Memory(RAM) upgrade on a Mid-2012 MacBook Pro

Hello Apple fans and users. My Mid-2012 MacBook Pro 13" is a bit slow. It has 2x2GB DDR3 1600MHz Ram and when I open more than 4-5 tabs in Safari it becomes really really slow. So that's what's bothering me and I have decided that I need to upgrade my RAM to more GB's. I have iStat app and it shows me that more 3/4ths of the RAM is being used when I have more than 4-5 tabs open in Safari and when my iTunes is playing a song.
So Im from the Netherlands and what I found is this:  http://www.alternate.nl/Corsair/4-GB-DDR3-1333/html/product/922656?tk=7&lk=9331
It even says MAC Memory. I find this good because it is supposed to be for a MAC, but my only concern is that my memory right now is 2x2GB 1600MHz, and the one that Im currently looking at(at the link) is only 1333MHz.
Do you guys think this might be a problem or it is bad or is it going to be a NOT SO GOOD upgrade? Im not very good with computers but from what I know 1333MHz is less than 1600MHz...
But I also found this -> http://www.alternate.nl/Kingston-ValueRAM/4GB-ECC-DDR3-1600/html/product/1118143 ?event=search
and it is 1600MHz, DDR3, 4GB BUT I AM NOT Sure if it's gonna work on my laptop because it is a MAC.
So what do you guys think? Which one should I get and why? Is there a difference between 1333MHz and 1600MHz? And what is it? How am I gonna feel the difference?

As BobRz says, get the right speed, or you may have problems.

  • Occasional restarts on mid 2012 macbook pro after ram install?

    Hi,
    Recently installed 2x4gb Corsair Vengeance DDR3 memory to my mid 2012 Macbook Pro 13" to upgrade the ram to 8GB.
    Since then i have been having almost daily forced restarts, where it says it has to restart because of a problem, i believe it
    is a kernel problem.
    Also have been experiencing many repeated "Aw Snap" messages on Google Chrome although this could be unrelated.
    The specifications for my mac are:
    OSX Mavericks 10.9.2
    Processor: 2.5 GHz Intel Core i5
    Memory: 8 GB 1600 MHz DDR3
    Graphics:  Intel HD Graphics 4000 1024 MB
    Has anyone had any problem with this type of memory? I believed it would work when i bought it.
    Original memory was 4GB that came installed in the Macbook Pro.
    Other than occasional restarts, everything seems to work fine other than "aw snap" messages on latest version
    of chrome (have tried disabling extensions, making a new user profile, reinstalling Chrome, none of which has worked).
    Would appreciate any help, advise etc. Will be reinstalling original memory, see if the problem persist.
    Cheers
    Tom

    The RAM must be stated by the manufacturer to be compatible with a mid-2012 MacBook Pro.
    Just because it says:
    1600 MHz PC3-12800 DDR3L SDRAM SO-DIMMs (204-pin)
    Does not mean it is compatible.  It must say mid-2012 MacBook Pro RAM.

  • After upgrade to Mavericks, AppleTV no longer mirrors my mid-2012 Macbook Pro's accessibility zooming.

    Prior to Mavericks upgrade, I had accessibilty zooming enabled using the control hotkey with two-finger scroll.
    The zoom effect would be duplicated in AppleTV and transmitted to an overhead projector in my classroom.
    This feature is very useful for directing student's attention to a particular region of the screen.
    However after the upgrade, AppleTV no longer mirrors the zooming effect.
    I can see the zoom on the laptop, just not on my projector.
    I can see zooming on the projector if I use the VGA adapter and plug directly into projector.
    Laptop:
    mid-2012 Macbook Pro
    OS X 10.9
    8gb RAM
    2.3 GHz Intel Core i7
    Have tried variety of displays settings and none work including:
    --selecting best for display or AppleTV
    --changing the resolution
    AppleTV
    model: MD199LL/A
    software: 6.0 (6646.65)
    resolution: 1024x768 60hz (my projector requires this)
    Projector:
    HP vp6320
    I use an HDMI to VGA/Audio adapter to convert to VGA for my projector.
    I seem to recall that overscan correction was an option to set under Mountain Lion, but I can't find that when doing a Spotlight search in System Preferences. Not sure if that would help or not but thought I'd mention it.
    Any help would be greatly appreciated.

    Same problem. Zoomed image will not show on the Apple TV screen even though it does show on your laptop or desktop.
    I tried every aspect of System Preferences>Displays and Accessibility. None worked. Problem was presented to an Apple Specialist on his Mavericks computers and his Apple TV. Same thing. He said this appears to be a Mavericks glich and immediately went to transmit the problem to Cupertino.
    A poor "work around" is to use System Preferences>Accessibility and under Zoom, select Zoom Style "Picture-inPicture" which will result in a "zoom box." The box can be scaled to a desired size and activated with the Control-Scroll motion. This box will display zoomed on the Apple TV screen. The default Zoom Style selection "Fullscreen" did not and will not show on the Apple TV screen even though it does show on your laptop or desktop
    The problem: the zoomed "magnified" image loses resolution and if zoomed far enough, becomes "pixilated."
     Apple needs to fix this or tell us how to go back to the earlier Control-Zoom which I think the "Fullscreen" was intended.

  • Yosemite Upgrade on mid 2012 Macbook Pro

    How does the Yosemite upgrade perform on Yosemite upgrade performance mid 2012 Macbook Pro with 2.5Ghz i5 processor and 16GB RAM?

    I haven't had any problems on several upgrades. You should do this in advance as a precaution:
    Repair the Hard Drive and Permissions - Yosemite, Mavericks, Mountain Lion or Lion
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
    Repair
    When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list.  Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility 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 Disk Utility and return to the main menu. Select Restart from the Apple menu.

  • Installing RAM, Mid-2012 Macbook Pro?

    Can a user or owner install RAM, Mid-2012 Macbook Pro?
    Is it a straightforward process? I've installed RAM into DT macs..and into a "Pismo" era powerbook.
    thank you

    "is a Spudger absolutely necessary to remove that plug,"
    Battery plug? No you can just  use your fingernails. I actually use a #3 Master Airscrew nylon propellor from the hobby shop, cut in half and wrapped w/ self fusing electrical tape. I have about 6 of them and half are pretty worn out.
    "are there any screws or other parts which might wish to fly out and away as a person opens the case and gets at this task?"
    No it's just the way the bottom fits on to the MBP. You fit it in the back (near the vent) first, then pull it forward and into place.
    The other thing is the screws are different lengths in the bottom so just keep track of where they belong. If you don't force anything you won't get into trouble because it's fairly obvious if you have the wrong screw in the wrong place. If you're doing a super pro job you would add a tiny dot of blue "Thread Loc" to the tip of the screw when you put it back.

  • Can anyone give a list of upgradeable performance parts for a mid 2012 macbook pro 13"?

  • Mid 2012 macbook pro glitching, freezing, overheating

    Starting a few weeks ago, I noticed a change in my mid 2012 macbook pro. My laptop was losing charge EXTREMELY quickly, I would charge the laptop to 100%, and just an hour later (after not using it, but the lid closed and it was sleeping) it would be up to 60% charge, then when not in sleep and on, it would lose energy extremely quickly. I always make sure that unecessary background apps are not running--so that was not the problem. This problem went away after a week, but it was the first signal that something was wrong with my laptop.
    Next, the laptop was having problems with waking up from sleep, I did an SMC reset and this problem was fixed.
    After that, the laptop started glitching (static and banded lines on the bottom of the screen) and making this clicking noise when I was streaming video fullscreen on Netflix. I thought at first, that this was a problem with Silverlight, and reinstalled the silverlight plugin (several times). Then I noticed that the computer would glitch when I was streaming full screen on Netflix and picked up the laptop (moved it from a flat surface). This signaled to me that the problem was perhaps not software, but a hardware issue. I verified the disk and did a permissions report and neither were curative.
    Further support that the problems are with hardware rather than hardware came to me when my computer presented itself with a fourth issue: the laptop, when being lifted or moved from a static surface, would sometimes freeze entirely and make the same clicking noise. This problem was not during fullscreen streaming, but had spread to when I was simply using more than one app at the same time (e.g. having Chrome and Word open together). When this happenend, the only solution would be to power down the computer and restart.
    Finally, while sleeping with the lid closed in my backpack, I hear a whirring noise--I pick up the laptop and it was hot to the touch, overheating with the fans running on high speed.
    I have no clue what is going on. I have taken the computer to my university's mac shop and they have suggested it is a logic board issue and I should give the computer in. I have scoured the forum for an answer of what is happening and am determined to find one. So I pose the problem to you--any help would be appreciated. Thank you.

  • Mid 2012 MacBook Pro 13 restarts when moved

    Hi everyone,
    I have a mid-2012 MacBook Pro 13 inch that still has the factory 8gb ram and 750gb HD and the 2.9 i7. Recently i have been having issues with it restarting, the first couple of times it did it would only do it when i would move it and right before it would restart the screen would glitch a little. A little bit after that it would restart if i was running something memory intensive like converting movie files. And finally at one point it wouldnt boot up at all and would beep 3 times, after that i opened it and just swapped the the 4gb ram and it worked just fine. I also clean installed Yosemite right after that and it was fine for about a week and now its starting to restart whenever i move it again. Before everyone tells me to buy new ram or take it the genius bar I want to know if theres anything else i can do, Im in college right now and I'm not covered by applecare anymore so my budget it very limited so i would like to make those a last resort kinda thing. Thanks for your time!

    An appointment at an Apple genius bar is FREE.  If repairs are needed, you will be told of the costs and you can accept or reject any repair quotes.
    Based on your description, it indicates that there is a loose connection.  I would open the MBP and inspect to see if it can be located.
    You might also run an Apple Hardware Test:

    An error free AHT is not definitive.

  • 15" Mid 2012 MacBook Pro Crashes Every Few Weeks! Crash Report Attached.

    Hello everyone. My 15" Mid 2012 MacBook Pro has been crashing every few weeks... Initially I thought it was due to Hands Off! (an app i used to limit outgoing/incoming connections) so I uninstalled it. However my macbook still crashes every now and then.
    Specs of my MacBook Pro:
    Processor  2.6 GHz Intel Core i7
    Memory  16 GB 1600 MHz DDR3
    Graphics  NVIDIA GeForce GT 650M 1024 MB
    Software  OS X 10.9.5 (13F34)
    Below is the crash report if someone can tell me and explain what the issue is, that would be great!
    Thanks

    There are a couple of things you should look at.
    Macs are very selective when it comes to RAM.  Install the original RAM and see if there is any change.
    Second, look at these items:
    One or more of them may be the source of your issues.
    Ciao.

  • Will this 2x8gb RAM work on my 15" 2012 Macbook Pro?

    Will this 2x8gb RAM work on my 15" 2012 Macbook Pro?
    Also if this is not the best, can you suggest a better option? thanks

    You run the risk of owning perfectly good memory that does not happen to work in your Mac.
    The best way to shop is to patronize Vendors who promise:
    "It works in your Mac,
    Or your money Back."
    These guys do and usually have pretty good prices as well:

    I would like to put an SSD in my Mid-2012 MacBook Pro. As the tradition HDD is a real bottle neck the system. Space is not really an issue, but price is at the moment. It's between these two, Crucial M4 128GB VS Samsung 840 120GB, just to be used for everyday use, thoughts?

    I'm a huge Crucial fan - I have a 512GB Crucial m4 SSD series installed right now and am eagerly awaiting the shipment of the Crucial M500 960GB SSD. One thing that I love about Crucial is that you can accomplish firmware updates directly on your Mac - with Samsung, I believe, you have to use a Windows machine.
    Crucial SSDs are perfect for Macs - many of us around here have them.
    The only problem that I see that you may run into is getting the data from your hard drive (you don't say how much space you're using on it) to a 128GB SSD. If you're under 128GB on your HD then you can just clone your data and OS, etc., onto the new SSD. Or you can make a 'fresh' start and format the drive and install the OS and then begin the laborious task of adding your apps back.
    See my one and only user tip - Upgrading your MacBook Pro with a Solid State Drive - for some tips on transferring that data. I've always used Carbon Copy Cloner - but then I've always been moving to a SSD that was comparable in space to my 'old' HD.

  • Can I capture video through a mini display port on a Mid 2012 MacBook Pro?

    I want to run my xbox through a mini displayport adapter into my Mid 2012 MacBook pro to record gameplay. I understand that at one point the 27" iMac's supoorted this feature to an extent. I'm open to other options for inputs, ie: composite cables from the xbox or even VGA. I own a capture card already I'm just interested to see if there is a way around using it to save space and the mess of extra cables.

  • How to connect mid 2012 MacBook Pro to home theater system

    Okay so I'm looking at purchasing a home theater system and was wanting to know the best way to connect my mid 2012 MacBook Pro to the home theater system and TV. I am wanting to play both movies (Netflix etc) and music. Will my MacBook play 5.1 surround sound to the home theater system? Whats the best way to connect this all up? MacBook audio to the home theater system via Digital Optical from the headphone port with a 3.5mm to toslink adapter and then video to the TV via HDMI cable from the thunderbolt port with thunderbolt to HDMI adapter? My thinking was to separate the video and audio to get the best picture and sound. Any help/advice on this would be greatly appreciated.

    Will my MacBook play 5.1 surround sound to the home theater system?
    Yes.
    Whats the best way to connect this all up?
    An AppleTV or any AirPlay-enabled AVR. AirPlay is wireless, though you could use wired Ethernet if you want to avoid all the potential problems associated with wireless. Make sure it specifically says AirPlay which is Apple's proprietary technology. There are quite a few of them to choose from today. Denon is one, I believe Pioneer, there may be others. Shop around. The AppleTV's price was recently reduced to $69 US and may actually be the most cost-effective solution, allowing you to research the best AVR for your needs. The AppleTV has both HDMI (audio and video) and optical audio outputs.
    MacBook audio to the home theater system via Digital Optical from the headphone port with a 3.5mm to toslink adapter and then video to the TV via HDMI cable from the thunderbolt port with thunderbolt to HDMI adapter?
    Way too complicated But if you really don't want to use AirPlay, you can purchase an inexpensive (< $10) Thunderbolt to HDMI adapter and an equally inexpensive (<$3) HDMI cable to any HDMI input on your AVR.
    My thinking was to separate the video and audio to get the best picture and sound.
    It makes absolutely no difference. HDMI and optical audio use completely identical digital audio signals.

  • Please help me find an effective solution for an external optical drive for my Mid 2012 Macbook Pro.

    I have replaced my optical drive with a DataDoubler and they both work fine but the new external optical drive enclosure doesn't work with the optical drive I took out of my Mid 2012 Macbook Pro... Well it does work and recognises my optical drive perfectly, it runs fine but it can't handle some disk installations.
    I have heard that the apple external superdrive isn't reliable for playing DVD's or lasting either. 
    Can I have someone with experience with external optical drives to give me professional advice or just other people with solutions.
    Below is an image of what I have now for an enclosure.
