I would like to upgrade my Macbook Pro Model A1278.

Question

Hi,
I would like to upgrade RAM and hard drive memory on my Macbook Pro Model A1278, but I'm not sure what is the maximum RAM I can install and what is the maximum hard drive memory I can install if its even doable. Also, which are the parts I should buy to upgrade the RAM and hard drive memory (if its doable).
Currently my macbook runs a 2.26GHz Intel Core 2 Duo processor; 3 MB shared level 2 cache, 2GB of 1066MHz DDR3 SDRAM, 160GB 5400-rpm hard drive, its a 13'' laptop, NVIDIA GeForce 9400M graphics processor with 256MB of DDR3 SDRAM shared with main memory, it currently has MAC OS X version 10.6.8.
Thanks for the help in advance!

Answer 1

Maximum Memory
8.0 GB
Memory Slots
2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM
The largest hard drive you can install is a 1.5 TB drive from Hitachi (HGST.)
You can find memory at OWC, DataMem, or Crucial.com. OWC also sells suitable hard drives, toolkits, and online tutorials.
How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
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, Leopard or Snow Leopard.) 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Step Two: Remove the old drive and install the new drive.  Place the old drive in an external USB enclosure.  You can buy one at OWC who is also a good vendor for drives.
Step Three: Boot from the external drive.  Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears.  Select the icon for the external drive then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
  1. Open Disk Utility in your Utilities folder.
  2. After DU loads select your new 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.  Otherwise, click on the
      Partition tab in the DU main window.
  3. Under the Volume Scheme heading set the number of partitions from
      the drop down menu to one. Set the format type to Mac OS Extended
      (Journaled.) Click on the Options button, set the partition scheme to
      GUID  then click on the OK button. Click on the Partition button and
      wait until the process has completed.
  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.
Step Five: Clone the old drive to the new drive
  1. Open Disk Utility from the Utilities folder.
  2. Select the destination volume from the left side list.
  3. Click on the Restore tab in the DU main window.
  4. Check the box labeled Erase destination.
  5. Select the destination volume from the left side list and drag it to the
      Destination entry field.
  6. Select the source volume from the left side list and drag it to the
      Source entry field.
  7. Double-check you got it right, then click on the Restore button.
Destination means the new internal drive. Source means the old external drive.
Step Six: Open the Startup Disk preferences and select the new internal volume.  Click on the Restart button.  You should boot from the new drive.  Eject the external drive and disconnect it from the computer.
