IT CRASHES WHEN I DO THIS, USING OSX…. type: walletpassphrase [your walletpassphrase here] 600
1) I presume you have encrypted your wallet with a password (skip that command if you haven't.)
2) you removed the "[ ]"
3) you are not typing "type:" or cut and past the text as is, but the command as is.
4) if it isn't user error, test the longevity of the coin and contact the developer - file a bug report.
5) skip the timer but be sure to walletlock.
If option 4 is resolved please get back to us as this will be a sign to investors.
Sorry I can't be of more help.
Thanks for your reply and help, I did type it all correctly.
Developers this is bug needs fixing I think.
Investors its not serious problem it should be fixed soon I hope.
