    macOS Catalina 10.15.7 is out

    Released September 24th, 2020.
    Build 19H2.
     
    We thought 10.15.6 would be the last major Catalina version with further updates limited to Supplemental Updates or Security Updates only. Today, Apple proved us wrong and released 10.15.7 update today! Safe to install on our Hacks without specific issues or surprises to expect. 
     

     

     

     
     
    Security update 2020-005 for High Sierra (17G14033) and Mojave (18G6032) also released at the same time.

    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.

    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).
