Transferring chosen files from iMac to macBook Air m3
My old iMac is running macOS Sierra 10.12.6. I simply want to transfer individual files from this iMac on to my recently set up macBook Air m3. I have tried using the 'Target Disc' method with no success. There is no 'Airdrop' facility on my iMac. I don't want to use 'Migration Assistant', as it is not clear to me that I can transfer individual files. I have tried using the 'Server' Connection method but having put correct smb details in I can get no connection between the devices. It seems that Bluetooth cannot connect on either machine.
I have laid down in a Dark Corner for several hours!
