Hi. I try to install 10.10.4. I have downloaded the kernel for 10.10.4 (vanilla), also the bootpackage, changed the name of DSDT-off.aml to DSDT.aml, copied the kext files to Extension/SLE and renamed this folder to Extra and copied to the USB boot. Did not try to make any SSDT file as you advised.
After booting on my DELL with -v -f options I get a very early panic, after the processor type gets recognized as i5-3340M, correctly
Kernel is shown as 14.4.0, Mac OS version: not yet set, System model name? MacBookPro9,2
What am I doing wrong???
Thank you for advise
