Product Description:

This small command-line utility thoroughly checks available memory under OS X. Memtest is licensed under the Gnu Public License and is distributed with source code. This program is authored by Charles Cazabon and the OS X port is maintained and enhanced by me.

What's new in this version:

Version 4.04M is based on memtester 4.0.4 which Charles released late in August. New to version 4.04M is the ability to run Memtest in single-user mode and improved execution speed of the individual tests. Running in single-user mode frees up the maximum amount of available memory for testing and is an enhancement that I've wanted to do for some time. Version 4.04M replaces version 4.03M and improves the reliability of operation in single-user mode compared to that of 4.03M as well as incorporating minor additions made by Charles to his Linux version 4.0.4. Many thanks to Charles for his efforts to improve cross-platform compatibility of the memtester source code, making it possible for me to deliver single-user mode operation for MacOS X.

Operating System Requirements:

This product is designed to run on the following operating systems:

Mac OS X 10.3
Mac OS X 10.2

Additional Requirements:

Mac OS X 10.2 (Jaguar) or higher

Rember uses memtest at its core. However, Rember isn't able to test any memory that is being eaten by the OS, so, if you want to really test your RAM, you should:

1) install Rember

2) Boot into single-user mode:

hold command-S on boot, then:

/sbin/fsck -fy

/sbin/mount -uw /

3) Once you have the hard drive mounted, run the memtest executable buried in Rember. If you installed Rember to /Applcation/Utilities the path would be:

/Applications/Utilities/Rember.app/Contents/Resources/memtest

For memtest switches look here:

It's one thing to charge for the software, but as I understand it, this is open source software that he's modified, so any changes he makes to it are required to me made open source as well. By putting it behind a locked door (i.e. you don't get the source until you pay for it) he's breaking the license, last I checked.

The developer could charge a higher fee, and automatically email the latest revision the way SoftRAID does. That should address his concerns and not be a hassle for users wanting the latest version.
