WD Access for Mac & WD Sync do not like Mojave

MyCloud PR 2100 does not cooperate with iMac running macOS 10.14.2
There is no way to open WD Access for Mac downloaded from https://support.wdc.com/downloads.aspx?p=254&lang=en
There is no way to sign up to PR 2100 (the same local cable network) using Version 1.0.7.13
The only way I can sign in is using browser and log in through WDMyCloud.com
Similar problem applies to WD Sync for Mac 2.0.1.93 downloaded from https://support.wdc.com/downloads.aspx?p=266&lang=en
Every time I try to open WD Sync crashes.
There is number of threads related to above problems but I couldn’t find reasonable solution and WD support does not clarifies the issue (hint on https://support.wdc.com/knowledgebase/answer.aspx?ID=13127 doesn’t work as explained).
Does anybody have any workable idea how to resolve above?

See the dedicated subforum for the PR series as this subforum (My Cloud) generally deals with a different device, the single bay/single drive My Cloud units.
