All Apple is willing to say is "Fall 2014".
No it cannot
Yes, you can update your iMac from OS X 10.9.5 to OS X 10.10 (Yosemite), provided your hardware meets the system requirements for Yosemite. You can download the update from the Mac App Store. Make sure to back up your data before proceeding with the installation. Additionally, check for any available updates or patches after the installation for optimal performance.
The code name for OS X 10.10 is "Yosemite." This version of Apple's operating system was released in October 2014 and introduced a flatter design aesthetic, improved Continuity features, and enhanced integration with iOS devices. Yosemite aimed to create a more cohesive user experience across Apple's platforms.
There was no new OS X released to the public in 2006.
No, OS X Yosemite will not delete your data. I installed it and it did not delete my data. Just in case, you might want to copy the most important files onto a flash drive or put them into the Cloud. This way, if something glitches, then your most important files will still save.
Yes, The Sims 4 can run on OS X Yosemite, as it is compatible with macOS versions starting from OS X 10.7 (Lion) onward. However, for optimal performance, it's recommended to have the latest updates and a system that meets or exceeds the game's hardware requirements. Make sure your Mac has sufficient RAM and a compatible graphics card to enhance gameplay experience.
