What can I do when my macbook air says startup disk is full

What can I do and where do I look to offload things when my macbook air says my startup disk is full?
Thanks

Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
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.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

Macbook pro"No Airport Card Installed"

So my macbook pro has a grocery list of problems wrong with it, it constantly freezes and shuts down on me and it has a really hard time picking up wireless internet no matter where I am. Also part of the back of it is broken (from being in the car when I was in an accident) But the guys at the apple store say that is just more of a cosmetic issue and it shouldn't hurt how it works. But it has been getting worse every day and in this past week it has been shutting down and freezing more than ever, sometimes I have to even take the battery out in order to shut it down when it freezes. But yesterday when I opened it up it read "no airport card installed", so I got on the phone with a guy I know who knows everything there is to know about macs and he told me to go under system preferences and delete my airport then restart my computer to reset the PRAM and then add another airport under system preferences I did and that worked perfectly last night and restored everything back to normal. Then this morning it did the same thing so I reset the PRAM again and it worked(which I had to do mulitple times whenever I would open my laptop back up)but then this last time it didn't work. And I cant find the airport anywhere under system preferences/network. I've ran disk utility and repaired disk permissions and nothing has worked. I'm out of town right now but I plan on taking it into the apple store as soon as I get back.

I should clarify ... I had this same problem on the old drive but only after restarting from boot camp. But an old platter hard drive is simply too slow to bother with boot camp for my needs, so I just went back to OS X only.
It hasn't been an issue since last Christmas when I first noticed it. Since then, I've had every single part of this Macbook Pro replaced except for the battery, battery cover, and back panel plate. Some components were replaced multiple times. But it's not been a problem because I haven't been using boot camp.
I really don't see how it could be a hardware issue when it only happens during restarts, not during cold boots ... and only happens going from Windows to OS X, not the other way. Could be something in a hardware check from cold boot that doesn't happen on a soft reset.
Other people seem to be having issues with their airport cards not being recognized for a variety of reasons. I suspect it's something an update will cure. Or it'll just be like a variety of other minor bugs which Apple hasn't bothered to fix yet (like the keyboard backlight not switching off under bootcamp, etc).
Thanks for testing it out on your systems. Was just curious if anyone else had seen the problem.

What do I do when my MacBook Air is running but the screen won't turn on?

I have had my MacBook Air less than a year and have been using it daily and have had no problems with it until this morning. I opened it and expected my login screen to appear as it usually does and the screen remained black. The computer is running and it is warm, but I cannot get the screen to come on. I have tried holding down the power button, charging it completely, etc. Help!

I'm not sure if this can help but I will explain the problem I had and the steps I took to resolve it. As with many reported MacBook Air start up problems reported, I went through all the reset steps recommended. It started when playing a video that the video froze with a repeated audio playing. After shutting down with the power button I had a hard time booting up the computer. Symptoms would be power on light on with blank screen or power light on with gray screen. My computer would not complete the boot sequence. Then I reset the computers PRAM, SMC and even tried booting in the verbose mode or single mode. Sometimes the computer would boot up and all was well until I did work that demanded more of the processor. On one of those times where I was lucky to get the computer to boot up properly, I then removed and apps or software that I installed that was always working in the background. This reduced the load on the processor.
From here I went to the "Finder" icon then selected "Applications". In "Applications" I selected "Utilities". In the upper left corner of the "Utilities" box I have two drive labels of which the first one was selected. Then the lower middle of the box I clicked on the "Repair disk Permissions" button. The computer did it's work and after a few minutes completed the repair for that drive. I then selected the second drive and did the same.
After this was done I started to use the computer heavily running videos and switching from site to site to see how the processor was doing. I also turned the computer off and on throughout the last 24 hours and had no problems with boot up. Videos are running without any problems. I also had no heat problems. I still use SmcFanControl.
I assume that the additional software I installed to run in the background was loading up the processor to the point of creating more problems. The repair disk feature had cleared up the software problem that was created and now my computer works fine. I do not think is was a hardware problem.
I hope this will help some of you. I have tried for a couple of years to find a solution to my problem and with many options it is difficult to find the right one.

I got this refirbished MacBook Air sometime in the last week or two. Now lately, when I turn it off or put it in sleep mode, then try to turn it on; it will take a long while to turn on or it will turn on normally. Can anyone help me?

The SIM card might not be resting properly in the tray which causes the issue. Remove pop out the SIM card, turn off the phone, make sure it's resting properly and firmly into the tray, pop it back in, and turn on your phone!
This should solve your question

Hi aaliyafrommarkham,
In order to troubleshoot this, I would recommend that you start with an SMC reset. Information on this procedure can be found here:

hi i tried installing lion onto my macbook via a usb and when asks me to chose disk it says it can't install from this usb. anyone can help me figure out how to install it if i even can.

To Upgrade to Mountain Lion... Your Mac must be one of the following models:
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)

Hi
Does your Macbook support Airplay? What year is it? Typically mid 2011 and newer Macbooks offer Airplay capability.

Is there a way to create an AUDIO alert when my MacBook Air (Mavericks) battery runs low (say 10%)?

Is there a way to create an AUDIO alert when my MacBook Air (Mavericks) battery runs low (say 10%)? I often miss the visual power percentage in the top bar, so would like an audio alert as well.

For global alerts, yes:
There is no need to do anything before the alert appears, and the MBA will not lose data should it go to sleep. If it goes to sleep at 0% you still have several hours to plug it in before it shuts down.
I wouldn't even bother displaying the percentage value.

What office program is best for macbook air 2013

what office program is best for macbook air 2013

To create some sanity here:
If you are going to share files with family, friends, and coworkers Microsoft Office is the obvious and easy (though expensive) choice.
If you are trying to save money and still remain compatible with friends LibreOffice is free and can read/write Microsoft Office files nearly perfectly.
Another free choice is Apple's iWork suite (you'll have to download it from the App store because it isn't pre-installed) Numbers, Pages, and Keynote. These programs read Microsoft documents mostly accurately but not quite as well as LibreOffice and export to Office compatible documents. But neither LibreOffice nor iWork saves in Microsoft formats by default which means you must remember to export them. That can be a problem.
In terms of ease of use I give iWork a slight edge over the other two. In terms of doing annoying things I don't expect, Office is the hands down winner.

Just bought a Macbook Air. I does not appear to be compatible with my LCD projector. What LCD projectors work best with MacBook Air?

My Cannon LCD LV-7210 projector does not recognize my Macbook Air nor does my Macbook Air recognize it is attached to an LCD projector. Yes, I do have the proper adapter.
What LCD projectors work best with Macbook Air? Does this LCD projector have auto-detect for computer?
Thanks!

I've just purchased a *27in (aluminium case) LCD Cinema Display* and am using it with my MacBook Pro, linked by the supplied three-jack cable (Mini DVI display jack).
The 27" display uses Mini DisplayPort, not Mini DVI.
But I also have *a white-cased MacBook (purchased in 2008) which has an older type of display socket*, certainly not compatible with the Mini DVI type.
The early Mac Book uses Mini DVI.
1. Is there a cable or adaptor available to link my older MacBook to the Cinema Display? Nothing in the online store looks 'right'
No. Mini DVI is single-link, and does not support the resolution needed for the 27" display.

My sister's macbook cant connect to wifi. It said that "no airport card installed". What should we do?

Help us to solve this problem.

Depends on whether or not the machine is under warranty or not. If it is, just take it to an applestore and let them worry about it. If not, your airport card may have failed and may need to be replaced. It could also be that the card needs to be reseated, which is what I would check first. Look for a guide at ifixit.com.

If You Are Locked Out Or Have Forgotten Your Passcode
iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
iPhone, iPad, iPod touch: Wrong passcode results in red disabled screen
iOS- Understanding passcodes
     If you have forgotten your Restrictions code, then follow the instructions
     below but DO NOT restore any previous backup. If you do then you will
     simply be restoring the old Restrictions code you have forgotten. This
     same warning applies if you need to restore a clean system.
A Complete Guide to Restore or Recover Your iDevice (if You Forget Your Passcode)
If you need to restore your device or ff you cannot remember the passcode, then you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and re-sync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.
Try restoring the iOS device if backing up and erasing all content and settings doesn't resolve the issue. Using iTunes to restore iOS devices is part of standard isolation troubleshooting. Restoring your device will delete all data and content, including songs, videos, contacts, photos, and calendar information, and will restore all settings to their factory condition.
Before restoring your iOS device, Apple recommends that you either sync with iTunes to transfer any purchases you have made, or back up new data (data acquired after your last sync). If you have movie rentals on the device, see iTunes Store movie rental usage rights in the United States before restoring.
Follow these steps to restore your device:
     1. Verify that you are using the latest version of iTunes before attempting to update.
     2. Connect your device to your computer.
     3. Select your iPhone, iPad, or iPod touch when it appears in iTunes under Devices.
     4. Select the Summary tab.
     5. Select the Restore option.
     6. When prompted to back up your settings before restoring, select the Back Up
         option (see in the image below). If you have just backed up the device, it is not
         necessary to create another.
     7. Select the Restore option when iTunes prompts you (as long as you've backed up,
         you should not have to worry about restoring your iOS device).
     8. When the restore process has completed, the device restarts and displays the Apple
         logo while starting up:
           After a restore, the iOS device displays the "Connect to iTunes" screen. For updating
          to iOS 5 or later, follow the steps in the iOS Setup Assistant. For earlier versions of
          iOS, keep your device connected until the "Connect to iTunes" screen goes away or
          you see "iPhone is activated."
     9. The final step is to restore your device from a previous backup.
If you can not restore your device then you will need to go to recovery mode.
Placing your device into recovery mode:
Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.
     1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the other end
         of the cable connected to your computer's USB port.
     2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the
         red slider appears, then slide the slider. Wait for the device to turn off.
          If you cannot turn off the device using the slider, press and hold the Sleep/Wake
          and Home buttons at the same time. When the device turns off, release the Sleep/Wake
          and Home buttons.
     3. While pressing and holding the Home button, reconnect the USB cable to the device.
         The device should turn on. Note: If you see the screen pictured below, let the device
         charge for at least ten minutes to ensure that the battery has some charge, and then
         start with step 2 again.
     4. Continue holding the Home button until you see the "Connect to iTunes" screen.
         When this screen appears you can release the Home button.
     5. If necessary, open iTunes. You should see the following "recovery mode" alert:
     6. Use iTunes to restore the device.
If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
Additional Information:
Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information.
