Hello!
I have recently opened my 2011 MAC and I have a 2013 version of bit coin on it.
I have tried to upgrade the bit coin version, however, it says I must have a later version of the MAC OS. I currently have OS X 10.9.5 and I am unable to update the OS, according to the APP store and online information.
The errors I am receiving when opening bit coin are: Urgent, Alert key compromised, upgrade required.  Then my home page/wallet screen says Wallet, out of sync, Recent transactions, out of sync.  It has a blue bar at the bottom that says 'synchronizing with network' (catching up, last received block was generated 2073 days) - 43.74% complete.  After this is open for a while, it will produce error: Failed to write undo data and I must click ok and it closes out of bit coin
Is there anything I can do to upgrade my bit coin wallet, without the ability to update my MAC OS?
I am not sure if I have any bit coin but remember looking into this back in 2013.
Any help is appreciated, thanks!

The best solution for you will be to copy the wallet.dat from your old mac and install a new core version on
a newer mac or pc and synch (that takes a while, because the blockchain is as the time of writing ~269 GB big).
Then copy your wallet.dat to it and open it in bitcoin-qt.

oh wow, thank you.  I did not know you could transfer them/it.  I don't suppose you have any resources that explain those steps of copying and then syncing after installing on a new computer do you?
