You cannot erase the currently-running volume. Shut the computer down, restart while holding the option key, and choose the Recovery HD. Find Disk Utility in the menus and you will now be able to erase your internal storage.

I'm somewhat convinced this is a software issue, and not a hardware issue. I have exactly this problem too. The reason I say "software" is that so many people are experiencing the same symptoms, whereas water damage may affect other keys, not specifically shutdown. I have a macbook air that I almost never update, because I have a stable system and use it ...

Sure you can. On System Preferences → Users & Groups under Login Options you have Automatic login where you can chose an user. When you select an user there, It will automatically login when you switch your Mac.

You need to disable FileVault and then it would allow automatic login. But be aware thats not good for your information protection.. your mac would be vulnerable..

What worked for me: open up a Terminal window and: sudo killall coreaudiod

Your display is made up of pixels which are each made up of 3 subpixels, red, green, and blue. (This is the LCD part in the picture below.) Unfortunately, since red is on the left, it may look a little off center. Here's a screenshot of the button: and here's what it looks like on my display: It would have been difficult for Apple to avoid this ...

Thanks! My problem was slightly different: Double-tap to open a file/folder using the trackpad on my laptop no longer worked after I upgraded to Yosemite and after checking the "dragging" option, it started to work again! No idea why but I'm just glad it's fixed. Thanks!!

Your computer is currently set to mount and show hidden partitions, which is unusual. To get control of this feature, you need to activate the Debug menu in Disk Utility which then gives you the option of viewing and mounting hidden partitions, or indeed, making them hidden again. Try reading this article which gives instructions: ...

Or is it massively more difficult to solder new memory into a laptop than it is to solder some simple electronics project? Yes, it is; although "massively more difficult" is almost an understatement. It's an entirely different process. Take a close look at the Macbook Air motherboard. The RAM chips are the four large components in the red box on the ...

iFixit, who is a proponent of replacing everything in your system, does not provide a guide to replace the RAM (only the entire logic board, on which the RAM is soldered). This alone should tell you that it is something that should not be attempted by users who are not professionals. One user did ask in their forums if it was possible. Here's one response: ...

It's most likely because the difficulty (practical impossibility?) of getting RAM that is compatible and would fit inside the case. They don't use SO-DIMMs.

Rebooting to upgrade to 10.10.1 seems to have fixed the problem for now.

I have had this happen a few times myself. If I was to guess, at the time you closed you lid on your computer you had the power supply hookup and running. After the lid was closed you removed the power plug. Later you open the lid, without the power plug and it was a blank screen. If this is your case, you have two options, unplug first before closing ...

i use a diamond USB adapter to work around that.. the refresh on both screens is a little slugish, but if you stay away from mission control and other graphic consuming resources, you should be able to get through the day with 2 monitors :) http://www.diamondmm.com/bvu195-diamond-external-video-display-adapter.html

Apple released the 10.10.1 update today, which is supposed to fix many wifi issues.

To better understand what is it doing during the sleep and what is consuming your battery: Your system is set to absolute sleep (no activity at all) for 4200 seconds (that is standard) You have the "womp - wake on ethernet magic packet" enabled. Unless you need that, you can disable it with sudo pmset womp 0 You can look up the reason for wake by using ...

Plug in your power adapter and turn the machine off. Press and hold control+option+shift+power buttons for 5 seconds. This resets the System Management controller, which is in charge of power flow through your machine and also things like the speed of your fan. http://support.apple.com/en-us/HT3964 If that does not help, the computer may still be damaged. ...

sounds like you only recovered the low-quality proxies. The structure should be Project Name folder, containing CurrentVersion.imovieevent file & Profect Name.rcproject folder, containing Movies folder Project file Proxies folder QuickLook That applies whether you have the old iMovie structure or the new one. If you have the new structure that ...

I had what sounds like the same problem and somehow either updating to the latest software (yosemite as of now) and/or opening up dictation and speech has fixed it for now. I have no idea why. But if anyone else has this problem you might as well try it if you haven't already. I was on skype with a friend, hung up, went to go do something else without ...

Unfortunately I think only Apple can fix this, hopefully with an update to Yosemite (which is reportedly already being tested, but a release date is unknown). Until then, all I can offer is a workaround. Find Your WiFi "port" First you need to find your Wi-Fi port. On a MacBook Air this is probably en0. On a Mac with built-in Ethernet and Wi-Fi, the ...

Venicejeff is right. To expand, you can't daisychain monitors that don't have a thunderbolt port on them. DVI and VGA require dedicated inputs. So if you want those two monitors you will need an adapter that gives you another video port. Like a thunderbolt dock and some adapters or that Matrox unit that you mentioned in your question. The only other option ...

since they air only has 1 thunderbolt and some usb2 ports, you're pretty pinched. you could get a thunderbolt dock along the lines of the caldigit unit.. this has an hdmi and a pass-through thunderbolt on it. you can then get an hdmi-dvi cable for oen monitor and a thunderbolt to dvi adapter for the other. another option would just be a thunderbolt hub. ...

Mine was doing the exact same thing after water damage recently. I was worried it was the logic board but I replaced the keyboard today for $30 and it stopped prompting to restart! Was much cheaper to fix than replacing the logic board. I guess it must have been some corrosion with the power button.

Go to system preferences, keyboard, input sources and check the box to show input sources in the menu bar. Then via the menubar you can open a keyboard-viewer. Now hold your fn key and press f10. If it doesn't light up on the virtual keyboard it's probably the key itself. If not, you'll have to check what interferes, maybe some sort of shortcut-software ...

Mountain has a feature called "Remount USB storages" to do what you want. This blog article tells you how to use Mountain to solve common issues with the Nifty MiniDrive like battery drain in sleep mode or how reattach the SD card after it has been ejected. Best thing is Mountain installs a priviliged helper tool, so you don't have to enter your ...

This is not an answer but perhaps a hint. I am (since Yosemite) having this problem with all the Office for Mac programs. If I "open recent" no problem. If I open from Finder instead of the application, no problem. But if I open Word or Excel or Powerpoint and then go to find a file, the program becomes unresponsive and I have to force quit.

I attempted to upgrade my late 2010 MacBook air with an SSD from OWC. The first one worked for 3-4 hours and then the system wouldn't recognize it. I RMA'd it. The system wouldn't even recognize the replacement. The original SSD continues to work fine.

What you're encountering is not related to the pre-existing version, but likely that your MacBook Air is not supported for Yosemite at all. Apple lists the Late 2008 model as the earliest MacBook Air which can run Yosemite. (Source) http://support.apple.com/en-us/HT6412

I think the best option would be to create a bootable USB drive and install from there. But if you need to do it via a local file, I would copy the Upgrader File to the /Applications folder of the MB Air. Yes, you should make a backup. Especially since you are jumping a couple versions of the OS. (In truth, I have not had a problem with any of the 30 or ...

According to this Apple support article: Set your mac to log out when not in use - installing Yosemite turns on the "log off after 60 minutes of inactivity" feature. To turn it back off, click on the "Advanced" button at the bottom of the "Security and Privacy" window and uncheck the option. You should be good to go!

I ran into some issues like this with a PDF which contained some embedded vector images… the images were plots generated by Mathematica which had been exported as PDF files. The images were composed of a few thousand data points. As Preview attempted to plot these (thousands of) vectors, it would lock up (just as you describe). Exporting the images from ...

You could, but how would you know which is correct? You would need accurate profiles for both screens. This could be done with colorimeter hardware/software, something like ColorMunki (No affiliation, it's just what I use myself), which can calibrate both your Mac & iPad screens [also PCs, if you have them] An app like Photoshop [& possibly Gimp, ...

I have a MacBook Pro 13" 2012 and a MacBook Air 13" 2014, and the MBP has longer key travel distance when you press it. Not much, but noticeable. I also think the MBP 2012 keys are more "hollow", formed after the finger tips, whereas the MBA keys are flat.

Spotlight is re-indexing after the upgrade, which means it's busy all the time, impacting performance and battery life. Never try to judge the performance or battery impact of any major OS X upgrade until the machine has been turned on but idle for at least a week, to give time for the re-indexing to complete.
