I have been trying to find a way to play these these games. I have a mac book OS X. Cannot seem to find a way. Anyone have an idea how? Come onnnn mac users.

There were Mac versions, however I believe they were designed with System in mind, rather than Mac OSX. As such, assuming you can find a legitimate copy (its long out of print in the Mac format) of the game you may have trouble getting it to work even with Rosetta.

So you're left with getting the PC version to work. Fallout 1 was originally built for both Direct X (Windows) and DOS, you may be able to get the DOS version to work under Dosbox, but I've not heard of it being done and the graphics are slightly worse than the windows version. You'll need to find a CD version to ensure this is going to work. Fallout 2 was only built for Direct X, so this option isnt going to get fallout 2 to work.

The simplest option, and the one I have to recommend the highest is to bootcamp and install windows and then simply buy from gog.com or Steam. If you've got a Macbook Pro, it will even run new Vegas well (I'm using the high settings). This has the disadvantage of having to buy a windows license. Of course this leaves out old Powerbook users.

If this isnt to your fancy, or you're running a low powered macbook, you may want to try CrossOver Games. They've given Fallout 1 and 2 a Gold Medal for compatibility (expect to install and run with only minor bugs) Tactics and Fallout 3 get silver (Usable, but buggy) and new vegas gets bronze (Installs, runs, and accomplishes part of its intention) However even with their gold ranking they still appear to be officially unsupported. As with all emulated environments you're starting to make things a little more complicated than they should be, so you're going to lose performance, and you are going to have to pay for it. If you're running an old Powerbook, you need not apply.

Thanks a ton for the information. I just have a few more questions if you do not mind.

What requirements should I look for on my mac to play FNV? That is like my dream haha.

I have steam on my computer already, so looks like my next goal is to buy bootcamp?

Forgive my ignorance of macs haha.

If you're running a MacBook with an Intel Graphics chipset, you need not apply. If you've got a Macbook Pro, as long as it was built in the last couple of years you should be ok

Bootcamp is a feature of Mac OS that lets you run windows... So you don't need to buy bootcamp, but you do need to buy a legal copy of windows.

How many GB should I have it at? 50/50?

Its up to you. Depends on what you plan on doing with each "Side" of your computer.

How many GB would you recommend to play FNV?

I was successfully able to play Fallout 1 & 2 OSX versions on an iMac with a 9400m and a MacBook with a 320m both under Snow Leopard. They did not work on an ATI x1600 iMac or an Intel GMA based Macbook.

Apparently the official word is that Apple nixed 8-bit 256 color mode from Leopard/Snow Leopard which causes a black screen or rainbow artifacts. Similarly this also affects Windows 7 PCs although only the rainbow artifact and there are plenty of patches to correct it.

Either way, if you have an nVidia-based Mac there is a good chance it will work, they are PowerPC apps but they run perfectly with the built-in Rosetta

So is 150 GB enough you think? I'm on a mac OS-X

If New Vegas is all you're going to do, then its more than enough... It really depends though on what you're planning to do with the computer. Do you intend on watching movies, if so will you watch them in OSX or Windows? Are you planning to play a lot of other windows only games? Etc.

Only thing I need windows for right now would be for games. Not many compatible windows games.
