Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Sorry for the delay. The no entry sign indicates that the Mac can't find the system files to boot the OS X. We may need to reinstall the O SX
What version of Mac OS X are you using ?
Note : Since your Mac is not booting up, I will not be able to connect to your Mac and fix it from here. So please ignore the remote support offer.
Since your apps were not working properly and you are now getting blocked sign, the best option is re installation of OSX. You can reinstall your Mac OS X. Reinstalling OS X won't delete any of your files. It will just replace the corrupted system files with new one and that should fix the problem.
Restart your Mac and immediately hold down Command and R keys at the same time for 15 seconds and this will boot your Mac to the Mac OS X Utilities screen. From there, click Reinstall Mac OS X. Then follow the instructions to reinstall your Mac OS X.
If that didn't work,then restart your Mac and immediately hold down Command, Option and R keys at the same time for 15 seconds and this will boot your Mac to installation screen. Follow the onscreen instructions to reinstall.
Please let me know if that didn't work, so we can continue troubleshooting.
"I tried to restore but during the process it couldn't locate my internal ssd". I hope the partition of OS X isn't corrupted. Did you already try to reinstall OS X ?
Yes. Then select Reinstall Mac OS X and follow the onscreen instructions to reinstall. It may take couple of hours
Reinstall may fail if the partition of the SSD is corrupted. So if reinstall doesn't work, then we have to erase the SSD to rebuild the SSD and then you can either reinstall the OS X and/or restore from Time Machine. Let me know it goes please
There are two causes for this problem. Either the partition of the SSD is corrupted or the SSD itself is failing which is very unlikely to happen. That is why you are unable to reinstall it and it is not appearing as a destination to reinstall.
You have three options in here. First is, buy Disk Warrior (powerful disk utility application)and try to repair your SSD or recover your files with it. If it is unable to fix the SSD, then it will at least help you to recover the latest files thatare readable and save them to an external drive. Get it from here : http://www.alsoft.com/diskwarrior/
Disk Warrior is costly. If you don't want to recover any files or have backup, then you don't have to buy Disk Warrior. It is not worth it if you don't have any important files/applications.Disk Warrior will not fix it if the SSD is failing.
Second is, if you have another Mac and a Thunderbolt/Firewire cable, then you can setup Target Disk Mode and this will allow you to mount the SSD of this Mac to that like an external SSD and you will be able to back up your non backed up files --> https://support.apple.com/kb/ph10725?locale=en_US
(After backing up,you can reinstall the OS X after erasing the drive.)
Third is, you can erase the SSD and try to install a fresh version of Mac OS X in it. This will erase everything from your SSD unfortunately. Boot into the Mac OS X Utilities screen just like you did before (Command and R). In there, select Disk Utility. In Disk Utility, select your SSD in left column and erase it. Then close Disk Utility and continue installation. This is the quickest solution if you don't mind losing the files in it. You can restore from Time Machine after reinstalling the OS X.
Let me know how it goes
If you have your important files backed up already, then you can try the third solution. Again, only do that if you have the important files are backed up.
I'm afraid we're dealing with a failed SSD. In Disk Utility, Select the main SSD in left column (the first in list, not Macintosh HD). Then click on Partition tab. Change the partition format to something else from Mac OS X Extended (Journaled). Click Apply button. This will partition it and try to rebuild the partition. Then change it back to Mac OS X Extended (Journaled) and click Apply again. Now, try to erase it. Does it work ?
How is it going ?
SSDs seldom fail. Not sure what happened here. We can try to force erase and partition it.
In OS X Utilities screen, click on Utilities menu at the top bar and select Terminal.
Type the following and press return
diskutil cs list
It will show some list of drives. Copy the UUID of Logical Volume Group.
Then type the following and press return
diskutil cs delete type UUID oflogicalvolume group here
Let me know once you did that.
I'm really sorry Tim. The results from Terminal confirm it is is an hardware issue. It is the SSD that has failed. All other components like logic board, processor, memory etc are fine. It also could be a loose connection inside the Mac (on the cable goes from SSD to board). Can you check that ? Also If you have another computer there, is there any way you can test this SSD on that Mac ?
If not, then you have to get the SSD replaced. All SSD comes with atleast 2 year warranty. So you can take it back and it will be replaced under warranty without any cost.
I'm really sorry I couldn't solve your problem, but this seems to be something we can't fix online. We've already tried the two available erase and repartitions methods. There is no other option we can try on this Mac.
I know you are looking for a solution, but I'm sorry. If you are not satisfied, please don't rate me bad or poor. You are rating my service to you, not the answer or outcome. If you are not satisfied, then you don't have to rate anything.
Let me know what you think
Sorry. That is indeed related to SSD. Slowness = delay in read and write speed = failing SSD (or hard drive)
I can assure you all the other components like logic board, processor etc are fine.
Blinking folder indicates that it can't find the SSD or system files to load OS X. Restart to OS X Utilities screen and try to erase it.
If it has worked for 5 months and suddenly slowed down, then you should consider getting it replaced under warranty. These kind of problems with SSD are rare and I'm afraid this one is failing.
Hi there, I am very sorry for the delay. We may not be able to recover them beecause we already erased the SSD. However if you have another Mac there, you can connect both Macs and see if the Other SSD can be recognised.
Yes, after formatting or erasing the new SSD you can do a restore from Time Machine or you can reinstall OS X first and then do time machine restore afterwards.
If you are in Disk Utility, then your don't need USB OS X drive. But you must do it from OS X Utilities screen. Restart and immediately hold down Command, Option and R key for 20 seconds to boot into OS X Utilities screen
If you are in Disk Utility, then your don't need USB OS X drive. But you must do it from OS X Utilities screen of Internet recovery. Restart and immediately hold down Command, Option and R key for 20 seconds to boot into OS X Utilities screen
Newer Macs can boot the OS X Utilities directly from Internet by holding down Command, Option and R keys without USB Bootable drive. This Internet recovery will let allow you to erase and reinstall OS X on the drive
Open Disk Utility, select the main one in left column, click Partition and select or do 2 Partitions and click Apply. Then change it back to 1 Partition again and apply again.
Can you double check if it is connected properly ? Also check its cable
You can also attempt to erase it with the Terminal commands I sent you before. If it returns no core storage found that means it can't recognize the SSD properly. So make sure the SSD is connected properly
OK let me know how it goes
Is there any way you could test this drive or another computer ?
Sometimes Partitioning or erasing from another Mac or Pc may work
Can you also attempt to erase it via Terminal?
Which model of Mac is this ?
First reset the System Management Controller of your Mac. Follow the steps below;
Shut down the computer.Plug in the MagSafe power adapter to a power source, connecting it to the Mac if not already connected.On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.Release all the keys and the power button at the same time.Press the power button to turn on the computer.
Then reset RAM and NVRAM
Shut down your MacRestart and immediately hold down Command-Option-P-R keys at the same timeHold the keys down until the computer restarts and you hear the startup sound for two or three times.Release the keys and let the Mac bootup.
Does it allow you to erase now ?
Yes. When you enter diskutil list it will show list of available drive and partiton with some details
You will see an alphanumerical characters or some kind of serial number at top of details in line Logical Volume Group. That is the SSD
The last commanddiskutil cs delete UUID of logical volume group number
Will force erase the drive and create new Partition.
IsIssues with cable run between the SSD and logic board may cause this. Is there any way you can test the SSDs on another computer ?
