Indeed, all it took was a mini power surge. Our commercial power was interrupted. It takes about 10 to 15 seconds for our home generator to come on line.From what I could discern the iMac was in the process of updating it's OS which it usually does automatically, (That process is now on manual mode), and the short delay between the generator coming on line and commercial power dropping was enough to crash the upgrade process. I have a 4 TB external hard drive connected to the iMac, its sole purpose is to act as mirror drive to the iMacs internal SST drive. So no data or files were lost and I could restore everything from the backup drive. Apple devices have the ability to share everything between devices such as iPhones, iMacs, iPads and Mac Pros, that neat ability caused all the extra recovery time today. What I create on one device shows on the others. Having spent years working in the Microsoft World and having Android phones I thought that was a neat feature
. I switched from my
I loved it "Blackberry" to an iPhone when my provider no longer supported 2G
. I've restructured my setup now so my iPhone shares photos only with my Mac and iPad.
Sorry for the long tale, but I learned a good lesson today.
