The life of technological devices is short, it is something that anyone knows very well. Despite the fact that Apple computers are well supported by the company, with official updates for several years and with quite acceptable performance, in older models the passing of the years is inevitable, and when one begins to demand more advanced tasks, it shows.
This is the case of my MacBook Unibody Late 2009, upgraded to OS X Yosemite with good performance, but that is already five years behind. With the RAM memory expanded to 4GB, one more step to improve its performance was change your conventional hard drive for an SSD, with a much higher data transfer speed and lower energy consumption, aspects that both the battery and the performance of the computer would appreciate. We show you in video how to carry out the whole process so that you can do it yourself.
As you can see in the video it is about a very simple procedure, and with the necessary tools (just a screwdriver with Philips and Torx bits) you can do it in just a few minutes. When it comes to choosing your hard drive, the options are many. With this MacBook model I can't benefit from the speed of a SATA-III, but the price difference with a SATA-II is minimal, so I opted for the model first. Regarding the capacity, I opted to keep the same as my laptop was standard. In short, I found in amazon the SSD that was perfectly suited to what I was looking for in performance, capacity and price.
Once the hard drive has been changed we only need a USB memory previously created with the installer of our operating system. In SoydeMac you have a fabulous tutoring of how to create this USB stick with OS X Yosemite. We turn on our MacBook with the new hard drive and the USB connected, and we press the Alt key during startup. As seen at the end of the video, our installer will appear on the screen and by pressing Enter we will access the installation program. Once inside the installation program, we must form the newly installed hard disk with Mac OS Plus format (with registry) and GUID partition table. Once the formatting is done, we can install OS X Yosemite without problems.
Another alternative is to first connect the SSD to USB with a SATA-III to USB cable. and install the operating system, so once the hard drive is changed we can directly start our system without problems. So we can have the peace of mind that everything is in perfect condition before removing our old hard drive or putting in the new one.
If you are not yet ready to jump to the SSD or change the hard drive for a higher capacity one but you suffer from the problem of «startup disk full on Mac«, In the link that we have just left you we give you solutions to free up space since it is a factor that will also give some fluidity to the system.
