It seems like there might be a typo in the question. If you meant to ask whether it is the iMac or the iMac Pro, then the answer would be that both are different models of Apple's desktop computer. The iMac is the standard model, while the iMac Pro is a more powerful and higher-end version. If you meant to ask something else, please clarify the question. **

No, you cannot install macOS Big Sur on a 2009 iMac. The official system requirements for Big Sur specify that it is compatible with the following models or later: iMac (Late 2012 or newer), iMac Pro (2017 or newer), MacBook (Early 2015 or newer), MacBook Air (Mid 2013 or newer), MacBook Pro (Late 2013 or newer), Mac mini (Late 2014 or newer), and Mac Pro (Late 2013 or newer). Therefore, the 2009 iMac does not meet the minimum requirements for installing Big Sur. **

No, the iMac 2011 is not compatible with macOS Big Sur. The latest macOS version that the iMac 2011 supports is macOS High Sierra. Apple typically drops support for older hardware with each new macOS release, so it's important to check the system requirements before attempting to upgrade. If you want to use Big Sur, you may need to consider upgrading to a newer iMac model that is compatible with the latest macOS version. **

To update Big Sur on an older iMac, first ensure that your iMac meets the system requirements for the update. Then, go to the Apple menu and select "System Preferences." From there, click on "Software Update" to check for any available updates. If the Big Sur update is available, click "Update Now" to begin the installation process. Make sure to back up your important data before updating to avoid any potential data loss. **

The decision between the 2017 iMac Pro and the 2021 iMac depends on your specific needs and budget. The 2017 iMac Pro may offer more powerful performance capabilities due to its workstation-class components, making it suitable for demanding tasks like video editing or 3D rendering. However, the 2021 iMac features a more modern design, improved display technology, and the latest Apple silicon chip for better overall efficiency and performance. If you prioritize raw power and performance, the 2017 iMac Pro may be the better choice, but if you value a more updated design and improved efficiency, the 2021 iMac could be the way to go. **
