Should fix a bug in which T2M2 reports an error message rather than completing an analysis of Time Machine backups.
CTS
It looks much the same as Sierra. Looking at High Sierra’s logs, though, shows that there are significant internal changes. Here’s a first glimpse at SkyLight, APFS and dasd at work.
Tools to explore and use the DAS and CTS scheduling and dispatching systems in Sierra and High Sierra.
Scheduling background activities like making backups has moved from cron to launchd, and now to a more complex system. This has reduced the reliability of macOS and made it harder to support.
Automatic backups will still become irregular or fail altogether, making Sierra 10.12.6 unsuitable for servers and systems requiring sustained operation.
How to diagnose this bug, manage it when it occurs, and try to prevent it from happening: latest information.
Lack of sleep can do strange things to people. Perhaps it can to Macs too. Could this solve the Time Machine irregularity bug?
Sleep interrupts the scheduling and dispatch of background tasks. Here’s how it looks in the dispatching systems.
Time Machine backups are but one of 70-80 background services which are run by macOS dispatching systems. Here’s a list of some of the others.
When scheduled backups become irregular or stop, this affects much more than just Time Machine. This is what happens, and why you must restart.
