Re: Serious problem
Hi, Neil, The simple constraint is that the only items showing on the monitor are the Apple and the progress bar — absolutely nothing to click or see. At least, it is rigorously protecting the computer. I just now have written to Daniel. Again, thanks — WAMUG rocks!

Re: Serious problem
Hi Pat, OK maybe I hadn’t explained the hardware test/diagnostics properly - the Apple and the progress bar should not come into it. The first step is to switch the computer completely OFF – preferably using the power button or, if all else fails, by turning off at the power socket. Then, following the instructions on the relevant Apple support articles, the hardware test/diagnostics is invoked BEFORE the computer can get to the Apple and the progress bar stage. However, I guess I am probably more comfortable with all this – so I quite understand that you may be more comfortable just leaving it to an expert like Daniel. Cheers Neil -- Neil R.

Yesterday a message came up on the computer that the firmware for the tablet needed to be updated because in the new Mojave update Apple neglected to classify Wacom as safe software, and it was necessary for users to modify items in the Security Preferences panel. So I read the instructions and followed them (I thought). Unfortunately, I think I omitted a step and then tried boot the computer. The result was that the monitor now shows only the white Apple and the stalled progress bar. I did a Safe boot, but it didn’t work.

Re: Serious problem
Hi, Neil, I have now tried the diagnostics test as you suggested, but sadly, that also had no effect. (My ‘puter is a late 2013 Mac Pro.) I do appreciate your time and effort to help, and I thank you very much.
