ASCII Table not uploading - verification error content mismatch

  • I'm an absolute beginner and just installing the rokit smart inventor V2 for the first time. I've downloaded the Arduino IDE, installed the add on files, downloaded the driver, set the board and the port (and almost each step needed troubleshooting). Now when I upload the ASCII Table, it gives me the following:

    Arduino: 1.8.13 (Mac OS X), Board: "Rokit-SmartInventor-mega32_v2"

    Sketch uses 3194 bytes (9%) of program storage space. Maximum is 32336 bytes.
    Global variables use 273 bytes of dynamic memory.
    avrdude: verification error, first mismatch at byte 0x002e
    0x15 != 0x11
    avrdude: verification error; content mismatch
    avrdude: verification error; content mismatch

    Please help–I'm trying to get started!

    @granazi Hi there,

    We apologize for the delay. Unfortunately Arduino has some trouble with some versions of the Mac OS, especially Catalina. Please upgrade your computer to the latest version of Mac OS X if possible. Unfortunately, the Arduino issue is out of our control. You may need to keep checking on Arduino and Mac updates to see if the issue gets resolved.
