Cannot Upgrade Software
I have an iMac Retina 5k 27'' late 2015 running Big Sur.
I have followed the upgrade advice but all it does is continue to search !
What can you suggest ?
Thanks
iMac 27″, macOS 11.6

1) First off, have a look at > How to upgrade to macOS Monterey - Apple Support
2) If that does not help, startup in Safe Mode as per > How to use safe mode on your Mac - Apple Support and then see if you can upgrade the macOS.
3) If not, then perhaps you have installed some third party AV, Cleaning or Optimizing software that is blocking your Mac from upgrade. If so, un-install the junkware as per the developers instructions and see > macOS - Security - Apple
