    Just updated and now all my drives in my guest os, Mint 18.1 32 bit Cinnamon, are read only
    I've reinstalled Parallels tools as root and as the only user in the Guest OS and they are still read only
    Even tried opening terminal in the guest OS and running chmod and chown
    Not luck
    They resolutely stay read only regardless of how I reconfigure this VM
    Anyone got any fixes for this ?
    Its a real deal breaker for me

    Please, run ls -l commands on some file in host and guest and post output here.

    FWIW 18.1 32 bit is, after recreating it from scratch, OK
    18.2 64 bit I cant make anything writeable

    See my long post above listing the issues that starts with "created a brand new VM with Mint 18.2 64 bit Cinnamon"
    This is still true
    Using Mint 18.2 64 bit I cannot share any macOS drives with this VM

    In that post I see that Shared Folders mount points and the "keys.txt" are writable for user "npalardy". Where should I look for an issue?

    They look writeable
    But in reality they aren't - I get an error 100% of the time if I try to edit any of those files
    And trying to copy a file from the VM's desktop into any of these shared folders fails
    The appearances are 100% deceiving - I cannot write anything to those shared drives despite the listings suggesting that I should be able to

    Can I ask you to download and try out our virtual appliance with Linux Mint 18.2? Is your issue reproduced there?
    For this you should go to Parallels Desktop app menu -> New -> Free Systems -> Download Linux Mint?

    This says its going to download 18.1 (Serena) MATE (not sure about 32 or 64 bit)

    And, once downloaded, it has the same issue

    I need some more info from you.
    0. Please, generate problem report and post its id here. For this make VM window active and in Mac app menu go to Help -> Send Technical Data.
    1. Run these commands in host macOS and post their output here:
    diskutil list
    ls -ld /Users/*

    The problem seems to be in a group ID of your home directory in Mac. It has numeric value 501 which is invalid for your system. And sadly Parallels Desktop cannot handle such case painlessly for Linux guest Shared Folders. If my hypothesis is correct to workaround this problem you just need to fix group ID of your home: by default it should be "staff". For this just run this command in Mac terminal:
    sudo chgrp staff /Users/npalardy

    Thats very curious since this WAS working under Parallels 12 and the update made it stop working - but ONLY for this one VM
    All others continued to work as is
    I already was/am part of the staff group
    So chgrp was unnecessary
    I'll need to figure out how / why my home dir is set up weird - a chown npalardy:staff may be in order

    FYI, chgrp(1) doesn't change user's groups configuration. If modifies group ID of a particular file or directory.

    I realize that
    As I said I already WAS part of the staff group
    I made no changes to my account (which chgrp would do)
    Just the permissions on my home dir were odd
