Why isn't this coming up as an update when I go to the app store and check updates? Only giving one star for the lack of info on this.

You gave it one star because you can't find it?

Of course I found it or I would not be here. I gave it one star because at the time I did not know it was a silent update, not shown by the app store. This was Apple's first ever silent update. And I still don't know if I got the silent update, so I installed the one shown here. I give one star for a lack of information and confusion caused because it did not show up on the app store when I selected updates.

On my Mac it showed up in the App Store, with the title "Security Update". While that title is general, the description underneath clearly states that "This update addresses a critical security issue with the software that provides the Network Time Protocol service on OS X".

If you look at the list of "Updates Installed in the Last 30 Days", does this security update appear there?

Per the actual security article (https://support.apple.com/en-us/HT6601), enter what /usr/sbin/ntpd at a terminal prompt and if any of the following versions come up, you don't need this update. Mountain Lion: ntp-77.1.1 Mavericks: ntp-88.1.1 Yosemite: ntp-92.5.1

After installing this update on my MacBook Pro, I assumed I'd need to do the same on my new iMac. But App Store/Software Update shows no update for the iMac. Thanks to Developer's note, I've verified the iMac is running ntp-92.5.1.

I'm puzzled why the iMac is already up-to-date. The only thing I see that's different between the two Macs is the 10.10.1 update. The MBP was updated on December 2. The iMac arrived on December 17 with 10.10 and was immediately updated to 10.10.1.

Could it be that the latter 10.10.1 update already included the NTP fix (which was independently released on December 22)?

I noticed that Apple claims this is a "critical security issue". Leaving aside how long it has taken for Apple to eventually notice a problem (especially if the word "critical" comes up in a discussion), I was wondering how critical is this fix considering every user does have the option to turn off this time/date network checking in the Date/Time preference pane at any time. I am assuming turning off (once the date and time has been checked, of course) would avoid all manner of nasties from third-party attackers. For this issue to suddenly crop up at this time would suggest either a lot of users are leaving the feature turned on as if that extra level of accuracy is critical in people's lives and could make the difference as to whether or not people make it to their all-important meeting etc, or Apple is trying to look like it is doing a fantastic job at finding security problems and fixing them promptly during this Christmas festive season.

Not sure which is closer to the truth.

At any rate, the fact that Apple has provided a fix (better late than never) and I have found no problems so far during the installation means I'll give this software a good rating.

Cheers Apple!

Oh well. it is good to see Apple has finally caught onto the latest security issue and has only taken a tad over 3 months to find a fix. Either that, or Apple has just heard the news from the Google Security Team on 19 December and has released the fix around 22 December. Since most average Mac users have became aware of this NTP security problem since 22 December thanks to this Apple security fix, a message from Apple on its web site along the lines of, "Users should turn off their Date-Time Network Protocol Server in the Date/Time system preference pane due to a recently identified security vulnerability. Apple will provide a permanent fix soon" would have solved the problem, if not on 19 December, then perhaps in mid-September as you say.

Never mind. I'm glad to see Apple is doing its best to keep abreast of the latest security issues, so long as this kind of work does not impinge on the company's bottom-line in any way.

It's an NTP update. ie. a system daemon so of course it wouldn't have any effect on browsers. It's what contacts the stratum servers to keep your system time proper. Or did I miss something?

No problems with this update on my systems. Firefox, Chrome, Chromium run fine on 10.10.1 and 10.9.5. VPN tunnels, remote access and VNC also working fine. This update fixes what is essentially a buffer overflow issue in the NTP service stack. This fix is very low level at the network stack level, any issues should manifest across a large population of users immediately and effect much more than just browsing. You don't mention if Safari works. If Safari works then look for something fairly high level, perhaps a FF or Chrome extension. Good Luck.

Impossible. This is an update for NTP .. it keeps system time in line with the atomic clock. Your issues are because of something else. Don't be LUSER.
