All of the above options are bad and as long as there is no secure, open-source wallet, there is no need to use the Mac system to save your coins, you can choose between Linux or Android or buy a hardware wallet.
I tend to agree with you on this, I didn't see this insight in the usage of Mac OS. Linux OS is an open-source system and I think this is good for the open-source wallet because the owner had full control of it. I found some reason people
switched to Linux OS from Mac.
If you have no other option, then use a good web-wallet, but for small or coinomi Medium transactions.
There's no good in web wallet, they are always didn't have security feature, I dont trust someone with my keys. Coinomi isn't an open source but at least you are holding your private key. It's good for me too.
