i discovered a better option by myself

 

ubuntu 10.10 for example reads osx partitions but doenst write , i discovered is becouse user permitions

 

if i use nautilus in SUDO mode i can write in osx partitions :D

 

example open console and type:

 

sudo nautilus

 

now you can read/write in osx partitions (non-journaled only)

That is a VERY VERY DANGEROUS approach! I STRONGLY advise against it! The problem is two-fold. First, you're running the Nautilus file manager as root, which means that you can do immense damage to Linux and/or OS X by a sloppy mistake, such as clicking the wrong confirmation button, dragging files to the wrong location, etc. Second, when you copy files and create subdirectories, they'll probably be owned by root, which means you may need root access to make further changes, which means you'll be creating a requirement for yet more root access, thus increasing future risks.

 

Instead, you should synchronize your user ID (UID) numbers, and perhaps your group ID (GID) numbers, across Linux and OS X. This can be done with the usermod command in Linux, along with a chown command to change ownership of your regular files:

 

sudo usermod -u 501 yourusername
sudo chown -R 501 /home/yourusername

 

It's conceivable you'll need to log out and back in again between those commands. (In fact, this is best done via a direct root login, but Ubuntu disables this type of access by default.) You may need to adjust the UID value (501 here) to something else, depending on what you use in OS X. You will obviously also need to change "yourusername" to something appropriate.

 

When this is done, you should be able to read and write all the same directories on your HFS+ partition(s) in both OSes from a regular login, without using a dangerous sudo operation every time.

    • For F6 Bios, which DSDT is the one i should use? I´m a little confused in the Mass of DSDT here ;-).   Great Thread by the Way.   Another Question: I have 2 960Pro inside my Rig (one with OS X, one with Windows 10). When i try to mount my EFI on OS X NVMe the system freezes... :-(   DWhen i unplug the Windows NVMe everything is fine an it mounts the EFI.   Anybody an idea?   Tried the upper Port on the Board (OS X) & the middle / lower Port, in the Middle it mounts the EFI in the lower it freezes.   But i need the middle Port for an SATA M.2 SSD :-D... Even when i plug the Windows NVMe into an PCIe Adapter Card it freezes at the point i mount the EFI.   I´m mounting with Clover Configurator.     Thank You guys.
    •   Just add "ngfxsubmit=0" to config.plist to disable the fix within nvidiafixup
    • @MegaCookie   ok, I have no solution for that Trial 7 good for the release?
      Is this codec good enough for you?
    • @onejay09  - thanks again for your help and advice.  I tried various combinations of Info.plist mods (Adding a new Machine entry with my Board ID and GFX0, adding GFX0 to the MacBookPro6,1 Machine entry and adding a Vendor/Device entry to the Board ID and MacBookPro6,1 Machine entries. I thought these might make a difference, but after comparing GPU temps and frequencies to those reported in Windows 7, I'm not seeing any difference.  It appears as though AGPM is natively detecting and handling power management of the NVidia Quadro NVS 140m without any Info.plist mods.   Thanks again.
    • My rig is not booting without the "XCPM bootstrap patch" and "xcpm_program_msrs (c) Pike R. Alpha" patch. Already tested that.  Booting without the TSCAdjustReset.kex is working great and booth sleep and wake is working. The new bios 0603 has an updated microcode. That might be the reason  for the fact that everything is working as it should without the kext.
