How to bypass iMac 2015 Firmware Password? first of all, I apologize for my bad english
I have a question and I will be really happy if someone can help me.
A while ago I bought an imac from 2015 as used ( so I don`t have any invoice) but lately I miss some speed and because of this I decided to upgrade HDD to SSD. When I did it and wanted to do a clean install, I got a padlock on the screen, &quot;So frimware password&quot;, and I don't have this one.
I tried to go to recovery mode via Command + R, but when I pressed that, it asks again for the password.
boot via USB failed.
NVRM reset failed
memory replacement, not helped
Does anyone have any idea about this ??
To my knowledge, you have no alternative to contacting the former owner in order to have the information or at least to recover an invoice to ask Apple to intervene.
