vShare via Crossover
Yes.
Download and install "Crossover". It is an app for mac that allows you to run windows applications.
Open up Crossover, click on "Crossover Software Installer" and choose internet explorer.
After it installs, you will be able to run internet explorer.
Now you need to do a search on your normal browser (ie. safari) and find the vshare-plugin.exe. Save it and copy it.
Now, I can't remember exactly what I did here. You may be able to run the .exe by "right" clicking and selecting "open with crossover". Then install in the same bottle you installed iexplorer.
If not, then open up crossover, click on "manage bottles". Then click on "open C: Drive in Finder" and paste the "vshare-plugin.exe" to the "c:\ drive" in the same bottle that you installed internet explorer. Run the .exe while in crossover and it will install inside the bottle.
After this, once you run iexplorer you should be able to watch videos that require the vshare plugin.
I apologize if this was hard to follow. If you run into troubles, msg me and I'll try to help.
