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!

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.

 

Edit: also i made mi own SSDT ( i have a i5 4200u) , but i see it only up to 2.4 ghz .. is this normal ?

Make sure to download the correct version of the kext from my Mavericks guide under Updates.

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!

Hi

Dear Jake Lo,

 

I have a E7440 and was trying to install Yosemite 10.10.2 with this guide https://osxlatitude.com/index.php?/topic/7478-dell-latitude-yosemite-install-guide/ 

i was going to install Yosemite to the same SSD as Windows is installed (i created a separate partition but in NTFS)

i passed all 28 steps of "Prepare Bootable USB Drive"

i used this bootpack  Latitude_E7x40.zip 6.31MB 222 downloads

but when i restarted, booted from the usb and chosen "Install OS X Yosemite with -v -f flags" the system began to boot but at the end my dell restarted and nothing happened :( when it booted again i see only "invalid partition table!"

Don't know if its something im doing wrong?

 

please help
