BUG in system.log, DEPRECATED USE in libdispatch client. Strange things in system report [duplicate]

MacBook Pro 13" Mojave 10.14.6 2.3 Ghz 8 GB RAM 512 GB Memory intel I5 (4 cores)

I believe I accidentally deleted an important file days ago. Since, the CPU has been riding high, unit is very warm and battery fading. I believe a crash is going to happen soon. The idle wake ups in the activity monitor are tens of thousands, even seeing 1.4 million idle wake ups on kernel task.

I've erased and restored the computer at Apple today, and that seemed to work until I got home and it's started all over again. There is no extra software running (anti viruses or anything). I have done SMC and PRAM resets. Now, in the Console system log I've found this:

DEPRECATED USE in libdispatch client: Setting timer interval to 0 requests a 1ns timer, did you mean FOREVER (a one-shot timer)?; set a breakpoint on _dispatch_bug_deprecated to debug

Solution 1:

The message you highlight is not a bug in your system. It is supposed to be there, and it is not the cause of your problems with high CPU usage and fading battery.

I would suggest using Activity Monitor to identify which process or processes are actively using your CPU. These would be the causes of high CPU usage.

As you have already reinstalled, you might find that the CPU heat is not a by-product of high CPU usage, but rather a hardware problem (such as a cooling issue).
