Reset Audio on OSX

To reset CoreAudio on Mac OS X without rebooting the machine, use the following command:

# sudo kill -9 $(ps ax|grep 'coreaudio[a-z]' |awk '{print $1}'}

Alternatively, open up activity monitor, and manually search for CoreAudio

Update to Latest FreeBSD Release (9.2)

For my records, here is an outline of the steps I took to upgrade FreeBSD from 9.1 to 9.2.

# freebsd-update fetch

# freebsd-update install

(and reboot if any changes were made)

Now, fetch the upgrades that are included in the 9.2-RELEASE. The differences in configuration files will need to be merged manually.

# freebsd-update upgrade -r 9.2-RELEASE

# freebsd-update install

Reboot with the new kernel before the non-kernel components receive updates:

# shutdown -r now

After rebooting, install the new user-land components, and upgrade 3rd party packages:

# freebsd-update install

# pkg upgrade

To delete the old (no longer used) system libraries:

# freebsd-update install

Finally, reboot into 9.2-RELEASE

# shutdown -r now
