Recovery Fails
I use an iMac, with El Capitan, Mac OS X v10.11.3,
On a-whim, I tried Recovery again. (Depressing [Command]+R at start-up.) I never get to a “desktop with an OS X menu bar & a Mac OS X Utilities window.” [Here, I quoted text from About OS X Recovery.]
I waited 1-hour, fully. [Don't worry, please: I was not sitting by my iMac that long. I went to eat lunch! :-) ] After that long, the Progress Bar looked full but-frozen. :-(
Thank goodness that I have a Power Supply Strip. All I do to shut-off my iMac's power is to flip a switch, at-hand. :-)
So Gurus of Macintosh, I ask you-all: “What do you think I should do?” Thank you, a-lot. :-)
iMac (21.5-inch Mid 2011), OS X El Capitan (10.11.3), 4 GB of RAM
