access ntp time server in os x 10.1

Posted by: mkuenzel on 2026-06-10 08:27:42

in os x 10.1.2 in the time and date settings the apple time server seems to be contacted but the time/date is not set. Network / Internet is running well otherwise. I tried also the server pool.ntd.org but with no success. Any hints for solving the problem? thanks a lot

it's pool.ntp.org, not ntd

It might be worth reading these:

Disabling NTP on OS X Lion or older

Following a new security vulnerability in the Network Time Protocol software package, Apple has provided a software update for Mountain Lion and newer versions of OS X. As usual, the older version...

Apple's PPC NTP client had a massive security hole. It was fixed with Mountain Lion, which of course isn't available for PPC Macs.

The TL;DR is: disable PPC NTP services. If you want to run NTP, compile a new version. However, this could be somewhat problematic for 10.1.2, as it pre-dates XCode, so the build-from-scratch instructions won't work.

All slightly tangential to the question, but it's best not to run older versions of ntpd on any system, or at least not point them at a public NTP server.

The fix may be in Sorbet Leopard

Yes, I believe it is. And there's a version for Tiger as well. The challenge is getting a fix for 10.0 and 10.1.

at that point I might recommend using a tiny portable ntpdate type implementation rather than a full ntpd, to be honest: most hobbyist uses don't really need anything more than "set time once at startup". There's a number of these.

This is mine (or perhaps I should say it's David Lettier's which I have mercilessly hacked), which should work on anything 32-bit with BSD sockets: https://codeberg.org/cheesestraws/aux-tinyntpdate - the primary goal of this was to work on A/UX but it's not doing anything particularly heinous.

I'm not claiming this is the best that there is, it's just the one I have to hand and I have reasonable confidence it ought to work on early OS X.
