    Hey guys,
    Recently updated to Sierra, slowed the machine way down, followed all recommendations, including clean install, still terrible. Internet speeds went from 200 down to 20. Went back to El Capitan, internet speed still horrible so I put in a new ethernet card which cured the internet problem. Overall, better than Sierra, but still not nearly as snappy as it used to be. Now, about every second reboot I get the crazy screen I've attached. I don't know what it means, if anyone does, I'd greatly appreciate the help.
    3.33 6 core, 5,1, 2013.
    250gb ssd boot,
    3tb hd,
    1 tb hd,
    kernal.jpg macgtx680 card.

    Thanks!
    David

    It looks like a problem with a Broadcom network adapter. Do you have anything unusual installed related to networking?

    Ethernet cable running from first floor cable modem to a splitter on the second floor, then from splitter to my Mac. I have two wireless routers, one from cable company and my Apple router, but that's only for wireless.

    Maybe the broadcom is my new ethernet card, but that seems to be functioning fine. Screen Shot 2017-06-30 at 7.24.16 PM.png

    My knowledge on the topic is very low, so this is just guesswork on my part.

    The kernel message looks like it is complaining about AppleBCM5701Ethernet.kext, and your new card uses AppleBCM5701Ethernet.kext. The new card is almost certainly causing the message.

    What do you mean by "splitter"? A network switch?

    Do you get better Internet speed if you plug in directly to the Cable Modem instead of through all the other devices?

    Sorry, yes, gigabit switch so my son can share the network. Network speed isn't an issue anymore, back up to 200 down. The real issue is the laggy machine now, everything is like a half to one second behind in typing etc. I thought maybe the error messages would have something relevant to my lag since I can't find any other solution.

    A lot of things can cause lag. If you have a spare drive, install MacOS clean on it and see if the lag persists. If it does persist, then you likely have a hardware problem. If it goes away, then it is a problem with something in your software or configuration settings.

    Also, try a wired keyboard and mouse to see if there is still lag.

    Thanks, will do, I am on a wired keyboard and mouse, so, that's ruled out.

    Ok, tried MacOS clean on a different drive, and this machine is still laggy, driving me nuts. Any other ideas?

    Thanks

    That rules out software. I'd start pulling optional hardware once piece at a time and checking for lag. I'd start with the Ethernet card--it is the obvious contender since it is throwing Kernel Panics.

    Or you can do what the service manual recommends, which is the opposite direction--remove all hardware down to the bare minimum, test for the problem, and then add back one piece at a time, testing after every piece is added.
