Micromat has been creating diagnostic software for both novices and professionals to test and repair Macs for 27 years. MacCheck builds on this experience so that you can get a clear picture of your Mac's health.
MacCheck does basic a basic evaluation of your Mac - scanning some common problem areas, including system errors, memory and internal hard drives. For more advanced testing, consider TechTool Pro for a more thorough and comprehensive testing solution.
Power On Self-Test - The Power On Self-Test (POST) is an automatic test that is run by your Mac's hardware each time your Mac powers up, before Mac OS X is loaded. POST checks the basic functioning of RAM, Processor and boot ROM.
Battery Test — Laptop batteries can be charged a large but finite number of times, or charge cycles. Once the battery has exceeded a certain number of charge cycles, it will begin to degrade, and will no longer hold a full charge or last as long. When laptop batteries are reported as having 'poor' condition, or are exhibiting other problems, you may need to replace your battery.
Memory Test - RAM is very susceptible to damage. Static, heat and even normal air moisture can damage the RAM used to store your Mac’s workspace. The memory test uses a basic algorithm to test for basic problems with your RAM.
