Thatâs pretty normal on Macs. I have the same issue myself. You can use this guide to get past in very easily. https://osxdaily.com/2012/07/27/app-cant-be-opened-because-it-is-from-an-unidentified-developer/

Hi Everyone - I am working on Bitcoin Programming on my iMac. Any suggestions how to move forward with these exercises on a MAC? Thanks
Hi @CryptoYoga
I donât use a mac, but you will have to find the directory where you installed Bitcoin core and move into it using your console. Once youâre there you will be able to execute commands like on any regular UNIX machine.

Hey @rhotoshi
Did you started the bitcoind daemon in a separate console in regtest mode?
After that you must execute each command with the -regtest option.

Thanks so much for the explanation. The method explained on the video simply didnât work. Your way was so straightforward. Maybe you should run the course!!
ââI would say to smash the like button but it doesnât exist in this courseââ lol
if you interrupt the internet or the power goes out, is there a possibility of losing your balance if they exist in the future? and do the synchronization after the electricity is turned off the internet ,its normal to have problems and lose the wallet?or its possible to recover the wallet? is there a possibility that the balance will be stolen?
The internet would have to go offline in the entire world and even then when it would get back online it would still be stored on someones hard drive and would be able to sync it with the rest of the world. I Guess the only way would be if all hard drives break at the same time 
It has happened before, but that is not good news. If you loose your private key, there is no way of getting your funds.
There is this slim possibility someone will some day generate the same private key as you, but I wouldnât count on it

its possible to mining with bitcoin core client? bitcoin core its the real BTC?
No the feature has been removed because it was not viable anymore. You need third party software to mine Bitcoin today.
Bitcoin core is the full node implementation for BTC yes
