Hello computer gurus of Nairaland,

I recently bought a 2011 MacBook Pro with a macOS High Sierra. Obviously, this MacBook (a 2011) is no longer supported by Apple in terms of updated Mac OSs.

However, I would like to update the os to Catalina or later, as the software - Xcode, Android Studio, Vscode, etc. - I plan to use it for won't support earlier versions.

I couldn't settle with High Sierra now, so I started googling, and found this guy - dosdude1.com - who apparently has a custom Catalina macOS patch that could work on unsupported MACs like mine.

I am not too experienced with the macOS, hence I am kinda scared of making careless and more importantly, irreversible decisions. Mk everything no go lock, yunno. :-)

So I would like to ask if anyone here has successfully upgraded an unsupported Mac/earlier macOS - High Sierra - to later OSs like Catalina? If yes, could you point me to helpful resources, pls.

Or if you've used this custom Catalina patch by dosdude1 before with 0 issues?

Thanks.
