Is it possible to upgrade an IMAC 10.4.11

I recently purchased an IMAC from a local high school upgrading their computers. It running on 10.4.11 and I cant find any antivirus's software that is compatable. Is it possible to just simply purchase the upgrade, or does anyone know a free antivirus that will support the older versions. Thanks.

iMac, Mac OS X (10.4.11)

You really shouldn't need any AV software, but if you feel you must then use ClamXav.

Hey thanks, I'm very new to Apple, and the learning curve is immense. Would it be worth upgrading the operating system?

Yes, depending on what your plans are for it. It's one of the very earliest Intel iMac models, so it has limited upgradability.


You can upgrade RAM from the 1 GB installed to 2 GBs. This requires replacing the two installed modules with two 1 GB modules:


Maximum Memory2.0 GB
Memory Slots2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM


I recommend OWC or DataMem as memory sources.


You can upgrade the OS as far as Lion, but I would recommend going just to Snow Leopard. It will be better with that older hardware, plus you will be able to run older PPC-only software:


Upgrading to Snow Leopard


You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.


After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.


Snow Leopard General Requirements


1. Mac computer with an Intel processor

2. 1GB of memory

3. 5GB of available disk space

4. DVD drive for installation

5. Some features require a compatible Internet service provider;

fees may apply.

6. Some features require Apple’s iCloud services; fees and


terms apply.

At the present time there are no viruses affecting OS X. There have been some trojans skipping about, but if you upgrade to Snow Leopard 10.6.8 and the security updates and Java updates, you will be protected by the Apple software. Most trojan protection is in between the ears. Avoiding the temptation to click on links you know nothing about or replying to spam email. Also, see:

An excellent link to read is Tom Reed's Mac Malware Guide.

Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.

If you require anti-virus protection I recommend using ClamXav.
