"To reset the firmware password on newer Macs, you must now follow these steps: It is described here and is part of the apple firmware unlock procedure The long reset code that you haven't heard of is not related to iCloud, AppleID, or anything other than a firmware password. I've read firmware password was moved to some amtel chip starting late 2011.Ĭlick to expand.Thanks for your continued assistance. I've seen some guides on chip replacement to bypass unkown firmware passwords, but only for similar models, not this exact one. SMC version 1.70f6.Īny ideas? I have a ch341a bios programmer and I'm willing to tinker and risk bricking if it makes sense. My bootrom is 87.0.0.0.0, which I believe is the latest and not downgradeable. I've also upgraded the firmware of my SSD and ran a secure erase from a linux live CD. I've since tried everything from high sierra also with no progress. If I boot into MacOS and run firmwarepassd from terminal, it also appears I have no firmware password set. If I set one, it has no effect after I restart (old password still required if booting with option held, or if I attempt to reset nvram I prompted for firmware password and kicked into recovery). When I go to startup security, it claims I have no firmware password set. I then downgraded to Lion (original OS for my laptop) to attempt to remove the password. I was able to boot once after a couple of tries, but never again after I tried to run the OpenCore post-install patcher despite attempting to reinstall from scratch.ĭuring diagnostics I tried to remove the firmware password- Monterey's recovery was incompatible with with my firmware so no luck there. Recently I tried to abandon that and upgrade to Monterey using OpenCore Legacy.
Since then I progressed through the supported versions of MacOS (ending at high sierra), and eventually tried out Catalina with Dosdude1's hack. I also installed an aftermarket SSD and replaced the optical drive with the original spinny drive. Somewhere around the purchase time I set a firmware password that I still know.
I am the original owner of a 2011 17" macbook pro. After a few days of searching I haven't been able to find anyone else with this issue, maybe someone here can point me in the right direction.
