    macOS Catalina 10.15.6 is out

    Released July 15th, 2020.
    Build 19G73.
     
    This is most probably the last major update for Catalina with only Supplemental Updates or Security Updates to follow. Safe to install on our Hacks without specific issues or surprises to expect. Blessing issue remains for those of us who experience it since 10.15.5 and this requires a reset of NVRAM to avoid. Failing that, 10.16.5 still installs Ok but the temp update partition remains until the macOS Install Data folder located in /System/Volumes/Data is manually deleted.
     

     

     

     
    Security updates 2020-004 for High Sierra (17G14019) and Mojave (18G6020) released at the same time.
     

    macOS Catalina 10.15.5 is out

    Released May 26th, 2020.
    Build 19F96.
     
    Seems safe to install on our Hacks. Ended up with a macOS could not be installed on your computer error message on the Latitude E6230 and 7490 laptops due to bless tool being unable to set the boot disk. But these are like false alarms because the Catalina partitions of those Hacks remained bootable and were properly updated to 10.15.5. The macOS Install Data folders in /System/Volumes/Data, however, had to be manually removed to get rid of the temp partition so, clearly indicative of a minor problem in fully completing the update at the end of the process.
     
    As for 10.15.4, refresh Lilu + WEG kexts and Clover to latest available versions (v1.4.4, v1.3.9 and r5118 at time of writing) before initiating the macOS 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 folder of your EFI partition as the temporary update partition boots only with kexts injection.
     
    Security Update 2020-003 for High Sierra 10.13.6 and Mojave 10.14.6 released too (build 17G13033 and 18G5053).

    10.15.5 Supplemental Update released today. Build 19F101.
     

    macOS Catalina 10.15.4 is out

    Released March 24th, 2020.
     
    Watch out folks as this update can be problematic on Skylake 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!

    Unsurprisingly, Apple issue a 10.15.4 Supplemental update today. This brings 10.15.4 to Build 19E287. Looks safe to install on all systems running Clover r5107. Had trouble on Latitude E6230 running with Clover r5108 (and reverted to r5107).

    • Ok, I can confirm after typing exactly as mentioned works perfect Many thanks,
    • No, Jake gave you the correct values to reflect your Skylake iGPU rather than the Kabylake iGPU of the OP. Use them.
    • The ig-platform-id didn't really match with what you said. The SMBIOS seems to have changed properly. But the graphics are only in VESA mode.   I'm using OpenCore Configurator and the settings I had under DeviceProperties were,   AAPL,ig-platform-id - DATA - 09001659  device-id - DATA - 16590000   I changed to,   AAPL,ig-platform-id - DATA - 09001619  device-id - DATA - 16190000   Is it correct?    
    • You need to change the ig-platform-id to HD520 instead of using the default for HD620; change 00001B59  to 00001B19, and deviceID from 16590000 to 16190000  and SMBIOS from MBP14,1 to MBP13,1.  
    • Yes, that's correct. Some cloning software might not clone the EFI partition, so just install Clover and copy the EFI folder over.
    • @Hervé , Good to know! Thanks, i'm going to look more into that more.   I have one question still. If one were going to clone a drive to be connected eventually to a separate Apple ID / ICloud Account than the drive that i'm cloning;   1.  Is giving the computers unique Serial Number, SmUUID, MBSerialNumber the only thing i would have to do? Pretty much the steps required for iMessage. (Assuming both of the drives are going to be used on the same hardware obviously.)   2. And the SSDT would be the only thing one would have to switch, if they were switching to a different processor (same laptop or hardware otherwise)
    • Hi,   I’ve used this EFI folder to perform Big Sur Beta 11 installation and seems to be almost perfect. I notice a bit more slowness compared to Catalina. Could be because it’s Beta or either there is some issue because I experience very slow boot. Also important to refer I have HD 520 instead of HD 620.    Thanks in advance,
