Achow, thank you very much for your prompt reply. The wallet I am using is the blockchain.info wallet. Do you have a better recommendation of wallets I can use for Mac? Also, what can I do now, I have 2.57 btc in the wallet that is now stuck and cant ever be used or recovered by me? I reached out to their support but not sure what I can expect.
If you want to change your wallet I will suggest stop using any kind of web wallet and install electrum if you have a PC device on your house just make it secure by installing antivirus so it will be secured from malware.
Or you can try Mycelium wallet if you have smartphone.
