    @dosdude1 I have a question: how about the fan of the CPU? you have now built a T9900 processors, the fan runs more often because of the stronger heating of the CPU? and how high is the CPU temperature during normal operation?

    Surprisingly, it seems to run no warmer than it did with the original CPU installed. The fan doesn't even get up to full speed when running Geekbench, so I'd say it runs quite well.

    That is only a 35W TDP part which is nothing compared to the 45W TDP toaster that they used in the 2006 MacBook Pros.

    Does anyone think there will ever be graphics acceleration for the 2011 iMac? I have 28 of these at a media college that i'd love to keep going with updates if possible. I've already used the patcher on our remaining 2008 and 2009 iMacs, and they are like new, so really appreciate the work done so far! We're too poor to buy new machines at this point so things like this are a godsend!

    So,
    Firstly, Happy New year everybody!

    I was hoping if somebody could help with an issue.

    I am running Mojave 10.14.2 (SSD) on MacBook Pro 2011(Late) i7 756GB

    I just replaced the Bluetooth/Airport card to BCM94331PCIEBT4CAX and lost Bluetooth on Mojave completely.
    However, If I boot into the High Sierra Partition (As a failsafe on HD), Bluetooth is recognized.

    Can somebody help with this, please?
    :)

    Would i have to rerun the dosdude patcher using a install disk ?

    It seems as Schwab on previous page 456 reported a succesful upgrade of a 2011 iMac using ResXtreme to correct graphics problems with colors. However not clear status on the possible missing graphics acceleration.

    Hi Varad and happy new year to you. There have been quite few members who have had troubles with Mojave and bluetooth. The problem appears quite random and there has been no definite identification of the exact problem. However, it does seem more prevalent in those who have updated their BT/Airport card. As you know the card works well in HS then there is a chance replacing some kexts in Mojave's S/L/E with those from your HS partition. This is what worked for me. First try IOBluetoothFamily.kext and IOBluetoothHIDDriver.kext. Remember to fix permissions after and clear the kext cache. This has worked for quite a few members and got me working on 14.0. However, to get BT working on 14.1 and 14.2 I had also to replace IOACPIFamily.kext. Take it in stages and you may get lucky!

    SwitchResX does the same trick, reduce color depth and the partly-inverse colors are correct on all ATI cards (even eGPUs). Acceleration is still missing, though.

    After replacing the kext with those from HS (try both the bluetooth ones first) open Terminal and run the following commands. You can copy and paste them into terminal:

    sudo chmod -R 755 /System/Library/Extensions/IOBluetoothFamily.kext

    sudo chmod -R 755 /System/Library/Extensions/IOBluetoothHIDDriver.kext

    sudo chown -R 0:0 /System/Library/Extensions/IOBluetoothFamily.kext

    sudo chown -R 0:0 /System/Library/Extensions/IOBluetoothHIDDriver.kext

    then clear the kext cache using this:

    sudo kextcache -system-prelinked-kernel

    Let the final command take its time. You will get a lot a text referring to the cache. Make sure it is finished before you reboot your system. With a bit of luck you may have your BT up and running. If not you can try replacing the IOACPIFamily.kext as well:

    sudo chmod -R 755 /System/Library/Extensions/IOACPIFamily.kext
    sudo chown -R 0:0 /System/Library/Extensions/IOACPIFamily.kext

    sudo kextcache -system-prelinked-kernel

    So I tried the what @Flacko said, and that didnot work for me because I used old HS Kexts ,
    Later I tried the kexts from the installer USB and they didn't work either.

    What worked was using the 2 Kexts from @jackluke 's post and using the exact commands.

    Hurray !

    Thanks @jackluke & @Flacko !! :)

    Assuming that you are still on Sierra or earlier, when you install High Sierra as a supported machine, the process will convert the system HFS volume to APFS with the normally populated container.

    Successfully upgraded to the latest beta using OTA and macOS Patch Updater 1.2.3

    Screen Shot 2019-01-07 at 2.45.07 PM.png

    Also using HyBrid v1.4 for UI fixes/enhancements.
    Will continue to test this beta. So far so good.

    Many Thanks to @dosdude1 and @pkouame for your tools/apps and to other contributors mentioned on the OP as well.

    EDIT: Correction on the Hybrid version --- used 1.4.1.

    How about the transparency, again the 2 Frameworks files have to be
    replaced or are those of the Beta2 still? I mean these 2 dates:
    CoreUI Hybrid-18C54-v1.4.1 and HIToolboxHybrid-18C54

    Yes, I replaced those with the ones from 1.4.1 version. Verified the checksums:

    52eede43e030fd75a37e61fc7205cddc0884d344 CoreUIHybrid-18C54-v1.4.1

    So far, no luck with the El Cap kexts. I think I´ll have to dive deeper and replace single kext contents. I found that actually, the MB 4,1 runs El Cap only without USB functionality also - but fine with Yosemite. (At least when I run El Cap on it from a MB Pro 3,1 over firewire target mode). Have not tried original vanilla installation from another machine so far., might behave different, though.
    Screenshot shows the kexts on Mojave and Yosemite that we have to deal with (I assume). Note that IOUSB... are not all present (5x) on 10.10.5 ?!

    Don't know if there's a solution for this, but I followed the steps here and installed Mac OS Mojave on my 2011 Macbook Pro, but now whenever I sleep it the fans stay on and if I try turning it on, I can't, I have to hold the power button till it shuts off then I can power it on, any solution? Thanks.

    Short note to @dosdude1 : The backlight brightness patch for old MB Pro 4,1 (CCFL backlight) still works with the latest 10.14.3 beta 3. Perhaps it could be integrated into a (hopefully!) coming v1.2.4 of your post-patch list?

    Well done, I was just about to send you the kexts. You will have to go through this again if you update to 14.3 when it is available as the replaced kexts will be overridden. Keep a back up copy of the kexts that work.

    Hi, are there any known issues reverting back to High Sierra? I've gone back to High Sierra (format and fresh install from USB stick as well as restoring a backup. Since then I've noticed there is a 30 second black screen delay right before the system log in screen should show. After this 30 second delay everything works fine. Any idea if this could be related? I'm no 100% positive when it started happening.

    EDIT: Never mind, the issue was something else.
