How to disable thermal policy for the icloud photo process? My Photo app has stopped updating the library for a while.
It seems to be hardware related. The temperature of the CPU is consistently around 72~73c even when there is no workload. The fan is always spinning.
This is what I see in the console log:

Here is the revelant text:

 ], FinalDecision: Absolutely Must Not Proceed\}\

It seems like, due to the thermal condition of my macbookpro, the icloud photo process has decided not to download any update.
However other icloud service seems to run fine and does not have this restriction.
Is it possible to disable this ThermalPolicy?
While the error messages are still present in Console, the Photo app is able to sync changes in the Photo library in iCloud after upgrading maxOS to version 10.15.6 (19G2021).
I find out that the real reason is not the upgrade itself. Actually it is due to the fact that I disconnect my external monitor during the upgrade.
I typically use my MBP with both of its primary monitor and an external monitor turned on. It triggers the thermal throttling which stops the iCloud photo sync from happening.
Whenever I disconnect my external monitor, the icloud sync will succeed.
