Once the session start’s click on the session window then on the top bar of your mac you can see screen sharing click on it, then click on preferences and a window will appear with settings for display quality and users; Under display, you can select. May 29, 2019 Sharing your screen remotely is a convenient way to access another computer as if you’re sitting in front of it. OS X and Windows have this ability built right into them, meaning you can easily share your Mac’s screen with Windows PCs, and vice versa.

Will this only work if you are using a 10.5 Mac and trying to connect to another 10.5 Mac? What if I have a Mac running 10.5 and the Mac I am trying to control is on 10.4 or 10.3.9? Right now I am using Chicken of the VNC and they are using VineServer. Can they continue with VineServer and I will be able to connect to them with the 10.5 Screen Sharing app? Just curious.

The screen sharing worked last night for me connecting from my MBP running 10.5 to my MacMini G4 running 10.4 just peachy. I had previously been using Apple's RDC product to do that, so I don't know what other setup might have been necessary if screen sharing hadn't been turned on already on the mini.

Yes, you can use Leopard's Screen Sharing app to connect to Mac's running older versions of Mac OS X.
Leopard's Screen Sharing app is just a VNC client (like Chicken of the VNC). It is the first time a VNC client has been included in the client version of Mac OS X. AFAIK, it is a normal VNC client, so can connect to any VNC server, even those running on Linux or Windoze boxes.
Keep in mind that even the client version of Tiger (and i think Panther too) has a built-in VNC server, which can be activated from System Preferences. So you do not necessarily need to run a non-Apple VNC server to control Mac's running older versions of Mac OS X.
I have a Mac on my LAN running Tiger, with Screen Sharing enabled in the System Preferences, and my Leopard Mac sees it automagically via Bonjour; double clicking its icon in the Finder automatically initiates a Screen Sharing session. Too cool!

I didn't expect the app to go that fast. However there appears to be a glitch with my Sony Xperia X2, every time I launch the app it changes my display settings, switches off Super Vivid mode and I then have to manually go back into settings and change back, which is why a bit of an annoyance.'

Does this app also let you type in an http address instead of the IP address? That's how I have my current VNC client setup (so I can access it away from home) and would like to continue using it that way.

Yes, you can type in something like this:
vnc://imac.local
And it will prompt you for the username/password.

I was actually wondering if it would allow true internet addresses (mapped to the appropriate IP address), such as http://www.something.com. I have my computer IP address mapped to and dynamically updated to an internet 'http' address so that I don't have to remember my dynamically changing IP address (dumb cable company).

http and vnc are different protocols, but they use the same addressing. It will work with any hostname as long as it can resolve it to the IP address of a computer running a VNC/ARD server, but if you use http for the protocol part of the address, it will think you're trying to access a web page (or possibly webdav share) and it will connect the wrong software to the wrong port and you won't get screen sharing. In the case of your example, you would want vnc://www.something.com (although it's unlikely that the www subdomain will be used in this case).

I was offered a penny for my thoughts, so I gave my two cents.. I got ripped off.

Don't forget, you can also type 'vnc://xxx.xxx.xxx (the x's are the IP number) in Safari. It'll launch the Screen Sharing app.

This implies that it works using VNC, so Macs running older OSes should be available.. (..in response to the first comment too.)

What password does it ask for?

It asks for the username and password of an account on the Mac to which you are connecting. I wasn't able to get it to work with my default long name ('firstname lastname') but was successful by changing it to my shortname ('firstname'). Then my normal password worked.

Oh, so it is just VNC? That's disappointing.
I hoped Apple could create some smarter protocol that would be aware of windows, scrollable views, buttons, etc. so basic UI interaction could work quickly without transferring all the pixels over the wire.

So many apps today -- particularly on OS X -- are full of custom widgets and eye candy that what you're suggesting it really more trouble than it's worth. Bandwidth is cheap and the compression used by VNC is good and fast.

When the server has a decent driver built in to the OS that knows exactly when and which pixels have changed (as seems to be the case here) there's not much gained by doing things the hard way, and a lot to be lost in complexity and incompatibility.

VNC is a standard tool, with software for almost any platform you can think of. Using this makes the Screen Sharing feature vastly more useful for people working in mixed environments. I applaud Apple for building useful, free VNC server and client tools right into Leopard.

Absolutely.
The expanded availability of screen sharing seems to indicate that Apple have seriously overhauled their VNC server. The VNC implementation in ARD is notoriously cruddy, implementing neither the better encodings, nor the server-side hooks into the windowing system necessary for good performance.
99% of the experience of a VNC session is decided by the quality of the server. One that's tightly linked into OS X's compositor should perform very well.
Looking forward to 6pm tomorrow :)

When it's as well implemented and as fast as Apple have made it this time (a VAST improvement over the VNC implementation built into ARD), I'm glad they've stuck with a tried and true protocol - meaning that I can use it to admin a wide range of hardware that already supports VNC.
Right at this moment, I'm using Screen Sharing to access an old Windows 2000 server. Works beautifully and is noticeably faster than CotVNC.

It's actually a lot better then just vnc. I have an xp pro machine with ultravnc server on it. On the mac I connect to server, type in vnc://11.22.33.44 (the ip of said machine) it brings up the screen sharing app and asks for a password with the option to save it in keychain [sic] It then has the following message:

The computer '192.168.0.15' is running a VNC server that does not support Screen Sharing keystroke encryption. Text you type to this computer may be intercepted over the network. Do you want to continue connecting anyway?
If the remote computer has Remote Login or SSH enabled, you can select the 'Encrypt all network data' setting in Screen Sharing's preferences to connect securely.

I get two things from this. First off, the implementation in leopard supports encryption (by default vnc isn't).
