Macbook Pro 2009 Latest Os



Your Mac provides several tools to help you identify it. The simplest is About This Mac, available by choosing About This Mac from the Apple menu  in the upper-left corner of your screen. The other is the System Information app. Learn how to use these tools to identify your Mac.

If you don’t have your Mac or it doesn’t start up, use one of these solutions instead:

Apple released an entry-level version of the 13-inch MacBook Pro on October 27, 2016, which was specifically targeted towards MacBook Air users. A Retina MacBook Air was released in late 2018. The 11.6-inch MacBook Air, introduced in October 2010, is only slightly larger and heavier (when closed) than the iPad 2. Apple now allows Mac users to download macOS updates for free — accessing the latest Mojave version could fix your freezing issue, provided your MacBook model is newer than 2012. Here are a few things to check before updating your MacBook Pro to the latest macOS Catalina (version 10.15).

  • Find the serial number printed on the underside of your Mac, near the regulatory markings. It’s also on the original packaging, next to a barcode label. You can then enter that serial number on the Check Coverage page to find your model.
  • The original packaging might also show an Apple part number, such as MLH12xx/A (“xx” is a variable that differs by country or region). You can match the Apple part number to one in the list below to find your model.

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.

Step 4: Replace the bottom case

Replace the bottom case. Replace and tighten the ten screws you removed earlier, making sure to put the different length screws in their proper locations.

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.

Macbook Pro Mid 2009 Latest Os Download

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.
