Old problem-- Electricity leak while charging MBP retinal display

I know this problem happened for long time since the early version of MBP. There is electricity leaking on the metal part of computer while you plug in the adaptor because the earth line is missing. If you use the extension cord, the problem is gone because the earth line is available in the extension cord.
I just want to know if Apple is aware of this and had produced a adaptor plug with earth line yet? It has been so many years and MBP is updating for few generation already!

Whether Apple is aware of it I don't know but they are not going to change the transformer 2 prong plug to a 3 prong. It wouldn't fold in if they did.
I believe this is specific to certain mac notebooks. It doesn't happen on mine. Could be a missed placed or missing piece of insulation that shields the logic board from the case.

MBP retina display wallpaper problem

I just bought the MBP retina display and somehow the OS doesn't save my wallpaper. It will go to the default Mac wallpaper whenever i restart my computer. Is there a way to solve this?

Alright no worries, I felt it was worth while looking at, although the unit is 4 days old in your hands, the software was likely installed longer than that, at the distribution centre.
The next step we would likely do, is remove the com.apple.desktop.plist file to the desktop itself, this will encourage the operating system when restarted (or logged out) to regenerate a new file in its place.
Although this is such an evasive step, and should cause no problems, since it is a user specific file, I do feel the need to tell you to backup any data first, and make sure you have everything covered before proceeding.
I would expect nothing to go wrong in this process, honestly , but whenever a solution comes down to replacing files the operating system has in place, its worth covering. If you are satisfied you have everything backed up, and wish to proceed, the next steps are as follows:
1) Open up a finder window, you can do this by clicking the square face symbol on your dock (half dark blue, half light blue). You should have a finder menu bar running across the top of your screen, and 'Go' should be listed.
2) Select 'Go' and this will drop down a list of places your system can go to. Hold down the Option (alt) key on your keyboard and this will show the hidden 'library' in your drop down list. Select library.
3) The finder window will now show the contents of your user library. Find a folder called preferences in that folder and go into it.
4) You will now see many com.apple.xxxx.plist files. Find a file or files beginning in com.apple.desktop (com.apple.desktop.plist is the common one, but sometimes there is com.apple.desktop lockfiles also) and drag them to the desktop itself, make sure the files are actually moved to the desktop and not just copied.
5) Once the files are moved to the desktop, and no longer exist in your preferences folder, restart the computer, and try again. The computer at this point would have generated replacement files.

Getting electric shock while charging my i touch

hi
i am getting electric shock while charging my itouch

Also, do yo get it when charging with a wall charger?
A computer USB port?
Could be a problem with the cable (as mentioned by kylewont) or the charging source or the iPod.
An appointment at the Genius Bar of an Apple store maybe in order.

IPhone 4 getting electric shock while charging

Hi I am getting electric shock while charging my iPhone 4

You may have a short in the USB cable or charger, try a different cable if you can. I shocked myself on a frayed iPhone cable and switching it obviously fixed the problem

My 2 month old nano only works while charging, i've tried resetting it and still the same.

You are still under warranty. Either call iPod tech support - U.S. iPod and Mac technical support: 1-800-APL-CARE (1-800-275-2273) or take the iPod Nano to an Apple store or an AASP. Whichever is more convenient for you.

Problem with MBP Retina Display battery

So, I'm on my second MBP Retina Display. The first one had a dead pixel. However, other than the dead pixel I was pleased with the laptops condition.
I got it replaced. The new model seems to be having issues with burned in windows on the display. Also, the battery life seems to go down much quicker than
the one I had originaly.
I took my laptop into the genius bar and was told the battery was completely fine but because I used migration assistant something was draining the battery life.
A month has gone by since I cleaned out my laptop and didn't use migration assistant. The battery had been lasting longer than before. But now it's draining rather rapidly again. I don't know why.
Also, I hadn't noticed the burn in's until now.
Can someone tell me if there is a way to fix these issues? Or if I should take my laptop in again?
Thanks for the help!

Having problems with my new usb superdrive in my MBP retina display.

I just bought an apple usb superdrive for my new MBP retina display. I connected the usb superdrive to the MBP and I was going to install a program but doesn't appear in the desktop or neither in finder. The disk is still inside the usb superdrive! The MBP doesn't recognize the usb superdrive. What do I do now? The disk is still inside!

With the system turned on Disconnect the superdrive and then reconnect it. If that fails try the other USB port, the one on the other side.
If That Fails take the system and the superdrive to the Apple store you bought them from and have them fix whatever is wrong with either the drive or the system or both.

Audio issues with some full screen applications (game) and teamspeak with a 15" MBP retina display

While trying to play League of Legends in the lobby and loading screens i can hear everything but when i go in game i cant hear anything, and with teamspeak my teamspeak cant detect the input or output devices and i can hear everything else like skype and everything
Already reinstaled flash restored the system and took it to the apple store, this happened like for 2 days with youtube and they solved that but not the problem with the game or teamspeak

Apple doesn't offer the option of full resolution (2880x1800) and says everything other than 1440 x 900 won't look as good as 1440x900.
so while you can set the monitor to 17" resolution (1920x1080) it has to simulate it on a 2880x900 screen and has to blur and reinterpolate elements to make it work
they've really messed it up for anyone wanting true HD resolution for professional reasons.
Indeed. Everything except 2880x1800, which is unavailable without SwitchResX, and 1440x900, which comfortably fits one pixel of the image into a four pixel square of the Retina Display, must be simulated or scaled. However, while the scaling is real, the 17" "simulation" looks as good, to my eye at least, as my wife's MBP 17". Going smaller will test one's eyes probably as much as Apple's scaling algorithms so the tradeoff for greater screen real-estate may turn out not to be as bad as we'd think. All I need is a MBP Retina Display and SwitchResX to find out...

Late 2013 MBP Retina display stains

Late 2013 MBP Retina display stains, getting worse.
I am always very carefully with my mac, still the display always looks smudged. Even when I just close the lid, for transport, I have like the keyboard printed on my display when I open it again. Now I discovered more and more light spots which can't be wiped of at all.
There is obviously a problem with these retina displays.
I am very disappointed I have to say. I'm out of warranty but I can't believe that I pay € 2.600,- and get a display like that!
Please Apple, do something…

While booting the apple logo is purple and the the grey screen turn yellow for a second.

Screen real-estate on the 15" MBP Retina display

The 15" MacBook Pro Retina Display has a remarkable 2880x1800 pixel resolution, compared to the 27" LED display's 2560x1440. Normally, screen real-estate is defined as how much stuff (windows, menu bar items, bookmark lists, etc) you can fit on the screen, with a larger (that is, more pixels) screen being able to show more stuff using its native resolution.
With the MBP's Retina display, the pixels are so small that using its native resolution in the same way as with the 27" monitor should result in, say, really small menu bar items, etc. As a result, the default monitor setting involves scaling, so that something which might normally take up one pixel might get four or eight devoted to it, making it larger and easier to see. Its monitor control panel allows changing that relationship so that everything could be made to appear even larger, resulting in less screen real-estate, or smaller, resulting in more screen real-estate; i.e., lots more stuff can fit on the screen.
My question is whether, at the smallest setting offered, the screen real-estate is the equivalent of, say, a 32" monitor which also has 2880x1800 pixel resolution but is spread over a much smaller physical area, or is the Retina's display still scaled to some smaller equivalent resolution because straight 1 to 1 would simply be too small to be practical? If that's the case, what does the effective resolution work out to be at the smallest setting?
I'm aware that's not a simple question because, for example, I understand that an HD Movie could be displayed pixel for pixel even if everything else outside that window is scaled. Moreover, the use of vector graphics complicates the matter further. But for things like menu lists and word processing documents, can the MBP's Retina display be set to what we understand to be 1 to 1?

The main error in this position is thinking ANY sized SSD can be "storage"
Any Macbook SSD should be idealized as a working platform computer system, containing all your applications, documents, and weekly-use necessary files; and all media files such as ‘big-data’ (music/PDF collections/video/pictures), unless directly needed in the near future, should be kept off the computer and on external storage USB or likewise bare hard drives.
You cant do what you want without removing the internal SSD
Officially, it is not possible for an end user to upgrade the storage in any Retina Display MacBook Pro model after purchase

Current leakage/electric shock while charging

I just own the Macbook Pro Retina Display for a few days and everytime I'm trying to charge it with the supplied charger, the metal casing has feel of electrical shock! I encountered this at all location regardless of power sources, from various countries in hotel and at home.
If I use the power plug adapter that has 3 pins adapter with extension cable, it will eliminate the problem as it has ground contact on the adapter. However, the 3 pins or 2 pins adapter that direct attach to the power adapter without extension cable does not come with ground contact. I would not want to bring the extension cable everywhere.
I approached Genius Bar but was told that it is normal. I couldn't accept the answer as this "normal" condition is greatly impacting Apple product user experience! I'm ok if Apple could replace my 3 pins adapter with a grounded pin and stay with the problem with 2 pins but not asking me to accept the fact that "it is like that, we can't do anything" or a defective product.

Hi Casper-Tech
I am also the owner of the new retina display macbook pro and just few days after the purchase, i realised that it passes me electricity shock whenever I glide my fingers on the aluminium chasis body, especially the metal next to where we plug in out power (below the screen).
This happens when I use the 3 pin plug directly to the magsafe 2 whilts this problem is gone when I use the extension cable.
I have contacted Apple Care and they also said that this EXTREMELY WEIRD phenomenon is normal with the 3 pin plug as there is no grounding on the plug while the extension cable does have it.
I also realised that there is a difference between the 3 pin plug and extension cable, the latter has 0.5 A less fuse compared to the extension cable. Maybe this has caused the leakage of the electric current.
Meanwhile, I just intend to bring the machine and the plug to Apple Service Centre to have it look at and check whether there is a damage on my macbook pro.
If you feel unsatisfied/uncomfortable with this issue, you can get yourself a 3 pin plug with higher fuse rating or you can ask for a refund. That was what the Genius Bar suggested me.
Cheers. I bet there are many people with this problem but they just don't realise it yet.

Satellite Z830-10 - electric shock while charging

I've recently bought a Toshiba Satellite Z830-10 from PC World UK. I'm experience constant electric shock when my wrist touch the laptop body while charging with the adaptor. No problem when it is on battery.
Does anyone having similar problem?
After some research on the internet, there are some report about laptop with metallic casing when the manufacturer supply with 2 pin plug which does not have earthing.
Other company have replaced their problematic laptop with 3 pin plugs for all their customer. My adaptor is indeed with 2 pin plug.
Could the shock by lack of earthing in this case similar to Dell problem?

Hi
I would really recommend contacting the Toshiba authorized service partner in your country to check the parts and to fix this issue.
A friend of mine is an Z830 owner but as far as I know he did not experience any similar issue.

Feeling electric shock while charging Mac book Pro

Hai everyone!
i just bought a Mac bookPro 15 inch 2.53 Ghz.
i am feeling a mild tingling/ vibrating shock while charging my mac book pro. i can feel the sensation all over the aluminium unibody part- especially while using the Mac book as well as charging it at the same time. is it Earthing/ grounding problem? or is it any voltage problem? or is it any problem with my Mac Book Pro?
Thanks and Regards

"I bought my laptop from the US, but i am using it in Spain , with the aid of a plug converter (3 pong to 2 European one)...
"1) is this problem i am experiencing due to the plug converter?"
Yes and no. Outside of the US, the AC line voltage is twice as high, and that's why people outside of the US generally experience the "shock". If you use a 3-prong plug adapter inserted in a properly-grounded AC outlet, the problem will be resolved.
"2) I am staying in student resident, and so i doubt that the MBP is not properly grounded.. That would be dangerous, no??"
If you are using a 2-prong prong adapter, your unit is not properly grounded. Using an improperly grounded computer is not dangerous.
"3) Aside from being extremely annoying sensation, is it bad for the laptop??"
No.
"Because if not, i can always use another keyboard.."
You mean, "if it IS" a problem , you can use another keyboard. Using another keyboard is does not change the grouping scheme of the computer.
"I am not saying whose fault this is, but i only felt this shock with the mac book pro (15 inch).. i owned a power book and a 13 in mac book, and never felt a shock like this before... Could it be because of the placement of the battery on the laptop?"
No, it's because you're using a metal-cased computer, at a high AC input voltage.
