    macOS Catalina 10.15.4 is out

    Released March 24th, 2020.
     
    Watch out folks as this update can be problematic on Sky Lake and later platforms. Update Lilu + WEG kexts to latest available versions and Clover to r5107 before initiating the update. If you cache your kexts from /L/E (or /S/L/E), remember to also update the kexts in the E/C/k/O of your EFI partition as the temporary update partition boots only with kexts injection. Faking a different CPUID should no longer be required but boot parameters -lilubetaall and/or -disablegfxfirmware may be so until the update has fully completed.
     
    I've also noticed that 10.15.4 no longer supports XCPM on my Ivy Bridge laptop (Latitude E6230) so it's back to generated CPU power management SSDT + AICPUPM patch.
     

     

     

     
     
    At the same time Safari 13.1 + Security Update 2020-002 were released for Mojave 10.14.6 and HIgh Sierra 10.13.6.
     
     Warning to all those who run Catalina on officially unsupported graphics platforms (eg: 1st gen Intel HD, Intel HD3000, nVidia Tesla), the patches/tricks previously used to gain OpenGL-only graphics acceleration no longer work in 10.15.4. As such, stick to 10.15.3 for the time being!

    Broadcom BCM4350 Wireless cards

    Good news on the BCM4350 front!
     
      
     
    Further to recent additional findings, BCM4350-based cards such as the DW1820A are now fully supported. Follow our guide, inject the appropriate properties into DSDT or Clover configuration and off you go. No need to patch kexts or anything of the sort. The closest it comes to working OOB... 
     
    Full 802.11ac speed (867Mbps) + BT 4.1 all supported! 
     
    These cards come as a great supplement to existing M.2 supported models such as DW1560 and DW1830.

    macOS Catalina 10.15 is out !

    https://www.apple.com/macos/catalina/
     
    Build is 19A583. It is available off the AppStore for download. Those who run on beta versions through the beta enrolment program should probably 1st revert to default mode before attempting to download as the new macOS version may not be otherwise be offered.
     

     

     

     
    Our 1st few guides have just stared to roll in so we invite everyone to bring in their new contributions.

    • @Jake Lo   Got Bluetooth and Ethernet (Realtek) working with the kexts you shared. Thanks! Didn't clear kextcache the first time.   My battery life seems to be quite a bit shorter than on Linux. Any thoughts on how I can troubleshoot the battery life?
    • I have a question about a HP ProDesk 600G1 SFF. I have it already running smoothly with Mojave (currently updating to Catalina) but I have only one problem. When I reboot or shutdown it causes a panic. It is not visible. It's caused on the end of the shutdown or reboot procedure. While booting in verbose or just after entering the GUI its telling me it was rebooted by a panic. I don't know if it is also resetting the BIOS. I don't think so but I think it has something to do with it. At insalymac there is a elitedesk 800g1 which is almost the same system somebody tells something about a RTCMemoryFixup.kext which had to be added but I tried and no success. Any idea how to fix this?      
    • No nvidia graphics in IOReg, so it's definitely been disabled. You can also check system information under graphics/displays. Power management is enabled and working. You can try disabling SD Card and Com ports in BIOS and anything not used to preserve energy.
    • Thanks a lot! Sleep working ok, keys also   I attach ioregistryexplore dumped file, if you can check if nvidia is disable - because I don't exceed battery remaning time. In coconut battery I have power comsumption still about 15 watts in idle.    Best regards ioregistry_after_clover.zip
    • They are 2 different class of processor.  E5470 is Skylake with HD 520 (newer than E7450) E7450 is Broadwell with HD 5500 All is supported for E7450 (besides wifi - usually comes with Intel which is not supported) E5470 - same as E7450 but SD Card is not supported, finger scanner, wifi if it's intel.
    • try this, replace Config file and add the SSDT* to clover patched folder 5480_Kormoran.zip
    • @Jake Lo i have a question, which one i should buy? E5470 or Dell Latitude E7450?
