

We replaced a functioning Netgear G router with the Edimax br-6574n router
to obtain more signal strength in May.
OWC touted this router as being a fabulous product. After research on-line,
we discovered only good reviews and ratings, and was highly recommended by
both the manufacturer and OWC.
The set up guidelines do not include any info for Macs, and the tech at OWC
would not assist us.
We googled on line to obtain assistance from a kind soul who shared his
experiences with mac set up.
The Edimax was set up in May, and stopped functioning in June. Had to be
returned to the manufacturer for replacement (postage paid by us), two weeks
later (1st week of July) a replacement router was sent to us.
The second week of August, the replacement router stopped functioning.
Run from this product if you want a reliable router which will meet your
wifi requirements.
The vendor will not stand by the product, and Edimax will not provide a
refund.
Our replacement is Apple's Airport Extreme which was very easy to set up in
all our wireless devices, and is providing much faster service - reliably.
We should have purchased that to begin with.
I am so frustrated by the lack of customer service by both the vendor and
manufacturer. Warranties may be good, but a guarantee is provided by the
vendor/manufacturer who really has confidence in their products. The Edimax
product is good only for the recycle bin.
Thanks for letting me share,
Donna
