How to open Bitcoin Core Wallet from Windows - on Mac?

[hogo_fogo]

I have wallet.dat from my Bitcoin Core Wallet I used on Windows PC. Its from 2016. Now I would like to open that wallet on newly installed Bitcoin Core Wallet on my Mac. When I launched that app on my mac, I got new wallet. I would like to use my previous wallet. What should I do? Thank you for your time.

Move your Wallet.dat to the Mac. Afterwards, go to /Library/Application Support/Bitcoin/ and you should see a file called wallet.dat there as well. Rename that wallet.dat to wallet1.dat and shift your wallet.dat into the folder. Start Bitcoin Core and you should be starting to synchronize.

Hi ranochigo. Thank you for your reply. It turned out that I don't have enough space on my Mac to store 350GB+ of data to maintain wallet. So I have installed Bitcoin Core Wallet on my ubuntu box. This box does not have enough available storage on its physical disk either, so I mounted directory, and created symbolic link from my home directory to that mount point

Code:

ln -s /media/truecrypt1/Backups/BitCoin /home/user

 I, as user, can write to that /home/user/BitCoin linked directory, I even created settings.json.tmp there myself. When I check permissions of "/media/truecrypt1/Backups/BitCoin", its 'drwxrwxrwx'.
Unfortunately, when I launch BitCoin wallet that I configured to store everything in /home/user/BitCoin, I get following:

Code:

Error initializing settings: Failed saving settings file:
- Error: Unable to open settings file /home/user/BitCoin/settings.json.tmp for writing

Any suggestions, please?

Thank you for your time.

Why not just run Bitcoin core with the pruned mode in your mac? Around 2GB is enough and it will sync with the recent blocks.

You can edit the bitcoin.conf file or if it's not available in your Bitcoin folder you can make one add something like

Code:

prune=N

The N should be the MB. If you set it to 0 it will disable the pruned mode and the minimum amount to enable pruned is 550 you can increase it to 2000 (2GB) as my suggestion above but you can use the minimum amount just to enable pruned mode.

Hi BitMaxz, Thank you for your reply. My valet I want to use has last activity from 2016. Can I still run it in pruned mode? Will it sync my valet? Thank you.

Yes, it should be sync with the recent blocks and your balance is already in the network so it should be shown the correct balance after synced.

The only problem with the pruned mode you have limited features like using Bitcoind/bitcoin-cli you can't able to use them but if you need this feature then you will need to disable the pruned mode.
