If you have a mac and you're p issed off because SFM isn't for mac, here's your solution.
Get SFM for Mac:
You will need: A good mac, and A GRAPHICS CARD. Check SFM requirments.
1.) Go to http://portingteam.com/files/file/7477-steam-windows-version/
and download the windows version of steam. Source is built-in, not big surprise.
2.) After you download and install it, find and download Source Filmmaker. Make sure your graphics card is installed, and run it!
UPDATE: A friend of mine got this to work on his 2012 iMac. It runs beautifully, without any problems as long as you ignore the occassional bug or two.
REMEMBER: Your biggest nightmare will be rendering. True Story. Your computer will be around 30-40% slower when it comes to downloads and stuffthan normal, nothing you can do about it.
ATTENTION! LAPTOPS AND SHTUFF: You're not completely hopeless. I run all my Steam stuff on my Retina Mac Pro, and yes, IT HAS NO GRAPHICS CARD. Installing one would mean saying goodbye to HD Retina Graphics, until I unplug it anyway. More importantly, here's how to get a graphics card to work with your laptop. Remember, IT WILL BE BULKY AND REQUIRE A POWER SUPPLY. But it's a solution, and it works pretty well, as long as you keep it clean, dry, and out of the hands of the 5-year olds that play TF2.
Build Your "External Graphics Card"
YOU WILL NEED:
-A SFM-Compatible Graphics card (Windows Comp.)
-Thunderbolt-to-express card adapter (which can be expensive, so if you need to, get 2 cheaper adapters, (I reccommend firewire) however, the key here is fast graphics so don't use too many adapters, it will slow graphics down A LOT.)
-Express Card (NOT AN ADAPTER, an ACTUAL expresscard)
-PCI Express Adapter
-Power Supply (I reccommend http://www.newegg.com/Product/Product.aspx?Item=N82E16817182199
-Basic Computer Knowledge
-Willpower not to throw your Mac at a wall
1.) Buy all of the things. All of them.
2.) Unbox all of the things. Put all of the things in front of you. Try not to panic.
3.) Take your graphics card and attach thr PCI express adapter to it.
4.)Take your express card and jam that into the other side of the PCI adapter.
5.)Take your thunderbolt-to-express card adapter and attach that to the express card
6.) Attach thunderbolt to your mac (With dramatic music in the background, while you make a dumb face and hold your breath) and then when the music breaks into the main part after the cymbal crash, plug your graphics card thingy into your computer. TA DA! Then, if you haven't already, follow the steps above and you're ready to run SFM!
This WILL work! If you have any questions or comments, or just want to annoy me- go ahead and comment below!
