Many Mac users have a complaint that macOS Mojave iMessages not working. Today morning I tried to send a message. When I am sending messages, it shows “Not Delivered”. But I can receive messages. One of the Mac users said some solutions to fix this issue. Here I am going to share those solutions with you. Solution 1: Check your internet.
- Apps and Security Changes in Mojave macOS Mojave has added security and privacy capabilities that can prevent apps that haven’t been updated for Mojave from running correctly. The specifics vary by app, but generally speaking, if you have an app that fails to launch, or launches and freezes, and the app used to work in one of the recent.
- After updating to Mojave, many Mac users see a message saying that an app they are trying to use needs to be updated and won't work with future versions of macOS. By future versions, that means the next major update of macOS, probably coming in late 2019, not minor updates. Before then, you can update to a newer version of that app, or find an alternative app to use in its place.
Have you ever tried updating to macOS Mojave, and then the installer returns with the message “An error occurred installing macOS” after running for a few minutes?
In another case, you might find that your MacBook suddenly becomes unresponsive after installing Mojave, taking so much time performing otherwise simple tasks. The show ends with the spinning beach ball of death appearing, staying for a few minutes.
Know that you’re not alone – the macOS Mojave install error has happened to a number of users, and it doesn’t take a lot for them to realize that the problem is likely related to the OSInstallerSetup and the whole process of migrating to Mojave in general. This article aims to be your quick guide to navigate this problem and address it in no time.
A Quick Reminder Before Troubleshooting
The macOS Mojave install error has been identified as a hardware failure in some instances, given the user’s inability to reinstall the operating system despite following the reinstall procedure correctly. Some users, for example, have received this mac error message while attempting to reinstall: “com.apple.OSInstallerSetup.error error 702.”
Below are some quick steps you can follow to solve this issue. Before going further, however, make sure that your computer is in generally good shape. A reliable third-party tool such as Outbyte MacRepair can scan it for all types of junk, optimize your RAM, and eliminate space hogs safely in order to help you proceed with the troubleshooting efficiently.
Ways to Fix the macOS Mojave Install Error
Let’s get to work and try the following steps to address the problem:
Install Mojave Using a New User
To do this, disconnect any external device from your Mac computer, such as audio devices, an external hard drive, and other peripherals. Next, try to install the software using a new user. Here are steps to create a new account for testing:
- Choose Apple menu > System Preferences > Users & Groups.
- Click the lock icon, and then enter an administrator name and password.
- Click the + (Add button) found below the list of users.
- Complete the fields for a Standard or Administrator account.
- Click Create Account or OK.
- Log out of your existing account and log in with the new one. Do this by choosing Apple menu > Log out.
- Once at the login window, log in with the new account’s name and password. If you’re prompted to sign in using an iCloud account or Apple ID, skip that step.
Once done, delete the installer file and then re-download it from the Mac Store.
If the issue still happens while you’re in the new account, then that means there’s something actually going on. At this point you can try the succeeding steps.
Check Your Software Version
Are you sure that your software is up to date? If you’ve already upgraded to Mojave, keep it up to date by following these steps:
- Choose Apple menu > System Preferences. Click Software Update to check for updates.
- If new updates are available, click Update now to install them. Choose More info to find out details about every update and select specific ones to install.
If your Mac is up to date according to Software Update, then that means all macOS apps are also up to date, including Safari, Books, iTunes, Messages, Calendar, Mail, FaceTime, and Photos.
You can also get updates for earlier macOS version such as High Sierra, Sierra, and El Capitan by following these steps:
![App App](/uploads/1/2/6/5/126502387/116289754.png)
- Open the App Store app.
- Click Updates located in the App Store toolbar.
- Using the Update buttons, download and install any updates listed.
Use Safe Mode
It’s also worth trying the Safe Mode option to resolve the issue. Also known as safe boot, it’s a way of initiating your Mac in a way that certain checks are done and the software is barred from automatically loading or opening. It can verify your startup disk and try to repair directory issues, as well as delete font cashes, kernel cache, and other system cache files.
Follow these steps to start up in safe mode:
- Start or restart your Mac. Afterwards, immediately press and hold the Shift key. At this point, the Apple logo should appear.
- Release the Shift key once you see the login window. For those whose startup disk is encrypted with FileVault, the user might be asked to log in twice.
- Leave in safe mode by restarting your Mac – no need to press any keys during startup.
Now, try to install the macOS update in safe mode.
Check for Hardware Issues
Apple Diagnostics assists you testing your machine for hardware issues. Once you have isolated the issue as a possible hardware problem, you can follow these steps:
- Disconnect all external devices except your mouse, keyboard, display, Ethernet connection, and AC power connection.
- Keep your Mac on a hard, flat, and stable surface that has proper ventilation.
- Shut down your computer.
- Turn it one, and then immediately press and Hold the D key on the keyboard. Keep doing it until a screen asking you to choose your language appears.
- The check lasts up to three minutes. If there is an issue found, Apple Diagnostics suggests solutions as well as offers references codes, which you should note before proceeding.
- Choose from the following options:
- Repeat the test by clicking Run the test again or pressing Command-R.
- Click Get started or press Command-G for further information.
- Restart your Mac by clicking Restart or pressing R.
- Click Shut down or press S to shut it down.
Check for Software Issues
Is it a software issue bugging your system and resulting in the macOS Mojave install error and subsequent problems with using your computer? Follow the instructions on this Apple Support page to address the issue depending on whether it occurs in just one app, in different apps, or in Mac OS X.
Clean-Install macOS Mojave

Fix computer troubles by downloading the compatible tool for your device.Imagine this: you’re working happily on your Mac when the dreaded beach ball of death appears. A program stops responding or worse, the macOS (or OS X) itself refuses to do anything but stare at you, blankly. You have a frozen Mac app or an OS X freeze. Mac OS not responding can lead to lost productivity or even lost work. Let's go over why it happens, what to do when your Mac freezes or when an Mac OS app stops responding, as well as some tips for preventative maintenance.
We’ll go over frozen apps first, so if your whole Mac freezes, you can jump to the part about fixing a frozen Mac.
Fixing a frozen app: Why Mac OS apps freeze
There can be a few reasons why apps freeze on Mac. First, sometimes an app freezes on its own, and sometimes it takes down the whole Mac with it. Here's what could be happening:
- Apps freeze in the background.
This could mean there are some apps running that you didn't open, they opened themselves. Probably, they're featured in your startup items, so they automatically launch when you start your Mac. If this happens repeatedly, you need to check what apps are running in the background and launch with the startup. - Processes freeze in the background.
This one is different from apps. One app may be running multiple processes, also system processes can be running on their own. - Too many apps and processes running.
Same logic as with the previous issue. But the question here is how many is too many? There is no definite answer to this, it very much depends on the hardware capacity of your Mac. You can read how to check it and fix it below. - Mac system is too cluttered with junk to run even simple tasks.
This is fixable, you can get a Mac optimizing app like CleanMyMac X for the job. Run a scan to find and remove the stuff you don't need, and there's a high change your apps will stop freezing after that.
What to do if an app freezes on your Mac
A frozen app becomes unresponsive and brings your work to a halt. In the worst case scenario, it can lead to lost work or a corrupted file. Fortunately, there are several options to try, and most are quite simple. Here’s what you can do when a program freezes on your Mac. First, you need to quit it. Then, if the app keeps freezing when you launch it, try the next options.
How to quit a frozen or unresponsive program
Quitting and then re-starting an app is a good way for Mac OS to handle a crash. You can do this from the OS X Dock or from the Force Quit window. To force-quit an app from the OS Dock, follow these simple steps:
- Click anywhere outside of the program
- Right-click (or Control-click) on the frozen app’s icon in the Dock. A menu appears.
- Hold down the Option key on your keyboard so that Quit in that menu changes to Force Quit.
- Select Force Quit.
That’s it. The app is instantly closed. Re-launch it and try again. If you prefer to work with the Dock hidden — or if the Dock itself is unresponsive — you can simply bring up the Force Quit dialog box to perform the same task.
Here’s how:
Here’s how:
- On your Mac’s keyboard, hit the Option, Command and Escape keys simultaneously (alt + ? + esc).
- The Force Quit dialog box appears with a list of running programs.
- Select the frozen app and then click Force Quit.
- The software will stop running and you’re free to re-launch it at this point.
If you’re using a maintenance utility like CleanMyMac X, it has freezes covered. When CleanMyMac spots an unresponsive app, a notification window with a Quit button pops up, so you could force-quit the app without rummaging around in its menu.
CleanMyMac keeps an eye on other performance issues, too, so if you'd like to get alerts like this one when anything goes wrong, download CleanMyMac X for free and give it a try.
How to fix Mac apps that keep freezing
First, check what apps are running in the background and launch with the startup.
To do it go to Settings > Users and Groups > Login items.
Uncheck anything you think might be causing trouble. In fact, just to be sure, uncheck every app and restart your Mac.

Uncheck anything you think might be causing trouble. In fact, just to be sure, uncheck every app and restart your Mac.
Now, find out which process or program is causing the problem. How to see what programs are running on Mac in general? You need launch Activity monitor.
How to find Activity Monitor on Mac: You can do it via the Spotlight Search or just open Launchpad and type it in.
How to open Activity Monitor in Finder: launch it from Applications > Utilities folder > Activity Monitor.

How to open Activity Monitor in Finder: launch it from Applications > Utilities folder > Activity Monitor.
When it opens, you'll probably see hundreds of processes in each tab, but the ones you need now are CPU and Memory tabs. Click on the % CPU sign to sort processes by their influence on your Mac's work. The heaviest ones will show up on the top. They could be your main issue, but don’t rush to deal with them. Some, like kernel, are important system processes and you shouldn’t mess with them.
How to kill a process on Mac OS
However, sometimes your problem does lie within a specific process, you can force quit it (Apple doesn't call it 'to kill a process on Mac', they make it sound fancy). But we're not at Apple HQ, so here's how to kill a Mac OS process:
- Open Activity Monitor.
- You see a list of processes. You can sort them by clicking on %CPU or % Memory in relevant tabs.
- Find the process you want to kill and choose it.
- Click on the octagon with an X sign.
- Done.
Occasionally the problem isn’t with the Mac app, but with the Mac OS itself. If you’re experiencing troubles regularly, it’s time to ask why your Mac keeps freezing. There are several possible reasons, so let’s start with the simplest potential solution.
First, the file you were working with at the time of the freeze may be the issue. To help determine if this is true, try opening a different file with that app and work with it for a while. If it behaves normally, quit and then go back to the file you were working with at the time of the crash. If the errant behavior persists, you may have found your problem. Salvage what you can into a new file.
Make sure that your software and OS X are up-to-date. This is easy to do with software purchased from the Mac App Store. The same goes for OS X. Launch the Mac App Store on your Mac, and you’ll see the list of pending updates, including any for the OS X itself. For third-party software purchased outside of the App Store, visit the manufacturer’s website.
What to do if Mac OS X freezes
If you cannot force-quit a program, or if the Mac OS is completely unresponsive, it’s time for the most obvious action — a reboot.
You can bring up the Restart/Sleep/Shutdown dialog box instantly by hitting Control plus the Power button. Option four, Shut Down, is selected by default.
Alternatively, you can press and hold the Power button for 1.5-2 seconds to bring up the same dialog box. If things aren’t hopelessly messed up, you’ll get a chance to save your work before your Mac shuts down. If that still doesn’t work, a more drastic option is available.

How to force reboot a frozen Mac
Press Command ?, Control and Power (on earlier MacBook models, use the Media Eject key instead of the Power button) to restart your Mac immediately. Best mac address changer software. Note that you won’t have the option of saving anything in this scenario, but it will definitely reboot your icy Mac.
Once your Mac has restarted, you might find that the hard restart has corrupted the file you were working on. Salvage what you can from it and create a new file.
How to fix a frozen Mac
After the reboot, ensure that your Mac has enough free hard drive space for the OS X, and enough free RAM to do what you want. CleanMyMac X can help you here, too. It removes all the useless files that take up space on your hard drive: app leftovers, mail attachments, cache files, and so on. That way, you can free up additional disk space for the OS X without deleting any of your own files. Plus, CleanMyMac X keeps tabs on how much RAM you’re using and lets you free some up with a tap.
Finally, if system cleanup also fails to fix the problem, you can try to run a clean install of your Mac OS. Just follow the instructions: How to clean install macOS Sierra 10.12
Note: If you don’t know which system your Mac runs, click the apple icon in the top left corner and choose About this Mac. You’ll see the name on the popup window.
That’s it, we hope this guide has helped you fix a frozen Mac. Remember, with day-to-day maintenance, your Mac can offer years of reliable work. On the rare occasion of a frozen program or even frozen OS X, these tips will help get you working and productive again. And software like CleanMyMac X can do some of the monitoring and maintenance for you, so you can focus on what needs to be done.
