I have an old 20 inch iMac from 2008. It is a 2.66 GHz Intel Core 2 Duo with 4 GB of Ram. Its still running Leopard 10.5.8, which is te last version of Leopard (I believe).
I have several questions, but I will start with the biggest one.
How can I speed it up? It runs very sluggishly and I've tried just about everything to try to get it to speed up. I've done all the recommended things, such as removing unnecessary startup programs, repairing disk permissions, freeing up hard drive space, monitoring the task manager for processes that take up a lot of CPU power and I've added more ram. The CPU can be at 90% idle and it will still act slow.
I know its not the software because its as old as the OS, so the system should be able to handle it, for example, I am running Adobe CS3. A friend told me that maybe I need to defragment. I read that after a certain OSX version the system does not need to defrag because the OS prevents the hard drive from fragmenting in the first place. Plus, there is no utility to defrag in the OS. I also read somewhere that if you do happen to fill up your hard drive to the very brim the data will fragment regardless. I did fill the hard drive to the brim -- to about 500 MB of free space. Since then I have freed up about 100 GB, but its slow.
Should I find a way to defragment? If so, is there any 3rd party software that is recomended for an old system like this?
I have tons more questions, such as:
- How to upgrade the OS to Snow Leopard, Lion or Mountain Lion.
- Should I backup the system via Time Machine before upgrading the OS to Snow Leopard, Lion or Mountain Lion?
- If I do upgrade my OS will my software be incompatible and do I need the original software discs to reinstall them?
- Why does my Time Machine take so long to backup?
I'd like to start with an answer about defragmenting.
