My MacBook Pro 15" 2TB arriving today will be my first non-Windows laptop. I don't know much about MacOS. I bit the bullet and went with the 2TB version because I hate - Trying to hook up external drives while on a plane or needing to carry them around at all. - Being "on the edge" with hard drive space all the time. I have approximately : 80 gb music 300 gb pictures / video 200 gb personal data 400 gb work data 100 gb other data How would you recommend I organize this data? How do you organize your data? When working with files, what will be the biggest learning curve in moving to MacOS from Windows?
