Leopard hard crash on Network Location change

When I try to change my network location from the Apple menu, occasionally (like once in approx. 20 changes) Mac OS will crash. It's a hard crash, meaning no menus, no mouse, no nothing. It just simply and fully hangs, and I have to hold the power button down to restart. These seems pretty harsh and I almost never crash.
Generally speaking (though not repeatable) it seems to happen when I come into the office, after having been on my home wireless network. shut the lid, go to work, flip it open, Mac automatically jumps on work wireless. I then go to apple menu > location > choose the LAN wired network and that's when it hangs.
On a MacBook Pro, 10.5.2. Wireless at home is 802.11g, same as work.

Hi Gary;
This is a problem that has been ongoing, no relief yet. Here's the latest and second thread that David Villeneuve started that might give you more info if you haven't already found it.

Leopard Hard crash and airport disconnect

Hello alll
I have done a erase and install with leopard on my macbook pro 2 twice now thinking it was a installation issue.
My internet connects through a netgear router that worked 100% perfect when on Tiger, but now after random intervals i lose connection to it even though it shows it is still connected to it... i have to turn airport off then on again which sometimes works or i get the screen of death and have to hold down the power button to reboot...
Really hope someone can help
James

Sadly I would love to use this Back to My Mac feature but the problem is staying connected to the internet not using a feature, I'm up to date on software updates and router is on the latest firmware.
So my router is supported but isn't staying connected to the net

Network location

is it possible to run a script based on a network location change.
i have a macbook, when i am working at my desk i have it configured to use a wired network, when i move from my desk i change my network location so it starts the airport and connects to my wireless network, this all works without problem. however what i would like to do is disable time machine so that it will not attempt to backup over a wireless
thanks in advance,
steve

The only other thing that I could recommend is write an applescript. You might get lucky and find a script already written. I have not written scripts for many years so I can't help you out there. When finished, you can place it in your dock and use it to switch back and forth.

Textedit and preview crashing in osx lion when changing network location

I did upgrade to lion on launch and noticed that textedit and preview work quite well except when changing network location: after a few seconds of spinning ball, both crash.
Tried repairing permissions, deleting "containers" folders in my library and so on, without luck.
Anyone is experiencing the same problem?

UPDATE 2: I'm having this issue both on my iMac and my Macbook, so I suppose it's a lion bug and not simply something related to something that went wrong during the update (permissions or something like this). It's both in 10.7 and 10.7.1.
I'm going to try on my wife's Macbook to see if it's something related to some software or setting I'm using; in the meanwhile, can someone out there try to reproduce this issue? Just open textedit and change the network location from the menu bar (you should create one other than "automatic" for "locations" to show up just below "dock"): at this point you should get the spinning ball and then a window telling you that textedit just crashed. Try to do a couple of times if it doesn't crash the first one.
BTW I noticed that textedit doesn't crash if you have the network preference pane open and active ("system preferences" showed on the menu bar) and change the location from the menu bar.
I think I'm going to give a call to Applecare to see if there's some plan to get this corrected in some next update.

Crashing changing network locations

I get a system crash every time I change my Network Location. Is this a known problem? I am forced to pull the plug to reboot. This only seems to happen if the computer has slept. Until then the Locations prefpanel works fine.

Repair permissions on your disk from the Mac OS X install disk.

Have recently acquired an additional black MacBook, and installed Snow Leopard onto it. Trying to get it to connect via a plug-in USB wifi unit (poor reception on Airport) I have an extra Network Location which does not work. How can I remove it?

Need to get a second hand black MacBook connected. Poor reception on Airport so tried a plug in wifi aerial. That didn't work, but now have a Network Location I can't get rid of. How do I remove it ?

Hello my ginger,
I tried what you suggested - but to no success. The problem came up when I was re-entering the new settings. If I left it as using DHCP it would run for a few seconds with no IP address, then drop in a 169.254 one which would not connect through. To overcome this I tried using the 'Using DHCP with manual address' option and entered in an address which it had set up from the clone boot. This appeared to be okay. When I then tried renewing DHCP lease sometimes that address held. When I tried connecting though - no sight of the internet, and the exclamation mark was across the wifi icon in the menu bar. If I switched it to Using DHCP it would randomly fall back to the 169.254 address.
The only significant differences I could see when cross checking all the settings info was in the WINS panel the NetBIOS had a slightly different configuration of the name - but as they ended in the same numbers I assumed they were the same. And, when looking under Keychain Access, in the System section list (it also appeared in the login section) additional info box they had different locations - 28 characters in four groups. I don't have a clue what this refers to. Also the allow access list in the boot clone included System Preferences, but did not in the Snow Leopard boot, so I added it in. With no success.
I am so frustrated I am thinking of giving up. I seen have loads of postings on the net about a variety of problems with wifi connection on Snow Leopard. I have version 10.6.3. Did it get any better in later Snow Leopard ? Or in any of the OS s after that ? It was always so easy and so solid under Leopard - why the h**l did they change it ?

Timemachine & network hard crash

I'm wondering if anyone else is having something like this happen. My mid-2010 macpro is hard crashing about once a week when time machine is backing up. I figured out it was during time machine by looking at the kernel logs and seeing that the logs stopped after time machine launched, but I just caught it right now when it crashed.
I hadn't been using the laptop for a bit and went to refresh my email -- which said it couldn't reach the server. I noticed that the time machine icon was spinning and that the wireless network icon had no bars. I opened the drop down and it showed no networks available. I was about the turn netowrk on/off again when the laptop just went dead. Black screen, no response. This is how I usually find it.
In the kernel logs, I see something about airport ink down ("Reason 8 (Disassociated because station leaving)."). The last message is "IOSurface: buffer allocation size is zero"
The backup drive is a network drive attached to my mac mini (the mini is set to never sleep, but the attached drive will auto sleep).

Changing Network Locations under a restricted/managed account.

I am an IT administrator at a company that now has OS X Leopard laptops that are being used both on our network and outside our network. The user has a restricted account but does not have Parental Controls enabled. The restricted user account can not change locations with out supplying an administrator password. Is there a way for a restricted user to change their Network Location (it works in Tiger)?

The account is not an administrator account. Therefore they do not have write access outside their home directory. The effect of that is they can not install applications and can not change some preferences.
+..."In 10.5, as in earlier versions of OS X, switching between pre-configured network "Locations" via the "Apple Menu" should not require authentication"...+
I have not looked into changing Locations via the Apple Menu, only through the Network menu in System Preferences. I'll give that a try tomorrow morning and get back with you.

Running Mavericks OS on MacBookPro...had some hard crashes past 24 hours...forced reboots....now can't print anything from Office or Firefox. Both crash during print dialog - changing printer causes instand crash. My system printed fine before the crashes yesterday. I can print from the Stickies app and safari printed fine. I did a full Shutdown/restart and that didn't work. Ideas on how to get PPT files to print again or print from firefox??

Server 2012 R2 - Change network location from public to private

I am having an issue with changing Network location to private from Public on Server 2012 R2 X64 .
Please note all the reference for previous servers for fixing this issue does not work on 2012 R2.
I am using Static-IP and "Workgroup" as domain setting.
In 2012 server by Right clicking on Network and Turn sharing on or OFF worked but in 2012- R2 Right click is not working not providing turn sharing ON or OFF option.

Check if you can change from here :
Run -- Gpedit.msc-- Open Computer configration -->Windows Settings -->Security Settings -->select Network list manager policies

NO it did not work I had already tired and rebooted it does not work. Just for other having the same issue please note my Build is 9600 so this may not apply to you,if you have a different Build you might not have this problem.
I am going back to server2012 rather using R2.

How do you change network location type on Server 2012?

Within Network & Sharing Center there appears to be no options available to change a network type as you could do in Server 2012?
Within Network List Manager policies everything is set to "not configured" so this should not be disabling any functionality.
Thanks.

Hi,
Firstly, if the server is domain joined, when it starts to detect the network location, the machine will contact a DC via port 389. If this detection successful, it will get the domain profile. And we cannot change it.
However, if the server is not domain joined, the domain was not found or process failed, NLA will let you to determine which firewall profile will be used, private or public.
We can do this by referring to
Turn sharing on or off or
How to change network location type in Windows 8.
Also we can refer to
Network Location Awareness (NLA) and how it relates to Windows Firewall Profiles.
All the above articles can apply to Windows Server 2012.
Hope this helps.

Change network location on a domain controller

This thing is driving me crazy. I have a virtual server with Windows Server 2012 R2. It has one NIC, which gets the internet address through the hosting company's dhcp. It is a public IP address. I've installed the Microsoft Virtual Network Adapter, which
has a Static IP of 10.0.0.1. The server was upgraded to be a domain controller.
Now the problem: it detects both networks as domain joined and puts them under the same domain profile of the firewall, although it should put NIC1 another the public profile, and NIC2 (the virtual one) under domain.
I've tried every possible thing I could think of. Going through GPO's to change network location, then blocked everything on port 389 on the firewall, so he cannot find himself put the NIC under the domain (I actually tried blocking every outgoing and incoming
connection on the firewall, it does not work), I even tried changing the registry. Nothing helps. It still puts the two cards under domain profile.
Any ideas?

Changing Network Location

I want to create an AppleScript that changes my network location based on the network name detected by Airport.
Currently I have to open:
System > Network > Location
And select the Location I'm at (ie. Work or Home). I'm trying to automate this change as follows:
If Airport detects a network named "Work", automatically change my location to "Work".
If Airport detects a network named "Home", automatically change my location to "Home".
Any ideas?

How to change the Network Location without admin right?

How to allow an normal user to change their network location without adminstrator rights? Thanks

You can't, unless you change your user rights to Admin. Now, you can reset all the passwords and admin through a reset process, but if this is a corporate owned Mac, you could get in trouble. Even fired. If it's your parent's Mac, then just get them to give you admin rights.

IPad sync hangs after changing Network Locations

I have a problem where often after I change Network Locations, the next iPad sync will hang in Step 1 of 5 with the progress right under the "e" of Step.
I have let it sit there for hours and it never progresses. I try to eject the iPad, it will never eject it.
I have sort of a formula to recover from this.
* I have to just disconnect the USB cable from the Mac.
* I shut down iTunes.
* I reboot the computer.
* I try to power off the iPad by holding down both buttons.
* It will hang for ever with the little spinning thing going in the middle of the screen.
* I will hold down the both buttons again and it will finally power off the iPad.
* I boot the iPad again.
* I bring up iTunes on the Mac and connect the USB cable and let it try to sync.
* This will fail the first time on Step 5 of 5 with the message "iTunes could not back up the iPad "My's iPad" because an error occurred. OK.
* I click OK.
* I eject the iPad.
* I shutdown iTunes and bring it back up.
* I plug the iPad back in to the MacBook Pro.
Now the iPad will sync and continue to sync normally unless I change my network "Location". Once I change my Network Location there is some probability that iTunes and the iPad will get into this stuck condition.
I've looked at the main console logs and All Messages. I don't see anything obvious.
Is anyone else seeing this behavior?
Does anyone have some hints about how to debug this?

Hi,
Tap Settings / General / Reset / Reset Network Settings.
See if that helps...
