Is is okay to clean an aluminum MacBook Pro with alcohol?

I have an early 2011 MacBook Pro 13-inch (aluminum), and I am wondering if it is okay to clean everywhere other than the screen (top, bottom, around and on the keyboard, around the ports) with a 70% alcohol wipe.
Also, I am currently away from my home and I forgot to bring the black microfiber cloth that came with the mac, so that does not apply.
Thank you in advance!

I'm sorry, there's some OK stuff in that thread, but there's also some arrant nonsense.
> Alcohol is not good for LCD screens. Technically it is
> considered a solvent.
Really?! Alcohol is a solvent? Wow! Well, hold on to your hats, folks. This will give you a shock. Do you know what else is a solvent? Water. Yeah, plain water. In fact, any liquid cleaning agent you're likely to use is a solvent, otherwise it would be no use for cleaning.
As to alcohol not being "good for LCD screens" -- what then about vendors who recommended a solution of 50% isopropylic alcohol in water for cleaning their screens? (Including Apple for some of its old notebooks -- see the PowerBook G3 Firewire user manual.)
The fact is that there is only one blanket, one-size-fits-all "solution" -- RTFM (Read The Friendly Manual)!
Read carefully the cleaning instructions in your laptop or LCD monitor manual and follow them. What you should use to clean the LCD screen depends on what type of coatings were added to it during manufacture, and you're not likely to know that. My very old Toshiba Satellite says, "You can use glass cleaner on the display" -- and glass cleaners contain ammonia! My not so old Fujitsu Lifebook says I should use Klear Screen wipes -- and Klear Screen is 99% water. And my Early 2011 MBP says, "dampen the included cleaning cloth with just water". When in doubt, use distilled water, because that's the mildest solvent, and hence least likely to do any harm. But that doesn't mean is the best suited for that particular LCD screen.

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.

You will have to buy Snow Leopard:
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order. You also should find it at your local Apple retailers.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.

Late 2008 aluminum Macbook Pro (15in 2.4GHz) using 8GB of RAM

Hi everyone,
I have a quick question to ask, What I'd like to know is why the Late 2008 aluminum Macbook Pro motherboard has a chipset (Nvidia) that can support up to 8GB of RAM but Apple are stating that the system can do only 4GB?
According to NVidia, The motherboard is fully capable of using 8GB of RAM but has been limited to 4GB by Apple and that this can be resolved by a simple EFI update.
The links below show a well known Apple parts dealer running tests on the system using 8GB RAM and claims that the OS X can read it perfectly but the programs will not use more then 4GB of the RAM.
I really don't understand why Apple would limit the system to use only 4GB of RAM and if Apple have any plans on releasing an EFI update.
Thanks for reading guys

Economics 101: So if you want 8GB, you have to go buy a new MBP and pay another grand for the memory. After all, they are in the hardware business, right?

Where to find the best application for cleaning out my MacBook Air with OS X 10.7.5? I've been using MacKeeper but believe it's slowing down my laptop considerable.

How to maintain a Mac
1. Make redundant backups, keeping at least one off site at all times. One backup is not enough. Don’t back up your backups; make them independent of each other. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it.
2. Keep your software up to date. In the Software Update preference pane, you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis. This is especially important for complex software that modifies the operating system, such as device drivers. Before installing any Apple update, you must check that all such modifications that you use are compatible.
3. Don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this stuff is useless, or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
As a rule, the only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Use your computer; don't fuss with it.
Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception to the above rule. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction. Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve.
4. Beware of trojans. A trojan is malicious software (“malware”) that the user is duped into installing voluntarily. Such attacks were rare on the Mac platform until sometime in 2011, but are now increasingly common, and increasingly dangerous.
There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable.
Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must be acquired directly from the developer. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from a web page without your having requested it should go straight into the Trash. A website that claims you have a “virus,” or that anything else is wrong with your computer, is rogue.
In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
5. Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem. While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage consumption and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
If storage space is running low, use a tool such as the free application OmniDiskSweeper to explore your volume and find out what's taking up the most space. Move rarely-used large files to secondary storage.
6. Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

Before you sell or give away your computer, in addition to the steps listed in this support article, take these steps:
1. Run Apple Diagnostics or the Apple Hardware Test. The buyer will do this (or he should), and you don't want to be surprised by the results.
2. Reset the PRAM and the SMC, which might contain personal information.
3. If you set a firmware password, remove it by running Firmware Password Utility in Recovery mode.
4. If you activated FileVault in OS X 10.7 or later, turn it off.
5. If you use Boot Camp, the partition must be deleted.
6. If you created any other data partitions on the internal drive, remove them in Disk Utility.
7. If the machine has an internal hard drive, erase the one remaining data partition with the option to zero out data. An SSD doesn't need to be zeroed.
You can't legally or practically transfer any software downloaded from the Mac App Store to the new owner of the machine, even if it was free. That includes OS X, so if you upgraded to OS X 10.7 or later, you must reinstall an older OS, either from the installation media, if applicable, or by starting up in Internet Recovery mode (option-command-R at the startup chime.) If you installed from physical media, deliver those to the new owner.
If you're selling the machine, or donating it in working order, and it originally shipped with OS X 10.4 or 10.5, then you have the option of installing either from the discs that came with it or from a retail Snow Leopard disc (which you must then transfer to the buyer.) The buyer should understand that if he doesn't get the original discs from you, he won't get the bundled iLife applications or the Apple Hardware Test. Replacements for the original discs can be ordered from Apple.
The new owner will have to redownload any software that came from the App Store, including OS X upgrades, under his or her Apple ID. If you ever updated the bundled iLife applications (Garage Band, iMovie, and iPhoto) through the App Store, you can't transfer those either. The buyer will have to purchase them.
Remove the machine from your list of registered products. If it's still covered by an AppleCare Protection Plan, transfer the coverage to the new owner by following the instructions in the AppleCare Terms and Conditions (under the heading "Transfer of Plan.")

Backing up and cleaning up my Macbook Pro

Hi,
I've been using a Macbook Pro 2.2 GHz Intel i7 for just over a year now and my hard drive is full to the brim. I have recently noticed how much slower the whole system is and so have bought a 3TB Seagate desk top external hard drive and want to back up my whole system and clean up my Macbook Pro. This is the first time I've done this, so I would really appreciate some step by step advice.
I would like to know how best to copy all my files and documents to the drive so I can delete them in vast quantities from my Macbook, knowing that it is all safely backed up and accessible from the external drive. I've also been advised to install extra RAM, which would enhance the speed when running two programmes (Final Cut Pro and After Effects, most regularly). Basically, I would like to clean things up so my system runs as smoothly as it did when first out of the box.
Could you please offer some advice as to how I should go about doing this? Is there a process that I should be following in order to clean up my computer so everything is safely backed up? What other areas of my hard drive that I don't even know about should I be going into to free up space (caches, etc) .The Seagate is literally just out of the box.
Cheers,
Nick

I would suggest using Disk Utility to make two partitions on the Seagate, one the same size as your internal HD, the other for the remainder.
Then use Carbon Copy Cloner or similar to clone your internal disk, so that your Seagate is a bootable backup in case of problems.
Don't worry about caches, temporary files etc - let the OS take care of them.
You could then copy the contents of one of your big directories to the other partition on the Seagate, then delete from the internal disk and empty trash.
But longer term, use the Seagate as backup and internal as working, so I would suggest putting say a 1TB hard disk in place of your Superdrive and moving your bigger directories to that. Now all work is internal, with OS stuff on the original and your stuff on the not-yet-purchased disk, and when you backup (maybe every month for OS stuff, every week or even every day for work stuff) the OS stuff goes to one Seagate partition, the work stuff to the other. You have a bootable clone if your startup disk fails, and a backup of your work. For backing up to the work partition you could consider using Time Machine, so that you have several generations of security from accidental deletes, woopsies etc.

How to slave a Macbook pro with no OS

Helping a friend who just got a (Macbook pro 2) secondhand without any OS installed (HD wiped clean).
He is replacing his current MB Pro that is running 10.4.11.
I hoped a USB to USB would allow the new computer to be recognized as a HD on the desktop of the old one, but that's not working.
How do I get the old one (MB Pro) to recognize the new OS-less one (Macbook pro 2) so that I can clone the old computer to the new. He cannot find any disks in his house after version 9 (!!), so I cannot install another copy of the OS on the new computer and slave it directly.
Any ideas how to accomplish this? Seems like it ought to be easy, but I'm doing this long distance without the computers in front of me, and I'm at a loss.
Thanks for your help.

Connect them with a Firewire cable then Boot the old MacBook Pro with 'T' held down to force Target disc mode (will appear as a Volume on the other Desktop) then you should be able to clone over.

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.

During installation emptied cache, etc. Backed up using time machine, fortunately.

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

Installing Windows XP on a new MacBook Pro with Retina Display.

I just purchased a new MacBook Pro with Retina display and need to install Windows XP on it so that I may run 3 Windows programs. I have watched a few videos on the internet on how to do this through Boot Camp Assistant, and it says at one point to use the driver CD from Mac to install the drivers. I did not get any CD's with my new MacBook Pro. I also saw on some of these boards that said Boot Camp does not support Windows XP. The people at the Apple store said it can run Windows XP, so I have ordered an original version.
Question 1. Does my MacBook Pro with Retina Display running OS X version 10.8.3 able to run Windows XP?
Question 2. How do I install the drivers?

Would this work? And also, what is the VM I need? Where do I get it?

How do I get Firefox on my MacBook Pro with OS 10.8 after two very frustrating and time consuming attempts?

Tried two times to get Firefox browser downloaded to my brand new MacBook Pro with OS 10.8 (Mountain Lion) with no success. First attempt I was using a wireless internet connection. I got through the first couple of steps but then I could not see the Firefox application in my Applications folder. Second time I tried I used a hard-wired internet connection. This time I got absolutely nothing after clicking on the green Download Firefox icon. I patiently waited a full half hour after clicking the green download button but still nothing. What do I have to do in order to get the Firefox web browser on my brand new MacBook Pro with OS 10.8 (Mountain Lion)?

Were you able to download and save the DMG (disk image file) for Firefox?
If there are problems with updating or permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the disk image (DMG) file to the desktop
*Firefox 16.0.2: http://www.mozilla.org/en-US/firefox/all.html
Trash the current Firefox application (e.g. open the Applications folder in the Finder and drag the Firefox application to the Trash) to do a clean (re-)install
Make sure that Firefox gets installed properly.
Open the Firefox disk image (DMG) file and drag the Firefox program to the application folder on your hard drive.<br />
You shouldn't double-click the Firefox application to run it from the disk image, but drag it out of the DMG folder instead.

Macbook Pro with Retina Display to HDTV, How?

Hey , okay so i have the new Macbook Pro with Retina Display i got it not too long ago. I'm looking to hook it up to my HDTV, i have a Samsung TV not 3D and i just wanted to know what cables and such i'll need to help me display what's on my Mac to my tv. I want to be able to use Netflix, HBO GO, etc from my computer and display it over the tv. Even thou i already have it on my 360, i just want the option. Thanks anyways.

We have two Samsung tvs...one is a smart tv and the orher is not but they are both LED. I hook up my ipad to both TV's with an hdmi cable. Did you try all the hdmi ports available? Also, did you change the source on your remote control to the proper input?

Small scratch on my Macbook Pro with Retina Display Screen

I was cleaning the retina display screen of my MacBook Pro when I discovered that there is a very small scratch on the screen. I have had my MacBook Pro with Retina Display for about four months and honestly its my most cared for item. I look after it with every fibre of my being, I am actually a little OCD when it comes to looking after it. I don't even leave the house until I know its in a safe place and nobody else is allowed near it. I am really annoyed that it's scratched and I really have no idea how it happened. I know its only a tiny scratch but its starting to bug me and I am now aware of its presence every time I start up my Mac. Is there anything I can do about this? Is there any way to fix it? Thanks.

For a precise quote, you will have to take the MBP to an Apple store genius bar. If you go to the iFixit.com and Powerbookmedic.com, they will have parts prices which should give you a rough estimate of the costs.
Ciao.
