I had a lot of problems like this
on mac intel (10.4.
1. arduino0006 caused system crash (block & grey screen) & errors (programmer not responding, )
2. arduino 0005 worked fine
on mac ppc (10.4.7)
1. arduino0006 caused crash
2. arduino0005 did not start
3. arduino0004 worked fine
I'd istalled the latest drivers in the 0006 package
I'd run the macosx_setupcommand
now I just changed 1.4+ to 1.5+ in the info.plist and the order in the java preferences panel
and the latest version seems to work fine, possible?
