Mid 2012 MacBook Air Yosemite Slow Booting and Old Boot Screen

Hello Guys,
I have a mid 2012 MacBook Air 13" and I had installed public beta of Yosemite on it. Now I am running OS X 10.10 (14A388b) and I have problems on the boot. On all the other macs, I saw that the booting screen is black background and a white Apple logo on it. But on my mac, the booting screen is same as Mavericks and for the first 5-6 seconds, the Apple logo doesn't show up. And the mac is booting very slowly. Also, Continuity and Handoff are not working properly. What might be the problem?

What is apple doing about numb fingers using the trackpad on the new mid 2012 macbook air?

What is apple doing with the trackpads on the mid 2012 MacBook Air, that creates numbness and pain in my fingers.

You have no idea what you are talking about catperson. This topic happens to be on one of the
Apple Support Cummunity conversation. It's called,
Hands go Numb, tingle from trackpad-
Do you even have a 2012 or newer laptop? If not, don't give advise as simple as go see a doctor. Will Apple be paying for my medical bills?
Yesterday is the first time my finger got so painful I could no longer work on my project. I iced it to help numb the numbness, usally the pain subsides when I stay off my laptop for hours however when I start working on it the pain returns and you need your index and middle finger to work that laptop. This is the first time the pain had not gone away, 24 hours later. It feeIs like the tip of my middle finger has a giant splinter in it, very sore! I bought the first edition Macbook Air laptop 4 years ago and never had this problem with my index and middle finger, until I started working on my new Air.
Look at how many people are having the same problem. It can not be a coencidence. This problem has cost me the use of my finger and the high expense for this new MacBook Air. I'm going to my apple store tomorrow and show them how many people have this problem with numbness. I think this problem goes way beyond giving me a refund for this computer.
Any thoughts after reading other people having the same painful experience?
So What is Apple going to do with the new MacBook Air trackpad that creates numbness in your fingers?
PS: I know the trackpad is made of glass, so I covered my trackpad with a clear cover they sell to put on iphones however that did not slove anything.

Mid 2011 Macbook Air Painfully slow.

Mid 2011 Macbook Air Painfully slow.
Hey everyone. I am writing about my 13 inch Mid 2011 Macbook Air.
Recently it has been extremely slow and on occasion has not started up.
I have reset the PRAM and SMC already, yet it is still very slow. I have a couple theories about what might have caused it, are they plausible?
Theory 1: It’s a software problem. I tried to upgrade to 10.8.2 but halfway through the upgrade the computer restarted and somehow I was still on 10.8.1. For fear of a big issue happening I didn’t try to upgrade again. Perhaps it is a flaw in Apple’s software update?
The important thing to note about this update is that I tried to install 10.8.2 around a month or two weeks BEFORE I started having problems. So if these issues were due to 10.8.2’s failed update then it certainly was a delayed reaction.
I would of course like to update to 10.8.2 BUT as my computer is acting EXTREMELY slow and having trouble turning on occasionally I am worried the software update will completely brick the machine. Is that possible? Should I actually finish through with the software update?
Theory 2: It was an electricity problem.
The computer died when I was sitting at a café plugged into their wall sockets. A few days later when I came back to the same spot with my old macbook which is now being used in lieu of the Air it suddenly turned black for a little while. Sensing it might be an electricity surge or something with their system I unplugged the cable. I am not sure if that was paranoia though.
Can an electricity surge or a bad outlet fry a computer? Can it fry the ram so the computer is extremely slow? Does that theory hold any water?
Thanks for your help diagnosing this problem.
All the best.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
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.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Copy or drag — do not type — the line below into the Terminal window, then press return:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.) You can omit the final line ending in “$”.
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}'
This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}'
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null
Remember, steps 1-5 are all drag-and-drop or copy-and-paste, whichever you prefer — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Mid 2012 MacBook Air: fan won't run faster when overheated

mid 2012 MacBook Air, system (tried Mountain lion/Mavericks/Yosemite, all have the same problem)
WHAT HAPPENED:
The other day I was watching some flash video on the couch, and I heard the fan running like crazy. The laptop shut off 2 seconds later-- no warnings, just black out all of a sudden. (ps: I usually use it on the desk. Only used in bed/couch for a few times)
It won't start if I press the button immediately afterwards. Instead, it will restart itself after a few minutes, no matter what.
I shut it down and let it cool down for about an hour. From then on it wouldn't last more than 5 minutes when used heavily (Facetime, chrome together) and about an hour when used lightly (only one app like chrome). Then it shuts off without warning like before. The laptop felt really hot, and I couldn't hear the fan.
The battery drop down menu says "service battery", and doesn't disappear after a few restarts.
WHAT THE APPLE GENIUS SAID:
I took it to the Apple Store the next day, a genius ran a hardware test, and it showed no problem at all. After the test and restart, the "service battery" warning was gone too.
The genius said it seemed everything is ok. The battery only ran 159 cycles, and it's supposed to last 1000 cycles.
But he doesn't know why the laptop would shut down out of nothing. If we had apple care, they could bring it back and stress it out, to see whether it shuts off and find the problem. I just brought it home to see what happens.
WHAT I TRIED:
1. Max CPU: the fan doesn't react, still runs at 2000 rpm.
2. Hardware Test:
          when the laptop is hot, it won't survive the test, shuts off during the test.
          when it's cool, it passes the regular test in 1min30s, showing no problems.
          when it's cool, the extended test cannot last 3min before it dies.
3. Fan test, it can run at maximum speed. In this case the CPU temperature will drop quickly.
4. The Enclosure Bottom, Memory Controller and the Mem Bank temperature doesn't seem to change. (I don't know if they are supposed to be that way...)
Please give me some advice about what you think the problem is, and what I can do about it. Thank you all so much!

If it didn't show any problems in the Apple Store, maybe its your ambient temperature? Although even this shouldn't cause your machine to behave the way it is currently. You need to record it or something then show Apple the issue.

Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

I have a Mid 2011 Macbook Air.
Upgraded to Yosemite last week.
Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
Thanks,
John

Hi!
I have exactly the same problem, and I can't find any solution.
I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
Any suggestion is greatly appreciated!

Macbook Pro Mid 2012: Issues with Yosemite update, graphics, and hard drive.

MacBook Pro (15-inch, Mid 2012)
Processor: 2.3 GHz Intel Core i7
Memory: 4 GB 1600 MHz DDR3
Graphics: Intel HD Graphics 4000 1024 MB
I've used 192.8 GB
Operating System: 10.10.1 (14B25) YOSEMITE UPDATE
I've been experiencing problems with my Macbook Pro shortly after the two year mark of when I've purchased it. There are a few things that are going on. I recently verified my Macintosh HD disk through disk utility and it stated in red that there was an incorrect number of file hard links & then error: This disk needs to be repaired and to restart and then press "R". However, everything before that seemed to have passed. I have everything backed up on an external hard drive and use the time machine frequently. Another thing that has been happening, usually when I'm opening one my adobe programs, is that my screen will go white for a minute along with unidentifiable pink glitchy shapes that don't move. My computer has not been running like it used to and is running slow, freezing, and periodically going white --- as I just mentioned before. I just know that something isn't it right. I've been having to restart my computer by manually pressing the power button more than I've ever had over the past two years. I always work on my computer on a hard surface in a cool area & my fans seem to behaving okay. I also recently installed the Yosemite update for the mac sometime during this past November too and noticed slower running speed, more freezing, and longer times to boot up afterwards. Please speak up if you're experiencing problems with your 2012 Macbook pro too and especially after downloading the Yosemite upgrade. I don't see how it's in any way acceptable that I should have to deal with issues pertaining to my graphics card. Sorry for this post being a little all over the place.

Hello brousch,
Thanks for using Apple Support Communities.
From your post I see that your Mac is spontaneously restarting whenever you see a certain animation on your screen. This indicates your Mac is getting a kernel panic caused by that animation. If you'd like to learn more about kernel panics, including how to troublshoot them, please take a look at the information in the link below.

Mid-2012 Macbook air wifi connectivity, bluetooth interference, and SD slot

I've had issues with all off these things since right around the time my warranty expired:
-Wifi is often slower than all other computers in my house no matter where it is; it doesn't work at all if i have bluetooth on and connected to something. this seems to be a known bug that apple won't acknowledge- there are discussions of it here and on macrumors forums
-The SD card slot often ejects or unmounts the storage expansion that I keep in it full time. not just when battery is low or even while sleeping, but sometimes while I am sitting at the computer working. I've had to repair the sd card with disk utility multiple times as a result.
-Battery life is down to about 3 hours- battery health says it is at 83% of its original full capacity but I know it used to get 6 hours easily, and mavericks was supposed to improve that. I'm wondering in part if the SD card is part of what's killing it, but there is no way I can find to really get a deeper analysis of what's using the power. I do nothing on my computer except use office applications, browse the web and listen to music through headphones or a wired speaker (since BT won't work with the internet).
Mid-2012 13" MBA, running 10.9.4. I have no pirated software on here and have been gradually moving things to cloud storage, so the hd is only 54% full. I'm going to have to pay for a support ticket to get any help on these things, so i'm wondering: Is it worth it? Will I end up paying for every separate issue? I feel pretty confident Apple support is not going to acknowledge the first two points are part of larger and unacknowledged issues, especially being out of warranty, and battery life is so subjective.
I'm honestly feeling close to buying a windows 8 machine.

I have seen lots of issues on Yosemite with Wifi (and have been having issues myself), but yours seem different. It is a pretty new computer, have you tried taking it in under Applecare (if you live somewhere this is convenient)? Maybe you just got a defective wifi card. I won't defend Apple over this wifi mess, because it really is terrible, but your issue seems not the same as the ones I've read about while researching how to fix mine (unsucessfully....).

My mid 2011 MacBook Air has slowed down significantly overnight?

Last night my MacBook Air was working fine.
When I went to use it this morning, it has slowed down significantly. It takes awhile for it to respond to trackpad movement or the keyboard. Opening finder is delayed now, opening any app is delayed now. Booting it back up takes extra long now, probably around a minute compared to thirty seconds before.
I've tried an SMC reset, repairing the disk and repairing disk permissions.
From what I can see, the hardware doesn't appear to be failing, but I could be wrong.
Can anyone help me out? What could possibly be going on with my MacBook? How did this happen overnight?

Your MacBook Air's memory is not upgradable, and as you already determined unused storage capacity is not a relevant factor.
There are many reasons a Mac may be performing slower than expected.
Back up your documents and everything else important to you before proceeding.
To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting:
Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red.
When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:

Etrecheck will be in your Downloads folder. Open it from there. You may see the following dialog box:
Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.
It will take a moment to run as it collects its data.
Copy and paste its output in a reply.
Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.
EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
After completing the above please determine if the problems also occur in "Safe Mode":
Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
You must disable FileVault before you can start your Mac in Safe Mode.
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.

Mid 2012 MacBook Air Troubles (Random Reboots & No Camera)

Hello, I'm hoping somebody can help me out. I have a mid 2012 Apple MacBook air that I am having problems with. Ever since I bought this laptop from my friend, it has randomly rebooted during sleep mode, and the FaceTime camera has not worked. I was told that water has been spilled on it at one point, but I have went over the entire computer and do not see any sort of damage. Because I was not having any luck getting it to quit the rebooting, and because the camera would not work, I purchased a replacement motherboard and battery.
The new parts arrived today, and I quickly installed them. I was instantly having the same exact problems. The computer will still reboot when I close the lid to put it in sleep mode. It instantly starts rebooting after about 2 to 3 minutes. And it will continue to reboot over and over until I reopen the lid. In addition the camera is still not detected, and I have double checked under the system properties that it is not showing up under the USB tab. I have cleared the PRAM & SMC, still no changes. As a last ditch effort, I decided to reinstall OSX 10.9 Mavericks as a fresh install. No go...
Does anyone have any ideas of what I can do to get this thing running properly? I bought it because I wanted to use it for some home-video editing, and in its current condition I don't feel that it is trustworthy. The only things left that I can replace, would be the display or the thunderbolt daughterboard. I already previously had replaced the SSD with a larger 256 GB, and I tried swapping out the wifi card as well. I'm banging my head against the wall here, and really want to be able to use this computer. Any help would be greatly appreciated!

Unless you get the answer you need here, I would contact Apple MacBook Air Support or an Apple-Authorized Service Provider for service.
Apple Service Technicians have access to all special tools, test equipment, parts, and proprietary data needed for efficient repairs. If cost is your issue, you can ask for an estimate before they proceed with any needed repairs.

Apple TV & Mid 2012 Macbook Air 11.6'' - AirPlay not working

So I just purchased the new MBA to replace my 2010 air...which also suffers from a cracked screen. Since mirroring wont work on the old model anyways, I sold the unit and cut my loses (I was going to replace to LCD but decided it wasn't worth the effort.)
Anyways...
I attempted to use the MBA and the mirroring function out of the box and it worked great. Sure the mouse was a little sluggish, and the audio obviously delayed (on the MBA), but synced perfectly to the TV. I watched YouTube videos, and some other flash and HTML5 embeded content. I was prompted for an update for my Apple TV 3, and today for my MBA. After updating, and restarting both units (which I have done several times since then too), mirroring does not work as it should.
When I select the TV usually it would adjust to a resolution higher than the MBA native resolution--but appropriate for the TV. Instead, the MBA screen goes blue, adjusts to the resolution, and then goes blue again, returning to a non mirroring mode.
Sometimes when I do get mirroring to work--at the MBAs standard resolution--AirPlay will be "working" despite it saying that mirroring is off and greyed out.
The biggest frustration out of all of this is that whenever I go to play a video, assuming AirPlay doesn't stop mirroring at whatever random resolution it picks (I have adjusted between a fixed and aspect appropriate setting), the AUDIO will only play through my televisions speakers, and the video will stop feeding and go back to the Apple TV home screen.
It has done this with YouTube, HBOGO, Hulu, and a number of other video streams online.
Has anyone else had this issue so far?
To reiterate:
Using mid 2012 MBA on OSX Mountain Lion
Apple TV 3 will stream audio and mirror sometimes, but stops mirroring whenever video is played.
AirPlay icon will remain available, but will say mirroring is unavailable / greyed despite it actually "working."

Hey thellamaPod,
Thanks for the question. The following resource provides troubleshooting information for AirPlay Mirroring in OS X. Usually, this may be caused by the firewall and a simple tweak of the settings should resolve your issue:
About AirPlay Mirroring in OS X
http://support.apple.com/kb/HT5404
Firewall security settings
If you use a firewall, make sure the following firewall security options have been set to allow AirPlay Mirroring to work:
1. Choose System Preferences from the Apple menu ().
2. Click Security & Privacy, then click Firewall.
3. Click the lock icon to unlock it if it's locked, then type an administrator name and password.
4. Click Firewall Options.
5. Deselect (uncheck) the “Block all incoming connections” checkbox.
6. Select (check) the “Automatically allow signed software to receive incoming connections” checkbox.
Thanks,
Matt M.

Mid-2011 Macbook Air - very slow wifi yet with OSX 10.9.2 (The Return)

Referring to this previous post:
https://discussions.apple.com/thread/5911893?tstart=0
Problem remains the same, wifi is simply impossible to use in OS X, and my "solution" to avoid throwing my Macbook Air into the rubbish bin is keep using Elementary OS (an Ubuntu-based linux distro). It basically saved my life. I think my last try will be 10.9.3, and if it doesn't fix the problem, I will quit OSX for good.

Please take all the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Run Software Update and install all available updates for OS X or your computer's firmware.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it (not applicable to OS X 10.9 or later.)
Step 4
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 5
Reset the System Management Controller.
Step 6
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Mid-2012 MacBook Air WiFi Reconnect-Partial Solution

The MacBook Air seems to have some significant WiFi issues for a lot of users. My issue is as follows: the MacBook will connect to any compatible WiFi hot-spot with no problems, and it will maintain the connection almost always. The problems come when I try to reconnect to the internet over the same WiFi hot-spot after waking up the MacBook. Even more frustratingly, the problem is not consistent. Sometimes it works, and sometimes it doesn't. After some investigation, I have come to the conclusion that reconnection problems happen when:
You wake the computer up from computer sleep (not display sleep or Power Nap)
You are using a specific cable modem (the one I tested on was a Motorola SURFboard SBG6580 DOCSIS 3.0)
You have not restarted your cable modem while your MacBook was asleep
The MacBook Air will connect to the WiFi network (i.e., it can access other devices in the wireless LAN) when woken from computer sleep; it just will not connect to the internet
The only way to get the connection back is to restart the cable modem. Restarting the MacBook, restarting your WiFi base station (in my case a brand new AirPort Time Capsule tower), having the MacBook forget the WiFi network and then reconnect--all do not work. But if I just restart the cable modem, the MacBook connects with no problems. This is a problem specific to the MacBook Air because none of my other devices ever have a problem connecting to the network after waking up from sleep (including a Lenovo ThinkPad E530c). As has been proposed in some of the many discussions about MacBook Air WiFi issues, I think it has to do with the bleeding-edge power saving modes that the MacBook Air enters in to when it goes to sleep. Apparently, the computer sleep mode will cause it to not be able to reconnect to the internet, so it seems to be some sort of incompatibility or bug between the MacBook Air and the cable modem--in my case, the Motorola SURFboard.
So that's the problem, but I do have a partial solution while the engineers figure out a fix. Set the System Prefs > Energy Saver setting on the MacBook to never go into computer sleep (I set it only for Power Adapter, not Battery). In my case, this is a workable solution because I have my MacBook Air plugged in at home almost all the time. I have lived with these settings for a couple of days now and whenever I wake up my computer, it still has the internet connection and works as expected. And if for some reason I don't plug it in and it goes into computer sleep, I don't waste time troubleshooting. I just restart the cable modem and after a minute or so, the internet connection is re-established. I'd be curious to know how many cable modems this happens with, and if anyone has a fix having to do with cable modem settings (the Motorola SURFboard, to my knowledge, doesn't have a web app interface to tweak settings, perhaps because my cable company doesn't want me tweaking things, but I frankly have not spent any time researching that end of things).
Hopefully this will help some MacBook Air owners (is this an issue with MacBook Pros?) that have this problem.
Good luck!

Have the same problem. Was OK for nearly two years then started two days ago.

Kernel Panic on 13" Mid-2013 Macbook Air Yosemite

I received a refurbished 2013 Macbook Air a week ago. Every so often, mostly commonly when browsing the web, the Air will crash, give me the "The computer encountered a problem" splash page, and need to restart. Sometimes multiple times a day. I understand it might have to do with my browser (FF 35) taking up too much memory, especially when running flash players, but I want to be sure that it's not a hardware issue. Here's my most recent panic report from this morning:

Mid 2012 Macbook air battery charging erratically

A few days ago, I noticed that my macbook air was not charging even though it was plugged to the power adapter. After some time, it showed that it was charging, but infinitely slowly. I did SMC reset and after a while, it was charging normally. But the problem reappeared some time later. Some times SMC reset seems to help, some times it does not. Some times it says that the battery is charged, while the battery percentage is showing less than 100. Also, the connecter light is also not synchronous with the battery state sometimes.
I had changed the battery a couple of months ago. The power adapter is also new. Also, I some times hear a very low buzz sound coming from the connector of the adapter.

Assuming you have the tools required (two different screw drivers and a plastic tool to lift the connector from the logic board) you will save about $30. If you don't have, or don't have access to the tools you'll save almost nothing. However, depending on your source you may wind up with a counterfeit Apple battery, a used battery, or a battery that may or may not be truly Apple compatible. Take it to an Apple Store.
