In 2007 I bought a used dual 867 MHz processor G4 PowerMac from a friend. Included in that purchase was a license for a utility called Tech Tool Pro version 4. This is now up to version 21, licensed users of previous versions can upgrade to newer versions at a reduced cost.
The developers, MicroMat, have just released a free reduced-capability Lite version dubbed TechTool Lite, on my MacBook Neo it occupies under 50 MB of space vs 120 MB for the paid Pro version. The attachment shows the tests and tools which the Lite version can perform.
I have had to revert to the web app to upload the image from my Photos Library as the attempt to use Nice app on both Mac and iPad resulted in the “Failed” attachment issue once again.
