MacBook Pro is slow (with SSD)

Hi everyone, Suddenly my macbook pro (2012) is really slow. It has a 500GB SSD. When it boots I get a weird (bad) logo as you can see in the picture: The logo means that their are files missing from the OSX so I can't fully boot.

It reacts really slow and I see the wheel of the dead many times.

I have tried this:

- Reboot (duh xD)

- Going into system preferences and restart from there

- Going into safe made (command + S) and type /sbin/fsck -ty. I did it till it said the SSD was 'OK'

-Try to reinstall OSX sierra from recovery mode (command + R) However when it was going on for about 10 minutes it said 'Can't install OSX sierra' with no reason.

 

I was wondering, what is the best thing to do? I thought about trying recovery mode with an old 2.5" HDD and then installing OSX sierra and see if it functions properly. (To see if it's really the SSD) Any help would be appreciated!

Thanks!

Try booting into Safe mode

This will not load any 3rd party additions, it will load some more conservative Apple drivers (may cause screen flicker), and it will clear some kernel caches (a cache is saved data in a form that can speed up a program, but is totally redundant to the original source, and thus can be safely cleared).  Booting into Safe mode is just an experiment, but can often times eliminate any 3rd party interference, or a cached item out-of-sync with the world.

 

Although getting the cannot boot icon is more indicative of a file s

EtreCheck is a tool that helps Apple Support Community volunteers debug problems without any access to the troubled computers. Debugging problems can be a difficult task even when the machine is in front of you. Attempting it via a discussion forum is extremely difficult. EtreCheck is a great help that regards.

I fumbled fingered my first reply, so it is incomplete... I'm working on a better reply, I just posted this so you know.

As I was saying, getting the cannot boot icon is indicative of a file system problem.  You may want to try booting into Recover mode

<About macOS Recovery - Apple Support>

and run Disk Utility.

 

If that does not change anything (it is actually an fsck via a GUI, but they may use options you didn't try).

 

You may want to make a Genius Bar appointment at a local Apple store and have them run their diagnostics.

 

I previously asked you to run EtreCheck.  If you look at the section of EtreCheck that describes your SSD, you will see a button that says [Show SMART report].  Click on the [Show SMART report] and post the SMART report.  This is the SSD's view of the state of the SSD.  It can sometimes tell you if the SSD is healthy.

 

Historically, there have been a few internal disks that have shown errors because the internal SATA cable has become damaged.  In these cases, replacing the internal cable has cured the problems.

 

You may want to consider re-installing the existing operating system over-top of the existing install.   This will reapply operating system files that maybe became damaged.

 

Finally, do you have any kernel panics?  If you do, posting a few of the panic reports as Replies maybe useful

Kernel Panic reports: Finder -> Go -> Go to Folder -> /Library/Logs/DiagnosticReports

<https://support.apple.com/kb/ht2546>

<https://support.apple.com/en-us/HT200553>

The panic report should have "panic" in the file name.

 

Again, I'm sorry about the fumble fingers that caused me to post an incomplete reply

If you have a boot clone try booting off that to, eliminate the internal SSD as a test.

How to create a boot clone

I have swapped the SSD out to see if it's the HDD or something else. When I put it in a mac pro with the same OSX it showed the same thing and couldn't boot. So I think that it's the OS or a file that is been deleted by mistake. How do I fix this?
Thanks!!

This could be a case of a failed SATA data cable.  It has happened to others before, and having actually opened your Mac to install the SSD, is an opportunity to damage the cable.  But there have been reports of a damaged SATA cable by people that have not opened their Macs, so it did not have to be your doing.

 

You might want to make a Genius Bar appointment at your local Apple store, and have them perform a free evaluation of the hardware.

How can it be a SATA cable fault if I swapped the SSD to another Mac and try booting from there and still didn't work. The fault is in the SSD right? Or am I forgetting something?

I did not realize it was a different Mac. So unlikely the cable.

What do you advise me to do?
