My MacBook air 4 days old freezes up?

Mouse pad not working. Tried rebooting sever times. Taking it back tomorrow.

Were I not as relatively poor as I am, I would fall for it still. For now, I try to be content with older Apple products repaired by yours truly. And study them I do.
Would it be suffice to say that this a general problem that stems from the drive to make computers ever cheaper and faster?
The problem does not stem from the drive, but from selling vapourware and using cheap chinese labour and inferior components- to make every product ever cheaper, especially electronics. The base problem is globalisation and in the end unsustainable capitalist economics, not just our beloved Apple, sorry to say.
I should also inform you that my grapevine tells me the Mac Pro line may be abandoned by Apple in the near future, so I wouldn't bet on those any more. Again, sorry to say. And yes, up till now MacPros have been VERY reliable, generally speaking.
Enough with this offtopic, though.
I have good hopes your MacBook may be rescued yet; please keep us posted! Try 3 things first: 1. Zap the PRAM (hold down P+R+alt+option while starting & wait for a second chime at least before releasing). 2. Reset the PMU ( take off the power adaptor, remove the battery and then hold down the power button for at least 5"; next repower&restart), 3. Start up in Safe Mode (hold down Shift while starting up), let it run for at least 1/2 hours if it will start, next restart normally. Hope this works!

MacBook Air, 2 months old, battery can't keep power

Macbook air , 2 months old, battery cannot keep power. Using it for less than30 second, all system black out. it can be used only when plug in wire.
also battery charged very slow, 8 hours for 30%. The next day i charge another 8 hours, got another 40% so total battery is about 90% but when take of the wire, computer black out like no battery left again.

There are many third party batteries that are at best suspect. I have seen on Amazon what appear to be legitimate OEM Apple batteries which I suspect are graymarket products. You may try that at your own risk. If you purchase from Apple. you will know what you will be getting and with a warranty.
Ciao.
OWC has what appears to be a battery that will fit your MBP. They are a reputable vendor for Mac compatible products,

You need to copy everything form your old computer, or your backup copy of your old computer to your new one.
The iphone is not a storage/backup device. it simply mirrors the selected content of the computer to which it is synced.

What version of OS X are you using? If Yosemite, you need to update to 10.10.1 or higher.
In any case, start by going to the editor preferences>general, clicking this button and restarting the editor:

Hello:
I would trot back into the Apple store and have them fix the problem (or call Applecare with a warranty issue). There is no sense in you wasting your time trying to troubleshoot things on a new computer.

Mail is missing in my Macbook Air (5 days only)

Hi all,
So during the Thanksigiving break I didn't use my Macbook Air (version10.8.2). However, I continued to receive and view mail from both my gmail and yahoo accounts on both my iPad and iPhone. And, you guessed it, when I fired up my MacBook Air on Nov. 26th I was missing mail from the last 5 days, even though I clearly received mail.
1) How do I push/pull those missing 5 days into the Macbook Air?
and
2) How do I avoid this problem in the future?
Many thanks for any help!

I found the answer from someone in the Apple Community Forums:
Here's the response back and forth:

Remove both of the accounts from Mail and re-enter them, you must choose Imap as the collection method, not POP

Sounds scary. When I remove both accounts do I lose all of my downloaded email from years past? Ideally, it would stay in the computer and then when I re-enter them it uploads the missing dates. Am I dreaming?

So you don't bother to backup I assume? Are these Imap or POP accountsIf Imap did you create any local folders for storageIf POP everything is local so you MUST backup first. (Unless you have a current backup available) Then you won't lose any of your mail. FYI, Gmail is probably setup on your machine as Imap, Yahoo could be anything.

Is anyone having trouble with internet on the new macbook air and an old modem?

Is anyone having trouble with internet on the new macbook air using an old modem?
I live in NYC and have an old modem/router and keep getting kicked off the internet. I have time warner as my internet provider.

Hello there adell723,
I suggest taking a look at this article we have named Troubleshooting Wi-Fi issues in OS X Lion and Mac OS X v10.6 found here http://support.apple.com/kb/HT4628?viewlocale=en_US.
Symptom: The network connection drops unexpectedly
Your Mac may not not stay connected to your Wi-Fi network reliably.
Your Mac may stop accessing the Internet during use.
Solution
Use these steps if your computer disconnects from its Wi-Fi network unexpectedly.
Check your range to the Wi-Fi router and reduce the effect of interference.If your computer is too far from your Wi-Fi router or your environment has too much Wi-Fi interference, then your computer may not detect the Wi-Fi network properly. The easiest way to check for range limits with your Wi-Fi network is to move your computer or your Wi-Fi router closer together and make sure that there are no obstructions (such as walls, cabinets, and so forth) between the router and your computer.See Potential sources of wireless interference for more information about interference and solutions.
Try connecting to a different Wi-Fi network. If your computer works fine when connected to a different Wi-Fi network, then the issue may be related to your network router or ISP. In that case, contact the manufacturer of your router or your ISP.
If you have Mac OS X 10.8.4 Mountain Lion installed then I would recommend using Wireless Diagnostics tool which is on your computer already.
Here is the article for it and how to use it to assist with wifi connectivity issues.

MacBook Air 2013 Windows 7 freezes during installation

Hi there,
I have a new MacBook Air Mid 2013, 13" model (UK region) and am trying to install Windows 7 (via bootcamp) as a second OS.
When holding down 'Alt' and selecting my Windows boot DVD, everything goes OK but it freezes on the inital user input screen (Language selection). Using the same procedure, and same DVD in a Retina MBP, it works OK.
Anyone else seeing this behaviour / have any suggestions?

I spoke to Apple support about this and they had me create a new administrator user account, remove and recreate the bootcamp partition and strangely it worked using Windows 8 Pro (previously I was having the same issue in 7 & 8).
I don't see why it would work as my existing user account was only a couple of days old and nothing had been imported or migrated, nonetheless, it did solve my issue.
The other suggestion he made was to do an SMC reset which I had already done: -

Macbook Air 2012: intermittent, random freezes of trackpad and keyboard lasting a few seconds each

There have been a few other people to have reported this problem, but there has been no consistent solution for me on my Macbook Air 13" 2012, running 10.8.4.
What happens is this: while typing, the built-in keyboard and trackpad will suddenly lock up at the same time, randomly, intermittently, and for just a few seconds before returning to normal. This has been true through all the updates of 10.8.x since I bought the system last year.
During the freeze, one of the three behaviors occurs:
1) both keyboard and trackpad are completely unresponsive
2) both keyboard and trackpad get really slow, with high latency. Keys pressed show up much later or have to be pressed several times before registering. Trackpad is jumpy if it moves at all.
3) key gets stuck, sometimes the BACKSPACE key, which usually results in several dozen emails getting deleted or entire paragraphs, or rows and rows of the same stuck key. Pressing other keys does nothing.
I've spoken online with various other people who have the same problem and confirmed that the built-in keyboard and trackpad seem to be joined together whenever this problem strikes. You never see one freeze without the other also freezing.
Also, these commonly-recommended solutions don't work:
a) Reset PRAM. Done this many times. Does nothing.
b) Bring it in to Apple. Did this too. They replaced the keyboard and trackpad but the problem remains.
c) Clearing caches in safe mode. No improvement.
d) Removing "com.google.keystone.deamon.plist" and "com.google.keystone.agent.plist" doesn't seem to work either, even though the errors and behavior are exactly the same for me as for george.e.gonzalez in this thread: https://discussions.apple.com/message/19702976#19702976
These files do come back, though, thanks to Google Software Update. The keystone software appears to be part of Google Chrome, although I cannot confirm this.
e) I DO have Google Android File Transfer installed like one other person reported; they said uninstalling it fixed the problem. Unfortunately, that has not worked for me. Also, Android File Transfer is installed (same version 1.0.50.2266, same Mac OS 10.8.4) on an older 2008 Macbook, and it works fine, which points to something on just this Macbook Air as being the cause.
f) I don't use the Radio Silence firewall app--can't remove it.
g) I don't have the telldus device or whatever it is, so I don't have the "com.telldus.service.plist" to remove.
h) Completely clearing out /Library/LaunchAgents, /Library/LaunchDaemons, and /Library/StartupItems doesn't do anything.
i) Repairing permissions or repairing the volume does nothing.
j) Reinstalling the OS fresh does nothing.
k) I don't have an external trackpad, mouse, or keyboard for testing while the freezing happens, but the machine itself seems to be working, just not the built-in input devices, which are on the same USB bus.
l) Pressing ESC does not stop the key stuck situation, as it does for some people.
It feels to me like a hardware problem, not an OS problem, and it feels like a USB bus issue. I have noticed that when I insert USB flash drives, I get the same lock-up for a few seconds, something which my other Macs don't do.
I've also noticed various USB errors in the Console around the same time (same as george.e.gonzalez):
7/26/13 1:20:04.000 AM kernel[0]: AppleUSBMultitouchDriver::_deviceGetReport - DeviceRequest for reportID 0x0 returned with result 0xe000404f - retrying
7/26/13 1:20:05.000 AM kernel[0]: USBF: 844075.636 AppleUSBEHCI[0xffffff80157f1000]::Found a transaction which hasn't moved in 5 seconds on bus 0x1a, timing out! (Addr: 2, EP: 0)
But I'm not able to precisely correlate these errors to the pause.
Is anybody else having this problem that can shed more light on it than these other suggested repairs? This has been frustrating for quite a while, but I've had the stuck BACKSPACE key delete hundreds of emails on a webmail platform that I was unable to recover using Undo and out of the trash, and that's just no longer tolerable...
Thank you, thank you, thank you, if anyone can help me fix this!

Hi, Dan--
Nope, none of those four... I do have Dropbox but never installed it on this machine. The other three are services I've never signed up for.
I am basically using these apps up-front:
Mail.app, Safari, Notes, Terminal, maybe LibreOffice 4.0.x, maybe Sublime Text 2, Console.
And the freezes happen about twice a day, usually when I'm in Mail or Terminal, but that's because those are the ones where I'm typing the most and can see immediately when the freezes happen. It could be happening even more frequently while I'm browsing, but I might not know it because I'm merely reading what's on the screen.
This is a list from Activity Monitor of what I'm using right now, which is very typical of what I use all day:

Macbook Air Mid-2012 UI freeze

Hi there,
I have a Mid-2012 13" Macbook Air (i7 and 8GB of RAM) with Mountain Lion and all software updates (as of 15th of November) and for the last few weeks I have been experiencing some random and very strange UI freezes.
It seems to happen while browsing with Safari and the symptoms are as follows:\
- All OS UI is frozen, including option-command-esc and all dock icons, menus, windows, etc
- Cursor still moves with the trackpad as normal
- Caps lock works fine, LED lights up if you press it
The only way to recover is to shut down (long press on power button) and restart.
I have looked at the console and there are no reports of kernel panics or any other log messages that may give a clue as to what happened.
It also occurs fairly randomly (once every few days) which makes it very difficult to pinpoint the cause.
I have browsed similar threads but so far no clues, any ideas?
Thanks in advance for any input.

The next time you have the problem, note the exact times when it starts and ends: hour, minute, second.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console 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 Console in the icon grid.
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.
Scroll back in the log to the time you noted above. Post any messages timestamped during that interval – the text, please, not a screenshot.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into a message.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.

Macbook Air 2011 11" - random freezes. Roaming wifi causing it?

I have MacBook Air 11" Mid-2011 (4GB RAM, 128GB SSD, i5). Ever since getting the machine I've experienced random freezes - spinning beachball, screen becomes unresponsive, holding the power button to force it to close being the only thing I can do. The console logs don't show anything that indicates a problem. They just stop logging anything until I restart. I took it to an Apple store Genius while still under warranty and they kept it in for a few days and ran a suite of tests and found nothing.
The problem was completely random and unreproducable. Sometimes it would happen a few times in a row, then nothing for weeks. Also, it was only happening when I was staying in a particular hotel during the week for work. It was Hilton hotel with the wifi being provided by BT Openzone. It would only happen there, never at home, family members house, Starbucks (which also use BT Openzone here in the UK, airports).
I recently made some changes to my home wifi setup and the problem has reappeared, but this time at home. Where previously I just had an Airport Extreme, I have now extended the network over ethernet powerline to a second wifi access point. The second wifi access point has the same SSID as the main network.
All my wireless devices should seamlessly switch between access points as I move them around the house. Our iPhones, iPads and Dell laptop seem to have no problem doing this. When I move away from one access point, once the signal strength drops to certain point, the device connects to the second access point. The MacBook Air also does this, but it seems to freeze if I am in an area where the signals are overlapping. This also describes the situation in the hotel. The BT Openzone hotspots were spread across the hotel. If my room was in an area where the signals from access points were overlapping I would be more likely to experience the freeze.
If I look in the Wifi logs I can see messages stating that some sort of threshold has been reached and the wifi is starting roaming. These messages are always present at the time of the freezes.
Has anyone else experienced this problem? Is it something Apple would fix eventhough I'm now out of warranty? If it could be a hardware problem, would replacing the wifi card myself help?
cheers.

Macbook Air Mid 2013 - Keys freeze up now and then

Hey there, I'm getting a little bit paranoid as I'm wondering if I have a key logger here on my Mavericks installation (10.9.5) on this macbook air; but every now
and then when I'm in Outlook or some Chat client working away - suddenly - some keys stop working ! Like the Delete key does not remove previously typed
letters, or the Letter "A" stops working, then -- after 30 seconds or so it comes back!?
Do other people experience sudden keyboard freezes like this? trackpad works fine.. It's a Mid 2013 with i7 1.7GHz and 8GB of RAM.. so it has no performance
issues, as it runs outlook and some office apps. I patched up Office to the latest version too.
So very weird, my next step is Yosemite and crossing my fingers or the apple store?

Thanks tool, looks great. I will give it a go, i think you are right - it could be some errant IT tool that my company has installed, they have some terrible
Casper suite (which i deactivated), perhaps it's throwing up some Interrupts.. no clue, but Activity Monitor tells me zero.
Thanks again , will be downloading the tool shortly!

MacBook Air (Mid 2013/Mavericks) - Freezes, requires hard restart

11-inch, Mid 2013 MacBook Air.
Upgraded to OS X Mavericks in December 2013 - have downloaded every fix/patch as prompted by the App Store.
Relatively simple use pattern - word processing and web work. No bootcamp or 3rd party software, out side of Mozila products (that I am aware of).
Aproximately once every 12 hours (regardless of continuous use), the entire computer freezes. It does not take input from any input devices/including external keyboard and mouse (which I normally do not use). The only way to fix this is a hard-restart.
I have previously suffered from sleep/wake crashes, this is a new sympton of purpose the same problem?
Getting anxious as I approach my final exams - which are written on computers. Apple - which specifically targets students and technologically unsavvy customers - has created a faulty product, unfit for the purpose for which it was sold.
Any suggestions on fixing or mitigating this problem?
My only thoughts have been a link to RAM use? I don't usually browse flash-websites or keep more than one word processing window open at once.!
Many Thanks!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
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. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) on the advice of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
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.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. 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.
5. 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.
6. 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.
7. 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 (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. 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. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
