2006 mac pro, upgrades from El Capitan

[realpainter]

I have a 2006 intel mac pro and using the legacy patch upgraded the O.S. to El Capitan. Can it be upgraded any further.

Are you running the best version of macOS for your Mac?

Keep scrolling down until you find your Mac listed. That is the latest version Apple says will run on it.

Unfortunately, 2006 Macs are too old according to that article. However, OCLP isn't the only patcher organisation out there - I haven't got the link to others, but a search on YouTube may pay dividends? And OCLP only goes from Big Sur whereas I know my 2011 iMac could be taken as far as Catalina using a different patcher.

That's right, the other patcher I heard about was dosdude. I did come across this, not sure how relevant it is.

Yes it was dosdude - it was via him that I got a High Sierra installer, which is the highest my iMac will officially go (the App Store tells me it's "Installed" which it most certainly isn't!).
