Okay, I asked about this in another thread, but I feel it needs to be asked by itself. I just bought a new iMac, and after creating my accounts, I wanted to change some things, which required deleting the previous accounts. But I am not able to delete the other profiles. I go into the account preferences and unlock the padlock. However, I am unable to click on the other accounts, and the word "standard" remains grayed. I cannot change any of the details from the other accounts because I cannot even access them without signing out of my account and then signing into the others. The minus sign where it allows you to add and delete profiles remains grayed as well, but this is probably due to me being unable to click on the other accounts. I really need help with this, and responses are most welcome. Thanks.
