Is it okay to use macbook pro in an airplane?

I am new to the mac community and was just wondering if its okay to use my macbook pro in an airplane. I just want to make sure if there is anything i need to know about before taking it on a plane. Thank you.

Air density and pressure (not absolute height) could be an issue if you were climbing Mount Everst.
Airplane passenger cabins are pressurized to the equivalent of a much lower altitude (less than like 2000 meters/6000 feet), so altitude specs do not apply.

Okay to use MacBook Pro without battery?

Now I fully understand that it is not such a great idea but I wanted to get some opinions: It's my third NuPower battery. All of them have lasted less than a year and failed pretty bad. This one started bulging quite bad and then I couldn't use the trackpad click button anymore (because it was putting pressure on the trackpad / button.) I took it out and the battery started expanding even outside the laptop! I don't consider myself a rough user. I do occasionally reccaliberate the battery per Apple, make sure I raise the laptop off the table etc. to let air pass under. Currently I am overseas and many Apple resellers do not carry the battery in stock. So I have ordered the battery from Amazon. In the mean time, I am using the MacBook Pro directly hooked up to the 240V outlet with the Apple supplied adapter.
I have heard a few people do this in emergencies. But what say you?! Unlike the US 120V, it's 240 Volts here in India! Somehow I felt better with the battery being there to absorb the jolts! but I have had no issues so far - two days. The Mac wakes up, runs, sleeps fine without a hiccup! I am taking extra care not to trip the extra-easy MagSafe adapter
Has anyone done this? Any direct adverse effects caused by running it straight from the outlet without the battery?

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.

How can i copy files from one external hard disk to another using macbook pro with retina display

How can i copy files from one external hard drive to another using macbook pro with retina display?

That's odd - if you open Disk Utility (Applications->Utilities) and select the disk(s), how are they formatted? If you're only going to be used with your Mac, they should be formatted as "Mac OS Extended (Journaled)".

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.

If you look at the User Tips tab, you will find a write up on just this subject:
https://discussions.apple.com/docs/DOC-4053
The subject of buying/selling a Mac is quite complicated. Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
SELLING A MAC A
Internet Recovery, and Transferability of OS & iLife Apps
Selling an Old Mac:
• When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
• Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
Internet Recovery:
• In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
• Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
iLife Apps:
• When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
• Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
• It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
SELLING A MAC B
Follow these instructions step by step to prepare a Mac for sale:
Step One - Back up your data:
A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
B. Clone to an external drive using using Carbon Copy Cloner.
1. Open Carbon Copy Cloner.
2. Select the Source volume from the Select a source drop down menu on the left side.
3. Select the Destination volume from the Select a destination drop down menu on the right
side.
4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
sure to opt for that.
Destination means a freshly erased external backup drive. Source means the internal
startup drive.
Step Two - Prepare the machine for the new buyer:
1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
2, Remove any Open Firmware passwords or Firmware passwords.
3. Turn the brightness full up and volume nearly so.
4. Turn off File Vault, if enabled.
5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
Step Three - Install a fresh OS:
A. Snow Leopard and earlier versions of OS X
1. Insert the original OS X install CD/DVD that came with your computer.
2. Restart the computer while holding down the C key to boot from the CD/DVD.
3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
Optionally, click on the Security button and set the Zero Data option to one-pass.
4. Install OS X.
5. Upon completion DO NOT restart the computer.
6. Shutdown the computer.
B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
Note: You will need an active Internet connection. I suggest using Ethernet if possible because
it is three times faster than wireless.
1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
Utilities window appears.
2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
on the Erase tab in the DU main window.
4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
and set the Zero Data option to one-pass.
5. Click on the Erase button and wait until the process has completed.
6. Quit DU and return to the Mac OS X Utilities window.
7. Select Reinstall Lion/Mountain Lion and click on the Install button.
8. Upon completion shutdown the computer.
*If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

Just bought a used MacBook pro after my previous died. I want to migrate my applications, data, etc from a time machine backup of the old computer to the new. Will this affect, or overwrite the Apps., data, etc existing on the new machine?

Just bought a used MacBook pro after my previous died. I want to migrate my applications, data, etc from a time machine backup of the old computer to the new. Will this affect, or overwrite the Apps., data, etc existing on the new machine?

No. Only those Apps that are not installed on the new will migrate over.

How to load time machine on a used macbook pro

I recently was given a used MacBook pro. My old MacBooks logic board was going and eventually went, but before it did I used time machine to back it up. I want to load my time machine macbook info onto the pro. I cant seem to do this, since TimeMachine just wants to create a new profile for the new Mac on the external. How can I do this? They are both running the OS X 10.8.2
Thanks,
Nate

Just startup in Recovery mode (Command and R keys held down whilst booting) and boot into your Recovery partition. Make sure that your TM backup is hooked up. In the utility menu, select 'restore from Time Machine' option. You'll be able to choose the drive and the latest TM backup.
Good luck,
Clinton

Is it worth to get a used macbook pro

hi, guys.
I am looking at a used macbook pro from early 2009 with configuration
2.66Ghz Core 2 Duo
8GB of DDR3 RAM (2x4GB)
500 GB SSD hard-drive [which advertisement said it was upgraded at Apple Store for 600 dollars]
Nvidia GeForce 9600M GT (512MB) and Nvidia GeForce 9400M (256MB)
17" Hi-Res Antiglare TFT active-matrix
1920 x 1200 Native Resolution
FaceTime HD Camera, Omnidirectional Mic
Slot-Loading SuperDrive
802.11n Wi-Fi, Bluetooth 2.1+EDR
Mac OS X 10.6.8
there's a dent on the right lower corner, which is acceptable.
the reason the guy sell it is that he got a new model.
why I plan to buy it is that I need to implment all kinds of programming stuff. I have a thinkpad with Ubuntu, but its wifi connection is very bad.
Mac is perfet for programmers.
New mac are pricing.
Any inputs will be appreciated. I want to konw
is it worth to invest a 4 years old macbook pro?
if i buy it, what should I check?
seller said 1000 dollars for the machine.
thanks

It's worth 4 to 500 dollars, none of the 'extras' (the HDD and the Ram) make it any more valuable.
How long it will last is speculative, I have a G4 portable that is 8 years old and works fine still, and I have seen Macs die when switched on for the first time so ....
Offer 400, 500 max, if it lasts a year it was expensive, 2 years it was a fair price, 3 years and you got a deal.
One more thing, as it was delivered new wth Leopard or Snow Leopard you must INSIST on receiving the original discs that accompanied it, they can not be downloaded and you will need them.

Have HP 4580 all in one and it worked excellent before Lion. Could print using Windows on desktop and using Macbook Pro.

Before upgrading to Lion on my MacBook Pro I could print on the HP C4580 All in One using HP Desktop with Windows 7 and using MacBook Pro with no problems. I upgraded to Lion now can only print when I shut down and restart my MacBook. If using the desktop or the Microsoft Office on my MacBook it kicks the printer offline and I have to restart my laptop. I called Apple and they said they did not support 3rd party software. I had previously purchased the printer through Apple with a desktop. I installed the new driver from HP and removed it, reinstalled. Guess what, same problem. Can anyone tell me how to make lion work. Apple will not provide help. Have a iPad and with a small app for $7.00 it prints great. HELP

You must work for Apple. Contacted the vendor downloaded their app. Everytime I open Microsoft Office for Mac it kicks printer off line and if I print from a Windows computer (which printer works perfect) it kicks printer off line. If I restart Mac it will print the item in the printer. Don't care what Apple says, prior to loading Lion never had any problems. Sounds as if Apple programers goofed up and just don't want to admit it and correct their problem. Your comments did not solve any problems, asking for help not Apple support.

What to look for when buying a used MacBook Pro? Tips

Here to acquire a few tips on purchasing a used Macbook Pro. I am not graced with an Apple Store in my area, so I must rely on my own sub par geek wit and with the help of yours.
Tips I know.
Checking Battery Cycles and mAh capacity.
Looking for third party applications.
Request the original StartUp/Install Disks.
Checking memory ratios...

Shop your local and nearby Craigslist websites, starting with:

Read this excellent post by frequent contributor JasonFear about buying and selling through Craigslist:
http://discussions.apple.com/click.jspa?searchID=-1&messageID=9958349
Avoid Ebay.
If third-party applications or other software are included, they add nothing at all to the value of the machine unless you are given the original installer discs for them. Otherwise, they are just pirated software that you can't reinstall if you ever need to.

Installing OS on used Macbook pro

I just bought a used Macbook pro, It has no OS and no install discs. What is the best way to install OS? Contact Apple? Is there another option besides purchasing a new install disc? Thanks!

http://www.everymac.com/systems/apple/macbookpro/stats/macbook_pro2.0.html
You have a 2.0 intel core duo. It originally came with Tiger OS 10.4 installed. Your options again are to contact Apple and get replacement disks or purchase Leopard OS 10.5.

I have just purchased a used MacBook Pro. Should I use a virus protection program on this computer? I can get Norton for free through my cable provider. Thanks, funkro

See my Mac Malware Guide.
This issue is more complex than some of the responses you have gotten are indicating. You definitely should avoid Norton, but there actually IS malware out there, and all anti-virus software is NOT "snake oil." Don't listen to anyone who tells you otherwise, as they don't know what they're talking about.
Although you should be able to do without anti-virus software just fine, there are some perfectly good reasons to install it and some good anti-virus apps to use if you decide to do so. Further, even if you do avoid anti-virus software, you need to understand what the threats are so you don't end up thinking you're totally safe and do something you shouldn't.
