I'd recommend HxD.ģ) Download this file, containing the clean ME region for the MacBook Pro 8,1.Ĥ) Next, open both it, and your dumped ROM in a hex editor.ĥ) In the ME region file, highlight everything by pressing Ctrl + A keys, or right-clicking, and selecting 'Select All'. Save the dump in a safe location, and make sure to make a backup copy in case something goes wrong!Ģ) Open your dump in a Hex editor.

All EEPROM programmer software is different). A computer running Windows - For your EEPROM programmer (most have Windows-Only software), and hex editing.ġ) First, dump your system's SPI-ROM using your EEPROM programmer (you're on your own for this. An SMD rework station - To desolder the SPI-ROM if necessary for your programmer. Perhaps it isn't suited to program the chip while in circuit. However, there are some clip-on adapters that you can use, but I've never had much luck with the one I got. This kind of adapter requires desoldering the SPI-ROM and placing it into the adapter, you CANNOT use it to program the chip without removing it from the logic board. An EEPROM programmer - I use a MiniPro TL866, with an SOP8 adapter. I wouldn't recommend doing this unless you have at least a little bit of experience. The system kept on using Intel HD Graphics 3000.īefore I go into detail, just a warning: Performing this process requires an EEPROM programmer, and possibly desoldering the system's SPI ROM. The machine WOULD NOT switch to the dedicated graphics card NO MATTER WHAT I DID!!! Unchecking 'Automatic Graphics Switching' in the Energy Saver PrefPane did nothing, and GFXCardStatus did nothing either, even when forcing dedicated graphics. After installing my newly-flashed EEPROM with MBP 8,1 ME region onto the logic board and booting, the machine worked just fine.

When I accidentally did this to a corrupt SPI-ROM I was trying to recover from a failed firmware update, I did just this - Not realizing that the ME regions differed between the MBP 8,1 and 8,2/8,3. I just thought I'd start this thread to announce a recent accidental discovery I made today - a (possibly) PERMANENT solution to disable the dedicated video card in a 2011 15' or 17' MacBook Pro!Įssentially, what needs to be done is the ME (Management Engine) region of your system's SPI ROM needs to be replaced with a clean one designed for a MacBook Pro 8,1 (a 13' 2011 MacBook Pro - Which doesn't have a dedicated graphics card).
