Macbook Air Extremely Slow Wireless
Hello All,
Got my brand new MB-Air and from the get-go noticed extremely slow wireless performance. I did a bit of digging and here is what I found.
The MB-Air works OK with cheap (consumer) wireless APs, however when used in conjunction with the commercial APs most of which use the Atheros chipset the performance is horrible. I found that when connecting to APs that use Atheros' commercial chipset, the MB-Air connects with 802.11 G specs instead of N even when the signal metrics are excellent such as -39 RSSI.
Moreover, even With the 802.11 G connection at 54Mbps the performance is both sluggish and latent. Small file transfers have a 50/50 shot at working and large file transfers seem to die reliably. Albeit this could be an issue with Apple's implementation of SMB / Samba which is rather poor.
I have tried to turn off Bluetooth to see if my experience is different. We'll see.
I would be interested in feedback from people who are also experiencing the same poor wireless performance to learn the chipset of the AP they are having issues with.
By-the-way -- I will take a fix, if someone has come up with one. However my guess is that this is an engineering issue that Apple has to fix.
BP
Sitting side-by-side, my MBA was averaging less than 1 Mb/s on downloads, and my MBP more than 9 Mb/s. The MBP was fully ten times faster. As you can imagine, viewing videos was a ragged, unpleasant experience on the MBA.
I'm using an early wireless-N Belkin router, so it didn't show up on airport utility, thus i couldn't change channels there as proposed on this thread. But to isolate the problem, at my brother's suggestion i took both computers to a Starbucks, and observed the two computers downloading there at equal speeds. So clearly the problem wasn't with my MBA, but my router.
I went to Belkin's website to figure out how to change channels on the router, and checked for firmware updates. There was one, so i figured I'd do that before attacking the "changing channels" task. I upgraded the firmware, and with that simple fix my MBA is happily zipping along now with >9 Mb/s downloads, same as the MBP. More than TEN times faster than before. My iPhone download speeds increased more than tenfold, too.
My advice, if you're having wireless problems with your MBA: First make sure your router's running the latest firmware.

Macbook Air Extremely Slow/Stuck
Dear all,
A few months ago my MBA was still logged on when the battery went empty. I charged it completely, but then it was extremely slow. Sometimes it was just stuck. I then used the power button to shut it down completely. After that my MBA never starte up again: it remained stuck at the start-up screen (spinning cogwheel and mac-logo). I asked the distributor to re-install OS X. Fortunately the distributor was willing to do so. Re-installing OS X helped.
Yesterday the same thing happened. Obviously I don't want to go through this again so I am waiting very patiently for programs to load. Sometimes this takes up to 20 minutes. (I should add that sometimes it works very smoothly). Clearly, this is not very functional. Does anyone have an idea what to do? I need my mac.
One thing I may have done wrong: I renamed the computer name into my name; Thijmen. I used the uppercase T, which I shouldn't have, according to what I've read after changing the name.
I hope someone knows what to do with this.
Kind regards,
ThijmenI went through the same issue with changing the main user's name while not realizing what the terrible path ahead would be, but I never had startup issues personally. newer MBAs should be starting up on a dime, so obviously you have a serious problem that can't be solved easily at home.

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. -
My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Furthermore, when just using safari to watch streaming television, my computer gets really slow, and locks up, and the dock appears blank and I sit here frustrated. Anytime i wake up my computer, my keys don't respond and I've waited at most 3 minutes untill i can type in my password. Even sometimes when i type in my password and hit enter, it takes forever to open up my mac. I have barely used any storage in my macbook, since i only use it for college, and I have run clamscan wiht no viruses showing... Any ideas?

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, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in 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, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test. -
I am having trouble transferring files from an old MacBook (2007) to a MacBook Air over a wireless network. The connection was interrupted and the time was over 24 hours. Is there a better way to do this? I'm using Migration assistant. The lack of an ethernet port on MacBook air does not help.

Why is my macbook air so slow?
why is my macbook air so slow?
First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the system log for messages that may indicate a hardware fault. 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. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|nspace-h|n Cause: -' | tail | open -ef
Copy the selected text to the Clipboard (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).
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.
Reset the System Management Controller.
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.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
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 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 System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes 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 (command-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. -

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.

Extremely slow wireless xfer from Macbook to USB drive on Airport Extreme
I have tried to set up my external 1TB seagate USB drive to my AE for wireless network storage (only 1 computer on network, but I also have an AppleTV). If the drive is connected directly to my MB the transfer speeds are fine, but when I try to go wireless the speeds are extremely slow - to the point of unusable. I am sure these issues have been discussed previously, but I cant find an obvious solution. Is there anyway to run network diagnostics to see what my MB->AE transfer speeds are and what my AE-WWW speeds are? I dont recall the cable bandwidth that I get from Time Warner - but it is one of the faster options.......

There are at least two explanations for this: (1) Your wireless connection is like to be slower than a direct USB connection. (2) Apple base stations are quite when serving connected disk drives. One reference cites 10-30% of the speed of a directly-connected USB drive.
I dont recall the cable bandwidth that I get from Time Warner - but it is one of the faster options.
I wouldn't expect that to be a factor in the performance you're seeing. -
MacBook Air painfully slow after Yosemite update
Dear all,
I've updated my Macbook Air (2011) to Yosemite in order to make it compatible with Apple TV.
Since doing this everything is VERY slow, not just slightly slow but VERY slow.
I was advised to buy more memory - but it doesn't seem possible to purchase extra memory for a MacBook Air.
I would really like to take a step backwards and change back to my previous OS - is there any way of doing this?
I don't mind not using Apple Tv with my Mac as long as it goes back to working normally.
Thanks and sorry if this question has already been posted.Hi,
I ran Etrcheck and this is the result :

I don't see any of the usual software suspects associated with slow downs. You don't need the Seagate software, you should uninstall that.
Reset the SMC Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support and PRAM How to Reset NVRAM on your Mac - Apple Support
You only have 2GB of ram and could upgrade to 8GB, but Snow Leopard should run ok in 2GB.....not great but ok.
Start up in Safe Mode OS X: What is Safe Boot, Safe Mode? - Apple Support be paitient as it will take awhile to start as it checks and tries to repair any problems with the file system. Once it's completely started up you can restart normally.
Insert your Snow Leopard disc and restart while holding the C key. Run Disk Utility to repair the hard drive and permissions. While in Disk Utility check the SMART status of the hard drive, anything other than Verified indicates a problem with the hard drive.
Again, you only have 2GB of ram.....try restarting your Macbook every day.....it's been running for almost a week now. -
Extremely slow wireless printing with HP Photosmart Premium C309g-m
I'm seeing extremely slow print speeds when printing wirelessly from a Mac or a Windows XP system to a new HP Photosmart Premium C309g-m printer. The printer begins printing immediately when I request a print, but it only prints one line. It will then take about 15 minutes to print the rest of the page, printing each line after a very long pause. Demo page printing doesn't exhibit this problem, only documents from programs like Word 2008, Safari and Firefox (tried firefox on PC and Mac) are affected.
If I connect to the printer through a USB connection it prints fine, so this problem appears to be with wireless printing only.
Printer: HP Photosmart Premium C309g-m
Computer: Mac mini (Late 2009 model) (also tried a Windows XP laptop as a comparison, using latest drivers from HP's website)
OS: Mac OS X 10.6.2 with all available updates installed
Computer connection method: Wired Ethernet connection to wireless router
Printer drivers: version 2.2.1 (Apple supplied, HP drivers never installed as system shipped with 10.6)
Wireless router: Apple TimeCapsule (Early 2009) 1TB, running in a/n and b/g modes on 2.4 and 5GHz. TimeCapsule is in bridging mode as the DSL modem handles DHCP service
Encryption: WPA2 Personal, no MAC filtering or hiding of the SSID.
IP addressing scheme: All addresses are handed out by DHCP server with no reservations of any kind
The TimeCapsule is sitting three inches from the printer and the printer indicates full signal. Connection of the printer to the wireless network and setup of the printer on the Mac went without a hitch. Only when printing a test document did we discover the problem. The wireless network is behaving as expected when accessing the Internet from both Mac and Windows devices (tested with a Dell laptop running XP and a MacBook running OS X 10.6.2), so I don't see any overall problems with the wireless network.
Attempted remedies:
1. Rebooting and powering off, waiting, powering on computer
2. Resetting the print subsystem, turning the printer off and on again and reinstalling the printer
3. Unplugging power from the printer and letting it sit for several minutes before trying to print wirelessly.
None of these worked.
This question was solved.
View Solution.I don't think there is anything wrong with the DSL modem HW. There might be an issue with how print data is being routed though.
Please try the second experiment where you blank-out the default gateway and DNS entries from the printer's internal web configuration page. Open the printer's internal web page by browsing to its IP address. Select Networking and then Wireless (802.11). Under the IPv4 Configuration tab, select Manual IP:
For Manual IP Address, use the existing printer IP address.
For Manual Subnet Mask, use 255.255.255.0
For Manual Default Gateway, leave blank. This is important.
Select Manual DNS Server:
Leave both the Manual Preferred DNS Server and Manual Alternate DNS Server fields empty. This is important.
Press Apply.
Turn off the DSL modem, the printer and all computers connected to your network. Wait 60 seconds then turn on the DSL modem and then turn on the printer. Then turn on the computers. See if this corrects the printing speed.
