Owning a Mac, I find I have to do very little maintenance to my machine. It runs well majority of the time and only slows down when I have had it on for weeks or have 15 applications opened at once. However, I still find it important to monitor my computer to make sure it’s running at an optimal level. These are the tools I use to monitor and maintain my computer.

 

iStat Pro

iStat Pro is a free widget that is installed into your dashboard. It helps monitor your system so you know what is happening on your computer. The features include:

  • CPU usage – to monitor how much your processor is being used as a percentage.
  • Memory usage – this is great as it can usually help you determine why your computer is running slowly. If the graph is completely blocked out in a single colour, it means you need to reset your computer to free up some memory, or use FreeMemory (see below) to help you out with that one.
  • Disk Capacity – you can see how much space you have used and how much space you have free for any disk you have attached such as your computers hard drive, an external hard drive, a network drive, a USB drive, etc. I try to make sure I stay under 80-85% capacity on any drive I use to help prevent crashes and keep my computer running fast. Whenever a drive gets full, it significantly decreases it’s speed.
  • Temperatures – you can monitor the temperature of any part of your computer. If you have your laptop on a soft surface, it may block the fans at the back of the computer and make the computer very hot. This is not good for the computer so this section allows you to monitor the heat of any part of your computer and act accordingly.
  • Fans – I don’t monitor this section very much, but this can also help you understand why your computer is loud or heating up.
  • Battery – this helps you determine your battery health (how much of the original capacity of your battery that it can now be charged to), cycles (how many times your battery has been charged when it has reached below 50% capacity), charge percentage and remaining time before it’s empty. To keep your battery healthy, make sure you fully charge it, then fully drain till it shuts down and full charge it again at least once a month. I set a pop up reminder in iCal and have it pop up once a month to remind me to do this.
  • Uptime – this is one section I use a lot. I rarely turn my computer off (looking at my uptime now it’s up to 22 days), because I usually just close my laptops lid to put it to sleep. This allows me to start up my computer quickly from it’s sleep and my machine seems to run well doing this. However, when my computer is running slow, chances are it’s because it has been on for too long. To correct this problem I have to restart my machine to free up some memory and make my machine run fast again.
  • Processes – these are the applications that are running and how much CPU power or memory they are consuming. You can see what applications are really stretching your computers performance or see whether all of those applications being open at once really effect your machine.

I find iStat Pro invaluable for monitoring my computers performance. A quick peak at it usually tells me why my computer is not performing at it’s optimal level and I can act accordingly.

 

FreeMemory

FreeMemory is a free Mac OSX app store download. That means it can be accessed from the app store that is on your Mac desktop or Mac laptop. This is not to be confused with the iTunes app store. The OSX app store helps you download a range of software to your computer, even iWorks (Pages, Keynote, Numbers) can be downloaded in the OSX app store so it’s very convenient. However, the apps are generally fairly expensive. FreeMemory is one exception to this rule. It works the same as the memory usage section of iStat Pro but it displays your memory usage in your menu bar all the time. So if your computer is running slow, a quick glance to your menu bar can help determine the problem. The app also helps you clear memory, but that feature takes a long time to complete. To clear the memory fast and more effectively just restart your computer. But for monitoring your memory usage in real time, it works great.

 

 

Broom

Broom is a great app from the same makers of FreeMemory that allows your find and delete large files on your computer. It only cost 99 cents US and is a cinch to use. It helps you locate files in three sections, Places, Folders and Files. The Places section is handy because it searches your caches, logs, trash and downloads folder and tells you how much space each of these sections are taking up. You’d be surprised how many files end up in the caches and logs sections! To delete them, just select the section you want to delete and click the ‘Remove Selected’ button at the bottom of the app, couldn’t be easier!

In the Files and Folders sections, it makes a list of all of the files and folders on your computer and how big they are, so you can sort them by size order and see which files are really taking up a lot of space.

 

These are just some of the tools I use regularly to maintain and monitor my machine. Do you also use these tools? Are there any that you use regularly? Leave a comment below with your thoughts.
