It's been awhile.  Oh so frustrating.  Have not been connected to the internet in quite awhile.  Had a brand new hard drive installed, brought all files back onto this new hard drive, then internet connection died once again, coming back on mysteriously after a week, for a glorious ten minutes.  Been on the phone with Apple Support, now 2 months after installing Mavericks, again, erasing the hard drive, (2nd time), hard ware and hard drive acting totally illogical; getting internet connection in Safety mode, but not in regular mode, then computer would not start up.  Driving Apple support tech nutz; "Truly, my team and I can figure out almost anything...had not had a case this nutty in a long time; a total erase and install should have done the trick, esp. on the second try," he said.  Took it to Apple Store today, where they checked everything out and of course my computer fired right up, took the internet connection like white on rice.  "Hard ware is great; hard drive is superb".  What??  He told me to plug in the computer and keyboard only and start adding all the other stuff while checking internet connection.  Working still.  But I'm afraid to shut it off.  So, I will do some freelance stuff, get it in and then consider turning it off.  Big shout out there for the ever so patient Scott Barnes of Apple; still miffed because internet is working and we don't know why.  Don't know if the problem is fixed; Scott does expect another call from me at some point in the future...Missed you all.  Happy Holidays~KMZ
