IMac OS X 10.7.3 unable to lock network and share settings

I use only Wi fi network, when i have finished setup it up it will not lock, also the same with sharing.
iMac OS X Lion 10.7.3

Run Software Update to get your system updated to the most up-to-date version of OS X. There was a fix for Wi-Fi that went out some months ago for 10.7.3, the update will include that. Also reset or replace your router, most problems with Wi-Fi are caused by the router, yes even if you have other devices that seem to get Wi-Fi.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

My iMac does not see the windows machines on the network (and vice versa)

I'm runningOS X 10.8.2 on my iMac which attachs to the office network using Wi-Fi.
It's on the right network (it's not attaching to the Wi-Fi router in the bulding next door) - I've checked the SSID and it's also being issued the right IP address by the router.
I can ping the Windows machines and they can ping my iMac. The issue is that I simply CANNOT share files back and forth.
At seemingly randoms times, I can, and I have File Sharing enabled in Sharing (remember, and RANDOM times I CAN see the Windows machines and they can see the iMac...BUT, it's random).
Thoughts?

zahidfh, Welcome to the discussion area!
More than likely your area has very significant RF interference in channels 1-6. The interference is making those channels unusable by you.
KB 58543, AirPort: Potential sources of interference
Also, is this a forum where Apple technicians reply to queries??
Take a moment to read the "Help & Terms of Use" for this area and you will discover that this area is a user-to-user discussion area. There is no guarantee that anyone from Apple will ever read any of these threads.
I was unable to find any area where I could post a direct help request regarding this!
That is because one does not exist. If you want to communicate with Apple about a problem or issue you must call them.

IMac won't connect to the to the wireless network and internet when a laptop is connected

When a windows laptop is connected wirelessly to my router and the internet my Imac won't connect. If the Imac is connected wirelessly first it turns off when I connect the laptop. the iMac has once given me a message about the laptop using the same IP address. Can anyine help, I have been putting up with this for a year now and it's a real pain. Any help appreciated Many thanks

Check the company that you get your internet service from. High speed internet through a phone service modem allows for one connection as the modem is controlling the IP addresses. If you add a wireless to this connection, your modem will still allow for only one connection at a time. The wireless modem should be "in charge". Call the internet service provider and see if they will walk you through how to give permission to your wireless to assign IP addresses and not the modem they supplied.
If your Mac and PC both want the same address, you can tell your Mac to use a manual IP address. Go to:
system preferences/network
write down the IP address, subnet mask, and router numbers. On dropdown Configure IPv4 choose "using DHCP with manual address". Now put back in all the numbers you wrote down except in the IP address box, change the last digit to a higher or lower number.
Now the PC will be happy with the IP it chose and the Mac will, also.

Imac 2009, 10.7.4, track pad cursor locks up and won't function

My cursor has locked up the past few days.
It won't function at all except to move around. I've had to do a hard shutdown and restart to get things working again. Any suggestions?

Select  ▹ System Preferences ▹ Bluetooth. Select the device in the list on the left, then from the action menu (gear icon) below the list, select Update Services. If there's no improvement, delete the pairing from the list and recreate it.

Trying to connect to a known internet connection but i keep getting the response "unable to join network"

Trying to connect to a known internet connection but I keep getting the response "Unable to join network" and the internet is connected, please help.

Okay now this description was pretty vague but it could be a few things. First thing to try. Turn wifi off and then one again and try to connect. If this fails read on.
The second step is to select that network in the wifi settings so you get an expanded menu of it. Follow these steps from the home menu on your ipad... SETTINGS>Wi-FI>NETWORK NAME (you have to click the little blue arrow)> FORGET THIS NETWORK. Then turn wifi off and then on. Then try to connect again. If this fails... well read on,
Okay, so now you really know it's most likely not your ipad, so go on down to your wifi router and turn it off, wait ten seconds, turn it on again. WITH YOUR IPAD OFF. Then turn on your ipad on and then try to connect again. If this fails... Then you'll have to do some more complex things. You could try setting up the network again. IF that fails too. Leave some details about your router, brand, year etc... And I'll try to let you know what else it could be.

Every time I fire up my iMac a window pops up saying "Mount notification quit unexpectedly" and it gives me the option to either "Reopen" it or click OK, which gets rid of it. What is this please and how can i stop it?

Hopefully this will help you. Try placing your iPad in recovery mode again. You may have to try this a few times.

Hello, I have a macbook pro late 2011 15 inch with 4 gb ram. My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Is there a fix?

My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Furthermore, when just using safari to watch streaming television, my computer gets really slow, and locks up, and the dock appears blank and I sit here frustrated. Anytime i wake up my computer, my keys don't respond and I've waited at most 3 minutes untill i can type in my password. Even sometimes when i type in my password and hit enter, it takes forever to open up my mac. I have barely used any storage in my macbook, since i only use it for college, and I have run clamscan wiht no viruses showing... Any ideas?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Every time my IMAC is unused for a period, then goes to sleep mode, it loses it's wireless connection and when I wake it up, it DOES NOT automatically reconnect. I have to go to systme preferences network and request that it reconnect.

My iMac is set up wireless. Everytime it's allowed to go in sleep mode, it loses wireless connectivity. Then, when I wake it up, I must go to System preferences, Network, and request it to reconnect to my home wireless network. It always does this successfully, but it's quite annoying that it seems unable to achieve this on it's own. My iPad 2 and kindle can do this, why not my iMac?

This appears to be a known issue, there are a couple of things both of you should do, first file a bug report in www.apple.com/feedback.
The next thing is more a work around than a fix. Instead of putting your computer to sleep just put the display to sleep. You will find this in System Preferences - Energy Saver. Set the computer sleep to Never and then set the display sleep to what ever time you prefer.

IMac won't turn on. Only a clicking sound and a grey folder with flashing question mark.

iMac won't turn on. Only a clicking sound and a grey folder with flashing question mark.
Help.

Your iMac is actually turning ON as proven by the grey folder with the flashing question mark.
The flashing question mark indicates that your system is unable to find a bootable volume. The clicking sound that you hear is probably coming from your hard drive while it tries to recalibrate. I suspect your hard drive has failed.
What model imac do you have? If it's under warranty I suggest taking it in for service. Hopefully you've been maintaining a regular backup of your data as all users should. I lost my data once and it was a valuable lesson. I back up regularily now.
If your iMac came with install disks then you can boot from them, choose your language when asked, then pull down the Utilities menu to launch the Disk Utility application. The Disk Utility application will allow you to verify whether your hard drive has an issue. Usually a clicking sound, assuming it's coming from the hard drive, is a sign of a bad hard drive.
If your system has Lion installed then you can hold down the Command and R keys when you restart the system, then launch the Disk Utility application from the menu that appears.

Unable to move music and pictures to iphone 4 iTunes shows sync complete = nothing on iPhone

iPhone sync issues: unable to move music and selected pictures from iMac to iPhone via iTunes sync. Sync shows complete - = nothing on iPhone.

Well, you marked this topic as solved which I guess it isn't really.
You need to transfer the library with which you originally synced the phone to the new computer. A phone will only sync to the original library or it will offer to erase the phone for syncing with a new library.
Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the option (alt) key (shift on Windows) so you get a prompt to choose a library, then select the copied iTunes folder.

Unable to read burned dvd, unable to format dvd, and unable to burn dvd

Unable to read burned dvd, unable to format dvd, and unable to burn dvd with my HP G62-339WM Notebook PCI have been unable to perform the Windows back up for months without using new discs. But even after using new discs Windows backup tells me that the disc that I previously used that it is asking to insert is not formatted. I also have not been able to read any dvds that I previously burned, instead it will sometimes recognize them as blank and they are not. I also cannot perform a format on new dvd discs nor burn to them. I have been able to read some previously burned discs on another pc but not the discs that were created with Windows backup. I have tried everything. I have uninstalled the device, ran the fix it, tried troubleshooting, checked the registry and could not find the upper and lower filters listed. I am however able to read program software and the autorun pops up. Once in a while the autorun will pop up when a blank disc is inserted but then that is all the further I am able to use it. I don't know what else to do. I really want to be able to at least burn files to back up so that they are not lost forever. Please help!

Fixed it myself - for some reason the La Cie refused to read the media. Had to use another machine to pull the data from the drive, copy it over the network to my iMac and then mount the ISO image.

Unable to join network after 3.0.1

I "upgraded" my iPhone from 3.0 to 3.0.1 last thursday and since then have been unable to join any of my wireless networks. I've been able to join all of these networks via my laptop so I know it isn't the APs. I reset the network settings on the phone via Settings->General->Reset->Reset Network Settings. Still nothing.
Anyone else having this trouble? Any easy solution? Should I attempt to go back to 3.0?

It has nothing to do with 3.0.1, which was a minor change to the SMS app. You probably have corrupted data in the backup that was restored when you did the update. Thus, going back to 3.0 won't fix it. You need to fix it in 3.0.1. Try first forgetting your network in WiFi settings for it. Then reboot and try to connect again. If that doesn't fix the problem then do a Restore in iTunes and choose to set up as a new phone. Test before adding back any apps or email accounts.

Unable to join network after dropping my ipod in the water... anyone know a solution?

I put my ipod in the pocket in the back of my jeans and when i went to the washroom, it fell into the toilet... I immediatey took it and dried it with a hairdryer and then a few hours after.. it was able to reopen again, but im unable to join my network ever since then...
Anyone can help me? Thanks.

Does it see any networks? If wifi is dim or grayed out see:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
However, it is frequently a hardware problem.
If can se networks, try:
- Resetting the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Powering off and then back on the router
- Resetting network settings: Settings>General>Reset>Reet Network Settingds

ORA-27086: unable to lock file over NFS -- but it's NOT Netapp!

My 10.2 database crashed, and when it came back I got the following error:
ORA-00202: control file: '/local/opt/oracle/product/10.2.0/dbs/lkFOOBAR'
ORA-27086: unable to lock file - already in use
Linux-x86_64 Error: 11: Resource temporarily unavailable
This is a classic symptom of a Netapp problem, which likes to hold file locks open on NFS mounts. There is a standard procedure for clearing those locks; see, for instance, document 429912.1 on Metalink.
Unfortunately, my files are mounted on an Isilon, one of Netapp's twisted cousins. I can find no references to "isilon" on Metalink, and we are at a loss how to resolve this.
My sysadmin assures me that "there are no locks on the Isilon". But I know this cannot be the case, because if I do the following:
1. delete the lockfile /local/opt/oracle/product/10.2.0/dbs/lkFOOBAR, and then
2. move my controlfiles aside, and then copy them back into place,
then the database will mount. However, it will not open, because now all the datafiles have locks.
Is there anyone with experience in clearing NFS locks? I know this is more of a SA task than DBA, but I am sure my SA has overlooked something.
Thanks

New information:
As stated above, I moved the controlfiles aside and then copied them back into place, like this:
mv control01.ctl control01-bak.ctl
cp control01-bak.ctl control01.ctlDid that for each controlfile, and then the database mounted.
But, after rebooting the machine, we discovered that all locks were back in place-- it looks like the system is locking the files on boot-up, and not letting them go. The lock is held by PID 1, which is init.
sculkget: lock held by PID: 1This is definitely looking like a major system issue, and not a DBA issue, and hence I have little right to expect assistance in this forum. But nonetheless I lay my situation out here before you all in case someone else recognizes my problem before the server bursts into flames!
The system is CentOS 4.5-- not my choice, but that's the way it is.
