pianoguy Posted February 13, 2015 Share Posted February 13, 2015 Hey guys, after spending several days with trial and error, I figured out how to update to 10.9.5. It runs perfect! Check out my video (the first half is about installing 10.9.0 on AMD PC, but you can fast forward to the part about updating to 10.9.5) Link to comment Share on other sites More sharing options...
DONNYTEN Posted March 5, 2015 Share Posted March 5, 2015 Hi. Thanks for the video. I got to the part where I have do the DITTO commands, but I'm getting "system extension cannot be used. The system extension "/system/library/extensions/System.kext" was installed improperly and cannot be used. Please try reinstalling it or contact the products vendor for an update" then the same error repeats itself for each of the kext files. was installed improperly and cannot be used. Please try reinstalling it or contact the products vendor for an update". I even tried replacing them manually and got the same error. Do you have any suggestions?

crashtheface Posted March 5, 2015 Share Posted March 5, 2015 this guide is wonderful. thanks so much for this. currently running flawless 10.9.5 with nvidia web drivers on the following hardware: AMD FX 8350 Black Ddition @ 4.6ghz Asus Crosshair V Formula Z Vengeance DDR3 @ 2133mhz @ 16gb 4x4 OWC 120gb SSD 2x EVGA GTX680 2GB anyone for that matter? you can just ignore this and continue with the post update kext installations, after you configure permissions with kext wizard and replace the mach_kernel with the file renamed "amd" you should be good to reboot; follow OP's directions to the T and ignore the "kext cannot be used" warnings, they will absolve when fixing permissions/restarting.

DONNYTEN Posted March 5, 2015 Share Posted March 5, 2015 so ( from memory), install update, don't restart, rename to amd, place in root, drag system kext from downloaded folder to kext wizard, install, then repair permissions, then restart, and -x -f, Open terminal, do the ditto stuff and ignore all the errors I get? should i repair permissions after they are replaced as well? I'm going to try that and report back..
