    Is it possible? I just got brand new macbook pro retina 2014 late, it came with preinstalled yosemite. My question is can I reinstall it with maverics?

    Dont care much about backup and that soft of things.

    You should since the 2014 model is not really different then the 2013 model, so Mavericks should have the kexts (device drivers).

    You'll need to "buy" Mavericks on the MAS (it's free if you can locate it), or download it from there if already in your purchases tab. Once downloaded, follow the steps in this article to build onto an 8 GB or larger USB flash drive (new, or one that doesn't have data you care about on it).

    Once that's done, boot to the flash drive, format the internal drive in the disk utility on that drive then install the OS. Make sure you have a backup (NOT Time Machine as it may not restore a Yosemite backup to Mavericks) as you WILL lose any data on the internal drive during this process.
