    Control panel 3.3.2 crashes as soon as i turn on the EPOC+. It just says program need to restart, if i restart it then happens again. If i do not turn on the epoc then i can navigate on the menu of the control pannel. Testbench works perfect. This only happens with MAC, in my windows control panel works good.
    I did not install the license files yet.

    I copy here the first lines of the error code.

    HI Heiko,

    Are you using the Emotiv USB dongle or BTLE to connect to EPOC+ ?

    USB dongle.

    I just tried in another mac with different version of OS and did not work neither.

    Cuong, I send you the full report by email.

    Hi Cuong and Aberto

    I have the same problem in my mac Yosemite. I think that this is floating point exception what can I do to solve it?

    This appears in Qt

    [I]Emotiv Engine is connected…
    QMap((0, ”))
    Floating point exception: 8[/I]

    Thank you for all your help!

    Can anyone help us with this?

    I tried again in another mac (laptop this time) and happens the same.

    The only mac we have with BTLE does not have any problem. So the problem is the connection btw dongle-mac-controlpanel.

    Now is working, thanks!

    Im still having problems, now with testbench. It doesnt save the recorded data (the problem happens only in MAC, in windows works good).

    Also, I cant change the sampling rate from 128 to 256, i tried different ways and neither windows or mac can change it.
