Your tag line says iMac 21.5″, macOS 10.15.


If that is the Mac you are asking about, it will not get macOS 26. Only a few Intel-based Macs will - and no 21.5” iMacs are among them.


Whether you can upgrade to Big Sur, Monterey, Ventura, Sonoma, and/ot Sequoia will depend on the hardware model year of that iMac. If it is old enough, it might not be possible to upgrade it past Catalina at all.
