I want to ugrade my MacBook's memory. Do I need a 64-bit kernel?

I have a model MB467LL/A MacBook5,1 and I want to upgrade its memory to 8Gb and above. Do I need a 64-bit kernel to use this amount of memory? How can I upgrade my model to 64-bit kernel? I know my MacBook's EFI is capable of running in 64-bit mode and I also know that this mode is disabled. How can I enable it?

Not all brands are compatible. That's why I told you to buy memory at OWC or Crucial > http://www.macsales.com Crucial sells cheaper memory > http://www.crucial.com

Welcome to Apple Support Communities
It looks like you have got an Early 2011 or newer MacBook Pro, so you can use 16 GB of RAM. You can buy more RAM at OWC or Crucial. Remember that you cannot upgrade RAM in MacBooks Pro with Retina display
In case you have got a Mid 2010 MacBook Pro, you can only install 8 GB of RAM

I am buying a new macbook pro but i want to fit my own ram memory and solid state hard drive , will apple permit this without voiding the waranty.

i am buying a new macbook pro but i want to fit my own ram memory and solid state hard drive , will apple permit this without voiding the waranty.

yes you can do it and not void the warranty. Those are the only hardware changes that Apple permits. Instructions on how to upgrade the ram and remove and replace the hard drive are even included in the owners manuals for MacBook Pros.

I want to ugrade my memory......

I want to ugrade my memory but upon searching online, it said I can upgrade up to 16GB and in Apple it said 8GB. How do i know what is the correct amount i can install without breaking the bank and making sure I can get the maximum benifit unpon investing into my Mac Book Pro 13in, Early 2011 Model.

Hi Mayelita521,
Some have had success with light projects with the MacBook Air. Check out this article: WalterBiscardi.com | Yes Virginia, You Can Edit Video with a MacBook Air
I'd love to have one for small personal projects.
Thanks,

I want to reset my Macbook Pro back to factory condition because I want to completely eradicate Mackeeper which the previous owner (it is preloved) had downloaded. But I don't want to lose the Microsoft Office that she had installed previously. Help?

I recently bought a pre-loved Macbook which has been sparsely used but I only realised Mackeeper was installed after I got back home. I did a thorough check previously before I bought it but I didnt know what Mackeeper was until I checked it out online. I want to get rid of it completely and the only way to do that is to reset my Macbk to factory mode but by doing so, I will delete Microsoft Office too and the previous owner had lost the key product no and the neccessities to reinstall the software. I have seen others say something about moving it to an external hard drive but I don't have one and I think it would be costly? Please, any experts on this matter come forward and give your best opinions. Thanks!
Additional info -
Software type: OS X 10.9.2

The first thing to do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. You — not the previous owner — must do that. How you do 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.
1a. If you don't own another Mac
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 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.
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. For early MBA models, you may need a USB optical drive or Remote Disc. You should have received the media from the previous owner, but if you didn't, 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.
1b. 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 create a bootable USB device and boot 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 boot 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.
2. Partition and install OS X
If you see a lock screen when trying to boot 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 authorized service provider to be unlocked. You may be asked for proof of ownership.
Launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In thePartition 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.
After partitioning, quit Disk Utility and run the OS X Installer. You will need the Apple ID and password that you used to upgrade. 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.
Then 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 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.
3. Other issues
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, Mac App Store 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 to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information.

I want to sell my MacBook Pro-How do I find the exact model number?

It's late 2011 i7 15 inch and the specs I pull up show 2.4GHz MacBook Pro (MD322LL/A)
Except that i'ts when I click About this Mac it shows:
Processor 2.5 GHz Intel Core i7
Memory 4 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 384 MB
Serial Number C0**********W47
Software OS X 10.9.1 (13B42)
It also gives this info:
Processor and memory
2.2GHz or 2.4GHz quad-core Intel Core i7 processor with 6MB shared L3 cache; or optional 2.5GHz quad-core Intel Core i7 processor with 8MB shared L3 cache and I know it's this and 750 GB SATA Disk
4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 memory; two SO-DIMM slots support up to 8GB
Basically, I'm wanting to sell it because I just don't need such an expensive Mac and I hardly ever use it. I bought it new in September 2012 and it's in mint condition. Since it was a model year behind, I only paid $1899.
I have the box but I'm out of town so I was just hoping to figure out what I want to do. I still have the original receipt, it has Office University (or whatever it's called) and a Magic Mouse.
Any ideas of where/how I should sell it? I usually use Craig's list but I don't think that's a great idea for this item. Also, how much do you Apple experts think I should ask? I'm addicted to my iPad 2 but it's on iOS 5 still because it's, well, you know...I like to configure my displays and icons and be able to free memory,etc. so I mainly use it. Thanks for any help! Much appreciated!

Carrie,
the information that is provided by About This Mac is accurate. What you have is a CTO (“Configure To Order”) variant of the MD322LL/A; thus, referring to it simply as a “MD322LL/A” does not uniquely identify it. I would recommend describing it as a “2.5 GHz 15-inch Late 2011 MacBook Pro with 4 GB of RAM and 750 GB HDD”, so that the buyer knows exactly what you’re offering. Make sure that the box, the other original accessories that came in the box, and the original receipt are included with the MacBook Pro; picky buyers (like me ) appreciate receiving all of those constituent components.
Note, however, that according to the Mavericks software license agreement, that because its installed version of Mavericks was originally downloaded from the Mac App Store, its copy of Mavericks is non-transferable; you will need to erase Mavericks and its recovery partition from the MacBook Pro’s internal disk before selling it. It would save the buyer some time if you would also perform an OS X Internet Recovery to restore its original Lion onto its internal disk before the sale.
To get an idea of what you should ask for it, take a look at online auction sites to see what other 15-inch Late 2011 MacBook Pros are selling for. You are likely to find more 2.2 GHz and 2.4 GHz models than 2.5 GHz models like yours, so you could add a premium of some amount to whatever the more common models are going for. If you live in an urban area, Craigslist could be used to sell it, as long as you and the buyer can agree on acceptable payment terms; finding a willing buyer might be more difficult if you live in a rural area.

thank you.

A Mid 2010 MacBook Pro supports 16 GB of memory without any problem. Macs are "special" about memory because some brands work without any problem and others don't work. That's why I recommend you to buy the memory from OWC or Crucial in order to make sure that you get compatible memory > http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3

I want to change my macbook hard drive to a bigger drive

I want to change my macbook hard drive to a bigger drive, its a duo core. I would like to know what make is best and where do i get the tools for it eg screwdriver, static protector . Where do I order my drive from.
Can I change my drive on this model. I'm in the uk. thanks for the help

These are very good instructions on How to Upgrade Your MacBook's Hard Drive.
Here is the Apple DIY hard drive replacement instructions.
The only step they left out is the need for a number 8 Torx Driver to swap a shield from the old drive to the new.
Tools can be ordered on the net or check with some friends you never know what they might have. The hardest one to find will be the Torx driver but some radio shacks carry them.
OWC carries an assotment of nice drives. Check the bottom of the page in the link below.

This will give you an idea of what you need.
Here is a place in the UK you can check.

I want to upgrade my macbook pro mid 2010's ram

I want to upgrade my macbook pro's ram to 8gb's I don't want to spend $200 on ram from apple, i Know that with buying it from apple, if it doesnt work they will do it for you, and it guranteed to work, i just don't have the money to do that.
they outlined how to do it here http://support.apple.com/kb/HT1270#link1
and i found some memmory here
http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=2F9CE069A5CA7304
I am confident in my computer knowledge that I can install ram in a mac, i've done it to dozens of pc's
so what i'm looking for is reassurance before I do anything thank you

There should no problem in installing 8 GB RAM in your MBP. Crucial is one of the best sources of RAM for Macs. Now if you are so inclined, you can install 16 GB from OWC, the other reliable source for Mac RAM.

Mountain Lion.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
MacBook Air (Late 2008 or newer) model number 2,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported.
Application Compatibility
You can also check which applications are PowerPC by going to the  menu, select About this Mac, click on More info…, then click System Report and select Software/Applications.
If you have applications that you want to use that aren’t compatible, you can retain Snow Leopard and create a new partition to install Mountain Lion on or you can run Snow Leopard server in a virtual mode.

I want to upgrade my MacBook late 2009 Ram, any suggestions?

Hi, I've been wanting to upgrade my MacBook's RAM for a while now and I wanted to make sure what brand I should buy. I searched this up on amazon.com: PC2-6400 DDR2 800 MHz Type RAM. I then found this: Crucial 4GB Kit (2GBx2) DDR2 800MHz (PC2-6400) CL6 SODIMM 200-Pin Notebook
Memory Modules CT2KIT25664AC800. Is this the right kind of RAM I should Buy?

OWC is excellent, DataMem, and Crucial. Links go directly to ram for your mac. You can upgrade to as high as 8gb.

What All Do I Need If I Want To Upgrade My Macbook Hard Drive?

any comments are welcome.
thanks!

I got a 320GB sata 2.5" hard drive and installed it myself, its easy. I also got a caddy so I can use my old 120GB drive as a back up. Make sure u have everything backed up! Seagate and western digital drives are most popular. I asked similar q and got this answer"
Extended Hard Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
If your backup is bootable, then boot from the external drive and use SuperDuper to clone it back to the newly installed drive.
Mac Pro 2.66 Ghz; MacBook Pro C2D 2.33 Ghz; MacBook Pro 2.16 Ghz Mac OS X (10.5.4) Intel iMac C2D 17 "; MacBook 2.0 Ghz.

Welcome to Apple Support Communities
The Mid 2011 Mac mini supports 8 GB of memory officially, but you can install up to 16 GB of RAM, so you can use 2, 4 and 8 GB modules. You can buy more RAM from OWC or Crucial.
If you are looking for memory at a local shop, make sure you buy 1333 MHz DDR3 memory. See > http://support.apple.com/kb/HT4432?viewlocale=en_US&locale=en_US
