Must be done before upcoming OCLPs. I remembered an important thing: the BIOS must have AVX2 instructions enabled instead of AVX512. Could this be the cause? Check if this is true. To @all: By the way, this applies to all owners of motherboards on the Haswell generation. Enter BIOS: Restart your computer and repeatedly press Del, F2, or F12 (depending on your motherboard manufacturer). Locate CPU Settings: Navigate to the Advanced or OC/Overclocking tab, then select CPU Configuration. AVX Parameters: On some high-end motherboards (e.g., ASUS ROG), look for AVX Related Controlsor AVX Support. Ensure the value is set to Enabled or Auto. Note: Most Haswell-era motherboards do not have a specific toggle for AVX2 because it is considered a permanent feature of the supported instruction set. Key considerations for 2026: Model Support: AVX2 is available on Intel Core (i3, i5, i7) Haswell processors. However, budget models from that era (Pentium and Celeron) physically lack these instructions and they cannot be enabled. Virtualization: If you are using virtual machines (e.g., VirtualBox), AVX2 support must be manually enabled in the specific VM's settings for the guest OS to use it.

Thebes Knossos Posted January 21 Share Posted January 21 The processor have Avx2, not Avx512. This laptop have a very simplified (text mode) Bios, Insyde Corp V1.32, and only a Haswell iGPU. I think beginning with Tahoe 26.1 (or 26.01) it is no more possible to install Tahoe, I've just redone 26.1 net install via recovery and same result. 1 Link to comment https://www.insanelymac.com/forum/topic/362078-release-macos-tahoe-262/page/7/#findComment-2846741 Share on other sites More sharing options...
verdazil Posted January 21 Share Posted January 21 @Thebes Knossos, for recent macOS versions, including macOS Tahoe, AVX2 is critical; AVX-512 is not. AVX2 Effectively required for modern macOS releases (Ventura, Sonoma, Sequoia, Tahoe). Core system frameworks and many bundled binaries are built with the assumption that AVX2 is available. CPUs without AVX2 cannot reliably run recent macOS versions; workarounds, if any, involve heavy patching and reduced stability. AVX-512 Not required to boot or run macOS, including Tahoe. macOS does not rely on AVX-512 at the operating system level. Apple never shipped Intel Macs whose macOS compatibility depends on AVX-512. Lack of AVX-512 has no effect on macOS installation, boot, or normal operation. 4 Link to comment https://www.insanelymac.com/forum/topic/362078-release-macos-tahoe-262/page/7/#findComment-2846744 Share on other sites More sharing options...
vamose Posted January 21 Share Posted January 21 Installation is possible, I have installed 26.2 successfully. its after the login, when the windowserver kicks in I get black screen, only option is to hard reset. use my EFI in previous post, u should be able to install. 1 Link to comment https://www.insanelymac.com/forum/topic/362078-release-macos-tahoe-262/page/7/#findComment-2846745 Share on other sites More sharing options...
vamose Posted January 21 Share Posted January 21 Can some one guide me how to perform the steps below in hackintosh. I do not have bootable recovery.. Fix macOS Tahoe WindowServer crashing with endless loop/reboot To rectify this issue, boot into Recovery, then mount the Data volume on your partition. So, launch Terminal and run rm /Volumes/<Partition Name "Macintosh HD">/Users/<user name>/Library/Preferences/com.apple.Spaces.plist That’s it. These were the steps to fix the macOS Tahoe WindowServer crashing, leading to an endless loop/reboot. As far as the official stance on this matter is concerned, the developers are aware of this issue (153570422), but they haven’t given out any ETA for the rollout of a fix. As and when that happens, we will update this guide accordingly. In the meantime, the aforementioned workarounds are your best bet. 2 Link to comment https://www.insanelymac.com/forum/topic/362078-release-macos-tahoe-262/page/7/#findComment-2846746 Share on other sites More sharing options...
verdazil Posted January 21 Share Posted January 21 @vamose, maybe boot into Recovery mode using a flash drive with the macOS Tahoe installer? 2 Link to comment https://www.insanelymac.com/forum/topic/362078-release-macos-tahoe-262/page/7/#findComment-2846747 Share on other sites More sharing options...

As and when that happens, we will update this guide accordingly. In the meantime, the aforementioned workarounds are your best bet. Method 1: Using your macOS USB Installer (Recommended): Your macOS installation USB acts as a portable "Recovery" partition. This is the safest way to access the terminal. Boot from USB: Plug in the USB drive you used to install macOS Tahoe. Select it in your OpenCore/Clover boot picker. Open Terminal: Once the installer loads (the screen where it asks to "Install macOS Tahoe"), ignore the main window. Go to the top menu bar and select Utilities > Terminal. Identify your Disk: Type the following command to see your disk's exact name: ls /Volumes/ (Look for your main system drive, e.g., "Macintosh HD") Run the Fix: Type the command carefully. Use quotes if your disk or username has spaces: rm -f /Volumes/"Macintosh HD"/Users/"YourUserName"/Library/Preferences/com.apple.Spaces.plist (Replace Macintosh HD and YourUserName with your actual names). Reboot: Type reboot and hit Enter. Method 2: Using Single User Mode (No USB needed) This method allows you to enter a command-line interface before the WindowServer crashes. Boot to Single User: In the OpenCore picker, highlight your Tahoe partition. Press Space to see extra tools/args. If you see a "Single User" option, select it. If not, you may need to add -s to your boot arguments. Mount the Filesystem: Once the text stops scrolling and you see a prompt, type: /sbin/mount -uw / Delete the file: Run the removal command: rm -f /Users/"YourUserName"/Library/Preferences/com.apple.Spaces.plist Reboot: Type reboot and hit Enter.

If you only have integrated Haswell HD 4400 graphics and you're using a laptop where you can't upgrade the graphics card, then Tahoe isn't for you. There's nothing you can do. Tahoe doesn't have drivers for the Haswell HD 4400, nor does it have OCLP, which adds these drivers. The one that works with Tahoe only has patches for modern audio and modern Wi-Fi.

Thebes Knossos Posted January 22 Share Posted January 22 Il y a 10 heures, MakAsrock a déclaré : Si votre ordinateur portable est équipé d'une carte graphique intégrée Haswell HD 4400 et ne permet pas de mettre à niveau cette dernière, Tahoe n'est pas fait pour vous. Il n'y a rien à faire. Tahoe ne prend pas en charge les pilotes pour la Haswell HD 4400, ni OCLP, qui fournit ces pilotes. La version compatible avec Tahoe ne propose que des correctifs pour l'audio et le Wi-Fi modernes. Not sure we will not get OCLP patches for haswell metal grahics and Tahoe, have you any source we don't get it with final 3.0.0 or later ? To prepare this, i need first to install latests Tahoe (or upgrade from version 26.0). 1 Link to comment https://www.insanelymac.com/forum/topic/362078-release-macos-tahoe-262/page/7/#findComment-2846758 Share on other sites More sharing options...

The OCLP developers may be working on this, but in any case, a graphics patch should already exist, and it's missing. I tried to include the OCLP patch (intel_haswell.IntelHaswell,) intended for both Metal and non-Metal GPUs in my build, but Tahoe26.2 refused to launch with it. You also need to be able to run Tahoe26,xx on your hardware, which I highly doubt.

Unable to get Tahoe 26.2 running, so will continue with what is available 26.0.1 I don't know the exact reason and I don't have your equipment. However, I'd assume the issue lies with the named framebuffer for the RX580. My apologies, the Dayton framebuffer was a specific suggestion for certain Polaris rebrands, but it seems it's not compatible with your port layout in Tahoe, causing the VESA mode. To fix this in your config: Change @0,name through @3,name from ATY,Dayton to ATY,Orinoco (the correct named framebuffer for RX 580). Ensure your device-id is 67DF0000 to match native Polaris drivers. Since you are going 'Native' (no WhateverGreen), the -igfxvesa boot argument in your config is doing nothing. It only works when WhateverGreen is present.

First, answer this question: 1 hour ago, MakAsrock said: Ensure your device-id is 67DF0000 to match native Polaris drivers. If it matches, the card should work natively, without a named framebuffer. 2 Link to comment https://www.insanelymac.com/forum/topic/362078-release-macos-tahoe-262/page/7/#findComment-2846780 Share on other sites More sharing options...
