OS X is responsible for memory management (unloading RAM and disk cache contents), and proper memory management is crucial in ensuring your machine is running smoothly. OS X does a quite decent job of memory management, but it’s not perfect.
Sometimes the RAM and disk caches are not emptied properly, even though they were supposed to (like when you quit a running program), and this can lead to issues. To remedy this, you can force your Mac to clear out the RAM and disk caches without rebooting, which can be very useful if you want to give your system performance a “boost” without restarting.
To free this space and make available more memory for the system, you can use a simple command in your Terminal. After opening it, type “sudo purge” to remove all the unused files from the RAM. It will ask you the administrator password to run this command, enter it when the prompt asks for the insertion. Thats it, you will feel the your MAC is as new as a reboot.
Day by day, your MacBook will store some information in the system cache such as system logs or big file cache for a faster startup, but in the long term, they become useless and only take space in the hard drive. To free some space in memory, you can access the folder that contains all these files and delete them:
Enter in the Finder
You can quickly access the folder pressing the Command + Shift + G combination and copy/pasting the path.
This will help you free up lot of space by deleting junk.
Dozer is a simple application that lets you hide menu bar icons that you may not need all the time. The program has the ability to keep a few icons visible while hiding the unnecessary ones. Once you have hidden your menu bar apps, only the tiny dot icon will be visible. However, you can reveal the hidden icons easily, with just one click on the desired icon.
You can download it from https://github.com/Mortennn/Dozer/releases/tag/v4.0.0
Note: Key combination to move menu items are Command + Drag (using mouse).
MenuMeters is a set of CPU, memory, disk, and network monitoring tools for Mac OS X. Although there are numerous other programs which do the same thing, none had quite the feature set I was looking for. Most were windows that sat in a corner or on the desktop, which are inevitably obscured by document windows on a PowerBook’s small screen. Those monitors which used the menubar mostly used the NSStatusItem API, which has the annoying tendency to totally reorder my menubar on every login.
The MenuMeters monitors are true SystemUIServer plugins (also known as Menu Extras). This means they can be reordered using command-drag and remember their positions in the menubar across logins and restarts.
MenuMeters is open source freeware released under the GNU General Public License version 2.

One of the big questions in the mac community is that should I upgrade to mac os 11 Big Sur? The biggest fear was about the current status of Mac os Catalina which has many issues and bugs.
So what made me jump for the beta was a basic problem I was facing. As we all are using more and more things on the web, the most important app for any of us now is the browser.
So what got me interested was the promise of the better battery life and claim of 50% faster website load times by using the safari browser available with Big Sur.
So I took the risk and upgraded to a beta version of Big Sur. And I am glad to inform you that it works right out of the box. The new look and feel are debatable, but I don’t mind the new look. The best part is it is snappy and it has converted my old mac 2017 to a new mac. There are hardly any bugs and the system is stable and fast. Safari browser has also not disappointed me. It is fast and optimizes to take less processing power and battery power. I am happy that I took the risk and really enjoying the new OS and if you can you should upgrade it too. Let me know your suggestions

Overheating has become a common issue with Macs. Actually, believe it or not, thanks to Chrome, your mac may even be overheating when you are just BROWSING the web. Having an overheated Mac isn’t just uncomfortable to use, but as someone who likes to take full advantage of his technology, an utter waste of precious dollars spent. When the CPU reaches a temperature high enough, it will do anything to cool down the computer, which means slashing down your CPU’s performance.
Apple’s stubbornness to increase the speed of them. At times I’ve seen my Macbook go to upwards of 55 celsius and yet the fans are barely turned up and heard.
A simple yet very effective way to solve 90% of this problem is to simply turn up the fans manually. I would recommend maxing out your fans before doing something heavy, and leave the fans on until you are done with the task. I recommend using MacFanControl for this. Their service is completely free without ads, and I have been started using them now.
Install it today from https://crystalidea.com/macs-fan-control and see the difference.
