Hardware Compatibility Information of iATKOS ML3U (Mac OS X Mountain Lion 10.8.3): CPU: - 2nd generation Intel Core i series newer processors including Ivy Bridge and Sandy Bridge are supported. 2nd and 3rd Generation Core i3, i5, i7 / Xeon 3xxx, 5xxx, 6xxx, 7xxx, E3, E5, E7 - AMD CPUs are not supported. Motherboard: - Please read with attention and do not continuously ask questions about your motherboard compatibility. - Most of UEFI Intel chipsets motherboards are supported. - Non-UEFI motherboards are not supported. - Besides the main chipset model, a motherboard has many components. Every component itself may or may not be compatible and even may be problematic for Mountain Lion. Also, BIOS of the motherboard may be problematic to run Mountain Lion. Because of these reasons, some motherboards will not be able to run this OS easily, some of them will need hard efforts in order to make it partially work and some of them will never run it. GPU: - Intel Graphics HD 3000 and HD 4000 are supported, the rest are not. - nvidia vga cards from G80 core to the newest kepler series (G80, G84, G86, G92, G94, G96, G98, C79, GT200, GT215, GT216, GT218, GF100, GF104, GF106, GF108, GF110, GF114, GF116, GF119, GK104, GK106, GK107) are supported on 10.8.3. This does not mean that all of them will work of course but most of them will work OOB with iATKOS ML3U. Some of them will work with issues (some are known issues and some may not be) and some of them may not even work. You will have to try and see it yourself. Simply, nvidia 8xxx / 9xxx / 1xx / 2xx / 3xx / 4xx / 5xx / 6xx cards are supported. - About ATI, 7xxx support has come with 10.8.3, so some of the 7 series ATI will work. Most of the supported ATI 7xxx/6xxx/5xxx/4xxx cards only work with modified drivers for each of them. Users will have to take the additional steps to use such cards after installation. Network Devices: - Common wired and wireless network devices that are auto-detected by iATKOS ML. There may still be problematic chips but most of them will work OOB with iATKOS ML. Wired: - Intel Gigabit and Intel Pro/100 - Realtek RTL8111/8168 - Atheros AR8121/AR8113/AR8114/AR8131/AR8151/AR8161/AR8171/AR8132/AR8152/AR8162/AR8172 - Broadcom BCM57780, BCM57781, BCM57785 - Marvell 88E8035, 88E8036, 88E8038, 88E8039, 88E8056, 88E8001 Wireless: Some chips (ie. Atheros ar5008, Broadcom BCM4311) are natively supported by OS X. So, this is not the complete wifi support list of OS X. - Atheros 9285, 9287, 9227 - Broadcom 4312, 4321, 4322, 43224, 43225, 43227, 43228 (Some of these broadcom chips need rebranding in order to work on OS X.) RAM: - Recommended minimum amount of RAM is 1GB. Disk Space: - Recommended minimum amount of disk space for installation is 15GB.
