Macbook Air (Mid-2013) MacOS Update

[IRONM4N]

Hi all,

I managed to recover my Macbook Air (Mid-2013) 13" to its original macOS 10.8.5. I am not able to get updates on App Store.
May I know how can I update the OS to the latest version?
It seems that I cannot update from 10.8.5 to Catalina.

Any detail advice is greatly appreciated.

Thanks!

cheers

If your on ML, you’ll have a few to go to get to Catalina.

No need to upgrade to each version, one at a time.
Upgrade to 10.11 (El Capitan), then you should be OK to go from 10.11 to 10.15 (Catalina)
