I have an old IMac and I'm the only user. Apparently I'm not an administrator however and am having problems downloading a new program. How can I check whether or not I'm really not an administrator and if not, how can I can settings to allow my to modify my computer?
Open System Preferences > Users and Groups. Under Current User it should indicate your username and beneath that it should say "Admin." If there is only 1 user account it should be an admin account; if it isn't an admin account there is a problem.
Before going further, exactly what model iMac do you have and what version of macOS is running on it?
