My Macbook Pro meets all the Sims 3 system requirements. However, the installation goes through the process and gets hung up on file 206 before locking up. I know it's downloading something somewhere, because I went from having 60 GB free, to having 54.21 GB free after two install attempts. But no folder ever gets created, no files appear, I can't find any trace of what it downloaded to erase it. My system is as follows: Leopard 10.5.7, Intel Core Duo, 2 GB RAM, Radeon X1600.
Mac Sims 3 Requirements
Let's make sure that your computer meets all of the Sims 3 requirements. Leopard 10.5.7 is required, so that part of it looks fine. In addition, your computer must have at least 2GB of RAM and 6.1 GB free hard drive space as well as an additional 1GB for saving games and customizations. Computers running either Intel GMA 950 class of integrated cards or Power PC processors cannot run Sims 3. Electronic Arts has an online system requirements checker that you can run to be sure that your system is fully compatible. Once you're sure that your computer has meets all requirements, let's move on to the next steps.
Install from the Desktop
Since you have the CD, you can try to load it onto the desktop and install it from there. Insert the disk and right click on it to open it. A new window should pop up. Right click on Sims3 Installing and Show Content. Copy and paste the contents to the desktop. Open the contents folder on your desktop, go into the MacOS folder and install from there. Many people have found that the "hang" problem goes away - at the very least they can find out the reason for the corruption by using this method.
It's also possible that you have a bad CD or something on your Macbook is interfering with the installation. For example, programs such as Roxio Creator and external devices like iPods and iPhones can interfere with disc authentication as can numerous CD emulator programs such as Daemon Tools, Clone CD, and Nero Image Drive. The Sim3 Support Web site details known software conflicts with the game. Try installing the program with all other applications shut down and all external devices disconnected.
Uninstallers for Mac
Do you have an uninstaller program for your Mac? You may need to remove the bad installation and try installing again. AppTrap is a free uninstaller tool for Macintosh. It may be able to remove your partial installation so that you can try again.
Other Tips and Workarounds Once Sims 3 is Installed
Other users have reported success with Sims 3 installations after renaming the Sims 3 folder and the application. By inserting an underscore (_) into the name, the program was able to be launched.
Is it at all possible that the program is installing but you can't find it? If so, the next time you try an installation, change the installation directory to the desktop. Then you can search for "Sims" in Spotlight to show the icon and launch the game.
Something may be missing in the Sims 3.app folder structure. We suspect that this is preventing Sims3 from running. If Sims 3 is on your system, try this: Right-click "The Sims 3" (under Applications) to Show Package Contents. Now, go to Contents and MacOS. Double-clicking the word "cider" should open a Terminal.app window where you can then launch Sims 3.
Because this is a new launch with some bugs in it, the Sims3 MacForum might be a good resource as things pop up. Hopefully, one of these solutions worked for you, but let us know if you're still having problems.
