My Cloud EX2 software for Mac not available?

Hello everyone,
I went to WD “Software and firmware download” page here:

WD Sync and 40
But I could not find WD Sync for Mac or WD Access for Mac. The link gave me some “updater” instead.
Please help!

It turns out the installer is inside the updater:
Right click the “updater” then select “Show Package Contents”

The installer is in the “Resources” folder:

There is no .dmg file as mentioned in the instruction.
Why has WD not revised the instructions??
