Latitude e7440 Installer Boot loop


aeroz51

Recommended Posts

I was able to install Mavericks using this guide: https://osxlatitude.com/index.php?/topic/6472-dell-latitude-e7240e7440-with-mavericks-1095-updated/ 

Installed fine. Boots from HDD as well - only thing is that it scrolls thru about a dozen scripts before prompting login screen.  Also, my wifi does not work - I have an internal Intel wifi card.

It takes me to the boot loader, I press enter on my HDD to boot into Mavericks - not using -v -f   It goes directly into the scrolling pages of text.  Just noticed that sound is not working either.  Thanks for the link to wireless cards.

check org.chameleon.boot.plist to see if the flags are there, remove if it's there.

For audio, make sure you got the latest version of the kext from the updates below the guide. You must install it to /System/Library/Extensions to work. Use kextwizard.
