Like all computers you will notice your Mac will start to slow down a bit after a few years but before you go buying a whole new unit you can replace the old hard drive with a new solid state drive also known as a SSD. This is any easy process on the MacBook and your iMac but a little challenging for a Mac mini. In doing this it can boost the speed yielding 3X to 5X. The other option is to upgrade the Mac’s RAM.
This is a cheap and easy option if your Apple Mac isn’t too old but you just don’t have a lot of room left. Installing RAM doesn’t generally void your Mac’s warranty with exception of some models.
Random Access Memory (RAM) is a small replaceable circuit board full of memory chips this is designed to give your computer a high-speed temporary workspace. This is where the apps and data are stored while you are actively using them. It helps your Mac run bigger apps and several apps at the same time, it reduces and eliminates the need to continuously load data from your hard disk or SSD. It is recommended with the new Yosemite to have at least 8GB of RAM if not more.
To swap your RAM you need a small screwdriver to open the panel. To release the current RAM in the Mac you push down on the clips releasing the RAM boards, then place the new RAM boards into place. Most Apple Macs have two RAM slots, which is usually half the RAM in one slot and the other half in the second slot. iMacs and Mac pro’s typically have four slots, the iMac uses high-quality but consumer-grade RAM, the Mac Pro typically uses some of the most expensive RAM available and the base model currently ships with 12GB of RAM already installed. It is not recommended to put cheap RAM into your Mac as it can cause all sorts of problems such as your Mac crashing and failing. You can replace the RAM boards separately but it is wise to replace both of them at the same time, just like when you change batteries you change them all at the same time. It’s just for safety so you don’t upset your Mac.
This is the best way to speed up your Mac and give it more life. If this doesn’t do what you need it to do then maybe you need to look into installing a SSD but this is recommend to be done by a experienced technician.
