Is it normal for Kernal_Task(0) to be using 600 MB of real memory?

I was running some diagnostics and I keep noticing that Kernal_Task is using a ton of real memory on my system. I just had the mother replaced (the original fried). My machine (macbook pro, spring 2011) is running pretty hot as well, although Kernal is not taking up a ton of CPU resources.
Here's a screen shot: http://imgur.com/yvAt0

Probably not out of the ordinary. I just checked mine and it's at 574 MB.
Here's a article related to this subject:

If you google "kernel_task memory usage" you will find a lot of hits on this subject.

I have two iphones, different telcos, i am using the same apple id for both - how can i use the 10GB icloud free memory of my new iphone 5?

Thank you KiltedTim!
YES, that is the free 5GB icloud memory for each apple ID. Can I not add the free 5Gb of my second Iphone to my original apple ID (5GB also) as I want to use one Apple ID name on both 2 Iphones? Is it necessary to have a different apple ID for the second Iphone to avail the free 5GB it carries with it?

Not Charge
- See:

iPhone and iPod touch: Charging the battery
- Try another cable. The cable for 5G iPod (lightning connector) seems to be more prone to failure than the older cable.
- If a 5G iPod
Iphone 5 lightning port charging problem - SOLUTION!
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store.

and
try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Is it normall for a Macbook Pro to overheat during browsing web pages?

Is it normall for a Macbook Pro 13" retina 2 weeks old to overheat during browsing web pages ?
i just brought a new MacBook Pro 13" Retina ( Dual Core i5 2.6GHz , 8GB Ram , 512GB Flash Storage ) and i notes that its really get OVERHEAT on the top right side of the keyboard and the fans work loudly when i brows web or play a game ( CSR Racing ) , it get heat that when i touch the top right side of the keyboard ( the aluminum body on top of the bower key exactly ) i cant keep my finger for morethan 10 or 15 second ..
and the battery wont last for morethan 4 or 5 hours while it supposed to last for 9 hours according to Apple.
so guys is this normal ?
Thanks ,

i've did some search on the same issue and it really seems like everyone have it , even thou at apple reseller showroom here in Doha-Qatar the sales man told me this a such issue in the retina macbooks and apple has admit it and you must take it to the service center and change it , while at the service center said a totally different things and that its fine to get heat ..
in meanwhile my way back i pass by another apple reseller showroom and they clearly said if ur mack gets heat u must go and change it ...
im really lost and i have no idea whats goin on here and whom should i listen to .. i hope someone from APPLE support will read this and reply us whats goin on ?

Is it normal for files to go missing from an external hard drive?

I've posted about this issue before but for slightly different reasons. I'm about to buy a new hard drive (the old one is full), probably I'll go for the exact same model, and I want to know if the problem I had described here has happened to Mac users.
I use a Retina MBP with OS X 10.8.4 that also runs Windows 8 on boot camp. At the same time I have an Acer Aspire and what I used to do is download movies onto my external drive with my MBP in Mac - I would also rename the files in Mac - and then connect the drive to my Acer so I could access the movies there.
One day I noticed that some of the files, after I had renamed and moved them to a new folder on the same partition, had gone missing. As I described in my old thread, it was a weird problem because those "missing" files would appear in Windows but not in Mac. But even in Windows when you could see the folders, they were all corrupted as the system indicated to me - the folders couldn't be accessed and the movies wouldn't play.
Thankfully I haven't had this issue again but then I haven't dared to move any of my movies to a new folder either. Not since that incident. I'm pretty sure that I wouldn't have lost those movies and had them corrupted if I had kept them in their original location. Is it normal for files to go missing or be corrupted when you move them back and forth, especially when you use an external drive with one OS (Mac) and then switch to another (Windows)? I've always wondered if this was an issue. I never formatted the drive when I got it, I just plugged it in and used it. That was before I bought my MBP.
I also was unable to delete those corrupted files/folders. Windows wouldn't let me and in Mac, they didn't even show up. I solved this eventually by using Disk Utility to repair the drive.
Now I'm fine with letting my files stay put if that's what it takes to keep them safe and secure, but I'd be more comfortable if I can understand what went wrong all those months ago.
The hard drive I have is this one from Samsung.

Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the Option (alt) key (shift on Windows), then guide it to the iTunes Library.itl file in the moved iTunes folder.
If you put the copied iTunes folder in the default location of Macintosh HD > Users > *User Name* > Music then you don't even need to start with the option key held down, iTunes will automatically look for it there. (Make sure there isn't anything already in the iTunes folder there that you want to keep since you will be replacing it with the one you are moving.)
Longer answers if for any reason you do not think all library files are inside your iTunes folder (changed preferences settings at some point):
iTunes: How to move [or copy] your music [library] to a new computer [or another drive] - http://support.apple.com/kb/HT4527 - a somewhat bewildering and not always easily understandable set of options.
For the record there's this reference for iTunes 11 but it really doesn't strike me as having the specifics you need. iTunes 11 for Mac: Move your library to another computer - http://support.apple.com/kb/PH12168
2011 ilounge article: Transferring your iTunes library - http://www.ilounge.com/index.php/articles/comments/moving-your-itunes-library-to -a-new-hard-drive/ - An article with good background information (similar to the links above), particularly if you are not sure your media files are all grouped for quick answer above. Unfortunately under the single term "transferring library" it describes two very different moves; relocating just your media (not really transferring your library and not recommended unless you really need this configuration), and relocating media+database (really your whole "library"). Make sure you understand the difference before electing to move only media.

Is it normal for someone to have general diffuculty charging an ipad? I see the "not charging" message even when I am using the charger and cord that came in the original box, plugged into a wall socket directly. It is normal for me to plug it in overnight and to see no charge whatsoever the next day. I have never had so much trouble using a friggin charger in my life. It just seems to be exceedingly finicky. What am I missing?

Charging your iPad should not be problematic. It should be an easy thing to do using the charger provided with your iPad connected to a known good wall outlet.
The charging problem you are experiencing is most like caused by:
1. A faulty charger
2. A faulty cable
3. A bad wall outlet
4. A problem in the iPad.
The first three of these are easiest to eliminate. Try a for ends charger and cable. Make absolutely sure your outlet is good. Try other outlets.
If the charger, cable and outlet a proven to be good then the problem lies in the iPad.
Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

Database Version:11.1.0.7
My Standard Manager details Processes=16 Sleep Time=10 Cache=40
Please correct, If there is need to change Standard Manager configuration...
Plz reply soon.
Regards,

Alig,
Standard Manager is running this request, Import Item program request after the completion, creating Item categories for this it is taking time, that is the reason another import items request is waiting for the Item categories program to be completed.You need to find out why the "Item Categories" takes that long to complete.
Do you have the statistics up to date?
Enable trace as per these docs to find out why the request takes that long.

Is it normal for JPWR to .....

Is it normal for power connector JPWR, "the JPWR 12v power connector is used to provide power to the PCIEX16 graphics card" to output power? Without being connected to the Power supply, this 4 pin molex connector powers my case fan.

It is my understanding that the user is concerned over it being able to supply power.
It would and does concern me a little if mine was/is doing the same thing, tbh i ain't gonna try it.
IF this 4 pin molex, which is supposed to accept power from PSU is actually outputting power and enough of it to power 8Cm or 12Cm fan then its getting power from the psu without the 4 pin molex being connected. Which is what i believe the user is concerned with.
The electricity has to be going to that 4 pin from psu thru board trace etc.
Someone with a better knowledge of how power is distributed around board will be able to tell you if this is indeed a potentially dangerous scenario, as i would kind of expect power to get to that 4 pin thru PCB, however i am unsure as i know nothing about the flow of electricity thru a mainboard other than the obvious
So on other words should this 4 pin that is supposed to accept power, be actually outputting power , EG if you plug the 4 pin from psu into this is it accepting power and outputting power back to the PSU thru the 4 pin connector ?

No, that's not normal, should be no more than a couple of minutes. Updating afterwards may take a little longer since it depends on your network speeds.

Is it normal for Iphone 5 to overheat when using 3G?

Hello,
Is it normal for a new IPhone 5 to get overheated when using for 10mins 3G in searching something over Internet, watching a video on you tube or anything else that uses 3g? What could I do? Thanks

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
If the issue is still not resolved, then take it to Apple for evaluation and possible replacement.

Is it normal for my charger adapter to get hot while charging.

Is it normal for your download speeds to drop as l...

I'm getting a range of speeds atm as I'm coming up to my first week. Since Friday it's ranged from 8mbps to 37mbps. Is it normal for it to go as low as 8mbps? Also, my ping has ranged from 18ms to 44ms. Is this also normal?

Thanks for the info, btw.. I had a powercut in my area earlier today, so my internet was down for about 2 hours. Now it's back on, does the 10 day period restart? As I remember the engineer telling me that I shouldn't turn the hub/router off during the next 10 days, but obviously this was out of my control.
