Beachballs and almost unresponsive after Sierra upgrade

Just as a sample, it took 1 min to write that question title because after 2-3 keystrokes, the bechball would show up.

With the Yosemite upgrade my MacBook was ok but after El Capitan i started noticing the slowness but it was still ok. Now with Sierra upgrade, my MacBook Pro (mid-2012) has become completely unusable. A spinning beachball now shows up after just 3 key strokes, 3-5 seconds before the menu opens on right click, even watching a video now is an impossible task. How do i fix? Is there a way to find the OS X installer and go back to to an older OS version like Mavericks or Yosemite? Or any other suggestion?

This is a known issue with this series with the HD SATA cable. Apple has been replacing them for free. I would strongly recommend you visit an Apple Store or Authorized Service Center to have your system looked at.

I would wait until you get the HD SATA cable checked before doing these:

  • Your HD may need repairs. Do you have an external bootable drive? If not do you have a friend who has a Mac system which you can connect your system to using a FireWire or Thunderbolt cable in Target Mode? If you do you should be able to run Disk Utility to check your drive.
  • Often after upgrading the hard drive tend to get more fragmented. You'll want to free up as much space as you can. I strongly recommend you leave around 1/4 of the drive free before running a defragmentation program. To start off I recommend deleting out the Cache & Log files. Here's a tool that makes quick work off it: Disk Doctor. The defrag tool I use is this one: Drive Genius

I absolutely agree! If that cable is left in to long it will destroy your hard drive.

As a programmer with thirty years of Mac experience, I don't see what the slowness of an OS has to with all that is mentioned above. The cause is simply that the OS was written by idiots. Software shouldn't be slow under any circumstances. And if the software is, the engineers don't know what they are doing.

In this case it's not a software issue at all, OS or App!

Think of it this way you're in the top floor of a building and all of a sudden the building shifts from your perspective the fault is the floor you are on not whats below! Sadly, the real problem could be at any of the lower floors.

Here the issue is the stability of the HD's SATA cable as the processes running are trying to access or save data onto the drive. What is happening here is the CRC checksum of the given data block is failing so it needs to be resent. But, we are not talking about one block but thousands upon thousands of blocks all trying to be read or written. So the OS gets bogged down hence the Beachballs!

This is not a stupid programing issue at all it's a hardware failure!

Well Adriaan, you may know your software, but you are way out of your league on this issue and obviously have no idea of what you're talking about. And I've been at it longer than you have.

Must be a young whippersnapper who has not clue on how a computer even works. His loss.
