Yosemite 10.10.3 w/iMac Graphics Update and 10.10.3 Supplemental Update Remains Stable

The test this morning was to load the additional maintenance which Apple sent recently, some of which appears to be close to a direct hit on the problem.  That test began seven hours ago on a standalone Yosemite 10.10.3 system with zero third-party software installed.  The maintenance was applied and we sat back to wait.  Given the longest this late-2013 iMac stayed up during the prior Days of Despair was eight hours, the stock Yosemite 10.10.3 performance now is impressive and convincing.

The problem looks like it comes in some of the additional software running here but that still doesn't get Yosemite off the hook because there was no warning of potential incompatibilities and one would not normally expect to find that coming from a maintenance upgrade.  That aspect is philosophical and can play all in good time.  Meanwhile, I'll get to rebuilding this thing.

Safari is the only product running and I have not even opened Mail.  This time I refuse to be sucker-punched by anything and that, regrettably, means moving very slowly.  In part I tell this to myself as you've got to know I'm hatin' it.  There's great relief today, tho.  Now it moves forward rather than backward and no-one ever wants to re-trace steps.  The dragon with the pot of gold is up forward somewhere.  Got to get there.
