Indeed, even after you’ve purchased a Mac, the information about the exact CPU model is hidden from the “About this Mac” and System Information windows. This is fine for most users, but power users or those looking to compare a Mac’s performance to an equivalent PC may want to know exactly which CPU is powering their computer. Thankfully, third party resources, such as the excellent, have stepped in to provide a wealth of details about.
But to use that information, you’ll first need to know your specific Mac model and then take the time to browse the website. What if you just quickly want to verify your Mac’s CPU model? Or what if you’re working to repair or troubleshoot someone else’s Mac and don’t have all the info about the system immediately available? Well, you’re probably not surprised to learn that there’s a Terminal command that can show your Mac’s CPU model. Here’s how to use it.
First, launch Terminal from the Macintosh HD/Applications/Utilities folder (or by searching for it with Spotlight). Then, enter the following command and press Return: sysctl -n machdep.cpu.brandstring You’ll immediately see a new line of text with the exact make and model of your Mac’s CPU. In our example, our 2013 Mac Pro is powered by a single Intel Xeon E5-1650 V2. A quick search for that processor reveals its listed at Intel’s website, including important information such as and price. Intel has kept the same naming scheme for several years, meaning that lots of CPUs share similar frequency characteristics even though they offer far different performance levels.
I read somewhere that there's actually a problem with the PMU that if it thinks the CPU is speed x, it won't allow the system to go faster than that speed. 867Mhz 12' Powerbook OS X Panther 10.3.1 Xbench 1.1.3 I created a new account just for this test. This is mostly because my primary account has a bunch of stuff running in the background. Cpu Z Os X, free cpu z os x software downloads. The Web Help Desk software for Mac OS X offers an industry leading web-based help desk software feature set that allows you to dynamically assign, track and fulfill all of your technical support trouble tickets and customer service requests with.
By identifying your Mac’s specific CPU, you’ll be able to more accurately compare your Mac to other Macs and PCs, helping you either make an initial purchase or decide if it’s worth it to upgrade.

Pretty much any Intel Core processor will work with Mac OS X, so almost all mid-range Hackintosh builds use Intel Core. The newest Intel Core processors are part of the (4th gen), while older generations include (3rd gen) and (2nd gen). Sandy Bridge processors have model numbers in the 2000's, such as the Intel Core i5- 2500. The built-in graphics cards on Sandy Bridge processors work with Mac OS X Lion and Mountain Lion (but not Snow Leopard), and come in two versions: HD 2000 and HD 3000.

Unfortunately, only HD 3000 graphics. HD 2000, but it doesn't have graphics acceleration, so it's recommended that you just buy a separate ('discrete') graphics card for your computer instead. Nowadays, most Hackintosh builds use Ivy Bridge. Ivy Bridge processors have a model number in the 3000's, such as the Core i5- 3450. Mac OS X Lion 10.7.5 and all versions of OS X Mountain Lion support Ivy Bridge natively. Snow Leopard doesn't support Ivy Bridge at all, though you might be able to. HD 4000 graphics, which is built into some Ivy Bridge processors,. Intel HD 2500, the successor to Intel HD 2000,.
The Haswell generation of Intel Core processors is supported natively by OS X Mountain Lion 10.8.5 and all versions of OS X Mavericks and Yosemite. You can probably also install Snow Leopard on a Haswell computer by using, although it's not recommended as a long-term solution. Haswell processors have a model number in the 4000's, such as the Core i7- 4770. They include built-in graphics cards, which come in two versions: HD 4600 and HD 4400.
HD 4600 graphics work with OS X Yosemite, Mavericks, and Mountain Lion (version 10.8.5 and above). HD 4400 does not yet work in Mac OS X. The highest end Intel Core processors are known as 'Sandy Bridge-E', 'Ivy Bridge-E', or 'Haswell-E'. Sandy Bridge-E processors have model numbers in the 3800's and 3900's, such as the Intel Core i7- 3820. Meanwhile, Ivy Bridge-E processors have model numbers in the 4800's and 4900's, and Haswell-E has numbers in the 5800s and 5900s. Mac OS X does not completely support these processors, because they use a different socket from the rest of the Intel Core line. CPU power management and sleep mode only work for Ivy Bridge-E processors in OS X 10.9.2 and newer.
And even then,. Sleep mode and CPU power management are only guaranteed to work for Sandy Bridge-E processors in OS X 10.9.0 and newer. Haswell-E processors aren't officially supported in any version of Mac OS X at all (which means no sleep or CPU power management), but you can still get those processors to work in OS X 10.9.4 (and newer) with. P.S. Intel Sandy Bridge processors don't work very well with Mac OS X Snow Leopard version 10.6.8. I recommend that you update to version 10.6.7 instead. You can still update to Mac OS X Lion from 10.6.7 (updating to Mountain Lion requires 10.6.8, but you might be able to circumvent this requirement by ). Intel Pentium/Celeron.
When it comes to Mac OS X compatibility, Intel's Pentium and Celeron processors are a mixed bag. Unfortunately, the newest Pentium and Celeron processors (from the ) are not supported in either OS X Mavericks or Yosemite., in general, it's a no-go right now. However, if you're putting together a budget Hackintosh, then using one of the older-generation Pentium or Celeron processors isn't necessarily a bad idea. These processors use mostly the same underlying architecture as their higher-end Intel Core counterparts. For instance, the uses the LGA1155 socket, which is also used by Intel Core processors in the Sandy Bridge and Ivy Bridge generations. As a result,. However, Mac OS X compatibility for extremely old Pentium and Celeron processors (think pre-2010) will vary widely, since most of these processors use different CPU sockets.
In some cases, it comes down to which motherboard you're using. In other cases, the processors themselves may simply be too old. For instance, produced before 2008 are 32-bit CPUs, meaning that they don't work with Mac OS X Lion or Mountain Lion, which are 64-bit operating systems. Unlike the integrated graphics cards found in Intel Core processors, the integrated graphics cards in Pentium and Celeron processors don't work with Mac OS X. This includes Intel's GMA series of integrated cards. You can that allow Intel GMA to display Mac OS X at higher resolutions, but there's no way to enable graphics acceleration. Instead of using integrated graphics, you will have to buy a separate graphics card for your Hackintosh.
The situation for Intel Xeon processors is pretty much the same as that for Intel Core processors, since both lines use the same underlying architecture. This means that Mac OS X supports all Intel Xeon processors designed in the past few years. Like Sandy Bridge-E and Ivy Bridge-E, Intel Xeon is not completely supported in Mac OS X because it uses different sockets from the mainstream line of Intel Core processors. While you can still boot Mac OS X from a computer using an Intel Xeon processor, sleep mode and CPU power management will not work. You'll also probably have to perform, in order to get everything working properly.
If you don't mind that, then the next big challenge is finding a good motherboard. Since Intel Xeon processors are designed for servers, and few people ever bother installing Mac OS X on a server, there are very few successful Xeon Hackintosh builds that can set an example for future builders. Unless you really need the extra cores in Intel Xeon processors, just buy a high-end Intel Core processor for your Hackintosh instead. Don't buy an AMD processor if you ever want to turn your computer into a Hackintosh. The problem with AMD Hackintoshes lies in the kernel, a critical file that lets applications in Mac OS X communicate with the hardware of your Hackintosh.
The standard kernel for Mac OS X (known as the 'vanilla' kernel) is only designed to support Intel processors. Technically, you can. You just need an AMD kernel- a modified version of the vanilla kernel that works with AMD processors. However, using modified kernels is a tricky business, and no matter how you spin it, an AMD Hackintosh will never be as stable as its Intel counterparts.
Even if you get Mac OS X to install, that's only the first step. In fact, the subject of setting up an AMD Hackintosh deserves a whole other website by itself. To put it one way, unless you're a fan of self-flagellation,.
Conclusion The Haswell generation of Intel Core processors is a great choice for any Hackintosh, especially with the newest versions of Mac OS X. If you're looking for something really cheap, the newest Intel Pentium and Celeron processors work very well with Mac OS X, as well. However, try to avoid Intel Xeon, Sandy Bridge-E, Ivy Bridge-E, or Haswell-E processors, unless you're okay with some extra work (and the possible need for experimentation). Most of the time, simply buying a mainstream Intel Core processor will be a safer decision. In addition, AMD processors are a pain to work with on Mac OS X, and should be avoided whenever possible.
