How to Read and Write to NTFS partition in Mac OS X

(Originally Posted in http://blog.tolik.org By Anatoliy S Okhotnikov )

This Tweak Adds the NTFS Write feature in MacOsX (Experimental):

This tweak is tested on MacOsX 10.6.7 - 10.7.0 (This May or Not Work on Lower Versions and some users have reported that similar tweaks have led to data loss or ntfs partition rendered unaccessible, So "PROCEED AT YOUR OWN RISK" )

It has the ntfs.kext binary from the Mac OS X 10.6.8 Snow Leopard and a script. Unpack it to the Desktop. You should get the NTFS_Enabler folder with two files: mount_ntfs and ntfs. Launch Terminal.app and Proceed as Below ->

1) Type sudo -s and press Enter. Type in your password and press Enter.

2) Make backup copy of the ntfs.kext binary (!this is a one line command!):

mv /System/Library/Extensions/ntfs.kext/Contents/MacOS/ntfs /System/Library/Extensions/ntfs.kext/Contents/MacOS/ntfs_orig

3) Copy ntfs.kext binary from Mac OS X 10.6.8 Snow Leopard replacing the original one (!this is a one line command!):

cp ~/Desktop/NTFS_Enabler/ntfs /System/Library/Extensions/ntfs.kext/Contents/MacOS/ntfs

4) Create a backup copy of mount_ntfs:

mv /sbin/mount_ntfs /sbin/mount_ntfs_orig

5) Now place the new mount_ntfs binary which activates ntfs.kext for rw:

cp ~/Desktop/NTFS_Enabler/mount_ntfs /sbin/mount_ntfs

6) Fix the scripts rights and attributes:

chown root:wheel /sbin/mount_ntfs

and then:

 chmod 755 /sbin/mount_ntfs

7) Launch Disk Utility and repair permissions. Reboot after this operation.

Package has a text document(Terminal-CMD) with the commands line by line, as the blog engine might break some lines. After the reboot the NTFS partitions must be mounted read-write without any additional fixes and reboots! In case anything goes wrong you can roll it back with the backed up copies.

Finally Installed MacOsX On My Laptop

After Days of experimentation with many MacOsX distribution i finally found one which actually worked on my dell inspiron 1545 laptop.
But after installation : Sound , Wifi, Battery Monitor was not working and graphics was set to 1024x768

I tested many drivers and had many kernel panics but finally found some drivers that worked. still I'm unable to find graphics card driver and also laptop touchpad goes out of control sometimes.

I mainly got info from
http://wiki.osx86project.org

http://ihackintosh.blogspot.com

http://www.insanelymac.com/

If you are planning on installing OsX86 on your Pc or laptop you better findout the MacOsX version compatible for you Machine
You can find the Compatibility list from this link http://wiki.osx86project.org/wiki/index.php/Main_Page

Things i followed while Installing Mac And After installation:

1) Start installation in Safe mode and verbose mode. Just pass -x -v flags to kernel before you load the installation

2)During installation click customize and  make sure you have ps2 kext clicked, In begining i had not clicked it and my laptop's keyboard was not working and i had to work with external usb keyboard but then i found the problem.

3)Right after finishing the installation , boot the installed OS with -x and -v flag and after you have setup user account and logged in then reboot and boot in  normal mode, I found many times that after installation if i boot in normal mode it usually hangs.

4)Use kexthelper application for installing kext file(drivers)(kernel extention)

5)If you dont have working audio after installation search for VoodooHDA.kext for your laptop hardware online it worked for me.

6)And for broadcom wifi device i used IO80211Family.kext you might find one for your device if you do similar search

7)I used VoodooBattery.kext for laptop batter monitor .

8) I would recommend you first install windows and then install MacOsX as in mac boot loader even windows drive is shown and you can select windows partition to boot at OS selection menu of MacOsX
but if you install Mac first and then windows . Mac Mbr will be deleted and then you have to install extra software's like EasyBcd and configure to make MacOsX Appear in OS choice menu

9)Install Macdrive software (By MediaFour) in Windows , by using this you can easily access Mac Partition in Windows . So if you had installed a driver and it caused kernel panic ,you can boot to windows and browse Mac partition and go to System \ Library\ Extentions and find that kext file you recently installed and just delete it and now boot you MacOsX with -x -v flags (safe and verbose mode) and if it boots properly then reboot in normal mode.

10)After installing updates i usually faced kernel panic ,so right after update i used to boot with "-x -v arch=i386 -F" flags and it used to boot successfully. and try deleting dsmos.kext and sleepenabler.kext after installing the update in case you still get kernel panics as these two are usually main cause for kernel panics as far as i noticed.

This is all the tips I have for anyone who is interested in installing MacOsX on their PC or Laptops
If you Like Mac Buy it.
Thank You
