How to speed up slow Mac for free?


No matter how fast your Mac is the moment you unbox it, eventually, it will slow down if you do not manage your files or other items including media in an organized manner. Albeit, things have improved over the time with blazing fast disk drives. There is still a lot of room for improvement as far as file management is concerned.

Mere unprofessional file management is not the only culprit. There are other factors including unoptimized system memory, unused Apps hogging system resources on your Mac, unwanted login items throttling boot speed that stifles a cleaner or faster post boot experience.

So, how to deal with it while enjoying your Mac? How to speed up your slow Mac for more productivity in less time? One easy tool to manage all this in a single package for your Mac is to use Stellar SpeedUp Mac. More on it later in the post, let us first look into basics of why your Mac might be running slow, also, whether macOS packs any built-in tools to make your Mac run faster.

Why is your Mac running slow? What are the generic or built-in tools to Speed up your slow Mac?

According to Apple, there are could be a couple of reasons why your Mac is runs slowly:

1. Your primary disk might not have enough free storage space.

Your Mac’s startup disk might be running out of space required for more files that new and current Apps to run to obtain desired performance. You have to move some less important or less used files to external storage, including USB drives and Flash memory cards.

You can easily use built-in Finder App to move files to or from an external storage device. It offers you an easy way to connect and eject external storage from your Mac for proficient two-way transfer of big data or large files. This method can similar be used for media types like photos and videos, which can also be worked upon while being on external storage devices. Some external connecting ports like Thunderbolt and USB-C (USB 4) can achieve as good as native read and write speeds on external storage drives.

Other than more conventional method of moving files elsewhere, macOS also happen to offer us with a more organized set of recommendations based on your usage to organize storage space on your Mac.

Among these recommendations, first comes Apple’s own cloud storage solution that is tightly embedded into macOS called iCloud. You can move various file types and items to it to free space on your Mac. It works flawlessly with most of the applications designed for macOS. It also adds up as a solution for file redundancy or a backup solution for every item or files you move to iCloud.

You can also optimize storage by automatically removing Apple TV content like movies and TV shows that are already watched, and also by simple things like keeping only recent email attachments when space is needed by other Apps. You can also set your Mac to Empty Trash Automatically to reduce clutter but if it is not enough, Apple’s macOS has designed a tool to ‘Reduce Clutter’ from your Mac literally.

It helps you find and review files to let you delete them manually if no longer required.

2. An app you’re using may require more system memory than available on your Mac

Although macOS is known to have better system memory management in general, there is no denying to the fact that modern Apps require more resources, especially RAM. If you happen to use Apps that happen to feast on system memory, you should consider adding more RAM to your Mac, which might not be available with modern M1 based Macs with unified memory on chip. It is suggested that you get enough RAM for your portable non-user upgradable M1 Macs right during the purchase, so you do not end up with less system memory down the line.

For other Macs, you should upgrade your RAM to official recommendation by software publisher or developers to get the best performance out of your Mac.

3. Quit or Uninstall Apps that aren’t compatible with your Mac or you are not using on daily basis

Do not keep Apps that you are not using at all. You should also disable login items, so they do not reopen when you restart your Mac. Apple has some tips on how to quit Apps on Mac. There are also some Apps that might not be compatible with your Mac, taking unnecessary resources, making your Mac slower over time. You should completely uninstall such Apps and download compatible versions. For instance, you should get native version of Apps for your Apple M1 Silicon instead of using an App that uses automatic translation of an app for use with Apple Silicon if available to save on vital resources spent on translation.

4. Use Disk Utility to Repair a disk

You happen to have abrupt things like crashing or closing of multiple apps or corrupt files or inoperable external drive or start-up / boot related issues with your Mac, you better use built-in Disk Utility to verify and fix disk issues, if any.

Disk Utility can check for and fix errors related to the formatting and directory structure of a Mac storage device.

You should use built-in Disk Utility to run First Aid on your primary storage. Once the check is complete, the Disk Utility tells you to back up your data in case of a failing irreparable disk.

5. Open Activity Monitor when things go south

When you see sudden mismanagement of system memory or performance hit owing to unusual use of processing power on your Mac. It is always advised to check that App or service is causing it. It might be an application or a game that you have downloaded yesterday or something that just got an unstable update.

You can easily figure out the cause of the sudden change on your Mac with simple and easy to use built-in Activity Monitor.
