Sent via PM, but finally realized why it wasn't posting in the forum (links)
...So posting here since someone else may need/want this at some point:
1) You'll want vmware fusion; there's a trial. You can easily install and uninstall it on a mac if you don't want to pay. Vbox and parallels won't work.
2) You'll need the Samsung USB drivers for phones exe from Samsung's website. You'll probably also want to separately get the Kies binaries (both windows bins).
3) MS offers pre-made VMs in virtualbox format (ova's); these aren't activated and expire in 30 days, but will still sorta work after that (they'll shut down after about 30-60mins after that point). Easy enough to just reimport; not sure how often you plan on using Odin. Kies itself is generally ok on a mac, but nothing else is (aside from like graphics-tab apps, and generic usb file stuff). You'll want to get Win7 vm images. These should work but if not you can google; MS doesn't make a secret of their VMs, they're made for developers to check compatibility between different versions of IE. Get all of these and then decompress, and you'll get an .ova file (links to Win7-IE10 VM archive files removed as I don't have 10 posts yet).
4) In VMware Fusion, you'll want to import the .ova file (.ova's are technically virtualbox images, but vmware will easily convert them to its own format). Once you've imported it go into the VM's settings and allocate 2gb of ram or so to the VM (I wouldn't go much below that; if you have a later mac that shouldn't be a problem; you might be able to get by on 1.5gb though I haven't tried). You'll also want to go into the vmware usb settings and make sure to be prompted when you add a device instead of just attaching it to one or the other or you'll wind up with issues, possibly, later on.
5) Boot the Win7 vm, install VMware tools, reboot, install samsung drivers, and then install Kies if you want Kies as well (Kies may also bridge some driver gaps, I can't remember; I do remember I had a bit of trouble with correct device recognition; I'll keep an eye on this thread and if you have a problem post publicly and I can message you with the proper driver set otherwise this should work afair); the problem, if I recall, was in detecting the specific USB devices/hub, if anything. DO NOT plug in your tablet until all of these drivers have been installed and you have rebooted the VM. You've been warned.
6) Boot the VM, plug the cable into the tablet, and then the other end into the Mac. If you've set up the USB prompting properly (btw make sure you set it to 2.0 not 3.0), you should get a prompt asking if you want to attach it to the Mac or Windows; choose Windows. The drivers should do there thing in a few minutes and eventually recognize the tablet. You may or may not want to reboot the VM one last time at this point before opening Odin, but at this point it should all work.
* A note: you'll probably want to enable a shared folder via VMware with the contents of anything you want to flash and the exes to flash them with; this is pretty straightforward in the VM settings. You'll want to copy/paste from that shared folder to the VM, not run from it; Odin and other stuff tends to hang if you try to run it directly from the share. I just keep everything I need or might want to use in the future on the VM and suspend it til I need it again, but you can just as easily shut it down and it'll retain all of the data, etc; just be mindful of the 30 day limit if you're using one of the precompiled VMs (as I said, they'll still work, but it can get naggy and shut itself down if not in use (or maybe if it is, but I haven't had it bomb out on me mid-flash (yet, knock wood)).
Good luck and enjoy.
