"not on the approved list of Dashboard Widgets"

Hi,

Does anybody knows what is causing this message to pop up? It only happens on on my son's account which was setup by the school. And it only happens if we try to install a new widget on this account. But on other similar accounts it worked fine.

Tks..

 

The mac was purchased from school and they are the one who installed the OS including the account used by my son. I believe what they did was just copy from a clone.

But I have the admin account and even activated the root account so I can pretty much do anything I want with the system. But what I can't figure out is what so special about this account that they created. I have created another account and set it up as managed and this account can install and run the widget with no restriction.

 

That's what I thought at first. But the other account that I created has the same restrictions. Actually, both account, even though managed, are not restricted by the 'Parental Control':

System:

Use Simple Finder -> unchecked
Only allow selected applications -> unchecked
Can change password -> checked
Can burn CDs and DVDs -> checked
Can modify the Dock -> checked. ​

Content:

Allow unrestricted access to website -> checked.​

I actually find 'Parental Control' buggy so I switched to K9 Web Protection to control my son's access to the web.
