Admin password not accepted for updating system software
Recently I had to recover my macOS Monterey M1 machine. Therefore I needed to reinstall some things on it. For this process I created my 'new' admin account on the computer and I have been using it. I may log in and out, I may install programs, access to iCloud... but there is a specific situation in which I cannot go any further. In programs where extensions in the kernel are needed my admin password is not accepted by no means. More specifically, in System Preferences -> Security & Privacy -> General , once I click on the locker and may access (yes, there my password is accepted), when saying in the lower end "Some system software requires your attention before it can be used." and I click on "Details" it opens up a window showing a list and then I click on "Ok", then it opens up another windows saying "System Preferences is trying to authenticate user." and there my admin password is not accepted by no means -- it does not matter how many times I try.
I would certainly appreciate if anyone might suggest something I might try to solve this issue or would point me to some place where I may find a possible solution. I was even wondering whether the problem could be because of the recovery process.
I am placing this message here as a last resource since I do not really know how to proceed.
Thank you very much in advance. Greetings.
Tomás.
