• Video of the MacBook Air to accuse by unplugged (current running off battery)

  Hello. I have a Macbook Air from 2012. The Macbook works perfectly fine when it is plugged, but the minute I unplug the unit, some video that I might be streaming suddenly freezes, even if sometimes the audio is not yet. Weird. The battery works, even if it runs in less than an hour. It has a cycle of 657 counter. The battery health is diagnosed as being 'good '. Anyone know why this is happening and what I can do about it?

  Thank you.

  Apparently, the MacBook Air is electric rationing of the battery through the

  all of the GPU, CPU, free wireless internet, open, applications and requirements

  Mac OS x itself; so many invisible things are underway in the background.

  Have you looked into the specifications of profile of electrical system and battery

  where the status of the battery is spelled in milli-ampere-hour charge remaining

  and expected full load capacity?

  I imagine that the battery can be replaced; also if SSD drive

  is full of stored content, the effort it takes the system to find the space

  for swap files and read/write then in the storage disk, is your MB/Air tax.

  Maybe an upgrade of the hard drive (SSD) ability is something to check

  in (if it is possible to upgrade) or just be sure to not have much stored on board.

  A replacement may be obtained from the macsales, OWC, among others.

  Also make sure that the MagSafe connectors are clean and free of debris on both sides

  the AC adapter and the DC-in Board (on the computer).

• iCloud keeps asking for password on iPad, iPhone, and Macbook Air

  I have a Mini iPad, iPhone 6 and Macbook Air, which is still invited to enter my password to iCloud.  All have BONES perfectly up-to-date.  On the iPad, I did a full erase and restore, nothing helps.  Since then, I also signed on iCloud and signed in on the iPad, I have not tried who still on other devices.  My iCloud username is an @me.com format, so I made sure that all newspapers in places (FaceTime, iTunes Store, messaging, etc., use this journal, even if I have a @icloud.com email too.)  I disabled 2 authentication and password specific to the Messages and FaceTime App.

  It seems to have something to do with email in particular.  On the Macbook Air from Apple email program, I get a message on the main window connection failed, and then the iCloud account is set offline.  I have to retype the iCloud password and/or exit and restart messaging to operate.

  Another thing pointing to the problem being with email that I have disabled all Push email for the iPad, and the password are stopped.  Then, when I try to retrieve messages manually, the prompt is displayed again.

  I'm out of ideas.  One thing I did not must give a new password, to disconnect all devices, then add them, one by one.

  Any help would be really appreciated.

• Sharing printers has stopped working for me. MacBook Air "think" printer is not connected.

  Sharing printers has stopped working for me. I have an Epson Stylus Photo R340 connected by USB to my Mac Mini end of 2012, and until recently, my MacBook Air has been able to print to it. Now, he 'thinks' the printer is not connected. Computers are on WiFi. Both computers have an OS X 10.11.5 now and the latest driver of Epson printer. Printer sharing is enabled in preferences, sharing, and "Share this printer on the network" is checked in the preferences, printers and Scanners. I went through the hoops to remove the printer and add it again on the Mini and the MacBook Air.

  Of course, the Mini prints very well via USB. Someone has an idea (that I have not already tried) how to get the sharing of printers to work again?

  Other sharing services work, such as the file and screen sharing?

• MacBook air trackpad crazy acting

  Hi all

  the trackpad on my macbook air has been acting and acting very erratically, starting a couple of weeks and only gradually getting worse/more irritating. There are periods where it works completely fine, but less so. Basically, even with light touches and not a double-click, the trackpad selects as he wants, clicks and double-clicks on even with light movements and clicks when I'm not touch in a way that he should take this action. I reset the laptop, I fixed the disc and I am at a loss for what could be wrong. the keyboard works fine, everything works fine. It was not any spill or weird damage to material which could explain this. I checked the settings of the mouse and trackpad and everything I had put in place to be. It's become really difficult to use the mouse without undesired shutdown of windows, select and then delete text, etc.

  I use a macbook air from 2012 and yosemite 10.10.1

  are there troubleshooting tasks or resets system I can try to help with this? all solutions? I thought I could just buy a mouse external bluetooth or something and just disable the use of the trackpad completely, but I wanted to see if there could be something else to do before that.

  Thank you!

  Try the reset SMC

  Reset the management system (SCM) controller on your Mac - Apple Support

  Also, it looks like the trackpad is triggered at all? What happened on the back side of the lower case? If the battery is expanding or goes wrong, it could put pressure on the lower part of the trackpad, causing it to act strange.

  You can check the status of your battery by clicking  > about this Mac > system report > food

  Only other thing I can think is a dirty trackpad. If you use the lotion regularly, this can make the trackpad go wobbly. Make sure it is clean.

  I was getting full boot disk error on my Macbook Air 2012 model a few times, and then it stopped starting (folder flashing with question mark began to appear). I followed the instructions on this site If flashing question mark appears when you start your Mac - Apple Support

  but failed to copy data from the drive on an external hard disk. I could see my boot (MacintoshHD) on the disc utilities drive, but could the volume seems to be not mounted.  The size of the disk is 128 GB and only 12 MB seems to be free.

  1 has started the macbook in recovery mode. In disk utility, run check disk and repair utilities disk for the startup disk (MacintoshHD). No problems in the generated logs. The volume is not mounted and is dimmed.

  2 selected MacintoshHD and tried to unlock it. The system tried for a while, and the password window disappeared after some time with the MacintoshHD via disk utility.  When I restart the machine again in recovery, disk MacintoshHD reappears in the same situation.

  3. I was able to start the macbook after installing a new version of OS X in an external hard drive. During the installation of OS X, I couldn't copy the data from the volume MacintoshHD (possibly the drive is locked).

  4. I could not start my macbook in safe mode.

  My query is-

  1. I had not backed up my data by any means. What are my current options to copy my data MacintoshHD?

  2. because the MacintoshHD is locked and attempts to unlock it had no disk utility, it will help if I start my macbook target disk mode, connect to another mac via a thunderbolt cable and try to copy data?

  3. What are my options now to restore my macbook? Clear my boot drive (MacintoshHD) and reinstall OS X?

  Thank you
