I just installed Mac OS 10.13.6 with unibeast and im new to hackintosh generally. Everything Works fine except the graphics acceleration. The window, Launchpad and dock Animations Look glitchy and are slow. How to I fix this? My laptop Specifications are: - Lenovo flex 2-15 - Intel. Intel Core i5-4440 Haswell Quad-Core 3.1 GHz (3.3 GHz Turbo) LGA 1150 84W BX0 Desktop Processor Intel HD Graphics 4600. Apple Mac Mini Desktop - Intel. Haswell is the codename for a processor microarchitecture developed by Intel as the 'fourth-generation core' successor to the Ivy Bridge (which is a die shrink/tick of Sandy-Bridge-microarchitecture). Intel officially announced CPUs based on this microarchitecture on June 4, 2013, at Computex Taipei 2013, while a working Haswell chip was demonstrated at the 2011 Intel Developer Forum.

More than a year after introducing the first Retina MacBook Pro at the 2012 Worldwide Developer Conference, Apple has announced that the computers will be getting a refresh at today's media event. The most significant update to the new models' specifications comes from Intel's brand-new Haswell processors, which should improve the battery life significantly compared to their Ivy Bridge-based predecessors.

Updates to both the 15-inch and 13-inch models were revealed today, which gets the two models on the same refresh schedule. (The 15-inch model was originally introduced last June at the 2012 WWDC, but the 13-inch model was introduced last October.) The 13-inch laptop starts at $1,299. The 15-inch model starts at $1,999. Both models ship today.

The upgraded 13-inch Macbook Pro comes with a 2.4GHz (2.9GHz Turbo) Core i5, 4GB of DRAM, a 128GB SSD, and Haswell's integrated Iris GPU. This means that the baby Macbook Pro finally has a better GPU than the MacBook Air—the 2560×1600 screen will continue to soldier on with integrated graphics, but the Iris 5100 GPU should be a decent step up in performance from the HD 5000 GPU in the Airs.

Haswell

The new 15-inch Retina MacBook Pro is a logical upgrade over last year's model. The entry-level Retina MacBook Pro now uses a Haswell-based quad-core 2.0GHz Core i7 CPU that can Turbo Boost up to 3.2GHz, while the high-end model uses a 2.3GHz (3.5GHz Turbo) part by default. Both laptops can be upgraded to 2.6GHz (3.8GHz Turbo) CPUs at purchase. To power the laptop's 2880×1800 display, Apple swaps out the Nvidia GeForce GT 650M GPU in last year's model for an upgraded GeForce GT 750M with 2GB of GDDR5 graphics RAM in the high-end models, though the lower-end models will only include the Intel Crystalwell (that is, Iris 5200) integrated GPU. The GeForce 700M GPUs are architecturally similar to their predecessors, but higher clock speeds and tweaks to that architecture should be good for a decent performance boost. As in last year's models, OS X can dynamically switch between the integrated Intel GPU and the dedicated Nvidia GPU based on workload to save power.

Intel says that Haswell should enable big jumps in general-usage battery life, and to that end Apple has increased the battery life figures for the 13-inch Retina MacBook Pros from seven hours to more than nine hours. The 15-inch manage a more modest eight hours.

Like the MacBook Air and 2013 iMac before it, the MacBook Pros are also picking up 802.11ac wireless networking (the adapter will continue to connect to 802.11n, g, b, and a networks). Both models also include higher-bandwidth Thunderbolt 2 ports. The 13-inch model has dropped a bit of weight and slimmed down, to 3.46 pounds and 0.71 inches.

And what of the non-Retina MacBook Pros? There's just one left: a non-Retina 13-inch model at $1199, and it hasn't been upgraded from last year's Ivy Bridge configuration. That means a 2.5GHz dual-core i5, Intel's integrated HD 4000 GPU, and yes, a 500GB mechanical hard drive. The 15-inch non-Retina device appears to have been put down, though. Rest easy, old friend, and say hi to the white plastic MacBook for us when you get to that farm upstate.

We will continue to update this post as more information becomes available.

Buying a new Mac is exciting, but it can also be very confusing. For most of the Macs it sells, Apple offers a number of different configuration options, including different RAM capacities, storage sizes and disk types, and processors. For many people, it’s the last of those that’s most important. It’s arguable that processors, or CPUs, are now so powerful that they can do everything most of us need to do at a speed that is more than good enough and so choice of CPU isn’t important. But that’s not quite true, as we’ll explain below.

What is a processor?

Put simply, a processor is the ‘brain’ in your Mac. Until relatively recently the CPU was responsible only for taking input, executing instructions and passing on the results. Now, CPUs incorporate short-term memory of their own and, sometimes, graphics processors, or GPUs. In fact, when it comes to choosing a processor for your Mac, deciding whether to opt for one that has an on-chip graphics processor is one of the key decisions you’ll have to make. Macs that have processors with on-board GPUs tend to be less expensive than those that have separate graphics processors, but also are less capable when it comes to things like rendering 3D graphics and 4K video. To further complicate matters, new macOS features like Metal make excellent use of the hardware in GPUs, meaning the choice of graphics processor is almost as important as the choice of CPU.

What processor does my Mac have inside?

Since 2006 all Macs have used Intel processors — unlike iPhones and iPads which have Apple processors. Apple labels the Intel CPUs it uses in the Mac as Core i5 and Core i7 and differentiates them by speed in GHz. The other difference is the number of cores in the CPU and the number of CPUs in the Mac. So, roughly speaking a quad-core processor should be able to process instructions at twice the rate of a dual-core CPU. That’s not the case in the real world, as executing instructions relies on more than just the speed at which the CPU’s ‘brain’ can perform calculations (for example, it’s dependent on how quickly those instructions can be passed to and from the CPU). However, in an application optimized for multiple cores, you should notice a significant difference between CPUs with different numbers of cores.

Intel gives each generation of its processor a code name. Recent Intel CPUs have had names like Sandy Bridge, Haswell, and Skylake. Apple doesn’t use those names, or even talk publicly about which processor is in each Mac, but it’s known that the current crop of iMacs and MacBook Pros have Kaby Lake processors, which were the most recent available at the time they were released in 2017. So, if you bought it in the last year or so, your MacBook Pro processor is Kaby Lake. The slimline MacBook processor is known as Core M, designed specifically for low power mobile use. The MacBook Air and Mac mini have Haswell processors, as they were released in 2013. The Mac Pro uses a completely different family of Intel processors, designed for high-end workstations and known as Xeon. The Mac Pro, last updated in 2013, uses the Romley variant of Xeon.

What are the important features of a processor?

We’ve already talked about processors that have on-board graphics, such as Intel Iris and Iris Pro. These offer benefits such as taking up less space than discrete CPU and GPU chips and Mac’s that use them tend to be less expensive than those with separate CPU and GPU. However, they also tend to be less powerful.

Haswell

The other key feature of a processor is the balance between speed and power consumption. CPUs that run faster use more energy and so generate more heat. This doesn’t just mean that fans have to run more often, it also uses more power — and if the Mac is a laptop, runs the batter down more quickly. Indeed, CPUs are often ‘throttled’ so that they don’t run at their theoretical maximum, in order to preserve battery life and reduce heat generation.

What about Turbo Boost?

Turbo Boost is a technology introduced by Intel and is designed to allow processors to run at speeds faster than those quoted on your Mac’s label in certain circumstances. Remember we said that CPUs are often throttled to prevent overheating? Turbo Boost monitors the power consumption and heat of the CPU and removes that throttle when it’s safe to do so. So, for example, a quad-core 2.8GHz Mac Pro could run as fast as 3.8GHz in the right circumstances.

Which processor should I choose?

It’s likely that if you’re buying a new Mac, you’re choice of processor will be made from the Core M, Core i5, and Core i7. Not all Mac models offer a choice of all three. The Core M, for example, is specifically designed to minimise power consumption in mobile devices and is used only in the MacBook. If you’re buying a MacBook Pro or iMac, you’ll have the choice of Core i5 or Core i7. Likewise, if you buy a MacBook Air or Mac mini, although those machines use older versions of Intel processors. And, as we said earlier, if you buy a Mac Pro, you’ll be able to choose from Xeon workstation processors with multiple cores.

There are two decisions you’re likely to have to make: i5 or i7 and dual-core or quad-core. Generally speaking, in terms of speed, a dual-core i5 is the slowest and a quad-core i7 the fastest. That, however, is not the whole story. In order to get the most from multiple cores, you’ll need to be performing tasks that really benefit from the ability to execute more instructions simultaneously. So, tasks like 3D rendering, video editing and working with large images in Photoshop will all improve noticeably with a quad-core vs a dual-core processor.

Core i7 processors have two main benefits over Core i5: larger cache and hyper-threading. The presence of a larger cache means the CPU can store more data locally and so spend less time transferring them back and forth to RAM. Hyper-threading allows the CPU to simulate additional cores. So, a quad-core i7 with hyperthreading behaves like and eight-core CPU.

The benefits of larger cache and hyperthreading are seen in scientific applications, where large calculations are performed and their results stored, as well as the 3D animation and 4K video editing.

Integrated vs discrete graphics

As we discussed earlier, some Intel processors have GPUs onboard. In some Mac ranges, such as the MacBook Pro and iMac, you’ll have the choice of a model with integrated graphics or one with a separate, or discrete, GPU. If you’re going to use your Mac primarily for playing power-hungry games, manipulating large images, or editing video or animation, you should choose a Mac with a separate GPU. On the other hand, if you’re mostly going to use it for writing, email, social media and editing your own photos, a CPU with integrated graphics, like Iris, is fine.

Can I upgrade the processor in my Mac?

That’s a flat no, sadly. There have in the past been Macs that had processors that could be upgraded, but now they’re soldered firmly in place and so your Apple CPU can’t be removed. That makes the choice you make when you buy your Mac even more important. The good news is that for most users every processor that ships with a currently available Mac, even those that haven’t been updated in several years, is absolutely fine and will run as fast as you need it to.

If I can’t upgrade the processor, how else can I speed up my Mac?

Two of the most effective ways to make your Mac go faster are to install more RAM and swap your hard drive for an SSD. Those both cost quite a bit of money, however. A much less expensive and much easier way is to get rid of the ‘junk’ files that can clog up your Mac. These are installed by applications, or by the system, or downloaded to your machine by websites. Deleting them one by one is a long and difficult process, but CleanMyMac X makes it very easy. CleanMyMac identifies files on your Mac that either serve no purpose, that you’re unlikely to need, or that are large and haven’t been opened for a while.

You can scan your Mac with one click and CleanMyMac will report back to you with the files it thinks you can delete and how much space it will save you — it can be tens of gigabytes. You can then review them and choose which to get rid of or press Delete and get rid of them all. CleanMyMac also makes it easy to uninstall apps you no longer use and removes all their associated files. You can download it free here.
