Intel Mac :: 27 On The USB Cable And Electric Current Passing Over?
Jun 29, 2012
Guys, I have touched on my iMac 27 on the USB cable and I have got an electric current passing over me. My feet were naked. When I got my shoes back the problem gone. Is this normal? Is it safe for my iMac and external devices?
I was an owner of a white macbook for just over a year until the motherboard decided to give up the ghost... So I eventually bought myself a new 13" Macbook Pro. Everything was going just beautifully, until I realised when I was charging it, I had this weird electrical current going through all the aluminum.First of all the first two things that came to mind was. What's the computer and most importantly MY health going to be like if its exposed to all this! Anyway. I read a few threads, and they were talking about the "Grounding" problem. Luckily I got my old macbook charger out and plugged it in.. The problem went! So I was then thinking on where in the charger lied the problem? So I took the cable part from the Megasafe to the socket from my macbook, and then put it into my macbook pro Megasafe... and everything worked brilliantly! I'm no genius, however if you guys feel that tingly electrical/static current going through you're MBP, go and buy yourself a new cable. However as Apple is so popular, I'm sure if you try one of you're friends (As they will undoubtably have one) and see if it is that the problem. In anycase, I'm very happy with my Macbook Pro Apple make some awesome products. Bill Gates should just pack up and go fishing if you ask me. He can never compete with Me old mate Steve
I recently traveled to Europe with a MacBook Pro, and plugged it into the outlet with a travel converter. My understanding is that the brick on the magsafe cable works as a transformer and it is safe to plug into a European outlet. I've never had a problem with other laptops.
Everything worked fine with the machine, except I could always feel an "electric" sensation through my hands when touching the aluminum case. This was especially apparent when running my fingers across the top -- it was as if I could feel an electric current running through the case.
This seemed harmless, and I ran the computer without fail during my time abroad. My question is out of curiosity -- is this sensation normal? What exactly is it?
This is probably a silly question, but I was wandering if it was possible to pass audio from the line-in on a MacBook Pro directly to an audio output? I was thinking of buying a PS3 and connecting it to my external monitor, and thought I may be able to play sound through my soundsticks rather than buying more speakers (budget is an issue!).
I know this used to be possible in the "Audio MIDI Setup" application bundled with the system, but I can't seem to find the option in the new version (maybe something to do with aggregate devices?)
While doing a fresh install of Snow leopard, we go through the language selection screen and then the utilities screen come up - From the utilities screen, we can launch "terminal".
Is there a way to bypass the above steps and directly launch terminal or any other app, when we begin the installation process? Is there any way to pass parameters to Snow Leopard bootloader during install process?
I just brought a brand new IMac today but could not connect the internet with the cable though the cable does work with other computers. Do I have to change the settings or .....? Or its the problem of the jack?
I have a MacBook Pro running 10.5, and I have a Terminal instance set up that invokes the following command:/usr/bin/emacs -nwI'd like to be able to pass a file name to this instance when I start it up, so that it will open a window with an emacs session that is editing that particular file. In other words, the file name is not hard-coded, but rather, it's passed in when I start the Terminal program. Furthermore, I'd like to be able to start this Terminal session with a specified file name by means of a command-line dialog from within another Terminal session. Can anyone suggest a way to do this? By the way, I'm not looking for a solution that only works with emacs, which I only mentioned here as an example. I'd like to know a general way to pass a specified argument at invocation time to an arbitrary program that's associated with a Terminal session, and I'd like to be able to perform this invocation via the command line from within another Terminal session.
Figured it would be a little lighter to have a thread that shows that Apple's computer CAN and DO work occasionally....Here's my uptime on my i7! It wants me to reboot for Safari update, but I refuse. As of 8:42am PST, March 16, 2010:I guess currently I have the longest uptime of anyone in this thread!
I have an iMac white intel-based dual core2 which has been sitting untouched since purchased Sept 2006. Trying to upgrade everything.
When I try to upgrade to Lion it says I need Snow Leopard first so, using Safari, I try to buy Snow Leopard and Safari crashes. Safari is 3.0.4. So I try to upgrade Safari but it says I need Snow Leopard first.
After I moved from my old house to my new appartment, my 24" late 2006 iMac instantly started making this annoying high pitch noise. I've tracked it to coming from the area around the hard drive fan.
I believe there might be a problem with the ground connection in the electricity system in the building. Is there a way to measure the current running through my dear iMac?
ps.: also see my previous post where I tried to figure out what might be the problem.
I have a late iMac 2013 and have had problems since day one and always just assumed it was bad RAM as i upgraded to 16GB, from 8. I finally took the RAM i purchased out and have left the original RAM in and still continually get the below error after restart.
I have removed Kasperky via the Kaspersky removal tool but i notice it still references it below? Unusually it seems to be ridiculously unstable when i am downloading any Movies i have purchased from iTunes (the current movie has crashed 4 or 5 times today) or if i am ripping a DVD i have purchased using iSkysoft. I have started in safe mode but that made no difference, i actually think it has gotten worse since i removed the extra RAM.
I tried to partition my main drive and it failed, however it is now saying that 200 gb of space on my main drive is used up. The partition was only for 100 and I have no idea what happened.
I have observed the tech specs on numerous models of MacBook Pro, but it says nothing about 2nd generation processors. I assumed that they did have 2nd gen processors as the image they use to advertise the processor is for the 2nd gen series of Intel core processors. I just wanted to confirm this belief.
iMac OS X version 10.9.4 showing Numbers '09 version 2.3. I installed Numbers version 3.2.2 on August 28, 2014. But Numbers will not permit me to open any documents in iCloud Numbers by a pop-up indicating I need the newer version of Numbers 3.2.2!!!!! When I go to AppStore to do so, it shows I installed it in August and will not permit me to get it.
I also have an iPod with the latest version
Info: iMac, Mac OS X (10.7.5), MacBook OS x (10.7.4); iPad NEW
I took the plunge and got a MBP 13 (5,5) in October. Its all going well except for the same problem that recurs.
The problem is that when plugged in via magsafe i recieve a mild tingling throughout the shell. This first happened a week after I got it but I solved it by using the long lead instead of the smaller plug. But now even the longer lead which is supposed to remove the issue still gives me the same vibration/electric shock feeling. Its NOT minor, I feel it when its plugged in and it hurts! I get a headache when it does this.
The screen saver that this produces are beautiful but is it safe? It works via your computer communicating with hundreds of computers around the world?
I've linked my guitar up to GarageBand and am trying to get a setting which sounds metal like, but at the same time sounds clear and i'm failing. It produces a good sound but its so full of noise its unbelievable.
The guitar has no noise when its on a setting which doesn't have distortion/fuzz or gain on it, but then i don't have a metal sound.
Does anyone have any idea how i can make such a setting?
My mouse wire (or cable, or whatever..) is kind of messed up with the wire showing on the connection to the mouse and basically in the middle of the wire towards the USB connection to the CPU. It's the Apple mouse.. will I get an electric shock if I touch it while it's on? It's kind of sounds funny that I'd touch it but you know ..
I have electrical tape I don't know if that's necessary.
I've hooked my MacBook to my TV, but everytime I connect the charger it trips the electric switch in my house and shuts everything down. Very annoying... This only happens with the Macbook is connected to the TV...
Has anyone had this before and how can `i go about solving this problem?
I have an IMac from 2007 and MBP from 2011. They are mirror images both running latest version of Lion
I back up the iMac to a three year old OWC 500GB external HD with ultra ATA drive. I was backing up the MBP to a similar device. Both machines connected via USB 2 cable. I use CCC to perform backups.
I recently got a new WD My Book 2TB external device that is USB 3. I use it to backup the newer MBP. I have noticed that the backup takes longer with the new drive. I didn't expect the new drive to take longer. Is there some overhead when using a USB 3 device to a USB 2 machine that causes backups to take longer than with a USB 2 Ext. HD?
I want to hook up a second display to my new intel imac--what cable do i need to use?? I have bought 4 now and they are not the right ones. I am trying to connect a 17 inch apple LCD display as a secondary screen for my imac. my goal is to use the imac for vocal recordings ( already set) and the 17 inch for script reading in my vocal booth.
