    Teensyduino v1.28 OS X installer "damaged"

    Downloaded Teensyduino v1.28 today and got an error that Teensyduino.app was damaged and could no be opened. D/L'd again with no help (same checksum.) I notice that the v1.27 installer is 111MB whereas the v1.28 installer is 97MB. This on OS X El Capitan v10.11.4 (latest version as of this date.)

    See attached screenshot of error.

    MD5sum of my download:
    ~ $ openssl dgst -md5 < installed/teensyduino-v1.28.dmg
    99abc53b68f99b860e5d385d75381e4e
    ~ $

    Thanks for your help.

    Can you try running this command in a Terminal window (in the directory with the application, probably /Volumes/Teensyduino)

    Code:
    codesign -d -vvvv teensyduino.app/
    Hopefully this will give some more info about why it's broken.

    All that info looks correct. The MD5 matches my copy here. I'm afraid I just do not know why it's failing.

    Doh! On a whim I rebooted my machine and after that the v1.28 installer completed just fine. I have no idea what the reboot cleared up, but all's well now.
