Power adapter issues using MacBook Pro in European countries?

Are there any known power problems with the new MacBook Pro in European countries such as United Kingdom, France or Italy assuming that I use one of the plug adapters in the "Apple World Travel Adapter Kit"?
Also, is it advisable to provide more protection between the electrical source and the computer than what the computer already handles such as a currency/voltage type converter?
Adapter Kit: http://store.apple.com/us/product/M8794G/B?fnode=MTY1NDA2Nw&mco=MjE0NjQ4NQ

The MagSafe adapter is designed to work with 110-240 volts so it's fine to use across those countries with the World Adapter Kit (I have one too). The only issue you might come across is earthing, i.e. you could feel a tingle in your palms when using some power supplies due to lack of proper earth connection.
Your alternative is to take your regular power lead and purchase a plug adapter, then you're more likely to get an earth connection and no tingle.
There's no real need for surge protection but it won't hurt.

Power Adapter for 17" MacBook Pro 2.8GHz (Mid 2009)

I'm curious to know if i can use a power adapter from an older 17" MacBook Pro 2.4GHz (Mid/Late 2007) with a brand new 17" MacBook Pro 2.8GHz (Mid 2009). Both are 85w i believe - but i wasn't sure about the new battery with this new computer.
Thanks

i would like to say, power adapters are of no tricks. They just provide voltage, current, and also the quality of them. When i say quality, it means how stable they can provide. All good functioning power adaptors should have an acceptable quality. So this is not a concern.
Then, what is going on with the "power"? No matter how many watts, there are _*no differences*_. What you have to consider is: unless it cant boot up your system, or it is not capable to charge while you are working (lower watt will just charge slower), or it has some serious problems when you are doing some high energy consuming tasks (like playing 3D games, video converting). Otherwise, the power adaptor is said to be providing enough power, and nothing to be worried about =]

This sounds like a hardware problem that will likely require a 'hands on' approach. Hopefully there is an Apple Store Genius Bar close-by
Find your local Apple retail store and make a reservation through the online Apple Store Concierge. Reservations are REQUIRED

Replacement power adapter for 2008 MacBook Pro

Does anybody know if you can get a replacement power adaptor for the 2008 MacBook Pro. Mine crapped out and I'm freaking because the one they have for sale does not look like it will work, help PLEASE!!!!

If I think I know what your saying, it sounds like the store only had the Magsafe 2 connectors for the new model Macbook Pro's. The good news is yes stores still sell both Magsafe 1 and Magsafe 2 adapters. My advice would be to just take your adapter into the store and show the sales person what you need.

When i connect the power adapter of my MacBook pro 13... my laptop automatically switches on ...how to fix it..tnx

plzzz help me... i think my battery is also gone..its been only 193 cycle count out of 1000....now count no is also not showing..plzz help me..

For power related issues such as yours, the first step should be to reset the System Management Controller.
Best of luck.

How do I fix the power button on my MacBook Pro?

How do I fix the power button on my MacBook Pro? Thanks to Apple, if you accidentally hit the power button with Mavericks, your downloading, ripping, burning, saving and any other process will be halted without completing. How do I fix this so this no longer happens?

Which os version are you using? Which model Macbook Pro do you have?

Using MacBook Pro abroad

Hi,
I have recently bought a new MacBook Pro with Retina display 13" in Australia and I'm going to Sweden for a while. Do I need to buy an adapter/converter ? Or will a simple plug (the kind you can get at an airport) do? I have plenty of different plugs/adapters for various countries but I don't want to fry my computer the first thing I do when I get there..

You should not need a converter, just the proper 2 prong style Euro adapter. The Macbook Pro power adapter is scaling, going from 110v up to 240v. You were just using 240v in Australia, Sweden power outlets should be 220v, so you are still safe. I have included a photo of the standard Europen style outlet you will encounter in Sweden. Happy travels!

Is it dangerous using macbook pro while charging?

Hi,did anyone experienced any electric issue when using macbook pro unibody while charging?When I use it during the recharge process the electricity pass trough my body.I can say that because one day when I was using it (with the hands on the keyboard) my girlfriend came and touched my face moving her hands on my cheeks and I felt a weird sensation like a vibration on my face so I unplugged the power cord leaving the hands on the keyboard (with palms near the trackpad) and I didnt feel it anymore.It is known that the electric fields can cause cancer.Am I in danger?I don't think it is a good thing that electricity pass trough my body anyway.There is any way to fix this problem?(a part of not using it while connected to the wall charger).Thank you

Some people are more sensative to EMF's then others. If there is a bad connection in your house or in your computer, then you may experience this more then others.
My guess is your house may have some faulty wiring somewhere and needs to be addressed. Get an EMF detector and see if you get spikes in the area of where your plug in your computer. Or rather, call an electrician who can check for these spikes around your house. Some houses, especially older ones, will have electrical problems, but even newer ones can have these since someitmes the laborer who installed it didn't know what they were doing or didn't bother checking.
get a surge protector for your electronics, especially your computer deivces.

I'm trying to reinstall Mavericks on used Macbook Pro. When I log in to my Apple ID, it says it was not the same ID used to purchase Mountain Lion. I need to change user/admin as a lot of the folders and apps are in Chinese!

The first thing you should do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. How you do that depends on the model. Look it up on this page to see what version was originally installed.
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, which you can get 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. I suggest you 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. If you don't have the media, 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.
Once booted from the disc or in Internet 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, which is what you should do.
After partitioning, quit Disk Utility and run the OS X Installer. 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.
You should then run Software Update and install all available system updates from Apple. If you want to upgrade to a major version of OS X newer than 10.6, buy 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 toauthorize it under your ID. In that case, contact iTunes Support.

Bought Used macbook pro, don't have administrator password and don't have the OS disc. Is there a way I can reset or delete the password?

I recently bought a used macbook pro. I can pretty much do everything I need on it until I want to change setting and such things. Then it asks me for an administrator password which I do not know or have. On top of that I do not have the OS disc either. Is there a way I can SAFELY reset or delete the password so I can set my own without the possibility of screwing thing up. LIke I said I can do most anything. I figured this out when attempting to tether it to my smartphone for internet access (I do all the time from my desktop but my desktop is a PC so things are a little different) I am a very new mac user, I have always been a devoted PC user until now. I have to say I am really loving my macbook pro I may just stick with mac from now on (if I can get this problem figured out without too much stress.
I am looking for the safest and best way to fix this issue where nothing I do would mess up the laptop. I can use it now and I do not want that to change, I just want to be able to change my setting and set a password of my own. PLEASE HELP, THANX!

Hi
There actually is a slightly easier way in OS X 10.5 or greater.
1. Start up in single-user mode (hold Command-S as the computer starts up).
2. Type: mount -uw /
3. Press Return.
4. Type this:
passwd (user's short name)
Replace "(user's short name)" with the short name of the user account whose password you wish to reset. If you are not sure what the account name is, you can get a list of user names by typing: ls /Users
5. Press Return.
6. Enter a new user password.
7. Press Return.
8. Type: reboot
9. Press Return.

Where can I get an additional power source for my MacBook Pro?

I am travelling to Europe next week and will be travelling on the road quite often. I would like to get some work done during that time. My laptop battery will inevitably run out of power during that time and I would like to carry an additional power source with me so I can get some extra juice when I am nowhere near an outlet.
I have the latest MacBook Pro where the battery is not removable.
Where can I get an additional power source for my MacBook Pro? I don't mind if it is a 3rd party product.

you could get something like this: http://www.amazon.com/Energizer-XP18000-Universal-External-Netbooks/dp/B002K8M9H C
it's about the same cost as an extra battery used to be. there's a range of similiar products at Amazon, i'd check reviews.

I bought a used macbook pro with 10.9.5 but it didn't start up clean. There are a lot of programs etc. How do I know if it's ok to use?

I have a macbook pro that I want to give to my son for school. I just purchased a newer (used) macbook pro with more HD and memory to replace the one I use for work. I need to set up the new book and transfer all my stuff over, then clean the older one up for my Son. I'm concerned because the newer book I purchased on ebay. It didn't start up a if it were a clean machine. I turned it on and it is full of lots of programs and I'm worried the previous owners files and information are on the computer. They both have the OS X 10.9.5 (13F34) software.   I updated to the new iLife on the older one, the newer one has 09. I would appreciate the steps I should take. I have everything backed up on the older book through drop box and cloud, so I'm ready.   Also the seller told me the computer would have Mavericks already installed, but I don't see it.

Before buying a second-hand computer, you should have run Apple Diagnostics or the Apple Hardware Test, whichever is applicable.
The first thing to do after buying the computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
How you go about 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.
It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
1. If you don't own another Mac
a. 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 is very old and 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.
b. 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 a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in 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.
d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
2. If 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 prepare a USB device, then start up 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 start 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.
3. Partition and install OS X
a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
b. 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.
c. An unusual problem may arise if all the following conditions apply:
          OS X 10.7 or later was installed by the previous owner
          The startup volume was encrypted with FileVault
          You're booted in Recovery mode (that is, not from a 10.6 installation disc)
In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart 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.
e. 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 original 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.
4. Other issues
a. If the original 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 irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
b. 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.
c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.

[SOLVED] Linux kernel 3.6.2-1 issues on Macbook Pro 4,1

After my recent system upgrade to linux-3.6.2-1, I ran into a couple noticeable issues on my laptop. The first was the inability to use "mount -i /home/user", which is in my .bash_profile, to mount my encrypted home directory at login. An error message would respond saying that eCryptfs does not support aes. I was able to manually mount it with "mount -t ecryptfs /home/user/.private /home/user", but could not figure out the issue. I also noticed my laptop running a hotter that usual and found that my fans were not changing according to the sensors. I use macfanctld from the AUR to change my fan speed and killing its process and restarting it had no effect. I then decided my recent system upgrade may be at fault so I rebooted into linux-lts and the issues were solved. I then downgraded linux-3.6.2-1, linux-headers-3.6.2-1, nvidia-304.51-4, virtualbox-guest-modules- 4.2.0-6, and virtualbox-host-modules-4.2.0-6 to linux-3.5.6-1, linux-headers-3.5.6-1, nvidia-304.51-3, virtualbox-guest-modules-4.2.0-5, and virtualbox-host-modules-4.2.0-5. These issues are now fixed on my system with the downgrade and I have blocked them from upgrade in pacman.conf. I did not notice any other issues.

I felt it was necessary to post this issue, especially if another person also has it, so that it may be resolved in future kernel updates. If there are any logs or other information people need to help resolve this issue or if I should notify a mod of this or something, please let me know.

After further investigation the issues were easily solved.
Regarding my encrypted home directory, I checked kernel.log and found that ecryptfs did not like the argument ecrypt_key_bytes=16 and that manual mount has the variable name ecryptfs_key_bytes=16. So I simply changed that in my fstab. Auto-mounting my home directory works nicely again.
In regards to the fan issue, I had to alter /etc/macfanctl.conf because the output of the sensors command (lm-sensors) contained some negative values which may have affected average temperatures and such. I excluded those temperatures and played with the constraints more until the fans spun faster when I felt they should.
Still found it strange that some of these issues happened during kernel upgrades, but glad to have solved the issues.
