Broken screen-sharing after ARD-update to 3.7

Hi all,
I have a MacMini (Mid 2011) running 10.7.5and am only accessing it via apple remote desktop. Well, actually I WAS, since I updated ARD two days ago. From there on screen sharing does only work when the firewall is disabled.
In Console, when trying to connect, I can watch this message coming up:
Firewall: Deny screensharingd connecting from xxx.xxx.xxx.xx:52425 to port 5900 proto=6.
This message repeats until I abort the connection attempt.
I looked at the entries in System Preferences/Firewall/Firewall options (this may be called slightly different, I'm translating from a german localization) and deleted screensharingd, but it continues to reappear. Also, setting it to "allow" does not work.
I added screensharingd manually via the "+", which stayed as it should, but now I have a second "screensharingd" entry in the Firewall, which is set to deny connections and can only be set to allow until I try to reconnect.
I spent some time going through other posts and tried a lot of suggestions, but to no avail, so I saw no other way than posting this question.
Any help is greatly appreciated.

thanks CaptMargnX,
I already disabled the firewall to be able to use screen sharing.
are you saying that this is a confirmed bug?

Screen Sharing and ARD broken

Hi,
I have 10.9.4. I had remote management switched on and it was working fine.
I installed ARD 3.7 and started it up fine and it was running fine allowing me to do all what I needed.
I also need to remote to this Mac and so set the preference in ARD to allow control whilst the app was running. Thats when it went pear shaped.
It suddenly stopped allowing remote access to the machine.
I now have to be physically at the unit. I have removed ARD and all the files it has added and switched off all screen sharing and Remote Management in Sys Pref. Restarted and switched on Remote Management again.
I can still not access the machine remotely (i.e. screen sharing).
When trying to use screen sharing on the Mac itself to remote onto another machine I get the following in Console.

I can ssh to the machine fine, just not screen share (VNC).
Any help to fix allowing VNC to the machine would be greatly appreciated.
Regards
Keith

Further,
I have run a port scan and confirmed that port 5900 is open.
When using COTVNC it sort of sits there trying to connect but doesn't show the screen. If whilst it is trying I switch off Remote Management then COTVNC instantly throws up the error that screen sharing is not enabled.
Thus I am deducing that the actual VNC server of the os is goosed.

Screen sharing and ARD windows to other computers are invisible!

Hi

Please advise

ahhh, thanks you did it!

Screen Sharing dead since update,

Hello,
I've been using Screen Sharing from my MacBook to my MacPro for many months.
Since the latest update - nyet.
When I try to connect using screen sharing, nothing happens. Nothing.
No errors - nothing.
I can use Chicken of the VNC to connect just fine, but it's not the same.
Is it possible to downgrade or reinstall screen sharing?
TIA,
Mike

Thanks for your response.
I can't say which update with specificity.
I believe it was immediately after the 10.5.5 update.
I remember installing the remote client update and hoping that would fix the issue.
I cannot connect to the MacPro from the Macbook at all.
I can connect to the MacPro (both SS and File sharing) from my Mac-mini.
I can connect to the Mac-mini from my Macbook (both SS and File sharing).
I can connect to the Macbook from the Mac-mini.
I cannot connect to the Macbook from the MacPro at all.
I am logging into the admin account (more accurately the only account)
I have checked the screen sharing settings, and nothing has changed.
the firewall has the appropriate ports open and forwarded.
I'm baffled.
It's as if my Macbook and MacPro have just decided to stop speaking to each other. Although I can use 3rd party VNC back and forth.
I suspect something flaky with Bonjour/SS on the Macbook.

Can connect with Server Admin and Server Prefs, not Screen Sharing or ARD

Just set up 10.5 server on my G5, and trying to connect from 10.5 on my iMac. I have tried both with the server System Preferences set to allow Screen Sharing via VNC, and with Remote Management enabled for ARD. In both cases, I get authentication errors when trying to connect from home. I have tried with both the full username, and with the short name of the only account on the server. My assumption is that, since this is the administrator account, I don't need to setup explicit privs for it on the server.
I can authenticate without any trouble with both Server Admin and Server Preferences.
The Firewall is not enabled on either machine, although I am behind a NAT router at home -- is it necessary to open any special ports to enable screen sharing? Is it possible that having these ports closed would produce an authentication error?
Thanks for any help.

Hi
I'm going to assume you configured your Server in Standard Configuration and not Workgroup or Advanced?
When using Standard in setting up the server DNS is automatically configured for as well as the Server taking an Open Directory Master Role. The admin account created at the beginning is for administering the Open Directory. Unknown to you and not documented at all - as far as I can see - is the 'Local Administrator' (localadmin) account.
You only become aware of this account if for some reason you have a problem with the Server which involves demoting to Standalone (ie not an Open Directory Master) once this happens you find you can't log on to the Server anymore or communicate with any of the Server applications because it won't accept any username or password other than root and localadmin for the name and the password defined for the original admin account you created right at the beginning.
Sometimes it does not even take demotion to find yourself locked out of the Server. Some have experienced this problem when running the Security Update or when some other problem has occured.
Part of the process of creating an Open Directory Master involves the creation of a 'special' directory administrator account. This account is used for administering the LDAP node. If demotion takes place this account gets blown away along with all users and group accounts that exist in the LDAP node, in fact everything to do with Open Directory is destroyed apart from Users' home folders.
Why demote if this happens? Sometimes the LDAP database gets damaged/corrupted beyond a point where normal troubleshooting methods fail. This can happen for a whole variety of reasons but more often than not is due to a poorly configured DNS Service. You basically only have two options once you reach that stage. A server reinstall involving a format and rebuild or a demotion to Standalone. Which option would you choose? Prior to demotion you can (if you have the chance) export users and groups or even archive the LDAP database itself for restoration later on. This is a useful option as everything to do with the LDAP Server is retained - passwords, users, groups etc. The other method of saving users etc does not retain passwords.
As time goes on and you become more familiar with your server you will find more and more of this information out for yourself. Hopefully the simple advice I've given helps you understand Open Directory a little better.
Hope this helps, Tony

Home Sharing After iTunes Update to 11.1.5.5 - HELP!

I am unable to enable Home Sharing after updating to iTunes 11.1.5.5.
I've updated my Apple TV (3rd Gen) along with iTunes 11.1.5.5, restarted all my devices (iPad Air with iOS 7.0.6, iPhone 5 with iOS 7.0.6, Apple TV 3rd Gen and Windows 7 64bit PC), restarted my cable modem and router, logged out of iTunes Home Sharing, then back in, restarted my PC AGAIN and verified that all my devices are on the exact same network. My firewall settings are completly unchanged since prior to updating to iTunes 11.1.5.5 and I've verified this. I've also even tried switching all devices to the other network band on my router and switched them all back to no avail.
This has become so cumbesome with Apple every time there is an update, I crindge every time I see one available. Someone at Apple needs to WORK THIS BUG OUT!!! Or, Chormecast will be my new friend!! I thought Android devices were buggy, but I'm having second thoughts as I've NEVER had this much trouble with such a simple networking concept. iTunes Home Sharing has seriously become a complete mess!!
Any advice here???? All I want to do is watch my movie!!!
My Setup:
iPad Air WiFi 32GB, iOS 7.0.6
iPhone 5 64GB iOS 7.0.6
Apple TV 3rd Generation (connected to wireless router via WiFi)
Windows 7 64bit PC (connected to wireless router via ethernet CAT5)
NetGear WDNR 4500v2 N900 Dual Band Wireless Router (Verified all devices logged into the same network)

No file sharing after system update

Yesterday, I performed a System Update. Since then, my Z61t has not allowed file sharing on my network. Prior to and after the update, I have made no configuration changes to my file sharing settings. I have checked the settings, and they are proper. I have tried unsuccessfully to stop and restart sharing. The Z61t and its shared drives and folders can be seen from other network computers in their respective My Network Places, but when trying to connect to any shared drive or folder of my Z61t, I receive an error message. The error message states that the drive is "not accessible." It also states, "You may not have permission to use this network resource," and "Not enough server storage is available to process this command." Not even the Shared Documents folder is available on the network. This is not a firewall issue, because I have tried unsuccessfully to connect with the firewall turned off.
Will some kind soul please help me determine what the problem is and how to fix it?

Try if your network works ok.
Start command promt in Z61t
type ipconfig
Start command promt in your other pc
type ping "ip addred of z61t"
IF this fails your network is not ok or firewalled.
also try to disable simple file sharing from folder options.

Dual screen problems after last updates

Hello everyone,
it was long time since our Arch gave me some problems, but then now I'm fighting furiously with dual screen configuration with new gnome. Let me explain.
I upgraded the home PC that I hadn't update for months, so I updated more or less everything ... kernel, nvidia drivers, gnome, etc..
The PC has always been dual screen (no twin view, without xinerama), two screens (one on a LCD monitor and one on a TV) where I could run separate applications independent.
Now, after the update, when I launch any application in the second screen (the TV) it starts on the first (screen).
Obviously I have't made any changes to xorg.conf before and after the upgrade. I also tried to recreate one with the nvidia-tools but nothing ...
Can you help me? Someone had the same problem?
I post my xorg.conf, I hope that someone has a hint. I can no longer watching movies on TV and it is very annoying!

Writing the post a tried to install fluxbox, and then... all ok. In fluxbox all works fine. I think this is a problem related to the new gnome screen configurer.
I post an image of gnome screen configurer vs nvidia-tools.
Googling around I found that new gnome screen configuration (using xrandr) is not compatible with nvidia drivers. Could be this the source of the problem?
Help please

Hi,
Does your Mac go to the sleep status when you close the cover? If so, the remote session can be terminated due to time out and the time out value may be redesigned in the latest versions.
Thanks.

Screen sharing after abort

Hi there,
I had to abort a screen sharing session without shutting down properly the session but by turning off my macbook. Since then, any new log-in is impossible from the macbook. The loginin window replies: wrong user name/password. But log-in from any other machine will allow for a screen sharing session to the mac mini snow leopard server. Is there anything still running which prevents me re-logging in?
Thanks for help.

Hi L18, and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
Open Keychain Access in Utilities, use Keychain First Aid under the Window Menu item, then either check the Password under that item, change it, or delete it and start over.
Resetting your keychain in Mac OS X...
If Keychain First Aid finds an issue that it cannot repair, or if you do not know your keychain password, you may need to reset your keychain.

Lost iTunes Sharing after latest updates

I was sharing my iTunes over an Airport Express/Ethernet network among three Macs (Powerbook G4, iMac G5, G4 DA) and a PC). I updated all 3 of the Macs to iTunes 6.0.4, OS 10.4.5 and latest Security Update. (I did not use Software Update; I downloaded from the Apple Downloads and then applied the updates to each computer. I did the usual permissions repair, etc.) I can no longer share iTunes to or from the iMac. The Powerbook will share with the G4 DA. The iMac and the Powerbook are both networked over the Airport so the Airport Express is not the problem.
The iMac lists both of the other computers in the "Source" list "Shared Music" but when I try to choose one of the other computers, I get the spinning beachball and then after a long time:
The shared music library "Other Computer's Name" is not accessible for an unknown reason (-3259) (or sometimes (-3263))
Check that any firewall sortware running on either the shared computer or this computer has been set to allow communication on port 3689.
I have checked the firewall and sharing settings and everything is correct.
On the other 2 Macs the iMac doesn't even show up in the source list at all even though it is set to share all the music. I am guessing I need to reset a preferences file on the iMac.
I tried searching on this topic in the knowlegebase and earlier discussions, but it seems all the pertinent links are broken.

I thought I'd mention this... After upgrading my PowerMac G4 with 10.4.6 I suddenly couldn't share printers. The printer and the PowerMac G4 wouldn't even appear in the listings to connect. It was like the G4 disappeared.
For the life of me I couldn't figure out what happened. Then finally I found the problem. The network on my wireless airport was connected to another wireless network. Somehow during the uprade my G4 was pointing to someone elses wireless router signal it was picking up.
You can verify this if you click the airport icon on the right side of the OS X toolbar menu. You can then select your own airport network.
This of course is only if you use an airport network.
Just a thought and wanted to throw it out there.. Simple problem but it took me a little while to find it. And it happened immediately after upgrading the G4.

Flickering Screen issue after Mavericks update released on Feb 26, 2014

I own a Macbook Retina display bought in early 2014. After installing the recent Maverick update released around Feb 26, 2014 the display developed flickering problem while scrolling and now the scrolling is not smooth any more. The originally shipped machine did not have this problem. I tested other software including Photoshop and the display still flickers while panning the canvas. I also tried resetting the SMC - System Management Controller but it didn't work along with other attempts of resetting the disk permissions, running a systems cleaner, changing the wifi-router etc.
How to fix this flickering screen issue?

The problem came back lately and I tried this solution and it worked. Go to system settings > power saver > and switch off the Automatic Graphic switching. Not sure if this is a good solution, but it seem to have worked for the time being.

Black screen mirroring after ATV update

hi, I need help, I just bought my ATV, and it mirrored my IPad just fine, then it asked me to update the ATV software, now it just give me sound but no mirror??? Only a black screen. Help please!

I have the same problem. After restarting the iPad, mirroring will work for 2 or 3 times and then after that I get a black screen on the TV.
It is not a router issue because my iPhone and MCP all work fine sending to ATV repeatedly. It's just the iPad that is having this issue, the one place I really need the capability.
I've tried everything suggested on other threads with this topic. The only thing that works is rebooting the iPad, but the problem crops up after 2-3 uses. I really need to be able to turn mirroring on/off repeatedly like I can on other devices.

Get "screen junk" after newest update to 10.6.7

I have a Mac Pro using dual monitor. Every 10 minutes or so the display on one (or sometimes both) monitors goes crazy. Here is a screenshot of what I mean by "screen junk." http://i55.tinypic.com/34rgo41.png
It is getting really annoying and makes it impossible for me to use my computer. This started to happen right after I got the latest Mac Update.
Can anyone advice?

What you are seeing there is not garbage. It is a deterministic repetition of small screen areas over and over. This might be caused by an addressing problem in the graphics hardware.
Have you run the Apple Hardware test from your original DVDs? It does a gross check for memory integrity on the card.

VZ Navigator Screen Dim after ICS update

Since the update to Android 4.0.4, the VZ Navigator application my Droid Razr Maxx is almost unusable during the day. Entering the application immediately dims the display so low that it is almost unreadable. Exiting the application immediately returns the screen back to normal.
I have disabled 'night' mode on VZ Navigator, uninstalled and reinstalled the VZ Navigator application (currently at 8.0).
Has anyone else seen this behavior?

I have the same problem after I accidentally installed ICS this afternoon. Also affected Navigator unless kept touching the screen at timeout. Called tech support--no help. Read threads then TRIED THIS TEMPORARY SOLUTION:1
1. Go to Preferences->Display->NIGHT MODE->ON.
2. Set Night Mode Brightness to 100 (slide right).
May have to take phone display off automatic and manually set brightness.
I also set screen timeout to 10 minutes for Navigator (Google) to prevent dimming until solve that one too
A few other points. VZNavigator, which was working perfectly on my Droid Razr Maxx prior to ICS, provides your speed and posted speed limits on screen. Has a better display in some ways (3D is pretty real) and has found better routes at times. My wife has a Droid Razr and now also agrees VZN has some advantages. Neither is perfect, glad to have both so when one is not working or gives bad route can switch to the other. And it's $5/ month and worth it.
When she upgraded to ICS, it caused battery drain almost visibly dropping. Full charge gone in less than an hour.
I also found some apps are SLOWER in loading on my Maxx and ICS changed my settings on email and other apps. I personally do not like the newer visuals/graphics--harder to see, some controls easier in previous version, widgets had to be reloaded after power down trying to solve dark screen problem.
Lots of things they could have fixed instead of an "a la Microsoft" let's give 'em lots of "new" features and looks (even if they don't like it). After all, we're Microsoft (substitute Verizon)--we're big, we don't have to care.
I loved the tech response (translated) "we'll get to it".

Cannot adjust screen brightness after BIOS update

I was able to adjust my laptop screen brightness but after the BIOS update:
https://bbs.archlinux.org/viewtopic.php?id=132077
I'm not any-more able to adjust it by hitting F2 / F3
Any good suggestion on what to use to manage volume, /brightness etc? or why now isn't working anymore?
Thanks.

HI,
thanks for the heads up, however I think the problem could be related also to my keyboard layout.
Current
cat /etc/X11/xorg.conf.d/10-synaptics.conf | grep -i model
Option "XkbModel" "hpdv5"
Actually my HP is dv6 and I see now that the keyboard is totally different:
DV5 http://images.google.com/imgres?q=hp+dv … 29,r:0,s:0
DV6 http://images.google.com/imgres?q=hp+dv … 29,r:1,s:0
What Xkbmodel should I use?
Currently available:
$ cat /usr/share/X11/xkb/rules/base.lst | grep -i hp
