Hackintosh USB mapping - attempt to fix broken Bluetooth

UPDATE 2: My attempts at “fixing” USB mapping broke all the USB 3.x ports. None of the USB 3.x ports work. I did set them to “Type 3” which is “USB 3 Standard-A connector”. Undoing all the USB mapping stuff fixed my non-functioning USB ports. Everything works OK, including Bluetooth. No idea why: everything about OpenCore is still kind of a mystery to me.

UPDATE: Bluetooth fixed itself. What I did: booted into Windows (installed on a separate SSD), used Windows to connect to the speaker, quit Windows to boot into Hackintosh, and Bluetooth works again. Quick way to see that Bluetooth is OK is that System Information on the Bluetooth device should show a non-trivial address. If it were broken, the address would be 00-00-00-00-00-00.

tl;dr This did NOT fix my Bluetooth issue. I had also cleared the CMOS and re-set all the BIOS settings before I went through all of this. So, this may be of some use as a summary of USB port mapping in OpenCore, but of no use at all for fixing Bluetooth issues.

Bluetooth stopped working for unknown reasons. Discovered that Bluetooth is actually an internal USB device.

Suspicion: the breakage is due to the macOS 15 USB port limit. (Additional USB hubs get their own 15-port limit.)

Follow instructions:

  • https://dortania.github.io/USB-Map-Guide/
  • https://github.com/corpnewt/USBMap

Using the USBMap script, can see that there are 26 ports listed: HS01 - HS14, USR1 - USR2, SS01 - SS10. (This is the same as the list that corpnewt has on their system.)

The script allows you to disable all SSxx ports and all HSxx ports. Then, manually enable a specific set of HSxx ports. From this post at tonymacx86, someone has listed the USB ports for this motherboard: back panel, and internal headers. I have verified this is correct, for the ports that I can use. I have no USB Type-C devices, so I cannot check the two USB Type-C ports on the rear panel.

The case I am using has no front-panel USB Type-C ports, so I can leave HS01 disabled. I do not currently have any USB 3.1 Gen 2 Type C devices, but I am planning to get at least one: I will enable both HS08 and HS13. I will leave the internal Bluetooth (HS14) enabled. There is no HS02 shown in either diagram, and none of the ports I could test were HS02: so, disable that. There was no USR1, either, but the USBMap documentation does not say anything about enabling or disabling USR* ports, so leave that enabled.


  • Two disabled HS ports: HS01 and HS02

That leaves me with 12 HS ports, and 2 USR ports, bringing me up to 14 ports.

The boot-args option is:

debug=0x100 keepsyms=1 alcid=1 agdpmod=pikera -uia_exclude_ss -uia_exclude_hs uia_include=HS03,HS04,HS05,HS06,HS07,HS08,HS09,HS10,HS11,HS12,HS13,HS14,USR1,USR2

Back at the main menu of USBMap, pick “S. Build SSDT-UIAC”, which will generate two .aml files:

  • SSDT-UIAC.aml
  • SSDT-USBX.aml

Copy those to your EFI/OC/ACPI folder, edit your config.plist to add them to the ACPI section, and reboot.


  1. Disable all ports named “SS* - using USBMap script, select “S. Exclude SSxx Ports. This appends the boot option -uia_exclude_ss to NVRAM which will persist across reboots. NB this does not modify config.plist. In OpenCore 0.5.9, this step did not work for me. So, manually modify config.plist to add the boot option (NVRAM->Add->...long string of chars->boot-args). Manually trying to set boot-args using the nvram command gives an error: “nvram: Error setting variable - 'boot-args': (iokit/common) not permitted”. So, set it in config.plist, instead.
  2. Download SSDT-USBX.aml from USB-Map-Guide/extra-files
  3. Use SSDTTime to generate SSDT-EC.aml. (Had SSDT-PLUG.aml from initial install.)
  4. Copy the .aml files into EFI/OC/ACPI/
  5. Add entries for both SSDT-USBX.aml and SSDT-EC.aml into config.plist

Hackintosh update - WiFi card added

I wanted to have Handoff on my Hackintosh. That requires WiFi.

The built-in WiFi on the Gigabyte Z390 Designare motherboard does not work with macOS. But Dortania, the people who work on OpenCore, have a list of recommended WiFi devices. I got an ASUS PCE-AC68 AC1900 Dual-Band Wireless PCI-E Adapter. And it just worked. I did not have to add more kexts or munge my config.plist.

Another point for OpenCore.

However, Handoff does not work. It seems like I need a Bluetooth adapter with a particular chipset. The ones that are pretty certain to work are ripped out of actual Macs: they use the Broadcom BCM94360CS2 or BCM94360CS (one person had better luck with this) chipset, and combine WiFi with Bluetooth. There are also generic adapters: search eBay for that product string. These are M.2 form factor. Since I wanted the second M.2 slot on my motherboard for a Windows installation, I could not go this route.

Migrating from Aperture to Lightroom Classic

I built a new Hackintosh, and am now running macOS Catalina (10.15). Since Catalina only runs 64-bit applications, I am finally forced to migrate all my photos from Aperture to Lightroom Classic. 

tl;dr Make Aperture store its masters as “referenced”. Split the library into smaller ones, no more than about 10,000 masters per library. (A 27,000-master library took > 24 hours to import.) Import into Lightroom, keeping Aperture masters in place, and copying Aperture-edited previews into the masters’ location to allow automatic stacking. 

The Aperture import plug-in that comes with Lightroom Classic is not great. If you have a very large library, it can get very slow. No one who has very large libraries seems to have waited. My library is about 700 GB, with about 560 projects and 81,500 images. I kept the library “managed” i.e. Aperture copied everything into its library package. I tried to import the full Aperture library into Lightroom Classic. After 5 full days (24 hours per day) of running, the import into Lightroom seemed to stall at 50%. From the start of the process, every additional percentage point seem to take longer and longer. (Felt like an N² algorithm or worse.) Others have had the same experience (Adobe support community forum post).

Without resorting to a manual import (aka “the Old Method”), as the person who posted that issue in the Adobe forum did, I figured I would try the latest suggestion posted there, i.e. to break up the single original library into multiple smaller libraries. That seems to be working pretty well. 

To export in Aperture: File ▶ Export ▶ Items as New Library… Then, in the options: 

For this to work, your Aperture masters folder must have the same absolute path on the old computer and the new computer. My old computer’s Aperture masters (originals) folder was at: /Volumes/Homes/Users/myname/Pictures/Masters
On my new computer, I needed to make sure that my home folder was on a separate volume, such that it ended up with the same absolute path /Volumes/Homes/Users/myname/Pictures/Masters. I had tried one iteration, where my new home folder was in a slightly different location /Volumes/Homes/myname and that did not work because Lightroom Classic complained that the folder /Volumes/Homes/Users/myname/Pictures/Masters was missing. It is not the fault of Lightroom Classic, since the absolute paths are encoded in the exported Aperture libraries.
You also want to make sure the previews are copied into the exported library. Otherwise, Lightroom Classic would not have access to those (edited) previews.
To import into Lightroom Classic: File ▶ Plug-in Extras ▶ Import from Aperture Library…. There is an Aperture Import Info… menu selection which gives some info about the import process. A window will pop up, showing four sections.
The first section is “Previews from Aperture”. There is only one option, “For images which have been adjusted in Aperture, import full size previews from the Aperture library (if they are available and up-to-date)”: check that ON.
The last one, is “Files referenced in Aperture”. Here, check ON “Leave referenced files in your Aperture library in their current location”. If you have checked on “import previews”, a second option should be available: “For referenced images left in their original location, place version previews in the same folder as the master image to allow for automatic stacking”. Check this ON, too.
In short: import previews ON, leave referenced files in current location ON, place version previews in same folder as masters ON. Really, ALL options are checked ON.

Click “OK”. As a check, you should see that the “Disk space required” value should be small, indicating no additional space for the masters will be used. It should just be the additional space to accomodate the previews.
It will return you to the first window, where you can click “Import” to start the import. How long it takes seems to depend on the number of images in the library. I didn’t time any of the imports, but a few thousand masters with maybe a thousand previews took maybe 2 or 3 hours. Certainly not the multiple days that a naïve import took.

Setting user home directory in macOS via command line

My old Hackintosh was messed up: it mounted the separate drive holding the Home directories in "/Volumes/Homes 1" rather than "/Volumes/Homes". That meant I could not login normally.

But, I was still able to login via ssh. Since macOS is a Unix-ish system, it just drops you in the root directory. From there, do the following:

    sudo dscl . -change /Users/username NFSHomeDirectory old-path new-path

Replace username, old-path, and new-path with appropriate values.

Migrating from Aperture to Lightroom Classic drops non-destructive adjustments layer

Well, this sucks: according to Apple, migrating Aperture RAW files to Lightroom Classic does NOT migrate the non-destructive adjustment layer. Which means my 650 GB or so of photos are the unedited versions. 

The old Hackintosh is dead. So, I can’t go in and re-export edited JPGs. But even if I could, I wouldn’t do that: who’s got the time?

New Hackintosh using OpenCore



I now have a new Hackintosh. My old Hackintosh was completed at the end of 2012. And for the last year or so, it has been running really slow. I also managed to kill the GPU slot a few years ago, due to my usual impatience. So, it had been running with the on-board Intel GPU. However, I was still able to play League of Legends on its lowest quality graphics mode, all credit to Riot Games.

This build was rather frustrating: I decided to use OpenCore, as it seemed (last fall) to be the future of Hackintosh. I had all parts in hand last November. I worked on the build a bit at a time over the last few months, but kept running into issues. E.g. fixing the "slide" value for KASLR, random crashes, black screens, etc.

In any case, all the bits and pieces sat around for a few months. I finally installed Windows on its own HDD, and had been running it for a few weeks. Finally decided to take a look at OpenCore, again. I ended up using OpenCore 0.5.9. The documentation had also been tidied up a bit, and it seemed a little easier to follow this time around.

It took me only a couple of days to get everything up and running, stably and consistently.

Here is the parts list:

Additionally, I re-purposed an old 2.5" 500 GB HDD that I had lying around from an old used Mac Mini that I destroyed. (Did I mention that I tend to destroy hardware due to impatience?)

Before I go into some detail about the process, here is a short rundown on what works and what doesn't:

  • Messages works
  • FaceTime may work -- I don't have a webcam, so I can't confirm
  • iTunes works
  • AppleTV does not work due to DRM issues (HDCP, I think?)
  • Netflix on Safari does not work, again due to DRM
  • Netflix on Google Chrome works, but at 720p, I think (it does not look like 1080p)
  • YouTube 4K works
  • Audio (analog) input and output jacks on rear and front panels work; the rear panel jacks appear as "built-in"
  • On-board Bluetooth works
  • On-board WiFi does not work
  • Blu-ray reading/playing does not work. Have not tried burning. UPDATE July 2020: need to consult the motherboard documentation. Installing M.2 storage may disable one or more of the SATA ports due to sharing of data lanes in the chipset. Now, reading/playing/ripping CDs works fine, playing DVDs works fine, ripping DVDs with Handbrake works fine (install libdvdcss using Fink), reading Blu-Ray works but can’t play them (of course), MakeMKV recognizes the Blu-Ray but hit a “fatal error” when trying to rip.
  • Steam games pretty much do not DO work (updated Jul 20, 2020 - not sure what has changed, but Steam games seem to work, now)
  • League of Legends works (Teamfight Tactics is what I'm playing most, nowadays)

Here is what I did. There is a lot of detail follow in the official guides, so I will just present an outline, and the key hardware-specific things I had to do.

I also found the diagrams in this forum post useful, even though it uses TonyMacx86, since they use the same motherboard.

  1. Create USB flash drive installer.
    1. You will need a 16 GB USB flash drive.
    2. This can be done on macOS (including a Hackintosh), Windows, or Linux. Here is another guide for doing this on Windows.
  2. BIOS settings. There are a variety of settings to make: first, "Load Optimized Defaults" as a starting point.
    1. Use UEFI boot mode
    2. Disable the following:
      1. Fast Boot
      2. VT-d. N.B. can be enabled if you set DisableIoMapper to True.
      3. CSM
      4. Thunderbolt
      5. Intel SGX
      6. Intel Platform Trust
      7. CFG Lock (MSR 0xE2 write protection). This may not exist in your BIOS.
      8. All RGB lighting
    3. Enable the following:
      1. VT-x
      2. Hyper-Threading (technically irrelevant, since the i7-9700 does not do hyperthreading)
      3. Execute Disable Bit
      4. Above 4G decoding
      5. EHCI/XHCI Hand-off
    4. Set OS type to: Windows
  3. OpenCore setup on the USB flash drive.
    1. This is probably the most tedious part: setting up OpenCore in the EFI folder, and creating a config.plist file.
    2. However, if you use the ProperTree OpenCore config.plist editor, quite a bit of the work is automated.
    3. NB some of the text instructions in the OpenCore guide do not match up with the pictures which illustrate the instructions. If there was a conflict, I took the text to be authoritative, and ignored the pictures.
  4. Once OpenCore config.plist is done, save a copy of that config.plist (I add a date-time stamp to the backup copy). Then, reboot from the USB flash drive, and run the macOS Installer.
    1. For the initial install, I installed on the NVMe boot drive. I selected APFS format.
  5. Post-install, set up the new Hackintosh boot drive with its own EFI partition so that the installer USB flash drive is no longer needed. 
    1. Optionally, set up a GUI for the boot device selector
    2. Fix the audio interface: find the appropriate PCI ID for the device. The motherboard includes a Realtek® ALC1220-VB codec. I used layout 1.
  6. Once it was installed, I ran Disk Utility to format the data HDD for use as my home folder.
    1. I suggest formatting HDD as HDFS+. My experience with APFS on a HDD in my old Hackintosh is that APFS on HDD is pretty slow, particularly when backups run and a snapshot is created.
    2. Then, follow these instructions to set a new location for the home folder.
    3. Reboot, and make sure the new home folder works.
    4. Apply any OS updates.
  7. I have a Time Machine backup HDD in a USB enclosure. I hooked up the backup HDD to the new Hackintosh, and used Migration Assistant to move OS and applications. Since my home folder on the old Hackintosh and the new Hackintosh are not on the same device as the boot drive, Migration Assistant was not able to transfer the data.
    1. I tried mounting the old HDD containing the home directory using USB on the new Hackintosh, but was unable to see any of the data at all. I didn't spend too much time to figure out why: after about 30 minutes trying a couple of obvious tricks, I bailed.
    2. The old Hackintosh was started up with the home folder HDD attached. I used rsync to transfer the data. NB you will likely need a newer version of rsync than what comes with macOS Catalina. This is because I ran into errors using the default rsync: it had trouble with some extended file attributes. Compilation was straightforward; standard GNU style: ./configure ; make ; make install

Late addition based on post-install experience: Do not bother with USB mapping unless you find one or more USB ports that you need are not working. Things just seem to work.

And that was pretty much it.
