Let’s get to the solution to each common problem.


macOS High Sierra is not downloading

Most people have complained of seeing the error of macOS 10.14 failures to download and macOS Mojave showing an error message of stalling installation or installation of macOS could not continue. I.e. the installation requires downloading vital content that couldn’t be downloaded at the time.


There are a few reasons you may encounter this issue. If a lot of people are trying to download the operating system at the same time, you may have this problem. If this is the problem, it makes sense to try again later and see if the download goes through. You can also check Apple’s Server live status to confirm everything is right on their end.


Also, if you don’t have enough storage space on your Mac, the macOS Mojave may not download. So make sure you have enough space. To check this, open your Apple menu and click on ‘About This Mac.’ Choose ‘Storage’ to check whether you have enough space or not. You need a minimum of 12.5GB to download macOS 10.14 but if you are upgrading from OS X Yosemite or earlier, you need at least 18.5GB of storage space.


Also, make sure your internet connection is fast and reliable.


If you still can’t download the macOS Mojave, find the partially-downloaded macOS 10.14 files and the file called ‘Install macOS 10.14’ on your hard drive. Delete these files and restart your Mac before downloading macOS Mojave again.


If you are still finding it difficult to download, open the App Store and click on ‘View My Account’ to see if you have something in ‘Unfinished downloads.’ You may be able to restart the download. You may also log out of the store to see if the download will restart.


macOS 10.14 Mojave won’t install

If you have a problem installing the macOS Mojave, make sure you read how to download and install macOS 10.14 Mojave. Make sure your Mac can run macOS Mojave. If you have one of the following, you can run it:

  • MacBook (newer or early 2015)
  • Mac mini (newer or late 2012)
  • MacBook Pro (newer or mid-2012)
  • MacBook Air (newer or mid-2012)
  • iMac Pro (2017)
  • Mac Pro (late 2013, mid-2010 and 2012 models with recommended Metal-capable GPU)

If your Mac is compatible and the macOS Mojave download is complete, but there is no prompt for the installation, search for a file named ‘Install macOS 10.14’ in your Mac’s application folder. Double-click it to start the installation.


If you can’t install it as a result of low disk space, restart your Mac and press Ctrl + R while it is booting to enter the Recover menu. Choose ‘Disk boot’ and then delete all the files you no longer need.


If you are finding it difficult to free up space, look out for hidden Time Machine files that are taking up too much space and free enough space before trying to install again.


In case your macOS Mojave encounters any error after installation, restart your system and press Command + Option + R on your keyboard while your system boosts to start the recovery over the internet. Shift + Option + Command + R may also work for you.


If the installation problem persists, follow Apple’s guide on how to create an external Mac startup disk. You can also restart your Mac in Safe Mode and then install macOS Mojave.


File thumbnails not showing on the desktop

If your file thumbnails refuse to show on your desktop after installing macOS Mojave, you can clear your icon cache starting the Mac in Safe Mode. You will then shut it down and restart it normally.


I can’t install macOS 10.14 Mojave from an external drive

We’ve read that most people are finding it difficult to install this operating system from the external hard drive. People complained that instead of installing, it fails and revert to the previous version they have on their Mac.


If you are using an external hard drive connected to your Mac via a USB-C adaptor, you should plug it directly into a Thunderbolt 3 port or use a different adaptor. You can also install High Sierra on the external drive and upgrade to macOS Mojave.


Bluetooth refused to work in macOS Mojave

If you have issues with your Bluetooth after installing Mojave, open up the Finder and select ‘Go’ in the top menu and then ‘Go to Folder and type ‘Library/Preferences.’  You will see a file named ‘’ Click the file, restart your Mac and connect the Bluetooth again.


Mac is running slow after installing macOS Mojave

If your Mac is not running smoothly after installing macOS Mojave, it might be a problem from third-party apps that are launching automatically when you start your Mac. If too many apps are loading at the same time, they can slow down your Mac, but if any of the apps are struggling to run in macOS Mojave, the Mac performance could be worse.


You can fix this issue by uninstalling the apps you are not using that are loading up each time you start your Mac.


You can also stop the apps that are causing the problem by opening the Apple menu and clicking on ‘System Preference.’ Follow that by clicking ‘Users & Groups.’ Choose ‘Login Items’ and select any app you want to stop from starting automatically when you start your Mac and click the small minus sign below the list.


You should also make sure your apps are up-to-date. So check the App Store to get your apps updated. You can also restart your Mac and if it doesn’t, you can force-quit apps that appear to be occupying a lot of space.


To force-quit, any app, click the app in the Activity Monitor list and then click the X at the left side of the toolbar and confirm to force-quit the app. Remember to delete the cache too.


Mac won’t start after the installation of macOS Mojave

If your Mac has refused to start after installing macOS 10.14 Mojave, you need to restart and hold down Command, Option, P & R, to restart the NVRAM.


Hold down the key until your Mac restarts and you hear the startup chime for the second time. When you hear the second startup chime, release the keys. Your Mac RAM will reset. While in Safe Mode, you can run the disk to see if it can fix the boot issue.


Apps not working in macOS 10.14 Mojave

This is another common problem with macOS Mojave. It is especially common if you are using older programs. If the apps that used to work normally have refused to work, check whether the apps are up-to-date.


Also, try to check the site of the software whether there is an update or any advice on how to get it to run smoothly. If your software is outdated, it may not work with macOS Mojave. If the software is outdated, you need to consider purchasing the newer version or getting alternative.


The latest macOS Mojave also favors 64-bit. So make sure your system is 64-bit. If it is not 64-bit, it makes sense to upgrade.


macOS 10.14 Mojave battery issues

if the life of your MacBook has become shorter since you installed this latest operating system, you can check the cause by opening up the Finder and clicking on Application > Utilities > Activity Monitor > Energy.


You will see a graph showing how much energy the programs you are running are taking up. If they are taking up too much space, you might like to check if there is an update to make the software run smoothly in Mojave.


Uninstalling the program and finding an alternative also makes sense. You can also stop unnecessary animations and graphical effects in macOS Mojave to prolong the battery life.
