Strange feeling in my hand when using the power-book

I have noticed I get an odd sensation in my right
hand when using my 17" powerbook, say after about
half an hours use. Is there some sort of
electrical/magnetic field which could be causing
this? I have also noticed it in my legs when I had
the power-book resting on my legs. I now only use my
powerbook with a seperate keyboard & mouse so I do
not get the strange slightly warm ache in my right
hand. Anyone else notice anything like this? Any
ideas what it is? It is not something from repetitive
typing etc because it does not occur when I am using
the seperate keyboard.
I have frequently noticed that if I run my fingers over the case, even when the powerbook is closed, I get this funny sort vibration in my fingertips. Whenever it happens, I do it several times to try to figure out what it is. So far, I don't have a clue. I thought it might be the disk drive, but I don't think that any more for some reason.
Whatever it is, there is a there there.

Noise on audio output when using the power adapter

I'm a musician and use my mid-2007 MBP 15" in my live rig. When I use the power adapter, I hear a buzz, sometimes accompanied by a slightly louder buzz that cycles on & off about 1x/second. There are a few weird things going on here:
1. The buzz does not happen all the time. That leads me to think it may be noise in the AC line that the adapter is plugged into.
2. The noise is heard when I use both the built-in audio output AND an external USB audio interface.
In any case, when I disconnect the power adapter and run my MBP on battery, the noise goes away completely. I can probably do this on most gigs, but I'm a little nervous since I run a FW drive, an external USB audio interface, and my midi keyboard (powered by USB) so I am putting a little heavier than usual load on the MBP's battery.
As I said, this may be a noisy AC line. Another guess is that it's the PMU inducing noise into the audio circuitry. I'm hoping a simple AC line filter can help me but I thought I would ask here first in case anyone else has dealt with this. TIA for any help!

I had a similar problem and fixed it with a $5 universal travel adapter. Yours might be different but here's my situation. Try it for little cost and see if it works.
I'm also a muso with an iMac running external KRK speakers via USB Mbox2. Previously I had a Macbook Pro and the same audio problem. I've been putting up with a very low volume, high pitch noise until now. I simply plugged the Mac power cord into a universal travel adapter which then goes into the wall. For Aussie users there is an adapter on ebay that will allow a 3 pin Aussie plug to go into female side and has a two pin Aussie male on the other. For US users you can probably get the same although there is a 59c product that will do the trick called a ground lift adapter. Applecare actually agreed this was the best fix and confirmed there would be no problems with power supply or Mac performance. What a gem ! God knows I've looked into all kinds of alternatives that could have cost hundreds instead of $5.

Is there suppose to be a charging light when using the power adaptor?

I just bought the power adaptor for my ipod shuffle 2nd generation. I plugged the adaptor in the wall, connected my usb line , plugged in my ipod and there is no charging light to indicated if the ipod is charging. Should there still be an amber light to let me know if the ipod is charging with the power adaptor or not?

YES! There certainly should... I have an older version Apple Power Adapter (for the iPod Photo) and it lights up my Shuffle's status light.

When using my power adapter, the light is green for a two seconds and turns red.

When using the power adapter for my MacBook 2.1, the little light on the connector is green for 2 or 3 seconds and then turns red. I bought a new adapter, but it is the same thing. It looks like the computer is charging. What's wrong with it.

Nothing wrong. Here is what Macbook manual has to say:
When you first connect the power adapter to your computer, an indicator light on the
power adapter plug starts to glow. An amber light indicates that power is going to the
battery. A green light indicates that no power is going to the battery, which can mean
the battery is fully charged, is not installed, or has a problem. If you don’t see a light,
your plug probably isn’t seated correctly. Check for any debris and remove it. You can
monitor the battery level using the Battery status menu in the menu bar or by
checking the battery level indicator lights on the bottom of the battery (see page 74).

Using the Power Adaptor

Greetings,
When using the power adaptor should I take out the battery?
The reason why I ask this is that I use to have a Sony laptop running Windows 2000 and had continual problems with the battery not holding its charge. I was eventually told by the Sony technicians that once the battery was fully charged I should remove it from the laptop whilst running from the mains.
Thanks in advance

Hello!
You might try posting this in the appropriate Powerbook Forum. We don't know much about laptops here in the G4 Tower forum.
If you have a G4 iBook post here.

Run the Apple hardware test to see what it tells you. Run the extended test when prompted, which can take awhile.

Hi Buterem,
I'm sorry to hear you are having issues with your MacBook Pro since your recent Yosemite update. I also apologize, I'm a bit unclear on the exact nature of the issue you are describing. If you are having intermittent but persistent responsiveness issues with your mouse or trackpad, you may want to try using Activity Monitor to see if these incidents correspond to occupied system resources, especially system memory or CPU. You may find the following article helpful:
How to use Activity Monitor - Apple Support
If the entire system hangs or locks up (for example, if the system clock freezes and stops counting up), you may also be experiencing some variety of Kernel Panic. If that is the case, you may also find this article useful:
OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem." - Apple Support

HT201401 Microphone works only when using the phone in hands-free

Microphone works only when using the phone in hands-free (speaker on) mode. Otherwise, only a constant buzz, accompanied by regular clicks (repeating 2-3 times/sec) can be heard by called persons or when recording a memo. Makes Siri unusable, and cannot make private calls unless in a private area. Does anybody have a fix for this?

Okay I just solved the problem myself..
For anyone that may have the same issue:
The microphone used when recording video, is the little dot next to the jack on top of the iPhone 4S (maybe also iPhone 4, don't know). There was some dirt in this tiny little hole, and I simply just removed it with a very thin needle, and now it works great!

I created a book in iBooks Author using the Photo Book template. When I rotate to portrait orientation, the photo or widget disappears and a table of contents appears with only the interactive media showing.

I created a book in iBooks Author using the Photo Book template. When I rotate to portrait orientation, the photo or widget disappears and a table of contents appears with only the interactive media showing.

Thanx for the prompt response, KT. I have indeed seen that thread, only just after I posted the question.
I have spent hours on the phone with what I now know is a call center in Texas on this question.
I think Apple could be a little more "hands on" with iBooks Author users, and it should also be pointed out that landscape photos will not display in portrait mode.
In my case, I used gallery widgets to display vertical photos, since they look better in portrait mode.
But instead of simply rotating, the page disappears and a TOC of interactive media appears. The gallery behaves as expected when tapped. This is not what I expected, but since the gallery works, I can live with it.
Right now I have "tickets" telling me to "fix" this "problem or to disable portrait mode.
I don't want to disable portrait mode.
Will Apple accept the books if I tell them this is not an "error?"

When using the built in web server, is there a way to specify a different

When using the built in web server, is there a way to specify a different error handler when you try to access a NON .CFM file? Right now I get the standard:
java.io.FileNotFoundException: filename.ext
Is there any setting to override this and direct the message to your own .cfm template? The missing template handler in the CF Admin work only for .cfm files.
Thx

The in-built web server for ColdFusion 8 is JRun. I am on ColdFusion 10, however, and so cannot offer hands-on advice. (CF10 replaced JRun with Tomcat.)
My guess is that you have to modify the file {CF_ROOT}/WEB-INF/web.xml. Don't forget to create a back-up first!
You may then proceed as follows.
1) In the ColdFusion root (CF_ROOT), create the file myCustomFileNotFound.cfm. Give it some content, like
My custom File Not Found page. Current time: <cfoutput>#now()#</cfoutput>
2) Open the file {CF_ROOT}/WEB-INF/web.xml in a text editor. Add the following error-handling specification just before the end tag </web-app>:
<error-page>
<error-code>404</error-code>
<location>/myCustomFileNotFound.cfm</location>
</error-page>
Save the file web.xml.
3) Restart ColdFusion. Test by browsing to a URL requesting filename.ext

Does anyone find that the new iPad Air sounds sort of "hollow" when using the pad?

Maybe I don't know what I am talking about, but I feel like when using the iPad Air, it seems a bit hollow when using the screen pad or basically just using it in general. My last iPad (the latest one before the Air) seemed like it was more quality. Does that make sense?

Yes it does have a slightly hollow sound when you tap the screen. This is because the screen is made a bit differently than the older ones...there's a gap between the layers in the screen, which causes the sound you're hearing...it's completely normal on the Air. I took my Air back tho! It's awesome but just a bit big for my taste. I'm hoping the Mini comes soon!
And I don't know why Kappy is saying the speakers can't do the low frequency so well. The speakers on the Air produce a way better sound than earlier gens..including low frequencies.
cheers

LabView 6.1 crashes now and then when I try to get rid of an accidential starting connection when using the wiring tool.

Sometimes when using my labtop it happens that I get unwanted connections when using the wiring tool because my labtop notices mouse clicks that never happend. Usually you can get rid of those connections by pressing ESC. But unfortunately now and than LabView crashes completely when pressing ESC to get rid of the connection.
How can I stop LabView from crashing in that case?
Thanks for anybodies help!

Yes, I see this problem on both my LabView-Computers but more often on the labtop because of the strange integrated mouse.
Yes, I get an error message but I can't really translate it in english. It says something about memory access to a special address.
I might try reinstalling LabView one day if I have the time. I don't want to try LabView 7.0. I'm afraid it would be great. Unfortunately my boss alreday told me, we don't have money for the new version.
Thanks for your help!

How do I remove an old username from the app store when using the update function

How do I remove an old username from the app store when using the update function.
I purchased my Mac used. The former owners username prepopulates when I try to perform the updated function on the app store. It does not allow me to use a different user name. I have created my own username and password. I have even been able to purchase items from the app store, it's just when I use the update function it does populate with my username. Any help is appreciated.

The first thing to do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. You — not the previous owner — must do that. How you do it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
1. You don't own another Mac.
If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. For early MBA models, you may need a USB optical drive or Remote Disc. You should have received the media from the previous owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
2. You do own another Mac.
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to create a bootable USB device and boot the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can boot from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
Once booted in Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
After partitioning, quit Disk Utility and run the OS X Installer. You will need the Apple ID and password that you used to upgrade. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
Then run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Apple customer service has sometimes issued redemption codes for these apps to second owners who asked.
If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.

When using the spot removal tool, the sampled area is not showing. I fully remember that I am seeing this before--I already had updates of my LR5

Is this just a setting?

Thank you! I feel so stupid -- I did search the internet--maybe not hard enough.
