I'm using Macbook Air. The memory is 120GB and when I check the storage, the computer said that there's an app which took up to 136GB. Which is impossible as I do not have any special app other than the basic apple app. I do not know what to do.... And there is also frequent plug-in failure. I am wondering if the plug-in failure is related to this 136GB app. Please help me out... Thanks a lot
MacBook Air, OS X Mavericks (10.9.3)
Try these steps:
- Shut down your Mac
- Wait until your computer turns off and after that press the Power button
- Right after you hear the startup tone, press and hold the Shift key
- Release the Shift key when you see a grey Apple sign and the progress bar below this sign
- Once you see Desktop, start a Disk Utility scan to detect and repair file system errors (don't forget to choose your main hard drive)
- Click on Verify Disc and then, if asked to fix problems, on Repair Disk
- After this, click on Verify Disk Permissions and then on Repair Disk Permissions
- After the process is finished, shut down your Mac and turn it back on after about 30 seconds
Apart from that, take a look at this Apple article and follow the instructions on Resetting NVRAM shown there:How to Reset NVRAM on your Mac - Apple Support
