Updating old wallet

[Silverfox]

Hi everyone,

I am hoping you can help me as I have an old wallet from 2014 on my mac (0.8.6.2), which I tried accessing today. On opening it, it says out of sync with 0 connections to the feathercoin network. I backed up the dat file and then downloaded the new Mac wallet from this website. Unfortunately, when trying to open the new wallet, i instantly get a message saying that “feathercoin-Qt quit unexpectedly”. I am not sure whether it is because of the old wallet (this I had closed prior to opening the new wallet) or not. Any help would be gratefully received. Thanks.

Hello.

What version of MacOS are you running. ?

Suggestions:

• move away the wallet.dat from the 0.8.6.2 wallet and start feathercoin-qt.
  if it works well then, the problem is caused by the wallet.dat file. The reason is, that the database used (berkeley db) has moved forward by 2 or 3 versions in the meantime, so that your wallet.dat may have become incompatible.

• If the wallet.dat is the reason for the crash, the only solution I see is the following:

• re-install or restore the 0.8.6.2 wallet from a backup and put the old wallet.dat file in place

• start the wallet

• go to ‘debug-> console window’ (the menus have changes, so you may have to search a bit)

• enter ‘dumpprivkey <your feathercoin address>’ and copy the returned key to a safe place

• exit the wallet

• delete the wallet.dat

• install the latest wallet

• start it and go to ‘settings->debug window->console tab’

• enter 'importprivkey <your feathercoin address>

That should recover the address.

@Wellenreiter this is probably because the user is using an older mac. I need to re-compile the MacOS DMG on the oldest supported version of MacOS in order for this all to work on their machine… (probably)

@acidd I keep my fingers crossed that you can get the old version compiled.

Hello, sorry for the late reply, I have been super busy, now i can concentrate my time on this. Thank you for your responses.
I am using MacBookair, 1.3 Ghz, intel core i5. My macOS is OS X version 10.9.5 .
I am at the moment trying to locate the wallet.dat file then I will do as suggested and report back.
Thanks

I am struggling in finding the wallet.dat file as tried, shift + command + G, then inputed~/Library/Application Support/feathercoin, and also other variations of that, with little success. I will keep trying.

I am going to try upgrading to High sierra to see if this makes any difference

All sorted, phew. It turns out all i had to do was update my version of the OS. Thanks for your help.
