how to address update errors & find/load add'l apps

Looking for this kind of info via Googling or manuals mostly seems to bog me down going thru all kinds of stuff I wasn’t really looking for - yet:P … for days! Anybody have a few minutes for the quick down-low? I’ve received multiple MIME type errors on auto updates - twice - and also wondering how to browse thru additional apps that may be available for 11.1 and load them. Thanks, ‘guys’!!!

I guess nobody responded to you because your questions about errors is to generic. Try to be very specific on your questions and provide as many details as you can and most probably someone would try to help you. For the second question I don’t have an answer.
