MyCloud crashes after update when uploading files

After not using MyCloud for a while, I connected it successfully to our new router, and managed to upload a number of big files by way of Wifi connection last night. This morning, when trying to continue with the uploads, I agreed to a firmware update (now v04.04.01-112), being - at that point - blissfully ignorant of the multiple problems that updates apparently create. As a result, I am now unable to upload anything to the device. I can still see it, I can even open files stored on it - but whenever I try to upload anything, it crashes. Being a Mac user does not make life easier (for once), as many of the instructions on the web are for Window machines.

Can anyone tell me whether there is a quickfix? This is what the error report says:

Thanks in advance!

I’d try the ‘turn it off and on again’… uninstall the WD My Cloud app and re-install it, making sure you install the latest version.

Also, firmware upgrades sometimes seem to need a 40-second reset (remove power, press&hold reset, apply power, wait 40 seconds, release reset) to make the MyCloud work properly…

If you’re working locally to your network, I’d suggest not using the MyCloud app for accessing the drive at all; map it into your file system, and use Finder for all file operations.

I’d only really suggest using the app for remote access, or if you want to move stuff around on the MyCloud (since it ought to work a bit quicker, doing all file operations internally to the MyCloud, rather than having to go back and forth to the Mac).

Hello there,

Thanks for your help. But I am afraid I cannot uninstall WD My Cloud, as
it crashes immediately when starting the deinstallation process. I would
very much like to re-install the software: any pointers how this could
be done?

As for the file transfer, your suggestion to go through Finder does the
trick: thank you! I still have no idea why the My Cloud app is so
unstable, but as long as I am able to access the device and shift data,
I am not overly fussed.

With best wishes,

I still have no idea why the My Cloud app is so unstable,

Simple: it’s not very well written, IMO…

I would very much like to re-install the software: any pointers how this could be done?

Mapping your drive into your operating system is by far the best way of accessing it: it means that the drive is available natively to all programs, and you don’t have to mess about saving to local drive and then copying to the MyCloud with the WD App; everything works just like it would with a hard disk drive connected directly to the computer.

I don’t use the App, and I don’t have a Mac, so I can’t help with installation problems… Unless you need it for remote access (which can be done via the web portal anyway), I wouldn’t bother fighting with it any further; it’s a retrograde step in file system access.

Point taken! As they say, if it’s not broke don’t fix it…
Thanks again for your help - much appreciated.
