PowerPC :: G5 Network Connection Fails "other Application Changed"?
Jan 12, 2011
I have: Power PC G5 dual 2.3 w 10.4.11 os, Lost Internet connection. (ethernet cable direct to router), No known cause. Checked router,cable etc. All work fine w other computers etc. router does not "see/read" when cable connected to G5. I figured Ethernet card is dead. Can't afford new card figured I'd try: Net gear G54 wireless USB adapter, just to get back online. Downloaded driver for Mac etc. Went to System Prefernces to set up. Opened System Preferences then Network, Automatically this message drops down: "Your network settings have been changed by another application" When I click "ok" same message automatically drops back down. Cannot access "Network settings" at all.

My neighbor has an IMac with OS 10.4.11 installed. When I open System Preferences and select the Network icon, the Network window comes up but it is overlayed with a message that states: "Your network settings have been changed by another application." When I click OK, this same overlaid window comes back.
The only way I can get out of System Preferences at this point is to do a Force Quit. In other words, because this overlaid window appears, I am unable to access the Network window to look at TCP/IP settings, make changes, etc.
Next I went into System/Library/Preference Panes/Network.prefPane(more info) to look at the application that appeared in the "Open with" field. It stated "System Preference." I replaced this with a new "System Preferences from the Applications Folder, but the same thing happened - even after I rebooted the computer.
Please let me know how to solve this problem so I can access the Network System Preferences properly.
Thank you.

I use VPN to connect to my work. Sometimes I leave it on when I stop for the night. When I go into work, I usually can login to my laptop either via VNC or ssh even when the tunnel is enabled. But, now my laptop becomes totally unresponsive and unable to receive or initiate connections.After I came home, I tried the basics. DNS completely failed. Connections to my local network seemed to work OK (192.168.1.X). However, anything else was not possible. I tried running nslookup to see what was happening. [code] I tried using ifconfig to take the network interface down and then back up. I tried disabling and re-enabling wifi. About the only thing I've been able to do is reboot the machine.

I have a Mac Mini running OS 10.6.8. Â
Suddenly the networking functionality has stopped working and the diagnostics fails to fix it. It shows all green lights apart from Internet and Server which both show as FAILED.Â
My router is operational and does assign the Mac Mini the correct IP address (confirmed by the Mac Mini and the Router). All other devices on the network work and can access the internet as usual. Â
I have tried everything that I can think of but just can't get it working again. Â
The same symptoms occur for both the wired ethernet and the wireless connection with the build-in airport.Â

My isp (Comcast) informed me that I could no longer send emails unless I changed my email port from port 25 to port 587. When I open my network preferences to make the change I get a message that my network preferences have been changed by another application. When I cancel the message it reappears and will not allow me to do anything even quit network preferences.

when I open my Network in System Preferences, "Network settings have been changed by another application" pops up and every time I click Ok, it pops up again, not letting me be able to access any other option in the Network window. The wireless icon has disappeared from my top bar and the only way I have managed to get online is via my ethernet cable. I have had nothing but problems since I started using my O2 Wireless Broadband dongle and I've noticed that behind the "Network settings have been changed by another application" notification, I can seen the Dongle has appeared as a new network connection option... but was never there before today (have been using the dongle for two months now)

I'm getting a message every time I open Network in System Preferences saying "Your network settings have been changed by another application". I click OK, and the box goes away and immediately comes back. It means I cannot use the Network part of System Preferences at all, because this message is caught in some kind of loop, and won't go away.

I'm looking for a solution to my WiFi internet connection. I haven't used my MacBook Pro laptop in the last week or so - which means there is no way I have done any changes to the network configuration. However when I now try to connect to the internet via a Hub - which is previously set up on the macbook and worked no problem - is now not working at all.

I connect with my MacBook Pro via ethernet to the internet. So far, I've never had a problem until a couple of days, I keep on loosing the internet connect. When clicking through diagnostics, ISP, Internet and Server show first organge then turn red. If clicking through the diagnostics, sometimes I am lucky and it shows a message saying "Network configurations have chnaged", when I click ok, I'm online again. But very often nothing helps and I have to re-start the router again.

I am running OS X 10.4.11 on a "pod" iMAC. When I open system preferences and click on network, I get a pop up window that states my network preferences have been changed by another application. When I click on the green "OK" box the pop up goes away and comes right back. This is driving me crazy because when it gets into this cycle it's almost impossible to get out of the preferences panel or even check the settings! It's like it gets into a closed loop and won't let you do anything.

Well I'm here at college and my iBook keeps giving me connection errors when trying to connect to the wireless network. It works fine at my house but it only works occasionally here at school. I'm not sure what the problem is but I was wondering if anyone has any ideas of what I could try to fix this issue.

I have a new macbook pro and application install disc keeps failing stating that "The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance."Â
Am I supposed to do something special to get around this?Â

The internal modem in my PowerBook Pro (mid 2010) shows up as "not connected" in the Network pane of system preferences, but I can't figure out how to get it to connect. When I enter my phone number and click the connect button, I get an error message: "Network Connection The communication device selected for your connection does not exist. Verify your settings and try reconnecting."Â Say what? It says it exists in the System Preferences, shows it in the list on the left. How can it not exist?Â

I have a MacPro Early 2009, 2 ethernet ports.Ethernet 1 is connected to the LAN and Ethernet 2 is connected directly to a SSL Matrix console (an audio mixer), whom driver needs the used ethernet port to be first of the list in the Network connections list in System Preferences.So when I browse internet I can't use the Matrix's software, and vice versa.I had to create 2 different network positions to browse internet and to work with SSL Matrix, one with Eth 1 first place, another one with Eth 2 first place, and I always have to swap positions.Is there a way to force OSX to use by default the 2nd connection of the list for internet access?Â

I have a Dual 1.8 GHz Power PC G5 and am running 10.4.11. When I select software update it says, "software Update can't connect to the update server. Make sure you are connected to the internet..." "Software Update can't check for updates because of a network problem." However, my internet connection works fine for everything else. I do have two peripheral drives connected. One of them had the same system as my main drive. However, the problem persists even when they are disconnected and I reboot. I can get the updates if I reboot from the peripheral.

As of this morning my Macbook is failing to connect to the internet even though both the ethernet and airport are showing they are connected and are green in the network panel. My husband's internet connection is fine (we both have Macbooks and go through the same router) hence I'm able to send this out. After looking at a similar discussion list, we have tried restarting the computer, deleting airport and adding it back in (although it's also an ethernet problem), deleting system configuration, restoring the whole Library..

I am on a Mac Mini connected to the Net via a FON wireless router and Ethernet directly to my broadband modem. I have had problems with both the modem and an Airport Extreme, which eventually died, but I am back up again with the modem via the FON router.The odd thing is that I can't get Ethernet to work over a direct connection to the modem. Diagnostics tells me that the ISP and Internet fails. I can connect to the modem over Ethernet, however, change its settings etc. in my browser. There are solutions mentioned here involving changing the etc/authorization file, but wouldn't that also affect the WiFi if that was the problem?Â
In short, Ethernet connection to modem works. WiFi connection to FON router and then to the ISP and Internet works. But the Ethernet configuration does't go that last bit, it only works locally. Using that route, I can't connect to the outside world. I have restarted the modem, the computer etc., but that should not be the problem as both works over WiFi, using the same settings for the modem. How do I best troubleshoot this? I am getting an AirPort Express, perhaps it will work better with the modem that the computer itself, but I doubt it.

My computer (OS X 10.9.3) and my iPad (iOS 7) are both connected to the internet via WiFi from the same modem. Fairly often the connection fails for the computer (sometimes once an hour or more) while it remains stable for the iPad. My internet provider finds no fault with the modem.Â

I can see this seems to be a common problem, and it is amazing that there seems to be no consensus (that I can find) on what the underlying problem is.I have two Macbook Pro 13's.Pretty much identical setups (Lion 1.7.3 etc.).One, works flawlessly connecting to Wi-Fi whether that is my Airport Express, or any other open or closed networks.The second, will continually refuse to connect to the Airport Express or even a wide-open 802.11b network.It will continually pop up the "connection timeout" erorr, and refuse to connect.Iphones etc all connect perfectly.Even when connecting to the iPhone hotspot - the same error.
This will happed consistently, until I give up.I can leave it for a day (use ethernet), and come back tomorrow, and voila - it will connect.I may be able to use it for a day or several, but once it decides to 'fail', there is virtually nothing I can do to bring it back it will continue to fail over and over again.All updates are applied, I've cleaned out all other networks etc from the list.Tried all civilized things that I can.Anyone have any other insight? I was thinking to yank the wi-fi module from the working notebook to the non-working one as a test.

I have Alltel Mobile Broadband. Up until the other day, it's been working fine. I'd set up a network on my macbook after connecting to the Alltel network, then I'd enable internet sharing. Then my iPod Touch, iPad, etc would all be able to go online.
The past couple days, however, the connection just won't share.Anyone have any idea what could be doing this and how to fix it?

I have a problem that when selecting a file that is either an attachment in email or is in my finder, double clicking on it fails to load the associated application successfully. For example, selecting a pdf file results in the pdf reader logo appearing on the lower bar on the screen, bounces up and down as if it is doing something, but just continues to bounce. I have to force quit it, then go to my application folder to load reader directly, and from within the reader I can then go and select the file. This isn't an application specific issue (It does it with Excel, Word etc).Â
It only started recently. I'm using a MBP summer 2010 with Mavericks 10.9.4. Everything else seems to work.Â

I am connected to the internet via a belkin N+ router..... this is in turn connected to an adsl modem...I am having no problems with the signal to the router but at least four times a day my internet disappears....
When I run Network Diagnostics hey presto, your internet is working fine....The only things I have changed recently was that as I am running osx 10.4.11 I was having that issue where you couldn't access Network in sys pref, it kept saying "your settings have been changed by another application", I found a solution on here whereby you delete the plist prefs and rebuild them... That worked a charm but now I'm wondering is this connected in some way....
or...
I got software from the makers of the belkin N+ wireless usb dongle chip that came with my router (belkin don't provide osx support but said that I could get a utility from the chip makers) I installed this but it never worked so uninstalled it, and ran disk utility and safe boot and pram and fsck (everything I could think of)
I only have one location in network, and airport is the only active network port
any ideas...????
System:
imac G5 20" | osx 10.4.11 | belkin N+ router | airport extreme card

The color of the application switching overlay changed to a black instead of the standard white. I don't know how this happened. Also the color of the on-screen overlays for changing the display luminosity, keyboard backlight and volume changed to black. How to set it back to the standard white?

I am a comitted Mac switcher trying to put my lovely new MacBook onto the office Windows network. I can connect to the office wireless network (WEP key etc) and the little radar Icon in the menu bar lights up. However, I cannot get the MacBook to obtain an IP address via DHCP. I just keep getting the default self assigned address (169.....).
However, when I connect to the network via a cable using the built in ethernet connector, I get the DHCP address just fine and everything works OK.Also, if I assign an IP address manually to the wireless card (checking it is a free address!) it accepts the settings but I cannot network, not even a basic ping of another machine on the local internal network (all our internal machines are using 10.0.0.x addresses and 255.255.255.0 sub net)The DHCP server is not in the wirless router but is a Windows server machine.This is driving me crazy. I have called Apple care and they just dont want to know because there is a Windows machine in the mix. I expected better from them,

I've searched and don't see anybody else with this problem. I tried to set up an ad hoc network on my MBP so I could use TouchAble with my new iPad. But now I can't get my MBP (or iPad) to see my home wifi network.
(TouchAble is a music performance app on the iPad that controls Ableton Live on the MBP. It works on an ad hoc network so the combo will work on gigs without depending on local wifi.)
I set up a new network ok, with a password. The iPad saw it, but before I tested it further I wanted to make sure I could reinstate my regular network. So I tried switching back to the regular wifi. No dice! The MBP sees the network, but I can't log in. It acts like the password is wrong. Same on the iPad.
Yes, the network works. I didn't make changes to the settings in my router, and my iPhone still sees it with the same password.
I tried a tip I found online and deleted the network preferences file (com.apple.smb.server.plist) and rebooting. No dice. (The system didn't write a new one, as I had expected; I had to reinstate it from the Trash). I rebooted a few times, both MBP and iPad. Nope.
What's going on here? 1) How can I get my MBP to see my network, so I can switch back and forth from the ad hoc to the local network. 2) Ditto for the iPad.
MBP is new. All systems and versions are up to date. No other funny stuff with the network--it's been stable for two years. Everything is stand-alone; this is in my home office. I'm the admin. (But I'm not a techie, so if you start talking about IP addresses and subnet masks, please be clear what I should try.)

iMac OS 10.4 - was working with dial up modem but wanted to plug into my network for high speed internet access - after plugging in RJ45 cable, the network was not accessed but the computer continued to go the dial up route. When attempting to change network preferences a flap keeps appearing saying the preferences have been changed by another application - this flap appears over and over and will not allow preferences to be changed. Dial up still works by clicking on the phone icon at the top of the screen. Any way to reset this without reinstalling the system?

I finally got around to changing the way my wirless devices are set-up; instead of using time capsule as my wireless device, I went back to using the linksys wi-fi router (which I'd used prior to time capsule, but now set up as WPA2 if it makes a diff?) with the intent of putting time capsule in another room with my 1TB iTunes library hanging off it. All seemed to work well but I initially had a problem with the TV keep dropping the wi-fi connection. Now connected via ethernet to the linksys, no problem. iTunes streamed okay but I couldn't seem to get time machine to make a back-up - just prepared forever (overnight, still no joy).
So I noticed today that I seemed to have lost permissions on both iTime drive and time capsule. I managed to fix the iTunes drive by connecting direct to my macbook and running disk utility then adding myself again via sharing (hip hip for MRoogle), but I cannot do the same with the time capsule. Even with airport utility and connected via ethernet I can't even get the configuration up - just spins out until it throws an error. Anyone have any ideas as to what I'm doing wrong - I'm assuming it's me as this all worked in the previous set-up...

I own a PowerMac G4, 1.25GHz. It came with no OS (donated by my local college to my high school and eventually given to me for my services in fixing this and the other 6 PowerMacs, and the 7 iMac G5s), so my IT teacher and I copied OS X 10.4.11 from one like it. That is currently my primary OS. We read online while thinking about upgrading his and mine Apple PCs to 10.5 Leopard, about the system requirements. They all line up [URL]:
- A Mac computer with an Intel, PowerPC G5, or Power PC G4 (867 MHz or faster) processor
- 512 MB memory or more
- A DVD drive for installation
- 9 GB of available disk space or more
With a 1.25GHz PPC, 2Gb of RAM, and an 80Gb Seagate IDE HDD, I'm all set up, right? On Friday, before the end of the day, I copied OS X 10.5.7 Leopard from an iMac G5 w/ G5 iSight (late 2006 model). We plugged it into his iMac G5, runs like a charm. Plug it into the "test" G4 (exactly like mine, but only one Seagate 80Gb IDE HDD), and it took a while, but it booted. So today, I copied it to my blank Seagate 80Gb, assuming that it would boot like the LaCie External HDD did (yes, that worked too).
It finishes copying, I reboot, hold option, punch in the lock code, and Low AND Behold... No Seagate. Mac OS X 10.4.11. But no Mac OS X 10.5.7. Okay. So I boot back to Tiger and recopy. Try to open a couple programs, they work (Office 2008 Word, Dreamweaver CS3, and iTunes 9.2). No problem. Open System Preferences, choose Leopard as the initial boot device, reboot. Mac starts up, and I get the screen with the little folder that alternates between the question mark and the Finder icon.

So I was just there, using my computer, doing nothing out-of-the-ordinary. I decided to open up a program (Yahoo! Instant Messenger, I think it was) and the computer went nuts. I completely froze...nothing I tried worked. So I shut the computer down and tried rebooting it. It chimed and went to the white start-up screen with the apple...I let it sit for about ten minutes to let it restart. Still the white screen. I shut it down and tried it again. Same thing.
Is my computer dead? What might I be able to do to fix it? How much might it cost?
