I thought I would share this (with the four or five Mac users on AOB  )  in case there are others still using OSX.3.9.  As you know, Endicia was planning on discontinuing support of the 3.0 operating system this month but because the post office isn't requiring a May postal rate increase (and resulting Endicia upgrade), they will continue support of 3.9 until January 2011.  Although this isn't "official", I spoke with Kim Taylor, ace Mac guy at Endicia yesterday and he said it is so!

He also said that down the road, (one or two years) Endicia will stop supporting OSX 4.0 to be able to gain use of some sort of 5.0 internal drivers for the Zebra printers.  So if anyone out there is doing the OS upgrades, maybe it would be wise to go directly from 3.9 to 5.0
