Diskpart, before the resize, didn't show me the OSX partition. Now, Diskpart show me as RAW Fs.
Can this help you?
Don't use DiskPart to try and resize the macOS partition. It's okay for Windows.
If you can boot - either the main drive or a UniBeast USB stick - run Disk Utility to check all is okay with macOS.
The El Capitan version of Disk Utility can also resize a partition BUT it will wipe the Windows one you have. A safer way may be to use a third-party application. There are many Partition Managers out there that claim to resize without damaging any data. I only have experience of Paragon Software's Partition Manager, but you will need to make your own choice here. Read all the documentation you can.
