How to repair your MacBook Pro with an Apple-branded firmware update
Mac users should upgrade to a firmware update from Apple after a software update from another vendor, according to a new Mac update guide.
While the Mac OS X update process is pretty straightforward, it’s actually quite a bit more complicated than just installing the firmware update.
Here’s how to get an update from your local Apple affiliate and then update your MacBookPro to the latest firmware.1.
Connect your Mac to a network that supports DHCP and verify that your Mac has an internet connection.2.
Open a terminal window and navigate to a folder that contains the following files: mac-firmware-update-update.plist macfirmkey.plists mackeychain.plies macos-install-factory-macosx.pl macs-mac-install.pl 3.
Copy and paste the following text into the terminal window:mac-update/mac-keychain-update_3.1_1_Mac_update_5.3_1.pl.pl The text is pretty self-explanatory, but it contains a bunch of information.
Once you’re done copying and pasting, save the file and then double-click it to open it.4.
If you’re using the Mac version of the Mac Software Update app, you can download and install the update from the Apple Store.
You should have the update automatically installed, though.5.
Once the Mac software update is installed, open the update folder.6.
Double-click the update file you just copied and it should start downloading the update files from Apple.7.
Once it’s downloaded, you should see an error message in the MacOS update log.
The update is complete.
If not, make sure that you don’t have the MacSoftwareUpdate app running.
If the Macsoftwareupdate.app is still running, you’ll need to restart the computer.8.
Now, you may be able to download the update manually from the Mac App Store, but if the update is still not downloaded, then it may not work as intended.
To fix that, open up the MacApp Store, then click on the Updates tab and scroll to the bottom.
Scroll down to find Mac SoftwareUpdate and click on Update Now.
You will see a window that says “Downloading…” then scroll to “No” to proceed.
Once that happens, your Mac will automatically download the firmware from Apple and install it.
You should have updated to the newest firmware version when you restart your computer, though you may need to reboot to see that the update has taken effect.9.
If all goes well, you will now have an update installed.
The next step is to reinstall Mac Software Updates on your Mac.
The process is fairly straightforward.1) Open a Terminal window and then navigate to the folder that has the following file: mbus.pliskets.pliktm.plos mbuses-mac.pls mbu.plisks.plis mbusers-macboot.plios 2.
Copy the following contents of the MBus.PLINKTETS.PLIKTM.PLOS folder into the Terminal window:3.
In the Terminal, type the following command to reinstalling MBus: sudo dpkg -i MBusPLINKETS.plinktm.PLoS 3.
Repeat the same process for MBusBUKTERS.PLIS.MBUS 4.
Now you can go back to the MacInstallFactory.plim and restart your Mac, and you should be back to a clean, updated firmware version.
