how can I reset sync services in Yosemite?

It's best to describe the problem in as much relevant detail as possible, rather than what you think is causing it or how you think it should be solved.

TS1627 Any ideas on how to reset sync services on OSX Mavericks?

http://support.apple.com/kb/TS1627 holds no answers. The reset script sited for Mountain Lion doesn't exist for Mavericks.

Thanks, GabrielHay. That's much clearer, now.
I already use iCloud, and I'm looking for the iCloud equivalent of SyncServices (or something other than the suggestions I've found, so far, that will reset iCloud sync). That's what it seemed you were looking for: a way to reset sync in Mavericks, as opposed to a way to sync in Maverics. (Essentially.)
So again, thanks.
That said, there's no evidence that Apple has ever "mined" clients' data or would even care to. You're free, of course, to not like the idea of syncing via Apple's servers. But to suggest that Apple "chose to switch off SyncCervices" in order to "give themselves a bigger database of client data to mine" is simply unfounded.
I'm always amused at the notion that despite Apple having hundreds of millions of customers, a given individual is somehow convinced that Apple would care about his data.
Apple doesn't care about your calendar. Or your contacts. Seriously.
Think of the many thousands of celebrities and dignitaries who use Apple products. If Apple were paying any attention to their data, let alone doing anything with it, the revolt and backlash would be legendary. I personally know many people who have the contact info for hundreds of celebrities and such in their Apple Contacts and Calendar apps, and not one breach has ever, ever occurred.
Consider the unfortunate security breach that Target sustained, last week. It's been all over the news, every single day, for nearly a week. If Apple were doing anything of the sort, no one would stand for it. No one! Apple has far too much to lose to do something stupid like that. And to what end? So they can see where a user's having dinner? Or what time his staff meeting is? Even a celebrity's calendar is pointless. What good would it do Apple to know that Charlize Theron's having lunch with Ewan McGregor. None.
You seem like an intelligent guy. If you think through what you're proposing, you'll realize Apple would stand to gain nothing by doing what you suspect -- and in fact would stand to lose everything.
Thanks again for the clarification. And best of luck!

How do i enable sync services

On my iMac OS X Yosemite, I often get an error "Sync Services is disabled." How do I ENABLE Sync Services software!!!
Thanks, Lisa

Hi Lisa.F,
I'm sorry to hear you are having issues with your Mac. I also apologize, I am a bit unclear in exactly what context you are seeing these error messages (what you were doing at the time), or what the exact error message text is. There is a way to reset Sync Services and re-enable the various sync-related settings afterwards (as outlined in the below article), but Sync Services is only used for very specific (and limited) purposes in OS X 10.10 Yosemite:
OS X Mavericks 10.9.3 or later use Sync Services only to exchange contact and calendar data with iPhone, iPad and iPod Touch devices over USB when using iTunes 11.2 or later. SyncServices is not used to synchronize data with Exchange, iCloud or other services listed in the Internet Accounts pane of System Preferences in OS X Mavericks.

TS1627 Syncing Calendar from my iTouch via USB (sync services) is intermittently unreliable. I'm positively not interested in iCloud. Anybody in the same boat?

Today's immediate problem, described below, appears to be solved for the time being, but I expect recurrence based on past experience. I am not sure whether iCal, iTunes, sync services, or some combination are implicated. Does anyone know how to improve USB sync reliability? Is there a magic utility that can spot and repair trouble, or is there a more reliable system out there? A paper calendar maybe
Tonight I discovered a few events that hadn't made it from my iPod touch to iCal. Then I tried creating a couple new events and synchronizing. They remained on the ipod, but would not show up in ical. New events created in ical did get to the ipod though, quite consistently.
I eventually reset and restored my itouch. And reset sync services using terminal:
% /System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsyn c.pl full
Finally I can get new calendar events entered on my ipod to sync to my mac again, but those that failed to sync before still refuse to show up in iCal. They just have to be deleted and re-entered... assuming I can find them all, which I cannot do with certainty, because I can't easily figure out how long the problem has been going on without me realizing it. I'll probably miss an appointment or two, make a few friends and colleagues unhappy. Again.
Current system details: Synching my iPod Touch (gen 4, iOs 6.latest) to my zoomy retina MBP, running 10.8.4. It's an all-apple setup, no third party apps or hardware involved.
The usual/recurrent problems I've seen with syncing the itouch to iCal are:
Events modified on the ipod will be unchanged in ical. Or more rarely, the other way around.
Related to the above, a dialog box will occasionally pop up asking me to resolve sync conflicts. Sometimes lots of them. Usually my ipod has it right, and iCal hasn't caught up. I wish all the errors were caught this way, because it's pretty easy to correct errors by clicking through this interface.
Events entered on the ipod fail to appear in iCal, or vice versa.
Events get replicated, sometimes repeatedly with subsequent sync. They multiply like tribbles.
I generally muddle through using Apple's help pages, run through a few suggestions from the forums (thanks all), and after a long night of resetting various things in various ways, the bit rot is at bay yet again. A month or two down the road, things go wrong in some slightly different way.
Most of the time I have a positive user experience, but it seems the sync zombies are always lurking just beyond the light of the campfire. Is Apple paying attention to sync services anymore, or have they put all their resources into iCloud? I have no interest in iCloud. I don't want another email address to get spam, and am not comfortable keeping my data in the cloud.

Never mind. Turned iCloud on, then off, on the iTouch - then the expected option appeared in iTunes.

Microsoft Sync Services problem with Entourage (calendar)

Out of the blue, when I open Entourage, I get a dialog box: Microsoft sync services has encountered a problem.
I've isolated it to Calendar in Entourage. I cannot open my calendar. Email works, contacts work - but the error message pops up when I click on calendar.
I've tried to reset sync services through iSync and with a line item in Terminal (/System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsy nc.pl reset)
I 'was' using MobileMe - with calendar & contacts (only) synched, but I un-synched them.
Any ideas?
Thanks!

Ever since I installed Snow Leopard, i get a random error message that sync services has quit, and do you want to send to Microsoft? I always select yes and as of now I have sent more than 160 report messages. This generally happens about twice or three time a day. Some days, the total Entourage quits and has to restart. I do not have the specific problem you describe as calendar works most of the time, but the sync services crash happens randomly. I can find no one who can explain why with Snow Leopard and not with Leopard. Going to Microsoft for a solution is not the answer, as I can find no one there to talk to for free. I use iCal and Mobile Me for my synching, but use Entourage as my e-mail program as I am used to it. I also have sync services active so my Entourage calendar will be up to date, but I make no entries into it.

Hello. I am owner of an iPod Touch 5gen. I have an error "iTunes was unable to load provider data from sync services".

Sync services in outlook for mac in yosemite

Cant seem to get sync services to work in outlook 2011 for mac
i'm using Yosemite on my Imac

You can turn it off under Outlook's preferences. Click on AutoCorrect then AutoFormat. Uncheck the box that says "Bold" and _italic_ with real formatting"

When I connect my iTouch to my PC (windows 7) an error message is displayed reading "iTunes was unable to load dataclass information from sync services. Reconnect or try again later".

When I connect my iTouch to my PC (windows 7) an error message is displayed reading "iTunes was unable to load dataclass information from sync services. Reconnect or try again later". I have completely uninstalled and then reinstalled iTunes. I have also completely reset my iTouch to factory defaults. I have even followed all the advice provided previously to other forum member with the same problem. Nothing seems to work. Please help me someone.

I'm getting the same problem with both my IPad 4 and iPhone 5
Just started a few weeks back, Since then I have had two Itunes updates.
Is this something Apple is aware of and trying to fix?

Itunes was unable to load data class information from sync services.Reconnect and try again later.

when I open itunes I get message " itunes was unable to load data class information from sync services. reconnect or try again later "
I am unable to sync my ipad 2 or iphone 4 through itunes. I have tried all suggested options, removing itunes and related components from control panel + verified completely uninstalled from C program files + then reinstalling latest version of itunes (version 11.3.1.2). Also tried running itunes as administrator. Also tried reset sync history in itunes Also tried system restore on windows 7 from earlier period.Still get the same above message.
I run 64bit windows 7. Have recently renewed my Norton Intenet Security. Everything was OK up till then. Could this have anything to do with it.

A quick cursory browse seems to point that the problem is on Apples end since the last update of iTunes, theres loads of forum posts about it but Apple themselves arent responding as yet other then the usual "unplug, delete sync data, reconnect or completely uninstall iTunes" spiel which doesnt work so hopefully they will fix it sooner or later

ITunes 10.5.3, Unable to Load Class Data from Sync Services, Crashes Repeatedly

Ever since iTunes 10.5.3 on my Windows 7 x64 box, I've been having serious problems keeping iTunes running:
1) Any time I connect my iPhone or iPad, or any time they attempt to sync over WiFi, I get the 'Unable to load class data from sync services' error. It's worth mention that the iPhone or iPad do actually then proceed to sync correctly, and all media / data is synchronized successfully, as far as I've been able to tell. I've reset sync history, restored the iPhone and iPad, manually moved the SyncServices directory, set both the iPhone and iPad up as new, completely uninstalled iTunes and the mobile device software, re-installed, and *nothing* I do fixes this issue or even seems to impact it. Uninstalling iTunes 10.5.3 and reinstalling iTunes 10.5.2 resolves this error.
2) iTunes 10.5.3 has serious crashing problems on my machine, though I've searched through forums and found a lot of other people with the problem. In my case, sporadically as iTunes access the iTunes store (for example, I can always make it happen by subscribing to the Diggnation podcast and telling it to refresh the podcast), I get a full application crash which generates the following event in the event log:
Faulting application name: iTunes.exe, version: 10.5.3.3, time stamp: 0x4f14cc3d
Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
Exception code: 0x80000003
Fault offset: 0x0001280c
Faulting process id: 0x564
Faulting application start time: 0x01cce78789dc009a
Faulting application path: D:\Program Files (x86)\iTunes\iTunes.exe
Faulting module path: C:\Windows\syswow64\KERNELBASE.dll
Report Id: ecc77400-537a-11e1-b809-00248c196007
Again, uninstalling iTunes 10.5.3 and re-installing iTunes 10.5.2 fixes this issue as well, but I really shouldn't have to do that. Is there any actual solution to these problems other than dowgrading to an older version?
Yes, I'm running current malware protection (and my system is clean) and yes, I've already checked any other obvious culprits to make sure I don't just have a corrupt library or file somewhere that's causing it. My Windows 7 install is completely up to date from a Windows Update perspective and also from a driver perspective (even including the motherboard and chipset drivers). I made sure to do a system file integrity check (sfc /scannow) and it confirmed my install of Windows isn't suspect, but beyond all that I was able to reproduce these failures on a completely separate machine running Windows 7 x64, without any of my media library or data on it -- iTunes 10.5.3 just seems to be bad news on Windows 7 x64 for me, even though I know there are definitely people are using it successfully. I don't get any other application crashes for any other applications, and I've never had an issue like this with any previous version of iTunes...
Last but not least, in case it matters, I'm running iOS 5.0.1 on both the iPhone4 and the iPad2. The iPhone4 is the GSM AT&T model and the iPad2 is the CDMA Verizon model.

OK, I've given up. Uninstalled iTunes 10.5.3 permanently. It's a shame, 10.5.2 works perfectly but 10.5.3 is a complete and total cluster for me.
Anyone with the same problems who hasn't done this already, just uninstall iTunes and the Apple Mobile Device Service in your Add/Remove Programs, then re-install iTunes 10.5.2. You won't lose your library or any settings or apps, it will just go back to working again.
I wish Apple would acknowledge this so that I'd at least know it would be fixed in the future.

Error message: "unable to load [...] from Sync Services

I've tried resetting sync history with no avail. On the "Info" tab of the device (iPhone 4), I am unable to check the "Sync Contacts with" and "Sync Calendars with" options. Until about a week ago, it always synchronised with Outlook 2010 without a problem. What can I do to fix this?

Hey KatanaGirl,
Thanks for the question, and welcome to Apple Support Communities.
The following article outlines the exact symptom you are experiencing, including a potential resolution:

Tried to sync iPod Touch, noted "new" iTunes. iPod won't sync ("iTunes is unable to load data class information from Sync Services"). Tried the fix, but iTunes hangs when I try to open Preferences.

Just tried to download new audiobooks to my iPod Touch 3, and noted new iTunes. iPod won't sync ("iTunes is unable to load data class information from Sync Services"). Tried to Reset Sync History per Support Article, but it didn't work. My purchased audiobooks are also gone from my iTunes Library. Any fix, or is my best bet to uninstall new iTunes and reload earlier version??
