Hello everyone, I have a friend that has a small size company and he was asking me about switching completely from Windows to Mac, which better place to ask other than here. I got exited when he asked and I started talking about how good it will be, and now I'm wondering if it Mac can in fact make a difference, and can it be better. He wants to be able to Share folders and give different folders access to different users, what does Mac have as Active Directory? he would also like some users to have Remote Access to desktops (iMacs) He wants to remotely backup files to clouds, I'm sure there are tons of services out there. Does Mac Server come with a firewall built in? what would one use for Anti-Virus? thanks guys, I hope my friend can jump over to full Mac. Let me know if I'm missing information. He is thinking of getting Mac OS Server and iMac clients.
