Can somebody PLEASE help me :s I know nothing of technology and I, as a student, don't have the money to buy a new laptop or to go the official apple repair service...

It seems the OS is Mavericks, OS 10.9.5. Also, it looks like you have the same MacBook Air model I have.

Have you ever done any disk cleanup/maintenance/repairs?

Are you making any backups to an external device?

We have a Time capsule that takes backups...

Never done a disk cleanup or something like that :s

 

[honestone]

OK, at least you have a backup. That is to an external device, right? And, by Time Capsule, you mean Time Machine? (I use something else for my backups, so that is why I ask). How often does Time Machine run?

Now, you should first try and do some disk cleanup/maintenance/repairs. First, on your own, get rid of ANY stuff you do not need. That would include any prior versions of software.

Secondly, download, install, and run the excellent freeware program Onyx. You can get it from here:

http://www.titanium.free.fr/onyx.html

Note that there are specific versions for each Mac OS. Since (apparently, and you need to confirm that) you are using Mavericks (OS 10.9.5), you would download Version 2.6.8. After you install it, start it up. You will first need to enter your admin password. The, let it check the structure of your disk. When that completes, start with the Maintenance tab. Within that one, there are 3 tasks you need to run:

Permissions
Scripts
Rebuilding

For Permissions, run it multiple times. You should see the list of permissions repaired getting smaller and smaller. For Scripts, check off Daily, Weekly, and Monthly.

Next, after completing Rebuilding, click on the Cleaning Tab, and run each of those sub-tasks (I believe that version does not have Erasing as one of those tasks. If it does, DO NOT run it).

When you run some of those tasks, the software will tell you that you need to Restart your Mac. That's normal, so just click on Restart when you see that screen.

The main things Onyx is going to do are Repair Permissions, and clean out some unneeded stuff. You should get into the habit of running Onyx periodically. Myself, I do it once a week, as part of my weekly disk cleanup/maintenance/repair, and backup, processing for each of my Macs. I also am doing cleanup every day on each of my machines, by permanently removing stuff, including EMails I no longer need.

Next, launch Disk Utility. It is contained within the Utilities folder, which is within the Applications folder. I can't remember if you can Repair the disk at that time, but instead need to launch it "externally" (I have a couple of more robust third party apps that can do repairs (along with other tasks), so I don't use it for that purpose).

Report back after you have done all this. One other thing you need to check, just in case you need it: Click on the black Apple icon in the upper left hand corner, then select About This Mac. On the screen that appears, click on System Report. Then, click on SATA/SATA Express. It will then show your internal SSD drive, along with the partitions on it. Hopefully, one of them is "Recovery HD". Let us know if you see it.

 

[Steven-F]

Thank you for trying to help me...

I did every thing you asked (multiple times).... But still... the problem keeps happening.
I have a Revovery HD:

Recovery HD:

Capacity: 650 MB (650.002.432 bytes)

BSD Name: disk0s3

Content: Apple_Boot

Volume UUID: 016CFB00-41A9-336E-B68D-C059D6C1A61E

 

[honestone]

Sorry for all your troubles. I am not very good at reading (and understanding) the info you posted above, in your first post. Maybe someone else with more intimate knowledge can provide guidance. Short of that, you might need to do a complete re-installation of OS 10.9.5, along with recovering all the other needed "stuff" from your backup. But, that is a somewhat detailed process, and if you pursue it, we can give you instructions here. It is, though. somewhat "risky".
