Over time, memory requirements tend to go up, so OS X 10.7 needs 2GB in order to run. Every application you open needs more memory of its own, and the more complex the app, the more memory it needs. Lower and mid-range Macs came with 1GB of RAM for a long time, but this is the minimum needed just to run OS X 10.5 or 10.6. So users of older machines tend to see the spinning beachball a lot as iPhoto thinks about processing a picture or Safari struggles to load a webpage. Your Mac holds information in RAM while it works with it and if there's not enough, it uses the hard drive for virtual memory, which is slower.

Memory is probably the number-one cause in slowdowns and poor performance, not least because it tends to go hand in hand with a full or failing hard drive. The result is that Macs that are a few years old (especially lower end Macs), tend to have too little RAM installed if they have never been modified. RAM for Macs used to be expensive, and Apple is in the business of making money. Ironically, this was at a time when Macs were, relatively speaking, more expensive than they are now. With a little care and attention, as well as an understanding of what can make your Mac slow down, you can spend less time waiting for the spinning beach ball to disappear, leaving your Mac to give you years of faithful service.įor many years, Apple sold most of its Macs with less RAM than they really needed.
This stuff isn't rocket science, it just involves knowing that music and photo libraries can get huge but can also be moved, or that after a year or two your browser's cache gets clogged up.

The same applies to upgrading to a newer version of Mac OS X and swapping an old, creaking hard drive for a new fast one or even a solid-state drive.Īnd for all Macs, even the latest ones, exercising good file management and housekeeping is important for keeping things running smoothly. Filling your Mac with as much memory as it can take is like getting a new computer. The most common causes of slowdowns in older hardware are full hard drives and insufficient RAM. The point is a five-year-old MacBook is quite capable of doing everything the average user needs. Thanks to Apple's desire to help us get on with iOS devices, the latest iTunes will run on a G4, provided you have OS X 10.5 installed (even if some features, such as HD video playback, will be unavailable).
