Hi fellows,


Welcome to our website. This is the one and only website that belongs to us.


Please click here for simple and basic knowledge about OSX86 and iATKOS Project.



>> iATKOS Y is our Yosemite (OS X 10.10.5) release. You can request and download it by this page.


>> iATKOS M is our Mavericks (OS X 10.9.5) release. You can request and download it by this page.


Fusion Drive installations are now supported by our upcoming El Capitan release iATKOS EC. Support is also added to our Yosemite release iATKOS Y. No additional user actions needed.

Fusion drive is Apple's implementation of hybrid drive. It is simply combining a Hard Disk Drive and an SSD (Solid State Disk) with the space of both drives combined. Creating a Fusion Drive Volume is just like creating a Software RAID Volume.

The operating system automatically manages the contents of the fusion drive so the most frequently accessed files, applications, documents, photos and other data are stored on the faster flash storage (SSD), while the infrequently used items move to or stay on the hard disk drive. Simply, 1TB HDD + 128GB SSD Fusion Drive Volume gives you 1.1TB SSD speed drive in usage.

You can easily create your Fusion drive by using terminal in 2 steps. We will also create a GUI application to make it user friendly (also for RAID operations for El Capitan).


Hi Folks,

We have been working on El Capitan for a while and we will release iATKOS EC if/when it is good to go. No time frame but so far it is fine.

As we test El Capitan, it feels good. It uses the processor wisely. Even if it looks like Yosemite (besides the beachball and the new Disk Utility toy :), it feels different. Graphical interface (GUI) runs flawless on multi-tasking, no trace during high CPU loads.

Current version is 10.11.1.



iATKOS Yosemite 10.10.5 revision is released.

- Mac OS X 10.10.5 Build 14F27 (Latest Yosemite version)
- Clover UEFI/Legacy bootloader v2.3 r3262
- Chameleon bootloader v2.3 r2757

Click here to request and download the latest revision iATKOS Y.

New revision 10.10.5 images will be sent to new iATKOS Y requests by default.

All of our existing iATKOS Y users can request new 10.10.5 revision for free.


iATKOS Y new revision basic description:

Clover UEFI/Legacy bootloader updated to v2.3k r3252.

Additional improvements for:
- ATI Graphics cards
- Intel Pentium/Celeron G/J series CPUs
- X58/X79/X99 chipset motherboards

Minor improvements for:
- Broadwell Core i/M CPU laptops
- Some problematic
 laptop computers' booting processes which can only boot over USB3
- UEFI laptop booting
- Some other Clover legacy booting problems
- Network devices and some other drivers



We have added RAID Mode support for Intel SATA ports to iATKOS Y.

No need to set "SATA to AHCI mode" anymore, iATKOS Y can now work with both AHCI and RAID modes.

Here is the reason:

Some of (HP and Dell) laptop computers' Intel SATA mode is locked to RAID instead of AHCI. They do not have the setting in their BIOS menu. These computers can not install and run OS X easily. With iATKOS Y, they can.

Some people use Windows (yes they do) with Hardware RAID on Intel SATA ports with this RAID mode. They need to set their SATA back to AHCI mode every time they want/need to boot to OS X or install OS X. With iATKOS Y, they do not need to play with their SATA Mode anymore.



A small application to enable HiDPI on your monitor.

HiDPI is used on Apple's Retina Displays. It is the reason of the smooth view of Mac OS X on retina displays.

You can get it by this link.

Here is the source code.



This example below may shed a bit of light on smooth anti-alising desktop gui:


After our work on our Yosemite release iATKOS Y, we have updated our Mavericks release iATKOS M to version 10.9.5, the latest version.


You can find the short changelogs on previous post below.


By the time being, delays happened on sending your releases and also getting back to your emails from time to time..

Sorry for inconvenience and thank you for your patience..


Last few days' requests will be sent tomorrow..




We have released the new revision of iATKOS Y (10.10.3) and we are making a new revision of iATKOS M which will be OS X 10.9.5.


The new dmg installer images that boot with new system and install new system.


New revision of iATKOS Y includes 10.10.3 (Build 14D131) system. Short changelog:

- New system (From 10.10.1 to 10.10.3)

- Updated bootloaders  > Clover 2.3 r3201, Chameleon 2625

- Improved auto-detection, updated drivers

- New Broadwell CPU and Graphics (Intel HD 6000 series) support

- Some bug fixes > random UEFI boot failure on UEFI machines (no entrance sign), safe mode (-x) boot failures on some machines, safe mode (-x) EFI partition mount, Chameleon boot freezes on some machines, disabled false auto-hibernate, non-ahci sata boot problem etc.


New revision of iATKOS M will include 10.9.5 (Build 13F34) system. Short changelog:

- New system (From 10.9.1 to 10.9.5)

- Updated bootloaders  > Clover 2.3 r3201, Chameleon 2625

- Improved auto-detection and updated drivers

- Some bug fixes > random UEFI boot failure on UEFI machines (no entrance sign), safe mode (-x) EFI partition mount, disabled false auto-hibernate, etc.


Existing iATKOS M and iATKOS Y users can request new revisions of their releases for their target computers they have donated for.


Referring to changelogs and new system/bootloader versions, I recommend the new revisions to all of our users with booting, installation and other system problems.


New revisions of releases will be sent by default to new donators.




8 and 9 series motherboards and hibernation:


Hibernation is a bit different than normal sleep. It is deep sleep which is the power independent sleep. That means even the power is down, your data is safe during deep sleep, just like a shutdown. The need for removing the power cable (ie. moving your desktop to elsewhere) or if the power source is not a UPS, then hibernate would be a secure way of sleep. You like it after you have it.


If you want to try, keep on reading:

>> Only for 8 and 9 series desktop computers.

>> Only for Clover UEFI

>> You should have a proper configured installation for normal sleep (sleep to RAM) if you want to try deep sleep.

-- (Not needed for iATKOS Y / M installations) Mount EFI partition and delete OsxAptioFixDrv-64.efi from drivers64UEFI folder, unmount EFI partition and restart your computer.

-- Open Terminal and enter:

sudo pmset -a hibernatemode 29

-- Click "Sleep" by Apple menu.

-- After it is fully down, press Power button.

-- It will start normally and you will see your hibernated volume on Clover boot screen (as in the screenshot)

-- Press enter. It will wake up from deep sleep and you will jump to login screen or to your desktop without Apple boot screen.


>> If fails, it will just go into restart loop. If so you will have to cancel hibernation by pressing space bar, then it will boot normally.

Enter this on Terminal to disable hibernation:

sudo pmset -a hibernatemode 0





>> For any kind of OSX86 computer with successful normal sleep:

If your computer goes into reboot loops after hours of normal sleep, cancel hibernate boot by clover space bar menu and apply this line below after normal system boot. This diables auto-hibernate after long sleep hours.

-- Open Terminal and enter:

sudo pmset -a standby 0

 (This is applied on iATKOS M and iATKOS Y installations for our users not to lose data.)
