Out of synch...

Version 1.0.3

Oops, pressing return did not result in a new line but a sent review. Lets try this again. I wish there was a better product. I got this because it promised PPC and Intel compatability. However using this is a pain, because once a sync fails - for whatever reason - you are in for a world of pain. Synctogether refuses to sync because there is leftover data. Synctogether refuses to quit because it thinks it is syncing even if it isnt.
You can reset this, but it still does not work as it should. Syncs fail for obscure reasons "check the history file for the reason", but the history fails just says, "Failed, check the history file for reason". One computer looks as if it is still syncing, but you cannot cancel the sync. The other computer looks like it is not synching, but refuses to quit because it "is synching".
At $50, this program is an insult, it feels and works like a $10 shareware from a beginning programmer. It worked for a while for me, but right now it is a maintenance nightmare. Until MarkSpace gets their act together - which I doubt they will - Avoid!


For what it's worth, deleting the contents of the "synctogether" folder in "Application support" seems to make the app work again... until a sync fails again of course. Uninstalling the app does NOT remove this folder! Uninstalling and reinstalling does not help, probably because of this.


From the tip to delete the folder in Application Support it sounds like it is possible some sort of caching or incremental setting syncing that's cauing the issues? Well that would be my first theory.

Have you sought support from the developer? If they are of little help that is petty harsh for a $50 app.

While SyncToGether is not really maintained and it's annoying that it's build as a standalone application instead of a background service, it is working fine for me on snow leopard to sync my addressbook and calendars without having my private data on servers somewhere in the world.

I am a big fan of Mark Space products. Currently own Missing Sync for Palm OS and Palm Pre, but I cannot get SyncTogether to work at all. My configuration is via wifi (802.11n) trying to sync my Macbook Pro and MacPro machines. No dice - keep getting error stating that password authentication is required - no password received. Initially I thought it was my firewall, so I checked that config and tried again - no good. I completely disabled the firewall but the error continued. I then remembered that I have Norton Confidential SW running on both clients and thought that maybe that was my issue, so I completely disabled those protections with the firewall enabled and disabled - no good.

Any ideas on what my problem might be? Check out the knowledge database at the MarkSpace website and that was of no assistance.

Thanks for any help in advance.

Can't get it to work, always get the "An SSL Certificate for user@host could not be generated"-error. Wasted hours with the "solution" on their homepage, no effort.
Finally, this application is pure annoyance.

I needed a syncing solution between my MacBook Pro and Power Mac G4, and at time SyncTogether has worked but there are a lot of times where it will say it has failed, or it just corrupts all your data (luckily I have most data backed up).

The interface is ugly, and why is there a Mark/Space store in this programme? Paid $50 for a programme filled with ads. When it syncs it pops up the window, which is annoying, why can't it be done in the background? Maybe it should have a menulet?

SyncTogether would be good if it actually worked, but $50 for a buggy beta with ads is definitely too much to pay and I regret it.

How wonderful it is that a developer creates a new software and it tunes out to be a most confusing, uneasy and featureless app.

It's adverstised that you could sync WHATEVER you want. Well, I can't find ANYwhere to sync files/folders other than what the app restricts you to. And as for setting up the second Mac to sync with, it makes no sense.

Chronosync is much better, simple, to the point, non-restrictive AND could sync over wi-fi, network, etc.

Don't bother with SyncTogether and BOY am I glad I didn't buy it outright.

Some developers probably feel that the more complicated an app is (or in their minds "feature-rich") the better. Not so here...

Pure and unadulterated garbage!

I am troubled by these reports because - 1) There are no positive reports (not on Macupdate, Versionracker, or on the SyncTogether forums posts), and 2) because the only real report (what does only one report mean, few users or everyone is having a bang-up time?) is negative (lost data, very slow, unstable, etc.).

I REALLY need a software solution like this, and am happy to plunk down my $50.00 (a great deal if it works as advertised), but with the reported issues, I wanted to try a demo first. Sadly, it appears that there is (apparently) no demo version any more. The download links at both MU and VT are pointers to MarkSpace only. What does all this add up to?

Well, it's a big red light to me, screaming : "Warning, Will Robinsons, Warning!"

1) Can someone from www.marcspace.com please comment: what of this (these) issue(s), are they being, or have they been, resolved?

2) Can we get a demo? How?

Hi Dorian,

I am the original developer of MySync (which became SyncTogether). Although I have continued to work with Mark/Space on SyncTogether, I'm writing here in a personal capacity.

As far as a demo is concerned, that's really a Mark/Space question, so I won't comment on that right now.

As far as the user reviews go, if you look back over the reviews here on MacUpdate, almost all of these relate to the original MySync, and most are very favourable. VersionTracker has a few more negative comments, but these all relate to MySync, and are largely from people who felt (with some justification - sorry about that), that they didn't receive adequate support during the transition.

On both sites, the app has a four star, or greater rating.

The SyncTogether forum at Mark/Space is slightly different. This is for discussion of problems with the app, and gives users a direct point of contact with the engineering teams and vice versa. It's not surprising that there are more problem reports than praise there.

In fact, I've been more surprised at the lack of issues, and the low numbers of support requests that have been received.

Some users will always run into problems with syncing - there are a lot of moving parts, including Sync Services and the client applications. For examples that don't involve SyncTogether, see Apple's .mac sync forum at http://discussions.apple.com/forum.jspa?forumID=957

However, the overwhelming majority of SyncTogether user's experiences seem to have been relatively problem free as far as I can tell.

Hope this helps.



I've been trying to get SyncTogether to work for weeks now. I bought it when it was released, updated it when the update was posted, but have had terrible results.

Their tech support respondes, albeit 2 or 3 days after I posted my tech support request. I went through this twice, and am once again trying to get it to work through tech support, but so far nothing works.

One of the ridiculous suggestions posted by their forum's moderator was to make sure that iSync is configured to allow browser bookmark syncing. If I wanted to use .Mac I wouldn't have bought this program in the first place... amazing.

This program has been a complete waste of money, and I bought 2 licenses so that I could use it on 4 machines. So I've wasted $100.

I was really looking forward to this app, as it's predecessor "MacSync' worked quite well for syncing my Yojimbo and other information until recent OS updates seemed to disable it.

Unfortunately, SyncTogether doesn't work correctly for me between my G4 Powerbook and G5 iMac (both using OS 10.4.8), after several trys at resolving the problems. And yes, I followed the suggestions in the help file for troubleshooting.

All my attempts to synchronize Safari book marks, Yojimbo stuff, and address book contacts resulted in extraordinarily long periods of wait (15-20 minutes), and high processor load (on my PowerBook) followed by error messages and a crash of the node on my PowerBook. Contacts and Yojimbo info was partially synched to the iMac, but not at all for the PowerBook.

I guess it's a good thing this product has a demo, because it's not ready for prime time yet.

Works as advertised. The advantage of this program is that it syncs just about anything that you can sync through .Mac, including contacts, bookmarks, etc. It also has a good user interface.

That said, I prefer address-o-sync for syncing addresses. MySync uses Apple's sync engine. It will inform you if information on cards conflict, e.g., if they have the same work number. However, if information is unique to one card or the other, it assumes that you want to keep it and merges the cards. This can result in bad info. For example, if suppose that the old card for John Doe on machine A has work number 123 and mobile number 456. John Doe has moved, and machine B has a new work number 789 and no longer has his mobile number. When you sync, Apple's engine will inform you of the conflicting work numbers, but will assume, because it's unique to one card, that you want to keep the mobile number, even though it's bad.

On the other hand, address-o-sync gives you three options when any information conflicts on the card: Keep the old card, keep the new card, or merge. It's more flexible, and prevents re-importing bad data. In the example above, I could view the card on both machine A and machine B and reject all of the data from machine A, preventing the bad mobile number from surviving.

Ever since it began supporting syncing computers across "remote" networks, MySync has been growing up nicely. Recently, strong security has been implemented and the app is very stable. If you have a need to do some basic syncing of Address Book, Mail, iCal, Safari bookmarks, Keychains, or even Entourage Notes, and you don't have/want .Mac, give MySync a try. Keep in mind that it is still beta, though.
