LoBlanc Posted February 20 Share Posted February 20 Hi deeveedee, Not sure if this is the proper place to post my question but how do you get your intel wifi working? I've been trying for weeks without success. Please explain it to me. Thank you for your time 1 Link to comment https://www.insanelymac.com/forum/topic/362386-pre-release-macos-tahoe-264/page/3/#findComment-2847581 Share on other sites More sharing options...
deeveedee Posted February 20 Share Posted February 20 (edited) @LoBlanc I can't take credit for intel Wi-Fi since I have just followed what others have recommended. Here are the steps that I followed: Inject itlwm.kext 2.3.0 via your boot loader (e.g., Kernel > Add ...) Install Heliport 1.5.0 in Applications System Settings > General > Open at Login: add Heliport (thank you @Matgen84 for this tip) System Settings > Wi-Fi: Off (itlwm does not use macOS Wi-Fi framework) System Settings > Menu Bar > Wi-Fi: Off (don't show Wi-Fi in Menu Bar since itlwm doesn't use macOS Wi-Fi framework) Intel Wi-Fi will start after you login.

MaLd0n Posted February 21 Share Posted February 21 Rosetta Deprecations As announced at WWDC in 2025, macOS Tahoe 26 is the last release to support Intel based Macs. Additionally, Rosetta support for apps will end after macOS 27. Starting in macOS Tahoe 26.4, users will be notified when they launch apps that use Rosetta of the upcoming incompatibility. During the beta period, the cadence of notifications will be accelerated, enabling Apple and developers to address any issues that might occur. There will continue to be support for older, unmaintained gaming titles leveraging Rosetta along with software running Intel binaries in Linux VMs. Organizations using a device management service can control the notification experience with the allowRosettaUsageAwareness key.

Hello Download and install the KDK (Kernel Development Kit) is mandatory to use MyKext Installer, if I remember correctly. Just my opinion, at this time, I don't think that the appropriate KDK exists for 26.4 Beta. 2 Link to comment https://www.insanelymac.com/forum/topic/362386-pre-release-macos-tahoe-264/page/3/#findComment-2847612 Share on other sites More sharing options...

arsradu Posted February 21 Share Posted February 21 (edited) So, right now, I can't boot. :)) The joys of using a hack. :)) Sometimes that's bound to happen, especially when using a Beta version. But I knew that when pressing the "Update" button, and already have a few workarounds for it. So that's ok. Right now, it looks like it's not even trying to boot the system. I get the Apple logo for a second, empty loading bar underneath, and force reboot immediately after. :)) So....yeah, looks like KDK support is necessary for 26.4, so even though the update itself goes smoothly, OCLP patches don't work at the moment. And some of my partitions give me an error for HFS+. But no problem, it's not the main machine, everything works fine with Sequoia. And for this one, I'll just revert to last sealed snapshot and that's it. Update: looks like it's only the AppleHDA patch that doesn't work. The WiFi patch works fine. So...if you don't mind this, and the HFS+ thing, you can still apply root patches with OCLP-Mod. Just make sure to disable AppleHDA patches first.

You might be able to boot and get Wi-Fi. I can't promise more, but be careful: 1. Insert the boot argument amfi=0x80 2. Disable the Modern Audio patch for AppleHDA restoration in settings. 1 1 Link to comment https://www.insanelymac.com/forum/topic/362386-pre-release-macos-tahoe-264/page/3/#findComment-2847629 Share on other sites More sharing options...

Matgen84 Posted February 22 Share Posted February 22 @carlo_67 @maly70 there is a warning on OCLP-Mod about that. For 26.4B1 @laobamac_yyds tells to wait for new KDK from Apple.

deeveedee Posted February 24 Share Posted February 24 Easy update to macOS Tahoe 26.4 Beta (25E5218f). Still using VoodooHDA.kext 3.0.3 for audio and I'm not using Wi-Fi on this hack, so no root patches. SIP csr-active-config = <01000000> for VoodooHDA.kext. Using Lilu.kext 1.7.2 (Beta) with WhateverGreen.kext 1.7.0 (Release) for smooth macOS update without disabling Polaris dGPU Temporarily disabled BluetoolFixup.kext for incremental update Spoiler HFS+ is fixed with this Beta update (was there ever any doubt? :)) 9 Link to comment https://www.insanelymac.com/forum/topic/362386-pre-release-macos-tahoe-264/page/3/#findComment-2847706 Share on other sites More sharing options...
