Mit Leopard kam auch die Screen Sharing Funktionalität in den Finder – für Benutzer die mehrere Macs in kleinen Netzen verwalten sicherlich eine willkommende Funktion wenngleich diese im Laufe der Weiterentwicklung von 10.5 eingeschränkt wurden.

Konnte man sich unter 10.5.1-4 (korrigiert mich) noch Funktionen im Screen Sharing Client freischalten die sonst nur aus der kommerziellen Apple Lösung ARD bekannt sind – wurde dies mit einem Securityfix in 10.5.5 (oder doch schon 10.5.4 ?) verhindert.

Eine der fehlenden Optionen kann man sich mittels einem kleinen Terminal Hack unter 10.6 wieder herstellen – die Möglichkeit die Bildqualität zu verändern – wenngleich nicht on the fly sondern als mac typische defaults Änderung die einen Programmneustart erfordert.

Just found that nice article on MacWorld.com

quote as teaser:

One of 10.5’s new features that I use quite often is the built-in screen sharing. You can use screen sharing from iChat, which is great for family tech support, but I’m referring specifically to screen sharing in the Finder. With multiple machines in the house, I often want to see the screen on a given machine while seated at another. In the pre-10.5 days, this was doable, and not overly difficult you had to click a couple buttons to enable things, then run a VNC viewer app to make the connection. But with 10.5, the viewer is now built into the system. Screen sharing is based on Apple’s full Remote Desktop package, which offers more control over exactly how remote screens are shared. Luckily for us, Apple left at least some of that functionality in the more-limited screen sharing application it’s just disabled by default.

First, here’s a potentially easier way to share the screens of other Macs on your network. First, realize that the screen sharing feature is just an application. It resides in /System/Library/CoreServices, under the tricky name of Screen Sharing. Find it now, and drag it onto your Dock, or into your sidebar, or your toolbar whichever you prefer for quick launch access.

Read it….

My conclusion:

1. To run Screen Sharing without using Finder -> Shared, drag:

/System/Library/CoreServices/Screen Sharing.app

to your Dock

2. To enable Screen Sharing’s Bonjour Browser, open Terminal.app and enter:

defaults write com.apple.ScreenSharing ShowBonjourBrowser_Debug 1

3. To enable Sceen Sharing’s ARD-like toolbar, open Terminal.app and enter:

defaults write com.apple.ScreenSharing \
'NSToolbar Configuration ControlToolbar' -dict-add 'TB Item Identifiers' \
'(Scale,Control,Share,Curtain,Capture,FullScreen,GetClipboard,SendClipboard,Quality)'
