PC and i wants to install Mac OS X mountain Lion.well windows 7 is. I tried it for many times but i unable to do it so, by bootable usb. I want to install OS X Mountain Lion on my PC but my mother board (Asus IPIBL-LB) does not support USB boot, even after flashing bios with the last update. Is there a way to install OS X 10.8 on PC without USB boot? I want to install OS X Mountain Lion on my PC but my mother board (Asus IPIBL-LB.

No idea whether your motherboard is compatible with OSX. Does your system use integrated graphics or the 8600GT graphics card?

If the former, it is not supported in OSX. If you are using the 8600GT graphics card in the system, then you can first try to install Mac OSX Snow Leopard using iBoot (available from the download section) and the Snow Leopard retail DVD (still available from Apple). If it works, you can then update Snow Leopard to 10.6.8 and then purchase and download Mountain Lion from the Mac App Store.

Then you can upgrade the system to Mountain Lion directly without using USB boot. I suppose you already have Windows on this system? If so you will need to wipe out your hard disk to install OSX.

Are you OK with that? Yes I just found this option in the computer's Bios (ide/raid/ahci). But when I set it to AHCi (instead of Raid, by default) and choose 'save changes and quit', my computer brutally shut down (instead of rebooting). When I reboot, Windows (8) does not start correctly and a blue screen appears.

I had to return to the Raid option and wait for a (very) long Windows repair before it works again. I read that on Windows AHCI drivers must be installed first in order to activate this option from the Bios. Could you confirm that? However, I'm a little bit afraid of this ahci option. I dont want to lose my data on my Windows drive. Yes I just found this option in the computer's Bios (ide/raid/ahci).

The new aluminum iMac is thinner than the old one. Unlike the, there is no longer a 17″ model – only and models. Three models use a Core 2 Duo Merom CPU (a 24″ 2.8 GHz Core 2 Extreme model was available as a build-to-order option) with the same Santa Rosa chipset and 800 MHz bus found in the Mid 2007 MacBook Pro models. They have three USB 2.0 ports, FireWire 400 and 800 ports, gigabit ethernet, 802.11n WiFi, and an upgraded SuperDrive – as well as a brand new slim aluminum keyboard with USB 2.0 ports.

The 20″ 2.0 GHz iMac ships with 1 GB of RAM, a 250 GB hard drive, an 8x SuperDrive, Radeon HD 2400 XT graphics, AirPort Extreme, Bluetooth 2.0, and Apple’s new keyboard and Mighty Mouse. The 2.4 GHz models ship with a 320 GB hard drive and use Radeon HD 2600 Pro graphics. The new iMac ships with and iLife ’08. This is the oldest iMac that supports and later ( and later are free, and is the last version supported). The Radeon HD 2400 and 2600 Pro graphics processors, while better than the Radeon X1600 GPU in the previous generation 2.0 GHz iMacs in some respects (and worse in others) is a step down from the Nvidia GeForce 7300GT and 7600GT in the earlier 24″ iMac.

Gaming benchmarks measure GeForce frame rates as anywhere from 20% to nearly 200% higher. There are also many complaints about reflections due to the glossy display. Although it is not officially supported, the Mid 2007 iMac can run macOS Sierra using Colin Mistr’s Sierra Patch Tool if you replace its Merom CPU with a Penryn CPU. Even then, WiFi is not supported on this device.

What You Need to Know While 1 GB of system memory is plenty to run OS X 10.4 Tiger comfortably, it is just adequate for and truly inadequate for, which isn’t happy with less than 2 GB. For, 2 GB is a starting point and 4 GB will make you happier. And really call for 4 GB, and and want the 6 GB maximum Mid 2007 iMacs support – even though Apple says Yosemite will run with 2 GB. More RAM always makes OS X run more smoothly. The CPU is in Socket P and uses an 800 MHz FSB (front side bus). Upgrades as high as 2.8 GHz are possible (see ).

Note that 20″ aluminum iMacs use an 18-bit LCD, which can only display 262,144 colors, not the “millions” all other iMacs can display. Free dvd burner for mac. This should be good enough for most users. Unlike earlier iMacs, where every USB port could provide 500 mA of power, only a single high-powered device can be attached to the USB ports, and software will enable one of its downstream ports to supply 500 mA of power. If a second high-powered device is attached, it will behave like a normal bus-powered hub and only provide 100 mA per downstream port. Intel-based Macs use a partitioning scheme known as GPT. Only Macintel models can boot from GPT hard drives. Both PowerPC and Intel Macs can boot from APM (Apple’s old partitioning scheme) hard drives, which is the format you must use to create a universal boot drive in Leopard.
