- There are a number of options to choose from here - you could recover your Mac from your last Time Machine backup, or perform a disk repair - but we recommend choosing the 'Install new OS' option.
- OS X El Capitan is taking very long to install. How do I speed up this process? By 'taking very long to install' do you mean - takes very long to download?
How to fix it: Update your macOS. Having the latest version of macOS is good practice (the latest version right now is macOS Catalina 10.15).Don’t think of it as adding more junk to your already slow Mac — think of it as new software that makes your Mac run more smoothly.
These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.
What you need to create a bootable installer
- A USB flash drive or other secondary volume, formatted as Mac OS Extended, with at least 12GB of available storage
- A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan
Download macOS
- Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server. - Download: OS X El Capitan
This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.
Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume that you're using for the bootable installer.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace
MyVolume
in these commands with the name of your volume.
Big Sur:*
Mac Os X Installer Disk
Catalina:*
Mojave:*
High Sierra:*
El Capitan:
* If your Mac is using macOS Sierra or earlier, include the
--applicationpath
argument and installer path, similar to the way this is done in the command for El Capitan.After typing the command:
- Press Return to enter the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
- When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.
Mac Os Installer
Use the bootable installer
After creating the bootable installer, follow these steps to use it:
- Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
- Press and hold the Option (Alt) ⌥ key immediately after turning on or restarting your Mac.
- Release the Option key when you see a dark screen showing your bootable volumes.
If you can't start up from the bootable installer, make sure that the External Boot setting in Startup Security Utility is set to allow booting from external media. - Choose your language, if prompted.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

createinstallmedia
command and the arguments that you can use with it, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:- Big Sur: /Applications/Install macOS Big Sur.app/Contents/Resources/createinstallmedia
- Catalina: /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia
- Mojave: /Applications/Install macOS Mojave.app/Contents/Resources/createinstallmedia
- High Sierra: /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia
- El Capitan: /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia
Every device sooner or later begins to run slower and slower. Even the Mac, which is a highly-efficient Apple product, starts to slow down and becomes a real pain to use over time. If you are a heavy Mac user this is especially true and you are more likely to experience performance issues.
There are several other reasons why your Mac might be running slower:

If you find that your Mac is starting to lag in performance, freeze up, or just acting strangely, it’s probably time to optimize it with an efficient Mac cleaning tool.
1. Mac Disk is getting full
Nothing slows down a Mac more than having too much on your hard drive. If you can increase available disc space on your Mac, you’re sure to see an increase in your Mac’s speed.
How to fix it: Clean up your Mac Disk
Unfortunately, doing this manually isn’t as easy as it sounds. Cleaning up old movie files, organizing your Desktop, and searching your Mac for old files you don’t need is the easy part. However, the hard part is cleaning up your system and figuring out all the stuff that can be safely removed for more space. The best option is to use a Mac cleaner, like Cleaner One Pro. It offers all-in-one Mac cleaning features including a disk cleaner for junk files, big files and duplicate files.
Uninstalling apps and deleting useless files from your Mac is easy, but the residual junk or cache files left behind often fill up your disk space and clutter the system. When the free space on your drive gets really low, your Mac stops operating efficiently and becomes very slow. Cleaner One Pro frees up your disk space by removing all the unnecessary and unwanted files in just one click.
2. Outdated Mac OS
Your Mac’s OS X is extremely important to how well it performs. An older OS X typically runs slower — that’s why Apple releases new OS X’s every year or so.
How to fix it: Update your OS X.
Having the latest version of OS X is a good practice (the latest version right now is MacOS Catalina 10.15.4). Don’t think of it as adding more junk to your already-slow Mac — think of it as new software that makes your Mac run more smoothly. So, head over to the Mac App Store download and install the latest version, once you’ve checked if it’s compatible with the model/year of your Mac. You’ll probably see a nice performance boost.
3. Startup is slowing you down
When you start your Mac, a lot of things get loaded in the background. Not only do they slow down your Mac on startup, but they continue to use up resources the whole time you’re using your Mac.
How to fix it: Manage your Startup Items.
Give your Mac a clean start and make OS X run faster. When you don’t manage your Startup Items, it’s like making your Mac run a sprint with a gigantic, book-filled backpack — it’s going to take a bit longer for it to get moving, right? Lighten the load on your Mac.
Speed up your Mac’s startup time by removing unnecessary startup apps. Go to your System Preferences > Users & Groups, then click your username. Now, select Login Items, click the name of an application you don’t need to launch during startup, then click the “-” symbol located below the list to the left. This will remove the application from the list and it will no longer be loaded on startup. This should help a lot to speed up your Mac’s long startup time.
4. Too many things running in the background
Due to increased workload, (for example, when you open multiple heavy applications simultaneously), your RAM tends to get cluttered. Your RAM should have enough space to read and write contents efficiently without any lag. When this memory gets low, your Mac system or apps may become slow or unresponsive.
How to fix it: System Monitor and Memory Free
Activity Monitor shows you which resources various processes are using on your system. Check the list of apps and processes that are running on your Mac in real-time. Quitting unnecessary apps that take up a lot of processing power could make a huge difference in speeding up your slow Mac. Be careful not to remove any critical or necessary processes!
Seems pretty complex, right? Yet there is a much simpler way to do this. With Cleaner One Pro you can easily monitor your system status. Cleaner One Pro’s smart activity monitor lets you easily view your system’s network usage and CPU usage in real time. This allows you to optimize your Mac on your own whenever you experience performance or speed issues.
5. Overloaded Browser Cache and History
![Installer Installer](/uploads/1/3/4/2/134202873/248290403.png)
Sometimes, even simple tasks seem to run slowly and you suddenly think ‘Why have I spent my precious dollars on this dumb device!’ Well, your anxiety is genuine but you can do something about it. There can be a number of reasons why your Mac is behaving this way and low hard drive space due to an overloaded system and browser cache may be one of them.
How to fix it: Clear Cache on Your Mac.
![Very Very](/uploads/1/3/4/2/134202873/983048522.png)
You can either clear your browser cache manually or you can use Cleaner One Pro’s simple one-click feature to do it for you.
