I typically use a micro-HDMI to HDMI cable, then an HDMI to DVI-D
adapter, but as long as you've got micro-HDMI on one end and DVI-D (or
HDMI, whichever your monitor supports) on the other you should be OK.

No, the BeagleBone doesn't output analog video, so it won't hook to a
15-pin VGA D-Sub connector.

Should work.

It looks like maybe a bad cable or connection, or possibly a video
format the monitor doesn't like. I'd try forcing something really
common, like 1024x768 or even plain VGA 640x480 using the uEnv.txt
file. Since the BeagleBone isn't connecting, you can edit this file
on another Linux system (probably even your Mac) if use an SD card reader.
Personally, I never like connecting to the 'Bone via USB and always
run either stand-alone with a KB/Monitor connected, or connect via the
wir`ed Ethernet port. Worst case, you can hook a serial cable up to
the console port on the BBB and assign it a fixed IP address.
