OS X V10.7 Lion :: Sharing Error When IMac Awakes From Overnight Sleep
Jun 1, 2012
Every few days I get this error message when my iMac wakes from sleep. The error is "The name of your computer (my computer name) is already in use on this network. The name has been changed to (new name). I must then go to Sharing and change name back to the correct name. My local Apple store advised me to go to Recovery and download new version of Lion. I did same, but this action did not stop the problem.

Macbook pro 2.16 C2D
iMac 2Ghz C2D
Both running 10.7.3
I am trying to connect from my macbook pro to iMac by using remote management with allow access for All Users but cannot get to connect from MBP to iMac. I can connect without problems from iMac to MBP. The macbook pro just sits trying to connect.
I check the log on the iMac and see the new entry appear during connect attempt of:
3/31/12 7:14:55.979 AM ScreensharingAgent: [CL_INVALID_DEVICE] : OpenCL Error : Failed to create context! Invalid device
Firewall turned off on both machines.I have created a new user on the Macbook to see if that could be the solution but still same occurrence.

Often I just put my Macbook Pro with Lion OS to sleep manually, instead of shutting down. Since the upgrade to OS Lion, when I return to the computer I often am greeted with a message that I could not be logged out because Firefox failed to quit. Is sleep a logout? I don't intend to logout...though I do require a password to regain access after the computer enters the sleep state. This is a consistent issue with Lion, which never occurred with the earlier OS.

I have an IMac running 10.7 and G5 running 10.5.8 the G5 we are using as an in house server. It working fine for 5 months then our internet went down and now it no longer works. This is how I have it set up. on the g5 I have file sharing turned on and the folder I would like to share set to share. Then I made logins for for the computer I want to share the folder with. The on the IMac I would go to connect to server and the g5 would show up then it would ask me to login so I did. Everthing worked fine but now when I try to login it just gives me the spinning wheel but never logs in why is it doing this? I have restarted both computers and I have deleted my login and re added it. But still the same thing.

After updating my new iMac to 10.7.4. My internet sharing suddenly doesn't work any more. I connect my ipad and iphone via the wifi. It will drop out after a very short time, about 10 seconds of Facetime, so I turn off the wifi, then the internet sharing then reboot everything but nothing seems to work. It worked perfectly in 10.7.3 but now I can't use the internet on my ipad.

I am running an iMac G5 Version 10.5.6 (Leopard) and I have activated every security feature I can find.
I have disabled all sharing, I have disabled guest access, I have the firewall up allowing only essential services, and I am in stealth mode.
In spite of this, he is obviously able to see every website I visit, and I am afraid he can view my email or the court documents etc. on my machine.
When I click on my harddrive icon, I can see his machine, listed as PC server, under 'sharing', even though I have disabled all sharing!!
There does not seem to be an option to disconnect him, or block him.

If I have file sharing turned on on my macbook pro retina (late 2013 model) I cannot put it to sleep at all. The manual sleep option from the apple menu does nothing apart from dimming the display. The computer stays on. This is plainly a bug.
Steps to reproduce:
turn on network file sharing.
have a client connect to your mac (he does not need to stay actively connected and using filesystem at the moment of sleep attempt).
Then choose sleep from the apple menu
result: no sleep.

When my IMac goes to sleep, the screen saver is "frozen". The only way to get to my login accounts is by "cleaning" the screen with my mouse. It's as though the screen is not refreshing itself after going to sleep and whatever the last image was, it stays. However, it's not locked up or anything. I just need to move my mouse around over the login accounts and it slowly clears away the screen saver so I can see where to click to log in.I've tried disabling the screen saver, but have the same results. Something is causing the last image to freeze on the screen when the monitor sleeps.

Ever since I bought and downloaded OS Lion, whenever I put my mac to sleep or it goes to sleep on its own it occasionally won't wake up from sleep. It has to be manually rebooted. Is anyone familiar with this problem. Apple must know about it by now. I'm not lugging my 27" iMac into the apple store to have them look at it unless it won't reboot. Hoping it doesn't come to that...anyone familiar with this or have ideas on how to fix it? I don't know if it's a 3rd party software issue or just the OS.

Retina Macbook pro, late 2013 model, Mavericks with all updates, won't sleep if file sharing is on, and if clients have connected previously (not necessarily actively connected at the moment).
I choose "Apple menu" - sleep - and all it does just dim the display. The computer remains on. This is plainly a bug, since manual sleep should work regardless of any other condition, e.g. networking activity, etc. I can understand auto sleep delay with file sharing on, but even that must have an option to override network activity wake. So the bottom-line is that I cannot put my mac to sleep at all. I do not cover the lid since I use it with external display.

I have my xbox 360 connected to my macbook through ethernet. On my mac i have internet connection sharing enabled from airport to ethernet. Everything works fine apart from the xbox saying I have a strict NAT.
I made sure the ports were all configured to work with my router, and UPnP is defiantly enabled on my router. I even tested to see if it was something to do with my firewalls, but even with them turned off, I still get this NAT error

Installed the update and what wasn't a problem is now a problem. The computer will not connect to wifi without me telling it to after coming out of sleep. Was not an issue with 10.7.2.

I leave it to render with After Effects CS3, and when I come back, it is frozen! I have to shut it down by holding down the power key and start it up again. I have Leopard on this, Tiger never acted this way?

I have my macbook (2.4 GHz Intel Core Duo 4GB 667 MHz DDR2 SDRAM Mac OS X 10.5.7) set to auto restart in the morning. This morning when i went to check it out it didn't restart due to one of my applications running. I'm not sure if this has anything to do with the problem but still. There are several problems right now... I'm going to try and explain them all because i really want to get this solved
1) I haven't been able to restart or shut down my computer the "soft" way, it usually works but today I've had to hold down the power button for a hard shut down every time i want to restart. When i click shut down or restart it drops all the windows like its going to shut down but then it just stays at the point where my desktop is up
2) For some reason firefox wasn't loading when i clicked the application button, but safari would. I'm not sure if any other programs were affected but i re-downloaded firefox and it works again.
3) The computer it self is unbelievably slow, simple processes like copying files takes much longer, time machine stays at the "preparing" stage forever. Sometimes when i try to copy files to my external it works fine, but other times it says that parts of the files are missing and it can't copy them.
One of the solutions i read was to create another account, i did and it seems to be working at a normal speed but i still cannot shut down. I don't have the boot CD and would really prefer to keep my regular user account than the new one

When I begin the job, the CPU monitor indicates they are working hard, the fans come on and the machine gets hot...all indications it's doing the job.However - if I set it up to do the job overnight, when I come down in the morning the computer is asleep and stone cold, which suggests to me it has ceased processing the file.
f I wake it up - it resumes processing, getting hot again and so on.So how can I ensure it continues the job overnight? I've tried setting ' Never go to sleep ' in system settings ( screen still set to go to sleep ). That doesn't seem to work. When I set it to ' Never go to sleep ' in system settings, do I need to restart to make the settings active ( if I restart I lose all the work on the CAD file done so far! ).

This was a new battery 8 months ago. I checked its health periodically and all seemd good until two days ago when the battery went from healthy to dead in less than 8 hours. Is there anything to do to bring this one back to life or is the only remedy to buy another one?

I changed the username, passwords, background, settings, name of the harddrive and all that, but left her music and photos on for the time being. Then I turned it off for the night. I remember something popping off before it turned off, and I think it was just saying changes had been made or something like that. And I THOUGHT I had pressed okay to save those changes....it was late. But I turn it on this morning and it's practically gone back to basics. EVERYTHING is gone...no music, no photos. The settings and background are factory status. iTunes, iPhoto, and iChat are responding like I'd never used them. The only thing that stayed was my user name, the photo, and the name of the hard drive. I've looked through the computer and havent found anything. I couldnt have restored it, could I?

I have my main Mac in my bedroom. I like having it announce the time during the day but at night it wakes me up. I can manually turn it off at night but sometimes I forget. Is there a way to have it automatically turn off the Announce Time feature overnight and then automatically come back on in the morning?

I just switched from a PC. All my backup (files, music, photos, etc) are stored onto a Windows-formatted HDNow i have error when i try to transfer them over
It gives me the error-36did a bit of research but none of the remedy worked (i.e. terminal>dos_clean)I have previously transferred files from the same external HD onto my macbook in which i purchased last year and don't recall having any problems. (although not all the files were transferred onto my macbook, only a few files in which i needed) What can be the alternatives for me to transfer all my files over onto my imac without having the reformat my external HD?
