Remote iMac Keeps Changing Networks on its Own
As a severely disabled person, sharing is a marvelous help, but lately it's becoming worthless. I try to access the iMac in my office from my MacBook Pro, and it doesn't show. I ran this way for years with no problems. I make my way to my office (no easy task) and the iMac is on line and running fine, except it's switched itself to a different network, which should show on my MacBook Pro, but doesn't, even if I connect the MacBook Pro to the network it is now connected to. All of my computers have access to all of the networks I use, so whatever network the iMac is connected to should show in the finder, but it doesn't. I'm hoping there is a way to lock on to a network so the iMac can't switch to another.
MacBook Pro 13″, macOS 15.3
