2. Make sure any firewall on your Mac don't block Electrum.
If that green circle appears which means it is completely sync with the network which means theres no firewall blocking electrum.
I have same question too if the address being used to sent out funds is listed on view addresses tab.If not then he input the wrong address.
There are 2 possibilities maybe you put a wrong bitcoin address or you use a fake electrum wallet.
I wast aware with that fake electrum wallet,if theres one then it might be a reason but the thing always comes to my mind which this would be an error in inputting the address because its very impossible for those funds not to be credited or doesnt show on the entire history of transactions in electrum.
