After thoroughly researching and trying various methods, we are bringing you a step by step guide which will help you in running Windows OS on your Android smartphone. You’ll be able to run Windows 7,8 or even Windows 10 using this method on your smartphone, provided your smartphone has some good specs to run it. Where XX:XX:XX:XX:XX:XX is the new MAC id that you want to change. Finally, to revert the MAC address to its original hardware value, run the following command: macchanger -p enp0s31f6. However, you don’t have to do this. Once you reboot the system, the changes will be automatically lost, and the actual MAC address will be restored again. Make sure the format is set to Mac OS Extended (Journaled) and the partition scheme is set to APFS. With the internal drive reformatted and ready, quit Disk Utility and select the internal drive as the installation destination. Then click Continue and let the installer run as you normally would. But to me, the most important aspect of Linux being a superior choice is its Open Source nature. And, most of the points discussed below are the direct advantages of an Open Source software. To briefly explain, you get to see/modify the source code yourself if it is an open source software. But, for Mac, Apple gets an exclusive control.

With the promise of increased functionalities and better performance, it is little wonder how droves of Mac users opted for the High Sierra, some of the users' expectations were however cut short as their Mac seemed to run on slow-mo immediately after this update.

How to Speed Up Your Mac after High Sierra Update?

With the uncontrolled hype of the macOS High Sierra update which is around its better data management, video streaming, and gameplay graphics, it is no wonder some Macs are running slowly to accommodate this update. Various issues have been linked to slow performances in Macs, such as full hard drive, system aging or the presence of too many applications running simultaneously. Although the specific reasons for slowing down the Mac might be unknown, the fixes for this problem have been identified and some of our trusted fixes are listed below:

  • 1. Use A Mac Optimization Software [100% Workable]
  • 2. Clean Hard Drive on Your MacBook
  • 3. Activate the Optimize Storage Option on Your Mac
  • 4. Decongest Your Mac Memory and CPU Space
  • 5. Reconfigure SMC & PRAM/NVRAM

1. Use A Mac Optimization Software [100% Workable]

A powerful Mac optimization software can help a lot for a slow Mac. It can efficiently optimize your Mac through some easier ways. Here we found the best Mac optimizer, which is called Umate Mac Cleaner. It is the leading cleanup tool to make your Mac run faster and improve its performance.

4 Ways to Get a Faster Mac with Umate Mac Cleaner

One of the main features of Umate Mac Cleaner is 'Speed Up Mac'，which comes with 4 options to get a faster Mac: disable the startup items, deacivate the heavy consumers, remove the launch agents and free up ram.

  • Disable Startup items: Disable startup items which automatically launch when you boot the Mac.
  • Deacivate Heavy Consumers: Deactivate heavy consumers that occupy CPU usage and memory.
  • Remove Launch Agents: Remove those launch agents that run secretly in the background and automatically start their parent programs.
  • Free Up Ram: Deactivate those processes or apps that are hogging lots of RAM on your Mac and create more space for it.

Why Umate Mac Cleaner Stands out Among Other Ways

  • 2x greater performance
  • 3x faster boot time
  • Extremely easy to use
  • Speed up Mac with just 1 click
  • Safe to use without affecting important data

How to Make Your Mac Faster with Umate Mac Cleaner

Step 1. Download and install Umate Mac Cleaner, and it's free to scan how many files can be cleared.

Step 2. Select 'Speed Up Your Mac' tab on the app and click the big 'Start Now' button for locating the items that you need to disable.

Step 3. Choose those items you want to disable and hit the 'Disable' button to accelerate Mac.

2. Clean Hard Drive on Your MacBook

Unlike the human brain that constantly deletes old and unnecessary data or files by itself, the Mac never automatically removes its data. The flaw of this design is that over time the limited space hard drive becomes congested and even filled up if nothing is ever deleted, hence frequent decongestion is advised.

Decongestion can be achieved via two methods, either manually or automatically. Manually, a user can go through the rigorous process of searching for and identifying all redundant files and documents on his device and delete them manually. However, compared to the automatical way, this is rather time and energy consuming.

Referring to tools such as Umate Mac Cleaner that could really help, which can automatically identify redundant and hidden files and then delete them, freeing up space on your hard drive to improve Mac's functionality and performance.

3. Activate the Optimize Storage Option on Your Mac

The Optimize Storage feature is one of the subtle yet amazing features that Mac supports but other PC haven't deployed effectively. Optimized Storage is an option permitting Mac to arrange and organize files optimally and automatically.

Apple Menu > About this Mac > Storage > Optimized Storage

Once this option is toggled on, it enforces Mac to automatically organize documents and clean unused, hidden or unread items, which can also transfer them to the iCloud, freeing up valuable space on your drive.

4. Decongest Your Mac Memory and CPU Space

A major reason for your slow Mac after its High Sierra update is that numerous applications are running simultaneously to consume vital CPU space so that the system slows down. When some applications run actively, others run in the background and also consume considerable space. To recover memory space and resolve this issue, we need to deploy the Activity Monitor.

Access Applications > Utilities > Activity Monitor

Under the CPU tab, you would see the distribution of CPU usage among the currently running processes. Should you identify an application that is not necessary but is consuming considerable memory space, be swift to eliminate it by tapping it and hitting the close button at the top-left corner of the screen. Unwanted apps can also be toggled off to save Memory.

5. Reconfigure SMC & PRAM/NVRAM

The System Management Controller (SMC) and parameter RAM (PRAM) are important tools in ensuring the smooth functioning of the Mac. Reconfiguring the SMC resolves all hardware management issues like fans or battery faults and so on. While reconfiguring the NVRAM handles issues like pertaining to booting, screen resolutions and battery charge, etc.

SMC on Mac Mini, iMac, Mac Pro & Xserve reconfiguration

  1. Power down your Mac and disconnect the cord
  2. Leave the system for 15 seconds minimum, then reconnect the power cord
  3. After a 5-second wait, power up the Mac normally

SMC on MacBook Pro, MacBook Air & MacBook reconfiguration

  1. Power down your Mac and disconnect the cord
  2. Leave the system for 15 seconds minimum, then reconnect the power cord
  3. Long Press Shift + Option + Control + Power button for 10 seconds minimum, power up the Mac normally after releasing all keys

PRAM/NVRAM reconfiguration on all Macs

  1. Power down the Mac, wait a few seconds
  2. Power up and simultaneously press Cmd + P + R + Option
  3. Release keys after hearing the restarting beep

Final Note

The slow Mac after High Sierra update is a widespread problem facing many users using different Mac models. However, the above manual solutios would cost you a great amount of time. Instead, the most effective one is Umate Mac Cleaner. It's an useful mac remover with just one-click, which greatly save your time with efficient cleanup. This app works amazing to speed up your Mac and you must be shocked by its powerful functions after using it.

Which Mac operating system is the best is a topic of numerous debates among Apple fans.

Run After Him! Mac OS

Since the mission of this blog is to refute myths and legends around Macs, it’s time for me to provide my 2 cents about the issue on hand. While everything below is just my opinion, as a long-time Mac user and veteran software engineer, I hope my opinion worth something.

The best Mac OS version is the one that your Mac is eligible to upgrade to. In 2021 it is macOS Big Sur. However, for users that need to run 32-bit apps on Mac, the best macOS is Mojave. Also, older Macs would benefit if upgraded at least to macOS Sierra for which Apple still releases security patches.

How to Tell Which macOS You Are Running

To find out which macOS is currently running on your Mac, follow these steps:

  1. Click on Apple logo in the top left corner of the menubar
  2. In the dropdown click on the first item: About This Mac
  3. The first line in the Overview tab is the name of the current OS.

What Version of OS Can My Mac Run?

Not all Macs can be upgraded to the latest OS version. For instance, old Macs powered by PowerPC CPUs cannot run OS intended for Intel-based computers. Also, some versions have hardware limitations.

For instance, Mojave cannot be installed on MacBook Pro earlier than Mid 2012 model.

Check below to know exactly what version of OS your Mac can run.

Which OS is Best for my Mac

Anytime someone asks me which OS is best for them I always suggested going with the latest. Things have changed recently, however.

Should I Upgrade to macOS Catalina or Big Sur?

While personally I like macOS Big Sur and have it installed on my MacBook Pro, it comes with serious breaking changes.

The first issue is compatibility.

Big Sur is a transition OS which is designed to help Apple to move from Intel processors to their own chips on ARM.

After I installed Big Sur on my MacBook Pro mid 2020 (pre-Silicon), most of my apps, including Microsoft Office, were working as expected.

However, my VMWare Fusion 11 does not start anymore, so I have to purchase a new license if I want to keep using it (or roll back to Catalina). Luckily, I took a full backup before the upgrade.

The second breaking issue is the lack of 32-bit app support.

macOS Catalina and Big Sur can only run 64-bit apps.

If you wondering whether you should upgrade to macOS Catalina or Big Sur, first verify that you don’t have any 32-bit apps. But first, take a back up, so you can go back in case something breaks after the upgrade.

For instance, I had to remove uTorrent after upgrade. And I didn’t know that uTorrent is 32-bit!

How to Know If App is 32-bit or 64-bit

To find out whether the app on your Mac is 32-bit or 64-bit follow these steps:

  1. Click on Apple logo in the top left corner of the Mac screen
  2. Click on About This Mac option
  3. Click on System Report button in Overview tab (first one)
  4. Scroll down to Software -> Applications
  5. Find the app and check Kind

Which macOS Should I Use

If you have an older Mac which is not eligible to upgrade with some latest software or hardware, I’d suggest upgrading at least to Sierra (or better High Sierra) for the following reasons:

  • Sierra is still supported by Apple, and it gets security updates
  • APFS file system is available
  • It supports Siri
  • Significant security improvements

The most important point when choosing the best OS is the ability to get security updates. While Apple generally does not announce the OS end of life dates, it is possible to know when they stop releasing security updates from this page.

For instance, according to the page, the last security update for OS X Yosemite was released on September 12, 2017. The last update for OS X El Capitan was in July 2018, and Carnegie Mellon University confirmed that El Capitan’s end of life date was August 2018.

Snow Leopard Myth

I know that some users on forums believe that the best OS version for Macs was Snow Leopard. But that is a myth. And I know how such myths get created.

Once I worked in the company, which was selling a 20-year old product. And customers were still using and didn’t want to switch to new versions, because the old one was rock solid.

I then talked to the engineer who worked on the project, and he revealed that the product was a total disaster when it was first deployed. Engineers had to work on-site for almost a year in order to fix all bugs.

After five or so years of polishing the product, it becomes virtually bug-free, and nobody now remembers how bad it was when it was first rolled out. A similar thing happened Snow Leopard, and it was recognized as best mac os version after some time.

How to Update to the Latest Version

There are two ways to update to the latest OS version on Mac:

  • From the Software Update section in System Preferences
  • Use a download link

Using Software Update

This is by far the best option, but it only available if you have Yosemite, or later OS installed already. If you enabled automatic updates, then Mac will inform you that the next macOS is available.

Just open System Preferences, go to Software Update and click on the Upgrade Now button.

This method is also best if wondering how to check if you have the latest version of OS installed on your Mac. Only the version compatible with your hardware will appear here.

For instance, my the latest version for Mac Mini 2012 is Mojave, I can’t install anything newer than that.

If you are having problems with updates or having issues post-upgrade check my post about troubleshooting macOS.

Using download links

For older systems or in case you need to downgrade, you have to download a standalone installer in DMG format. DMG stands for disk image, similar to ISO, just different formats.

After downloading the installer, just double click on it and follow instructions. Again, do not forget to take a backup before the upgrade.
