Macbook Pro 13 i5 2.5ghz upgrading to 16gb

Hi! I'm trying to upgrade from 4gb to 16gb on a macbook pro 13 non retina(mid 2012 version) 2.5ghz.
It says on the apple website that it will only accept 8gb but many people on the web say it can handle 16gb
Im trying with this kit of 2 x 8GB http://www.amazon.co.uk/gp/product/B008LXX9OC/ref=oh_details_o00_s01_i00?ie=UTF8 &psc=1
and in About this Mac it shows only one being used and the other space empty.
Wanted to know:
*The empty space is not being used really or even if working with 16gb it will never show?? Cause I've placed it correctly when changing the memory.
*If not being used is it better to keep with 2x4GB or 1 x 8Gb?
Thanks!!!

A 2012 MBP will accept 16 GB RAM.
About this Mac it shows only one being used and the other space empty.
Test by reversing the chips and trying then one a time in both slots. It may be that one chip is faulty. Also test the slots by installing the original RAM.
Ciao.

Macbook pro wont sleep after ram upgrade

Hi,
I have a 17" Macbook pro late 2011. I upgraded the ram from 8gb to 16gb last week and now I having trouble with sleep. When the laptop goes to sleep it always to seems to go into hibernation mode. When I open the lid I can only wake the computer by holding the power button for around 7 secs and then it does a restore from the HD. I've tried a PRAM + SMC reset. Also tested the ram and everything seems good. Below is the output from pm set, the console after hibernation restore (filtered for the word 'sleep') and the memtest. Any help would be appreciated.

Hi fatlinesofcode,
First of all, check out Apples article on the issue: OS X Yosemite: If your Mac won’t go to or stay in sleep If you find these steps don't help, try a few of the following
A common cause for the Mac not sleeping is your printer. If there are queued jobs waiting to be printed, but your printer is switched off, for some reason you Mac just wont like it and simply will not go to sleep. System Preferences > Print and Scan > Open Print Queue
Do you have an Ethernet Cable connected? People have reported in the past that removing their Ethernet allowed their Mac to sleep. This goes for other things you may have connected directly to your Mac also.
Try heading into your Mac Preferences > Sharing and deselecting 'Internet Sharing' as well as 'Printer Sharing'.
Also deselect Wake For Network Access by heading to System Preferences > Energy Saver > Power Adapter > Wake For Network Access.
Energy Saver > Schedule > Startup or Wake - Uncheck.
Alternatively, set your system preferences to Never Sleep, and put into Sleep manually: System Preferences > Energy Saver > Computer Sleep > Never.
Good luck!

Won't power up -- 17" MacBook Pro Early 2008 2.5GHz MB166LL/A MacBookPro4,1 Apple Model #A1261

I have a 17" MacBook Pro Early 2008 2.5GHz MB166LL/A MacBookPro4,1 Apple Model #A1261. I bought this used last year, and installed one of OWC's 1TB 2.5" Hybrid HD/SSD drives in it last January. No problems whatsoever until the past 2 weeks, when I started having intermittent black screens (NOT display sleep) -- sometimes the black screen would disappear by itself, sometimes I had to (Power button) shut down, and when I restarted, everything was OK. Until yesterday.
First let me note that, because I usually use the MacBook Pro in the same area in my house, I usually leave it plugged into the MagSafe power cube, and often just close the lid and put it to sleep, instead of going through start-up every time I need to access it. BTW, battery (NuPower) shows 5 solid green dots and does not seem to be a problem
Night before last, I shut down the MB Pro, and closed the lid. Yesterday, I opened up the MB Pro, and hit the power button. All I got was a brief, non-pulsing white light on the display-locking/“sleep light” button, and a sort of graunchy whisper from what sounded to me like the optical drive, NO screen activity whatsoever, and the “sleep light” went out within 3 or 4 seconds. Could hear NO HD spin-up sounds.
Tried everything I knew (not much), including disconnecting the MagSafe charger and removing the battery completely, letting it sit a few minutes, replacing battery and charger, and powering up. Same nothing, just another very brief whisper of activity from the optical drive. Being something of an “I’ll try anything, no matter how dumb it seems” idiot, I put a known, working, burned data CD-R in the optical drive. Removed the charger and battery again, waited, put everything back in. Tried to power up. Still nothing, same brief whisper from the optical drive, but the MB Pro would STILL not start up, the CD-R wouldn’t spin up OR eject, and I heard nothing from the hard drive, even with my ear ON the metal right over the drive.
My next “don’t-really-want-to-do-it” step is to remove the 1TB drive, replace it with the original 250GB drive, see if that works, and, as I have a “Newer Technology” Voyager S3 bare drive (works with both 2.5” and 3.5”) USB dock connected to my main Mac (a mid-2011 iMac, 2.7GHz Core i5, OS X 10.9.3), I’ll try using that to check the hybrid drive.
I’ve been a Mac-only user since 1989, and somehow this doesn’t seem like a drive problem. I’ve tried every OS X keyboard shortcut on the “OS X keyboard shortcuts” page, and the “sleep light” always comes on for a couple seconds, then goes out, the screen never even shows a flicker of life, and the HD NEVER spins up.
Can the forum please clue me in with any tricks I haven’t tried yet?
Thanks
Bart Brown

Thanks for the quick response. However, none of the following have worked:
Have you tried SMC and PRAM resets?
As usual, "sleep" light briefly illuminated -- 2-4 seconds -- then went out. No startup, no chime(s), no screen, no keyboard illumination, no HD spin-up.
Also try an Apple Hardware Test.
Same as above. Nada. "Mac NoteBook and Desktop computers shipping with OS X 10.7 or later have a partition on the hard drive or flash storage that contains AHT" -- since I can't get the drive to spin up, I can't access that partition... or anything else.
You may need the #2 installation disk.
Well, there I have TWO problems:
One is that I bought this MBPro on eBay, and received no disks -- it came with OS X 10.9.x installed (and is now at OS X 10.9.3). Is there any way to get “retail” install disks that will work with this MacBook Pro?
Second is that there's a data CD in the optical drive. Because the MBPro won't boot, I can't get the data CD out even if I had the 2nd Install DVD. Any way I can get this data CD out -- hatpin, barbecue skewer, fencing foil, sledgehammer?
I talked with OWC, from whom I bought the hybrid Seagate HDD/SSD 1TB drive last November. We tried a few ideas he had — mostly the same as those suggested by “Oglethorpe” (no relation to “Ogie” Oglethorpe in “Slapshot,” I hope!) — none of which worked, as I’ve already indicated above.
My last-ditch effort-of-desperation is to remove the hybrid Seagate HDD/SSD 1TB drive, and put in the original 250GB drive (never throw away a good drive!), and see if the MBPro returns from the dead. I will also put the hybrid Seagate HDD/SSD 1TB bare drive into my Newer Technologies Voyager S3 bare-drive dock, which takes 2.5” and 3.5” drives, and see if there’s a problem with the hybrid Seagate HDD/SSD 1TB drive. While no longer under warranty with OWC/MacSales, it IS still under a 2-year warranty with Seagate.
Any other suggestions gladly entertained.
Thanks again.

RAM Update to 8 or even 16GB on MacBook Pro 13-inch 2.5GHz dual-core Intel Core i5 mid 2012?

Hey folks,
i heard and read rumours, that it is possible to update the ram of the MacBook Pro 13" (mid 2012/no retina) to a double 8GB RAM, making it 16GB.
Which would be great, right?
Apple says on the support website that all the MacBooks 13" are only able to hold two 4GB making it 8.
Currently I only have the standard two times two 4GB.
So i was wondering, since I found this Crucial PC3-12800 DDR3 1600MHz 8GB SODIMM on the Internet if that's a fit for the rumours.
It says on the site:
"Guaranteed compatible with:
MacBook Pro 13-inch 2.5GHz dual-core Intel Core i5 mid 2012
Now, has any one experience with this one?
Maybe this memory will plug both slots and that's why it says compatible?
you find the website here: http://www.macdimms.com/Crucial-PC3-12800-DDR3-1600MHz-8GB-SODIMM_p_123.html
appreciate the help.

It won't plug both spots. To get 16 GB you will have to buy 2 sticks, one for each slot.
Apple only recommends and will suport 8 and recommends installing in pairs - so 2 slots of 4 GB each. You can always try the 2 slots of 8 and see if they will work. I would recommend ordering from crucial direct. They are one of the better memory companies around and have a website at crucial.com.
You shouldn't have any issues as the maximum non-Apple supported config is 16 GB.
Good luck.

I want to upgrade iMac to Snow Leopard, can I use the (DVD-Mac OS X 10.6.3) that I got with the 15" MacBook Pro that totally died, and upgrade iMac from that DVD

I want to upgrade my iMac to Snow Leopard, can I use the (DVD-Mac OS X 10.6.3) that I got with my purchase of the 15" MacBook Pro that totally died, and upgrade the iMac from that DVD that came with the laptop ? Thanks

No, that 10.6.3 DVD is system specific to the MacBook Pro.
You need a Snow Leopard Upgrade > Mac OS X 10.6 Snow Leopard - Apple Store (U.S.)

Macbook Pro 4,1 doesn't upgrade to 10.8

My Macbook Pro 4,1 doesn't upgrade to 10.8.
I tried using just the app, but also creating a separate partition with the InstallESD.dmg extracted to it, same with the BaseSystem.dmg, and some other combinations.
I have to mention, that the FireWire on my motherboard is defective, so in my current OS(10.6.8) I have the FW modules removed. I also tried several times to use an image (InstallESD and BaseSystem) with the FW modules extracted from them, but it didn't make any difference. But
When starting up in verbose mode, it hangs after the message:
"ConsiderRebuildOfPrelinkedKernel com.apple.nke.webcontentfilter triggered rebuild"
The last time, using the BaseSystem.dmg with all the packages and such copied from the InstallESD to the root of the drive, it vould hang after initializing the AppleYukon Ethernet adapter with the message:
Ethernet [AppleYukon2]: Link up on en0, 100-megabit, Full-duplex, Symetric flow-control, Debug [796d,6f08,0de1,0200,45e1,4000]
After this it would just hang for half an hour, doing nothing but reacting when I unplug and replug the ethernet cable with:
AppleYukon2 - en0 link down
And when re-plugging, same message as above:
Ethernet [AppleYukon2]: Link up on en0, 100-megabit, Full-duplex, Symetric flow-control, Debug [796d,6f08,0de1,0200,45e1,4000]
I'm slowly getting desperate, because now I'm TWO versions of the OS behind. If anyone has a suggestion that might do the trick, please be so kind... :-)
Note: During verbose boot, is says:
"FireWire (OHCI) TI ID 8025 built-in now active, GUID oo1ff3ffffe3674c6; max speed s100"
Does this mean it is loading some firewire module somewhere? And if yes, where and how can I remove it? Cause if it does, this might be the culprit...
Thanks in advance!

I am at 10.7.5 on a 2009 Macbook Pro. Why should I upgrade to Mountain Lion?

In ways, Mountain Lion is a more efficient operating system than Lion, however, if you are happy with Lion and it meets all of your needs, there is o reason to change. You can easily enough compare the features of the two and see if you are missing something that is important to you. And then decide if you want to change.

Intel Core 2 Duo is a older machine, your taking a risk with a slow machine and your presently installed PPC based software will no longer work.
Look before you leap.
http://roaringapps.com/apps:table
If a firmware update bricks your machine out of AppleCare, then your paying for the fix or a new machine.
IMMO a 3+ year old machine should remain on whatever is stable, take the risk on a newer machine.
10.7 killed my 4 year old 15", was worth $700 at the time. And Apple just basically said "too bad."

I have a 2011 macbook pro, buy yet when I connect my 16GB or 8GB Sandisk Extreme class 10 30mb card, it wont read it, however, it reads a 2GB class 2 card, is there anyway to fix this? and no, there is nothing wrong with the cards, they shoot fine, my dell inspiron 15 reads these cards fine, but yet my brand new macbook pro does not.

After many days of frustration, I try a stupid thing.... Put the SD card in the Lock Position and... Voilá!
The way I find to access the content is put the SD card in the Lock position..

MacBook Pro won't start after upgrade, not even in recovery mode

So here is what happened:
Yesterday, the app store icon told me that one update was not installed yet,because I need to restart the computer first (hard for me to reconstruct now, because I didn't really read it carefully, which I should have done, but Apple"just works™", so hey, why should I ). So I restarted the computer. This is where things went very wrong. Eventually during reboot, text appeared on the grey Apple logo screen, it looked like verbose boot mode, but overlaid on the "regular" grey boot screen with the  logo. Before I could read, what was happening, I got a kernel panic with the "hold down the power button to restart".
Holding down the power button took me to the login/file vault unlock screen (I have my disk encrypted). Unfortunately neither keyboard nor trackpad worked. So I held down the power button again, which brought me back to the login/file vault unlock screen.
At this point I noticed that it said in the lower part of the screen that, in case I had problems to enter my login information, I should press the power button for a long time and then again for a short time to get into recovery mode (this is all from my memory, I might not recall it exactly as it happened).
This made things kind of worse, it showed me the Apple logo with the progress bar, which advanced to about a third or a quarter, then the progress stopped and I ended up on a grey screen with a grey crossed circle in the center (looks kind of like an european no parking sign).
I tried booting into recovery mode by holding down the R key. This brings me to the progress bar and the subsequent grey screen.
I tried to boot into my time machine, by holding down the option key. This gets me to the boot volume selection, I can choose my time machine volume (external FW800 drive), but it does not use this volume to boot (I can hear that the external disk is not spinning). Instead I get the above mentioned behavior (progress bar, grey screen).
I tried to boot into target disk mode by holding down the T key. This only works, when I connect an external USB keyboard. This way I could use another computer to recover my important files (which is good). I could also peek at the logs. It seems as if the failed boot attempts do not produce logs. But I have the system log from the "restart to install update" process. The last few seconds or so I get a lot of these messages:
Feb 3 14:33:51 Larss-MacBook-Pro kernel[0]: Refusing new kext com.apple.kpi.libkern, v14.1: already have loaded v14.0.
I use a Macbook Pro 13" early 2011. I don't know the processor speed, because I cannot boot it. I guess it has 8 GB Ram (pretty sure I maxed it out).
I have an SSD installed (I replaced the original HD with a 1GB Samsung SSD). There is another post here, which sounds similar, but I definitely did not use "Trim enabler" or similar third party software.
I use Yosemite, I think I was pretty much up to date, I suspect the reboot was for the 10.10.2 installation, but I am not sure (I simply didn't look when I hit that reboot to install button).
Yosemite on SSD wont boot and wont go in safe or recovery mode
Anyone any ideas? Any help is appreciated!

So I just went through the install.log.
First of all, there I found out that I have a MacBook Pro (13-inch, Mid 2010):
Feb 3 14:31:12 larsmbpro.domain.com suhelperd[336]: GetModel: model = MacBookPro; major rev = 7; minor rev = 1
I think it was indeed the upgrade to Yosemite 10.10.2:
Feb 3 14:31:18 larsmbpro.domain.com softwareupdated[334]: SoftwareUpdate: Added foreground transaction [0x1] for OSXUpd10.10.2-10.10.2
but there was also a firmware update included:
Feb 3 14:31:21 larsmbpro.domain.com installd[363]: PackageKit: packages=(
"PKLeopardPackage <file:///Library/Updates/031-17157/OSXUpd10.10.2Patch.pkg>",
"PKLeopardPackage <file:///Library/Updates/031-17157/FirmwareUpdate.pkg>"
The last messages in this log are:
Feb 3 14:33:07 larsmbpro.domain.com Software Update.app[2747]: Running /sbin/reboot
Feb 3 14:33:07 larsmbpro.domain.com softwareupdated[334]: Removing client SUUpdateServiceClient pid=2747, uid=0, installAuth=YES rights=(system.install.apple-software, system.install.apple-software.standard-user, system.install.software, com.apple.SoftwareUpdate.modify-settings), transactions=1 (/System/Library/CoreServices/Software Update.app/Contents/MacOS/Software Update)
According to the system.log, the shutdown happened 14:33:08. The boot time is 14:33:24, no log entries between 14:33:08 and that time. 16 seconds seems awfully long for a reboot:
