  • Bad to let Mac Book Air Fan run full speed all night?

    I ran a full Diagnostic test overnight on the "Full Test" mode and little did I know the fan ran at max speed for 6 hours.  There were no problems detected but is this bad for the fan?  The computer was warm but I shut it off.
    Thanks

    I wouldn't worry too much about it. You will likely put your Air through a whole lot more many times over than a little six hour session with the fan going at high RPM.
    The fans themselves have not had much of a history in many years, and that's probably very good. Not sure about the air, but many macbooks use Sunon MagLev (Magnetic Levitation stabilization) fans that really make the bearings last a long time, usually exceeding that of the rest of the machine. I know it's a Sunon fan, and has a similar part number as compared to others which are definitely MagLev.

  • My mac book air says that I have over 20gb of other space used.

    How do I get rid of it I tried to turn off the time machine and other sudo commands and nothing seems to work.

    "other", refers to things that can't be categorized in the other sections of Lions storage display.  "Other" contains the operating system, system files, and other random things that vary among users.  20gb in the "other" category is very minimal.  Leave it be unless it grows larger.

  • Mac book air.  its startup disk is jammed full.  frozen

    my assistant has a mac book air.  its startup disk is jammed full.  I was able to access iphoto so she could delete some files.  The computer wont load the dock so i can empty the trash.  what can I do to free up space and get the machine running again

    Then you're in luck. Start the MBA in target disk mode and connect it to the MBP with a Thunderbolt cable. The internal drive of the MBA will mount on the MBP as if it were an external drive. Copy some of the files, then delete the originals. You should have at least 9 GB of free space when you're done, preferably much more to allow for expansion.

  • I have a 2nd gen Mac book air with Lion. The hard disk has filled up even though i keep my data , music etc on hard drive . I used disk inspector to find where problem was and it is 20GB in the hidden files under the user directory can i resolve this ?

    I have a 2nd Gen MAc book Air with Lion .  The 60GB hard disc has quickly filled up despite me keeping most of my data on a portable hard drive .  I used disk inspector to locate the problem but found that it was was in 20 GB of hidden files in my user directory .  Is this correct and is there anything i can do about it ? Using disk inspector you can not see individual hudden diretories or files. I did unhide them but there is a mass of diretories etc and so no way i could see if this is one or multiple files using the space. Library System and  Applications are at 4 3 and 3 GB respectvely.  The data I actually keep on there is 9GB    Thanks for any help

    I think the problem is Quick Time Player. I am using OS 10.6.8 by the way.
    I tried it out again.
    I had about 26 GB of space before I played an .avi video.
    After the movie started to play (it was slow to load), I got a warning message that my startup disk was full. I opened Disk Utility and it told me I had no space left (about 20 MB or something like that was left).
    I watched to the end of the movie.
    Then I quit Quicktime Player.
    And I shut down the computer.
    I turned on the computer and checked Disk Utility. I have about 26 GB of space.
    I think for some reason Quicktime Player uses up a lot of the disk space when it runs movies that are problematic. This movie I was watching did not open with vlc.
    I normally use vlc to watch movies.
    Probably it doesn't use up this much space when the movie is OK.
    I think there's a problem with this particular movie. It is about 50 MB so it's not that big a file. I watch .smi subtitles with it. The Quicktime Player automatically loads the subtitle file in this case because the subtitle file has the same name as the movie file.
    I watched about 10 movie files from the same series that I downloaded together and did not have any problem watching them. I watched them on vlc. But this latest movie had problems I think (as I repeat). It did not load on vlc even though I waited for a minute, and normally movies load instantly on vlc. 
    So I think that movie file caused problems. It made QT player use up a lot of hard disk space.
    I had better avoid watching that movie in the future. I don't want it to wreck my hard drive.
    So to sum up, everything is back to normal. I have the hard disk space that I should have. However, I am scared of damaging my hard drive due to shonky movie files that eat up all the space when they are played using QT player, and so I will not watch those files in the future, as I do not know why the files do that.

  • Can anyone recommend an external storage device to supplement my mac book air?  I already have a time capsule but want the new device to replicate the data on that so ideally would like a device that i can connect to the time capsule through a cable.

    Hi CJR
    I'm not sure how Time Capsule can be replicated onto your external drive but there is a USB port on the back of TC that can be hooked up to any recent external drive.
    Another thing to think about , besides a Time Capsule failure, is the theft of your Time Capsule, so it might be a good idea to consider separating any redundant back-up from your Time Capsule or both my be stolen.
    TC will back up until full and then begin deleting the oldest back-ups.  Mine is a 2TB Time capsule.
    My back-up plan is as follows:
    1.  Macbook Air back-up on Time Capsule though Time Machine backs up everything - I think it's about every 30 min or so.
    2.  Contacts, reminders, appointments, notes, email are backed up through iCloud.
    3.  iTunes and non-itunes purchased music is on iMatch (and no need to back-up) and any non-iTunes music is backed up on an HP external drive (in case Time Capsule dies)
    4.  Photos are on my MacBook Air and are backed up on my HP external drive.
    5.  Office documents (Excel, Powerpoint, Access etc) are stored in a Skydrive app (like iCloud) and Skydrive syncs these docuemnts with the MS  cloud and my old PC and does not alter their native format like storing in iCloud would do.

  • Slow wifi on mac book air.. is this normal? (airdrop)

    when using airdrop to send from mac book air (11 inch mid 2011) to a mac book pro (13 inch mid 2011) the wifi airdrop transfers seem very slow. a 5 gig file took 30 minutes to airdrop. when i was at my brothers house and i sent 11 gigs to his imac (unsure which model maybe 2009 <- before thunderbolt) it took 3 hours.
    i thought maybe this was airdrops fault, so i connected this mac book air to my mac mini (mid 2010) using airdrop, it also took 30 minutes for 5 gigs.
    so i made a manual WEP adhoc connection on channel 48, it also took 30 minutes for 5 gigs. i then tried copying files from another laptop (a dell)
    and the 5 gig file copied at the full 300 mbps (or abouts) maybe 5 minutes to the macmini
    whats going on here??? is this normal for the mac book air?? do i have a bum wireless card?? i was going to ask a genius to switch out the wifi card or check the antennas but i thought i would post here to see if anyone else has problems
    when copying to the mac book pro or the imac i made sure that both computers were connected at 2.4 to different networks, to make sure that 2.4 was
    tied up, figuring the simulataneous airdrop connection would prefer 5 ghz. ive seen it sometimes airdrop on the same machines on the same network and taking longer because it was a 802.11g network.

    seems like any of the 2 computers on at 2.4 ghz (even on different networks) slows down airdrop. but havingboth computers wifi cards on but not connected to anybody, speeds up airdrop dramatically.
    sending from air to mini (air = 5 ghz wifi) mini (2.4 wifi) airdrop speed 12 gigs in 1 hour
    sending from air to mini (air = 5 ghz wifi) mini (not connected) air drop speed 12 gigs less then 30 minutes
    sending from air to mini (both at 2.4 ghz) 4 hours
    sending from air to imac (both at 2.4 ghz on two different networks ) 4 hours

  • Mac book air

    Which one is better mac book air 13 or mac book pro

    no heavy photo editing with layering etc, and nothing beyond simplex video editing, the Air is the better choice.
    "better" of course is subjective on your use of intent with same.
    Pack around campus/ school?  No question the Air, same for lots of travel. 
    The new Air was just released, its faster than a base model macbook pro 13" , also much faster 802ac wifi capable, much longer battery life.
    only one moving part, no conventional HD to crash.
    The (roughly) weight of an Ipad but the power of a full notebook.

  • Mac Book Air Upgrade??

    I have a Mac Book Air Mid 2011 can I have its 64gb hard drive upgraded??

    Hello quick question, i have a late 2010 model and i am wondering if i can upgrade the battery with the new battery that comes with the new 2011 mac book air. i have been getting 3 hrs of use on my air....
    As said above, you have the latest. But the 3 hrs of battery use (I assume the 11" model) seems very low. Reviews all show 5 hrs per spec, or close, with screen at 50% brightness. Unless you're doing something very processor or storage intensive, or have the screen at full brightness, I'd take it to an Apple Store and have them check it out.

  • My mac book air doesn't always charge

    my mac book air doesn't always charge. The charger doesn't always light up. Please advise.

    unlikely your charger is bad, rather it sounds as if your IO BOARD may be defective, perform a SMC reset and re-verify same.
    SMC reset
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
    If same contact Apple for full in shop diagnostic and possible parts replacement.

  • My mac book air (mountain OS X ) mid 2011 consuming a lots of data .....

    I think you mean that it's using network bandwidth.
    Any client on a wireless network, including clients you don't know about, could be consuming bandwidth. Networks must be protected with WPA2 security. If yours isn't, change the security setting on the access point. If it's already set that way, change the password. Make it a string of at least 8 random characters, including digits and upper- and lower-case letters. The password is saved in the keychain and you don't have to be able remember it; in fact, you shouldn't be able to remember it.
    You make these changes in AirPort Utility, if the access point is an Apple device, or in a web browser otherwise.
    If the network or the password was insecure, and bandwidth use returns to normal after securing it, you can be pretty sure the problem was caused by intruders.
    But intrusion may not be the issue. Most often BitTorrent, iCloud or some other cloud-data application is involved in cases of mysterious bandwidth use by a Mac. If you use iCloud, uncheck at least Photo Stream and Documents & Data in its preference pane and see whether there's any change. If you use third-party network backup software, disable that. If you use a torrent client, remove it.
    Otherwise, there's no easy way to monitor network usage per process using built-in tools. If you're an advanced user and you want to try, see the manual page for the nettop(1) shell command. It may or may not provide the information you're looking for.
    The third-party products Rubbernet and Little Snitch are supposed to record network usage by processes. I can't vouch for them. Both were available as free trials, the last time I checked. I suggest you uninstall either one when the question has been answered.
