    Here is some more info about Spectre and Meltdown and how it works in Safari / Webkit and how the fix works too, from the webkit team

    My AV had been blocking com.apple/webkit access on each startup of safari for a short while.
    Sent inquiry to AV support to ask what this might be.
    Replies were vague, in fact i would say they had no idea and finally suggested reinstall OS.
    Just interested if anyone else had this, is it related etc.

      I don’t think anyone runs antivirus software on a Mac because they don’t have the vulnerabilities Windows machines do. Rather than reinstall your OS, I suggest you turn off your AV. No, really, that’s what you should do.

      Antivirus software on the Mac is unnecessary, the Mac does not get viruses like Windows does. The big problems that come to the Mac are warded off by Apple. The remaining shams to look out for typically only impact the web browser like Safari or Chrome by hijacking it with garbage extensions and other stuff that may try to sniff web data.

      For example I recently fixed a relatives Mac that they thought had a virus, but it was just a garbage extension that had weaseled itself into Chrome by trying to get updates to Flash Player from a source other than Adobe – probably from one of those shady pop-ups you sometimes see. Remember that Chrome already has flash installed by default, so this is just garbage in the first place. Never install software from anyone other than the developer or a place like the App Store, and you can avoid that kind of thing.

      If you don’t visit shady websites and download or install shady stuff, don’t torrent, don’t install junk, don’t participate in the dubious web, etc, you really don’t need a Mac Antivirus app at all, it will slow down your Mac and there is not much to protect you from that Apple does not already cover or common sense would ward off.

    Does anyone know if there will be kernel security updates for El Capitan concerning Spectre and Meltdown?
    Because the problem is not just about the browser.

        There is no known meltdown security patch for El Capitan other than Safari 11.0.2, perhaps they will release one.

    …sadly, I rushed to update the High Sierra install on my old MacPro 3,1 ( which works very well ) and found I lost the NVIDIA pascal driver compatibility – next time I’ll wait until the NVIDIA drivers are released before updating macOS High Sierra

    Does anyone know if slowdown will occur on Macs if we install any Intel/Apple updates as was suggested when this news broke? TIA!

    This security patch is STILL not appearing in App Store users in SE Asia (Thailand) after 3 days!

      Thank you for posting this because I haven’t even installed Sierra on my 2015 iMac because I was concerned about the negative effects. I have a 2010 MacBook Pro that I updated some years ago and since that update it takes forever to get to the opening screen after I turn it on and it doesn’t connect by bluetooth anymore. So I just leave it on now and only turn it off periodically. It was perfectly fine (and super fast) before I updated it. I also have the iPhone 7 plus. I recently updated it and now my email uploads slowly, the battery drains faster, and it doesn’t work as fast as it did before the update. I’m done with updates and Apple. They sent out an update for my iPad…not happening though. They keep fixing what isn’t broken and I think it’s on purpose so we have to upgrade to the newer models. Nonetheless, no more updates for me. I’ll just buy a new computer when I’m ready…not when Apple is ready.
