Big Sur has recently introduced a bug which can change the format of log datestamps, which can break Ulbow, Mints and T2M2. Here’s how to fix it.
T2M2
For many, this could be the best reason for upgrading early. Even when it doesn’t go quite as expected, this really isn’t difficult.
Extends support for the new feature in Big Sur to make Time Machine backups to APFS volumes.
Performs special analysis of Big Sur backups to APFS, and runs native on Intel and Apple Silicon Macs.
The most common problems with Time Machine backups, and how to tackle them using free tools.
A detailed walk through the log extract delivered simply by Mints, showing steps in a normal Catalina backup.
New approach to reading logs which enables you to follow conversations between sub-systems and services you’re interested in without messing with predicates.
Time Machine can’t make backups to a disk formatted in APFS. Oh yes it can – and here’s how you can do it too.
One small change: you no longer need to press Tab or Enter to set the time period.
What do you try when T2M2, Ulbow, or another app which accesses the log, doesn’t work properly? Diagnosis and solutions.
