yamete888 Posted December 19, 2014 Share Posted December 19, 2014 Did you set the BIOS as in the guide? Use the Haswell kernel? GUID or MBR format? Apologize for the late reply, just came back from family emergency... Using http://forum.osxlati...-guide/?p=45213 as the reference... Yes, I reset BIOS to default, and enabled AHCI in SATA Yes, I did copy the Haswell patched kernel into the install USB GUID...I have formatted the internal drive to GUID. Used the SSDT generated by "ssdtPRGen.sh -d 0 -p i5-4310U" ran on another system. Using the DSDT from the provided for e7440 in Latitude_E7x40.zip + my SSDT always yielded a black screen. Not sure if it matters, but used the DSDT for e7440 from the Mavericks guide ( and finally saw installer, using -v -f flags...but it crashed not long after that... thanks!

Moderators Jake Lo Posted December 20, 2014 Moderators Share Posted December 20, 2014 Hi , first of all , Thanks Jake Lo . My E7440 is running Mavericks right now !! I only have a little problem..when i plug any headphones don't work.. it is detected in system preferences audio , and silence the internal speakers...but don't sound.

yamete888 Posted December 20, 2014 Share Posted December 20, 2014 boot with -f -v -no-zp Thank you! Finally got the installer, and was able to finalized installation... Still on 10.10, had to copy the Extra dir, and Haswell kernel back onto the OSX installed drive, right after the install. Put the "Bootscreen fix" as outlined in the http://forum.osxlati...-guide/?p=45213 guide...it was in the Extra dir, but finalized it with Kext Wizard into /S/L/E... Got OSX installed, and it boots to the desktop ok, but this is what I have observed, and dunno if it's that is expected... After selecting in Chameleon the boot partition, and seeing the Apple logo & white background, screen goes black for like 28 sec, the oly thing lit is the drive icon, and after that, then screen comes back with the Apple logo/white screen with the status bar in black...then status bar changes right away to white color, and I see some vertical lines at the top of the screen...(see top of 100_2571.JPG image, there are like 8 vertical greenish lines). These lines dissappear when OSX gets to login screen, and desktop. Haven't used the system system to see if any other graphic glitches creep out during regular usage. But overall, looks pretty good! Most of the functionality, is there as pointed out in the guide! BTW, system only has OSX in GUID...created a partition for Linux...(/dev/disk02s4). Reformatted it in gparted as ext4, set that partition flag to boot. Tried installing Ubuntu 14.04, and installed GRUB in disk0s4. I was under the assumption that Chameleon would see it and offer it as an option to boot, but it wasn't the case... Thanks! Link to comment Share on other sites More sharing options...

Administrators Hervé Posted February 13, 2015 Administrators Share Posted February 13, 2015 Did you replace the vanilla kernel by the Haswell-patched version or configure the ASUSCPUPM in Clover to patch the kernel on the fly? Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted July 21, 2015 Moderators Share Posted July 21, 2015 Are you following the Clover guide by Pokenguyen or my Chameleon guide? I see you posted there as well. If Chameleon, boot with -v -f and post your error. Link to comment Share on other sites More sharing options...
