    Need Help to replace stock Apple kext from /L/E in BigSur

    Oh sure, if even. It seems that any kexts not already present in the boot snapshot's prelinked kernel cache will load just fine even when not passing validation so long as SIP is disabled. However, it seems that for Big Sur, injecting a kext that attempts to replace a kext already present in...

    Need Help to replace stock Apple kext from /L/E in BigSur

    Can someone tell me if it is possible to get a replacement kext into the prelinked kernel cache under Big Sur ? I am running 11.6.1 with OpenCore 0.7.7 and would like to replace the stock Apple IO80211Family.kext with my own modified version which sits in /L/E. Injection no longer works...

    [Guide] Intel Framebuffer patching using WhateverGreen

    With the 10.14.5 Mojave update, I am now experiencing VERY slow wakes from sleep, usually 10+ minutes, often no wake at all. I'll push the power button to wake up and the LED will come on solid but the display will remain sleeping for at least 10 more minutes. Everything was working perfectly...

    Mojave freezes after opening App Store application

    OK, I had exactly this problem on a couple of Lenovo ThinkCentre tiny form factor desktops. Both are Haswells. One is an M73 with Intel Core i3-4130T CPU @ 2.90GHz and the other is a M93p with Intel i5-4590T CPU @ 2.00GHz. Immediately after the Mojave 10.14.4 update both systems would freeze...

    [Guide] Sierra 12.6 on Thinkpad T430 Almost Perfect!

    I doubt that your problem has anything to do with those ACPI errors as they involve battery status and I was booting up just fine with those same exact errors. I've since upgraded my T430 to High Sierra. Your current hurdle is definitely a USB thing. For starters, make sure that your installer...

    [solved] Sierra Toshiba SandyBridge Reboot in Sleep and Shutdown

    Roger that. I've had ALXEthernet.kext crash me out on a couple of other Sierra/High Sierra builds since. Looks like ALXEthernet.kext is a dead kext now going forward unless somebody is gonna step up and fix it. But probably nobody will bother with the new Atheros2200Ethernet.kext doing the job...

    [Guide] Sierra 12.6 on Thinkpad T430 Almost Perfect!

    Ah ! Nice. And, of course, I had your laptop config collection the whole time, lol After all, your work is an absolutely required reference for any hack :) Just didn't look closely enough in the right place. So like me. But, no regrets. This exercise helped expand my understanding. And...

    [Guide] Sierra 12.6 on Thinkpad T430 Almost Perfect!

    OK cool, Solved this one myself. Turns out that only a simple patch to AppleIntelFramebufferCapri.kext is needed. Since my internal display was fine with ig-platform 0x01660004, I simply needed to modify the internal (LVDS) framebuffer for ig-platform 0x01660003 to match it. A hex search of...

    [Guide] Sierra 12.6 on Thinkpad T430 Almost Perfect!

    Hey hey ! Nice guide & nice work. This really made the Sierra 10.12.6 install a breeze but just one problem. Looks like the external DP should be working but mine is dead if I go with the suggested ig-platform. In fact, with 0x01660004 there is only one framebuffer @0, so no external display...

    [solved] Sierra Toshiba SandyBridge Reboot in Sleep and Shutdown

    Fair enough. I don't have any problem installing Apple system updates or any other types of updates for that matter. Didn't even realize kexts/Other had anything to do with that. I had versions of my DSDT both with PNOT references commented out and not commented out. I noticed no difference...

    [solved] Sierra Toshiba SandyBridge Reboot in Sleep and Shutdown

    My Clover folder & config.plist ? I do practically nothing in there other than load my own SSDT, suppress the 10.12 initial boot glitch and patch for HDMI audio. It's pretty bare bones. I don't think that I even inject video. All of my mods are done in the DSDT. I'm a retired programmer so I...

    [solved] Sierra Toshiba SandyBridge Reboot in Sleep and Shutdown

    as per the developer's FAQ ... FAQ Could you add support for AR813x and AR815x? Sorry, no, because I used a different linux driver as the code base than Shailua which doesn't support these chips so that it would be too much work to add support for them. ----- No worries, this old Toshiba...

    [solved] Sierra Toshiba SandyBridge Reboot in Sleep and Shutdown

    Hmmm, seems this thread might have been marked as solved just a bit prematurely but, as it happens, I did indeed find the culprit. I do appreciate your confidence in me :)) It turns out that my problem was entirely caused by the LAN/ethernet kext ! This old Toshiba L755 laptop has the...

    [solved] Sierra Toshiba SandyBridge Reboot in Sleep and Shutdown

    Ah, u always tell me something like that and then I stumble onto a relatively simple fix that gets it all going. Oftentimes it's from a solution you, yourself posted, in response to a query something like one of mine, lol ! I continue to applaud your contributions to the community, though for...

    [solved] Sierra Toshiba SandyBridge Reboot in Sleep and Shutdown

    Updating an older Toshiba SandyBridge laptop. This is a simple Intel HD3000 version of the Toshiba L755 not the one with the dedicated NVidia GPU. It had been running Mountain Lion flawlessly for a long time. I now have Sierra 10.12.6 loaded and most everything looks really good: SpeedStep...
