5. High Sierra Password Security Problem

macOS 10.13 problems password

Though the 10.13 version rolls out with plenty of nice security upgrades, including invasive ad tracker blocking in Safari and weekly firmware validation, many users reported that the new OS apparently comes with a security problem, too - It's available to snatch passwords from High Sierra. That's to say, if users opt into using Keychain, they can extract plaintext passwords from the Keychain where stored their login information, credit cards, and WiFi passwords etc. Some users stated that they'd avoid updating to High Sierra until the issue was fixed. But Wardle, the discover of this High Sierra error, thinks everyone should update since there's a lot of good built-in security features and this attack works on older versions of Mac OS as well.

Nevertheless, to keep your Mac safer, users should against installing unsigned apps, download software only from trusted sources like the Mac App Store, and pay careful attention to security dialogs that macOS presents.

6. iTunes Not Working

Also as you upgrade to macOS 10.13 and launch it , you may get stuck in iTunes. You find that your iTunes is not available on the latest operating system.

It's an MS-DOS formatted little slice that's needed when updating the computer firmware. If the update fails, the installer won't proceed.

10. App Incompatibility: Apps Are Damaged or Cannot Be Opened

problems with macOS 10.13 apps

As we know, every time upgrading to a new Mac operating system, there are some apps incompatible with the new Mac OS. 10.13 is no exception. You will find some Apps show "damaged and not be opened" error. For example, apps like Final Cut Pro X 10.3.4, Motion 5.3.2, Compressor 4.3.2, Microsoft Office 15.34 or earlier, Dropbox etc. won't work on High Sierra. For this macOS 10.13 problem troubleshooting, there are two ways: clear caches or update the damaged Apps like DVD ripper for Mac to the latest macOS 10.13accepted version.

11. Video Problems

After successfully updated to macOS 10.13, users will still have issues on video playback. The video playback problems can be originated from both in system error and video formats issue. Generally, if you find that your Mac's display starts randomly showing rainbow colors when turned on, especially when it comes to display drop shadows in the system UI, then you need to perform a SMC reset. Take Macbook as an example to reset SMC for macOS High Sierra problems troubleshooting.
1. Shut down the device
2. Plug in the power adapter
3. Hold down Shift + Control + Option on the keyboard, as well as the Power button at the same time.
4. Release the keys and the light on the power adapter will change color briefly.
5. Boot your MacBook normally.

On the other hand, formats issue may also cause video playback problems. For example, certain formats like mkv, flv, mts, wmv, avi etc., are not acceptable for QuickTime on Mac computers. To fix this macOS 10.13 problem, you can fall back on a video converter like MacX Video Converter Pro, which solves videos not playing on macOS 10.13 problems by converting among almost all the 4K/HD/SD video formats without losing quality.

12. Safari Crashes

macOS 10.13 Safari crashes

Safari being the essential searching browser on Mac, you cannot imagine how terrible when it's not working. But unfortunately it does happen to macOS High Sierra update. Usually the macOS 10.13 problems about Safari come with the situations that Safari can't find server, unable to load webpage, links don't work, can't render CSS etc. As for this macOS 10.13 problem troubleshooting, try to exit and reload Safari to find whether it works. If not reboot your Mac computer and try to launch Safari again.

Actually, updates to Safari hit the Mac earlier as separate downloads. On the other hand, some capabilities of Safari 11 do require High Sierra, however, most notably accelerated streaming HEVC video playback. But there isn't a lot of that content available yet to stream. So if you want Safafi 11, you don't need HIgh Sierra.

13. macOS High Sierra Drops Pinter Connection Error

Generally, if you're having trouble on printing, the first thing need to do is to check your printer connection. Likewise, you find your printer connection is dropping after upgrading from Sierra. So you can try to delete the printer in System Preferences and add it back to check whether it works.

14. iMessage Delays

Some macOS High Sierra users are reporting delays in receiving iMessages on their Macs, while also finding that they are no longer receiving iMessage notifications on their iOS devices and Apple Watches. The High Sierra bug may be related to Apple's plans to offer iCloud sync of messages later this year.

And according to Apple Insider, those who are experiencing the delay are reporting anything from minutes to hours. Users report mixed success with a range of measures, such as signing out of iCloud on the Mac, but downgrading to Sierra is the only thing that seems to work for all.

15. The WiFi Is Slow or Dropping

If you encounter a slow or dropping WiFi after upgraded to macOS High Sierra, you need to delete your current WiFi preferences firstly. Reboot your Macbook Pro or Macbook Air afterwards, as well as your modem or router. If you don't know where to delete Wi-Fi preferences, you can find it in the following folders using the Go to Folder command (Command+Shift+G):

  • com.apple.airport.preferences.plist
  • com.apple.network.identification.plist
  • com.apple.wifi.message-tracer.plist
  • NetworkInterfaces.plist
  • preferences.plist

16. Mac Overheats

Mac overheats

Another problem about macOS 10.13 update is the Mac computer overheats and fans keep spinning, making their machine a lot noisier to use. The cause of fans constantly spinning is if the Mac reaches a certain temperature. The fans kick in to help lower the temperature after you installed macOS 10.13. Actually, the fans cannot cool the Mac sometimes even if they spinning constantly. To fix the Mac overheat problem, you can cool down Mac by stopping Finder from indexing your hard drive or powering off the Mac for a while.

17. External USB Hard Drive/Devices Cannot Be Recognized

"Hi guys so I have 2 Seagate hard drives that works perfectly well, but when I upgraded my Mac to macOS 10.13, it just suddenly won't read it. My Mac is MacBook 2015." - Apple Support Forum

I found many Mac users have encountered the same puzzles. For this macOS 10.13 update issue of USB devices not being recognized, you can reset the System Management Controller (SMC) on your Mac. Whereas, if the SMC reset didn't solve the issue it may help to reinstall the macOS 10.13 update using recovery mode by restarting your computer and holding down Command+R until the Apple logo appears on screen.

18. macOS High Sierra Keeps Logging You Out

Some people have been reporting a problem where macOS High Sierra keeps randomly logging them out of their Mac. It's annoying, but the good news is there's a number of fixes for this High Sierra problem.

First of all, go to Preferences > Security & Privacy > Advanced, and uncheck the box where it says 'Log out after… minutes of inactivity'. In the Security & Privacy window, click 'General' and uncheck the box 'Require password after sleep or screen saver begins'. Remember the security implications of this, however.

On the other hand, if High Sierra is logging you out while you’re using Chrome, try opening up the Chrome web browser and going to the settings. At the bottom of the screen click ‘Advanced’, then turn off hardware acceleration.

19. Bluetooth Problem

So far there is no widespread macOS High Sierra Bluetooth not connecting problem. But if you have encountered the Bluetooth not connecting issue, you can try unpairing the device and reconnecting it to your Mac. Simply click on the Bluetooth icon in upper right area of your screen then on open Bluetooth preferences. Then Hover over the device and disconnect it from your Mac by clicking on the X. From there, you can re-pair it and see if that works for you.

20. No Mail Notifications

There are also some people reported that after they upgrade to High Sierra, they are no longer noticed with notifications when recieving mails. To get this problem solved, you can go to System Preferences > Notifications and changing the alert style from 'Banner' to 'Alert' or 'None'. Then change it back to 'Banner' and banner notifications should now work again.

Of course, it's also possible that the steps do not help, you can reboot your Mac with Safte Mode (Hold sown the Shift key when your Mac is starting up to enter safe mode). Then try to send a test mail to yourself to check whether the notifications work. If they do, restart into normal mode and try sending a test email again.
