An iMac, MacBook or MacBook Pro is an investment. The price on these computers is typically double or even more than the price of a Windows computer running the same hardware specifications. So it only makes sense to spend a little on some upgrades as it ages rather than going out to buy the latest iMac or MacBook.
By doing some upgrades, you can extend the usable life of your iMac or MacBook for a few years. That is well worth the expense when you consider that the cost of upgrading is a fraction of the cost of buying a new computer from Apple.
Here are some upgrades that can make a significant difference in the speed and operation of your iMac or MacBook. Depending on your technical expertise, you may be able to do these on your own, but most users will require professional help.
Memory or RAM (Random Access Memory) is consumed when you open and run programs. Memory is a temporary holding area for all the work you are doing until you save that work back to the hard drive. When you run several programs simultaneously, it is easy to consume all of the available memory. When this happens, the hard drive has to be used for some of the temporary information. The hard drive is slower to read from and write to than memory so it slows your work down. That memory is not emptied or freed up until you close some programs or reboot the computer.
When you add more memory to your iMac, you essentially increase your temporary working space which allows you to open more programs and do more things without slowing down.
Solid State Hard Drive
All your programs, photos, videos and other files are stored on your hard drive. The MacBook or iMac is constantly reading from and writing to the drive. This is the biggest bottle neck in a computer's performance because hard drives are slow relative to the rest of the system. A typical hard drive has spinning platters, an electric motor and a moving arm that reads the data on the platters.
When you replace your hard drive with a new Solid State Drive or SSD, you drastically increase the speed of reading and writing files. Since the hard drive is where your files are stored, you will likely need help from an IT technician to duplicate your data from the old spinning hard drive to the new Solid State Drive.
Mavericks is the latest operating system from Apple. It has many new features like improved multi-monitor display options, improved battery life and faster email downloads just to name a few. You can install Mavericks from the App Store, but if you have an older MacBook or iMac, you may need to upgrade to Snow Leopard first and it may require a memory upgrade to install.
