Hi guys,
Something not good happened with my Optiplex 990.
From AppStore I pressed “Install“ button for Sierra (I wanted to have it downloaded in Application folder, and exit from installation and make USB flash). So I pressed Install button and went for smoking. When I back (maybe 5 mins) I sow that PC was rebooting. After that I can not load any version MAC OS. I have on my HDD installed 10.9, 10.10 and 10.11 (and 3 installation for all versions. I put HHD to rack, created 7 partitions first for clover, three partition with installations of 10.9, 10.10, 10.11 and tree partitions where each MAC OS was installed. And everything worked perfectly. I was able to load any version of MAC OS). How ever after last restart that I mentioned I can not load any MOC OX installed, and can not load any installation. The same when I try to load installation from USB (I have 2 that I used before. Also I created new. Result is the same). I’ve load default BIOS setting – it did not help. Then I fleshed BIOS (I already had A19 and flash A19 again) – it did not help. I have UEFI mode in BIOS.
When I load 10.9 or 10.10 I can see on the screen:
OsxAptioFixDrv: Starting overrides for .IABootFiles\boot.efi
Using reloc block: yes, hibernate wake: no
Efiboot loaded from device: Acpi(PNP0A03,0)/Pci(1D10)/VenMedia (<UUID here>)
/HD(Part2,Sig00000000)
boot file path: .IABootFiles\boot.efi
…………………
root device uuid is ‘<UUID here>‘
When I load 10.11 I can see on the screen
OsxAptioFixDrv: Starting overrides for .IABootFiles\boot.efi
Using reloc block: yes, hibernate wake: no
However from another HDD I can Windows 7 without any problems.
Looks like something broken inside BIOS wich is MAC OS specific.
Will dig in deep this weekend.
P.S. During these experiments used 3 versions of CLOVER.
P.S.S. i5-2400, 1x8GB, 2xHD6350 (interval video is disabled in BIOS).
