Trying to update my iMac
Trying to update my iMac (Retina 5k, 27inch, Mid 2015) to the latest software. Currently on OS X Yosemite and my computer is saying there are no updates.

FWIW, Catalina does not support 32bit apps so you either have to update any 32bit apps you want to run, replace them with an alternative or upgrade to Mojave.
