@cmn699:
Hi, i got a Hd 5450 too, nice card for me (making music), i don't need more power and it has no fan. I was having a lot of fun with Clover and Yosemite, no need for graphic-kext-injection the first time, thanks clover!
But now it looks different...
Because i forget soon about the hack-stuff when my system works, i´m out of actual knowledge now, but i really need to update because my music-software (Pro Tools) doesn´t like 10.10.5 since the last update, bad laggy graphics.
i tried to find a solution (Clover-Configurator and SMBIOS imac 18,2) but that gave me this message at boot screen: "This version of Mac OS X is not supported on this platform! Reason: Mac-77F1*.
I was lucky, because i made a backup of 10.10.5 on another hard drive with ccc
and a copy of config.plist with clover-configurator as config1.plist. With help of the boot flag "-no_compat_check" the 10.13 installation just gave me a black screen, but i could boot into my backup, pooh!
Any help would be great, thanks in advance, Marcus
