The newest operating system by Apple is the MacOS Mojave. This is packed with many cool features including a new dark mode, desktop stacks, new applications, and a revamped Mac Store. With these and many other cool features, it is no wonder that many people want to try it out. The problem is that as soon as one makes the update, the MacOS Mojave slows. Have you been asking yourself; “why is my Mac so slow?”
The first reason could be that the macOS Mojave does not support your device. This is the case if your Mac is a version made earlier than 2012. If this is the reason for slow Mac, the only solution is to forget using the Mojave because it is not compatible with such Macs. What if your Mac is a supported version, but it is still slow after Mojave update? There are many reasons for this and even more solutions you can try. This tutorial will educate you on all the reasons why your Mac is slow after Mojave update and give you solutions that work.
How to Speed Up macOS Mojave 10.14
There is a tendency for Mac running slow immediately after a Mojave 10.14 update. What could be the reason? The truth is that there could be many reasons but the best part is that there are many solutions you can try. Simply use the options given in this tutorial, and you will have your Mac running at fast speeds just like when it was brand new.
1. Use the Activity Monitor to Disable Power Hungry apps
Is your Macbook slow after Mojave update for no obvious reason and fans are blazing at high speeds? There could only be one explanation for the slow Mojave; power hungry background apps are running. These take up a lot of RAM and CPU space leaving little for the operating system. This causes the OS to be very slow in executing even the simplest tasks and commands.
To stop any power-hungry apps from making your Mac slow, you can use the Activity monitor. To open this, go to “Applications” then “Utilities”. Double click on “Activity Monitor”. This action will launch it.
To find applications taking up too much CPU space, click on the “%CPU” column. Look for the app using up most of the CPU. Are you using it? If not, stop it by selecting it then clicking on the “X” at the left top corner. To see apps taking up too much memory space click on the memory tab and use the same process to stop these apps.
Choosing the “Quit” option saves all changes then closes the application but this takes a while. On the other hand, “Force Quit” shuts down the application immediately, but all unsaved changes are lost. The latter is the most effective option, and the effects are immediate. This means that the macOS Mojave speed will improve immediately.
2. Clean up your macOS Mojave
One of the leading reasons for Mac slowing down is having too much information stored on the Mac. As you store files on the hard drive without deleting any, more and more space is used to store this data which leaves a small space for the macOS Mojave to operate in. This causes the OS to be slow and have sluggish performance.
To clean the Mac up, you need to go through the files and delete the ones that you do not need. Removing them will give your new OS enough breathing space for it to perform optimally. Deleting files manually can be tiring and at time ineffective. You may not know where to find logs and temporary files for the various apps as well as other files that take up too much space.
To delete these, a third party app may be required to clean up the Mac. In just two clicks, CleanMyMac 3 will be able to get rid of all the junk in every inch of the computer’s hard drive. You can choose to clean everything up or choose the kinds of material you want to be removed. The categories include large and old files, trash bin data, iTunes junk, mail attachments, photo junk, and system junk. The best quality of this cleanup software is that it is smart. This means it only cleans up what is needed without affecting the critical system files. Your Mac will operate normally while CleanMyMac keeps your hard drive free from any junk. This will increase Mac’s speed because there will be lots of free storage.
2. Moderate the UI Experience
The user interface in the Mojave has been improved and is better with more customizable settings. However, going all in on the user experience will come at the expense of having to deal with a slow computer.
Great effects like the transparency will heavily impact on the computer’s resources, and this will leave you with slow Mojave. The situation worsens when you need to multitask. So, to avoid this or remedy an already slow macOS Mojave, follow the following steps:
1. Go to “System Preferences” then click on “Accessibility”.
2. Click on “Display” and check the box next to “Reduce transparency” and “Reduce Motion”.
3. Update Software
Old software that was compatible with the High Sierra or the old OS X you were using may not be compatible with the macOS Mojave. If you have a Mojave slow, a simple update of the software you have on the Mac can help.
Install updates of the software and apps you have in the Mac so they are compatible with the Mojave and perform better.
To check for updates, click on “system preferences” then “Software Update”. If there are updates available, click on the “Update Now” button. The updates will then be downloaded and installed.
4. Use the optimize Storage feature
This is a cool feature that helps ensure all files on your drive are organized well and optimizing storage. This helps free up any unused disk space so it is available for use and all files are kept in order. To activate this feature, go to the Apple menu and then click on “About this Mac” then “Storage” then “manage”. You will at times see a message requesting to Store in iCloud, Optimize Storage, and Reduce Clutter. In the dialog box that appears click on “optimize”.
When activated, the optimize storage feature organizes files in the drive in different categories and removes any idle or unused files from the Mac. Whether it is an old application you no longer use, old screenshots and photos, old documents and text file, or any other thing not in use, this feature can detect it and take the appropriate action. With no clutter in your hard drive, it means there is more space for the Mojave to carry out its operations which makes the Mac very fast.
4. Manage Startup Items
Experiencing macOS Mojave slow login? This must be because there are too many startup items. These are the applications that launch every time the computer is switched on. While some apps like those that provide security need to be included in the startup items, others are just a nuisance that serves to slow down the computer without any real benefits.
To manage the startup items:
1. Navigate to the “System Preferences” then “Users & Groups”.
2. Click on “Login Items”. Choose the apps you would like to remove and then click on the “-“ button.
This removes all the selected items from startup and they will not launch every time you switch the Mac on. They can still be accessed by opening them when you need them. It is important to leave antiviruses among the startup items because you never want to have the Mac unguarded, even for a minute, as threats can take advantage of this gap. Keeping the number of startup items at a minimum will help the macOS Mojave maintain an optimal speed at all times.
5. Reset SMC and NVRAM/PRAM
When corrupted, the SMC and PRAM can make a Mac slow down considerably. When this happens, these need to be reset.
The System Management Controller (SMC) is in charge of things like hardware such as fans and batteries. As for the procedures to follow to set this, it will depend on the kind of Mac you are using.
Reset SMC on MacBook Air, MacBook Pro or MacBook
1. Power the Mac down and unplug the power cable.
2. Wait 15 seconds then plug the power cable in.
3. Press left shift, option, control and power buttons at the same time. Hold down for at 10 seconds.
4. Release all keys and power the Mac on as usual.
Rest SMC on iMac, Mac Pro, Xserve or Mac Mini
1. Power the Mac down and unplug the power cable.
2. Wait for 15 seconds and then plug the power cable in.
3. Wait for 5 seconds then turn the Mac on.
NVRAM/PRAM should be reset when there is an issue with Mac’s screen resolution, wrong battery charge reports or the Mac booting with the wrong disk. To do this:
1. Power the Mac down and leave it for a few seconds.
2. Switch the Mac on and press Option, Command, P and R keys on the keyboard at the same time.
3. Hold the keys down until the Mac restarts and hear a beeping sound.
These procedures will not cause any data loss when performed on the Mac so perform them with confidence.
6. Upgrade the Mac’s HDD to SSD
One of the best ways to speed up macOS Mojave is to run in it on a solid state drive (SSD) rather than Hard Disk Drive (HDD). The latter is slow. If your Mac has a hard disk drive, replace it with an SSD drive or, better yet, combine the two. You can use the SSD for running the Mojave and the HDD for storing files.
SSDs do not use the mechanical methods used by HDDs and hence the prior are faster in storing and retrieving of information. An easy way to install an SSD into an old Mac is by using a custom adaptor to replace the optical drive. You can then install the SSD on the custom adaptor and then install macOS Mojave and its applications on it.
7. Maximize on iCloud Storage
If you have a Mac that is fitted with an SSD drive that has a small capacity (128 or 256 GB), use iCloud to maximize storage. Simply save some files on iCloud and this will save space on the drive in the Mac. With more space for the Mojave to operate, it is fast.
iCloud backup is preferred because the data stored in it can be accessed at any time and from anywhere. The data can be retrieved when needed and used as required. On the downside, iCloud automatically syncs and deletes files that are not used often. The best choice is to use this and still have an external offline backup.
8. Disable New Dynamic Desktop
This is a cool feature in the macOS Mojave that makes the desktop change automatically depending on what time of the day it is. While this feature is cool and brings this OS to life, it consumes a lot of battery power because of the frequent location tracking it needs to do. This also tends to slow down the Mac. Turning this feature off ensures the Mac runs faster and saves battery.
How do you disable the new dynamic desktop?
1. Click on the Apple menu.
2. From the menu that will appear, click on “System Preferences”.
3. Click on “Desktop and screensavers”.
4. Select the wallpaper you want and set it.
9. Confirm that your Mac is compatible with macOS Mojave
Like with every operating system out there, the macOS Mojave has its minimum hardware qualifications. While some Macs have these qualifications, others are not so lucky. Generally, if your Mac was released before 2012, you cannot use the Mojave. Trying to use it will only result in very slow operations.
The comprehensive list of supported devices has the following:
Mac Pro (late 2013)
iMac Pro (2017 or later)
iMac ( late 2012 or later)
Mac Mini (late 2012 or later)
MacBook Pro (Mid 2012 or later)
MacBook Air (Mid 2012 or later)
MacBook (Early 2015 or later)
Macs made before these do not have enough graphics power and other qualities needed for the optimal running of the macOS Mojave.
Many things can make the Mojave slow down ranging from having too much on the drive to a corrupted SMC. No matter what the cause is, it needs to be established so that the right solution is applied in solving the problem. Try to analyze the situation and note when the Mac is at its slowest. This will help determine the reason why the Mac is slow and you can make the right decision on the course of action to take. Try any of the above steps to speed up your macOS Mojave or a combination of several and you will have a fast Mac within no time.
