This is a basic guide to get AMD Ryzen systems working in High Sierra. You can create a USB installer following the link below or use the Kernel link to manually edit a cloned or copied disk with High Sierra already installed. 1). To create a USB installer follow the link here and then add/replace the Ryzen pre and post install folders after installer is finished and follow the guide for post instal using the kernel_ext_install_only terminal command option. http://www.insanelymac.com/forum/topic/325514-amd-high-sierra-kernel-release-and-testing/page-24?do=findComment&comment=2519914 2). To use the disk edit method download the link materials and follow these basic instructions to add kernel and system kext. First you will need a HDD or SSD with High Sierra installed. it can be copied using carbon copy cloner or Super Duper, pulled form a working Hackintosh ( intel) or a fresh install. You will need a way to connect your test disk to a working Mac or Hack like a USB to Sata or if you have a Sata connection available use it. Step 1). Open system used to edit the disk and go to top tool bar and select "Finder" scroll to "Preferences" click it. Check the Hard Disk box, this will show all drives on the desktop along with EFI partitions during the edit. Name your test disk something like Ryzen so that it doesn't get mistaken for your working system drive. Be especially careful when loading clover to the drive check the Change Install Disk option and make sure you only load it to the Ryzen drive. Step 2). Open the kernels folder from the link in downloads and drag it to the desktop. Next open the risen disk now showing on desktop. Click on the System folder, then Library folder. Now scroll down to "Extensions" folder and click on side arrow to open. Leave this folder open but move the window to one side of the screen or the other so you can access it during edits. You will be going from the Kernels folder to Ryzen disk folder so its best to set them side by side for the edits (see pic). Open the Kernels folder on desktop and open the Extensions folder. Drag the "System Kext" to the "Extensions" folder on the Ryzen drive. You will get "Authenticate" and a "replace" set of options do both. If you don't get the "replace" option then hit cancel and repeat until you have the replace option before using password. Step 3). Close the "Extensions" folder tab arrow and scroll down to Kernels folder and click on arrow tab. Next go to Kernels folder on Desktop and drag the kernel to the Ryzen drive kernel folder. You should get the "Authenticate" and "replace" prompts again. Step 4). Close the Kernels folder and scroll to PrelinkedKernels folder and hit arrow tab. Drag the prelnked kernel from the desktop kernel folder to the relinked kernels folder and replace it. Follow the usual prompts. Optional, you can remove the "immutable kernel" or leave it there. If you cannot boot after several attempts you may need to remove nit to help load the new kernel. Step 5). Now the post important part is to run Kext wizard or equivalent Kext repair tool. We need to rebuild caches and repair permissions. Make sure to select the risen disk as the target disk for this. Kext wizard allows you to select a target disk other utilities may not. Step 6). Open Clover boot loader and load onto the Ryzen disk. Be especially careful when loading clover to the drive check the Change Install Disk option and make sure you only load it to the Ryzen drive. After clover is installed open the EFi icon on desktop (disk) and then open the Clover folder. Replace the config.plist and kext folder Other. Check your Drivers64Efi folder for the apfsEFi driver in case you need it. Place it there if needed. Ryzen High sierra Kernels and Kext.zip
[RYZEN] macOS Sierra Post Install - Troubleshooting (NVIDIA & Other Drivers, Audio, Hardware compatibility, etc.)
motoxnate posted a topic in AMDThe is the Post-Install topic following the Ryzen Clover Installation Guide for macOS Sierra. If you have yet to install Sierra on your Ryzen machine, check out that thread for help installing. Here we can discuss post install troubleshooting such as well known issues with NVIDIA Drivers, audio interfaces, etc. Here is one workaround for audio that I am using - My audio was not working and I spent days trying to get it to work (ASUS Prime X370 Pro) to no avail. Eventually I bought this for $10 and it worked immediately with no drivers or setup: https://www.amazon.com/gp/product/B072BMG9TB/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 One question for starters, I am using a Radeon R9 280x with no graphics injection. If I put my Ryzen build to sleep, it changes power states correctly. When Powered back on, the monitors don't turn on. I don't know if this is related to the GPU, or just an issue in general, but in any case I would appreciate any help!
shawnanastasio posted a topic in General DiscussionHi all, After realizing that Clover doesn't work on AMD Ryzen systems and the only solution is to use a closed-source fork, I set out to implement Ryzen support in Clover myself and share the results. The source can be found at https://github.com/shawnanastasio/Clover-Ryzen and I've attached a build to this post. I have confirmed that it boots on my Ryzen 7 1800X system, but I have not tried booting macOS yet. If anybody has a Ryzen hackintosh set up, I'd love to hear if it works for you. To try it out, just replace your current BOOT/BOOTX64.efi and CLOVER/CLOVERX64.efi with the attached build. Feedback is welcome! ============ Update 7/1/17: Add support for fractional multipliers (like 39.5). Link to download. ============ Old Downloads: Update 6/30/17: Fix max/min ratio detection as well as FSB detection. Link to download. Update 6/29/17: Add automatic CPU max/min ratio detection. Should resolve clock speed issues. Link to download. CLOVERX64.efi
