Potential fix for slow/unreliable network on Macbook Air running Mavericks

Hi all,
I work in IT support at University of Manchester, UK and have found a fix for for network issues we were experiencing with Macbook Air laptops running Mavericks. These Airs were having issues connecting to our WiFi and experiencing slow downloads, even when switched over to UBS LAN adaptors.
Anyhow, after trawling these forums without success I stumbled upon this solution myself so thought I'd share:
Basically, if you are experiencing speed/connection issues go into the 'Advanced' network settings and change the IPv6 setting from 'Automatic' to 'Link Local' and then reboot. Hopefully, after doing this you should find your speed levels return to expected levels!
Hope it works for you.
Cheers.

HT204350 Can I use Migration Assistant to transfer data from macbook running 10.7.5 To a macbook air running Mavericks? On first attempt destination machine says that os versions are not compatible for Migration Assistant.

I am trying to transfer contents from old macbook running os 10.7.5 to a macbook air running os 10.9.1 using migration assistant but the destination macobook air says that migration cannot proceed (yellow triangle) because the os on the macbook is not up to date (assuming that eans 10.9.1). However old macbook cannot be updated to 10.9.1.
Can anyone suggest a way around this please?

Try looking at this section in the Migration Assistant article.

How to fix my slow wifi on my Macbook Air?

Hello!
I have been having issues with wifi on my late 2010 Macbook Air. I have OSX 10.9.4. I notice that my wireless issues are fine if I'm within 10 feet from my wireless router. If I boot my same MBA using Windows, I have no issues what so ever and can even go outside and have great speeds. I have tried different browsers on the mac side with no change, I have also tried different networks with no change. I have used my fiancé's MBP and she has great connectivity throughout the house. So, I have ruled out a network issue and a hardware issue as the internet is fine on my MBA when using the windows side.
I do have to mention that my screen was replaced a little over two years ago and did read that some people who had repairs done to their laptops sometimes found that their antennae was not properly hooked back up, but again, I'm ruling this out because I believe I would still have connectivity issues on the windows side of my MBA?
I have done some research here and tried disabling BT with no luck. I also tried fixed 2.4 GHz and 5.0 GHz channels with no luck either. Also, in my research, I found a neat app called EtreCheck and have posted those results below. Any tips or trouble shooting I can try from here would be greatly appreciated!

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, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Slow startup issue on MacBook Air running Yosemite

Hi. My mac is starting slowly, taking about a minute. It seems to get held up in the blank screen phase after the power-on self test. It's not a massive issue but is annoying and a solution would be great. Thanks.

Hi. Anyone have a problem running a 4g stick through a usb port on a MacBook Air running Mavericks? Did you fix it? If so, how? Thanks.

I can run everything through the usb port, including another manufacturer's 4G stick. The 4G stick that doesnt work on my Air works on my son's. The only difference I can find? Mavericks!

whats it formatted as? Alas junker thumb drives fall like rain everywhere.
Do you have another stick / thumb drive you can verify your USB port with?
Stick with Sandisk or otherwise reputable memory sticks for your Macbook.
What do you mean by "another manufacturer"? Apple doesnt make thumb drives, .....no computer mfg. makes them, however HP has their name on one

Potential fix for WGM generating negative User IDs

I saw a posting back from August 2007 from "Summer is Gone", where he/she asked about Workgroup Manager generating negative User IDs (UIDs). No one responded back then and the thread is now closed, so I thought I'd contribute my experience with it today.
I had this problem on a 10.4.11 server that serves only as an OD Master. I had archived the OD database, set to Standalone, rebooted, and then restored the archive as a potential fix for some little glitches that we'd been having after 4 years of running the server.
After the archive was restored, WGM was creating negative UIDs during "Add User". I'm not certain that was the trigger, but it's the likely one.
The fix was to simply trash ~/Library/Preferences/com.apple.workgroupmanager.plist and relaunch WGM. After that, WGM once again started generating positive UIDs.

In case no one got back to you, when you use WGM to import set the "First User ID" to a positive number. WGM>Server>Import>First User Import ID
Then all users will get a positive ID.

Is there a way for my macbook air (running Lion) to access an external hard drive on my Imac (running snow leopard) specifically for Iphoto and itunes?

Is there a way for my macbook air (running Lion 10.7.2) to access an external hard drive on my Imac (running snow leopard 10.6.8) specifically for Iphoto and itunes?

Yes. For those two applications specifically there is sharing. This presumes both computers are on and connected to the same network.
In iPhoto, enable sharing by (on the iMac) going to the iPhoto menu > Preferences > Sharing > check Share my photos. You can either share the entire library or only selected albums. Now on your MacBook Air, in iPhoto, go to the same preference pane and select Look for shared photos.
iTunes has something similar. In the iTunes menu > Preferences > Sharing > check Share my library on my local network. On the other computer, look in the left column for SHARED and select the iMac. You can now play that music on the MacBook Air.
There are other ways to share files but for those two applications this is the simplest way.
Best of luck.

HT3964 My MacBook Air running on Snow Leopard gets extremely slow (almost like a hang, except if you wait about half an hr, it actually moves) after login interface. sometimes it never gets past the background. Cannot log back in.

My MacBook Air running on Snow Leopard gets extremely slow (almost like a hang, except if you wait about half an hr, it actually moves) after login interface. Sometimes it never gets past the background of the homepage, desktop doesn't seem to load. After multiple forced shut downs and left to run for hours, sometimes the desktop loads but the dock does not respond when applications are opened. The computer is then unable to shut down normally. Forced shut downs are necessary most times. Time machine backup takes extremely long, and attempts to use the time machine to bring the laptop back to the time befiore the problem arose was met with extremely slow and hung time machine function.
Please help!

There isn't much besides a failing hard drive or other hardware fault that can cause those symptoms. Run the Apple Hardware Test, or just take it to an Apple Store for testing.

HT1338 why is my MacBook Air running slow and I bought the 11 inch with all memory and turbo boost

why is my MacBook Air running slow and I bought the 11 inch with all memory and turbo boost

Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
If your browser is Safari, then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Any change?
Quit and relaunch the browser. Any change?
Log out and log back in. Any change?
Enable Private Browsing in the Safari menu. Any change?
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Again, if only Safari is involved, open the iCloud preference pane and uncheck the box marked Safari, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

My macbook air running slow even on recovery mode

My macbook air running slow even on recovery mode when I press Alt + Power it takes me to Mac os Utilities the mouse barely moves, I erased every thing on the hard drive so I can install a fresh copy of mac os but I couldn't because every time I try to boot up from the USB that got the mac os it takes for ever to load the OS for installtion, and some times every thing freeze when I'm on the Mac os Utilities mode. Any ideas of what's going on ?

Contact AppleCare or make an appt with your local Apple Store Genius. I don't think this is a problem we can help with.

I have a new Macbook Pro running Mavericks and safari consistently freezes. It takes several 'return/enter' presses to get to the page I requested. I have seen other comments and replies on how to fix (clear cache, clear extensions/plug-ins), to no avail.

I have a new macbook pro running mavericks and only using Safari as my browser. 75% of my url requests are 'hung up' and freeze. I have seen other posts and have tried to clear cache, reset safari, remove extensions, but to no avail.
Any recommendations?

If it works in a new user account, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

How can I download Micosoft Office 2008 for Mac on my new Macbook Air? I have the DVD and product key

Welcome to Apple Support Communities
You have two options:
1. If you have another Mac or PC, use Remote Disc to install it on your Mac > http://support.apple.com/kb/ht5287
2. Buy an external optical drive and use it to install Microsoft Office.
Both options work correctly. If you are going to use the optical drive once, use Remote Disc, but it will be much slower than using an optical drive connected to the computer
