[QUOTE="sago48, post: 1508686, member: 209649"] Hi there. Thanks for the link. See below for the procedure I used. My screen did scramble but a reboot fixed that. I can't say I understand exactly what this does, but it seems to work. BTW do I need another mac to do a flash drive installation and a target boot to install Lion on my mini? Currently Lion says it can't install. "1) Download Archive.zip: [url]http://www.mediafire.com/?lfangrn69rxln3q[/url] 2) Extract Archive.zip and place the two files in "/System/Library/CoreServices/Firmware Updates" - You'll be prompted for a password to authenticate 3) Using Terminal, execute this command: Code: sudo bless -mount / -firmware /System/Library/CoreServices/Firmware\ Updates/EFIUpdaterApp.efi -payload /System/Library/CoreServices/Firmware\ Updates/LOCKED_MM11_0055_08B.fd -options "-x efi-apple-payload0-data" --verbose - Again, you'll need to enter a password to execute the sudo - You'll get a screen of information, as it blesses/mounts the firmware updates. 4) Shut down your Mac Mini, and hold the power button down until the front light begins to flash. 5) It should begin the firmware upgrade process then reboot. Give it time to complete." Good luck. [/QUOTE]
