This is a collection of DSDT/SSDT patches and tools for the ASUS UX305FA laptop for OS X 10.11 El Capitan.
It requires Clover r3328 or later.
If you're not interested in the details of DSDT patching, skip ahead to the "Intro" section.
If you've used other guides, you're probably familiar with the process of DSDT.dsl patching, using a tool like MaciASL.. This guide doesn't do that. Instead, it uses a different approach for ACPI patches: RehabMan's "hotpatch" style. The special clover.plist works together with small SSDT files to accomplish the same purpose as text-based DSDT/SSDT patching.
This set of hotpatches should work across BIOS revisions of the UX305FA. (It looks like it may work on the Broadwell-based 303LA and LB as well.)
Clover supports binary "search&replace" patch operations on DSDT/SSDT tables. Even simple binary patching can be very powerful.
_DSM methods are renamed to XDSM, which nothing calls.GPRW can be replaced. First, the original method definition is renamed to an unused name like XPRW. Then, a separate small SSDT provides a replacement "GPRW" method.Later in this guide you will install SSDT files. The only files you should expect to see in EFI/CLOVER/ACPI/patched are these:
| File | Description |
|---|---|
SSDT-HACK.aml |
Brightness keys, USB, graphics properties, HDMI sound |
SSDT-BATT.aml |
Battery monitorying |
SSDT-DEBUG.aml |
ACPI logging |
SSDT-ALS.aml |
Ambient light sensor. Optional. |
SSDT-RMNE.am |
MAC address for NullEthernet. Optional. |
SSDT.aml |
CPU power management. You will create this after installation with ssdtPRGen.sh. |
Do not include DSDT.aml or any of the numeric SSDT-1.aml files. They will cause trouble.
These instructions are broken into two sections. The first, "Building", needs to be done on a working Mac. The second, "Target", is run on the UX305FA.
Clone or download UX305FA-DSDT-Patch from GitHub.
In this directory, the command sh download.sh will download a collection of drivers into downloads/. If you don't have iasl on your PATH, unzip it from downloads/tools/ into tools/, which is on the PATH for the Makefile.
For your UX305FA, you may later need a builtin Ethernet device (for the App Store, for example). If so, edit the Makefile and uncomment the USE_NULLETHERNET=1 line; then edit SSDT-RMNE.dsl to include a MAC address not in use by anyone. The MAC address of the factory WiFi card is a reasonable choice.
To build the AML files from DSL source, type make.
After sh download.sh and make, you will later copy this whole directory, UX305FA-DSDT-Patch, to the destination machine.
Create your 10.11 installation USB drive according to [RehabMan's guide] (http://www.tonymacx86.com/el-capitan-laptop-support/148093-guide-booting-os-x-installer-laptops-clover.html). Some notes:
Because we're using the GPT format, the EFI partition on the USB installer is not automatically mounted when the drive is inserted.
There is a quirk in the Clover installer: after installing to USB, the USB EFI partition may be mounted at /Volumes/ESP.
If you want to mount the USB EFI partition at another time:
/Volumes/EFI already exists, use diskutil unmont /Volumes/EFI to unmount it.diskutil list to find the disk number of the USB drive, like disk1diskutil mount /dev/disk1s1 to mount the EFI partition at /Volumes/EFIOn the USB EFI partition, the only directory in EFI/CLOVER/kexts should be Other. EFI/CLOVER/kexts/Other should only contain FakeSMC.kext (from downloads/kexts/RehabMan-FakeSMC-2015-1230.zip) and ApplePS2SmartTouchPad.kext (from SmartTouchPad_v4.4_Final_64bit.zip).
RehabMan's config file [config_HD5300_5500_5600_6000.plist] (https://github.com/RehabMan/OS-X-Clover-Laptop-Config/raw/master/config_HD5300_5500_5600_6000.plist) is a good choice for config.plist. Change Graphics/Inject/Intel to false for initial installation.
There should not be any files in EFI/CLOVER/ACPI/patched yet.
You will need these files handy on the target machine: the UX305FA-DSDT-Patch directory you prepared, FakeSMC.kext, ApplePS2SmartTouchPad.kext, HFSPlus.efi, and the Clover installer. Copy them to a USB drive. If you do not have another USB drive handy, you could copy those files to a folder on the Install OS X El Capitan disk.
To get into the BIOS on this machine, press ESC while the "ASUS" logo is on screen.
Reset the BIOS settings to default with the menu item "Save & Exit: Restore Defaults".
Under "Security: Secure Boot menu", set "Secure Boot Control" to Disabled.
Under "Boot", set "Fast Boot" to Disabled, and "Launch CSM" to Enabled.
Under "Advanced", set "VT-d" to Disabled.
Under "Advanced: Graphics Configuration", set "DVMT Pre-Allocated" to 128M.
Don't forget to "Save & Exit: Save Changes".
Follow [RehabMan's installation guide] (http://www.tonymacx86.com/el-capitan-laptop-support/148093-guide-booting-os-x-installer-laptops-clover.html#post917904).
Once you've reached "Post Installation" in RehabMan's guide, you'll need to copy the files described in "Copying files to USB" to the Desktop. After copying, I recommend ejecting all USB drives at this point.
There is currently a bug in the trackpad driver: scrolling will not work until you have opened System Preferences:Trackpad, and changed "Scrolling speed" at least once. It can be difficult to navigate the Clover installer without scrolling.
Install Clover as described in the guide.
There is a quirk in the Clover installer: after installing, the EFI partition may be mounted at /Volumes/ESP.
Otherwise, to mount the hard drive EFI partition:
/Volumes/EFI already exists, use diskutil unmont /Volumes/EFI to unmount it.diskutil list to find the disk number of the hard drive. It is very likely disk0.diskutil mount /dev/disk0s1 to mount the EFI partition at /Volumes/EFIBecause there will be an EFI partition on both your installation media and the hard drive, mounting the right EFI partition can be tricky. It is less prone to human error if you don't have any USB disks plugged in.
After installing Clover, remember to install HFSPlus.efi, FakeSMC.kext, and ApplePS2SmartTouchPad.kext to the hard drive's EFI partition as you did with the USB install media.
This is where you install the hotpatches.
From the UX305FA-DSDT-Patch directory, copy build/*.aml to the EFI partition's EFI/CLOVER/ACPI/patched directory.
The AML files completely depend on DSDT/SSDT patches done by Clover according to the config.plist. Copy build/config.plist to EFI/CLOVER/config.plist.
If you have the 1920x1080 display, config.plist is done. See the next section if you have a QHD/UHD display.
I hate the ambient light sensor, and its driver has never worked quite right for me. Feel free to remove EFI/CLOVER/ACPI/patched/SSDT-ALS.dsl.
Once you're done with this section, you should be able to reboot from the hard drive.
(Skip this section if you have the FHD/1920x1080 display.)
If you have the QHD/UHD display, the config.plist option Graphics/Inject/Intel set to true will cause a hang at boot until you have patched IOKit. Turn off Intel injection by setting Graphics/Inject/Intel to false until then.
To patch IOKit on QHD/UHD machines, I use macPixelClockPatcher.command from [floris497's repository] (https://github.com/floris497/mac-pixel-clock-patch).
OS upgrades tend to overwrite the IOKit patch, which can make your QHD/UHD machine unbootable with injection. You can disable Graphics/Inject/Intel for a single boot using Clover options. On the main Clover screen, press O to bring up Options, choose Graphics Injector menu then press space on the InjectIntel option. Press ESC twice and boot normally. Once you're in the OS, you can re-run the IOKit patcher.
I recommend not logging into any Apple services until you have completed this section and the next.
On the target machine, you can run sudo ./install_downloads.sh in this UX305FA-DSDT-Patch directory to set up kexts. This installs:
ACPIBatteryManagerACPIDebugApplePS2SmartTouchPad v4.4 (4.5 doesn't work as well on UX305FA)AsusNBFnKeys v2.4 (matches v4.4, try a later version for ALS)BrcmPatchRAM2 and BrcmFirmwareRepoFakePCIIDFakePCIID_Broadcom_WiFi (for DW1560)FakeSMCIntelBacklightNullEthernetThe kexts will be installed into /Library/Extensions.
NullEthernet will only be loaded if you edited the Makefile and SSDT-RMNE.dsl.
In this UX305FA-DSDT-Patch directory is AX88772-USB-Ethernet.dmg, which is a driver for the USB Ethernet dongle which comes with the UX305FA. Note that it appears to replace the Apple USB Ethernet driver. It does come with an uninstall/restore script.
Sound won't work without a driver. There are three choices for that:
The VoodooHDA installer is available in downloads/pkgs/.
The directory voodohda-fix contains a patch for headphone detaction. See voodoohda-fix/readme.txt.
Mic switching is unsupported.
Thanks to anerik70, there is a patched AppleHDA. It also supports HDMI audio (with the current config.plist). I have not tested it as much.
The dummy kext is in ADummy.kext.zip. You can install it with sudo unzip -X ADummy.kext.zip -d /Library/Extensions. If you installed VoodooHDA previously, remember to remove /System/Library/Extensions/AppleHDADisabler.kext.
Like this VoodooHDA, this particular AppleHDA does not support mic switching. If you feel like messing with it, https://github.com/Mirone/AppleHDAPatcher/tree/master/Patches/Laptop/CX20752 may have useful files.
McShmoopy has built a hybrid VoodooHDA/AppleHDA configuration, which handles both internal and HDMI audio. See http://www.tonymacx86.com/el-capitan-laptop-support/185868-voodoohda-jack-sense-auto-switching-hdmi-audio.html for details.
You still need CPU power management. See [the Beta branch of Piker-Alpha/ssdtPRGen.sh] (https://github.com/Piker-Alpha/ssdtPRGen.sh/tree/Beta). (The master branch will not work.) The SSDT.aml it generates needs to go in the EFI partition's EFI/CLOVER/ACPI/patched directory.
To improve performance and to (potentially) enable Apple services, you need SMBIOS information configured. You can add appropriate SMBIOS settings to EFI/CLOVER/config.plist, probably using a tool like Clover Configurator. This guide does not cover the subject, but a good choice for ProductName is MacBookAir7,2.
You're done!
Most drivers are downloaded as part of download.sh. Here are the sources for the other drivers:
The command to force-enable HiDPI mode is
sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool trueOn the 1920x1080 display: in order to use HiDPI mode at resolutions above 960x540, you need [SwitchResX] (http://www.madrau.com/srx_download/download.html). Select your monitor, switch to the "Custom Resolutions" tab, then use "+" to add "Scaled" resolutions at twice the size you really want. "3200x1800" gives a virtual 1600x900 display.

Machanical's guide to the similar UX303LA was helpful. http://www.tonymacx86.com/el-capitan-laptop-guides/172279-guide-asus-zenbook-ux303la-broadwell-edition.html
EMlyDinEsH maintains the touchpad driver.
RehabMan seems to maintain...just about everything else. :-) He also convinced me to try the no-patch DSDT technique.
