Hello, first of all I'm sorry if this kind of thread is not allowed but I'd like to keep a thread of discussion about El Capitan install on the Dell Latitude E6500. If it's not allowed, please lock/delete this thread. OK, let's get to the point. I have managed to boot the installer just fine, however I am not able to proceed with the installer as the installer only shows "Reinstall OS X" and not "Install OS X". As such, this has caused me to not be able to install the OS due to some "eligibility checking" mechanism. I never had this issue when installing Yosemite months ago. Has anyone ran into this problem? How do I fix this? Is it related to the installer that I used or did I do something wrong while making the installer? Thanks a lot and if you have any tips and pointers or anything to discuss about El Capitan for the E6500 please do so here. --- From here on, I will update my progress in this section. 20170319 1950 -- Installer now shows "Install OS X" instead of "Reinstall OS X" after following another guide to setup the USB installer. I will now proceed to with the installation. 20170319 2013 -- Still at "a second remaining". 20170319 2131 -- Finished with everything, including bootloader installation. El Capitan is buttery smooth. It's amazing.

Hello everyone, After the surprisingly huge success with El Capitan, I decided to give Sierra a try. This thread is dedicated to get at least the installer running on the Dell E6500. Thoughts, opinions and discussions are also very welcome. (1) Using dosdude1's Sierra Patch, the installer USB creation was a breeze. Without the patch, the installer won't even try to boot (incompatible Mac). http://dosdude1.com/sierrapatch.html (2) Installer USB loads fine. (3) NVDAStartup causes kernel panic when trying to boot into the installer. nvda_drv=1 nv_disable=1 InjectNvidia=false does not work. I am not sure why but Nvidia still try to load the driver when nv_disable=1 is already present. I will post my DSDT.aml, config.plist and kexts later (still using the same ones from El Capitan). That is all for now. Any pointers and tips are highly encouraged. Thank you.
