US MacBook power supply in Ireland
I'm heading to the states next week and thinking of buying a macbook to bring back to Ireland with me. Is there any problem with the power supply's or are the a univeral voltage.
I know that I'll have to get a different adapter for the plug but is that all?
Mick.
ackd, It will work fine, they are multi-voltage, you will just have to buy a local power supply for your MacBook.
Taken from the spec. page on Apples site:
Electrical and environmental requirements
* Meets ENERGY STAR requirements
* Line voltage: 100-240V AC
* Frequency: 50Hz to 60Hz

Macbook power supply for MBP?
Is it possible to use MacBook nice and compact power supply for MBP?
ThanksActually they are the same size. I have a 85W adapater and it pops right into the power connector on my MacBook. I did not have the MBP adapater plugged into the wall socket though. The pin spacing and arrangement appear the same also.
The MP adapater lists the output as 16.5 VDC, the MBP lists two output voltages; 18.5 and 16.5 VDC.
I am NOT going to try and charge or power my MacBook from the MBP adapter, but I think it would be short sighted on Apple's part to use the same connector on both adapaters if using the wrong one could damage either the MB or MBP.

Macbook power supply broke after 90 days
my power supply broke, as confirmed by best buy and the apple support rep on-site. I need to order an exchange because it is still under warranty, but cannot figure out how to? We bought extended warranty but apparently it is not yet needed, just the regular hardware warranty since laptop is so new. How do I order a new power brick?
thanks for response. I have 7 series too. I went to bestbuy and they said to order a new power adapter from Apple care online, but I cannot seem to find out where to do that. There is no authorized Apply shop nearby. So ideally I would order a new power suplly under warranty and they will ship it.

I just recently purchased a black macbook from the Apple store in Japan. I have a apple travel adapter kit, but what I was wondering is this, can I use my 17" powerbook G4 prong cable with the macbook's magsafe brick? The prong extention cord that comes with the macbook here in Japan only has two prongs.
Powerbook G4/MacBook Mac OS X (10.4.8)This part isn't rocket science - if it fits, you can use it.
I just switched the cables between my 15" PowerBook and MacBook. They look the same, fit the same, work the same. -
MacBook Power in Japan ???
My daughter & her boyfriend are off to Osaka, Japan with his new MacBook in a few weeks.
Power over there is 100 volts, and 50 Hz in some parts of the country, including Osaka, & 60 Hz in others.
Any warnings about how to use or not use the MacBook power supply to protect it from possible harm ??
MI guess you have nothing to worry (at least for the magsafe), since it built for those voltage range 100 v to 240 v and 50 hz or 60 hz.
Just use proper socket adapter to connect it to their native power outlet if it differ.
Good Luck. -
Can anyone tell me if my UK MacBook power supply will work in the USA? I know I need an adapter to fit the American plug socket, but do I need a transformer?
Nope, the mag safe have voltage range to cover us and uk voltage.
Good Luck. -
i bought my macbook pro in the US. can i use it in china? (P.S the power in the US is 110v, in China is 220v, however, the mac power supply has said: "Input: 100~240v")
The Magsafe autoswitches based on detected power. You will likely need a wall adapter to alter ther US-based 3-prong to whatever is used in China.

I am new to the Macbook community. I own this Macbook since 10/2012.
My Macbook Pro 15 with Retina Display suddenly totally stopped responding. No display, no activity on keyboard. When I connect power supply cable, the Mac makes a noise as if it is starting up, but this lasts a second and this sound comes and goes the whole time the power cable is connected.
Any advice?
Thanks!Reset the SMC and the NVRAM:

I have a macbook air (mid 2012) and a thunderbolt display (27'').
Do I absolutely need to connect the power supply together with the thunderbolt cable ?
I found that the screen won't wake up if only the thunderbolt connection is plugged. Is this normal ?I just got my ATD and late 2011 MBP up and running. I've not tried running without the power adapter from the ATD plugged in, but I just tried and didn't have any problems with the display not waking. You may want to take your query to the ATD forum - https://discussions.apple.com/community/peripherals/thunderbolt_display - perhaps someone there has experienced a similar issue.
Good luck,

I am moving to New Zealand and want to take my macbook pro with me.
I have a Magsafe 85w power supply.
I am aware of the apple travel kit.
Do i need to purchase this, or is a standard travel adaptor safe?
Do i need a lower watt magsafe power supply?
Should i get a grounded 3 prong adaptor rather than the ungrounded 2 prong adaptor that comes with the apple travel kit? Particularly with long term use.
Thank you all!The item that is crucial is the connector to the AC outlet. The power adapter will work from 100 to 240 volts.
Ciao.
A grounded plug is always preferable.

Macbook pro,power supply is very hot?
macbook pro 15zoll with retina display, power supply is very hot! is this normal??
It depends on what you are doing. Yes, the power supply can get hot. This is normal.

I use a 27" Thunderbolt display on my macbook pro. If I disconnect the power supply from the mac, the monitor stops working.
Is that normal or do I have to make some changes on the setup ?
Thanks
+GLGreetings koningsvaren,
Welcome to the Apple Support Communities!
I understand that you connect your MacBook Pro to an external Thunderbolt display and everything works as it should while connected to power, but once power is removed from the MacBook Pro, the second display no longer functions. It sounds like you may be using this configuration with your MacBook Pro closed, otherwise known as closed-clamshell mode. In order to use a second display with your Mac portable in closed-clamshell mode, the Mac portable must be connected to power. Please refer to the attached article for more information. If this is not the case, please let me know.

Will daisy chaining two bus powered external devices put too much strain on my 2011 MacBook Pro 13" power supply? Specifically I would like use ProTools with a LaCie bus powered hard disc and a Digidesign Mbox 2 Pro which is also bus powered with firewire.
Hi rrlavigne,
The biggest difference between the two machines in maximum RAM capacity. The white MacBook is limited to 4GB, whereas the MacBook Pro will support 8GB of RAM. While the cost of RAM is prohibitory right now (to go to 8GB), to have that flexibility in the future will very much be worth it... especially considering you intend to install Logic.
Other than that, I think in terms of "raw performance" the machines are very equally matched. You're paying for the unibody design, backlight keyboard, SD card and new battery technology for that $200 premium (in addition to the slight CPU bump). -
My MacBook Pro will not powerup (even when connected to power supply).
My MacBook Pro will not powerup (even when connected to power supply). The caps lock key is the only light on.
Hi PatB11902,
Thank you for visiting Apple Support Communities.
If your MacBook Pro does not seem to power on, but the caps lock key will light up when you press the caps lock key, you are likely seeing a video issue.
There are several steps that can help troubleshoot this behavior, found at this link:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
Start with these steps:
Reset the system
You can reset the Mac's parameter RAM and SMC.
Start up in Safe Mode.
If your Mac does not start up normally after these steps, here are some additional tips that can help:
Troubleshooting: My computer won't turn on - Apple Support
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.
If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).
Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).
Sincerely,
Jeremy
