Accessing Muse via Screen Sharing has bizarre mouse behavior

When accessing another Mac using Screen Share... built in to the Finder, I can see Muse, but any attempt to edit a page displays strange mouse behaviour. Specifically, clicks down and up seem to be mis-interpreted as clicks held down by Muse, and only by Muse. Other apps don't show this behaviour. 100% repeatable, and easy to reproduce -- just click on an object and try to move it and you'll see how it's tough to unclick and stop dragging things around. Seems to be specific to Muse.
Using Lion on local machine, Snow Leopard on remote computer running Muse. Licensed on both locations, just sharing to give design advice.

See this at MacFixIt.
...and 'Google' for, say, "screen sharing black window" and you'll have some suggestions.

Why can't I connect to my Mac Mini via Finder (but I CAN via screen sharing)?

My problem concerns a quad-core 2.0 GHz Mac Mini Server (mid 2011, I think) with SSD and 3 external hard drives. It's (a) my desktop workstation (b) our Time Machine backup repository (c) iTunes server and (d) Printopia server for our iDevices. That's it. The only thing I use the server app for, really, is Time Machine.
So recently we lost power a couple of times. As always, I ran Disk Utility, repaired permissions and verified the main disk. All appeared well.
But all is assuredly not well. Now, none of my other Macs can (a) find the Time Machine backup volume or (b) connect to the server at all. Whenever I try either thing, I receive the message below:
The network is in flawless shape otherwise. My router is the latest generation Airport Extreme Base Station. The server has a static IP, and I CAN connect to it from my other Macs by clicking Finder, then Go, then entering the IP address -- but ONLY if I use an smb:// prefix!
Moreover, even when I'm connected in this way, I STILL get the message whenever I try to connect by merely clicking the name on the finder sidebar -- or whenever I try to access the machine using Time Machine preferences. Weirder still, I CANNOT connect to the ip address via afp.
Final piece of weirdness: I can also connect to this machine from any other Mac via screen sharing. So please....
WHAT'S MY PROBLEM AND HOW CAN I FIX IT? I've wracked my brains, combed through forums and can find nobody else with this problem, let alone a solution.The problem persists when I shut down the server app.
I'm assuming that either something is corrupted or some setting is afoul, but can't figure out what it might me,
I'm just about at the point of reformatting my main drive and reinstalling Mountain Lion, but am hoping someone can spare me that pain.
THANK YOU so much!
Arthur P. Johnson
P.S. I have no problem at all with outbound connections from this bewitched Mini. Just inbound.
P.P.S I will, of course, be happy to provide shots of any other settings you may desire,

For some reason, the error box photo didn't appear in my post. Here it is:

Launch MC via screen sharing

Controlling a Mac running Lion from another Mac running Lion via screen sharing, I can't lauch Mission Control on the remote Mac via gestures or keyboard shortcuts. They always launch MC on the local Mac instead.
On Snow Leopard, when Screen Sharing was the active app, every action (mouse/keyboard) happened on the remote Mac.
Any ideas?

This is of interest to me as well. Has anyone found a solution? Thanks.

Can't access iTunes and Screen Sharing sharing services on my mac Mini

Since several weeks now I face a networking issue of the stranger kind.
Currently I've got my Mac mini acting as the central server for music, photos and files in my home. Central Network Mgmt device is a Wireless Lan router.
In the past I was accessing the Mac Mini from my MacBook via Screen Sharing this doesn't work anymore. When requesting the service the connection effort just runs idle. In iTunes on my MacBook I can see the Libary of my Mac Mini iTunes but clicking on it brings the rotateing ball and after a certain while the message that the iTunes Libary is not responding and that I should check my Firewall settings. Which I did on both computers and they are wide open. 'Ipfw show' in Terminal brings back the message 'Open for any to any communication' also on both computers.
Makeing use of the File sharing service from the MacBook to the MacMini works but it takes a extreme long while until the shared folder appears on the MacBook.
Trying to access from the Mac Mini my MacBook for all these services is no problem.
One more thing is that my Mac Mini cannot access the Wireless Lan router anymore thru the Web Browser or thru a Ping. Here I get the message 'Ping Send to: permission denied'. I changed the Router still the same message. Internet traffic is only possible after I manually applied a DNS Server with its IP number.
Anyone out there who could help? I'm close to completely reinstall my Mac Mini but would naturally love to avoid this.

wireduck,
Highlight the music folder and on the keyboard type (Command) + i: on the window that opens scroll down if need and click on the lock on the bottom right. Type in an Admin User name and password. Then under the (Sharing & Permissions:) make sure the users you want to open the folder are listed and that there (Privilege) is set to @ least Read. If not hit the ( + ) sign and add them. After you have that all set up click on the little gear next to the ( - )s sign and (Apply to a enclosed items). that way each user can read the files. After that the little ( - ) sign should be gone on the folders.
Hope that helps.

Transferring Mail from one Mac to another via Screen Sharing

Hi,
I live in California. My Mother lives in Montreal. She has to computers. A Mac Mini and new MacBook.
What I want to do is transfer her Mail from the Mac Mini to the MacBook via Screen Sharing or Remote Management. In other words, I want to do this from my computer.
How does one go about this? What somewhere is needed to make it all work?
Thanks in advance.

you can't screen share between 3 computers. but you can between two. the easiest way is via ichat. users need to log into ichat on both computers and then you can send a request to share screen via ichat. it's also possible to do it without ichat but that might be more difficult that your mother can manage if she is not too computer savvy which I suspect is the case here. first she has to enable screen sharing in her system preferences->sharing. that's easy. but if she has a router (does she) then she need to port forward port public port 5900 on the router to the port 5900 on her computer so that you can get through the router when trying to screen share from outside. particular instructions on port forwarding depend on the router model. once the port is forwarded you can vnc to here computer from where you are by going to go menu-.connect to server in finder. then in the popup enter
vnc://ip.address
where the ip.address is the ip address of her router. she can find it out by going to this website for example
http://www.whatismyip.com/
but all in all, it's much easier with ichat as no port forwarding is required.

Someone was watching me via Screen Sharing

I just noticed someone was watching me via Screen Sharing. I clicked the little button in the top right of my screen and momentarily caught the IP address before they jumped off.
Is there any log for this info that I can get so I can find out who this jerk is?
Please HELP!

As for Back to My Mac (BtMM), I had only clicked "start" to set up that particular sharing option. Occasionally I wish to access my powermac from other locations, but I never was able to get it to work for myself. I tried connecting from my in-law's place (a few miles away), but never got it figured out. I did leave BtMM on though.
As for Sharing options, I did have File Sharing, Printer Sharing and Screen Sharing turned on. Wherever there was an option for selected users only, I did select that. I know specifically that on Screen Sharing I DID have "Allow access for:" turned on for my wife and myself. That was all.

Mac pro cinema display cuts out and can't access Mac with screen sharing

Hi
A weird thing has started happening to my Mac Pro today. After using it for a few minutes the cinema display it is attached to on the Mac Pro just goes black. The Mac Pro is clearly still on - the light is on and i can hear the fans. The Mac Pro shows up on my local network and i can connect to it and access files from my Macbook, but screen sharing doesn't work (i just get the message 'contacting mac pro' and nothing else) and i can't connect to shared iTunes library either, which makes me think it is not just a display issue. I cannot wake the computer with the mouse or keyboard, which makes me think it isn't just a sleep issue. All i can do is physically turn the Mac Pro off, start it up and it will start up successfully and then work for a few more minutes before i get the same problem. I have reset the PRAM and SMC and still have the same problems. Can anyone suggest anything else i can try?
I should mention that i have another problem with the Mac Pro in that it has been spontaneously waking up from sleep and starting up from shutdown, and i still haven't resolved this. I don't know if it is connected to the above issue.
thanks
nick

I have experienced almost the exact same thing with my new 2008 Mac Pro and my 30" Apple display. It has happened to me twice in the last few weeks. The first time I chalked it up to a fluke, but now that it's happened again I searched the forums. In both cases I've had music playing in iTunes which continues playing, goes on to the next track, and so on. So the machine has not crashed in full. I too can connect to the files via another computer on the network, but cannot share the screen.
I have not had the sleep issues you have had.
I'll look at the link you provided in your next post to see where that gets me, but I wanted to let you know you were not alone on this one.

Upgrading 10.8 to 10.9 via Screen Sharing

Has anyone done such an upgrade on the Server? I reckon the Server part doesn't change the matter much given that it's a completely separate add-on nowadays, but still. Screen Sharing and ssh all function properly at the moment and I want to use the usual App Store upgrade method to go from 10.8 to Mavericks. Compatibility/etc problems aside, I'm only worried about not being able to regain access to the box either via ssh or Screen Sharing.

I've done some OS X upgrades that way. (Most recently from 10.6 to 10.9.) It can work. But if anything should go wrong with the upgrade, you're basically stuck and will need on-site help and/or a way to remotely access the keyboard and display hardware path; a network-accessible KVM.
You're also flying blind for some parts of the upgrade, and waiting for the server to reappear can become... concerning.
Have good, complete backups, etc.

Problems using iPhoto via Screen Sharing

To deal with our family's ever-growing photo library, I bought a new Mac Mini with a jumbo hard drive. For now, I want to run this as a headless server so that whoever wants to can work with the photo library from whichever of our other Macs is handy, so I've set it up with Screen Sharing.
So far so good, I've copied the iPhoto library there and things seem to work well except for one important detail: When I try to see/edit the detail of any photo, I just get a black screen! Or rather, the iPhoto window contains a big black rectangle where the photo should be. If I touch the zoom control, the navigation mini-view shows up correctly, but I still can't see the picture itself. Oddly enough, if I look at the detail of a video, I can see the first frame (but no more than that, the "play" button doesn't do anything).
I'm running Mac OS X 10.6.7 on both machines, iPhoto '11 (9.1.3) on the server.
I realize that I can access the photo library directly from iPhoto on the "client" using iPhoto's built-in sharing mechanism, but that won't give me full control of the remote photo library.
Has anyone else experienced this?

Do you see the same if you're working directly on the Mini? Do you see anything in the middle of the black screen? Maybe something like this:
Click to view full size
If so then that's an indication that the file path to the original file has been broken.
So make a temporary, duplicate copy of the library and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
NOTE: You do know that you can connect an external HD to the Mini and let the other computer log into it and access the library on the EHD for full access to the photos, right? However, doing so wirelessly is dangerous due to dropouts that can occur and if they do while the library's database file is being written to the database can be damaged. So if you're wirelessly connected between the two Macs screen sharing would be the safest way to go. If you're wired then the other method would be optimal.

Accessing Desktop via File Sharing Question

I have two Mac's hooked up via my router one using an Airport card, the other wired. One has OS 9.1 the other has 9.2.1 installed. I cant access eithers desktop via file share, I set both up so that you can access them with no luck. I have to open up Netscape and type in a url for them to put up. Isn't there another way to access ones desktop via file sharing but where your able to see the computers on the network??

carboniw,

Screen sharing - enable/disable mouse

When in screen share mode, is it possible to disable the other persons' mouse(s) so that they can view my screen, but cannot make changes to it?
Also, it it possible to then 'turn over' permission of that mouse to specific individuals?
Also, is it possible to share a screen with more than one other person?

No, so then no and No.
Sorry.
You can use the option in System Preferences > Sharing about Screen Sharing and then this will allow you to VNC:// in the go to Server option in the Finders Go Menu

IMAC and external screen--screen flickering and erratic mouse behavior

I have purchased a screen Medion 25.5 inch to connect it to my IMAC 27 inch.
I have noticed two unexpected behaviours:
- from time to time, after the IMAC comes out of the SLEEP mode, the external screen is flickering, I need to put the IMAC to sleep one or several times before the display of the external screen becomes stable.
- since I connected the external screen, the behavior of the mouse is highly erratic, eg when I move the mouse by a fraction of a millimeter, the display of the mouse pointer moves by half a screen, or even disappears completely. I have performed many tests, with several apple mice, a Dell mouse and a Microsoft mouse. As soon as I completely disconnect the screen (not only power the screen down) the mouse works normally again. I have now decided to stop using the external screen until a software update resolves the situation.
Any advice?
Patrick

When my 2008 24" iMac started to die from overheating, two of the symptoms I would see would be white flickering from the bottom going about half way up, like it was going blank and repainting the screen over and over. Also, the mouse pointer would jump erratically to all the edges and corners of the screen. After a few seconds, it might recover or it might freeze. I would use a program like iStat Pro to see what your temps are when you attach that screen. I suspect it may be excess heat due to the GPU now pushing two screens instead of 1?
Also try diags, and all those reset thingies people keep mentioning over and over.
First and foremost, if you have coverage, contact a "genius" and let him belittle you with his expertise.

Bizarre mouse behavior on rollOut - bug??

I built a custom cursor out of a swf file and I am applying
it on rollover to a specific item. That part works fine. The
problem is the on rollOut event (or mouseOut I've tried both same
exact behavior) fires CONTINUOUSLY when I move the mouse to the
RIGHT. It only fires when I move the mouse to the right. Let me
give an example:
app starts, normal mouse cursor
i roll over an item, swf cursor applied
normal behavior is for swf cursor to be applied over the
item, and off when rolled out of it.
if i move my mouse to the right while still OVER the item,
the event fires for every pixel i move even though i haven't rolled
out.
if i leave the cursor on and move off the item and move
around in the application, the event still fires every single pixel
i move to the right. not only does it fire - it fires a rollout
event up the entire chain of my application. it fires an on rollout
event for every single component in the application including the
APPLICATION itself!!
i'm going nuts on this one, anyone have some insight? the swf
cursor is nothing fancy, just a bitmap, text, and one small little
animation with no scripts.

The issue seems to be resolved (after a longgggg time of
debugging) to be related the the X and Y offset parameters of the
setCursor method. My cursor was designed to have no offset so i
left it blank. I tried 0,0 but that didn't fix the problem.
Putting in any number (1,1) seems to fix the problem. this
must be a bug of some sort in the constructor for this class. Can
any of the Mods/Devs mark this as a bug to investigate?

I cant get screen sharing to work on my home network

I am trying to connect my macbook pro to screen sharing so i can access it at my school computers, which are all iMacs running 10.6.6. When i was at school, and connected to the wireless network at my school i could screen sharing through the finder>go>connect to server. Once screen sharing was enabled i just entered the vnc address and it connected flawlessly. When i got home, and i set my netgear router( wireless-n 150 model: wnr100v2) for port forwarding start port: 5900 end port:5900 server name vnc, and set the ip address to my computer, and when i tried to screen share from another macbook within my network through the finder>go>connect to server, i could not connect. Oddly when i connected my mobile me, i cold screen share over the network. I want to do a WAN screen sharing and i cannot figure out how do do it. I would appreciate any help because it is very important that i enable this feature.

I'm a little confused by your explanation (it's late), so I am going to say what I think I read:
You want to set up your home computer so you can access it via screen sharing from school.
The home computer needs sys prefs sharing screen sharing enabled, and sys prefs security firewall must allow it, too. You port forward port 5900 through your home router to that home computer, which may or may not require that you use a static "192.168.x.x" (or "10.x.x.x" -- whatever the router's LAN subnet is) LAN IP address on that computer -- some routers require that computers acting as servers have static IPAs -- some routers don't.
You need to find out what is the public (internet-facing) WAN IP address that your ISP has assigned to your router; it is not the 192.168.x.x (or 10.x.x.x) address given to your home computer by your home router. You can find that by going to http://checkip.dyndns.com on your home computer. Unless you pay extra for a static public IP address from your ISP, ISPs may (and do) change it periodically on you without warning. So vnc://123.45.67.89 may work one day but not the next.
Some routers have a built-in feature to work around this by allowing the router to advise dynamic DNS servers of any changes in the public-facing IP address of the router. Of course, you need to have established an account with a dynamic DNS provider so you have a host name (like lomberg.noip.com or lomberg.dyndns.com). These are generally free accounts unless you want a special name that doesn't have the dynamic DNS provider as part of your host name.
If your router does not have this capability, these dynamic DNS providers have a piece of software that you will need to install on your home computer (the "VNC server") that reports changes in your public-facing IP address to their DNS servers.
Once this is done, then from afar, you can ⌘k to vnc://lomberg.dyndns.com (or whatever you set up your host name to be with dyndns or equivalent outfit) and you don't need to worry about what your ISP has done to you with regards to your public-facing WAN IP address du jour.
Note that with some (most?) routers, when you are on your home network, you will not be able to vnc to the host name or numeric WAN IPA in this manner. I don't know why it doesn't work, it just doesn't. I've had modems both ways -- my current ISP rental modem doesn't while the previous one (which broke so I had to replace it with my current POS modem) did. So in such case, you have to vnc://192.168.x.x of the "vnc server" computer when you are on the same LAN.
You are aware that on the client (school) machine, screen sharing preferences can be set to encrypt all data on the connection, not just the username/password negotiation piece, right? I don't know whether that setting persists across sessions or only persists for the duration of the current session. I wouldn't want my client mouse/keyboard and "server" screen video to be transmitted in the clear; that's why I bring this up.
Does that answer your question? Or did I totally misunderstand what you were asking?

Screen Sharing and SSH sessions freeze occasionally on multiple mac minis

I have 28 Mac Minis at work. With such a large number of minis, I obviously can't have a monitor attached to each of them so I've got them plugged into a network switch and access them via Screen Sharing (both via regular Screen Sharing and ARD) and SSH sessions.
A few of them seem to suffer from intermittent problems however. I'll be using Screen Sharing when the session freezes. It may unfreeze eventually, but I can also usually just quit out and re-connect and it will be unfrozen. The same thing happens when I'm connected via SSH, it will freeze and I won't be able to type in any more commands.
I need help troubleshooting (or if anyone knows what could be causing this, that'd be cool too).
I've tried connecting from both a Mac Pro on the wired network and a MacBook Pro on the wireless network. The freezing seems to only happen on certain Mac Minis as well.
I've tried switching network cables from a Mac Mini that doesn't suffer from this problem with one that does and nothing changed.
I also thought it might be a bandwidth issue at first, despite being a gigabit switch connected via cat6 to the rest of our gigabit network, but even when no significant bandwidth is being used, the freezing still occurs.
One more thing I want to test is the connection between the switch all these Mac Minis is plugged into and one of the other switches that all our other network traffic goes through. I didn't set it up myself so I fear that it might be an old, damaged cable or something. Failing that, I have no idea what the problem could be, which is why I'm posting here.
So, does anyone have any idea what the problem could be? Or any other ideas for troubleshooting the problem? Thanks.
(They're all running 10.6.8, and range from Mid-2007 to 2009 models).

It would be in the system log. However, the next step would be to safe-boot in order to eliminate third-party system modifications. That goes for both client and server. If you can reproduce the problem in safe mode, then you probably have a network issue. Take everything offline except one client and one server, and test.
