I am trying to update software on my macbook pro. From the apple menu, I click "check updates", software is then checked and a list presented of software that I require downloading. I then tick the relevant applications. The blue bar with "install and restart" appears, I press this, the computer goes into restart mode, I login and start all over again.
i seem to be in a loop! No authentical dialogue box appears for me to enter my name and password.
Any suggestions please!
