HELP !!!! no wifi on 20" imac coreduo sole with Leapord

Just done a clean install of leapord (did this as the drive was full of crap) , came to the install screen where you can connect to wireless network, but it could not see any, not even mine where the router is sat in the same room, my macbook sees about 5 networks.
Tried turning airport off and back on and manually connecting to a network, but none work, even tried a simple reboot. It worked fine before the install.
Any Suggestions???

Called AppleCare support today. My problem was solved with the following steps:
1. Shut down iMac
2. Restart while holding down 'Shift' key (boots up in safe mode)
3. Once logged in safe mode, restart computer
Post restart, it recognized my AirPort card and settings.

You can go strait to SL, all you need is a retail SL DVD available from Apple for $20. The US online store has them at:

Hello:
There was an OS X 10.7 update released a month or so ago that fixed this problem. Run software update.

TS4209 When i wake up my iMac from sleep my wifi is disconnected. It also disconnects my iPad, my wives iPad, my iPhone & Sky On Demand which is connected via wifi. To reconnect all devices i have to switch off & then on again wifi on the iMac. Can anyon

When i wake up my iMac from sleep my wifi is disconnected. It also disconnects my iPad, my wives iPad, my iPhone & Sky On Demand which is connected via wifi. To reconnect all devices i have to switch off & then on again wifi on the iMac. Can anyone help?

Had the same issue and finally solved it. After the upgrade to Mavericks our 2 new Macbook Airs stopped connecting automatically to Wifi while the older machines the kids had still worked fine.
Bought a new airport extreme and problem solved. Our Airport Extreme was about 5 years old and was probably not compatible with the new OSX.
BTW this was after trying everything people suggested on this forum and a 4 hour marathon tech support call with Apple where we reinstalled the OSX.
***** to need to spend $200 but glad the problem got solved.
New extreme is also mega fast so its all good.

I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM. My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore. Connected those drives to TM via firewire and could see the drives and access them.
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc. I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads. Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system. I really didn't want to monkey around too much with my system. But are there other options to connect the new TC. Can't find info anywhere for this and called apple who gave me the info above. after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light or repair it in disk utility if it should become corrupted.
For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working. Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
Now a rant. I can't believe in this wireless age that Apple would make a product that cant join a wireless net work. The apple rep said i could return it and look for the previous TC that would join an existing wireless network. Are we going backwards?
Thanks!

Ok... it is getting a bit clearer but there are still some questions.
I connect to the internet via airport only and it is pretty fast.
I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc.
I think this is mistaken.
Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
If the computer is close it will be faster than the FIOS.
You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC. the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
Thanks again!
You cannot extend to a non-apple wireless router.
You cannot use join a wireless network because when you do the ethernet ports will be cut off.
But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
Join in the express is the only apple router that still allows an ethernet connection.
For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

I have an ipad mini 1st gen 64 gb (wifi only) and i have problem with some of my apps. These apps have lags when you play with them for a few seconds the apps are having lags are call of duty strike team, gta San Andreas and nfs most wanted.pleas help me

I'm going to guess videos buffer for a while also...
Two possibilities, one is you should close apps on the iPad, the other is your internet speed is not able to handle the demands of a high speed device.
To close apps: Double click home button, swipe up to close the apps.
To solve internet problem, contact your provider. Basic internet is not enough for video games and movies. Your router may be old and slow.

Help! I have had my iMac G5 fitted with new Logic Board but it doesn't work

Help! I have had my iMac G5 fitted with new Logic Board but it doesn't work
I have just had my iMac G5 First Gen 1.8Ghz fitted with a new Logic Board under the Apple Repair Extension Programme for iMacs.
I got the iMac home from the repairers and switched it on and everything was working fine for about 2 hours and then all of a sudden the Error Page came up on the Screen (with a big On/Off Switch Logo) and it said I had to shut down.
So I shut it down waited a few minutes and then tried to re-boot it but nothing happened. All that happended was the Power Light in the Right hand corner came on..but nothing else....
Help! Any ideas what to do please?

If you have an external firewire drive (it has to be firewire, USB won't boot on a Rev A), plug it in to the firewire port and turn it on, then boot your iMac and see if it shows on the screen.
Have you tried to hit the eject (up arrow, the last button on the top row of the keyboard) button when you boot, perhaps the repairers left a disc in the drive? Then try and put your install disc in.

Help! I have an iMac 24" OSX version 10.6.8 my iphoto is having problems. It will not open properly. All I get is the little wheel going around and around. My iphoto is iphoto'11 version 9.2.3(629.52) What should I do to make it work properly?

Help! I have an iMac 24" OSX version 10.6.8. My iphoto is having problems. It will not open properly. All I get is the little wheel going around and around. My iphoto is: iphoto'11 version 9.2.3(629.52). What do I need to do to remedy this? I recently installed InstallMac. I don't want this on my computer. I don't know how to get it off. I'm afraid that is what scrogged my iphoto. Can anyone tell me how to correct this situation?

Re: iPhoto:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Please help RE retrieval/transfer of imac hard drive to imac Part 2

Absolutely any assistance would be gratefully appreciated thank you. I am computer illiterate and I need assistance retrieving data from a imac hard drive (rest of computer isn't working) to a newer imac. Previously had received help from the forum and found out I needed an external casing (thank you again to all those that helped), but no shops near me sell them, sales person told me Sata HDD Docking (OTB) would be able to do a similar thing. I really suck with technology, so I humbly ask if any patient persons more intelligent than me could help me with some basic questions to help me retrieve/transfer data. Let me know if I need to give details. Any links to guides or tutorials welcome as well, but I tend to second guess myself and fail at basic terms often, there are probably 6 year olds with better computer skills and knowledge than me, so yeah, pity welcome, help even more so. Oh first question am I still suppose to use Migration Assistent or do I just turn on computer with old HD in dock connected?

Okay, I apologize for throwing you the following curveball - it appears the shop assistent I was talking to may not have been as knowledgeable as I had hoped, because I don't think my imac is compatible with USB 3.0? I tried putting it into the dock but nothing happened - it gave me four options, transfer from another Mac, transfer from a PC, transfer from a Time Machine (and something else) and forth option was not to transfer now.
I attempted to transfer from Mac and Time Machine options, but with both the loading dial spun for 10 mins with each with no change. So I decided to try and set up the computer anyway. The internet set up part came up but at the time I didn't know how to set it up, and now with retrospect I assume I have to set that up before I "register this computer" as no hard drive is showing onmy computer at the moment? Sorry for the sudden and strange switch in problems but now that I have set up the internet - could you or anyone else please tell me how I can register the computer details (or why the hard drive icon is not appearing assuming those things are connected - when I did fill those details out before it told me it couldn't send them now and would have to be done later?)
Sorry for being so clueless - any help appreciated.
I am looking up my imacs specs now to see if it actually can access this dock. (thank you once again)

WIFI connection from IMAC to Officejet 6380 keeps failing

Hello. I cannot seem to get my IMAC to communicate with my printer. I've installed the software twice, once from disk and once from internet. When I print test page from printer utility, the printer spools up, prints a couple of lines, then stops and hangs up. eventually I see on the computer screen that a comms failure occurred. Anybody know what I can do to solve this?
Sincerely,
JN

Describe to me your wireless setup.
What type of wireless-router are you using?
Is the iMac connected wirelessly or wired to your network?
Can you browse the printer's internal web page via Safari (use Bonjour bookmarks to find the printer and select it).
Finally, what printer are you using?

My imac is frozen with the following notice: USB over current notice. have tried powered hub, no help. have tried unplug and restart, no help. any suggestions?

my imac is frozen with the pop up notice of "usb over current notice, a usb device is currently drawing too much power. the hub it is attached to will be deactivated". have tried unplug and restart, no help. have tried power hub, no help. my wired keyboard and mouse do not work. help.

Unplug all devices including your mouse and keyboard. Now do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computer's power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.
If it starts up normally plug in 1 item at a time. You may have a defective device that is drawing too much current.

If the problem could be adware or malware, a product you may have inadvertently downloaded
to do something and then found the computer acted up, there are ways to remove those things.
However it helps to know what computer model build year and OS X the machine is running.
Then what the problem is, with detail to describe what it is doing wrong, or not doing right...
If you have odd issues in Safari browser, there are methods and descriptions here that may help:

IMac G5 (iSight) with 10.4.11: Screen always dimmed. Starts at full bright and a second later dimms and stays like that forever. Brightness controls work normally under this circunstance. Please help !!!

iMac G5 (iSight) with 10.4.11: Screen always dimmed. Starts at full bright and a second later dimms and stays like that forever. Brightness controls work normally under this circunstance. Please help !!!
Please don't tell me to adjust anything on the preferences, since I have tried all. I think it may be anoter kind of problem, maybe hardware related or anything.
I ran the Hardware repair DVD and everything was ok, but when the imac restarted the screen was very lit again, but when it went sleep, when it went awake again the screen got dimmed again. Because of that I think that the problem could be software related, but who knows. Excuse my english.

I can't see another possible answer - the longer your machine is up, the more the power supply is stressed, it protects itself by dimming the screen to lower the draw on it.

Help! Bought a used iMac (2008) and I'm trying to install quicktime but its asking me for a password and has Apple in the "Name" spot. How do I retrieve or reset the password?

Can anyone help...
I just bought a used iMac (2008) from an ebay seller and I'm trying to install quicktime but its asking me for a password and has Apple in the "Name" spot.
How do I retrieve or reset the password?
It came with the upgrade of Mountain Lion but I cannot find quicktime in the applications. When I try to install anything this Installer Password thing comes up... so I'm stuck.

I think you're slightly misunderstanding something, so maybe I'll try to chime in, even though everyone has said it in various ways.
Before OSX 10.7 (aka Lion) came out, the upgrades to OSX belonged to the Mac and not the user. Probably there was a technical legality in the user agreement that you couldn't do that, but everyone did. I could sell a Mac with Snow Leopard (or anything before that) by just erasing the hard drive, and reinstalling OSX. Then ship it to the buyer. Now, I was pretty honest as a seller, and including not only the original installation discs but also any upgrade. I would only sell a Mac if I was replacing it, so I always was getting the brand new version.
With OSX 10.7, upgrading was done online, with no disks. So the upgrades were tied to an Apple ID rather than the machine. Recently, I sold a MacBook Pro (to upgrade to a 27" iMac), which came with Lion. I had promised the buyer that it would come with Mountain Lion, but I didn't know that the upgrade was tied to my Apple ID. I made good with the buyer by sending along a $20 Apple App Store card so that she could upgrade to Lion.
So what everyone is saying here is that you need the original Installation discs or Snow Leopard disk to reinstall and wipe out the Mountain Lion that is on your Mac. It doesn't belong to you, it belongs to the seller, and without his Apple ID and password, you cannot use it. Once you do a reinstall of Snow Leopard, then you can upgrade to Lion and then to Mountain Lion. I do not believe you can upgrade directly to Mountain Lion from Snow Leopard, but I'm not sure.
If the seller claimed that you were getting Mountain Lion, then he was lying to you (or being more civil, maybe he just didn't know like I did). If you bought the used machine from Amazon Sellers or from eBay, then you have recourse through the feedback system or through PayPal. If you bought it any other way, you're on your own.

Just bought a new iMac, with Lion, for my wife. When is was wifi with her old iMac on line with it's printer, HP C6200, no problems printing. Now that it is by itself it does not recognize the C6200...It recognizes my laser hp 1012 and laser hp 6300

Just bought a new iMac, with Lion, for my wife. When is was wifi with her old iMac on line with it's printer, HP C6200, no problems printing. Now that it is by itself it does not recognize the C6200...It recognizes my laser hp 1012 and laser hp 6300 but will not print to them wanting an autenication

How is the C6200 connected to the iMac, is it via USB or Wi-Fi? If it's via Wi-Fi please make sure it's connected to the router using the printer's Network Wizard. Then click System Preferences - Print & Scan and assuming the iMac is on the same network as the printer, if it is the printer should be seen. If it's not then click the + sign and add the printer. Apple provides instructions in Printing Overview OS X Lion
