Hey there
What I do is setup an AWS instance under the free usage tier so a micro 2012 or 2008r2 base then use that to powershell. You use Microsoft Remote Desktop Connection for Mac. You can run a micro instance in AWS free for a year and a few $$ per month after that.
There's also a project porting powershell to Mac, I'm not sure it works for remoting but worth reading the documentation.
