This MacBook (black 2 GHZ Intel Core Duo) would not accept the firmware password I just set via the Firmware Password Utility from the Recovery Partition in OS X Lion 10.7.2.

The following steps let me turn off the firmware password protection. It only works if you haven't forgotten the password you had set. I my case this means I had used the correct password but it wasn't accepted. Seems like a bug, maybe specific to my particular (and rather old) hardware.

1. Open Terminal and type diskutil list
2. Mount the Apple_Boot Recovery HD partition with diskutil mount disk0s3 (use the identifier you see listed)
3. In Terminal type: open /Volumes/Recovery\ HD/com.apple.recovery.boot/BaseSystem.dmg
4. In Terminal type: open /Volumes/Mac\ OS\ X\ Base\ System/Applications/Utilities/Firmware\ Password\ Utility.app
5. Now you can turn off firmware password - again, provided you know the password you had set

Create a directory, move your files into it, issue this command from terminal:
hdiutil create -encryption -stdinpass -srcfolder mysecretfiles mysectretfiles.dmg 

Delete the unencrypted directory you created to start with.

OS X seems to cache ssh-key passwords by default. This is rather useless. You can disable this with
launchctl unload /System/Library/LaunchAgents/org.openbsd.ssh-agent.plist

If you launch Keychain Access (in /Applications/Utilities/), and remove the entry for your ssh keys, you should be prompted for your password, and have the option to not save it.

To ~remove ssh-agent you can could run..

launchctl unload /System/Library/LaunchAgents/org.openbsd.ssh-agent.plist

..or use http://lingon.sourceforge.net/

Or unset the SSH_AUTH_SOCK env variable

Or, look at the ssh-add command - ssh-add -D forgets all identities (including removing relevant entries from Keychain), ssh-agent -t 123 sets it to remember identities for 123 seconds

If Apache won't start in your vserver, giving this error: Address already in use: make_sock: could not bind to port:80 make sure you don't have Apache running on your host system.

As crazy and esoteric it may seem, syncing your Apple AddressBook to Google really only works when your Mac is synchronized with an iPod or an iPhone. Just plugging such a device and syncing with iTunes triggers the sync to Google. You can also edit a file on your Mac instead to get the same result, as describe on Lifehacker.com:
Change the "Family ID." value to 10001 in ~/Library/Preferences/com.apple.iPod.plist

As the blog plugin of Flux CMS supports the MT Weblog API, you may want to use a desktop client for blogging.

The access point URL is http://yourdomain.com/blog/xmlrpc.xml (replacing "yourdomain.com" with the url of your Flux CMS...)

ECTO is a great desktop blogging client, which utilises a lot of the potential of that API. One of the features is a preview pane, where you can immediatly see, how your post will look like on the webpage.

To make it really look like your page, you have to adjust the template. Go to "Settings" -> "Editing" -> "Viewer" and then put this html into it. Adjust the link to your CSS accordingly.

Image upload: It makes sense to keep some sort of order with the files you upload to your server. I recommend adjusting the path in image upload to /files/images/blog/

Also take a look at your scaling and thumbnail settings. A typical width is 480px.

When restoring OS X from a Time Machine backup (or by any other means) you may encounter problems with Adobe CS applications. When you want to start an Adobe CS app, this message can appear:

'Licensing for this product has stopped working'

This is what Adobe have to say about this know issue:
The Flexnet folders/files required to run Adobe applications can get corrupted, or have permission settings problems, if moved from one machine to another, or through a system restore from Time Machine. Flexnet service licensing failures can't be resolved by re-installating the appliaction, nor will the Adobe CS3 or CS4 Clean Scripts solve this problem. If permissions issues prevented the FLEXnet licensing service from launching, accessing its data, or communicating with Adobe processes, the licensing failure is expected.

The solutions may vary, but your best bet is to delete the following folder:

[hard drive]/Library/Preferences/FLEXnet Publisher/
