> There are plenty of knockoff PICkit 3s, and in my limited sample, they > work just fine with MPLAB-X. I should buy a new one then, i have had a pk3 from sure electronics for abo= ut 6 years. At the time i updated my macbook to mavericks, it was a nightma= re to use.. i had to follow an intricate vodoo ritual every time i plugged = it and/or i had to change the firmware in but after the update to yosemite = there was no enchantement that could make the thing work.. not even inside = a virtual machine. However I can use it if i boot with the windows partition. This doesn't happen with all the pickits and the starter kits (with integra= ted pickit3) i use at work... they work with osx just fine =20 --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
