WD Sync Service quit unexpectedly... Constantly on a Mac

Hello,

I have searched the forum but I can’t seem to find any solutions to fix my currently problem. Basically WD Sync only lasts between a couple of seconds to a couple of minutes between being restarted before crashing again. Aside from the obviously annoying problem that WD Sync isn’t working, the popup is doing my head in as even while typing this message, twice I’ve found I’ve been typing in the comments section of the Problem Report!

It could be a seperate fault ,but Time Machine only lasts a couple of days before insisting that new backup is created which it then takes a couple of days to complete.

As you can probably imagine I’m not exactly feeling the love for my My Cloud at the moment! Oh… it’s crashed a four more times since I typed how many times it’s crashed why trying to type this post!!!

Please help me!

Cheers,

Alex

Well, I managed to get both events in one screen shot! The new Time Machine backups take about 2 days to upload to My Cloud and barely last a couple of hours before this pops up. The WD Sync Service quit unexpectedly generally appears within seconds of relaunching, up to about an hour. It’s very frustrating and any assistance would be appreciated.

Please help me!

There must be something I can do?

Ironic!

What does the “show details” button indicate when clicked on “WD Sync Service quit unexpectedly” dialog box?

Apple Time Machine is a separate program/service than the WD Sync program. If both are crashing it may indicate a problem on the Mac computer or a problem with accessing the My Cloud. Are any other programs/apps crashing on the Mac? Are there any problems accessing the My Cloud when Time Machine or WD Sync crash? If connected wirelessly to the My Cloud, does the Time Machine and WD Sync program crash when connected via Ethernet wire to the same router as the My Cloud.

Hi Bennor,

Thank you for the reply.

I copied and pasted some of the show details text into my first message. It was too much text to include the whole lot but the next time it crashes (which sods law will mean it will probably be fine for a day or two) I will try to spread it out over two or more posts.

I had previously been using Apple Time Machine with a portable hard drive via USB without problem. No other programs are crashing, which has led me to believe that there is some issue with my My Cloud device.

I don’t have an Ethernet port on my Laptop so I can’t test that. A USB-C to Ethernet adaptor isn’t exactly cheap but I’d be happy to purchase one if you think it would be a productive test.

Cheers,

Alex

Amazing it crashed again as soon as I hit send!

I suggest you contact WD Support if you wish someone to deal with error reports as detailed as that…

We are users, and can provide some UI support, but crash logs are expecting a bit too much…

I have the same problem now for 2 years and still no resolution, I have literally tried everything imaginable, has anybody gotten to the bottom of this???

For me the problem started some weeks ago and it is independent from time machine, which is not activated on my Mac… And as described, WDsync crashes every 10 second (more or less). To my opinion it is not worth while addressing the problem to WD support. My experience is that they basically tell you: “Bad luck! Why are you stupid enough to use something as exotic as Mac…”

I would recommend using some other sync software. Try FreeFileSync.

Well, I have the same experience: WD Cloud Sync quits immediately I open it on my Mac.
FreeFileSync works only with local storages and does not with WD NAS set up in a different location.
Since WD decided to discontinue WD MyCloud app establishing connection with my PR2100/4100 is avaible over the browser connection exclusively which is definitely slow and unsecure.
Does anybody have some smart solution?

Free File Sync will sync/mirror/backup to a remote location using SFTP. If one can get SFTP enabled and working on their My Cloud it remains an option. FTP is also now available in Free File Sync but FTP is generally considered insecure.

Of course one will need to configure port forwarding of the SFTP/FTP ports so the traffic gets past the network router’s firewall to the My Cloud
