Unfortunately I can't provide Mac OS specific instructions because I'm using Windows so hopefully someone else can help with that. Here's a general overview: To compile avr_boot you need to...

@JadinAndrews that's great news, thanks! As soon as I get some time I'll do some testing with all the boards I have on hand as well as a test build...

I did more testing of avr_boot on ATmega2560: | Programmer(firmware) | 6.0.1/DA | 6.0.1/DB | 6.3.0/DA | 6.3.0/DB | | --- | --- | --- | --- | --- |...

By "Pin 14", do you mean the Arduino pin number (as you would use with `digitalWrite()`, etc.) or do you mean physical pin 14 on the ATmega328P chip? If the...

OK. That's the information I needed. avr_boot doesn't use Arduino pin numbers to define the CS pin. It uses the PORT/BIT number. So the first thing is to determine the...

Thanks @anatom74! I'm caught up in other projects right now but I am definitely planning to try to resolve some issues and make some improvements to avr_boot at some point...

>i am unable to select standard pinout as it will not compile, By default the ATmega1284P standard variant requires Mighty 1284P to be installed: https://github.com/JChristensen/mighty-1284p/tree/v1.6.3 That is the cause of...

>Im wondering if this could be a fuse setting or lock bit? The correct fuses should be set when you do Tools > Burn Bootloader. I did fairly comprehensive testing...

We'll continue the conversation here: http://forum.arduino.cc/index.php?topic=534935 and then come back to GitHub if it turns out the problem is caused by a bug.
