    If any of you are running a GTX 980 and on El Capitan, the new Public Beta 5 breaks the compatibility. Seems to be something wrong with the nVidia driver. It threw my system into a reboot loop no matter what, and only way I could get back up was to boot into Boot Camp.

    Are you sure you had the driver re-selected after the update?

    After every OS update you may need to reinstall the Beta Web Driver if the NVSTartup kext got replaced.

    Yep. I reinstalled the GT120 and made sure it was enabled, put the 980 back in, boot loop. Then I reinstalled the nVidia web driver, made sure it was enabled, put the 980 back in, boot loop. Card works fine in Windows 10 boot camp. Something is definitely up with this new 10.11 update.

    Updated with the Apple card and native drivers. Everything good. Waiting for the driver.

    Then count on Nvidia to release a fix shortly

    I trust you. I was hoping it would work but compatibility had to break at some point while the graphics subsystem is being developed.

    I decided to be safe and play by Apple's rules before I damage something. No PC graphics card and no Windows 10 installation until it is safe to do so. I'll wait for the web driver for the final release version of El Cap. I'll wait until Windows 10 has a more mature build. Until then I'll concentrate on work.

    Preference pane is crashing if I start the NVIDIA Driver Manager. Any idea how to change back to Apples drivers? Thanks.

    ^^^^What I did, was to restart and hold option key and chose my Yosemite startup disk. I then reinstalled the first beta of El Cap from the Applications folder on my El Cap startup disk. I reinstalled it, when I reached the desktop I turned off the Nvidia Web Driver and reinstalled DP5. It took some time, but I'm back up and running El Cap.

    Guys, a PRAM reset will turn off the Web Driver on next boot.

    I was installing PB5 when I saw this thread made. When the installer shut down the computer I switched graphics cards and reset the PRAM. Hen booted up. The computer booted twice to finish the installer. I thought nothing of it. Then I booted into PB5 and thought everything was a bit slow like it was running on a HDD...it was! I found out that PB5 updated my SSD and my back up on HDD, probably because of the graphics card swap and reset.

    Just as I become more serious about picking up a 980 Ti, this kind of thing is not what I need.

    I was hoping the situation would become more stable over time, but there still seems to be quite a bit of petting required...

    I guess I'd just need to hold off on updates for 2-3 weeks when they arrive... 980 Ti is starting to look good to me with newest web drivers. Hmmm.

    It's hugely, disappointingly frustrating. Any time there's an update your system can completely break for no reason at all. Too bad I really love OS X to put up with this ridiculous ****.

    Edit: before someone says "lolz it's a beta noob", even a random so called mandatory security update can break the video drivers just for fun on a shipping version of OS X

    ^^^^Beta Web Driver b07 does indeed fix the issue. Thanks Asgorath!

    This is Beta software, and this stuff is bound to happen, it's the nature of the beast. I've been a beta site for many years now, used to do a lot of it when I was younger and working part time for Apple. In years past things were a lot worse. I'm impressed with El Cap, and with Nvidia and their ability to turn things around as fast as they do, and for supporting us, a dying breed of Apple user.

    Zorn, if this upsets you, you really shouldn't be using Beta Releases of software or hardware that is not Apple approved.

    Right, let's keep things in perspective: NVIDIA is releasing drivers for a beta OS to enable unsupported GPU architectures with a pretty quick turnaround time. What's your alternative if you want a modern GPU? I don't think there is one. The Maxwell cards are not officially supported, but NVIDIA sure is going out of their way to make them work as well as they can.

    PS - I'd bet that NVIDIA didn't know that the new build would break the b06 driver until it was released, this is a great example of why their web drivers are usually tied to specific OS versions so that they don't get hit by these kinds of binary incompatibility issues.

    Right, as I mentioned above, this isn't a beta thing. The drivers break just for security updates that install in the background, as happened a couple months ago, and from what I hear, just happened again for Yosemite. I'm totally fine with it if this ONLY happens on a beta OS.

    Apple updates 3 major OS versions (10.8, 10.9, 10.10). NVIDIA has a driver out within 24 hours for the most recent OS (10.10.5), and within a couple of days for the other two (most likely delayed due to the weekend). If you're on the most recent OS, you can simply wait a day until the new driver is available. What's the problem here exactly? NVIDIA has a great track record for getting new drivers out within what I'd consider a very reasonable amount of time. It's entirely possible that Apple isn't telling NVIDIA ahead of time, so they may be finding out about these security updates when you do.

    Such a quick follow up release from NVIDIA is actually really great.
