My iMac can't find Wi-Fi

I have used Airport Epress for years as a base station. After switching from DSL to cable, my iMac doesn't connect to the nnetwork on booting or waking. My MBA and TiVo work fine. On the iMac, I have to choose from the list of Detected networks (a lot of them). Any suggestions?

If this problem remains even after you restart your Mac, it is possible that certain Preference files related to your Mac's network settings have become corrupted. Delete them according to the following instructions. New Preference files will be created automatically. This may or may not fix the problem.
The following assumes you are using Lion or Mountain Lion, so if you are using another version of OS X please let me know which one so that I can verify their applicability to your system.
Select (triple-click) the following line:
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
Control-click (or right-click) the line, and from the contextual menu select Services > Reveal. A Finder window will open with that file selected. Delete it by selecting File > Move to Trash. You will be asked to authenticate.
Repeat with the following line:
/Library/Preferences/SystemConfiguration/preferences.plist
You will then need to select your wireless network again in the Mac's Wi-Fi menu. It should be necessary to do that only once.
Return to System Preferences and ensure your network remains in the the Preferred Networks list and that "Remember networks this computer has joined" remains selected. Other system preferences will revert to their default settings and will need to be re-selected.

IMAC can't find N network with TC firmware 7.4.1 and 7.4.2

Hello, I have a problem since I upgraded my TC from 7.3.2 to 7.4.1 and 7.4.2.
both my two IMACs can't find the TC N network, only if I downgrade to 7.3.2 they actually find and connect to the TC N network.
please let me know if the only solution is not to upgrade the firmware.
thanks
Fabrizio

Same here: 7.1.1 works but 7.2.1 & 7.3.1 do not with the same symptoms.
In fact there are now several threads reporting the same loss of internet connectivity. Happily reverting to 7.1.1 restores connectivity.

IMac can't find network printers

We have 4 Macs in the office and a bank of 4 printers all of which have been working great and connecting together for a while with no issues. However in the last few days the iMac can't find 2 of the printers. We tried to reload them through Print and Scan preferences but they didn't appear in the preferences. Checked all the cabling and hub and everything seems OK. Booted the iMac in Safe Mode and it could see them both straight away, rebooted the iMac and again they did not appear in the list, Tried to share one of the printers from a MacPro and it appeared in the list however sometimes it just won't print to it, it seems to print but nothing appears at the printer. Since then we have reinstalled Mavericks, Verified and Repaired Permissions, Verified the HD, reset the PRAM, all to no avail.
Apart from that the iMac prints to the other printers on the network without any problem and connects to the other Macs with no problems as well. We're using 10.9.4 on a 2.7GHz iMac with 8GB of memory. The other Macs can all see and print to all the printers. We are using a wired ethernet connection, not wireless.
Has anyone any suggestions as to the problem as it's becoming really annoying now.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can read it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important.

On iMac can't find scanner, how can I add it to finder or dock?

On iMac can't find scanner, how can I add it to finder or dock?
20-inch, Mid 2007,
Processor 2 GHz Intel Core 2 Duo
OS X 10.9.2 (13C1021)
and
HP C5280 All-in-One printer/scanner
Any advice appreciated
D

Thank you rk. The usefulness of image capture had somehow pased me by. To answer my own second question in case anyone needs to know, to put your printer in the dock you open printer & scanner in preferences, highlight your printer and drag its icon to the dock (in chains if necesary!)

Imac can´t find TC after upgrade

I have tried to upgrade my TC from 7.3.2 to both 7.4.1 and 7.4.2. On both the upgrades my imac can´t find TC via airport, and are not able to connect to Internet. Works OK with Ethernet cable though. My daughters macbook does not have the same issue, and has no problem finding TC after upgrade. I use this to downgrade to 7.3.2 after trying every possible option in system settings. On version 7.3.2 everything works perfect.
Some additional information:
I also have to airport express agents connected to the TC (one for airtunes and one to my printer). I also have an Apple TV connected. All are older models and does only work on the g standard. upgrading I have also had some issues with one of my airport express agents and my Apple TV.
My imac is placed almost beside the TC so there is no signal problem.
Anyone has a clue? or am I doomed to stay on version 7.3.2 forever?

Apple issued airport update. Issue seems to be solved.

IMac Can't Find External HD

I have been having Time Machine backup to an external HD which is connected via a Firewire line for some time now. The last backup was 5 hours ago. When I went to back up, it said there was no backup disk, even though it's been connected the whole time. Now the iMac can't even find the disk and it's still connected. What do I do? I have already restarted, shut down and restarted, unplugged both the external HD and the iMac, then restarted, checked all the wires, and unplugged and plugged the external HD several times. I don't understand why the iMac can't find it. Also, when I now click "Select Backup Disk" it takes me to the Airport to find wireless disks and this is not wireless. Help!

This forum is dedicated to the productivity application, AppleWorks. It is not a "catch-all" for how Apple computers work. For those type of questions the best places to start are the forums for your version of the Mac OS or your model of Mac. For you I suggest the Time Machine forum in the Category: Mac OS X v10.6 Snow Leopard.

After two hours working my iMac can't find HD

After two hours working my iMac can't find HD.
If I will try to start the iMac again, it starts showing only a white screen.
I have done all the things that apple says except format to solve the problem.
The problem stops only if I leave the computer for a while without working.
The Hardware Test finds nothing and Verify Disk says that HD seems to be OK.

If the problem with white screen apears the computer can't start even in safe mode.
Yesterday, I tryed to format HD but I couldn't because the system could not find HD. Disk Utility from Installation Disk could not find either HD.
I closed it and after 30 minutes I tried once again to open it.
The computer started without any problem like magic and all worked perfectly.
Then, my first job was to verify disk and showed that everything was OK.
Then I restarted the iMac and same problem started again...

New iMac can't find the old iMac via Ethernet

I just bought a new 27" iMac and I am trying to migrate data from my old iMac.
I have the two machines hooked together via Ethernet and have Etherenet turned on in the source iMac but the new iMac can't find the old iMac. The pinwheel keeps spinning with no success. What should I do here?

Gramps wrote:
What FireWire?
There is no FireWire port on the new machine so this is a non-starter.
Unfortunately you didn't read my post very thoroughly. You are correct, the new iMacs do not include FW however your old Mac probably does. For just that reason and more Apple makes a Thunderbolt to Firewire adapter which you can use if you opt to use FW Target Disk Mode. You can find the adapter by going to your Apple online store or Amazon carries it to. Here is the Amazon link:
http://www.amazon.com/Apple-Thunderbolt-to-FireWire-Adapter/dp/B008RXYOKY/ref=sr _1_1?ie=UTF8&qid=1366831510&sr=8-1&keywords=thunderbolt+to+firewire+cable
However as I mentioned use TM or a bootable clone with Migration Assistant. If your old Mac was using any verison of OS X from Leopard (10.5.x) on at the very least you should have a Time Machine backup!
Also use Pondiini's guide as AnaMusic suggests, it's THE GUIDE for using Migration Assistant and Setup Assistant. He has also created excellent guides for Time Machine too.

New iMac can't find photosmart 2610 over network -- HELP

Just got a new iMac 24" 2.8gig with Leopard. Most of the setup went fine, but the computer steadfastly refuses to see my printer over the wireless network. It is an HP Photosmart 2610.
I have used the same printer wirelessly with a MacBook Pro with no problem -- it found it right away, though that was with Tiger (it still worked after it was upgraded to Leopard). It also works great with 3 Windows WP PC's, two wirelessly and one via ethernet.
My Router is a Cisco 800 series and I use a Cisco WAP. The iMac had no problem connecting to the WAP and Internet.
The core problem is the iMac doesn't acknowledge that the printer exists. It doesn't find it automatically and when I direct it to the correct IP is still doesn't find it. Also, Leopard doesn't seem to have the driver for it. When I search for drivers from the pull-down after entering the IP I get a bizillion HP options including many Photosmart's. But the lowest model # without a letter in front of it is the 3300.
I then tried downloading the dirver from HP. It said it installed successfully but still didn't show the driver from the pull-down. When I tried used "other" and directing it straight to the driver it would act like nothing happened and come back to the same pull-down without the 2610 as a choice. I also tried installing HP's entire all-in-one software suite for 10.5. It installed sucessfully but also doesn't see the printer.
I tried temporarily moving the iMac and connecting it to the 2610 via USB. It suddenly found it no problem -- both the iMac software and the HP software. And it worked fine... The moment it was back via network, it doesn't find it despite it still working fine from every other device in the household.
Not sure what there is left to try. It is not an option to permanently have it connected by USB. I spoke with HP and they say that because it works from every other device. They say it is an Apple issue. Apple says it must be an HP driver issue points me back to HP. So I am left in limbo with no functional printing capacity.
I've tried searching the Internet for any reports on this but can't find them. Others seem to be successfully using the 2610, though it is unclear if others were using it via the Network.
Any help is greatly appreciated. I am beginning to wonder if HP ceased supporting the network functionality in their 10.5 driver update but I can't get an answer on this.
Thanks.

To be specific, since the Apple Printers and Faxes function does not find it in the "Default" list, I select "IP" and then enter the valid IP address that I know to be for the printer. I have tested it multiple times from other devices to confirm the IP address and even printed a network diagnostics page from the printer to confirm it. I even had someone else review it for typos just to cross every base...
It then accepts it as a "valid" IP address and assigns it a "Generic Postscript Printer." I then chose the pull down for "other" drivers. I just checked again. There is no driver called "HP IP". There are hundreds of HP drivers those. I am looking for the HP Photosmart 2600 series. But the lowest series they list is the HP Photosmart 3100 series.
Again, I have covered all the bases I can think of. The Apple site lists the 2600 series as an included driver in Leopard but it isn't showing up. The HP site lists the 2610 as "Leopard ready." I have downloaded and run the OX 10.5 HP 2600 series driver executable from HP and it says it was successful (tried several times). I also downloaded and installed the entire stupid 400-and-something MB software "all-in-one" software suite for the 2600 series from HP. You can run its own setup program indpependent of the Apple one and it doesn't find it either. When you enter the IP is says it found no printer and refuses to continue the setup. I have turned the printer on and off many times and checked all the connections. I have confirmed that the other PC's in the household are in fact seeing it at that IP...
I have spoken with Apple Tech Support ("it must be an HP driver issue, sorry") and HP tech support ("it must be a problem with your Mac because it works for others... but perhaps we can sell you a new printer that should work better" (no kidding, they actually tried to do this!).
On principle (and practical) grouns I am reluncant to get a new printer when the one I have works perfectly well for everything accept this Mac. But I am totally out of options unless someone can help.

HELP - iMac can't find system file for start-up

Hi,
My Rev. B iMac (running OS 9.2) suddenly can't find the system file. I was working in MS Word for Mac when the system crashed. Upon start-up the computer couldn't find the system and showed a flashing question mark in an old floppy disk icon.
I started from my original OS 8.5 Install disk and ran disk utilities. That fixed a problem that was detected.
BUT the flashing disk continued at start-up.
I tried to "re-bless" the system folder as described in the Apple iMac trouble shooting guide, but no luck.
All my data is still on the hard drive, I just can't get the machine to start from the hard drive -- it will only start from the Install CD.
Any ideas on how I can get it to start up?
I really don't want to reinstall OS 8.5 and then go through the upgrade to get back to OS 9.2 again if I don't have to!
Thanks,
Mike

Hi, Michael -
Welcome to Apple's Discussions.
I really don't want to reinstall OS 8.5 and then go through the upgrade to get back to OS 9.2 again if I don't have to!
Installing OS 8.5 is not needed, since there is no update available to take any version of OS 8 to any version of OS 9. An OS 9 install must start with a full-install CD; for your model, that means any retail OS 9 Install CD (white label, gold 9).
What version of OS 9 was on the hard drive - OS 9.2.1, or OS 9.2.2?
What version OS 9 Install CD do you have available?

HT3918 My iMac can't find finder

My iMac is old. 2003 runs lepoard and 85 gig and I gig memory. Problem is can't find finder ( where's finder) turned off and on to no avail hard drive is 95% full also use Iomega 450 gig portable hd!

An iMac model from 2003 that can run Leopard, so at least 867 GHz G4 (unless you are running an unsupported Leopard installation). Is it this one?
http://www.everymac.com/systems/apple/imac/specs/imac_1.0_17_fp.html
If not, you should find your specific model on this list and look at its profile page
http://www.everymac.com/systems/apple/imac/index-imac.html
That web site also provides info about hard drive replacement
http://www.everymac.com/systems/apple/imac/imac-g4-flat-panel-faq/imac-g4-how-to -upgrade-hard-drive-use-big-drives.html
An easier alternative may be to get an external FireWire drive. It needs to be FireWire, not USB. Both FireWire 400 and 800 (two types of FireWire connections) will work, with the correct cable (or adapter). FireWire 800 is the newer faster connection. Your iMac has the older FireWire 400. Most current FireWire external drives also have USB 2.0, so it will be useful with more recent computers (whether they have FireWire or not).

IMac can't find the Superdrive.

Basic problem: my 20 inch, 18 month old iMac, running 10.4.11, can’t find the internal DVD/CD Superdrive. It can’t be found with the system profiler, itunes, iMovie, Toast, etc.
If I put in a CD or DVD it goes in the slot but it does not show up on the desktop and it can’t be ejected by the keyboard.
The computer also will not boot up in the open firmware mode.
I called Applecare and we went through the usual suspects and fixes. That didn’t work so they said to take it into an apple retailer/service to get the Superdrive replaced.
The problem is: this is my second Superdrive- only two months old. The first Superdrive (original) wouldn’t burn (and I seldom burn discs) so I had to replace that in April.
I took my computer into Apple retailer MacEnthusiasts in West LA. They checked all the hardware and said the Superdrive needed replacing (they did that) and that the logic board needed replacing (they did that).
The problem is: the iMac still won’t recognize the Superdrive.
I don’t get the feeling that anything else is wrong with the computer. It will recognize an external firewire burner but not the internal burner.
MacEnthusiasts gave up and told me to call Applecare again.
Do you think I’d have better luck at a regular Apple Store?
I can burn a disc but I paid for an internal drive so I’d like a working internal drive.
What advice can you give me?
Thanks

Hi Steve,
Depends on the Apple Store, but I think that is your next step, see what happens there before going beyond that, they may very well correct whatever it is.

IMac - can't find built-in camera

Can somebody help me, please! I have iMac 14,3, Late 2013. After upgrading to Yosemite i can't find my built-in iSight camera (No video capture devices were found- system report).
Thanks in advance!

Reset the SMC and PRAM 2-3 times back to back, instructions are in iMac SMC and PRAM reset. If it still cannot be found contact AppleCare.

Just Started iMac, Can't Find HD?

OK, I just got the iMac from FedEx, totally pumped. Got it all set up, started it up, but I can't find the HD? I was a PC user, but I remember there being a Mac OS X HD linking to the HD. It's not on the desktop, where can I bring it to the Desktop???
Thanks,
Paul

Finder->Preferences->Show HD on Desktop
Awesome.

IMac can't find HP 4315v driver

After owning this iMac for years, I finally bought a printer to go with it. I installed the printer per HP instructions. The Mac instantly recognized it. I loaded the HP cd and installation was "successful".
In spite of this, the Mac can't find the driver. I contacted HP support and after walking me through their steps, was told it's a Mac problem. Using Disc Utility, I "repaired permissions", but still didn't help. Any ideas? Much appreciate the help.

PROBLEM SOLVED
**** HP and their marketing department! As it turns out, I selected "no" during a menu installation that asked to receive promotional emails. The question however was combined with installing the driver, all in one sentence. I expected by selecting "no", it was still installing the driver but making note of not sending promo emails. I selected "yes" last night and suddenly all was well. The printer works. And the promo emails should start any time too. UGH!
Thank you so much Daddy for the help. I really appreciate you taking your time to lend a hand. And yes Baby, I must agree, restarting cures 90% of any Mac problems.
Mac on everyone!
