MBP extremely slow after SSD Upgrade. What's wrong with my mac?

I have a MPB 15" 2.53 mid 2009. I upgraded the standard hard drive to a SSD (512 GB Sandisk X210) purchased from ifixit.

I cloned the factory drive to the SSD using Super Duper. After cloning the HDD to the SSD I installed it and turned it on, it booted up fine but not quite as quickly as I would expect for an SSD.

Verified and reparied disk permissions.

Restert. Boot up time about 1 minute 20 seconds.

Shut down.

Reset PRAM

Boot up about 1 minute.

Restart. Boot up time about 43 minutes.

I have no idea what happened in the middle there but something is obviously not working right. Now when I click on applications they go gray then take several minutes before launching. I'm not sure what to do. Please help!

I would start by making sure your systems firmware is upto date. Follow this Apple TN on how check & update EFI & SMC firmware updates for Intel-based Macs.

Remember your systems SATA I/O speed is only SATA II (3.0 Gb/s) make sure your SSD can run at that speed.

See if putting back your your old HD back in if your system still reacts the same. If not, try running your SSD externally via a FireWire (best) or USB connection. If it runs better there you may need to replace the SATA cable.

How do I check if the ssd can run at these speeds?

My bet is on the cable , of course, a pet peeve of mine. MacBook Pro 15" Unibody (Mid 2009) Hard Drive Cable

To check what your SSD can do review the specs sheet that came with the SSD, or visit the vendors web site to get it. I also recommend you check both the systems & SSD firmware to make sure its up to date. Often I find that fixes things!

The internet had the answer for me. Apparently your startup disk setting is pointing to a disk that's no longer in your system. I'm guessing the OS can't find it and is waiting for it to spin up. It doesn't try the new SSD until a timeout occurs.

Go to system preferences and set your Startup Disk setting to be the new disk and I'll bet that changes everything. It did for me.

Good catch!!

It also works for me. I had before for the long time just the white screen before apple logo comes on.

It worked perfectly!

I had the same problem when I upgraded my original 128GB SSD with one of 256GB from Transcend. I couldn't understand why the new SSD had added 10s of grey screen on startup before the Apple logo appears.

So I follow these steps and all started working perfectly again:

1. Go to System Preferences -> Startup Disk

2. Click on the bottom left Lock tu unlock the changes

3. Select Macintosh HD (it's likely to be the only on the list)

4. Click 'Restart...'

You're done!

Thank you so much! Its working!!

Solved!! - I had almost exactly the same symptoms. SSD upgrade Super fast for a month, then suddenly became slower than ever. Symptoms included unable to keep up with keystrokes (really annoying), slow application loads, slow printing.

I tried just about everything suggested on the internet; Reset PRAM, SMC, the wear levelling (TRIM). Reinstalled a clean OS (Lion, Yosemite, and El Capitan). Nothing made the slightest difference. I bought a different drive (i had a samsung EVO) I read the OWC were great...no change.

Then one day the mac failed to find my hard drive. I was pretty ticked off by now. So my research for this problem went down a different road. And I ended up buying a replacement SATA cable MacBook Pro 15" Unibody (Mid 2009-Late 2011) Hard Drive Cable Fixed it completely - Mystery solved.

So if this post helps just one person avoid six months of torture I will be delighted.

Man, you've just saved my brain. I was suffering of the same issue during the last month. I've tried almost everything you've tried, but only cable replacement helped.

I had the same problem. Replaced 3(!!!) SATA cables. No joy at all. Ended up with installing back an old good HDD. My old MacBook Pro 13" Late 2011, works fine again.

door

@ Rob Fox-- so installing the new SATA cable was only a temporary fix? I'm assuming that's why you went through three of them? Also, what type off SSD were you using?

HELP!

I have quite a similar problem. I upgraded my MBP 13" mid 2012 with a Samsung 250gb 860 EVO 2.5" SSD. I've done tons of research before I proceeded changing my MBP drive with an SSD. However, my macbook is acting wierd with the SSD but not with the HDD.

my problem is:

- when I turn on my macbook, halfway through the bootup loading screen it shows a "Prohibitory sign" ( which means a valid start-up disk has not yet been found), after a few minutes the screen shuts off then turns on and displays the loading screen and continues to complete the bootup. After the bootup is complete it takes few minutes to load up the mac OS interface and Once I'm on the mac OS interface everything is so slow and sluggish, whenever I moved my mouse or even open a folder or anything my cursor keeps on turning into a colorful spinning wheel.

I have tried:

- tried cloning the factory drive to the SSD using Carbon Copy and I have reset PRAM..

- tried installing a fresh copy of Mac OS from a USB stick and external hard drive.

-tried creating an external bootable drive by installing the Mac OS on the SSD using SATA to USB cable

-tried system preferences and set Startup Disk setting to be SSD

Note:

The SSD is working fine, I tried it on my sisters MBP 13" mid 2012 and it was working perfectly fine.

I also, tried booting up my mac with the external bootable SSD drive using SATA to USB cable and it works perfectly fine. However, when I install the SSD on the mac the problem occurs again. So, I was thinking it could be the sata cable. Next, I tried using a different hard drive and also tested my sisters MBP hard drive on my mac and it boot up just fine.

My findings was that my MBP doesn't like the SSD but works well with any other HDD.

I have not tried using a different SSD,

I have not tried changing the sata cable yet.

What could be the problem?

and tried all possible way I could think off. I tried the

Were you able to resolve this issue? I have the same problem and after tons of research, many say the issue is a faulty SATA cable. I'm currently waiting on the cable to be delivered from Amazon.

boot the Mac Holding Command + S, once the commands have stopped popping up on the screen and you can type, type the following thats in quotes but don't include the quotes "fsck -fy" note you may have to run this command more then once, I had to run it 3 times before the output command said that it mounted the drive correctly, it also sped up my SSD

the hard drive name has nothing to do with it. You can name it whatever you want as long as you select it in the system preferences control panel as the startup disk.

How do you set it to the new SSD? It still only has the Mac HD listed.

Press the Option key when you start you system. You'll be greeted with the Disk Manager which will allow you to select the boot disk. Once you system is up and running go over to your System Preferences, there you'll find the Startup Disk control panel, open it and select the drive and you're done. If you can't see the disk its not prepped correctly and/or is missing the OS. You'll need to redo the drive setup and re-install the OS from the installer app.

It's also worth noting that if you clone the old hard disk onto the SSD, you'll retain the name "Macintosh HD" for the SSD. This is not sufficient to automatically boot from the SSD. (Somebody correct me if I'm wrong, but the boot loader works with physical disk IDs, and not the name, since it has to boot before the file system is loaded.) You'll need to set the boot disk to "Macintosh HD" once again to register the new disk.

Good point! @EBarnhart001 Another reason not to use cloning software as it just confuses things.

I know old habits are hard to shake, cloning is one of them! I have had more problems with cloning software than I can shake a stick at. Apples Migration Assistant or TimeMachine backup is the only real way to do it.

door

I don't remember if I cloned or restored the system disk image from a backup onto the SSD. Probably the latter since I used no special software. Anything that saves the hassle of reinstalling the system is a good idea IMO. The user just needs to unset and reset the startup disk setting, even if it looks correct in the control panel.

door

@EBarnhart001 not true. It doesn't have to be called Macintosh HD at all. That's simply the name Apple gives it by default. I rename all my HD and SSD to MacOS HD and it won't affect a thing. All apps will see it etc. The name can literally be anything. He'll you could name it floppy disk for all the Mac is cares. Just be sure it's set to the default startup disk in system prefs and it'll boot fine. This issue 8s definitely the sata cable. even after a successful clone you can go in and rename the same hard drive you just clone to whatever you want and the system will still boot just fine. It's all about the Sabbath bus and has nothing to do with the actual name that you give the drive. try it out, rename your hard drive and reboot your machine and it'll boot up just as fast and everything will retain its symbolic links etc you won't have a single issue
