Apple has been pouring a lot of love into macOS Mojave since its initial release. However, we still have heard some of the problems that Mac owners are facing with macOS Mojave. In reality, Apple releases new updates to its latest macOS version on a regular basis in an attempt to fix bugs and errors, but what’s the fun when you are facing problems with macOS Mojave.

To help you fix some of the common problems with macOS Mojave, we have compiled a list of all the known issues and possible fixes. Before trying to do anything, we highly recommend you update your macOS. Keep in mind that a new software update usually comes with bug fixes, so it’s a good idea to keep everything updated.

Connectivity issues

A lot of Mac owners have reported that their Macs lose network connectivity in apps like Mail and Safari. If this is the situation where you are now in, then try starting your Mac in Safe Mode.

In reality, booting your Mac in Safe mode helps to fix some major software problems. To do this, reboot your Mac, then press and hold the Shift key until the Apple logo shows up. Release the Shift key when the login window shows up.

If the problem still persists, then try removing any extension you have installed on Safari. To do this, open Safari on your Mac, then select Preferences and click Extensions. Now just simply check the boxes next to all the extensions you wish to remove.

Mail problems

There have been some reports that Apple Mail fails to work after updating to macOS Mojave. A lot of Mac owners say that the problem even persists after they reboot their Macs. If Apple Mail app crashes or slows in macOS Mojave, you can follow our steps below.

Step one: First off, force quit the Mail app using Activity Monitor and then open Finder app

Step two: Next up, hold the Option key and select Library. If your user library fails to show up, use the following keystroke: Command+Shift+Period. Doing so will reveal all your hidden files and folders in Finder.

Step three: Navigate to Containers > > Data > Library > Saved Application State, then locate the folder named and drag it to the Trash

Step four: Open the Finder app, then press down the Option key, then click Go and navigate to ~Library/Containers.

Step five: Locate the following two files: and and move them to the desktop

Step six: Remove the Mail Envelope Files from the library. To do this, open Finder, then click on Go, and hit Go To. Now just simply locate Mail folder, then remove the three envelope files within the MailData folder and empty the Trash.

Step seven: Restart your Mac and launch the Mail app to see if the problem is fixed.

Unable to Log-in to Mac in macOS Mojave

We have heard reports that Mac owners cannot log into their Mac after updating to macOS Mojave. Luckily, we have a fix for you, but we recommend you reboot your Mac first to see if the problem is dealt with.

Once your Mac boots up, hold down the Command + S keys then enter the following command: /sbin/mount -uw / and press the Enter button. After that, enter the following command: rm /var/db/.applesetupdone and press Enter. Your Mac will restart and then ask you to create an admin account.

Chrome Won’t Load Webpages in macOS Mojave

Apple’s Safari comes pre-installed on every Mac on the market, but there are still reasons to switch to a third-party web browser. Chrome is a leading web browser out there that is now available on multiple platforms. Google says that Chrome is now 50 percent faster than Safari in macOS Mojave, but there are times when it becomes a cause of annoyance.

There have been some reports that Chrome fails to load webpages in macOS Mojave. Personally, I find this pretty annoying as I could not access my favorite webpages. The best shot to deal with it is to uninstall Chrome and re-install it.

Mac Running Slow in macOS Mojave

MacOS Mojave promises a huge performance boost, but to be honest, it is not massive. Indeed, macOS Mojave is even slower than its previous version when it comes to the boot speed.

A lot of Mac owners report that their Macs are running slow after updating to macOS Mojave. The problem might be with some background processes and services. So, it’s a good idea to disable startup apps on your Mac. To do this, open System Preferences > Users & Groups > Login Items and select the apps you wish to disable at startup.

Another solution is to force quit an app that takes up the most CPU and RAM. To do this, open Activity Monitor, then locate any app that uses a lot of your Mac’s system resources and shut it down.

iCloud not Syncing Properly

One of the most annoying problems I have with macOS Mojave is iCloud not syncing. In reality, this a common problem as it pops up every time Apple releases a new software update. To fix this, open System Preferences on your Mac, then select iCloud and hit Sign Out. Now sign back in to see if the problem is dealt with.

If the problem still persists, then remove the CloudDocs folder in the Finder. To do this, open Finder on your Mac > Go > Go to Folder, then find the CloudDocs folder and delete it.

Stay Up-to-date

Apple just released  MacOS Mojave 10.14.5 to all Mac users out there. The new update brings about several bug fixes and AirPlay 2 support for Samsung smart TVs. To get the update, open System Preferences on your Mac, then select the Software Update panel and hit the Update Now button.

Make sure you create a backup of your Mac using Time Machine in case something goes wrong during the process.

T2 Chip Problems

Last year, Apple brought its security T2 chip to its MacBook lineup after relentless rumors. Basically, the T2 chip takes care of the same tasks as its predecessor, but Apple has added things, making it more powerful. However, the T2 chip more of an annoyance than a help as it is causing some software problems in macOS Mojave.

Luckily, Apple recently released a supplemental update that addresses T2 chip problems in MacBook Pro. Apple says that the new update covers all MacBook Pro models (2018 or newer). This is the first supplemental update for macOS 10.14.5 after its launch event.

The T2 chip is expected to power Apple’s future Macs. The MacBook Pro 2019 features an improved T2 chip for enhanced FaceTime camera and improved exposure control.

Wrapping Up

macOS Mojave is getting better and smarter thanks to a series of software updates that Apple has begun rolling out since day one. However, there are times when macOS Mojave fails to respond. Hopefully, our solutions work for you.

Let us know in the section below if you are dealing with another issue that we have covered.

  1. I have to mention that Mojave is the first time I’ve been ashamed of being a Mac fan. It’s weirdly slow. Apparently many people are complaining. We depend on Apple to figure out these things before we get the product.

    At the same time I’m using Enhanced Dictation, the dumbest dictation software I can imagine. It’s as if we’ve going back 10 or 20 years.

    Skip the bells and whistles. Give us what we want–speed.

    And the suggestions on this site are not helpful. I checked the activity monitor. It said machine is 90% idle. So why is everything creeping around? Given the limited instructions, I would be afraid to delete/change anything.

  2. I have disappearing Printers in Mojave 10.14.5. The Printers are still showing in the Library Printer Folder, but they come and go, esp. after Restart or Starting from Shutdown. I’m also having problems with my external drives being ejected (not the right way).

    • Hi Steven, that’s frustrating. Can you give me more information of the problems you’re having with the external drives ejecting the wrong way please?

  3. I had huge issues with beach balling and slow start up. Tried everything. It ended up being my font library. After removing them and reimporting using font software, Mojave is running perfectly.
    I didn’t see any reference to fonts being an issue in any of the (many) articles I read….so hopefully this might help!!
