If your Mac needs a firmware update and it isn't installed automatically, check to see if a manual updater is listed below.
If the firmware version you see in System Information is newer than what's listed for your Mac, you don't need to apply the updates listed for that model.
Mass production of that new machine will begin in Q2 of this year, according to Kuo, while a 16GB memory option will also be added to the device.
Meanwhile, my USB drive had the disk4 identifier, so I type of=/dev/rdisk4 (don't forget the letter "r" before the identifier). This will probably take 15-30 minutes, though it may take longer, depending on the speed of your USB drive.
Distros are a popular Hackintosh alternative to Unibeast, a better-known installation tool which requires a retail copy of Mac OS X instead.
If you don't have any qualms with the legal issues regarding distros, they're actually the most convenient way to set up your Hackintosh. This command will output a list of drives currently connected to Mac OS X, including your USB drive.
In addition to a new CPU you may also need other additional components (new heat sink, thermal paste) and to upgrade your motherboard BIOS.
You can upgrade the CPU to a faster clock speed, or dual CPUs instead of a single CPU (20 Mac Pro only).
If you're interested in running Mac OS X, but you don't want to pay ridiculous prices for a normal Mac, then a Hackintosh just might be for you.
Right now, the newest iteration of OS X is 10.9, known as Mavericks.
Assuming that 12 cores are better than 6 cores can sting: once when you pay extra for the “faster” system, and then in diminished performance for as long as you own the machine.
By the same token, 12 CPU cores can offer a major benefit for some programs.
In general, a fast clock speed is best for most users, but whether 12 cores is better than 4/6 cores depends very much on the specific tasks involved.
Upgrading the CPU is relatively expensive; you’re better off buying a faster Mac up-front, because Apple can offer the fastest CPUs more cost effectively than is possible through any upgrade service (Apple gets a very large discount on some very expensive Intel CPUs).
