OSX Mountain Lion LAMP pear etc Install
If you are really lazy
Install your existing keychains on new mac (there are some files you can just copy, but i can't remember which so maybe give this a go): http://osxdaily.com/2012/07/05/copy-keychain-login-passwords-between-macs/
SSH
- turn on Remote Login from Sharing in System Preferences
- Run
ssh localhost
, the ctrl+c to cancel (cheap way to create the .ssh directory in home dir) - Copy private key into .ssh dir and call it id_rsa (make sure perms are 600 or similar)
