The right place to look is one of the sources below (If you are detecting a pattern here, you're right in that the link is http://releases.ubuntu.com/version.number/MD5SUMS. where version number is yy.mm of the release in question. You can also find md5sums for the following at the aforementioned link.
The md5sums for recent Ubuntu versions including Lubuntu Kubuntu Xubuntu, etc. can be found here and previous and point releases and their md5sums can also been found on this page. Drill down through version into release (or source) to find the sum (hash) for your version.
You can check the hash (md5sum) with the command md5sum ubuntu-version-desktop-variant.iso on a Linux system (Changing the name of the ISO file to match the one you have).
You can check the ISO under Windows using the built-in command certUtil (included in Windows 7 or newer), or you can use either the MD5 & SHA Checksum Utility available here or the Microsoft File Checksum Integrity Verifier available here.
The OSX format conversion process is corrupting the file. Write it directly without converting it and everything will be fine.
#NUM=2 #Maybe - check which disk device is the right one
dd if=ubuntu-12.04.3-server-amd64.img of=/dev/rdisk$NUM bs=1m
After you do that the check should complete correctly.
Don't proceed because, even if it happens to be safe this time round, next time round it might turn out that you downloaded a hacked or corrupted image and you won't be able to tell.
I'd use the torrent to download the iso. The torrent clinet should do it's own verification too, and the iso should match the MD5 when it's done, and torrent's often faster.

No. they are not the same. The Md5sums for 14.04 releases are as follows:
The md5sums for 14.10 are as follows:
