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.

Re: “You tell me not and others say yes?”


when I replied, you had not posted a screenshot of the About This Mac dialog. The only identification you had given us was in your tag line, and it was a partial identification for a different, older Mac than the one you later told us that you had, and a different, older version of macOS than the one you later told us that you had. Usually we need a hardware model year to determine compatibility, but in this case there was no way that any Mac matching the one you described in your tag line could run Tahoe.
