Moderators Jake Lo Posted April 28, 2015 Moderators Share Posted April 28, 2015 If you already have Mavericks installed, you can use the same bootpack for Yosemite. See my guide for Yosemite in my signature below. Post your files and I'll let you know what can be updated and/or leave out for Yosemite. 1 Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted May 1, 2015 Moderators Share Posted May 1, 2015 Please upload your /Extra folder from Mavericks when it's working. Try booting with -v -f and post the error. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted May 4, 2015 Moderators Share Posted May 4, 2015 What files do you have in /Extra/Extensions? Do you have patched AppleHDA or voodoohda installed? Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted May 6, 2015 Moderators Share Posted May 6, 2015 Remove AppleACPIPlatform, you should get sound. I see you have a patched AppleHDA already. Do you have a DSDT? If not, try this one here. Link to comment Share on other sites More sharing options...
