QuoteFix is a plug-in for Mail.app which fixes some issues with replying to e-mail:

it removes the signature from the original message

it removes certain unnecessary empty lines

it positions the cursor below the original message, instead of above it (in other words, bottom-posting instead of top-posting)

Display contextual menus on Dock click-and-hold

To use the old-style contextual menus when you click-and-hold on an applications icon in the Dock i.e. how it worked in 10.5 and earlier, type the following two commands in Terminal dont type the $:

defaults write com.apple.dock show-expose-menus -bool no; killall Dock

All credit for this hint goes to Jeff Johnson of Lap Cat Software, who blogged about the solution. This hint is a significant update to this one, which pointed out you can use Control-click to get the old-style contextual menus. [robg adds: To undo this behavior, you can either change no to yes in the above command, or delete the key entirely with defaults delete com.apple.dock show-expose-menus; killall Dock.]

Screen Sharing in Leopard

As with any other network service, Screen Sharing has a set of virtual “ports” which isolate network traffic for that protocol since it and web traffic and other network services are all using the same IP address and connections. These ports must be opened in all network devices for all computers involved in the screen sharing sessions. This means firewalls on the local computer, as well as any routers or hardware firewalls must also be set up to pass traffic on the following ports:

TCP: 5900 – 5902, (3389 for connecting to Windows machines)

UDP: 4500 (for Back to My Mac users)

Depending on the network devices used, these ports can either be opened completely, or forwarded to the local IP address for the desired computer, but you will have to consult the documentation for your router to see about how to change these ports. Additionally, if your router supports “UPNP” (Universal Plug & Play) or “NAT-PMP” (NAT Port Mapping Protocol), then it should work for Back to My Mac. The list of routers in this Apple Knowledgebase article are some that support Back to My Mac and other screen sharing.

I really need to get around to making the firewall behave for screen sharing.

5 Login Window Tips | Mac OS X Tips

If you find yourself with an overly long list of users in the login window or you just want to get rid of that annoying scroll bar down the side, you can stop accounts appearing in the login window.

Start by go to the Accounts pane in System Preferences, and find the “short name” of each user you want to hide. Once you have these, open up Terminal and enter the following:

sudo defaults write /Library/Preferences/com.apple.loginwindow HiddenUsersList -array-add shortname1 shortname2 shortname3
