There is no perfection in life, no matter how hard we try to get there. That doesn't mean we should quit. Instead, we should try harder and harder. The same premise applies for operating systems. No operating system is perfect and flawless. Apple's macOS Sierra is another example of a great operating system, but with few flaws and problems that might occur. macOS Sierra comes with a number of improvements to security, benefits, practical features, and much more. This time, however, we would like to emphasize some of the problems that might occur, and the solutions for both macOS Sierra and High Sierra.

Solutions to Common macOS Sierra Problems

1. Sierra is Frozen/Stuck

Some users have already reported challenges for installing the new operating systems. The setback happens at the very first step, as their installation freezes after 30 minutes of installation on MacBook, or at the 90% point on Fuji. Here are some useful tips how you can fix the freezing problem:

2. Can't Start Mac after Update

Some users get stuck at the first step, others get stuck at the second step. In any case, it is a problem that has to be eliminated so your computer can run smoothly on the new operating system. After you've installed macOS Sierra, your computer cannot boot up, and all you see is a white screen, and an Apple logo on it. Here is how to fix the problem:

  • Restart your computer, and then hold down: Command, Option, P and R. This will reset the NVRAM and should fix the issue
  • Reset your system management controller to fix the problem. To do that, shut down your Mac computer, and then unplug all cables from your Mac. After several minutes, plug the cables back, and start up your computer
  • Booting Mac in safe mode can help as well. But you have to make sure that you have at least 9 GB of free space on your hard drive

3. iTunes Doesn't Respond

Truth be told, iTunes is often an issue with Mac operating systems, as the applications has a complicated sync operation. No matter the case, if the latest version of iTunes, which is 12.5 does not respond to Sierra. Here is how to fix the problem:

  • Try the simple route, which is restarting your Mac computer
  • Safe mode can help again, and you need to start iTunes while in Safe Mode, and go to troubleshooting to solve the error
  • Turn your WiFi off, and then go to iTunes menu. From there, go to Store and Sign Out. Now, turn the WiFi back on, and open iTunes
  • Reinstall your iTunes application.

4. Sierra Working Slow

When you install a new update, you expect your computer to run faster and better. Some users have reported that after the update, their Mac computer is working slower. It can be annoying and irritating to have a computer working slower when updating from one operating system to a newer. Sierra has been reported to work slowly in Safari, iTunes, Word and Preview. Some solutions to speeding up your computer include the following:

  • Delete the file log manually which can be located in the folder by pressing "Command + Shirt + G". The file is located: ~/Library/Containers/
  • Use Disk Utility to repair your disk permissions
  • Run PRAM and SMC resets on your computer

5. Apps Are Damaged

Your new macOS Sierra should upgrade and make all applications compatible with the new operating system. However, users have reported that they are getting "damaged application and can't be opened" messages when trying to run some of their favorite applications. Some of the apps include mail and photo apps. Here are the solutions for the problem:

apps are damaged
  • Empty all caches
  • Remove plugins. For your Mail application, plugins are installed in /Library/Mail/Bundles and ~/Library/Mail/Bundles
  • Reset PRAM at startup
  • Try to check "allow applications downloaded from Anywhere". This setting is located in Security and Privacy, under the field "System Preferences".
  • When you are launching the app, hold down "command + option".
