🐞: [BUG] High CPU Usage (45%+ CPU usage on M2 Max) during an active Time Machine Backup on macOS 26, Sample file attached

[SukkaW]

Describe the bug

During Time Machine backups, TimeMachineStatus uses more than 45% of CPU, even higher than the Time Machine itself (backupd):

To Reproduce

1. Manually trigger a Time Machine backup or wait for an interval backup
2. Monitoring the CPU usage of TimeMachineStatus

Expected behavior

TimeMachineStatus should not use this much CPU.

Screenshots

Attached above.

Additional context

Here is the Sample file created by "Activity Monitor", hope this helps:

Do you have the option "Animate Icon" ticked on? If so, try disabling this as a workaround. I haven't had the time yet to investigate this further unfortunately.

@lukepistrol Can confirm, with "Animate Icon" option disabled, the CPU usage drops immediately back to normal (about 10% or less).
