How to use nohup on os/x

The command

nohup <command> &

does not actually work properly on mac it seems: the process is suspended. Issuing

fg

appears to be required to reactivate the command.

Here is an illustration:

$nohup jekyll serve --watch &
[1] 47426
$appending output to nohup.out


[1]+  Stopped                 nohup jekyll serve --watch

Now, on Linux the process would not have been "stopped" by issuing that command..

So .. what is the way to achieve this on mac?
