Those who still rely on older Mac OS X operating systems, know these still are going strong. There are so many things you can do with past OS X — like Lion, Mavericks or Yosemite — each one of these operates flawlessly. So if you’re looking to give your Mac a fresh start with just a classic Mac OS X and nothing else, to clean install Mac OS from USB is the best option for you.

To clean install Mac OS from USB, there are three things you should do. First, you should clean up your Mac from the old baggage — system files that have piled up over time. Once it’s all cleaned up, the next you should do is backup your newly cleaned Mac. And finally, after doing a backup, you can clean install OS X of your choice from USB.

We’ve got the steps outlined below, so let’s get to it.

You will learn how to install OS X into a brand new SSD from the beginning, hardware and software steps! MacOS Big Sur elevates the most advanced desktop operating system in the world to a new level of power and beauty. Experience Mac to the fullest with a refined new design. Requires a MacBook Pro or MacBook Air with Touch ID, an iPhone 6 or later with iOS 10 or later, or an Apple Watch with watchOS 3 or later. Exchange 2013, or Exchange. May 23, 2020 The MacBook Pro was brought to me with a windows 10 bootcamp but the Mac OS portion is corrupt so it only boot to windows. When i was unable to install Mac OS Sierra on the hard drive so I removed the hard drive from the MacBook and format it in another MacBook with Mac OS extended journal format.

First, right-click the USB drive in Disk Utility and click “Erase.”. Format your USB drive as “Mac OS Extended (Journaled)” and choose the GUID Partition Map scheme. If you can’t find the option to set the partition table, make sure you’re selecting the “View - Show All Devices” option. Right-click on the USB drive, click Erase.

Step 1: Clean system junk on your current Mac OS X

Whatever OS X you are currently on, system junk and outdated cache files are a potential source for software conflicts. Having cleaned them up, you may discover around 35 GB of newly created space previously taken by junk. What's more, old caches may interfere with your new Mac OS X installation, so this step is pretty essential.

Cleaning can be done either manually or using a dedicated app. If you don’t want to spend the next 20 minutes on repetitive clicking and typing, jump right to the automatic solution further down.

The manual way to remove old user caches:

1. Click on a Finder window and choose “Go to Folder” in the Go menu.
2. Type in ~/Library/Caches and click Enter to go open the folder.
3. Go through each of the folders and remove their contents.

Note: Do not remove the folders themselves, just their insides.

Next off, do the same steps, but now replace...

~/Library/Caches with… /Library/Caches

Automatic solution for system junk cleanup

There are many nice apps that offer a quick Mac clean up. Among those, CleanMyMac 3 is our favorite as it looks most user-friendly of all. It scans your hard drive for old caches, broken apps, and app leftovers so you can remove all unwanted files in a minute or two. After all, a newly installed OS X feels better on a clean computer.

Download CleanMyMac and then follow the steps:

1. Launch CleanMyMac 3.
2. Click Scan.
3. Click Remove.

And you’re done. If you want to clean up more junk on your Mac, go through each of the modules located on the left panel of the app. It’ll help you clear out gigabytes of junk that you probably didn’t even realize were there. Once you’ve finished the cleanup, head to the next step.

Step 2: Back up your Mac

Before you begin to reinstall Mac OS from USB, you should back up your Mac. Note: If you don’t do this step, you will not be able to recover files, nor restore anything if something goes wrong. To back up your Mac:

1. Open an app called Time Machine.
2. Click “Select Disk.”
3. Select where you wish to save your files (an external drive works best, Apple Time Capsule is a safe bet).
4. Click “On” on the left-hand side of the screen to turn Time Machine on.
5. On the right, under the name of the storage device, there are three lines that say, “Oldest backup,” “Latest backup,” and “Next backup.” Your backup should be scheduled within the next 5 minutes.
6. Don’t want to wait? In the menu bar at the top of your screen, a few icons left of the Date & Time, click on the “arrow clock” icon and select “Back Up Now.”

Step 3: Installing Mac OS from USB

You will need 3 essential things:

• The OS X Installer (downloaded from the App Store)
• The backup of your old system
• Startup drive to install OS X on

Once it’s all prepared, it’s time to clean install OS X. But first, you need to create a bootable drive using a USB containing Mac OS X of your choice. Don’t know how? Then read on.

How to create a bootable USB flash drive

1. Connect your Mac to the USB flash drive. It should have at least 12 GB of available storage.

2. Open Terminal from the Utilities folder of your Applications folder.

3. Type or paste the following commands in Terminal:

Mavericks:

Yosemite:

El Capitan:

4. Press Return.

5. Type your administrator password and press Return.

6. When prompted, type Y to confirm that you want to erase the volume and press Return. You'll see the progress as the bootable installer is created.

7. Quit Terminal when the process is finished.

How to install the OS from USB

1. Plug in your bootable USB drive and Restart your Mac while holding the Option key. Make sure to keep it pressed down!

2. When it restarts, you’ll have a few options. Choose your USB Installer.

3. Next, select the Disk Utility option.

4. In the window, at the top of the left bar, select your Mac’s Main Drive.

5. Next, to the First Aid button at the top, click the Erase button.

6. Now, near the center of the window, select the Format drop-down list and select “Mac OS X Extended (Journaled)” as the type.

7. Click Erase (this will erase your main drive) and allow time for the drive to format.

8. When it’s finished, close out DiskUtility and select “Install OS X” from the menu.

9. Select your main drive and install a new OS X on it.

Follow the installation prompts and enjoy your new operating system. And if you want your new OS works smoothly for a long time to come, use a great cleaning and maintenance tool we've mentioned above — CleanMyMac 3. The app will take care of your Mac, so you'll get the most out of your computer again. Try it now!

It was the fall of my junior year in high school when my aunt bought me my first laptop. A brand-new MacBook Pro and I absolutely couldn’t believe it. As it turns out, this same computer is still running almost 10 years later; but is it running as efficiently? With a little tender, love, and care the answer has proven to be YES.

Upgrading an old MacBook Pro may seem like a monumental task, but it can be split up into two categories: software optimizations and hardware upgrades. This article will focus on software optimizations and we will cover hardware upgrades in another article.

It’s important to note, if you have an older MacBook you should NOT update the operating system to Mojave, there are many programs that run into compatibility and indexing issues. In most cases, you won’t even be allowed to.

These 7 simple tasks will significantly improve the speed and storage space on your MacBook Pro. Let’s get into it.

6. Limiting Startup Programs

Often times, the most common reason an older MacBook might take longer to boot up is because there are too many startup programs running in the background when the machine is first powered on. This is a simple fix and all you’ll need to do is this:

• Make your way to System Preferences
• Click on Users & Groups
• Click on the Login Items tab

If you see anything in the Login Items tab that you don’t what booted on launch, just click on that item and click the minus sign (-) at the bottom right under where it says To hide an application when you log in, select the checkbox in the Hide column next to the application. Disabling apps from starting on boot up has sped up my boot up time dramatically and it will for you as well.

5. Clear Your Desktop

A simple fix that you might not think of right away is clearing all of the items that are taking up space on your Desktop. If there are too many items and folders it might be worth it to consolidate all of those folders and files into a single folder that you can direct somewhere besides your desktop.

I used to have files scattered all over my desktop and even consolidating them to 7 folders dramatically improves my bootup and runtime speeds.

4. Deleting Large Files

Another huge problem that’s been known to curse the older MacBook is a rather obvious one: large unwanted files significantly slow down the performance of an older machine.

Usually, to make sure that annoying ‘beach ball of death’ stays in its cyber cage, you’re going to want to make sure at least 20% of your hard drive is free. To free up space you simply need to:

• Click on the Apple logo at the top left of your screen
• Select About This Mac
• Navigate to Storage (the third tab) and click Manage
• From here you should see the largest files and delete them accordingly.

If you are running OS X 10.11 (El Capitan) or earlier, you will not have the Manage button unfortunately. In this case, open Finder, click on All My Files in the left sidebar, and then sort by the Size column.

An important thing to note, iOS Files on the left were created before iCloud worked the way it does now. It’s an exact copy of an older phone or iOS device, which you should delete if you have iCloud enabled because iCloud does all of that remotely now.

It’s also important to mention iTunes because old movies or podcasts will take up a significant amount of space, so if you’ve already seen these movies you might want to consider deleting them afterward. After doing this I freed up approximately 30 gigs from my hard drive. The ‘beach ball of death’ is gone.

3. Clear the Cache

Clearing the system cache is something that I haven’t done in a while and it helped speed things up. To clear the system cache, you simply need to:

• Navigate your way to Finder
• From the Go tab at the top lefthand of the screen select Go to Folder at the bottom of the dropdownmenu
• To make your way to the caches directory,type this in exactly “~/Library/Caches” (without the quotation marks)
• Delete everything inside of the Cachesfolder. Any file that the computer needs will automatically be redownloaded, soyou don’t have to worry about deleting something important.

After doing this you should restart your computer and you’ll notice a dramatic change if you haven’t cleared the cache before.

2. Disable FileVault

Out of all of the tips I’ve seen for speeding up an older MacBook Pro, this one made the most significant change for me. FileVault is the OSX built in encryption feature that encrypts all of your files and data on your computer.

If you’re not a high-profile individual that needs a ton of security (like me), you will not need to have FileVault enabled. To disable this feature, you will need to:

• Navigate to System Preferences
• Select Security & Privacy
• Choose the tab FileVault
• Click on the Lock picture at thebottom left of your window to allow changes to be made to this setting and typein your administrator password to confirm.
• Select Turn Off FileVault…

An important note for this process:

Decrypting your information will take a LONG time, so it’s important you do this when you won’t need your laptop for a significant amount of time. I would recommend doing this before bed because it’s been known to take anywhere between 4 and 12 hours.

This tip made the most significant change for me because the decrypted data takes way less time to load. Disabling this also managed to free up 90.2 gigabytes of space for me so I completely recommend it.

1. Reset SMC and NVRAM

Another very impactful method for improving and upgrading MacBook performance is resetting the SMC and NVRAM. SMC or System Management Controller is responsible for battery management, thermal management, and many more hardware management services.

Resetting this might help solve overheating or battery issues you might be experiencing. NVRAM or nonvolatile random-access memory is, “the small amount of memory that your Mac uses to store certain settings and access them quickly” according to apple support. Resetting this was incredibly valuable for me because my hard drive is partitioned and NVRAM manipulates startup disk settings.

Your MacBook setup will probably be different than mine, so will your reset options.
