In the email the company says "Apple has released a significant update to Leopard, version 10.5.3, and in turn we have created a scripted installer which will allow Open Computing users to perform this update while ensuring that your computer remains fully functional." They go on to warn that "you should not download this update directly from the Apple website as it may cause your system to become inoperable." (emphasis mine.)
Please read the following and make note of it because it will be important when you update your Open Computing product:
- You must have your retail copy Mac OS X Leopard CD in the CD-ROM drive to be able to install this update
- This update will require you to restart your computer once it is complete
- Although the scripted installation is a little over 1MB, the 10.5.3 update from Apple is a very large (over 500MB) download that may take a very long time to download depending on the speed of your internet connection. The scripted installer will download it for you during the installation process
- You must select the appropriate model of computer (Open or OpenPro) and the appropriate model video card when prompted or else your machine may not have video upon reboot
- After the installation is complete and the machine restarts the machine will enter the Apple loading screen for approximately 5 minutes and then reboot (although this process may take longer). Once the machine reboots again it will return to a normal functioning state. It is imperative that you do not reboot the machine prematurely. Rebooting the machine early may cause undesirable effects including, but not limited to: broken operating system.
