Do people still use ethernet in 2016?? :eek:

Ofcourse... For faster , more secure and more stable connections ... Why now !!!!


Anyways this happened to me too.. i restored a backup from time machine to solve it ....

Ethernet > WI-FI
Faster, more stable connection and also I save on battery life substantially by turning off wi-fi and using an ethernet connection.

Nope ... Only Macbook pros and iMacs
 
Well, my MacBook Pro 13 is still not connecting to the Internet via it's Thunderbolt to Ethernet adapter. I've tried everything in the support article including re-installing El Capitan twice now. I don't have the 3.28.1 file nor do I have the 3.28.2 file on my MacBook Pro nor should I since this was to impact ethernet ports and the MacBook Pro 13 doesn't even have one.

So, has anyone got their MacBook Pro 13 working over ethernet. Sure could use some help.!
 
Apple's software is starting to look more and more like windows! Where one hole is plugged and 4 others opened.
One "security update" after another. That is NOT what i moved from windows to apple.
 
MBP 15" here, and this deadly update does not show up in the App.Store. I wonder if it affects the ethernet functionality even via a TB to Ethernet adapter that I use.

Fair enough. However, my gaming PC hasn't had an update that brick any of its ports yet. Makes you wonder...

I think his/her point is that Mac OS is no longer better than Windows, so why go through the trouble of switching. Not saying I agree. Just helping clarify.
 
pretty certain it broke my Mac-mini too!
(or by a complete coincidence my wife's mac mini ethernet failed on Saturday) and was fixed by a complete reinstall.

I guess I was lucky with my timing (and unlucky to waste a large part of the day!)

ironically I'd just moved her from Win7 a few weeks before...

Hmm, very interesting how people read the wrong statements in your actually fairly simple words.

By the way: I use OS X, Windows and several flavors of Linux.
OS X is not what it used to be anymore and so isn't Windows. Latter for the better, save for some policies of MS I don't agree with, but I don't agree with some of Apple.

So I can have the "non-perfect" user experience for less with Windows, why not?
Because I'm already heavily invested in Apple's ecosystem, it's the key reason why I'm still on their gear.
Not the only reason, but yeah.

Good grief Apple.

We had a good run.

iMac and iPad Air 2 now on eBay. I've been contemplating it for a while, but Apple quality has gone downhill dramatically. These guys can't release an OS update or patch without breaking something crucial.
 
How Apple didn't spot the bug in testing???

Fortunately it seems this bug affected only El Capitan so it seems I was prudent to stay in Mavericks.

What next? Apple releases update that disables both Ethernet and WIFI? Given the state of Apples so called "quality assurance" I wouldn't be surprised if that happens during next security update... :mad:

Mid-2010 iMac 27". Following Apple's support doc, went to System Information, Software, Installations. All it had was: "No information found." Under Hardware, nothing listed for Ethernet Cards.

Ultimately, downloading and running "AppleKextExcludeList_10_11" worked for me (at least for now). Hardware now shows my ethernet card, but System Information, Software, Installations still says "No information found."
 
I'm assuming this security update only affects Macs running El Capitan? Did I miss that pertinent info in the article?
 
I did a reboot Sunday morning to freshen up my iMac so my Girlfriend could do some study on it (first reboot in probably 3-4months) and then it applied the update. It wasnt the first time I'd had issues with my ethernet port, though the the last time was my fault (left jumo frames enabled after going from a 1gbit to 100mbit network)

initially I thought the card had died as it wasnt showing up in the hardware list and upon removing from the network connections list, it also couldnt be readded.

I switched to wifi with the intent of fixing it later however as it turns out another reboot later out of curiosity must have grabbed and deployed the new update.

Would be nice if patches like this were announced so you know whether or not it was something that changed. I had absolutely no idea why after a reboot my ethernet decided to not work - and I went to the trouble of digging out an old router, new cables, everything to test.

Well, my iMac silently updated in the background, and after the reboot everything is back to normal. I'm glad I didn't bother reinstalling OS X to fix this.

But Apple's software woes are getting worse and worse and more frequent. Second time Mac App Store blocks me from using my purchased apps in just two weeks.

glad it worked out for ya.

I believe that it's the option in Sys Prefs > App Store called "automatically install security updates and system files" (or something to that effect).

Thank you. I found it. However it says under the 'automatically install' that I will be notified when they are ready. HA ha-ha ha. I was NOT unless discovering that things weren't working was their way of telling me.

I truly wish people like BusyCal (BusyMac) ran Apple. Now there's a company that knows how to provide customer service. John was right on it when I emailed the problem and sent me the fix as soon as it was posted.....all on Saturday even!!!

The Mac OS is quite stable (certainly no less so than Windows) and, critically for me, much more secure. Also, its UNIX kernel makes is much easier for a dilettante like me to dig under the hood a little bit. I'd rather eat sawdust than contend with MS-DOS.

1. It's called OS X now, Apple dropped the Mac part a few years ago.
2. It's not a UNIX kernel, OS X as a whole since Leopard has been certified as Unix-compatible but its kernel is a hybrid BSD + custom code created by Apple called XNU. XNU stands for X is not UNIX.
3. Microsoft hasn't used MS-DOS for nearly 20 years, the NT kernel is actually pretty damn good and secure as well. In fact, it is inspired by the same Mach kernel that XNU is based on.
4. The security nowadays is not about the kernel but the userspace land. You're far more likely to get security issues from the browsers (think Flash/Java applets) and apps. In this case, UNIX does not protect anyone against this. Remember Heartbleed?
5. Apple hasn't been updating their basic POSIX-compatible tools as fast as everyone else (due to their disagreement with GPL licensing) and because of this, they're more at risk for exploits and security issues compared to everyone else.

1. I know. I was just distinguishing between Mac & Windows.
2. Technically true but semantics to most of us. UNIX, Unix-like, Unix-based... whatever. There's been no pure "UNIX" since Bell was done with it. UNIX became BSD became NEXTstep became OS X. Apple itself calls OS X "the most widely used UNIX desktop operating system," and that's good enough for me.
3. Okay. I was talking about how much simpler it is for dilettantes like me (you read that part, right?) to perform command operations in a terminal window.
4. Fair point, but you're making mine too. Remember the Apple-led (righteous) war of HTML over Flash (which Adobe is losing) and caution with Java installations? And App sandboxing? Not saying it's flawless but Apple has done far more to establish its desktop OS as secure than Microsoft has.
5. Oh. I guess I haven't seen as many security issues with Mac O... excuse me, OS X as with Windows.

So I was adding a time capsule to my network last night and I inactivated my Ethernet port. (I'm not getting into the whys, not important)

When I rebooted my retina iMac, I had no Ethernet.

System profiler said no PCI Ethernet installed.

Thought it was a fluke, so I booted via Internet recovery and I was getting an Ethernet interface there.

So I just reinstalled 10.11 and called it a night.

Working fine now. (As an aside, all your data will still be there, you just have to do the 10.11 to 10.11.3 updates.)

Interesting.

????????????????????????????????????????????????
Really? I have this issue and I am running 10.11.6 and its still DEAD. Amazes me that Apple could care less.
