OS X :: Using Jumbo Frames & Screen Sharing / Panic
Mar 11, 2008
Macbook and Macbook Pro both running 10.5.2 - both exact same specs. Connected through Gigabit ethernet using a Netgear GS108 switch that supports Jumbo Frames.
When I set the frame size to 9000 on both computers and then screen share, both computers Kernal Panic.

Whenever I try to use Screen Sharing to control this one particular Mac Mini, and someone else is using the mini, and I pick "Connect to Virtual Display", I get dropped to a grey linen screen. Like the login screen, but without a list of usernames or anything. There it sits. Here is what I see in the console of the mac mini when I try and use a virtual display from the other machine:
3/10/12 7:30:04.291 AM mds: (Error) Backup: Couldn't stat source path '/Users/glados/Library/Saved Application State/com.apple.finder.savedState/window_3.data' -- importing from backup path instead

My daughter has dropped her ageing MBP, bent the screen lid and now the screen is no longer usable. We have other Macs available to access the data on the screen if we could turn on Screen Sharing on the damaged MBP running Snow Leopard.

My 3+ year old MacBook is unable to startup anymore. Whenever I boot up, after the apple logo I get the Kernel Panic. This happened after one time when I forced shutdown after I thought my macbook crashed. I've read from past threads this is possibly to do with hardware problems, but I can still boot to bootcamp windows (which I am currently using) and all seems to work fine. What can I do?

Does anyone know of a way to enter full screen in Mac OS X's native screen sharing application? I recently purchased a new MBP and wanted to screen share to my old MB with all my "junk" on it. It would be handy to actually enter full screen as opposed to being restricted to a window sized screen.
If this isn't possible, anyone have a good recommendation for an alternative application?

i have been having issues with mac users who have the new mac book pro with the retina display, apparently the native screen size is too large for the web ex and logmein services to display. they are currently aware of the situation but there is no resolution date, is there any way to lower the resolution. we tried to have some peopel lower the settings but there is no resolution setting where the user can lower it to a much smaller size like 1024 x 768. the web ex app is usally ran through java.

I think it's UNIX. Not too familiar with it. I have G4 powerbook. 4 years old. Tiger. I was surfing safari, when I got the wheel. Couldn't even click the desktop to activate the finder. Did a hard reboot. Now, the mac Icon comes up, then goes to a black screen, then to the MAC OSX start up window (bar doesn't move). Then a black screen with Darwin/BSD (new-host.home) (console) login: It just comes up with a line that ends with my user name and restarted then same thing happens.

I turned up one day to teach using the Mac Pro and the message on the screen said I had to restart my computer. After many times I gave up. I wrongly thought the hard disk failed as one of the pupils saw some water underneath the Mac from the leaking roof. I checked and formatted the hard drive inside a pc and put Windows on it. After inserting the hard drive and the OSX into the dvd drive proceeded to re-install the software, only to find exactly the same problem as before. What to check next before trying to find someone to fix it.

Last night I was defraging my G4 OS Tiger 10.4.11 and at about 53% the power went out. Now all I get at start up is the Kernel Panic screen. What should be my first step?

Last night I was in the middle of downloading a file and had a kernal panic (crash report below).When I now log in I either immediately get a black screen ( but can see white spots which are the corners of windows opened) or sometimes I get to my desktop but after a few minutes the screen windows deteriate (repeatative ghosting like an old 80'spop video!) which then become unresponsive. I'm figuring it's had it's day now and hope to get a new iMac tonight. I would like to migrate everything but am unsure whether this is a hard drive failure ( in which case the migration is probably out of the window) or something else?

i have a Macbook running mountain lion, which froze today on safari. I had to force close then when I restarted, it stuck on the grey screen with apple logo and pinwheel. I tried rebooting in safe mode, which eventually came up with the following
panic(cpu 0 caller 0x004384FF): "unable to find driver for this platform: "ACPI".
"@/SourceCache/xnu/xnu-1228.12.14/iokit/Kernel/IOPlatformExpert.cpp: 1407
and a lot of other stuff under that. I understand this is a kernel panic?
i've tried a disk repair which came back as 'disk utility can't repair this disk etc'
is there any hope I will be able to connect via Ethernet to another mac and get to my hard drive or is all hope lost?

I am stuck with DOS-looking commands on the gray apple startup screen. Part of the commands are listed below. I can't do anything. I'm not even sure I've been able to reboot, although I've tried holding the power button, holding S+Cmd+power, and holding ctrl+option+cmnd+shift+power. I can get it to go dark like it's rebooting, but the gray apple screen pops back up and about 3 seconds later the codes come back.

Something weird has happened twice in the last week or so - I close my MacBook (black), open it later (I think both times I moved it somewhere), and when I re-open the screen is black and I have to restart using the power button.
What I noticed this time is that I could barely make out text on the screen, and although I couldn't read the whole thing, it was definitely a kernel panic "grey screen of death":
I'm wondering why this could be happening - both times it definitely had to do with closing and re-opening the laptop, and I'm wondering what the dimmed screen (I could barely make out the words) says about the issue.

my macbook pros been bringing up a restart screen when i turn it on for the past week. Im running snow leopard. when it does turn on after a few tries, it ends up having a flashing screen after 10-15 minutes and freezes. and my mouse will be super sensitive, but i cant click anything? ive never had a problem until this. I've ran the little hardware check you can pull up from boot and nothing came up.
heres my error message:

How can I change the quality of screen sharing in Snow Leopard? I've tried adjusting defaults write com.apple.ScreenSharing controlObserveQuality but I'm having no luck. It always streams at full quality which leads to painfully slow screen refreshes.

I want to set the screen sharing on a iMac. It works fine when I enable the "Anyone may request permission to control screen" but I would like to use only the "password" option but it doesn't work. When I just set a VNC password and then try to connect via the "Screen Sharing" app, it keeps saying that the password is not correct. Which "login" am I supposed to use? When I use another client such as UltraVNC, it works. So how can I enter a password onl with the Screen Sharing app?

I've gone into settings and turned screen sharing on. I've turned the firewall off. I've put file share on. I've tried everything. I tried to start a screen share with my friend and it started to go but then said that an unknown error occurred. is there anything else I need to change to it?

Any recommendation for a free app to control my PPC (runing Tiger) from my MBP remotely? Screen Sharing on my network is a snap but that does me no good when I'm away.

Just got a new MBP and migrated my account from my MB using Migration Assistant. Everything works, but if I try using screen sharing/Back to My Mac from ANY of my other Macs in the house to my new MBP, I cannot log in using my short name.
Can log in and screen share using my full name, but prefer three letters over many. Everything else works fine; can even file share using short name, just not screen sharing.

Question: What is the point of telling Screen Sharing to "Remember this password in my keychain" if every time I go back to use it I have to retype the username and password?

I've been using my MacMini as a server to backup and sync several Macs on my local LAN but recently I found the need to access certain files outside my LAN. That said, I set my router to forward ports 548, 9, and 5900 (file sharing, WOL, and screen sharing, respectively) to my MacMini. This has actually worked rather well for me -- other than WOL. So in an attempt to diagnose the WOL issue I started probing my router's incoming logs (to see if I can successfully send a WOL magic packet from outside my network) and thats when I noticed a few random IPs probing port 5900. So my question is, what are some security measures that I can take in order to prevent someone form accessing my MacMini from the open ports? In theory couldn't a simple program attempt to repeatedly connect to a port and brute force a password? Excuse my naivety with networking, but I'm a little concerned. I did some searching but I couldn't find anything substantial on the forums.

I am thinking of getting an MBA as a second computer. One thing I am interested in, particularly after discovering how slow it is to access a remote drive on the AEBS, is screen sharing significantly faster?
1) If I was at home screen sharing from my MBP, would it work pretty much in 'real time'?
2) Same question but when on the road.

I know that Leopard has a screensharing utility built in (in the coreservices folder) or by going to Go>Connect to Server>vnc://---------- in the Finder menu, but I would like to know what IP I type into the box (I would like to share with someone not on my local network). I'm not an expert in networking, but I'm pretty good with computers, so you can use technical terms.

So I bought a new Mac Mini today to be used simply with my TV. I hope to control the Mini through Screen Sharing but I have ran into some problems.
First, I do not want to purchase a keyboard and mouse because I will never use them. However, is it possible to setup the mini without it. As of now I am struggling to even bypass the mouse installation screen.
