How to install the firmware from a MacBook Pro "Core 2 Duo" 2.26 13" onto a MacBook "Core 2 Duo" 2.26 13" (Uni/Late 09) [Action should correct SATA speed issues and maybe RAM issues]:
1) Do a clean install of Yosemite (this should be optional, but it never hurts to start clean) 2) Download http://support.apple.com/kb/DL853 (MacBook Pro EFI Firmware Update 1.7) 3) Install Pacifist: https://www.charlessoft.com/ (or whatever software you like using to extract files) 4) Open Pacifist and then drag the MacBookProEFIUpdate.dmg into it 5) Expand: Contents of MacBookProEFIUpdate.pkg -> Contents of MacBookProEFIUpdate.pkg -> Applications -> Utilities -> MacBook Pro EFI Firmware Update.app -> Contents -> Resources 6) Drag MBP55_00AC_03B_LOCKED.scap to the Desktop 7) Click the Extract button in Pacifist and enter your password if prompted and press OK (might need to enter your password twice) 8) Quit Pacifist 9) Click Go -> Utilities 10) Open Terminal 11) Type "cd Desktop" without the quotes and press Enter/Return 12) Type "mv MBP55_00AC_03B_LOCKED.scap MB61_00C8_B02_LOCKED.scap" without the quotes and press Enter/Return 13) Make sure your laptop is hooked up to a reliable power source 14) Type "sudo bless -mount / -firmware MB61_00C8_B02_LOCKED.scap --recovery --verbose" without the quotes and press Enter/Return 15) Type your password and press Enter/Return 16) Restart your Mac (you should hear an angry beep, then see a black screen like nothing is happening for a good while, then a gray screen with a progress bar, and finally the Mac will reboot again) 17) Once your Mac has booted, open your System Report and verify the update was successful (Should show the Model Identifier as a MacBookPro5,5) 18) Have a drink! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774089 Title: Booting fails 3 times, works every fourth time after new install of Natty Narwhal amd64 on Macbook Pro To manage notifications about this bug go to: https://bugs.launchpad.net/efibootmgr/+bug/774089/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
