This command:
bitcoin-qt -keypool=1000
Is if you are running Bitcoin from the command line (e.g. Terminal in OS x, or a shell in Linux).
You can edit the config file to increase it, see:
https://en.bitcoin.it/wiki/Running_BitcoinYou can see the OS x directory and file you need to edit with the keypool=1000 command.
In the wiki the example shows:
#keypool=100
which means it is commented out. You can edit it to say:
keypool=1000
Thanks, I went into the OS X Terminal and typed in
bitcoin-qt -keypool=1000
but it returned the error message "command not found".
I don't feel comfortable creating & editing a config file. Would love to be able to just use the terminal command, but there seems to be no instructions anywhere on how to actually use these terminal commands.
(LOL. And we wonder why "normal people" don't use Bitcoin yet. This is so many years away from being easy enough for the mainstream populace!

)
I agree about ease of use issues.
Something like this in Terminal (I'll be by a Mac tomorrow but I think I got it):
Code:
./Applications/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt -keypool=1000
This is just the path to the applications folder and then to the binary runtime (the actual program) inside the application bundle.
This will launch Bitcoin, so you want to quit it prior to this command.
