I haven't got the Mini yet, but would like to buy one, if there is a chance of running it with Snow Leopard. I need...

Hi ruchirj33, Thunderbolt is not the same as Mini Display Port. They are only co-sharing the same port on your computer. If you want to connect a TV via HDMI then what you need would just be a Mini Display Port to HDMI adapter. However, if your TV has a high resolution like UHD, then this may not be supported by your system. But: Since your problem is not Thunderbolt related, I would recommend you give us more information about your TV.

I have had the chance to see it myself, including some testing. The Mac Mini was the 2,3 GHz i5. To cut it short: The system was slow, flickering monitor, the cursor (and the entire system) was freezing occasionally, and only HDMI was working. The Mini was booted from an external USB drive. The system was installed on a MBP 2011/Thunderbolt, from the original installer. The same problems occured as SL was installed on a MBP 2007 - from a retail DVD to the USB drive, and updated to 10.6.8. System profiler has recognized all hardware in both cases. I have also checked some Hackintosh sites for tips. But it seems that it is easier getting a Hackintosh to work with Snow Leopard, than a 2011 Mac Mini!

I would like to bring this article to your attention (this was written a few days and answers later): http://www.zdnet.com/blog/government/how-to-install-snow-leopard-on-a-brand-new-lion-based-mac/10652 Summary, as I have understood it: The author has installed Snow Leopard on the 2011 Lion Mac Mini. He has done this while booting from another Mac and connecting the Mini in firewire target mode. Then he has used a regular (retail?) SL DVD that he has bought before to install the system on the Lion Mac. He mentioned that he wasn't sure if Thunderbolt is working. In the talkback someone suggested installing Snow Leopard via virtualization. Interesting. One thing I don't understand is, why has he updated the Mac OS to 10.6.5 and not to 10.6.8? Something else I couldn't find in the article was, which Mini model has he used?
