JavaFX Stage Paint issues when Mac Screen Sharing

When using Mac's screen sharing application you have to force a stage resize in order to see the Scene content. I don't have this issue when running native Mac apps while screen sharing, only JavaFX applications.

PS, also running Netbeans 7.1.2 gives the same results. I'll post a thread on the Open JDK forum for the mac as well.

Having security issue with SL Screen Sharing

Hello,
Maybe I am missing some new setting in Snow Leopard that increases screen sharing security, but as it is, screen sharing is now insecure on my network.
Prior to Snow Leopard I would log into my Mac from another without selecting the "remember this password in my keychain"... after finishing the session, I would again be asked for my password before ropening a new screen sharing session. All machines on the network were Leopard.
Now, with all macs on the network Snow leopard, on one of the machines I can log on in the morning, work for a while, quit screen sharing, and go back in an hour and start sharing that mac's screen with no password required. Anoyone else can can do this also! I have checked the keychain on the Mac I am viewing from and there does not seem to be an entry there for screen sharing.
On another of the Snow machines it always asks for the password, but on 2 of them, once I have started viewing another Mac's screen a password is no longer required regardless of the fact that I haven't checked that "remember password" .
This means that after I leave a Mac from screen sharing it, someone else has full access to that machine just by clicking on the Share Screen button... unless I can close the hole somehow.
Any ideas or a way to fix this would be appreciated.
Thanks

Hi all,
I just upgraded to Snow 10.6.2 so through 2 separate updates, this security hole on all 3 Macs on my network exists.
To test it I went to an office and opened a screen on another (Snow Leopard) Mac that was set up to allow users only to connect. I then quit Screen sharing, and returned 3 hours later, only to be able to open the Hard Disk window and return to that Mac's screen without any passwords required. I was very careful not to allow the Keychain to remember me.
Since I originally posted I see another thread has begun up expressing essentially the same issue.
I would strongly advise anyone who uses Snow Leopard in a secure environment , at least through 10.6.2, to disable screen sharing or risk unauthorized access, or monitoring, of their Macs from within their networks. Screen Sharing's security settings (if they work at all) do not work on Snow Leopard the same as they worked on Leopard.
I have not found a fix for this in the 3 weeks since I first noticed it other than to disable it, or restart the Mac I started the session from, then it will ask for a password, but that is hardly an acceptable fix in some secure or corporate environments (akin to having to restart in order to empty the browser cache when accessing webMail lol)

LG l1953S sleep issues when mac mini is in stand-by . No cable connected...

Hi ..
Yesterday i started in the fabulous world of MAC with my brand new MAC MINI . The problem that i have is that when the MAC mini is in stand-by the monitor is not in sleep state , and i get in the monitor screen " check cable " . So i have to disconnect manually the monitor when mac is in sleep state .
I am using mini-dvi to vga adapter (original mac ) .
¿What is the problem ?
Thanks a lot ...

Same issue different twist. I have a Sony Bravia that freezes last image before the energy saver kicks in. It also randomly give me the "no pc connected" I have to unplug my mini display port to VGA adapter to re-sync the display.....
very lame.

Back to my mac screen sharing no longer works since Mountain Lion release, even on Lion

I've used screen sharing via iCloud and back to my mac between a 2007 macbook and a 2010 imac. Both computers are still on Lion but screen sharing stopped working when Mountain Lion was released. I've read a number of comments on this forum that people were having trouble since upgrading to Mountain Lion, but I don't think that's the problem b/c I haven't upgraded either machine. I think the problem is something Apple did in preparation for the Mountain Lion release date and it seems to have damaged screen sharing functionality. Anybody else experiencing this or have a fix for it.
As for the specifics, I can still see my "other" machine under shared and can click "share screen," it usually searches for a couple minutes, then pops up the password dialogue box, but then searches for a while and eventually the password box closes, "screen sharing" stays open, but there are no windows associated with it.

I have the same problem, just today (although I'm still running 10.6.8). Every morning I turn on my main Logic mac then fire up my 2 slave macs, connect to them, activate Screen Sharing, and get going.
This morning I tried it, connected to the other macs as usual (I can see/access/alter their hard drives from my main mac) but when I click "Share Screen" I just get the "connecting" dialog box & it just keeps going.
The weird thing is, when I put my laptop into the network via wifi, I can screenshare my main mac's screen (all 3 of them, actually!) but not my 2 slave macs that are ethernet'd to the main mac.
I've tried every solution I could find via google, and nothing is working.

Issue with finder screen sharing.

My iOS development partner and I are currently having issues with screen sharing through the finder. Prior to installing OSX Mavericks there was no issue with adding each other as users to each others computer, but after the install is when the problem started happening. At the root level there are multiple users on each other's computers with our corresponding names but they don't appear in Users and Groups. So, having phantom users on each other's computers, we took them into the Genius Bar at our local apple store. They tried a few different methods, none of which worked, and had us reinstall the operating system and now we're back at square one having to resort to using the "permission" screen share as opposed to just being able to screen share directly though user accounts that we previously set in system preferences. I used the following console command, but it doesn't show the same accounts in the Users and Groups under System Preferences.: (dscl . list /Users | grep -v "^_") Any help or insight would be greatly appreciated.
Currently running Software OS X 10.9.1 (13B42) on both machines.

Found an answer at the following link.

Back to my Mac screen sharing not visible in Finder

I have a MacMini at home which I leave turned on for various reasons. One of them is so that I can access it from work with screen sharing. But I cannot see my MacMini from my Macbook Pro at work.
All of my computers have iCloud Back to my Mac enabled as well as screen sharing. Locally (on the same network) I can see all of my computers but but I don't see it over the internet when I am at work.
Anybody have any ideas?
All computers running OS X 10.10 or 10.10.1.

It's possible that your work network is blocking some of the ports necessary for B2MM to work.
Have you ever tried accessing the Mac mini from a different network outside of your home? If this works, then it's probably specific to your firewall/network settings at work.

IChat crashes with EXC_BAD_ACCESS (SIGBUS) when attempting screen sharing

I seem to have an unstable iChat on my 27 inch i7 iMac since early January when it replaced a 24 inch model where iChat worked well.
I've been reading various helpful posts and tried things like trashing the plists, set my speed limit to 500kbps, running in 32 bit mode.
I use screen sharing to support my elderly mother and some of her equally elderly friends who I have converted to mac but it's getting terribly frustrating since I cannot reliably connect for screen sharing and end up having to drive for 2 hours to sort out basic stuff. The most recent crash is EXCBADACCESS (SIGBUS). I'll post a short extract below. But I've also had other errors (SIGSEGV).
I've now discovered that I get the same failure about half the time when testing in-house both connecting over the internet and via Bonjour to a new 15 inch core duo MBP both machines running 10.6.2. Any ideas please? Sometimes it works, sometimes it doesn't.

Hi,
It does seem that is a specific build.
10C refers to 10.6.2 as a range of builds
The numbers after that are normally 3 digits long and yours is 4
Those people that sign up for the Developers copies tend to get minor/text update as testers along the way which is why a General Release version tends to be a specific number. (In this case 10C540)
There are other things we could try that may help.
Try Launching Disk Utility (Applications/Utilities and Setting the tab to First Aid then use the "Repair Permissions" button.
Also try a PRAM reset.
Shut down the computer.
Restart it holding down APPLE(or ⌘)ALT(⌥)+PR Keys until you have heard three Start Up Bongs.
Do them one at a time and then test iChat.
After this we will move to deleting ichat .plists and forcing it to rewrite them from defaults.

IOS - Performance issues when touching screen

Hello,
I am having perfomance issues when the use keep moving one finger on the screen.
I am testing with :
- flash builder 4.7 beta 2
- air 3.5 (beta too I guess)
- iPhone 3GS running on iOS 6.0.1 (also tested on an iPad3, and even though it's less horrible, the impact is still huge compared to what you could expect).
- gpu mode
- always published as an addhoc release build (best)
Test 1-A) :
- Have a completely empty project, add a fps counter (with mouseEnabled and children false).
- run a while each frame so you force the fps under 60 (if not you won't see it going down from let's say theoric 100 to theoric 70 since fps max is 60).
like this for example :
                                        protected function framingMouseTest(e : Event) : void {
                       var t : int = getTimer();
                       while (getTimer()-t<30) {}//this will keep flash busy
Notice that when you keep your finger on the screen and move it you loose approximately 7ms per frame. (for example from 26 to 22fps or from 48 to 36 fps, depending on the time waited in your while).
Test 1-B) do the same with even stage mouseEnabled false (and you could even set it + mouseChildren off recursively from stage) : same result (-7ms). Why ? Since it is all off it shouldn't take more than 1 ms no ?
Test 1-C) add Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT; Same result (found some threads saying it would help but not that much...)
Test 1-D) Multitouch.mapTouchToMouse = false;          It is a bit better but still around 5ms (didnt write down this one)
Test 1-D) Multitouch.mapTouchToMouse = false; Multitouch.inputMode = MultitouchInputMode.NONE;          It is a bit better but still around 4ms (didnt write down this one) And you have now nothing left to remove I think.
Now the horrible part :
Test 2-A)
Add some clips and subclips to your scene, containing bitmaps, results may vary depending on how much (let's say 30, I don't have the exact count on subcontainers), etc. but what's important is the difference between no finger and 1 finger moving on screen.
On normal conditions (keep some mouseEnabled for the clips you need interaction add those a listener, lets say 10 total, default values for the rest) you can get about 40ms per frame down ! (for example from 36 to 14 fps) just by touching the screen.
Test 2-B) Recursively set everything to mouseEnabled and children false after everything is added, you still get about 30ms down because of the finger, whereas it shouldn't test above the main container which already has mouseChildren false.
Test 2-C) Multitouch.mapTouchToMouse = false; Multitouch.inputMode = MultitouchInputMode.NONE; you still get about 20ms down !!! whereas you're in a mode when touch and mouseEvents shouldn't even exist.
I am really confused. My conclusions are :
Performance are really impacted whatever you do when a user touch the screen + it will get worse the more clips/depth you have. Even if everything is made to disable this.
I think anyone could test this with pretty much any app done with AIR on iOS, as long as the framerate is already <max (<60 for example), touch and move your finger and tell me what happens regarding framerate.
What I would love :
1) tell me what I am missing if you think this is due to some mistake on my part, if not :
2) better perfomance when containers have mouseChildren false. It seems obvious it still takes longer to process.
3) a mode where the touch/mouse is REALLY disabled including stage etc. It is quite obvious air does takes longer to handle touch as the scene gets more complex, even if you disable it all (seems to work only 20%...)
4) a mode where the touch/mouse is REALLY disabled, on anything but the stage. Because you might want to handle everythin just from stage coordinates, if your project allows you to, like mine. Unfortunately right now it wouldn't give you enough performance boost (well, a bit but still maybe +20ms).
PS : you don't even need to add mouselistener or touchlisteners (tested both), but if you do, it is worse.
Compared to this, I am finding rendering performance pretty decent - even though it's tough for a game on a 3GS- as long as you do it properly.

Could you open a bug report on this at bugbase.adobe.com? Please include any sample code or applications so we can quickly reproduce the problem. If you'd like to keep this private, feel free to send them to me directly ([email protected]). Also, please note in the bug if this is new behavior with the latest AIR sdk or if you've seen this in past versions too. Once added, let me know the bug number and I'll follow up internally. I've alerted the iOS team to expect this bug.
Thanks,
Chris

Back to My Mac - Screen Sharing Mac OS X 10.10 problem

Sense Mac OS X 10.9 great feature Screen Sharing & Back to My Mac does not works any more.
Mac OS X 10.10.1
Russian interface:
We can see remote computers, but can not connect. We get a error.
English interface:
We can not even see remote macs.
If I start up main computer from Mac OS X 10.8 Screen Sharing works fine. Remote macs has Mac OS X 10.8 and 10.9

I have the same problem, just today (although I'm still running 10.6.8). Every morning I turn on my main Logic mac then fire up my 2 slave macs, connect to them, activate Screen Sharing, and get going.
This morning I tried it, connected to the other macs as usual (I can see/access/alter their hard drives from my main mac) but when I click "Share Screen" I just get the "connecting" dialog box & it just keeps going.
The weird thing is, when I put my laptop into the network via wifi, I can screenshare my main mac's screen (all 3 of them, actually!) but not my 2 slave macs that are ethernet'd to the main mac.

Back to My Mac / Screen Sharing

I am trying to (and have had sporadic success with) controlling my desktop computer (at home, iMac, OS X 10.10) with my laptop (via Internet, Macbook Pro, OS X 10.10.1) through connecting through Screen Sharing from the Finder window's "Shared" computers. It's really hit or miss whether the iMac shows up in the Finder window, and I can't figure out why.
I've been all over websites and forum posts for information, and have learned a lot of things, but many of them are outdated. Here are some things I've done/learned about:
I can always log into my iMac through Chrome Remote Desktop, but I want the functionality of Screen Sharing.
I cannot simply start the Screen Sharing app and type in my icloud id, because that only allows viewing and not controlling the screen.
SSH through the terminal is hit or miss; it works more often than Screen Sharing does, but still not 100% of the time. I use it to copy files, but most of the time I need to be using the GUI.
A couple times the iMac showed up in Shared computers right after I did something, i.e. trace route to icloud.com or initiate a Screen Sharing session from the iMac, via Chrome Remote Desktop. Other times I've tried to jumpstart it like that and it doesn't work.
I've tried a variety of networks (home networks, workplace, mobile tethering) and I get different results every time, on every network. I might see my iMac in the Finder at work one day, and the next day it doesn't show up now matter what I do. So it must not be blocked ports in every case.
I've been taking notes almost every time I successfully connect, and I have documented cases where I can get it to work by (once again) going into my iMac via Chrome, disabling Back to My Mac and/or Screen Sharing, then re-enabling them. But of course, this hasn't worked consistently.
Any help or insight is appreciated. Again, this is all purely done over the internet, as accessing my home computer over a local network is of no use to me; I'm physically separated from it most of the time. (Most articles and walkthroughs teach people how to do it with their 192.168.x.x addresses, and they assume that your computers are always in your Shared section in Finder. This is not the case for me.)

That means that the Remote Management is turned on.
All you have to do is turn the Remote Management off if its not in use.
You may want to investigate how the Remote Management is being used to make sure you are not turning something off that needs to be on.

Launchd cancels logout/restart and kills app when using screen sharing

I have an app I want to always run so I created a LaunchDaemon to keep it going:
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.sns.sentinel.air</string>
<key>KeepAlive</key>
<true/>
<key>ProgramArguments</key>
<array>
<string>sh</string>
<string>/Applications/oc4j/restartSentinel.sh</string>
</array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>
And restartSentinel.sh is very simple:
echo Process Sentinel.app is being restarted...
open -W /Applications/oc4j/j2ee/home/applications/Sentinel/Sentinel.app;
Everything seems to be fine but I have to access this machine via screen sharing. Then when I log in, the app gets shut down and only restarted a few minutes later. Also, when another user logs in, they are not able to log off. Launchd seems to cancel the restart.
I do also have two other plist files running other things but they seem to work okay (they don't crash, but the one which needs to be kept alive (code is almost the same as above) also seems to be preventing log out for users other than me).
So how can I get launchd to let people use screen sharing without killing the app and how can I get it to stop canceling logot/restart?

Try the Unix forum (not thread) under OS X Technologies.

Password "wrong" or irretrievable when using Screen Sharing

Strangely, I tried using Screen Sharing on the finder to access my iMac from my Macbook today and was asked to enter my password. I presume that this is my system password that I use to log in to my computer. It is the same for both. However, no dice...
Furthermore, I can't find this password in Keychain...also to no avail. I have no idea how to get things right so that I can access Screen Sharing.
Thanks in advance for any ideas you may have.

Start with Finder->Help->Mac Help->search for *Screen Sharing* and peruse the many hits.

Double-NAT when iChat "Screen Sharing"

I have a weird situation, wondering if all you super-network geniuses could offer an opinion...
My current setup:
-DSL Modem hooked up to a Time Capsule.
-Time Capsule in Ethernet Mode & "Share Public IP Address: NAT & DHCP Enabled."
-Time Capsule has a wireless 5Gz "N-Only" network.
-2PC's, and an Airport Express connected to N Network wirelessly.
-Airport Express "Extends network" via ethernet cable to Slingbox & TiVo (via switch.)
-Airport Extreme wired to Time Capsule.
-Airport Extreme in Bridge Mode.
-Airport Extreme has a wireless "G" network & USB Printer.
-Airport Extreme network for "iPhones & G computer."
-Only Port Mapping is for slingbox, ports 5001,5001.
O.k. Everything works PERFECTLY! Except when I start a "Screen Sharing" session in iChat AV.
When I click "Ask to share xxx's screen" It says "Waiting on xxx" and then Airport Utility pops up, saying that the Time Capsule has an error - "Double NAT" and I'm off the internet. All I have to do is select "Restart Time Capsule" and after a reboot, I'm back in business, and all is well again. I can screen share, chat, etc. However, if I try and start "Screen Sharing" again, same thing - Double NAT.
Do I need to enable a Port Mapping for iChat?
Any suggestions or help would be greatly appreciated. I thought I finally had the network thing down, but this one little thing keeps making me reset my router. (Doesn't seem like the Apple way.)
Thanks.

I have the Time Capsule set up as the DHCP server, distributing a shared IP address.
The Express is set up to "Join and existing network."
I only have 1 Extreme and it is set to "Bridge Mode."
The Time Capsule is the router hooked directly to the DSL modem. It is in "Ethernet" mode, and I'm not quite sure how to check the little DSL modem's settings.
It's so strange, that only this one little request, "Ask to share xxx's screen" does this error occur.
Looking at more settings on the Time Capsule, under NAT settings, I do NOT have the "Enable default host at:" option checked, and the "Enable NAT Port Mapping Protocol" IS checked. Under Port Mappings, 5001,5001 is the only item for Slingbox.

How to resolve password issue when attempting file sharing?

I have an Imac with os9.2.2 and a ClamShell ibook with os8.6. Until recently I have been able to file share, using an ethernet cable, without using a password.
When I go into Chooser on either machine and click on file server, eg. "Imac", I get a message to effect that the password is not recognized. I have tried to create a "new" password, but I cannot provide an "old" password.
How do I get around this or create a new password and move on?
Any help would be appreciated.
Imac Mac OS 9.2.x

Go to the Users and Groups tab in the FileSharing
control panel on machine number one. There you (as
the 'owner') will name the permitted User(s)—whatever
name you want to use— and you'll give him/her a
password—whatever you like or nothing at all.
Do the same on machine number two.
Since you own both machines, you can erase any
previous users with defective passwords. Or just
change their passwords.
If the Owner of each machine is the very same name on
each and if you haven't established a password for
the Owner(yourself), then you should be able to log
in as the Owner w/o a password. Presumably this was
what you had. Did you change the owner's name on
either machine?
If you're not worried about security, letting Guests
have access could also be password-free.
Ed,
Thank you for your help; file sharing is now operating between those machines.
I have now added another computer(OSX Tiger) to the network.
I am having similar problems getting file sharing to work. The new machine is owned by my wife. I added a name for her computer in the Users and Groups on the 9.2 machine. Her machine seems to recognize the old machine. But when I attempt to connect from either machine I get the "cannot connect" message.
Apple Help for the new machine suggests that a connection can only be done from the 9.2 machine.
Any suggestions? Perhaps this is not fair to add another question. Let me know if you would prefer that I post a new question.
Thanks again.

Is it a hardware and/or software issue when the screen suddenly shifts?

Hey there,
Yesterday my 2.5 year old laptop had an error.
I was working in excel, when suddenly the screen shifted out of focus.
I saw everything on the screen echoed some pixels to the upperleft, and moving the mouse over a shifted area turned this area back to normal, however this also shifted the area where the mouse no longer was.
I thought I should reboot my laptop, but then it wouldn't start. I have tried rebooting in safe mode and recovery modes and saw several blue screens flash by. I have inserted the 2 recovery discs that came with the laptop, but it cannot finish installation.
What concerns me is that even if I get a recovery disc to work, the screen might still be shifted. Do you think this might be a hardware error, a cable breaking somewhere? Or is it a software error somehow? Or perhaps it was a software error leading to a hardware malfunction?
I'd like to install an operating system again, but if the screen has a hardware issue it might be more worthwhile to buy a new laptop all together.
Please advise if you have any idea on what could cause this, thanks in advance!
Kind regards! ^_^

Hey there,
Just wanted to let you know what I learned. I visited some computer repair shops. The screen was acting so weird, I had no idea what it was called, but now I know the screen was garbled. It was a hardware error, namely the chip of the memory of the graphics card was burned, and apparently since it is directly connected to the motherboard it would be an expensive party to have that repaired.... I ended up buying a new notebook, this time with 3 year's insurance ^_^ What was also interesting is that when we installed older operating systems on it, with very low resolutions, everything worked out fine. As soon as the newest graphic card driver was installed or we switched to a normal resolution, it was garbled again. It was definitely the memory of the graphics card.
As a suggestion, I think it would be helpful if the term 'garbled screen' or 'garbled' is a searchable phrase on this website, because it took me forever to find out what the problem was called. There is some information about screen issues, but only if the screen is black or blue screen of death. If more people experience this garbling issue, it might save some headaches :p
Thanks again for everything!
