ehhhhmmm... I don't get your point Astronerd.
Shutting down the OS before disconnecting the power prevents corrupted file systems and thus boot problems. Please correct me when I'm wrong.
I shut it down by clicking "shutdown" and waiting a minute or two. If you want to know exactly how long it takes to shut down, connect a monitor to see how long it takes.
No i meant that what he said was correct to use the shutdown icon...I was agreeing with the guy...sorry as you posted Inbetween and I think it confused things.... I was a bit slow...
Looks like I'm in the same boat as you. Where do you download the new update? I'm assuming I'm going to have to reinstall on the SD card? Is this something I can download from the StellarMate.com website? Can I do this on a MacBook Pro with Mojave or another OS? This is the screen I am stuck at and it's non-responsive.
