I even managed to find time to upgrade to Mountain Lion in the summer. I dutifully followed the directions and had no troubles with my USB adapter. the USB adapter out while my terminal program (ZTerm) was still open. The mountain lion (Puma concolor) is also known as the cougar, puma, panther, and catamount, and is the largest wildcat in North America. Mountain lions have. ZTerm - Macintosh Modem Communications ZTerm is a terminal emulation program for the Macintosh. universal binary, works on Lion Under OS X, ZTerm. I'm looking for a ZTERM replacement. Anything out there? Seems this area is notably empty in the Mac arena only thing I've really found was. It hasn't been updated in years but still works great in Mountain Lion. which driver I installed on my machine but it works well with ZTerm. ZTerm is a horrible Mac OS X app. It hasn't been updated in five years or so, and isn't a Universal Binary. The developer doesn't seem in any.
