Will upgrading my ram/memory void my Apple Warranty?

No, it won't void your warranty. Apple considers ram to be a "user-installable upgrade". So, you can install ram without voiding your warranty. Refer to the Apple Support Article for more information on this.

How long will it take for my ram to arrive?

Please refer to Shipping & Returns for more info.

How do I install the ram?

Unfortunately, there is no "one size fits all" answer to this question. Every Mac model has a different installation process. The good news is that the Apple Support website has detailed installation instructions for just about every Mac. So you will have step by step info to help you (usually it takes about 3-5 minutes to install ram)

We have compiled a list of the most common mac memory installation instructions. If you don't find the mac memory installation guide you are looking for, try searching on the Apple Support website for "How to install memory ".

What is your refund policy?

You are covered by our two pronged guarantee:
1. A lifetime warranty on the ram itself.
2. Compatibility with the Mac we recommended the ram for - so even if the ram is OK, but it doesn't work with the mac we stated it would work with, then we will replace it (though there may be a cost difference between different types of ram - and that will need to be paid if the ram is replaced with more expensive ram).

If you change your mind, you can return or we can replace the ram for a $25 restocking fee, plus postage and any price difference in the ram.

Send us an email letting us know what the problem is. If covered by our Guarantee, we will then send a Return Authorisation form. Send the ram back to the specified address within 7 days, and we will issue a replacement.

MacRam: Ram for Macs is owned by Mayhem Two Pty Ltd, and Adelaide-based company. Our ABN is: 32 083 044 786. We are 100% Australian owned and we buy our ram from Australian based suppliers.
