10.3.1-2: Some inaccuracies of the previous version fixed.
The last few days I was on a trip, so was not able to respond promptly to requests, besides, I did not want to write the answers in a hurry. But now I'm in the workplace and within three days I will try to respond to all requests, but if you do not get an answer from me at this time, please email again, the letter could have been lost. I apologize for the temporary inconvenience.
Meanwhile, David Sparks wrote an excellent review on inShort, for
which I am truly grateful to him.
By the way, I recommend his blog MacSparky, there is a lot of useful and exclusive information on the Apple products to read in it.
