    It is best to have Sandy Bridge, Ivy Bridge, Haswell, or Broadwell
    Many people post here asking "Will my laptop work." I will try to address some of the general issues with laptops in this post.

    First off, I should mention that getting a laptop close to 100% functionality is always difficult (unless it is a ProBook 4x30s or 4x40s) and may not be possible or to the level you want. That's just because of the nature of laptops: you don't get to choose every hardware component (for OS X compatibility) like you can a desktop build.

    That said, most newer laptops are generally compatible with Mountain Lion mostly due to the fact that the base components are provided by Intel CPUs and the Intel 6-series or 7-series chipset. If your laptop has a Intel Sandy Bridge or Intel Ivy Bridge CPU using HD3000 or HD4000 graphics, chances are you can attempt to make the laptop work with OS X.

    Where the difficulty comes in is with all the other hardware and variables...

    Refer to the FAQ for additional information: http://www.tonymacx86.com/yosemite-...faq-read-first-laptop-frequent-questions.html


    General Notes:

    - CPU and chipset series: You need to know what exact CPU your laptop has. If it is Sandy Bridge it will have a model designation iX-2xxx*. If it is Ivy Bridge it will have a model designation iX-3xxx*. Haswell (supported starting with 10.8.5) is iX-4xxx*. You should also note your chipset version, currently either 6-series, 7-series, or 8-series. A mixed configuration (eg. Sandy Bridge CPU on 7-series chipset) is more difficult to configure than one that isn't mixed.

    - Discrete graphics: Many laptops that have AMD Radeon or Nvidia GeForce discrete graphics utilize a switching mechanism to switch from integrated graphics (Intel HD) to the discrete card when the situation demands. This type of switching does not work in OS X and generally it means disabling the discrete capability in BIOS. If your BIOS does not allow it to be disabled, it can complicate the installation procedure (you may have to delete the related kexts). Also, it is possible that the discrete card is still drawing power even though you are not using it in OS X, so try to find a laptop without discrete graphics.

    - WiFi: There are a limited number of WiFi chips supported by OS X drivers. In addition, OS X's WiFi driver architecture is not documented, so there are not very many WiFi driver "Linux ports" to OS X. There are some useful links for OS X WiFi in this post: http://www.tonymacx86.com/hp-probook/97099-wi-fi-bluetooth-cards-laptops-mac-os-os-x.html. In addition, some BIOS implementations have implemented a whitelist where only certain cards can be installed into the laptop, perhaps only cards branded specifically by the manufacturer of the laptop. Sometimes, the whitelist can be disabled via a hacked BIOS, but sometimes the BIOS is encrypted. The service manual for your laptop may give you a list of compatible cards and if one of those happens to also be compatible with OS X, then you can search for such a card and try replacing it. Some of the more compact laptops (Ultrabooks) have WiFi soldered onto the motherboard or combined with another componenent (mSATA SSD), making replacement more difficult or expensive. In many cases, the specific WiFi chip included with the laptop is not specified when you purchase.

    Note: Compatible WiFi chipsets and the procedures for making them work are covered here: http://www.tonymacx86.com/network/104850-guide-airport-pcie-half-mini-v2.html. Any WiFi chips not listed are not supported and must be replaced.

    - Ethernet: Ethernet is generally built-in to the laptops motherboard. And since OS X Ethernet driver interface is documented there are quite a few open source drivers available. Usually you can find one that works, but not always.

    - Audio: Getting audio to work generally depends on finding or creating a patched AppleHDA (for best results and stability, don't use VoodooHDA except as a last resort). Although patching AppleHDA for any audio codec is possible, it is very involved, requires technical skills you may not have, and is time consuming.

    - Camera: Most built-in cameras are USB, some are connected to USB2 and some to USB3. Some will work, some won't. There is no pattern, and there is no way to tell until you try.

    - Card reader: Some card readers are on the PCI bus and have OS X drivers available from the manufacturer (certain Jmicron devices, for example). Some are on the USB bus and might work using the class driver built-in to OS X. You won't know until you try.

    - Bluetooth: Sometimes bluetooth is built-in to the WiFi card (on the USB bus) and sometimes it is somewhere else (on the motherboard?). Bluetooth is always a rough spot on any OS X hack, so it may not work how you would like.

    - Battery status: Battery status is possible to make work by using an ACPI compliant AppleSmartBatteryManager.kext. I generally recommend my own kext: https://github.com/RehabMan/OS-X-ACPI-Battery-Driver. Most DSDTs will need patching to
    work correctly with the vanilla AppleACPIPlatform.kext (and the latest AppleACPIPlatform.kext is required for Ivy Bridge power management). The patching required is often specific to the laptop family and requires some programming background to accomplish (unless you find a patch has already been done for you).

    - Keyboard/Trackpad: Most laptops use the PS/2 interface for the keyboard and trackpad. OS X has no support for the PS/2 interface, so you will need to install drivers for it. What trackpad you actually have in your laptop determines which version you seek out. And most of the time, the trackpad manufacturer is not specified... sometimes varying even with the same model of laptop. There has even been a case of a laptop being sent out for repair and coming back with a trackpad from a different vendor.

    - DSDT: Most laptops will require DSDT edits to get various laptop features working. You should be prepared to learn about DSDT patches, MaciASL, how to install to /Extra/dsdt.aml, etc. Don't fall into the trap of downloading a DSDT for another laptop. Find patches and patch your own. Native DSDTs can vary between laptops even that are the same model.

    - BIOS: Some BIOS implementations are picky about booting. For example, some will not boot legacy mode to a GPT drive. OS X generally requires to be installed to a GPT drive, so this can be a problem. There are workarounds, but sometimes this can be difficult for the non-technical to understand.

    In short, hacking a laptop is a challenge. You should not expect it will be easy. And there are many different laptops, each with unique configurations, BIOS, hardware combinations, etc. It is always possible that a given laptop will not work even if the hardware mentioned above seems to meet the requirements.

    And if you want 100% compatibility with a discrete graphics capability, perfect bluetooth and no hassles, don't look to a hack... buy a MacBook Pro.


    Note on gen1 Core i-series CPUs

    These laptops generally use "Intel HD Graphics" which are not supported very well by OS X. But some report getting it to work. There is a relatively extensive write up here: http://www.insanelymac.com/forum/topic/286092-guide-1st-generation-intel-hd-graphics-qeci/. YMMV.


    Note on Haswell systems

    There is widespread reports of the OS X kernel (mach_kernel) rebooting early during initialization on some Haswell systems (especially laptops). From my understanding, this is due to the kernel now doing power management in the kernel (XNU CPU Power Management, or 'xcpm') for these systems instead of in AppleIntelCPUPowerManagement. There is no known solution to this problem at this point.

    Update, see here: http://www.tonymacx86.com/mavericks...-locked-msrs-hp-envy-15-j063cl-i7-4700mq.html


    Note on Broadwell systems

    Broadwell is subject the same XCPM issues as described above for Haswell.

    In addition to that there are some common issues that arise from changes in the graphics drivers for Broadwell that, for most laptops, require the ability to change the DVMT-prealloc setting in BIOS. Most laptop BIOS implementations do not provide this setting in their menus, but it can be set using a special UEFI shell.

    See here for early Broadwell work:

    SMBIOS info: http://www.tonymacx86.com/yosemite-laptop-support/164292-smbios-broadwell.html#post1040286


    Note on Skylake

    Although there is limited Skylake support in current El Capitan builds, it requires a number of work arounds and there are currently no Apple product using Skylake integrated graphics. As a result, the graphics drivers are not done and your chances of getting a PC Skylake laptop with Intel integrated graphics working are not good.

    More info on Skylake: http://www.tonymacx86.com/desktop-compatibility/176407-testing-thread-skylake-platform-os-x.html

    Early reports are that 10.11.4 has enhanced support for Skylake integrated graphics. As on Broadwell, DVMT-prealloc must be set to 64mb (or larger).


    Note on Samsung Laptops and eDP displays

    It seems many Samsung laptops have an eDP connection to the laptop LCD, instead of the more common LVDS. The drivers in OS X for HD3000 and HD4000 do not support eDP. So avoid such Samsung laptops or at least verify whether it is eDP or not.

    Evidently there is support for eDP in the HD5000 (HD4400/HD4600) OS X drivers, so eDP on Haswell systems should be better supported.

    Thanks. I mostly wrote it out of self interest... as a go-to post to make it easier to respond to "Will my laptop work?" kind of questions.

    Nice you found it useful.

    Should be a "must read" before trying anything. This post is a good preparation paper.

    Thanks for this post. :) I'm kinda having problem because I wanted to buy a new/used laptop that is compatible with Mac OSX. My main goal is to use Adobe Suite in a hackintosh laptop.

    I'm eyeing for a Dell Inspiron 17 3721 or 17R 3721 / Asus and MSI or maybe HP. can you suggest anything here?

    I also have ASUS K43SJ i3 2nd gen.

    Cheers!:thumbup: TYIA :D

    You would have to list the specs.

    For the Dell Inspiron - http://www.ebay.com/itm/NEW-Dell-In...77027036?pt=Laptops_Nov05&hash=item5af62a58dc

    i3-3227U 3rd gen
    17.3"
    500GB HDD
    8GBDDR3 (I plan to do a 16GB here)
    Intel HD 4000 Graphics

    For other laptops I'll still look for stores nearby - I wanted to have a dedicated graphics card working to render some 3d software. I won't use Dual boot, It will be single boot and I have parallels to do windows inside the hackintosh.

    If you have other suggestions on laptop I'll find stores here in my country and try to find that specific model. As it might be difficult to find it here. My budget is around $600 for the machine including the extras like if wireless card needs to be replaced.

    My sole purpose is to use this as a portable work machine (small video editing, powerpoint stuff, adobe suite software, 3d software via parallels) Thanks again mate! :thumbup:

    You should be able to get that Dell to work (standard Ivy Bridge/HD4000 laptop). Read post #1.

    Finding a laptop with dedicated discrete graphics is relatively difficult. Most laptops sold these days have "switchable" where the only possibility in OS X is the onboard (Intel HD*).
