Latest Macos For Macbook Pro Early 2011

  

For example, for Mac OS X 10.7 Lion, released in mid-2011, Apple notes that an “Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor” is required, but not which models; 2GB of RAM is. There were many model A1181 White MacBooks. If the machine can boot, boot it up and then click on the Apple menu at the top left and select 'about this Mac'. Provide us with that information. But based on the A1181 model number, the maximum version of OS X it can run would be Lion (10.7.X).

To identify your MacBook Pro model, use the information in How to identify MacBook Pro models.

Removing or installing memory

Warning: The internal components of your MacBook Pro can be warm. If you have been using your MacBook Pro, wait ten minutes after shutting down the computer to let the internal components cool before continuing.

Step 1: Remove the bottom case

  1. Shut down your MacBook Pro. Disconnect the power adapter, Ethernet cable, USB cables, security lock, and any other cables connected to the MacBook Pro to prevent damaging the computer.
  2. Turn over your MacBook Pro and remove the ten (10) screws that secure the bottom case. Because the screws are different lengths, note the screw lengths and locations so you can replace the screws correctly. Put them aside in a safe place. Lift off the case and place it to the side.
  3. Touch a metal surface inside the computer to discharge any static electricity from your body.

Step 2: Remove existing memory (if present)

  1. Push the levers on the sides of the memory module in an outward direction to release the module from the memory card slot. The memory pops up at an angle. Before removing it, make sure you find the half-circle notches. If you don’t, try pressing the levers outward again.
  2. Hold the memory module by its notches and remove it from the slot.
  3. Remove the other memory module.
    Important: Hold the memory modules by their edges, and do not touch the gold connectors.

Step 3: Install memory

  1. Align the notch on the gold edge of the module with the notch in the lower memory slot.
  2. Tilt the card and push the memory into the slot.
  3. Use two fingers with firm, even pressure to push down on the memory module. There should be a click when you insert the memory correctly.
  4. Repeat this procedure to install an additional memory module in the top slot. Press down on the module to make sure it is level.
    Note: Make sure you install the memory according to this illustration, with the gold contacts inserted almost completely into the connector.

Checking that your computer recognizes the new memory

After installing additional memory, you should confirm that the computer recognizes the new memory. To check the computer’s memory:

  1. Start up your computer.
  2. When you see the Mac OS X desktop, choose the Apple () menu from the upper-left menu bar, then choose About This Mac.

The total memory includes the amount of memory that originally came with the computer plus the new memory you added, or if all the memory has been replaced, the new total for that memory. For detailed information about the amount of memory installed in your computer, open System Profiler by choosing Apple () and then About This Mac. Then, click More Info and then Memory from the Hardware section that appears in System Profiler.

If your computer doesn’t recognize the memory or doesn’t start up correctly, confirm that the memory you installed is compatible with your MacBook Pro and that it is installed correctly by reseating the memory.

How do you upgrade the RAM in the 'Mid-2009' through 'Mid-2012' MacBook Pro models? What type of RAM do they use? How much RAM does each model actually support?

Please note that this Q&A is up-to-date and covers pre-Retina 'Unibody' MacBook Pro models. EveryMac.com also provides details about RAM options for the subsequently introduced Retina Display MacBook Pro line.

The RAM upgrade procedure for the 'Mid-2009,' 'Mid-2010,' 'Early 2011,' 'Late 2011' and non-Retina Display 'Mid-2012' MacBook Pro models is fairly easy. It's not quite as easy as it is for earlier 'pre-Unibody' MacBook Pro systems, as these later models require a screwdriver, but it still is simple and straightforward.

Identification Help

Latest Macos For Macbook Pro (13-inch Early 2011)

If you're not sure which MacBook Pro you have, these models can be identified by the Model Identifier 'closely enough' to an exact match for the purpose of upgrading the RAM. In turn, each model can be uniquely identified via model identifier and one or more secondary identifiers (like processor speed and/or processor type).

EveryMac.com's Ultimate Mac Lookup feature -- as well as the EveryMac app -- also can uniquely identify these models by the Serial Number, which is listed on the bottom of the notebook in small type toward the hinge, as well as within the operating system alongside the model identifier. More details about specific identifiers are provided in EveryMac.com's extensive Mac Identification section.

To locate the model identifier in software, select 'About This Mac' under the Apple Menu on your computer and click the 'More Info...' button. If the MacBook Pro is running OS X 10.7 'Lion' or later, you will need to click the 'System Report' button after clicking 'More Info...' as well. EveryMac.com has carefully hand documented each model identifier for your convenience.

The model identifiers for each of these models follow:

RAM Types & Actual Maximum RAM Capacities

All of these systems have two memory slots that are accessible by removing the bottom case, but the type of RAM as well as the actual maximum capacity varies for different models. Apple formally recommends that you 'fill both memory slots and install an identical memory module in each slot' for all of these systems.

The 'Mid-2009' and 'Mid-2010' MacBook Pro models support 1066 MHz PC3-8500 DDR3 SO-DIMMs and officially and unofficially support a maximum of 8 GB of RAM with one odd exception.

Specifically, as discovered by OWC, the 13-Inch 'Mid-2010' MacBook Pro models (and only the 13-Inch models) -- the MacBook Pro 'Core 2 Duo' 2.4 13' Mid-2010 and 'Core 2 Duo' 2.66 13' Mid-2010 identified by MacBookPro7,1 -- can support up to 16 GB of RAM with dual 8 GB memory modules if they are running OS X 10.7.5 or higher, have been updated to use the latest EFI, and are equipped with proper specification memory modules. If running a version of Mac OS X 10.6 'Snow Leopard,' these models only can use 8 GB of RAM.

Latest Macos For Macbook Pro Early 2011 Latest Os

The 'Early 2011' and 'Late 2011' MacBook Pro models use faster 1333 MHz PC3-10600 DDR3 SO-DIMMs. They officially support 8 GB of RAM, but OWC has determined that they actually support 16 GB of RAM regardless of the operating system installed, although only the 'Early 2011' MacBook Pro models are capable of running a version of Mac OS X 10.6 'Snow Leopard.'

Finally, the 'Mid-2012' non-Retina Display MacBook Pro models use faster still 1600 MHz PC3-12800 DDR3 SO-DIMMs and likewise officially support 8 GB of RAM, but actually can support as much as 16 GB of RAM. These models do not run versions of OS X prior to OS X 10.7 'Lion.'

RAM Upgrade Instructions

Apple explains how to install memory starting on page 35 of the 13-Inch, 15-Inch, and 17-Inch 'Mid-2009', 13-Inch, 15-Inch, and 17-Inch 'Mid-2010,' and 13-Inch, 15-Inch and 17-Inch 'Early 2011' MacBook Pro User Guides, respectively, and this provides most of what you need to know to upgrade the pre-installed memory.

The 'Late 2011' MacBook Pro models are so similar to the 'Early 2011' models that Apple didn't bother to release an updated instruction manual. For the 'Mid-2012' MacBook Pro line, Apple's 'Quickstart' Guide does not cover RAM installation, but the procedure is the same as earlier models.
