user86379: Im trying to find my Address I sent my Bitcoins to but I do not know how to get into my wallet and since it is quite some time ago, I do not remember from where I sent it. 
While trying to open Bitcoin Core on my Mac theres a popup saying that its unable to connect to port 8333 but the program closes afterwards. 
Since there is a problem with opening the port I want to transfer the coins to an electrum address. For that I need my seed and the Bitcoin Address I sent my coins to. Is there a way to find it without opening port 8333 and synchronising the blockchain? 
Will it be safe to deinstall it and try to boot it again? 
Any ideas, suggestions are welcome!
Thanks 

user60443: First you need to backup your wallet.dat file. Then, since your installation is from a while ago, I would recommend reinstalling bitcoin, and then importing your wallet.dat.
Backup wallet.dat
To copy your wallet.dat on a Mac:
Cmd+Space then type terminal
In terminal type:
cp ~/Library/Application Support/Bitcoin/wallet.dat ~/Desktop
I would recommend also backing up a copy to another computer or disk drive.
Install Bitcoin-core
Download and open .dmg file from bitcoin.org, and follow installation instructions.
Restore wallet.dat
To copy your wallet.dat back on a Mac:
Cmd+Space then type terminal
In terminal type:
cp ~/Desktop/wallet.dat ~/Library/Application Support/Bitcoin/
Then you can export your key to whatever wallet you want.
