Dell inspiron 5458 HD 6000 El Capitan


Recommended Posts

My laptop is Dell inspiron 5458, i5 5250u, intel hd 6000.

I have changed DVMT to 96MB (setup_var 0x15b 0x3) but in Windows 10 it still 128MB.

And I have created an USB install el capitan (E7450 guide) but I can not boot to install. I have done ""Boot Mac OS X in verbose mode", 4s later, my laptop restart and boot to Windows 10.

Do you help me?

You could ignore what it shows in Windows, as long as it's shows 96MB in the BIOS. Make sure both 0x15b and 0x15c are 0x3 if it applies.

Leave out the DSDT/SSDT. Boot to Clover, hit F4 to export the RAW DSDT/SSDT. Send me /EFI/Clover/ACPI/Origin compressed.


Boot without cache, hit the spacebar when you see Clover, select no cache mode from the drop down.
