Thanks. I will try that. Meanwhile, some sites have said that I can upgrade to 10.7.5 even though it says you cannot. Do you know if that might be possible?
The DriveDx report shows your laptop being a MBPro 2,2 which according to Mactracker & EveryMac.com is compatible with macOS 10.7.5 Lion.
And if possible, does 10.7.5 fix the vulnerability you mentioned?
No, the vulnerability in macOS 10.7.5 was never patched by Apple. Apple did patch the vulnerability in later versions of macOS such as 10.8. macOS 10.6 did not contain the vulnerability since we were still permitted to use 10.6.
The problem with 10.6.8 is that I cannot get any browser to work any more (firefox, safari etc.) as the older version conflicts with so many websites. I just get a warning that I need to upgrade but I cannot upgrade. Any idea on how to get a browser that fully works on 10.6.8?
You are not going to have any better luck with 10.7.5 either. Chromium based browsers require macOS 10.11+, while Firefox requires macOS 10.12+. Maybe someone has backported a browser to work with macOS 10.6, but I am not aware of any at the moment. A few years ago it was possible to use TenFourFox which was a backported version of Firefox for PPC (could run on macOS 10.6 Intel Macs using Rosetta), but the developer stopped development a few years ago so I doubt it would be of much use these days. Web browsers need constant updates and maintenance in order to keep up with the changing Internet so maintaining a customized backport is a time consuming chore so very few people actually have hardware, or the time and knowledge to do it.
Are you just trying to keep this old laptop running to access the Internet or do you need to use some old macOS apps that are no longer available for later versions of macOS? If you just want to keep using this laptop for as long as possible to access the Internet, then you may want to consider installing Linux Mint to it assuming the laptop has at least 2GB of memory (4GB is best, but this laptop is only capable of accessing at most 3GB). This would give you a non-Apple OS which is current and can use the current versions of the popular browsers (Firefox, Google Chrome, Vivaldi, and others) as well as access to free open source apps such as LibreOffice. However, Linux is not for everyone and it requires you to learn a new OS. Most commercial apps are not available for Linux so you would need to utilize free open source alternatives.
Laptops this old with such limited resources really are not very useful except as a curious piece of history or if you have some old app that not supported with later systems. I like keeping old systems alive, but at some point they are just no longer useful. Until a few years ago I was still using a 32bit only laptop for web browsing and basic stuff, but I ended up finally retiring it once the web browsers stopped supporting 32 bit systems. I really miss that laptop as it was much nicer than most of the current laptops and it only had 2GB of memory (I had ripped out all of automated stuff from the OS which bloated the OS so once booted the laptop was only consuming 70MB of RAM which allowed the browser to use most of the 2GB.
