I have no application starting or loading anything when the mac starts.
I start my mac, see the login window, type my password and after that it takes a long time to login. I guess 2 to 4 minutes to login while the progress bar slowly advances.
I remember when this mac was new, 2 months ago and it would take seconds after typing the password to see the desktop and be able to operate the computer but with time, this time increased and there are days worse than others, where it takes longer.
I am proficient on terminal and other advanced stuff, if your explanation requires that.
Is there something I can do to make this faster?
