HenryV Posted September 11, 2019 Share Posted September 11, 2019 HP 250 G5/Skylake/I5/520 graphics/sunrise point Insyde H20 updated with TPM, virtualizaton and secure boot disabled. 19A546d USB boots -v cpus=1 and begins install ok. After first reboot installer hangs at 14 minutes remaining with high CPU/fan use and no HDD write activity. Same after 4-5 hours. First reboot apparently creates the volume group and writes the installer files to the Data volume ok. Clover shows preboot/installer installer and Recovery icons. It appears that there are no system files being written to the System volume. The reboot USB verbose output screen indicates 'assertion failed 19A546d'. Mojave boots/runs ok on its own partition same HDD. Anyone with similar installer issue on HP notebook and/or Insyde BIOS? Any help appreciated.

HenryV Posted January 10, 2020 Author Share Posted January 10, 2020 This issue was initially caused by a misconfigured config.pilst and subsequently compounded by a low or out of RAM issue. For 10.15.2 combo update there is a rebuild of the dyld cache near the end of the install that consumes more than 2 gigs of RAM. If your system only has 4 gigs and the nvram.plist in clover is set to <string>vm_compressor=2</string> and swap is disabled then the install may hang or take a very long time to complete. Disabling vm_compressor=2 mode in clover options is not sufficient. It must be modified in the nvram.plist. To enable swap from terminal: sudo launchctl load -wF /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist verify/modify clover nvram.plist: <string>vm_compressor=4</string> Link to comment Share on other sites More sharing options...
