Airport Problems after update and trouble shooting

Hi There,
I have an Intel iMac and after updating airport i've been having problems with it. I'll be using the internet and all of a sudden it will just disconnect and cannot detect any network connections. Now, i've seen the other posting already about fixing this problem, and I have done what it says to fix the problem by moving the system configuration folder and the com.apple.systempreferences.plist file. After I do this, it works for a few hours but then i have the same problem again. The folder and the file is recreating and i have to follow the same steps and move them again, but then every few hours it keeps getting recreating. Is there something that i can do so i'm not constantly moving the files around and having to re-setup my network. Is there a way to reset Airport to the way it was before i installed the update?
Thanks

"Is there a way to reset Airport to the way it was before i installed the update?"
Of course you can erase your hard drive and reinstall up to 10.4.7, and not go any higher. The problem is the 10.4.8 update, or some part of it. The many other updates recently posted for different apps are not part of the cause, so those updates can be installed.
"Is there something that i can do so i'm not constantly moving the files around and having to re-setup my network."
Yes, once you've followed the "restart twice" instructions involving preference file deletion, it appears that by turning off AirPort before letting it sleep, restart, or shut down, those two files will not get the same corruption recreated. Afterwards, you should be able to turn on AirPort and after a slight delay of about six to eight seconds AirPort will be able to reacquire your network.
If you forget to turn off AirPort before sleep, restart, or shutdown, then those files will again be corrupted and you'll have to go through the process all over again. I ran through it about 50 times, changing this and that, and that's all I could come up with.
Hopefully someone else out there with a different perspective will be able to figure out what else needs to be done.

Airport problems after update

I have been using my 20" Intel iMac for a few months now and have had no problems getting the built-in airport device to connect to my wireless home network. Yesterday, I downloaded and installed the new airport system update, and ever since I've been having big trouble. It doesn't show any available network connection at all (and I know my wireles network is working because my laptop can still connect). If I restart the computer, sometimes it will find my network and sign on, but then it drops the connection after just a few minutes and goes back to saying it can't detect any available networks. Has anyone else had any problems since the new update? Any suggestions on what to do? Thanks.

Unfortunately, I can't get any of your suggestions to work. If I restart the computer and go through the Network Diagnostics set-up, I can sometimes get it to find my home network and connect, though not everytime. The connection might last from 2 minutes to an hour or more, but then it is inevitably lost, and Airport shows no available networks, even though my MacBook is still connected to my home network and shows several other available networks from neighbors' houses, too. It seems like it must be a software problem since I had no problems before the update. Does anyone know anything else I can try short of taking it in to an Apple Store? Thanks for all your suggestions.

RAM Problems after update and Restart. 3 beeps with led. Memories and Slots work alone, but together the problem continues.

I make some updates and restart my Macbook Pro, and the screen became Grey with 3 beeps with Led.
I read it could be the RAM memory. So I opened it and tried to reconected them.. but the problem continues.. So I asume it was one of the memories or one of the Slots... But when I tried them separetly all the Slots and memories worked... But togheter the problems continues.
Any suggestion?
The Mac worked perfect! There where just some updates...and before the restart, a pop up appeared saying that the updates could not be done because of an error... after that... the restart, the grey screen, and the 3 beeps with 3 leds.
Thanks and sorry for the bad english!
PS: Its 2008 so no warranty.
Hernan.

Have you tried putting back the original memory and seeing if that works?
Also if you could tell us the mode of the MBP, how much memory was in it and what you are upgrading to it would help.

Airport problems after update Airport Extreeme 2008-004 V.1

Since when i have installed the update Airport Extreeme 2008-004 V.1 my Airport card is giving me problems. The network seams to go down and if i reset the Airport it restart working for a certain time. I have noted that the problem apears most of the times when Time Machine starts the backup on the Capsule (but this is not 100% sure).
I am quite sure the problem is the update because i never had this before.
This is the log..

Apple cinema Display problem after update

I had a similar problem to lain Maclreud
Immediately after updating to 10.4.11 and rebooting the toparea on my cinema display went dim and I saw the 2 short, one lon blinks on my power display LED
I didn't try it on another computer yet or try to change my power source but I may need a new backlight card as well. Please post if you have had similar problems after updating and suggest possible solutions.

Have you tried the Command-Option-P-R keys to reset the PRAM? (Maybe the upgrade has messed up the display settings?)

Force close the App Store app and reset the iPad. No data will be lost when you reset the device.
In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Next, reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Problem after update 10.5.5 and coolbook

Hi, i have a very big problem after update tp 10.5.5 in my macbook air.
i do the update with coolbook active.... and when restart... the system dont pass over 800mhz at 50ºC and all the system go very slow.
i tried to active again coolbook, restart, but coolbook dont work....
so now i have that problem.... my 1,8 macbook air dont pass over 800 mhz...
what can i do??

I'm not familiar with Coolbook, so can't really offer any help there but, have you tried disabling on removing Coolbook to see how your Air runs?
If the Air runs ok without Coolbook installed, there's your problem, if it still runs at a max of 800Mhz, contact Apple.

Airport issue after update - Status grey / Connection OK - Solved

Hello All,
Just wanted to share an issue I had that was driving me nuts, and then the final solution.
Ever since the recent airport extreme update, my airport status has been broken. The menubar icon has shown up as grey / no signal, and when I click on it, the only option I have is to 'turn airport on' which when selected does nothing.
In spite of this, though, my airport connection for my preferred network is working fine - I just can't select a new network off the list (there is no list, even in internet connect)
This has been a problem since the airport extreme update. Nothing I did seemed to help. Finally, I called apple and spent 45 minutes on the phone with them, doing the obligatory pram resets and power management resets, etc. Nothing seemed to help. We found a way to enter networks manually (go to system prefs / network / airport and add your network there) but the status problem was still there.
After I got off the phone, I went to the apple support page and found the airport extreme software update and downloaded it manually and installed it.
Manually Downloading and Installing the airport extreme update again solved the problem.
I don't know why the software-update version didn't quite work, but installing the update from the website did solve the gray / broken airport status menubar problem.
Just thought I'd share that with everyone, as it's been driving me nuts for the better part of a week.
Cheers!

I would like to confirm that update worked for me too. Actually, I didn't need to do it manually like some of you did. It worked straight away after automatic software update.
My problem was occasional inability to connect to my wireless router. The problem would have been solved by SSID change manually on the router and reconnection.
After the latest update, everything is working flawlessly.
I have (not so known) OZENDA router and didn't have Parallels installed.

Anyone has any problem after updating to iSO 4.3.1 ?

anyone has any problem after updating to iSO 4.3.1 ?
I would like to know before updating mine.

My 3G kept freezing after iSO 4.2.. and after reading the forums I updated both my Itunes and software to iOS 4.3.1, now I've lost my notes, contacts, calender entries and so far in the last ten minutes it's turned off and restarted itself and sync'd continually about 5 times.
So basically I'm still where I was before only more cranky. In addition, I live in Australia and there are no Genius places here, there is no support from Apple unless you pay for it even by an email, you basically end up fending for yourself under a supposed warranty that isn't worth the paper its printed on.
It you haven't already guessed, I'm more than a little ****** off.
If I'd known how much trouble this was going to be, I don't think I would have spent the $400 odd dollars to buy it.
If its not right by the weekend I'm taking it back to the shop I bought it.

White screen problem after updating to 1.1 firmware

My 2G iPod Nano worked fine with 1.0.1 and 1.0.2 firmware but after updating to 1.1 I get white screen everytime I turn it on after longer period of time. Turning the iPod off and then right back on makes it work again. I have done restore 3 times without effect. I even removed the firmware files so that iTunes downloads them again when doing the restore but that didn't work either.
Should I return it or wait for new firmware? Has anyone else had this problem after updating to 1.1?

Disconnect iPod and close iTunes.
Firmware files are in "Documents and Settings\username\Application Data\Apple Computer\iTunes\iPod Software Updates" folder.
You should still have the 1.0.2 files named "iPod_19.1.0.2.ipsw" and "iPod_19.1.0.2.ipsw.signature" in there if have you upgraded from 1.0.1 version.
Remove 1.1 files from the folder so that only those to files are in there.
Disconnect from network (I switched off my wlan) so that iTunes can't download the new version. Connect your iPod and do Restore, iTunes will now use the old firmware files because it can't connect to the internet.

Photoshop CS2 problems after updating to 10.4.5.?

Anybody notice Photoshop CS problems after updating to 10.4.5.?

Hello I had the same problem
I found the following information that helped me.....
Program errors occur when software conflicts arise due to an updated operating system. You can resolve these errors when you also update the driver software that causes the conflict or when you update the operating system. Program errors can also occur because of a damaged Photoshop preference file, or if there is a problem with a phone or internet connection. The Apple Disk Utility fixes file system errors that can also cause program errors.
Error "Could not complete your request..." or "Could not create a new document..." (Photoshop CS2 on Mac OS X v10.4)
Issue
Adobe Photoshop CS2 returns one of the following error messages:
"Could not complete your request because of a program error" when you try to open a file.
"Could not create a new document because of a program error" when you try to create a new file.
Solution 1:
Install the most recent update to Mac OS.
Solution 2:
Re-create your preferences files.
1. Hold CommandOptionShift when you start Photoshop.
2. Click Yes to the message, "Delete the Adobe Photoshop Settings file?"
Solution 3:
Disconnect your Internet connection.
To disconnect your Internet connection, do one of the following:
If you are connected to the Internet via a telephone modem, then disconnect from the modem.
If you are connected to the Internet via cable modem or DSL, then disconnect the ethernet cable from your computer.
Solution 4:
Use a disk repair utility.
Restart your Mac in Single User mode and run fsck -fy . For more information about the fsck command, please visit the Apple website at http:/docs.info.apple.comarticle.html?artnum=106214 .
Solution 5:
Ensure that all your drivers are compatible with Mac OS X v10.4.
Determine if your printer and video card (and any other peripherals you might have) are compatible with Mac OS X v10.4, and visit the manufacturers' websites to update the drivers.
Solution 6:
Re-create your printers in Mac OS X.
To re-create your printers, first delete them and then add them again.
To delete your printers:
1. Open System Preferences from the Apple menu.
2. Select Print & Fax, and click Printing.
3. Select each printer in the list and click the delete key (the minus key).
For instructions on how to add your printers again, see "Setting up to print to a printer" in Mac Help or search Help using the phrase "add a printer."
The one that fixed it for me was solution 6 -- re-creating my printers
I don't know why but it could be worth a try
Good luck
