Dial-Up Service, iMac is connecting after StartUp

Hello,
All of a sudden, my iMac 9.2.2 has started to dial a connection (by it's self)right after Start-Up. Normally, after Start-Up, I click on a Browser (IE,Netscape,iCab)or Outlook Express and the iMac starts dial for a connection.
I have tried dumping the following Prefferances:
Start-Up Prefferances
Remote Access Preferrances
And then Restarting, but this problem continues.
Any ideas or suggestions appreciated

Hi, Steve -
There are several possibilites of things that can auto dial a connection to the net.
In Apple software -
• the Software Update control panel has an automatic check for updates setting
• the Date & Time control panel - Use a Network Time Server function
• the QuickTime Settings control panel - Update Check page, at the bottom
In addition, some non-Apple software have automatic check for updates functions. This can include Symantec's Live Update; some graphics apps, MacTracker; etc.
Also, check in the Startup Items folder (in System Folder) for an item, such as an alias to a registration utility, which may be the cause.
And, a remote possibility - check in the Servers folder in System Folder for an alias to a web-based server.

Wifi no longer connecting after startup

wifi no longer connecting after startup... so I have to connect manually... started after 10.7.3
any ideas

Which computer are you experiencing this on?
There are several threads dealing with (mostly) iMacs + bluetooth keyboards/mice and issues with WiFi no longer automatically connecting. There seems to be some issue that 10.7.3 introduces with these series of macs.
No Apple provided solutions yet, but several workarounds: 1) attach a network cable direclty from modem/router to mac; 2) use the power button instead of mouse/keyboard to wake up mouse; 3) use USB keyboard/mouse (not personally confirmed); use airport extreme/express as a bridge.
Right now it's a waiting game until Apple provides another update. I do recommend going to Apple feeback: (http://www.apple.com/feedback/) and at least voicing your opinion. Calling AppleSupport will do the same, but they'll make you go through the same (likely useless) steps everyone else has done.
Good luck!

Possible hack for iMac not connecting at startup with WPA2

Hi,
Like many others whose iMacs fail to connect at restart or after waking from sleep, I've tried all the suggestions with no improvement.
Then I tried the following (this is AirPort specific, but other routers may have the same setting):
1. Open Airport Utility
2. Click the AirPort Icon
3. Click the Wireless tab
4. Click Wireless Network Options...
5. For WPA Group Key Timeout, change the popup from hours to days and enter e.g. 30 days
6. Click Done
7. Click Update and the AirPort will reboot.
After it comes back online, try rebooting your mac. YMMV, but if you're like me, the connect at startup issue will be fixed (at least for 30 days

Hi, this has worked for a few...
Make a New Location, Using network locations in Mac OS X ...

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
For 10.5/10.6, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

Click OK.
Also, turn off IPv6:

Or whatever Interface you use.

Please Help: iMac black screens after startup logo + spinning wheel no cursor).

Hi, guys.
I'm in a fair bit of a desperate situation; my iMac's screen seems to shut down every time after the white startup screen. The Apple logo appears, & the progress wheel begins spinning, then after a while - when it would usually then go to the gray login screen - it would, instead, go black. I can tell that the machine is still on (I can still hear it clicking as it does during processing) but I'm unable to determine anything else. Nothing is visible on the screen - not even the cursor - it's as if the display had turned off completely. I'm not sure if the login screen sits beneath that black screen (I have tried to log on by typing my login details in blindly, but even if it does log in, it's hard to determine what state the computer is in without seeing the screen.
I have tried the PRAM reset (holding CMD+OPT+P+R) during both the white startup screen, & the black screen to no avail. It seems unresponsive because I don't hear any additional chimes that I've been told should be heard during a PRAM reset attempt. I can't even be sure that the command is being inputted correctly because the light on my wireless keyboard remains off during the process.
I've tried rebooting over & over again; the results are the same.
The steps that led to the problem occurred thusly:
1 - I was trying to clear some memory from my current session, so I scanned through my active processes, quitting anything which seemed to be eating up considerable amounts of memory.
2 - One particular process I quit was 'launchd' which was functioning under my profile username.
3 - After quitting launchd, all opened apps seemed to close, & it looked like I was forcibly logged off the machine. The screen froze during this point, & I decided to do a hard reboot to log back in.
4 - The problem began after this hard reboot; startup seemed to occur as per usual; white screen > apple logo > progress wheel > and then suddenly, a black screen where the login screen should be.
I've shown a flashlight into the screen while it's black & it seems well & truly like the display has shut down while the iMac continues in the background. I have had issues relating to my screen going black before, but they were random & intermittent; they didn't occur without fail during the exact same time immediately after startup, & could be remedied by using the CTRL+OPT+EJT keys.
I am on an iMac 2010, 27", using I believe Lion OSX. I am unable to recall additional specifications while the problem persists.
Could anybody please help me? I'm quite desperate; I was in the middle of some urgent work that I need to get back to as soon as possible.
Thank you I'm advance to anyone with advice on how I can go about fixing this.

Gray screen appears during startup

Mac connects then drops wireless connection after startup

Hi, I have a strange problem. I recently purchased a new MBP. My old MBP didn't have any problems with the router, but my new one, after coming out of sleep, will be connected to the internet for a couple of seconds, then drop it like it's searching for a signal, then be connected for around 20 seconds but no actual internet connection. I know that it initially is connected because I can refresh the page or connect to a webpage for about 5 seconds, but then it starts "looking" for the signal. And of course, once it finds the signal, it doesn't actually work for another 20 seconds. I wanted to blame the router but no other computers have this problem. Can anyone help me?

If you are using W7 -- scrooge is correct - it is not listed on Linksys' W7 Comp. list - http://tinyurl.com/yd2nv5v - but it is listed on Microsoft's Comp. list - http://tinyurl.com/y9vuwdm - confusing!!
FYI - I'm using a #320 router with the WUSB600N adaptor ( Win 7 driver - Ver.3.1.0.1.0 ) on a 64 bit platform desktop with no issues at all - I believe W7 found and loaded correct the driver for the 600 adp. --- or you can check for the correct driver for the adp. in the Device Manager if you decide to try the USB adp.'r

Installed ok but now my iMac freezes right after startup

Leopard installed (updated from 10.4) ok, I had to restart once during it but it went ok. Once it was installed it froze once, so I rebooted and it seemed to be fine. I ran the software updates and since then when I start it up it gives me the black tinted screen that says I need to restart so hold down my power button.
I looked in the support section and tried to do the first solution listed under 'blue screen' (I assume that's the same as tinted black overlay screen) which was to boot it as a HD onto my laptop and erase a certain file but I didn't have that file. From this posting:
http://docs.info.apple.com/article.html?artnum=306857
To make matters worse it seems as though my external HD has broken. I'm scared to try option B in the thread above without backing up my files. Has this happen to anyone else out there? I'm a graphic designer and I'm going crazy without my main workstation. I feel like a race car driver without a car.
Any help, any, would be greatly appreciated.

Hi
The screen that tells you to restart in multiple languages, is that what you're referring to? That suggests a kernel panic, see if anything at http://www.thexlab.com/faqs/kernelpanics.html is helpful.

Trouble connecting iMac to internet after Time Machine Reboot

Bear with me here guys.... I recently went to download Aperture onto my Mac but found that I required Mountain Lion, so I purchased it to upgrade from Snow Leopard. Having download the new OS I started the installation and it failed as it appears I have a fault with the Hard Drive; though my Mac gad operated just fine previously. As everytime I restarted my computer it wanted to start installing Mountain Lion but couldn't complete due to HD error; I rebooted via the Snow Leopard CD and loaded my last Time Machine save. I now have the Mountain Lion icon sat on my dock awaiting installation, though after I've had the HD fixed first obviously.
So having just reloaded the OS and rebooted via my Time Machine Backups (For which I use a USB connected Samsung External Drive) my iMac will connect to my wireless network via Airport just fine. Loading the internet via Safari is another matter. It will load the window but will remain blank white with the pinwheel spinning. Eventually I get the message that another computer using the same IP address is already on the network.
Having read the threads on here I have already tried resetting Safari, restarting my Router, I have double checked all the IP adresses of my another connected devices (none hold the same IP address as the iMac) have been round in circles in Network Settings Renewing the DCHP Lease, trying the set the IP address manually, turned everything off and on again and I have spoken with my service provider and they have not been able to tell me any more than the threads on here; and so here I am at a loss now.
Any or advice would be really appreciated.

Just a few more ideas...
Searching the web, I've found some possible fixes, some of which you have probably already tried.
Try connecting directly to the router with an Ethernet cable.
Check your wireless security (you should use WPA2, it's the strongest). Someone could be using your network, so try changing the password and see if that helps (this can be a pain if you have a lot of devices).
Flush the DNS cache:
For Lion and Mountain Lion: Enter the following command into Terminal:
sudo killall -HUP mDNSResponder
For Mavericks:
dscacheutil -flushcache;sudo killall -HUP mDNSResponder
Update the router firmware if it is out of date. Also, you can reflash with the current firmware, which [i]might[/i] help.
Hope some of these help, if not best of luck with getting the fault sorted out.

No automatic connection to a wireless router after startup!

After adding a new wireless router to my home network an iMac G5 does not automatically connect to the wireless network after startup.
And so the story began: I'm running a wireless network for years without problems at my home. The wireless router is a Orinoco 102.11b with 128-Bit WEP encryption and I have 4 different Mac connected to it.
Because I wanted to use the higher 54 MBit/s speed and a more secure encryption for my network I've installed a LINKSYS wireless router and configured it for 102.11g and WPA2.
Everything worked fine except the automatic connection after restart on my iMac G5 running Mac OS 10.4.10. I can connect to the new wireless router but I have to do it manually after each restart. The password is therefore stored in the login keychain. The connection can be established automatically after sleep but not after startup...
So I switchted the connection back to the old router and got unfortunately the same behaviour. The iMac does not connect any more automatically to the router after startup. I removed the new router from the network, deleted all wireless passwords from the system and login keychains, created new keychains, switched back and forth the preferred vs. automatic network selection, created new locations, changed the root password and so on...
It seems that the new password entry in the system keychain causes an error in the password encryption of the system keychain which prevents the automatic connection to the network after startup. Replacing the keychains from my backup does not work either after I've once created a the system keychain.
Is there any log file, which may proof my assumption or can give me some more information of the erroneous login process to the wireless network during startup.

One thing that can work, try this, *please ignore the exact symptoms and connection and Hardware types*, it's worked for many others than the stated...

IMac freeze after startup, works fine in safe mode

Hello, my Mid 2010 iMac is freezing about 3 minutes after startup. Ive tried booting from the instal disk and repairing it but it didnt work. In safe mode it works completely fine. It similar to some other peoples problem but i was hoping someone could help me, my applecare literally just ran out like 3 weeks ago.

Hi baltwo,
Im sorry but Im new to the community and I don't know how to address users directly. Hence intruding.
It would be kind of you to shed some light on the matter.
I'm running lion 10.7.5 and followed similar procedures but mail downloads every mail again after cataloging and indexing my earlier(snow leopard 10.6.5) mail. More details at https://discussions.apple.com/thread/5373643
It would be great to find a solution as I'm struggling since two weeks.
Thanks,

I'm trying to connect to my home wifi with my imac gh5. After I enter the password it says connection timeout or password incorrect. I know there's no issue with the connection but I don't know what else to do. Does anyone know how to fix this problem?

What is the make & model of your home Wi-Fi router that you are attempting to connect your G5 iMac to? Which exact model of iMac do you have?
What wireless security type is your router using: WEP, WPA, or WPA2? If you temporarily disable wireless security, can the iMac connect to it now?

My iMac freezes up shortly after startup.

My iMac freezes up shortly after startup. I can't move the mouse or use the keyboard. I have to manually shut down several times before it would work.

Hi patrickbryant,
Thank you for participating in the Apple Support Communities.
If your iMac is becoming unresponsive when you start up, I recommend trying to boot into Safe Mode as well as using Disk Utility to verify your hard disk. You can find these steps outlined at this link:

After 10.6.2 update Entourage Web Services Edition cannot connect

After I updated 10.6.2 patch, Entourage 2008 Web Services Edition cannot connect to the Exchange server anymore.
I removed the office 2008 and re-installed with all the available patches. Standard version of Entourage is able to connect and synchronize however Web Services Edition is not able to connect. Web Services Edition is using Exchange Web Services as primary connection protocol to the Exchange Server.
Nothing has changed on the server side and Apple Mail can connect to the exchange server. It seems to be related with 10.6.2 update. Any idea what might cause the problem and how to fix it?

I managed to get the connection log from a working system and compared it to mine. During the Autodiscovery part the only difference I found was related with timezone. Below is the exact text from the log files:
*Successful connection:* <t:TimeZoneContext><t:TimeZoneDefinition Id="Georgian Standard Time"/></t:TimeZoneContext></
*failed connection:* <t:TimeZoneContext><t:TimeZoneDefinition Id="(null)"/></t:TimeZoneContext></
After figuring out this detail I checked the computer timezone again.
Both computer and Entourage was set to GMT+4 but the cities were different. Computer was set to “GMT+4 Dubai” and Entourage was “GMT+4 Abu Dhabi, Muscat”
Even though time zones were the same, Dubai is not defined as a timezone city in Entourage. I changed the computer timezone to “GMT+4 Muscat” and the connection established.
This is the most stupid error I ever seen...

IMac 24" OS X 10.5.8 crashes after startup

After startup, my iMac crashes after a short while (from 10 seconds up to 10 minutes). The screen freezes and the keyboard doesn't respond. I can't click, however, i can move the cursor around. This iMac was bought 2008 and I've never had any problems like this before, and I have no idea what made it behave this way. (I noticed it had crashed when I tried to wake it up from sleep mode a couple of days ago.)
Things I tried that didn't fix the problem:
1. Shutting down and disconnecting power cord for 30 seconds
2. Reseting PRAM
3. Created a new login-account
4. Repaired disc permissions in Disc Utilities
5. Hardware test (holding "d" during startup)
(OBS. I've tried the extended hardware test several times but sooner or later it crashes, always before the test is finished!)
In Safe Mode (holding "shift" during startup) though, it doesn't crash, but then I can't have sound etc.
What kind of problem could this be? What should I do?

You mentioned running Apple Hardware Test however I'm guessing you may not have run in Extended Mode. If you did not then you really haven't tested it. When you start AHT look for Extended Mode and follow the instructions. This test will take significantly longer to do. My guess is you have temp sensor or HD problem.
Another thing you can do is run Activity Monitor when operating normally and look to see if you have any processes that are using a lot of %CPU, if you do that's a sign you have a problem process. You can also look for how much FREE RAM you have (it's under the System Memory tab) however being low on RAM would not cause a crash it would cause a slowdown.
