The Story of your Certified Pre-Owned Mac
The Certified Pre-Owned Macintosh computer you buy from GainSaver has been fully tested and certified by GainSaver's trained Apple technicians to verify every major component is in 100% working order. Our Certified Pre-Owned Macs come ready for you to boot up and use with Apple OS X Tiger and Apple iLife installed.
The first step is receiving thousands of pre-owned Macintosh computers every month, mostly from corporate and academic environments. GainSaver purchases Apple systems in large lots with quantity discounts. That's how we can offer such a huge selection at the lowest prices anywhere. Once we have these great bargains on the shelf in our warehouse, we get to work adding value for you.
Our primary concern at GainSaver is to make sure you get a fully functioning Macintosh that gives you years of exceptional service. So the next thing we do is take apart every unit that comes in. GainSaver technicians remove each component for individual inspection. The hard drive, optical drive and memory are all tested separately outside the computer. Then the motherboard is tested, and in the case of notebook computers, the keyboard, touch pad and screen.
Next the hard drive is reformatted, removing any trace of what the last owner had installed on the system. The process also verifies hard drive functionality and ensures the drive has no bad sectors. Then Apple OS X 10.4 Tiger and iLife are installed, so you have everything you need to use your Mac, including browser, desktop search, chat and video capabilities.
Apple iLife is a suite of applications, which includes all these powerful tools:
for managing and enhancing your digital images
for creating digital films
for burning your DVDs and CDs
to create your own musical compositions
for building your own website
Then we put it all together.
Once all components are checked, the unit is reassembled and tested one final time. At this point, we can guarantee the Macintosh you buy is working flawlessly, and mark it Certified Pre-Owned for your protection.
GainSaver Macs are Certified Pre-Owned. We're here to help. Call or click now!
How to customize your Mac with the Macintosh Configurator
When you buy a Certified Pre-Owned Macintosh from GainSaver, you get exactly what you want. No more and no less. Every order is customized to your needs with the Macintosh Configurator at the top of the page. Just select the configuration options you want from the Configurator's menus. When you're done, click the Buy Now button. Below are some things to consider when you make your selections.

The hard drive is where all of your programs, documents, songs, images and videos are stored. Hard drive sizes are measured in gigabytes, so "250GB" means the hard drive has 250 gigabytes. One gigabyte of storage can hold about 10 music CDs. That's about 250 songs in MP3 format which can be played on your iPod. A DVD movie takes up a lot of hard drive space, anywhere from 5 to 10GB. Mac OS X 10.4 Tiger and iLife takes up about 11GB of Hard Drive Space.
Basically, the more hard drive space you have, the better. People hate to delete things they have collected, like favorite songs and family pictures. So you should get a bit more than you think you are going to really need. New Apple Macs come standard with up to 250GB hard drives. They keep getting bigger every year because people are always installing more programs and downloading more and more files. Plan ahead and get at least 160GB.
You should get even bigger than this if you are doing any image processing, video or music production with your Mac. In that case the 500GB is recommended. And remember: your Mac will come with Apple iLife, so you'll have the tools you need to make videos, do image processing and other tasks that use a lot of hard drive space.
Optical drives play CDs and DVDs. Apple has two kinds of optical drives, the SuperDrive and the Combo drive.
The Combo drive came first. It was a big advance over the CD drive, which played and recorded on CDs only.
The Combo drive also plays DVDs. You can watch DVD movies on your Mac with a Combo drive, but you cannot record on DVDs, only on CDs. Recording on DVDs requires the SuperDrive.
The SuperDrive does it all: play and record on CDs and DVDs. Writing on DVDs is a great benefit, because you can store up to 4.7GB of data on one single-sided DVD disc. This is about 8 times more than you can store on a single CD. This makes DVDs perfect for inexpensive backup of your entire hard drive, or at least your critical documents, songs and family pictures.
Selecting the right amount of memory for your needs is one of the most important decisions when you customize your pre-owned Mac. Memory is different from hard drive space, which is for permanent storage of your files and data. The Mac can't do anything with that data until it is actually transferred from the hard drive into memory. Hard drive data is sort of like information in a book. You can't think about it until you've read it into your own memory.
Computer memory is measured in megabytes and gigabytes. The best amount for you depends on the programs you plan to use, and how many programs you are going to run at the same time. Mac OS X v10.4 Tiger comes preinstalled on all pre-owned Macs from GainSaver. The minimum requirements are 256MB of memory. However, this is the bare minimum. With only 256MB of memory what happens is that the operating system and the programs you run have to keep saving to the hard drive and swapping data back and forth between memory and the hard drive in order to run. This is like your Mac having a short term memory. It has to keep looking things up on the hard drive, and this really slows things down.
The same thing happens again if your programs or data files become bigger than what can be handled in memory at the same time. So the way to get the best performance is to get as much memory as you can. You should always get at least 512MB. If you are creating graphics and doing image processing, then you should get 1GB minimum. And if you are working with real time audio and video production, get the max your Mac can support.
Wireless Apple Card
You'll want to keep your Mac connected to the internet. The fastest, easiest way to do that is with Apple's Airport Extreme Card (or Airport Card for older Macs). The Airport Extreme Card is the standard for connecting wirelessly. More and more public places such as schools, office buildings and even coffee shops offer free Wi-Fi access to the internet. All you need is the Airport Card to take advantage of it. You can also exchange files with other nearby Macs that have Airport capability, play multi-player games or even do some serious work. And because the signal travels through walls, you don't even need to be in the same room.
Make sure to add the Airport Extreme Card (or Airport Card) with the Mac Configurator. The alternative is being anchored to your desk with an ethernet cable.

What about scratches?
This is an important issue to some people. GainSaver technicians can fix just about everything but the minor dings and scratches. If some blemishes on the exterior are a problem, you may want to consider spending more and buying a new Mac.
Most people don't mind the scratches. We have customers who order Power Macs with a dented case and think about just how much they saved every time they see the dent. Some can tolerate just a few marks and scratches, and finally there's the group that prefers to buy their Certified Pre-Owned PowerMacs in a brand-new-from-the-factory case.
The important thing is that you are not surprised. Expect some dings and scratches. But because these are Certified Pre-Owned from GainSaver, you know they are guaranteed to perform as advertised.
Save the smart way with Pre-Owned!Don't worry!
If you are not totally satisfied for any reason, you can return the system to GainSaver for exchange or full store credit. We are happy to work with you to make sure you get the computer you want at the price you want. For personal service give us a try. Call Now: 800-844-4051
GainSaver technicians test every component of each Mac before it is shipped out. However, there are certain problems that can only be uncovered through extended diagnostics testing over a period of 24 hours. Some hardware problems don't appear until the computer has been turned on and running for at least a few hours. This is especially true of the mother board, ports and LCD screen in Macs that include a screen.
Diagnostics Testing is done after final assembly of your custom configured Mac. Software programs put the computer through a battery of tests and monitor performance. The test results are analyzed and any necessary changes are made.
The Macintosh is famous for its ruggedness. Millions of older Macs are still in operation and still supported by Apple's application and system software programs. That's the whole point of getting a Certified Pre-Owned Mac from GainSaver. You want to use it as long as possible.
A Mac is not like most electronic devices you buy and end up never using. Six months later they are in a drawer somewhere. But you know you will use your Mac every day, and you will use it until it stops working. At that point it will need to be replaced. With this in mind, you should consider GainSaver's Extended Warranty protection. You can purchase additional coverage for 90 days, or 1, 2 or 3 years.
The GainSaver warranty is the best anywhere, even better than Apple's own warranty on new Macs. The GainSaver Extended Warranty covers any and all damage that occurs through normal use. Every hardware component is included, from hard drive to memory to keyboard to screen. The coverage is even transferable if you sell it to someone else during the warranty period. This type of protection is not available anywhere. It's a big reason why people choose GainSaver and keep coming back for Certified Pre-Owned Macs they can count on for years of service.
GainSaver offers shipping insurance to save you time and money in the event of delivery problems.
We use FedEx exclusively to make sure your Mac arrives in one piece. But accidents can happen. And when they do, it can take a while for claims to be put in and repairs made to your computer. When you add GainSaver insurance, we will repair or replace your equipment free of charge in the event of damage during shipping.
Select Insurance from the Configurator if you really need your Mac right now, no matter what happens.
