how do i install iOS 11 for MacBook Pro Retina Late 2013, at the moment the latest software update is OS X 10.9.5
MacBook Pro 13″, macOS 11.7
Back up your data, check the application compatibility table, click here, and then on the download link for a more-recent OS. El Capitan is macOS 10.11 and Big Sur is 11; if you're actually referring to iOS 11, it doesn't work on Macs.
Catalina and higher won't run 32-bit software; if you upgrade to one of them, use Go64 as well.
