Installing 8GB ram on MacBook Pro (Mid 2010)

Hi, I have bought 8GB(2*4GB) ram to install on my macbook pro, when I install both I get a black screen but when installing one or the other with one of the original ram they both work. What can I do to fix this problem??

When you install RAM, reboot your computer with the "D" key held down (or the Option-D keys). These will load the Apple Hardware Tests.
With these tests open, check the box for the extended memory test, and then start the test. This will have the system thoroughly test the RAM for errors.
In your case, it appears you may have a bad set of RAM modules, but you can check them using the method above.
When you have them paired with your original RAM, how much memory does the system report as being available when you select About This Mac in the Apple menu? If you are using Lion or Mountain Lion, then in this panel click "More Info" and then select the "Memory" section, and see what the system reports as being installed.
Is this RAM test necessay with every upgrade of memory or just if you have problems after the upgrade
Thanks

Installing Windows 7 on MacBook Pro mid-2010 13" with Mavericks?

Hello, my 13" macbook pro mid-2010 is only capable of running BootCamp 4, but has Mavericks which can only run BootCamp 5. Is there any way to get around this to install Windows 7 through Bootcamp or any ways to downgrade from Mavericks to Mountain Lion without a Time Machine backup? I also know that virtual machines and Parallels are out there, but I need a separate partition for Windows for gaming.
Thanks.

I just got off the phone with Apple Support. They have decided to make MacBook Pro mid 2010 models non-compatible with BootCamp 5. They have also decided to make OS Mavericks only compatible with BootCamp 5. Therefore it will not work at all unless you downgrade your OS. It is not possible to use BootCamp on mid 2010 MB Pros with Mavericks.

Installed 8GB Ram into Macbook Pro, System Report says it only has 2GB RAM

I decided to upgrade my 13.3 inch MacBook Pro from 4GB Ram to 8GB Ram.
I purchased two Crucial 4GB Ram from two different dealers on Amazon and installed them myself.
I turned my MacBook on and now it says that only one slot is being used and that it is a 2GB.
I have a feeling that either one of the Ram slots has failed, however it still puzzles me that it says that 2GB of RAM is installed? Is there any way of refreshing the 'About This Mac' or is there anything to make the Mac recogise this problem?
Thanks in advance

open the mac back up and make sure both ram modules are seated properly. It takes a little hard push to get them seated and you will hear a click/snap when they are seated. To determine if a ram slot has failed, simply put back in the old ram, and if both slots are recognized, the problem is with the new ram.

Can't install mavericks on my MacBook Pro mid 2010. Can't detect the HDD.

Hi all, find it very frustrating trying to install the new OS after the hard drive is not detected. I'm trying a clean install of the Mavericks using an 8Gb usb flash drive.
However, when trying to reformat the drive using disk utility and trying to repair to drive to see it there is a problem I was able to do both without any difficulty.
Here's the steps I've undertook so far.
1.) Boot the MBP using the Mavericks installer downloaded in Apps store. I have created beforehand the USB installer using Lion DiskMaker app. I have tried the installer working on my wife MacBook Pro 2011.
2.) Pressing alt key during boot up will only show my USB stick without the formatted HDD. Selecting the USB stick will show a circle with a line and shuts down the MBP.
Any valuable help is much appreciated.

Welcome to Apple Support Communities
At first, it looks like your Mac is not compatible with OS X Mavericks, so maybe you were using a different OS X version like Lion.
To check whether your Mac is compatible or not, open  > About this Mac > More Info, and check "Model Identifier". It should be "MacBook5,1" or higher (if you have got a MacBook) or "MacBookPro3,1" or higher (if you have got a MacBook Pro)

I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.

I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.
From what I read, I have 2 choices: 1. to install OSX and then upgrade to Mavericks, but I'm not sure if this would be possible (to upgrade directly from OSX to Mavericks); and 2. to use a software called Super Duper.
I wouldn't like to have to use a third party software to do this, so the question is: is there a better way to install directly the Mavericks not having to use a third party software?

Install the new drive in the computer.
Install the old drive in an external USB or Firewire enclosure.
Boot the computer from the Recovery HD on the external drive.
Use Disk Utility to partition and format the new internal drive.
Clone your external drive to the internal drive.
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 Recovery HD on 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 Recovery HD then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility from the main menu and click on the Continue button.
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. Using Disk Utility still opened.
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.

2. My concerns/questions
     For quite some time now, I've been planning to upgrade the memory (RAM) of my MacBook Pro from 4.00GB (Apple Stock) to 8.00GB. In terms of "FASTER BOOT TIMES, IMPROVED RESPONSIVENESS (OPENING and CLOSING PROGRAMS, FILES & ETC.), SMOOTHER GRAPHICS, ABILITY TO OPEN MORE PROGRAMS SIMULTANEOUSLY AND OVERALL IMPROVEMENT IN PERFORMANCE", does it really make a BIG difference?
     If ever I am going to pursue this upgrade, should I let Apple do the upgrade or buy the parts and do it myself?
     If I am going to buy the parts and install it myself, what brand do you recommend? Crucial, Kingston, OWC & etc.?
     Why does Apple charge so much for memory (RAM) upgrades? Is the memory module they are using any special compared to the ones we can find in Amazon (Crucial, Kingston, OWC & etc.)?
Thanks for helping me out with my concerns.

I recommend OWC RAM because it's reasonably priced and OWC's support is great if you ever need it. I recommend installing the RAM yourself because it's dead simple. There is no good reason for anyone ever to pay Apple's prices for RAM.
I don't think you will see faster boot times with more RAM, but that shouldn't be a concern, because there's seldom any need to shut down or restart a MBP. Just put it to sleep when you aren't using it, unless you won't use it again for more than two or three days. Opening and closing programs won't benefit significantly from more RAM either, but when running multiple large programs at once, you will see a significant improvement in their performance. It's well worth the small investment ($65) to upgrade from 4GB to 8GB.

Unable to open Bootcamp install of Vista after upgrading MacBook Pro / Mid 2010 to OS Mavericks

Dear Community,
I am unable able to boot the Windows Vista install (via Boot Camp) on my MacBook Pro / mid 2010 after upgrading to OS Maverick.
Any idea about how this problem can be solved (I don't want to purchase Windows 7 and I don't want to purchase a virtual machine)?
Many thanks for your support!

My MacBook Pro mid 2010 was upgraded to mountain lion os x and then my wifi started saying no hardware installed

My MacBook Pro mid 2010 was upgraded to mountain lion os x and then my wifi started saying no hardware installed

Hello Harrisonhcue,
I would be concerned too if I was getting the message "no hardware installed" when trying to use Wi-Fi on my MacBook Pro. For a message like this, I recommend resetting your System Management Controller (SMC) and NVRAM.
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
You can find the full article here:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/ht3964
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Just installed Mountain Lion Latest Version on MacBook Pro Mid 2010

I want to make sure, that after i spend so much money on a high end mac book pro in December of 2010, that now i can't even use the feature of apple tv mirror because my lap top has to be early 2011 or later. Please confirm Apple Gurus so that i can be sure that im didn't do anything wrong. I have the latest Apple Tv but my MacBook Pro 17 was purchased in dec. 2010. which makes it a macbook pro mid 2010. If the case is i can't utilize the mirror for my desktop to show in apple tv, then why does it work with itunes and every other device? so weird, plus i need to make sure i've done all the troubleshooting possible so then i go ahead to the next step and buy the USB to HDMI Cable that way i can do it the old way since my mac book pro high end is now considered old. So dissapointed.

Look at this link. It indicates that a third party application will allow you to use it:

Macbook Pro Mid 2010 (Model 6.2) restarts like cray cray

Can't believe this is happening...
Macbook Pro Mid 2010 Model - Intel i5 2.4GHz - RAM 8GB - GPU NVIDIA GeForce GT 330M
So I've seen quite a lot of threads discussing the 'GPU Panic' issue since I first encountered it a few weeks ago. The problem had never occurred on my MBP prior to that. However, the situation is now so bad that I wouldn't be able to open the Mac OS and make a copy of the panic report before it automatically reboots. Fortunately I have Windows 8 installed on the machine so I am still able to post for help on here.
A few questions / personal thoughts on the issue:
I bought this MBP back in June 2010 in China... So I won't be eligible for a free repair by any means right? It's been almost fours years since the purchase - significantly longer than three years restricted by Apple. I've seen another user who posted how they successfully defended their consumer rights by bringing some printouts of consumer laws and regulations. Lots of respect for that... But surely that only applies to goods purchased in the UK right? I'm so screwed... If a repair costs a few hundred quid then there is no point doing it, is there? I guess I can live with Windows for one or two years before the machine wears out and then get a new one. That being said, I still wonder if anyone in similar situation has managed to get free repair (GPU / logic board replacement or whatever it is). If so, mind sharing your story?
Is it nearly impossible to make a Genius Bar reservation nowadays or is it just me? My plan was to bring my MBP and talk to a genius and see where it goes. But both Covent Garden and Regent Street seem fully booked until a distant future. The reservation page does not show any available time slots, it simply says 'There are no available appointments at this store'. I mean I don't really mind if it is in a few days, a week, a month or even a year, just give me something. Telling people 'no availabe appointments at this store' is not very helpful is it? Since I have never had a Genius reservation (never had any issue using my MBP until this one - the good old days are gone) before, I'm curious what would happen if I just walk in with my MBP. Would they ask me to make a reservation or would they serve me right away?
Since I have never encountered the GPU panic issue (or any issue really) before I upgraded to Mavericks 10.9.2. I had never had any similar problems running Windows (Previously Vista, 7 and now 8) on my MBP either. I am speculating maybe the GPU Panic issue is more of a software bug. I am not ruling out the possibility of the GPUs being defective, but considering that fact everything was perfectly fine before the arrival of the evil Mavericks (for me, the upgrade to Mvericks 10.9.2), maybe the specific problem is down to Mavericks? I think this could be good news because Apple could quickly fix it for everyone as long as they know about the issue. Well... I don't think our chances of getting it sorted quickly are good, especially not when the new iPhone/iOS, which generates 10X more profits than Macs, is at the most critical stage of development. What do you guys think?
Oh it is just so frustrating. Using Windows on a Mac is definitely a nightmare - miserable 2 hour battery life and noisy non-stop fan spinning. Someone please help....................

In the Replacement Program Support Article, it states:
Apple will service affected 15-inch MacBook Pro computers free of charge until three years from date of purchase. This worldwide Apple program does not extend the standard warranty coverage of the affected MacBook Pro.
http://support.apple.com/kb/TS4088
According to these terms, you are outside the eligibility window. However, I still second andyBall_uk's sentiments.
Make a Genius Bar Reservation. Print out a copy of the kernel panic report and the Support Article. If the 'Genius' refuses servicing without cost, ask for the store manager. It is ultimately at the manager's discretion.
Additionally, if this doesn't work out, you can look into Apple's flat fee repair program:
Do You Know About Apple's Flat Rate Repair Pricing?
Best of luck.

MacBook Pro Mid-2010 kernel panic at each restart

Hi,
As most of you, I succumbed to temptation to update my MacBook Pro (mid-2010) with OSX Lion. First, I've done a traditional upgrade from Snow Leopard (10.6.8) from the Mac App Store. Due to some problems (see list bellow), I've decided to make a clean install (by extracting the file InstallESD.dmg from the Lion downloaded package. I've burned the package on on 16GB USB key (8GB is sufficient). Well.. On both type of installation I've encoutered the same problems.
The 99% of the time, my MBP make a kernel panic at the start (both when I do a simple restart of the system or after restating the system after a normal shutdown.
As I use mainly my MBP for professional use, I set the system to ask for a user logon at system start. Mainly each time, it wasn't possible to logon to the system. As soon as I tried to enter my password, I only see the game wheel icon turning on the screen and no possibility to enter my password. In this state, my only solution was to restart my system by pressing the power button.
Both of these two problem was replicable in either an upgraded system or on a clean install.
Finally (because I'm a patient guy :-) ), I've do a third clean installation, restored my system from one TimeMachine backup and found a solution to avoid having the problem I explain into the point 2.
When you restore a backup from TimeMachine from within Mac OSx, you have to create a second admin account, log onto this account and run the Migration Assistant to restore your backup. Admitting that, like me, during the clean OS installation, you've used the same account name as the one you had into your backuped installation, at the time of the TimeMachine restore, Migration Assistant will propose you two things:
Create a new user and restore our TimeMachine backup on this new username
Replace the existing username on your clean installed machine my the one that was backup into timemachine
As I've previously created a new account with admin right, I've logged on this account, launch Migration Assistant, confirm that I'm okay to restore my TimeMachine backup on the already existing user.
Finally, this setup resolved my point 2 problem. The difference between my initial setup and the one I use now is that I've now two users presented on my logging screen. To log on now, I've to choose the user, enter the password and never had the problem I had before with only one user set on my system.
Now, I really hope that Apple will fix this first version of Lion asap. For the rest, I'm pretty happy with the system. I'll work this week with Lion and will see if I encounter other problems. One thing is sure, I'll keep my TimeMachine backup of my previous Snow Leopard system at a safe place until I'll be sure that Lion will be stable.
Cheers....

Hi,
That's correct, I'm running with one RAM chip, after testing the bays work correctly first, I elliminated that route, so it was indeed a bad RAM chip module.
I was just about to give up, as the first swap was with the good RAM out, so same problem. I thought I had nothing to lose by swapping the RAM again, and voila, it worked. I'm opening up some seriously big photoshop files at present, just to make doubly sure it's been resolved ha ha.
I'm looking at replacing my RAM now with OWC, as apparently according to their website and with the correct EFI updates, you can max out the mid 2010 MBP with 16GB of RAM. I'll much rather treat myself to that, than forking out on a new logic board.
I think it's quite a simple, but effective fix this one.
Thanks for all the advice and help, I really did appreciate it.
Ciao,
Adrian

BootCamp 5.0 error on 13" MacBook Pro Mid-2010: "Installation Error. Boot Camp x64 is unsupported on this computer model"

Installing Boot Camp 5.0.5033 (downloadable at http://support.apple.com/kb/DL1638) on Windows 8 x64 on 13” MacBook Pro Mid-2010 using BootCamp\setup.exe, I get the following message: “Installation Error. Boot Camp x64 is unsupported on this computer model”.
According to http://support.apple.com/kb/HT5634, Windows 8 x64 is not supported by Boot Camp 5 on 13” MacBook Pro Mid-2010 .
Previous version, Boot Camp 4.0, causes bluescreens on Windows 8 (https://discussions.apple.com/message/20131524#20131524).
Fortunately, it might be still possible to employ updated Boot Camp by launching “msiexec /i BootCamp.msi” from BootCamp\Drivers\Apple folder using administrative command prompt (http://technet.microsoft.com/en-us/library/cc947813%28v=WS.10%29.aspx).
However, new Boot Camp 5.0.5033 does not contain all the drivers for 13” MacBook Pro Mid-2010. E.g. driver for NVIDIA nForce System Management Controller (labeled Other devices/Coprocessor in Control Panel) and NVIDIA nForce PCI Systems Management (labeled Other devices/SM Bus Controller in Control Panel) must be obtained at Drivers\NVidia\NVidiaChipset64 in older Boot Camp 4.0 (downloadable at http://support.apple.com/kb/DL1634)
According to Microsoft (http://windows.microsoft.com/en-US/windows-8/system-requirements), the MacBook Pro config (Intel Core 2 Duo P8600 2.4GHz, 4GB RAM) exceeds Windows 8 x64 hardware requirements. Windows Experience Index for this laptop is approx. 5.1 (http://windows.microsoft.com/en-US/windows-8/what-windows-experience-index).
Does anybody know, is there any technical reason why Windows 8 x64 is not supported by Boot Camp 5 on 13” MBP Mid-2010?
Is there a specific hardware/firmware deficiency in this MacBook model, incompatible with Win8? Maybe NVIDIA refused to provide Win8-compatible drivers for its chipset components (GeForce 320M graphics card though is still supported by latest notebook drivers available at www.geforce.com)?

Thanks for the detailed explanation! If MacBook supports AHCI/SATA only in native “UEFI mode”, while reverting back to PATA/IDE in legacy “BIOS mode”, then it could make perfect sense to use UEFI to make sure that technology like Native Command Queuing (NCQ) is employed, as it may give noticeable performance improvements for certain operations: www.happysysadm.com/2012/12/intel-g530-nas-performance-part-3.html. I wonder how do you get Windows 8 x64 with EFI bootloader installed on MacBook?
Simply choosing EFI Boot (“Some EFI platforms support both UEFI and BIOS firmware. On some of those systems, it is not always clear if the default DVD boot option is an EFI or BIOS boot option. On these systems, using the EFI shell command may be required. If you do not specifically start Windows Setup by using the EFI boot entry, the default firmware boot entry for BIOS may be used. If Windows Setup starts in BIOS mode on a combined EFI/BIOS system, the ESP and MSR partitions are not created.”) from Win8 x64 DVD when installing on blank HDD would yield “The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed" message. Also, if the hard drive was not in SATA mode during Windows installation, registry tweaking may be required before switching from PATA to SATA. Do you do registry tweaking and EFI bootloader configuration manually after a copy of Windows was installed in its dedicated partition in a regular way?
