Just curious, for those of you who use ntp servers on your network, how do you instruct your Mac OS X clients to sync their time/date with the ntp server?
Example: You know you have a time drift (i.e.; clock skew too great) on one of your Mac workstations and therefore your user is getting Kerberos errors. You cant reach the Mac physically (or you are too lazy like me), thus you need to sync the Mac's time/date via the cli over a ssh session. Do you use...
A) ntpdate?
B) ntpd -q?
C) systemsetup <-some option>
I prefer B personally, but Im curious how you guys do it.
I never understood the difference between ntpd -g and ntpd -q, so I always just use the -q option.
I think ntpdate is deprecated, but Im not positive.
I thought that one of the Apple 'systemsetup' commands would poll a ntp server and sync accordingly, but I cant find the proper option. Not sure.

In 1984, Apple debuted the operating system that is now known as the 'Classic' Mac OS with its release of the original Macintosh System Software.The system, rebranded 'Mac OS' in 1996, was preinstalled on every Macintosh until 2002 and offered on Macintosh clones for a short time in the 1990s. (In Mac OS X El Capitan or earlier choose Turn off Time Machine). When you next want to back up your Mac click on the greyed-out Time Machine icon in your menu bar and choose Back Up Now.

Apple began phasing in the use of its SSD-friendly APFS file system with High Sierra for SSD-only Macs, and then upgraded Fusion Drive-based Macs in Mojave. In Big Sur, Time Machine volumes can finally be formatted with APFS, too. But in this transition, one capability was quietly lost: APFS volumes cannot be shared for network access via Apple’s relatively ancient Apple Filing Protocol (AFP).

AFP dates to the pre-OS X days, with a version appearing in System 6 in the late 1980s. As with most older protocols, it got long in the tooth, and Apple went from just supporting the Windows and Linux world’s SMB to shifting to it as the only built-in sharing method. Way back in OS X 10.9 Mavericks, Apple began moving away from AFP in favor of the industry-standard SMB, although it still hasn’t removed support.

In Big Sur, Apple dropped the ability to share volumes via AFP entirely, but even though Catalina retained AFP-sharing support, as noted above, APFS-formatted volumes could not be shared over AFP. macOS Sierra though Catalina “fails silently” in this method, letting you turn on AFP in the Sharing preference pane’s File Sharing section, even if there are no volumes that AFP can share. (Big Sur can still mount AFP-shared volumes.)

I suggest disabling AFP sharing on any Mac running Catalina or earlier versions that you no longer have HFS+ drives mounted or plan to mount in the future:

  1. Open the Sharing preference pane.
  2. Click the File Sharing item at left.
  3. Click the Options button.
  4. If you see an option for AFP, uncheck it. Check “Share filse and folders using SMB” if it isn’t selected.
  5. Click Done.

The only reason this typically matters, however, is on other Macs. When you have a stored alias on one Mac that points to another, and which was a connection originally made over AFP. The alias will still try to work if the other computer is sharing via AFP, even if the volume is no longer shared over AFP.

The solution?

  1. Delete your alias.
  2. In the Finder, choose Go > Network.
  3. Double-click the computer you want to share from.
  4. Enter login information for that Mac if prompted. (If may be stored in your Keychain and the login handled silently.)
  5. Double-click the volume you want to link to.
  6. Select the volume. See below for methods.
  7. Choose File > Make Alias or hold down Command and Option while dragging to create an alias.

You can select the volume in step 6 in one of several ways:

  • In the Locations section of the sidebar, click the remote Mac, then in the resulting Finder window, double-click the volume you want to make an alias from. Navigate up one level and proceed to step 7.
  • In Finder > Preferences, make sure that in the General tab you have selected “Connected servers.” This will make any mounted drives appear on the Desktop, where you can select them in step 6 and proceed to step 7.
