i am trying to program my MM manually because i have a MAC computer and can't use castle connect... ESC off, transmitter on, hold full throttle, turn on ESC... 4 tones, blinking green light, but no 2nd 4 tones to enter programming mode...

i need to make sure that I am in lipo mode because the esc does not do the beeps between on and armed tones that are supposed to tell me how many cells are detected, so i am a bit worried about my lipos

MM came with a truck i bought... i guess i could send it in, but it seems to work just fine, i just want to try tuning it

Either call Castle support and see if you're doing something wrong or there is something wrong with the MM. I've always used the Castle link or the Field Link, never tried manual programing, quit doing that with Quarks.

The newer way to program Castle ESCs, the 'Field Link' doesn't use a PC and you can set the cutoff voltage, auto lipo cutoff volts, drag brake. brake strength, punch control, reverse type, motor type and motor timing and CHEAT mode.

It can also be used with a PC providing all the Castle Link capabilities.

well, i ended up having to borrow a PC laptop... restored default settings, and now things are up and running much better, and lipo cutoff is working flawlessly
