Hi fellows,


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


iATKOS is an OSX86 Installation Project. This is the easiest way of trying Mac OS X on Intel based regular computers, also known as Hackintosh computers.

>> iATKOS EC is our El Capitan (OS X 10.11.2) release. You can request and download it by this page.


>> 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.


Apple has released 10.11.3 update. Backup your important data before trying the update.


- To update your existing El Capitan installation to 10.11.3, use App Store to try the update rather than the full 1.47 GB dmg updater. This way, your computer will have more chance to survive after the update :)

>> Good news, iATKOS EC installations on Skylake computers can apply the update (by using App Store as mentioned above).

>> If you used "USB Port Patch A" package during installation, then you may lose some of your USB ports after update. Try re-installing iATKOS EC with "USB Port Patch B" package and then apply the update after installation.

>> Some computers which can not operate without "USB Port Patch A" should not apply the update. We will release 10.11.3 revision of iATKOS EC soon.

>> After updating, do not forget to delete AppleHDA.kext that came with the update.

>> After updating, as usual, NVIDIA Web Driver users will need to update it too.




- 1st priority of our operations is development, as it always had been. Team is trying to give you the best!

- 2nd priority is release requests with priority service and questions/help requests of priority service users.

- The 3rd one is release requests with default service.

- 4th one: Any kind of questions/help requests related to iATKOS M / Y / EC.


Due to our operation algorithm, especially in times of development from time to time, we may delay responding to your requests 2-3 days more except for the priority service. We'll get back to your requests and questions eventually, we do not miss even one of them. This is all for making a better release.





New revision iATKOS EC is good to go! System version is 10.11.2 (Build 15C50).

- 10.11.2 revision iATKOS EC images will be sent to new requests from now on.
- Existing iATKOS EC users can request their new revision images by just filling and sending us iATKOS EC request form.

Last few days' requests will be sent tomorrow (GMT0), delay happened due to 10.11.2 revision..

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.
