It could look different, sure, but until they add every identical command and even something basic as the new ribbon feature which I can't live without now, then avoid. Your best option is running AutoCAD on Windows through Parallels. I want the same behemoth of a program, this is a very poor offering. Which is nice, except it comes at the cost of a complete butchering of an industry standard program. I read that they wanted to give Mac users a "unique Mac-like experience". Literally there's basic commands on Windows that have no Mac counterpart.
It's very backwards that I spend all day at work using the program one way then come home to use the same program except now I have to use different commands and options that are placed in different places. How can you make an industry standard program and leave features, commands & options out? I was excited to finally get a native Mac version and let me tell you, it's disappointing. I posted this under 2012 LT, but it still applies.
