    Boot into Safe Mode and see if you have the same issues. Try safe mode if your Mac doesn't finish starting up - Apple Support

     

    If not, figure out what third-party system modifications you have installed and remove them.

    This program can help you see what you have installed: http://etrecheck.com/

    Note the time of the next freeze. After rebooting open the Console app in Finder>Applications>Utilities and look for log entries at the time of the freeze. Post suspicious ones here.

    Look before the log entry that starts with BOOT_TIME since that is the first line of a bootup

    If it doesn't freeze, then it is either third-party software that loads at startup, or a hardware component that is disabled in Safe Mode.

    If you don't have any guesses as to what software it might be, this program will show you what you have installed: http://etrecheck.com

    No sorry, went slowly when I was in Safe mode. The log is in normal mode.

    But What it is this that "Service exited with abnormal code: 255"?

    It is what the process returned when it exited. Normally, a process will return 0 indicating no errors.

    You'd have to look at the OpenSSH web page for what that exit code means, if they have published it.
