The macOS Catalina installation should take about 20 to 50 minutes if everything works right. This includes a speedy download and a simple install with no issues or errors. Best case, you can. Create a clean installation file of macOS 10.15 Catalina. If you have got this far and find your macOS Catalina still running slow, this might be the option for you. What this does essentially is wipes off all the data on your hard drive and installs the macOS from a USB Insaller.
At the 13:00 minute timestamp you can see the very easy post install process. If you did use a Catalina Mac to create your USB installer, it's a good idea to go back and re-enable SIP (csrutil enable) on the Mac you used. When installing 10.15.6 use Unibeast 10.3.0 and Clover r5119.
So, you’ve decided to download an older version of Mac OS X. There are many reasons that could point you to this radical decision. To begin with, some of your apps may not be working properly (or simply crash) on newer operating systems. Also, you may have noticed your Mac’s performance went down right after the last update. Finally, if you want to run a parallel copy of Mac OS X on a virtual machine, you too will need a working installation file of an older Mac OS X. Further down we’ll explain where to get one and what problems you may face down the road.

We’ll be repeatedly referring to these Apple OS versions below, so it’s good to know the basic macOS timeline.

STEP 1. Prepare your Mac for installation
Given your Mac isn’t new and is filled with data, you will probably need enough free space on your Mac. This includes not just space for the OS itself but also space for other applications and your user data. One more argument is that the free space on your disk translates into virtual memory so your apps have “fuel” to operate on. The chart below tells you how much free space is needed.
Note, that it is recommended that you install OS on a clean drive. Next, you will need enough disk space available, for example, to create Recovery Partition. Here are some ideas to free up space on your drive:
- Uninstall large unused apps
- Empty Trash Bin and Downloads
- Locate the biggest files on your computer:
Go to Finder > All My Files > Arrange by size
Then you can move your space hoggers onto an external drive or a cloud storage.
If you aren’t comfortable with cleaning the Mac manually, there are some nice automatic “room cleaners”. Our favorite is CleanMyMac as it’s most simple to use of all. It deletes system junk, old broken apps, and the rest of hidden junk on your drive.

STEP 2. Get a copy of Mac OS X download
Normally, it is assumed that updating OS is a one-way road. That’s why going back to a past Apple OS version is problematic. The main challenge is to download the OS installation file itself, because your Mac may already be running a newer version. If you succeed in downloading the OS installation, your next step is to create a bootable USB or DVD and then reinstall the OS on your computer.
How to download older Mac OS X versions via the App Store
If you once had purchased an old version of Mac OS X from the App Store, open it and go to the Purchased tab. There you’ll find all the installers you can download. However, it doesn’t always work that way. The purchased section lists only those operating systems that you had downloaded in the past. But here is the path to check it:
- Click the App Store icon.
- Click Purchases in the top menu.
- Scroll down to find the preferred OS X version.
- Click Download.
This method allows you to download Mavericks and Yosemite by logging with your Apple ID — only if you previously downloaded them from the Mac App Store.
Without App Store: Download Mac OS version as Apple Developer
If you are signed with an Apple Developer account, you can get access to products that are no longer listed on the App Store. If you desperately need a lower OS X version build, consider creating a new Developer account among other options. The membership cost is $99/year and provides a bunch of perks unavailable to ordinary users.
Nevertheless, keep in mind that if you visit developer.apple.com/downloads, you can only find 10.3-10.6 OS X operating systems there. Newer versions are not available because starting Mac OS X Snow Leopard 10.7, the App Store has become the only source of updating Apple OS versions.
Purchase an older version of Mac operating system
You can purchase a boxed or email version of past Mac OS X directly from Apple. Both will cost you around $20. For the reason of being rather antiquated, Snow Leopard and earlier Apple versions can only be installed from DVD.
Buy a boxed edition of Snow Leopard 10.6
Get an email copy of Lion 10.7
Get an email copy of Mountain Lion 10.8
The email edition comes with a special download code you can use for the Mac App Store. Note, that to install the Lion or Mountain Lion, your Mac needs to be running Snow Leopard so you can install the newer OS on top of it.

How to get macOS El Capitan download
If you are wondering if you can run El Capitan on an older Mac, rejoice as it’s possible too. But before your Mac can run El Capitan it has to be updated to OS X 10.6.8. So, here are main steps you should take:
1. Install Snow Leopard from install DVD.
2. Update to 10.6.8 using Software Update.
3. Download El Capitan here.
“I can’t download an old version of Mac OS X”
If you have a newer Mac, there is no physical option to install Mac OS versions older than your current Mac model. For instance, if your MacBook was released in 2014, don’t expect it to run any OS released prior of that time, because older Apple OS versions simply do not include hardware drivers for your Mac.
But as it often happens, workarounds are possible. There is still a chance to download the installation file if you have an access to a Mac (or virtual machine) running that operating system. For example, to get an installer for Lion, you may ask a friend who has Lion-operated Mac or, once again, set up a virtual machine running Lion. Then you will need to prepare an external drive to download the installation file using OS X Utilities.
After you’ve completed the download, the installer should launch automatically, but you can click Cancel and copy the file you need. Below is the detailed instruction how to do it.
STEP 3. Install older OS X onto an external drive
The following method allows you to download Mac OS X Lion, Mountain Lion, and Mavericks.
- Start your Mac holding down Command + R.
- Prepare a clean external drive (at least 10 GB of storage).
- Within OS X Utilities, choose Reinstall OS X.
- Select external drive as a source.
- Enter your Apple ID.
Now the OS should start downloading automatically onto the external drive. After the download is complete, your Mac will prompt you to do a restart, but at this point, you should completely shut it down. Now that the installation file is “captured” onto your external drive, you can reinstall the OS, this time running the file on your Mac.
- Boot your Mac from your standard drive.
- Connect the external drive.
- Go to external drive > OS X Install Data.
Locate InstallESD.dmg disk image file — this is the file you need to reinstall Lion OS X. The same steps are valid for Mountain Lion and Mavericks.
How to downgrade a Mac running later macOS versions
If your Mac runs macOS Sierra 10.12 or macOS High Sierra 10.13, it is possible to revert it to the previous system if you are not satisfied with the experience. You can do it either with Time Machine or by creating a bootable USB or external drive.

Is your mac starts getting slow after updating to macos Catalina os x ? or the performance of your MacBook Pro or air has been low now. In this guide will tell you how to fix slow Catalina os x performance.
Before anything else, one thing to suspect is that your physical Mac laptop or desktop doesn’t actually support this latest edition of macOS. This could certainly be the case if your Mac was made before the year of 2012 as it won’t be compatible with macOS 10.15 Catalina. If you find yourself finding that this was the reason why the only solution you’ve got really is to disable some of the new features that came along with Catalina to see if that starts to speed up the computer. However if this reason doesn’t apply to you and your Mac does indeed support Catalina, all is not lost. There are plenty more things we’re going to be able to try to try and speed up your Mac OS system. Throughout this tutorial, we’re going to be looking at first and foremost the reasons why your macOS Catalina slow, and secondly what you can do to fix these issues.
How to speed up macOS Catalina
It is actually to be expected for your Mac to be running slow should you have just gone through the process of installing macOS 10.15 Catalina. This might be expected; however, there isn’t one single reason why this should be expected. Instead, there are many reasons and solutions that you can try to try and speed your slow macOS Catalina and get it running back to speeds you expect an updated Mac OS Catalina too. The hunter mac download.
1. Disabling Your Start-up items
When you’re switching your Mac on from it being turned off if you find that it takes forever and a day to boot up this can sometimes cause frustration and stress that you could really have done without. However, all is not lost, there is a solution to speed up the boot process of your Mac OS. Before finding what solution will fix the problem first, you’ll need to find the reason why macOS Catalina slow login. For your benefit, we are going to look at every problem and solution individually so that you know which will work for you.
Try disabling programs that automatically run:
When you first boot up your Mac, there are a series of programs that will just start up themselves automatically without you even noticing. These ‘start-up’ items will always start themselves upon the Mac being switched on unless you tell them to otherwise. The reason that this could be the culprit is that they’re all starting up at the same time upon the machine being switched on and this congestion causing the system to slow down. If you want to stop these programs automatically starting up to follow these steps:
Disable Startup Items on Catalina
1. Click on the Apple Menu in the top left of your screen.
2. Navigate to ‘System Preferences’.
3. From here select ‘Users and Groups’.
4. Now you’re going to want to click your username that should show up on the right-hand side of the screen. After you’ve clicked that, go to the left and click ‘login items’. Now once you’ve done this, it will show you the list of programs that automatically start up when you switch your machine on.
5. Tick the boxes of the programs that you don’t want to automatically, once you’ve made all of your selections click the minus (-) that should be located at the bottom of your window.

Try disabling start-up items that are hidden
Not all of the programs that start up automatically upon boot are visible. Some of these start-up programs are what we call “hidden”, and for this reason, you might not have already disabled them, and thus they will still be having an impact on the speed of your Macs boot. To resolve this issue, we need to use the Optimization feature that is located in the program called Clean My Mac. Navigate to the program and then follow these steps:
Disabling Hidden Startup items
1. Navigate to the speed tab and select this.
2. Next, find optimization, select it and then click “Launch Agents”. From here you will now see a list of service applications that run automatically when your Mac boots up. What you’re going to want to do now is disable every single one of these applications of alternatively remove them.
Now that you have taken care of both the visible and hidden start-up items you might now notice an improvement in the speed that your Mac boots up should you have just upgraded to Catalina.

2. Resetting Both Your SMC and NVRAM/PRAM
If either your SMC or PRAM finds themselves in a state of corruption, this can have a devastating effect on the speed of your Mac boot up process. However, there is a way around this corruption, and that is to reset both of them.
Firstly let’s explain what SMC is. The System Management Controller is responsible for the smooth running of hardware such as fans inside your Mac computer. So you need to be careful to follow these steps carefully to reset this. And which set of steps you follow depends on what type of Mac you’re using:
To Reset your SMC on either a MacBook Air, MacBook Pro or a Macbook:
1. Firstly switch your Mac off altogether and remove the power cable.
2. Wait roughly around 15 seconds before plugging your power cable back in.
3. Without first switching on the Mac, hold the Left Shift, Option, Control and Power buttons all together at the same time for a minimum of 10 seconds.
4. Release all the keys and power on your Mac as usual.
If you need to reset the SMC on your iMac, Mac Pro, Xserve or Mac Mini:
1. First, you’re going to want to, in the same way as the previous, switch your Mac off and then unplug the power cable.
2. Leave the power cable out for 15 seconds before plugging it back in.
3. Wait a further 5 seconds and switch the Mac back on.
Reset your NVRAM or PRAM
You should only be needed to reset your NVRAM or PRAM if there is either an issue with the resolution of your Mac if it is reporting the battery as being at the wrong level or finally if you’re going to boot the Mac up and it’s going from the wrong disk. To reset follow these steps:
1. Switch your Mac off and leave it off for a few seconds roughly.
2. Switch your Mac back on and press the Option, Command, P & R Keys on your keyboard at the same time.
3. Keep these keys held down until you see your Mac restarting while making a beeping sound at the same time.
Don’t worry, resetting your NVRAM/PRAM will not cause you to lose any data at all.
3. Try Optimising your Storage
Optimize Storage with Catalina
This is an essential feature on a Mac that organises all of your files and ensures that your storage usage at all times is optimised and nothing is being wasted. It also helps free up and storage space so that you have more disk space is available for you to use. If you haven’t activated this feature you can do so by:
1. Go to the Apple Menu in the top left of your screen.
2. Click on ‘About This Mac’ and then to ‘Storage’ and finally ‘Manage’.
3. You should now see a pop-up message that gives you various options, select the option that says ‘optimise storage’.
Once this is now activated, the feature will by itself start organising your files efficiently into various categories and will remove any unused files from the system, therefore, clearing up space on your Mac. The reason that this will speed up your Mac is that the Catalina OS now has more space to work with and rely on for its operations so you should see a considerable improvement.
4. Clean up both Your System and App Junk
Another of the main reasons as to why your Catalina Slow could be that you have an abundance of junk files from your system in your current OS before updating to macOS 10.15 Catalina. This will have a domino effect and will start to slow your Mac down after you have updated your Mac.
It could also be that if you have recently installed a new app on your macOS 10.15 Catalina, this could be slowing down your OS. If there is a problem with your App Junk on your macOS and you don’t remove this app junk completely, this will then cause a conflict between both the old app junk and the new app junk.
Clean up both your System and App Junk
Macos Catalina Installation
If you find yourself needing to delete this app junk, you will have to use the services of a 3rd Party Application. An excellent app to use is called Clean My Mac, which will comprehensively remove all of the app junk from every area of your disk. However, you can choose between deleting everything or only selected areas of the disk. The best feature of this app is that it is intelligent in how it goes about the cleaning process, i.e. it will only clean up what is unneeded and won’t compromise your data or your Macs performance. Once you have removed these files, you should see an improvement in terms of the speed of your Mac.
5. Disable Apps that are Power Hungry using the Activity Monitor
If you’ve got to this stage and still not found the reason as to why your Mac is running slow after the Catalina update whilst at the same time noticing that the fans are spinning a lot faster than usual, then don’t worry there is a reason for this, and that is that applications are running in the background that requires a lot of power. As well as using up a lot of physical power these applications can also be greedy when it comes to RAM and CPU usage which then leaves less space for Catalina to operate on, meaning that the OS will start to run slower.
If you want to stop these applications from using up so much power, you’re going to have to make use of the Activity Monitor. To find this program navigate to ‘Applications’ and then ‘Utilities’. Here you will see ‘Activity Monitor’, double click on it to open up the application.
Disable Apps that are Power Hungry
You will see a range of columns at the top, click on the ‘%RAM’ column to see all of the programs that are taking up a lot of RAM usage. If you find that you’re not using this application, then you will be able to click an ‘X’ in the top left corner of the screen and clicking this will stop the app. Likewise, if you want to see all of the apps that are taking up too much CPU, then click on the CPU tab and repeat the same process again to stop these memory hungry applications.
When you select the Quit Options this will, in turn, save any changes you’ve made during the time of the window is open, and don’t worry if the window takes a while to close this is totally normal, however if you select the option ‘Force Quit’ the window will shut down a lot faster but you will have lost all of the changes you’ve just made.
6. Double check that your Mac is fully compatible with macOS Catalina
As we have touched on before some Macs are not compatible with specific versions of the macOS. With every release of a new OS comes a whole new set of hardware requirements. Gunbound classic aimbot 2011. Some of your macs out there might fulfil all of these requirements however some of you may not, and even if you try you will struggle to even use the Operating System it will be running at that slow of a speed, here is a lost of all the Mac devices that are supported by macOS 10.15 Catalina:
– Mac Pro (Late 2013 or newer)
– iMac Pro (2017 or newer)
– iMac (2012 or newer)
– Mac Mini (Late 2012 or newer)
– MacBook Pro (Mid 2012 or newer)
– MacBook Air (Mid 2012 or newer)
– MacBook (Early 2015 and newer)
Macos Catalina Installation Failed
If you’re Mac was made before any of the dates specified above unfortunately you don’t have the hardware requirements necessary to run macOS 10.15 Catalina and your only option is to upgrade your device with a SSD.
7. Moderate the User Interface Experience
One of the significant changes you might have noticed should you have already have upgraded to Mac OS Catalina is that the UI or User Interface looks massively difference, however with these changes comes some slowness in terms of speed. What we’re going to do now is the turn of QE/CI in Mac OS Catalina as features such as transparency will take up more of the resources of the computer, this, in turn, will leave less memory for Catalina to use resulting in a slower OS. To do this follow these steps:
Moderate the User Interface Experience
1. Go to “System Preferences” and then on “Accessibility”.
2. Next, go to “Display” and check the box next to “Reduce Transparency” and “Reduce Motion”.
9. Create a clean installation file of macOS 10.15 Catalina
If you have got this far and find your macOS Catalina still running slow, this might be the option for you. What this does essentially is wipes off all the data on your hard drive and installs the macOS from a USB Insaller. This means that you have no old app junk, no third party applications or users accounts and all the settings are set to default.
Bottom Line
Hopefully, this guide will have given you all the answers you could have wanted should you have found yourself feeling frustrated at your system running slow after updating to the latest macOS 10.15, namely Catalina. This guide has also run you through all the possible reasons and solutions should you be having these issues and once resolved, you should be able to use the OS at an optimal speed.
