WDMyCloud

New software is available through WD's My Cloud Home's website. The drive and its contents now show up in Finder running on Catalina. Software Version is 3.5.152 :-)

You're not alone. It is a problem caused by Apple in macOS Catalina, zee https://discussions.apple.com/thread/250794335?answerId=252075582022. Try Apple support.

This is a bug in MacOS Catalina. See https://discussions.apple.com/thread/250794335 . I suggest to get in contact with Apple support to ask for a solution.

I'm not a current MyCloud user, but have been researching the Western Digital My Cloud EX2 Ultra today. I came across a thread (somewhere) earlier asserting that using SMB-3 (only) solved many issues. Hope that helps.

That is totally unacceptable. I bought wdmycloud couple weeks ago because tech sales person told me it was best. I use it for my home business and now all my files are unavailable. Using the web app to download the files defeats the purpose. Proposals, quotes, product specs are all out of reach. Your lack of anticipation is causing my business money. Wish I could return it and get an REAL NAS. Thank you Wd for showing how you don’t care.

does WD say the software is compatible?

I have MyCloud not the home version, this didn't help. Seems to be something to do with SMB as I have another hard drive that also won't connect via SMB since this Catalina update. AFP is kinda working, very slow and not compatible with other devices on our network, so not really an option. SMB needs to be fixed. I don't care if it is WD or Apple, this support and update time is unacceptable.

This is seriously inconvenient and unacceptable. I believe users are deserving of daily and at a minimum weekly updates on progress. I'm running 2 64 TB EX4s that house thousands of photos including new ones from a recent trip to Africa that I cannot edit them because of this issue.

Users spend the money we spend on good hardware expecting continuous excellence and this isn't it.

The WD MyCloud drive doesn't show in my finder with Catalina either. I downloaded and installed Discovery 3.5.152 and rebooted the Mac and the drive, no help. I can't connect with SMB either. No more ugly old Windows computers laying around to test it.

I have two WD NAS for years - MyBook Live and MyCloud EX2 - and I am really disappointed about WD Software and Hardware (not only for macOS but also for iOS) and its speed. I am looking forward to buy a real, useful NAS (like Synology or Qnap). My experience with WD NAS was really, really bad. It seems that WD does not care about its NAS at all.

Spent all weekend getting set up, upgraded, and updated to prepare for the work week. Now I'd dead in the water. Catalina was announced months ago. Poor service, WD Discovery.

Thanks Poser!
