every time i turn my mac on, on the logon screen, instead of my profile picture, it appears a question mark, and when i hit the hint button, it says that the user graphic resources seems to be invalid. and i am the only user of my computer and i have alredy turned off the guest user, but i still remains there, as an "only safari enabled guest account". what do i do to fix the profile picture and the graphic resources problem? and how do i disable the "only safari enabled guest account"?
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
