I came across the following issues and solutions while working with macosx:
1. Failed to login either without further message or some FileVault error $HOME may still be mounted. see mount, then unmount your home dir, e.g. hdiutil unmount /Users/test See also Best Practices for Using FileVault.
2. Resolve intranet hostnames via VPN Suppose foo.bar is the internal domain name on the other side of a VPN connection. And hosts under foo.bar can not be resolved by the default name server. Then, without changing the DNS configuration globally, there is a rather elegant solution within the mac's name resolver:
$ cat /etc/resolver/foo.bar nameserver 10.0.0.1
See $ man 5 resolver for further details.
3. GPGMail Key pre-selection GPGMail, the one must-have Plugin for Mail.app, selects keys for encryption automatically, based on the recipient's email address. If either this email address is not listed under the appropriate key (see gpg --list-keys), or the receiver is a mailing list with several subscribers, the automatic key preselection fails. That is, unless groups have been created in ~/.gnupg/gpg.conf like so: group everybody@foo.bar = 0x12345678 0xABCDEF12 0x00000001 See also: $ info gpg
