I’ve been using Microchip’s MPLAB X on Mac OS X for some time now, and really getting along nicely with it.
I use it for various projects and with a range of different hardware targets and programmers.
I’m using MPLAB X v1.90 with PicKIT2, PicKIT3 and ICD3 and until recently I’ve had little or no trouble.
Last week, however, I allowed the 2013-005 Java Software Update from Apple to install. This updated my VM from JRE 6 to JRE7 (aka Java version 1.7).
Everything seemed fine until I tried to program a device using my ICD3 debugger/programmer.
