Once in a while (like 3 months or more) you should recalibrate the batter charge percentage. The reason is each time it charges it uses the previous value as basis (and it is a assumption that one was correct) so the error accumulates. So once in about 3-6 months, you should let your computer shut down because of a´batter warning. Now you did that it it ...

In Mail there is a Activity view. Turn it on and see what is happening. It looks like this All the bars should disappear with in a 1-2 minutes. Also check in the Mail preferences the setting for how frequently to check for Mail. Hope it is not set on 15 minutes but more frequently.

This has worked for me so far under Snow Leopard, I’m currently away from home and won’t be able to test this on Yostemite for quite a while: mkdir foo sudo mv NastyDir foo/NastyDir sudo ln -s foo/NastyDir . Now reboot and log in. sudo rm -rf NastyDir foo/NastyDir Reboot, log in, and find that there are no NastyDirs to be found.

Bad news, your GPU is shot. Good news- you might be eligible for a free repair by Apple.

Deliberately Removed Apple have removed the Computer slider from the Energy Saver settings. This is deliberate and, I believe, irreversible. The decision is related to Apple's introduction of improved hardware, Power Nap support, and the engineer's belief that OS X is best placed to manage the computer's power state. If you would like to see this ability ...

Go to Preferences → Network → Wi-Fi → Advanced → DNS and remove any previous DNS servers that were listed. Apple then automatically sets default ones or uses the ones provided by your network. I think the flush dscacheutil does not flush any old DNS name servers and inhibits Internet access.

You can do that by shutting down your computer, then when you turn it on press and hold command+option+R and wait a while (normally about 5 mins) Once your in Internet Recovery go to disk utility and format your drive. After you have done that go to Install OS X and follow the instructions. This will create an clean install. Once you do that shutdown the ...

Essentially it is not a light but is simply a hole covered with a piece of plastic. LED which are used as your screen backlight serve as the actual light for the apple mark, so the apple mark is not lit on when the screen is not lit on. In short, a crack in Apple mark will is not going to influence your Macbook in any way.

Ok, my advice is that u should unlink your email accounts and iCloud accounts from your MacBook Air. These unlink operation are to be done on MBA's side. Here is how I reached this conclusion: securityd handles cryptographic operations on OS X. All processes communicate with securityd through SecurityAgent. That fact that these two are not throwing error ...

I've had some success by installing XCode, then installing the associated hardware IO tools, which include the bluetooth explorer. The bluetooth explorer makes available tools..audio options, which lets you tune some settings. The settings I found useful were to increase the bitpool (which appears directly related to audio quality), and to increase the ...

You can also tune the BlueToothAudioAgent by installing the bluetooth explorer that comes with XCode, and then within that, selecting tools..audio options. This gives a few more options, which are no doubt all also able to be set via the command line. There are also tools..audio graphs that you can look at to see what's going on. I found that tuning the ...

You could get a brand new SSD disk and install OS X on it, carefully clean wipe the current one. In addition you could get EFI and SMC firmware from Apple. https://support.apple.com/en-gb/HT1557 https://support.apple.com/en-us/HT201518 The before you do anything (since the malware could creep right in again) install something like LittleSnich and block ...

I just ran into this as well. When booting from a USB disk that seemed to be bootable, it would display a "no" symbol ( e.g. ⃠ ...) after trying to boot into it and would then boot into the OS.

That will depend on what kind of analytical/measurement tools do you have? Oscilloscope, Volt meter ect...

There are two ways to send content via AirPlay from your Mac to your Apple TV when it comes out of the box. The first is the Mirroring method, found, as you mentioned, in the Menu Bar on OS X and in the Control Centre on iOS. As far as the in-app method goes, the only app that supports that is iTunes. There should be an AirPlay icon at the top of the window ...

First, boot into single user mode/verbose mode. If the problem persists, its hardware. The hardware problem can be as simple as a loose connector between keyboard and logic board. I had experience with a malfunctioning trackpad on my no-retina MBP 13'. The cause was that the connector came loose and only some lines of signals were fed into the system. I ...

To me that looks like possible hardware problem (the GPU). You can try the Safe mode to see if the problem persist. Also you can try and log in as different user. You can reset the PRAM, and run the Apple Hardware test. Last not least you can reinstall the OS. All above will test for software problems. There is one hardware test you can do and it is to ...

Let me suggest you the Macbook Pro and let me explain why. For me the most important thing developing with xcode is the screen resolution. You usually have two or more xcode panels open, so, more resolution means more space and let you be more agile and productive. Plus, if you use the simulator to test programs, you will want to have it in the same screen. ...

I find that the flexibility of being able to move around in the house makes it worth getting a laptop. Mobile freedom is really addictive once you get used to it. The only issue is that, for coding, having a ton of screen real-estate is advantageous. Obviously the iMac has the MacBook Pro beat in that regard, but you could get a cheap external display for ...

Turns out it's not a Mac thing -- it's a "feature" of the Acer monitor. In the monitor's menu, disable "Detect Video." Confused me for a bit, was glad to discover I'm not going crazy.

If you know how to bind an applescript to keyboard shortcut/trackpad gesture, this is the answer for you. The script is meant to be universal.

I had this exact same problem and found the answer I was looking for within one of the Apple communities. Simply go into iTunes store and scroll right to the very bottom.

Unfortunately, there is no shortcut to switch between fullscreen windows of the same application. You have two alternatives that are not ideal but enough: Shortcuts to switch between spaces/desktops or jump to a specific one Gestures to switch between spaces/desktops To make this workflow work well, just put your fullscreen windows side by side.

I finally found !! You need to buy dp1.2 to hdmi2.0 (4k support) active converter like below. http://www.kwshop.co.kr/detail_view2.html?Cat=11&cate=306&stockno=15594 ($30) Older macbook air support only 1.1 so you can't use 4k but by this converter (+hdmi cable) you can use QHD 2560*1440 monitor that has hdmi port.

This is not meant to be an answer, but a comment, since I don't know of a shortcut (but for some strange reason I'm not allowed to comment with less than 50 points reputation): apart from Mission Control, there also is the Dock, which when clicked repeatedly will cycle through the application's full screen spaces.

Hi I believe it's not a dying GPU because we have same issue in all our MAC's. It started after Yosemite upgrade. https://www.dropbox.com/s/n04b4tmbbggkftd/wierdvideoproblem.mp4?dl=0 It may be Little Snitch.

Somehow I got a silica gel ball stuck in my Android Samsung Note 3's audio jack port. I was able to use a small flat head screwdriver (the kind you use on eye glasses) and smash the silica ball by hitting it directly a few times. It turned into dust and I used an air blower to get rid of the particles. Works like a charm now.

Difficult to answer but: Do you see the CPU maxing out on the current computer (in the Activity monitor). As for the storage, it is something you can add later in form of supper fast Thunderbolt drive. You did not mention it, but adding RAM will take load from the CPU.

Only you can make the determination if paying the extra is worth it to you! Personally I always max out the RAM, processor and storage as I've always been able to utilize it all. I too program in several languages and run many virtual machines, sometimes three or four at the same time. IMO one can never have too much RAM, too fast a processor or too much ...

Nope. They're different sizes. Compare iFixit's guide to replacing a 15" early 2011 battery to their guide for a 2010 13": 15": 13": Both batteries are roughly proportional to their cases, and the 15" has a substantially bigger case than the 13". Additionally, they're shaped differently - see the little notch in the top left of the 15" battery, which ...

If the video is already recorded, you could just share the video folder with the other Mac. If you connect to the 17-inch MBP from your 13-inch and log in as the 17-inch MBP user, you can have access to all the users files. You can open the videos on the 13-inch MBP and play them in e.g. VLC player. Or you could share one folder only and set it to read only. ...

I have been getting tingling shocks from my Mac for a while, but only when I use the shorter cable i.e the converter is the plug itself. The problem stops when I use the extension cable. Must be design fault, with the shorter plug adapters not earthing properly.

Yes, so there will be loss of data when doing the USB and Apple conversion. So best one is to use analog. You seem confused over the process here. The analog-to-digital conversion is the important step, and it should be done as soon after the source as possible. The audio in/out port on any laptop is designed for speech over video calls, not music, and ...

Here is my 2 cents worth on that topic. Analog input (3.5mm jack) would go directly to the audio processor on your system and depending on the quality of the processor you will get some level of audio, but not the same as the audio line it self. If you use Audio to USB now you might have additional signal loss due to USB been the converter to serial data ...

You can record external audio with a breakout cable like this. But for best results, you should use a USB interface. I have this and it works great (and can be battery or USB powered).
