Recover from a problem with an Apple update System 10.5
Leopard only hintI recently performed a security patch along with a Safari update (I believe it was 5.0.1) using Software Update. I ignored the iTunes 10 update that was available. After the update, I could no longer access any websites, webdav iCal shares, or even connect to the Software Update server! I assume that the security update works for most people without doing anything harmful, but the only way I got Internet access back was by installing an earlier combo update at the Apple Store.

I spent all weekend trying everything I could think of. You can see a list of the things I tried in this Apple discussion forum thread. I had even performed a restore from backup from my Time Capsule (but it's possible that I miscalculated the date on which I performed the patch).

The problem was weird. I got a message from both Safari and Firefox claiming I wasn't connected to the internet despite being connected via ethernet cable (directly to the modem) or airport (at full signal strength). I was able to ssh into other computers as well as share screens with other computers in my house by running screen sharing and manually entering their DHCP addresses. In fact, that's how I posted to the Apple discussion forum. My machine is an older one (a G4 PowerBook), but I found another post on Apple's forum recently of what sounds like the exact same issue, but under 10.6.

The only thing that worked was to run a 10.5.8 combo-update that they had at the Apple store. They agreed that the thing which caused the inability to access the Internet was either the security patch or the Safari update.

[crarko adds: I haven't tested this one. This sounds like something got messed up with the DNS server settings or the address resolver. I wonder if dscacheutil -flushcache to flush the resolver cache might have helped. Anyone else have problems with that update?]

Be wary of Security Update 2010-005
Authored by: karog on Sep 16, '10 08:05:22AM

Another thing this update broke was the PHP-MySQL connection. For local connections, MySQL uses /tmp/mysql.sock. PHP also used this as a default but this update changed PHP's default to /var/mysql/mysql.sock. For me, this manifested in a broken mythweb reporting only a Database Error. The solution is to edit /etc/php.ini (after copying php.ini.default to php.ini if necessary) and change the mysql.sock references in three places to /tmp/mysql.sock.

Check Proxies or VPN
Authored by: googoo on Sep 16, '10 08:30:11AM

I had a similar problem one time and discovered that I had configured my computer to use a ssh tunnel with a SOCKS proxy perviously and I had forgotten to disable it when I closed the ssh connection. Safari would not connect to Web sites and would tell me that I had no Internet connection, but I could connect to ssh servers through the command line. The solution was to disable the proxy. I suppose you could have the same problem if your Network setup was configured to use VPN but you had no connection to the VPN server.

I don't think it's a very good idea to go recommending that people don't install a security update.

correlation does not imply causation. i don't think posts like this should be allowed as a "hint" until properly vetted and confirmed by multiple sources.

This is not a hint by any stretch of the imagination. It borders on FUD, sorry to say.

@crarko - Hints like this should not pass administrative review. Not only is it advocating users to reduce their security by not installing the update, but the hint itself neither mentions a known problem or a known solution.

As another user pointed out, it is quite likely that there was a proxy or DNS issue - neither of which the OP mentioned as tried in the support forum post. Apple's own Internet troubleshooting workflow suggests the user check DNS settings as the second step. A simple web search would have returned this article.

I do not think it is necessary or helpful to the community to mirror a highly user-specific thread from the Apple support forums on this site. This hint essentially says: "I don't know what went wrong, and I'm not sure why this other thing fixed it." This site has always been about hints - intelligent tweaks, undocumented options, and clever fixes. I think that to retain its usefulness, you should reject unknown problems with unknown solutions. That is the work of Apple's support forum.

Actually, I did check the DNS entries, though I neglected to mention it. In fact, I went through each and every nook and cranny of the network preference pane and perfectly duplicated the settings on another computer I had which did have internet access. I even ran ipfw on the command line to make sure I hadn't manipulated my firewall recently. Nor did I have any proxy settings. I'm no noob when it comes to this stuff. I have a pretty sophisticated wireless network at home using WDS and I have various servers, such as web and mail servers.

And regarding not installing a particular security patch, the next security patch will install all uninstalled security patches. I asked about that at the apple store and that's what they told me. They roll up everything you're missing and install it when subsequent patches roll out so that you don't have to perform install after install all through the history of patches. So if you skip one, it eventually gets installed anyway in the next security patch. (Hopefully by that time, the issue will be discovered and resolved.)

I'll admit though that I did not find the precise cause of the issue other than the update, so that's a legitimate complaint, but if no one ever posts this sort of thing, then no one's going to be able to find a workable solution to their problems. I had posted in forums and googled for 2 whole days before submitting the hint and got no workable solutions. Perhaps by making this post/hint, someone will figure out the precise problem.

That is the kind of extra information that makes hints like this helpful - providing ALL the steps you took so that users who are having similar issues can try all of the possible solutions. Their issue may not be identical to yours.

Skipping troubleshooting steps dilutes the benefit of writing the hint in the first place. I think it is even more ambiguous now that @crarko has edited the title.

The value of this site is that it is not a user support forum. Nearly every problem on a Mac can be solved with an OS reinstall, or an update package. This is old hat and completely not unique to the issue you were having. As another commenter mentioned, correlation does not imply causation. I would prefer this site to stick with "cause & solution" as opposed to "correlated event & general solution" hints.

I do not question your Mac expertise - in fact it sounds like you've done exactly what I would have (after your response). I think, however, that it was sufficient to have this post stay on the Apple support forum. No need to duplicate here.

Well, you've got valid points. I actually wondered whether or not my "hint" would get accepted due to the fact that I couldn't find the exact cause and the solution was rather heavy-handed. I wouldn't have begrudged it if it hadn't gotten posted, but at the same time, I wanted to help anyone else that happened to find themselves in my situation. This is the first time I'd even had to go to the apple store to resolve a software issue. Every other visit has been due to hardware issues. But I was at a dead end and I don't think I'd have thought of a combo-update. I'd always been able to avoid coming to that before.

Personally, I think the backlash from the hint is an over-reaction and I think that responses like some of those posted here can serve to prevent people from sending in hints if they think they're going to get reamed if it's not admin-quality, regardless of whether the complaint is directed at the site admin or the submitter themselves. The whole thing is probably karmic given my complaint about the domain name change a couple weeks ago, but the complainers are going to end up damaging the site more than anyone else could. I was just reading how to win friends and influence people last night and it says that you can only make people do or not do things by being positive, not negative.

I've resisted vocalizing my disappointment with this site until recently. This hint crosses the border of legitimate technical advice, and instead lands in shoddy blog territory.

Authored by: Typhoon14 on Sep 16, '10 10:34:27AM

This definitely does not belong here. It's a well-known fact that for any given software update, there will be a small percentage of users for whom the update process does not go smoothly. If you post every hint from someone who has a problem updating, you'd have thousands of posts a day on that topic alone.

Now, if the user was able to identify a particular situation in which the update will cause problems every time, and provide a solution for this, that would be hint-worthy. As it stands, however, this hint just serves to confuse users. Reinstalling the combo update has long been standard operating procedure when a security or system update goes awry.

I had very much the same problem. I updated but did not update the iTunes package on my PBG4. I lost internet connection and Safari/Opera/Firefox acted strangely when I tried to login to my modems. The update combo package fixed it as well as the Onyx clear cache function. I already knew how to fix things as I've used Macs for so many years, however newer users might not have known this. I hope someone with a similar problem doesn't ask the posters on this thread for help. Yeah, it's not much of a hint but perfectly valid. You guys sound just like Microsoft developers.

DEFINITE PROBLEM,
Not sure what is causing it but I have had 4 customers in the last few weeks with the same issue.
Had to reinstall the System to correct the problem.
All I do are Mac repairs so I see what is going on in trends and have been searching the internet for a solution.

I don't agree that this hint is a bad hint. Simply put, it is not uncommon for an OS update through Software Update to break something. That's why you should always download and run the combo updater instead of using Software Update, which is what the person did to fix the problem.

That is not what he said that he did. He said that he installed a Security Update, plus the update for Safari to 5.0.1. Then he says that he had to install the Mac OS X Leo 10.5.8 Combo update over the top of his broken system to get his internet connection to work properly.--- Dah•veed |David Allen| Monterrey, NL, Mexico

Recover From . . . Is A Valid Hint
Authored by: ex2bot on Sep 17, '10 07:32:44AM

I couldn't disagree more with the comments that this shouldn't be a hint. Just because this may only impact a small number of people shouldn't preclude it being a hint. Look through the hints; there are many, many that are esoteric. That is, they are probably only helpful to a very few.

Andrew's argument against the hint was that this is not a "known problem", yet there are at least a couple comments mentioning they had experienced something similar. That makes it a "known problem."

Typhoon14 complained that the hint submitter robleach did not provide a solution. Correct me if I'm wrong, but I believe one reason for allowing comments on the site is to enhance the hint, to provide additional information, to provide . . . _solutions_. And that has happened over and over on this site. It's an important reason Hints is such a fantastic resource.

It is an excellent archive, and this hint increases the likelihood that someone searching the site or Googling for "software update safari 5.0.1" (or something similar) brings someone to a possible answer.

For goodness sake, I know people hate change. Doesn't mean the site is going to the dogs.

I observed the same.

Today, I reinstalled 10.6 from the DVD, network was working. Then I installed all available updates, network failed to work. Since there was nothing else I did in between, it must have been the updates.

The symptoms are: "ping www.leo.org" complains it cannot resolve the host name. But "host www.leo.org" resolves it just fine and returns an IP address. Then "ping" to that IP address tells me I have connectivity.

Safari tells me I'm not connected to the internet, but entering an IP address as URL works.

Now I'm going to read up on combo updates, wondering how to transfer them to the machine without name resolution.
