Dear all, I do have the exact same trouble with mine. Here is where I'm now. I have been able to make OS X recognize a camera using this: https://github.com/RehabMan/OS-X-USB-Inject-All First problem "solved": recognizing the USB device Then, I have not been able to see any image. The softwares (Facetime, Photobooth, Skype...) can see a camera, but there is no image, just a blank black image. By investigating a bit further, I found this opensource project, owned by Intel: https://github.com/IntelRealSense/librealsense This is where I stopped. I have been able to see the webcam image, as well as the 3D sensors images, using the XCode examples of librealsense. But as I don't have any software development skills, I don't know how to go further, maybe developing a plugin based on this lib? Does anyone can help us with this? Thanks all Kalagan

I too have the scrambled graphics on startup. Simply close and reopen the laptop case and you'll be fine. Also, plug/unplug a VGA cable already connected to a device and you'll be fine. It's the way I do with mine, for now.

Dear all, Did Bronxteck's link help you to solve your problem, or did Hervé's advice about SSID work for you? Actually, I just found out, thanks to your topic, that it was possible to change the wifi chip of a Z51. Is it really THAT easy? Or do you guys have any advice or best practices to "physically" do it? For instance, are any of these suitable for our z51-70?: http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Dcomputers&field-keywords=BCM94352Z+ I hope I don't "steal" mixmaster57's topic with my questions, if so, do not hesitate to tell me or to indicate where we can find such info, if specific for Z51-70! Thanks, Kalagan

Thanks for this piece of information. It's still weird to me that the webcam device isn't even present as un unknown device in System Information. Is there anything in the SSDT that could make it visible/invisible? What steps can I follow to further investigate? Thanks in advance!

Thanks Bronxteck, I don't really like your answer, but I understand Does anyone can tell me who did the tests and the validation of the z51-70 with El Capitan??? First, the wired ethernet connection, and now the webcam, both given to be fully compatible with 10.11 by this website, and none of them are working: http://www.osxlatitude.com/edp/compatibility/ EDP team is saying that only tested laptop models are displayed, ant it seems to me that the z51-70 didn't pass the test. Anyone has any info on how the tests are conducted? Thanks Vincent

Dear community, Now that the wired Ethernet connection is working like a charm, thanks to Mieze (http://www.insanelymac.com/forum/topic/287161-new-driver-for-realtek-rtl8111/page-51), I'm struggling with the webcam. It's given to be supported http://www.osxlatitude.com/edp/compatibility/but I can't get it to work. I don't even see anything, neither in the camera, nor in the USB sections of System Information. The same webcam is fully operational under Windows 8. Any idea? Did you also encounter this problem? Thanks in advance, Vincent

The new updated driver is on, and working!

Dear all, I have the exact same problem and we're not the only ones. The developer of the drivers knows the issue with the latest generation of RTL 8111 and will work on it soon: http://www.insanelymac.com/forum/topic/287161-new-driver-for-realtek-rtl8111/?p=2186155

Dear Hervé, Thanks for your advice, I tried what you advised, with no luck. Still the same behaviour. By looking for some more info about the Wifi USB dongle, I found out that the PCI Device ID of the WNA1000Mv2 was 9043, instead of 9041 for the WNA1000M. It should work with rtl8192cu driver (https://usb-ids.gowdy.us/read/UD/0846/9043) but… it doesn't! Grrrr I'm not in luck! If anyone has any piece of idea for my problems, it will be lovely! Vincent

Thanks a lot RiShiE for your advice, I will try to find the Ralink based card you're talking about. Something that I don't understand, and I must admit that I am a lot disappointed with, is that the Z51-70 si given to be compatible with El Capitan, especially for the wired Ethernet connection (http://www.osxlatitude.com/edp/compatibility/). That was the reason why I chose to buy this specific model. I was only expecting to buy an external USB Wifi card. I don't understand who actually tested this model before appearing in the compatibility list, and I'm not even sure it has been tested. Do you guys have info on this "compatibility" list? Do you think wired connection would work if I install Yosemite instead of El Capitan? One last thing, do you also have a "scrumbled" display on startup, that you can "fix" by plugging/unplugging a VGA cable or by closing/opening the laptop lid? If so, did you find something to automatically fix that? Thanks in advance! Vincent

Thanks folks for your answers! As I said, I am using (or trying to use) an external USB Wifi adapter, Netgear WNA1000M, which is in the list of supported products of this driver http://www.hackintoshosx.com/files/file/4587-all-in-one-kext-for-realtek-wireless-usb-adapters-el-capitan-ready/, with no luck. I will try to find the adapter you're talking about from here, in France. Does anyone have any idea for the wired connection? I'm really stuck with this! Thanks in advance, Vincent

Hi everyone! Did anyone manage to get network on the Z51-70? I can't have neither wired, nor wifi (I bought a Netgear WNA1000M). I tried several kexts, from here for the wifi : http://www.hackintoshosx.com/files/file/4587-all-in-one-kext-for-realtek-wireless-usb-adapters-el-capitan-ready/ And from here for the Ethernet wired connection : - https://github.com/RehabMan/OS-X-Realtek-Network/ https://bitbucket.org/RehabMan/os-x-realtek-network/downloads - https://github.com/Mieze/RTL8111_driver_for_OS_X I also tried the one from EDP. No success anytime! I still have a wired connection that detects a cable, but can't get an address from DHCP, and doesn't work with proper manual parameters. The Wifi doesn't even show any piece of life, and the Wifi utility provided with the driver stays stuck at launch. I tried kexts in several places, kexts folders in EFI partition, Extra folder, /S/L/E, and /L/E. I disabled SIP (http://clover-wiki.zetam.org/Configuration/RtVariables#rtvariables_csractiveconfig), rebuilded kext caches hundreds of time, with no success. Did anyone encounter any success with network connection, either wired or Wireless? Free to discuss with all the other Z51-70 owners! Thanks in advance!
