Slow Mac computer performance is not something that just erupted. It is rather a gradual process. Generally speaking, a Mac computer is a PC (Personal Computer) and its performance degrades over time.

As for example, when you have your new Mac, even the battery seems to last for longer hours. When you compare the length of the battery performance of the same Mac after six months, you can then find it cut by half. This is a performance degradation. This applies to many hardware components. Also applies to software and applications since they may have bugs.

Really a slow Mac?

The questions is: whether your Mac is really slow? The main causing factor behind the slow Mac performance is the performance of its drive, memory and other hardware components. Said that the operating system is flawless, the hardware must be in a good health to output better performance.

The performance of a computer is an output of the collaboration of software and hardware. Anyone of these inherits issues, the performance of the machine is directly proportional to it. When the operating system and applications are in an excellent collaboration, the computing performance is admirable.

What is the culprit of a slow Mac?

It is by now apparent that Engineers design the capacitors and transistors to have certain life cycles. Once it reaches the life cycles, it tends to fail. Before it fails, it begins to render issues which we would like to call a component malfunction. This actually helps the manufacturers redesign and bring upgraded versions of the device in the market each year. On one side, this is sad that a computer like Mac is meant to die after certain years. On the other side, this trend offers flexibility to bring in more powerful and efficient computers.

Is there a way to make a slow Mac fast?

Eventhough there are several refreshed and upgraded models of Mac introduced in the market each year, it does not mean that you have to keep buying them. There are ways that help you speed boost your existing Mac and keep it for several years. This is possible when you see that your Mac is really becoming a slow computer. If a Mac is slow, its hardware is failing. It can also be that the applications on it are having issues. This also triggers an alert that the operating system is failing.

As discussed earlier, computer performance is directly proportional to the collaboration of its hardware and software. You need to make sure which one of these is the causing factor. You can notice such by visiting Activity Monitor. You can see the processor performance, available memory or the behavior of the running application. You can also monitor the errors your computer is having by launching Console. These are primary sectors that are quite capable to show you what your machine is doing and how it is doing.

How reliable it is to service a slow Mac?

Most of the hardware technicians suggest that you approach a service shop once a year eventhough your Mac computer is not slow. Why? The reason is simple: to give it a nice cleaning. The service tech would inspect your Mac and if did not find any operating system flaw, memory issue, drive issue or hardware issue, would recommend to go for a device cleaning.

Such service would open up all clogged physical ports, clean the vents, blow out the dusts and debris from fan(s) and keyboard. This service is of a low cost profile but comes with the highest value possible. A comprehensive cleaning of your computer saves CPU and GPU from failing before its life cycle ends. And even may help lengthen its life cycle.

Is there a hardware based attempt to fix a slow Mac?

There is. There is a complex method to fix a slowness of a Mac and bring it back to the factory default speed. This is a risky attempt but worth applying. Only an experienced technician should attempt this procedure. Many of the hardware technicians know this process as a reflow. Reflow is a process of extreme but measured and monitored heat, the maximum heat that a process or a graphics processor can tolerate. This process melts the silicon of the processor and brings it back to its original spot if it is microscopically flowed and creating exhaustion by almost touching the neighboring room. When done precisely, it revitalizes the stone to work the way it was first designed to work. You will see an enhanced and reliable performance.

There is also a way to restructure or recover damaged directories from a given drive. This would speed boost the drive performance. You can also speed boost by transforming the conventional platter related drive to a Solid State Drive (SSD). Such attempt will have a visible speed boost. You can also double the default maximum supported memory which will significantly enhance the operational efficiency of your Mac. And, there is a significant way to do nothing but reformat the drive and reinstall the most reliable operating system your Mac is meant to work best. This will give you a surprise in performance in many instances. Consult a Mac technician to see which operating system is the best one to work the best way possible in your Mac in hand.


Regardless of the slowness of a Mac, there is always a way to make it faster, perform better and get the best out of it. If you consider using your Mac for a few years more to go, do yourself a favor and visit a service shop to give it a nice cleanup. You may schedule an appointment if you need such services.
