Mac 10.7.5
Leonardo and Uno
I was able to upload from my computer until recently. Changes since my last Arduino project that may have effect: recent update to Java, and installation of Emacs for a course I enrolled in and subsequently dropped. I removed Emacs with AppCleaner with no change.
I have tried the troubleshooting steps from the Guide. I can see my Arduino on the serial port, and it gets power and the L LED is lit. I tried a Loop-back test and, believing I did it right, it passed. (During the Loop-back test, I observed the Tx and Rx LEDs on the board lighting up every time I pressed a key, and with the Terminal screen split, I saw the letters typed appear in the second pane.)
I am able to successfully upload a sketch from another MacBook with the same OS version. I have tried rebooting and repairing permissions on my own MacBook Pro with no change. I don't know how to see what if anything is holding on to my serial port, if that is what is keeping the Arduino from responding.
With thanks in advance, can someone help me get my upload functionality back?
