    I'm getting a new macbook
    usually I just use time machine
    but does it modify the OS?

    I have mavericks but I think macs now have the newer OSX pre installed?
    I will probably just use the newest OSX
    are there any reasons to reinstall programs one by one?
    I usually do this on PC

    You won't be able to restore your TM backup if your TM is on Mavericks. Latest Macs can only support the latest OS, it's written in the firmware that you can't install or even boot from an earlier OS.

    Either use Migration Assistant to copy specific apps/files, or update to El Cap and backup again - then you can restore directly to your new machine.

    That's basically you're only choice. The oldest version of OS X you can rollback too is the version it came with. There are at times some exceptions to that rule.

    Personally, I like this option and while its more time consuming it gives me a new machine exactly, how I want it. For instance, on my old MBP, I have 2 versions of Photoshop, 3 versions of Lightroom. My new iMac, I only have the latest flavors of both.

    Using Migration Assistant maybe easier to get your data and apps over but I prefer the specific control of what I want installed.
