I am a Mac user. I am the administrator of my macbook and set up  2 user accounts for my kids under parental control. I bought the adaptor Archer T4U and installed the driver for all users from the CD. However, the TP-Link Utility icon only shown in the taskbar under administrator account but nothing in the other 2 user accounts which are under parental control. They cannot connect to internet.

Could anyone advise? Thank you!
