802.11n, How can I do this?

If the airport exteme base station I have is set to 5Ghz only, my macbook pro can connect, but none of my older computers using 802.11g. I am wondering if I use the 802.11n feature that is also compatible with b/g, will the connection be slower on my MBP? Basically, is the n/g/b setting (all in one) any slower than the 802.11n (5Ghz Only) setting?

I don't think G operates at 5Ghz. You have to switch the network to 2.4Ghz if you want G rated equipment to connect.
As soon as you connect any G equipment it will slow down the N equipment somewhat - but it should still be faster than G speed. The only way to overcome that it to have an N only network.
Good luck.
PS - This would be a good question in the Airport Forum

802.11n: How to connect using this feature?

I am new to Mac and was wondering if anyone can detail or point me to where I can find information on how to use or turn on the 802.11n feature.
Thank you in advance for your time.

Hi!
If you're referring to 802.11n which is the old "draft" standard than there's nothing you'll need to do. The wireless card in your machine and software on the computer is designed to connect to "n" networks as well as b/g networks.
If you're perhaps referring to 802.1 that requires enabling via Network > Advanced > 802.1x
Hope that helps.

802.11n: How can I force a wireless adapter to primarily associate to a 5Ghz radio and not to the 2.4Ghz one?

Hi experts,
I am playing with a Cisco 1142 AP. I have same SSID configured on both dot0 and dot1 interfaces. I have a test laptop and it has a Linksys dual-band wireless adapter. However the card always try to associate on the 2.4GHz. It will only associate with the 5GHz radio when I shut down the dot 0 interface. The laptop is running Windows XP SP3 and I'm using the windows wireless Zero configuration to configure the wireless. The following is the AP's configuration:
dot11 ssid Guest-Wireless
authentication open
guest-mode
interface Dot11Radio0
no ip address
no ip route-cache
ssid Guest-Wireless
antenna gain 0
channel 2412
station-role root
bridge-group 1
bridge-group 1 subscriber-loop-control
bridge-group 1 port-protected
bridge-group 1 block-unknown-source
no bridge-group 1 source-learning
no bridge-group 1 unicast-flooding
bridge-group 1 spanning-disabled
interface Dot11Radio1
no ip address
no ip route-cache
ssid Guest-Wireless
antenna gain 0
dfs band 3 block
channel dfs
station-role root
bridge-group 1
bridge-group 1 subscriber-loop-control
bridge-group 1 port-protected
bridge-group 1 block-unknown-source
no bridge-group 1 source-learning
no bridge-group 1 unicast-flooding
bridge-group 1 spanning-disabled
Is it something I can control through the AP or it's the laptop/wireless adapter's own behavior so I either need a new card or update it with a new firmware?
Thanks!

Leolaohoo,
Thanks for quick reply! My laptop is just next to the AP. There is nothing but air between the laptop and the AP.
I actually did speed tests on both 2.4 and 5 (with 2.4 disabled of course) and I got pretty much the same result: 46Mbps MAX. I don't know if it's the linksys n card is limiting the capacity of the AP. But for now I just want it to jump on 5GHz instead of 2.4GHz...
Thanks,

Just confirming, when you have the trouble, the wifi icon is grayed-out or has all bars showing? I believe you are saying that is is grayed-out - not connected to your wireless router.
I have a Mini that started to lose connection to the Internet after the 10.7.3 update but still showed the wireless as connected. If I pinged the wireless router, I would get a quarter of the packets failing to return. The router was a Netgear that supported 802.11N connections. As a test, I set it to 802.11G (54MBps) maximum and the Mini worked fine for a week - no dropouts. And for the other devices that did support 802.11N, while there was a noticeable delay with downloads and pages loading, they still worked.
As another test, I changed the Netgear router to a Billion 802.11N model and the Mini has not had a problems since. (It is still using 802.11g). So it could be your router that is causing trouble for your Mac.
Have a look at some of the More Like This postings in the right column. There has been a number of Mac owners experiencing wifi connection issues and some very good suggestions as to how to resolve their issue.

After updating my Time Capsule, I received this message on my Airport Express: This version of AirPort Utility doesn't support this base station." How can I fix this?

After updating my Time Capsule, I received this message on my Airport Express: This version of AirPort Utility doesn’t support this base station." How can I fix this?

Per chance is your AirPort Express an 802.11g model? If so, you will need to use AirPort Utility v5.6 to administer it. However, this version will not install under OS X Mountain Lion without a workaround.
The following is one of those workarounds:
Here are the basic steps to install version 5.6 under Mountain Lion using CharlesSoft's Pacifist:
If you haven't already download the AirPort Utility disk image file directly from Apple Support Download
Place the resultant AirPortUtility56.dmg file onto your Mac's Desktop.
Run Pacifist.
Click on the Open Package option. Find the disk image file that you just placed on your desktop, and then, click on Open.
The utility is located as follows: Contents of AirPortUtility56.dmg > Contents of AirPortUtility56.pkg > Contents of AirPortUtility56Lion.pkg > Applications > Utilities > AirPort Utility 5.6.app
Drag AirPort Utility 5.6.app to your Mac's /Applications/Utilities folder.
You can now run the AirPort Utility from the Utilities folder.

I have 3 different itunes accounts and would like to combine them into just one for all my devices, a macbook pro, an iphone 4S, an older IPOD, and a ver sion one Ipad. how can i do this on all devices ?

i have 3 different itunes accounts and would like to combine them into just one for all my devices, a macbook pro, an iphone 4S, an older IPOD, and a ver sion one Ipad. how can i do this on all devices ?

i had one for a long time, then when i got the ipad i didn't realize they would all still work under one so i set up the second one on that
then when i got the new iphone i put in the info for the first and main one from my mac pro and it would not work at all, and i knew it was right, then it asked me to create a new one or i couldnt finish the setup
hence why i have 3 now
hard to believe you cannot combine into one
oh well, i will just make them all accessible for all 3
thanks

HT204053 I use my iMac to help a friend with an IPAD and a different Apple ID to transfer their existing cps to iTunes on their iPad. How can I do this without the content being merged into my own Apple ID Account

I have an IMac which is my main computer and two IPads and an Ipod Nano.
Obviously we use these in sync as an when required via Itunes.
I have recommended a friend to have an IPAD2 and she wishes to load some of her existing cds into her Itunes Account.
If I wish to do this with my own, it is simple as we simply use the Imac which transfers content into Itunes.
However, my friend does not have a separate computer so I wish to load her CD's into Itunes and then sync to her Ipad without interfering with my own library and using her Apple ID.
How can I achieve this?

" how can I sync my iphone to my mac book without losing all the music and pictures on it?"
You cannot. Copy everything you want form the old computer to the new one, then sync it.
it basically says you have to erase your iphone to sync to a new itunes!
Correct Iphone will sync, or manually manage, with one and only one computer/library at a time. Syncing, or manually managing, to another will indeed erase the current content.

HT1296 I already have an itunes account on my laptop but have been setup on a mac and have songs that have not been purchased from the itunes store, I cannot get the songs from my iPhone onto my itunes account on the mac. how can I do this?

I already have an itunes account on my laptop but have been setup on a mac and have songs that have not been purchased from the itunes store, I cannot get the songs from my iPhone onto my itunes account on the mac. how can I do this?

You copy them from your old computer or your backup copy of your old computer.
The iphone is not a backup/storage device.

How can I put my mp3 files into my iTunes library? Every time I download a song from a website and try to drag it to my library, it won't add on. How can I fix this?

Back then when I had the older update with iTunes i never had this problem with trying to put my mp3 files of music into my iTunes library. Now it doesn't want to be put into the library. Once I try to drag the music file to the iTunes library nothing happens, it just keeps showing a cancellation sign with my mouse. So how can I fix this?

Hi William.
The problem is probably that the index is corrupt and you need to completely re-create it rather than rebuilding individual mailboxes. I have no idea what the situation really is now after having tinkered with the contents of ~/Library/Mail/, though, so the following procedure may or may not work.
Verify/repair the startup disk (not just permissions), as described here:
The Repair functions of Disk Utility: what's it all about?
After having fixed all filesystem issues, if any, and making sure that there’s enough space available on the startup disk (a few GB, plus the space needed to make a backup copy of the Mail folder), try this:
1. Quit Mail if it’s running.
2. In the Finder, go to ~/Library/Mail/. Make a backup copy of this folder, just in case something goes wrong -- e.g. by dragging it to the Desktop while holding the Option (Alt) key down.
3. Locate Envelope Index and move it to the Trash. If you see an Envelope Index-journal file there, delete it as well.
4. Open Mail. It will tell you that your mail needs to be “imported”. Click Continue and Mail will proceed to re-create Envelope Index -- Mail says it’s “importing”, but it just re-creates the index if the mailboxes are already in Mail 2.x format.
Note: For those not familiarized with the ~/ notation, it refers to the user’s home folder, i.e. ~/Library is the Library folder within the user’s home folder.

My Outlook/iCloud calendar invites to others appear to work on my end and sync with my PC and mobile, but when other people "accept" the invite, it will not populate/add in to their calendar. How can i fix this without turning off iCloud?

My Outlook/iCloud calendar invites to others appear to work on my end and sync with my PC and mobile, but when other people "accept" the invite, it will not populate/add in to their calendar. How can I fix this without turning off iCloud?
I am at a new office that uses Outlook (not Outlook Exchange) which does not sync with my mobile... I just got iCloud set up on my PC to sync my contacts, calendar, reminders, etc... The sync worked (not without flaws, but the other issues seem solvable... I think), so that i can now see all my appointments on both my phone and on my PC. The problem I am having is that iCloud moved all of my calendar items from Outlook into iCloud calendar and now when I send out meeting/calendar invites the recipients may accept them, but the meeting does not get added to their calendar. This is a huge problem and may mean that i need to turn off iCloud.
Does anyone know how to fix this?
Thanks!

I am replying to my own post here as I seem to have fixed the problem.
I do have some calendars that are shared. Some of those are shared with users who have time zone support turned on. So i activated time zone support on my iphone, then deleted my icloud subscription. I then signed in to icloud again and voila... problem solved.
It is a weird one as the other calendar views were always fine and when you opened an event that appeared in the wrong day (on list view), the correct date of the event was shown in the information...
one more bug in a complicated system I guess

My 2009 iMac freezes and won't run more than one application at a time - how can I fix this?

Help! My iMac has been getting worse regarding freezing, especially when trying to open iPhoto. It will load slowly, and then I get the pinwheel of death for ever, until I shutdown and try over again. It usually takes several tries, and usually overnight. How can I resolve this issue?

First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|timed? ?o' | tail | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the 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.
Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Reset the System Management Controller.
Run Software Update. If there's a firmware update, install it.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor 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 Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the View menu or the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for User, System, and Idle at the bottom of the window.
Select the Memory tab. What value is shown in the bottom part of the window for Swap used?
Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in andWrites out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard by pressing the key combinationcommand-C. Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

When I update my nano ipod I get an error message "User ipod cannot be updated. The disk couldnot be read from or written to." How can I overcome this error message.

In the iTunes window, when I update my nano ipod, I get an error message "User ipod cannot be updated. The disk could not be read from or written to." How can I overcome this error message.

Hello there dilip77707,
It sounds like you are getting this error message that your iPod cannot be read from or written to when you are trying to update your iPod Nano. I recommend the troubleshooting from the following article to help you get that resolved. Its pretty straight forward, just start at the top and work your way down as needed:
'Disk cannot be read from or written to' when syncing iPod or 'Firmware update failure' error when updating or restoring iPod
Thank you for using Apple Support Communities.
All the very best,
Sterling

My wife's nano no longer is recognized by Windows but my ipod touch is? How can I fix this?

My wife's nano no longer is recognized by Windows but my ipod touch is? How can I fix this?

     My iPod touch is always recognized by my Vista Box...using the same USB cable and port my wife's nano isn't detected anymore. Since Vista can't see the nano iTunes can't see it either. When I try my wife's nano I get the message:
     "One of the USB devices attached to this computer has malfunctioned, and Windows doesn't recognize it. For assistance in solving this problem, click this message"
     I thought her nano wasn't charged enough but I've charged it for hours and this doesn't make a difference. It used to synch like my ipod touch but it stopped working about a week ago. My wife's nano still holds songs and works it just can't be recognized by Windows. I even checked if the Apple Mobile Device app was running and it was and I stopped it and restarted it. Didn't make any difference. Any ideas?
