Unlogging other users from my older laptop MacBook computer..
How can i UNLOG two users on my older MacBook. They are "greyed" out in users , and even if i unlock the lock on the bottom, i can't seem to remove them. They have an orange check next to their name which just means that the computer thinks they are still logged in. I want to upgrade to Big Sur now that i have my computer back from my grandkids,..but it won't let me unless these two other users are UNLOGGED. THEY can't remember their passwords!! THANKS for helping out!
