I have two Arduino Megas which I have been using fairly regularly. I updated my operating system to OSX 10.10.1 yosemite, and I can no longer program these arduinos. They simply do not appear under the ports menu, and I have no way of connecting to them. Does anyone have any ideas on what the problem may be, and/or what I can do?
(My computer is an Early 2011 Macbook Pro)
I've been trying to solve this for a while, and this is what I've learned:
-My Arduino Uno R3 will still show up under the ports menu.
-The Arduino Megas do not show up using Processing nor under the USB Prober application meaning that it's not just the Arduino IDE.
-I've tried versions 0022, 1.0.1, and 1.5.8
-I have an Ardupilot Mega (APM) autopilot which is based around the ATMega2560 chip. It is not recognized by my computer either.
-Apple made some changes to the FTDI drivers in Mavericks and Yosemite.
-Weirdly, the megas were working for about a month on yosemite before they disappeared from my ports menu.
-I've tried this:
-I've tried using the dmesg command but I don't really know if it worked.
-I've tried to follow this tutorial but did not know what to do by step 5.
