    Forgive the question, but google wasn't helping.

    I'm new to Mac, and I'm wondering how much of my 256gb SSD will be taken up by the OS and core applications (like Safari/Garageband/iMovie/Mail etc). Any guesses/advice?

    I've ordered a 13" MBP with touchbar, 8GB memory - if that makes a difference.

    I have the 256GB. I keep most stuff on a NAS.

    I believe the OS is around 80GB. I have 30GB of apps. 20GB of movies (I move them to and from local storage as I need to). With other miscellaneous files kicking around, dropbox sync etc., I have around 115GB free.

    iTunes (80GB) - NAS.
    Photo Library (Lightroom - 220GB)) distributed locally and on the NAS, but 95% on the NAS.

    After formating you end up with 232GB, OS X and its apps will likely eat a good 30GB. However, you also loose towards the recovery partitions and root partition space.
