Q: Problems with macOS Sierra?  This fix may help you.

Hi, everyone.

 

I wanted to post a solution I developed because of some erratic behavior I was experiencing with macOS Sierra (no sound, slow boot, sluggish performance, ...etc).  This fixed all my issues:

 

  1. After upgrading to Sierra, reboot your system and reset NVRAM and SMC
    1. Reset NVRAM - How to Reset NVRAM on your Mac - Apple Support
    2. Reset SMC - Reset the System Management Controller (SMC) on your Mac - Apple Support
  2. Boot normally
  3. Restart
  4. Boot to Recovery Mode (Command + R) - About OS X Recovery - Apple Support
    1. Launch Disk Utilty
      1. Click on your Physical Disk (should be the one above Macintosh HD)...click First Aid and allow it to Run
      2. Click on Macintosh HD...click First Aid and allow it to Run
      3. Exit Disk Utility
    2. Launch Reinstall macOS and complete the reinstall.  Be very patient.
  5. Once the reinstall process is complete:
    1. Restart
    2. Reset NVRAM again - How to Reset NVRAM on your Mac - Apple Support
    3. Reset SMC again - Reset the System Management Controller (SMC) on your Mac - Apple Support
    4. Boot normally
    5. Restart
    6. Boot to Recovery Mode again (Command + R) - About OS X Recovery - Apple Support
      1. Launch Disk Utility
        1. Click on your Physical Disk (should be the one above Macintosh HD)...click First Aid and allow it to Run
        2. Click on Macintosh HD...click First Aid and allow it to Run
        3. Exit Disk Utility
      2. Exit Recovery Mode and boot normally

 

 

Happy to help with this,

    That's why I always do a clean install. Saves me time in the long run.

    So here's my question.  If I partition my internal drive and do a clean install of Sierra on the new partition, what will I need to do next?  How exactly do things work from that point on?  And how big should the partition be?  Will l have to delete everything else? ETc., etc.

    How Big?

     

    If you have the space, make it the size of used data plus extra for room to grow. Otherwise, a 30-50Gb partition will give you enough room for a good test of Sierra.

     

    After you create the new install, you'll want to test with your most used apps. You can drag over a few files for testing. What you don't want to drag over are files in your User's Library.

     

    No, you don't have to delete anything.

     

    If you don't have a lot of free space on your drive, you can clone your drive to an external drive. Boot from the clone by setting Startup Disk as the clone. While booted from the clone you can run Disk First Aid to verify your internal drive then erase the drive. Install Sierra on the internal drive.

     

    Create a Clone backup:

     

    A clone is an exact bootable copy of your internal drive. Unlike standard copying of all files to another drive, the clone software copies hidden files along with other in-use files that are not available  when you copy over files to another drive.

    Software used to Clone: (Free to do an erase and copy. Paid version gives you smart updates and scheduled updates)

    Same for me.  I had tried all the above and it made no difference.  Stopping Trusteer Rapport immediately stopped the fans and improved battery life substantially.

    Dear BrainSel,

     

    I've recently upgraded my IOS to Sierra from El Captain.
    My problem, after system boot & login the desktop appear squeezed (kind of flickering) for a second & back to normal.

     

    I've observed this issue is because of using Scaled Resolution.
    If i set display scale to default & reboot again it works fine. Pls provide fix for this issue.

     

    Regards

    Mujib

    Thanks, but it shouldn't be this complicated.

     

    If all of us need to follow those steps just to get to a stable version of Sierra, I think it's absurd.

     

    I'm having excruciating problems just updating from El Capitan to Sierra ... subject of a separate post.

    Great idea, only how do I use my Mac in that case, since my keyboard is Apple's own BT keyboard?

    I'm sorry to report that the fix did not work for my mid-2010 13" MBP. I tried it twice (although I confess to leaving out the second First Aid step during my first attempt), and the laptop still kept dropping the Bluetooth connection. I even tried erasing the HD and reinstalling Sierra, to no avail. I've gone back to the old version. Thank you for giving us hope by sharing these detailed instructions, though!
