I think Exodus wallet for Mac might be good choice since you said you're looking for a Multi-coin wallet. Exodus supports over 100 assets and since I have experience in using it, it is very easy to manage. It is secure if your desktop is malware free and you can even take back up of your private keys and keep them offline, just in-case you lose access to your desktop, so that you don't lose your coins. The only reason why I stopped using Exodus was that there was no way to adjust the fee whilst making a transaction and it seemed a bit high to me sometimes. Especially, while I was making a smaller transaction.
