I wonder if its not to do with some untested hardware issue since apple using intel processors seem to have changed regularly the inners, things less current when under powerPC ( I still have 2 of them...). I am trying to figure out what in high sierra can make my powerbook pro of 2011 over heat... ( because I burnt my motherboard (graphics...) beginning July ) or go berserk from time to time, I have just assembled a new one but this time a late 2011 motherboard after buying a 2012 for later usage, and again it reaches over 40 C after 15 minutes not doing anything special, the 2012 is already in mojave but so far not much time to play with as still sick and just finished a 3 weeks antibiotics treatment... but into as I dont know anything about the inners of the Mac Pro and mac mini but if like the laptops I would not be surprised... Not insisting for now as we have a heat wave passing just now and was 34C yesterday ( last time it was 36C here...) Monday 25C announced so I will try again...
AS now Im using my wife's ( my ex-hospital usage laptop...) Macbook air which is now under Mojave and am surprised that it stays cool doing exactly the same thing and yes it does heat when I start heavy usage but never like the Macbook pro which can exceed 45 after only 15 minutes when I use it seriously...
My idea was to investigate on the heating control, could it be faulty for my old HW and so not reacting in time? as like you before burning it did crash a few times without to me any reason and I could not see anything in the logs explaining except a panic but can't find the cause...

SYNOPSIS

[options]
DESCRIPTION
The command converts a sequence of login/logoff records read from its standard input to a sequence of records, one per login session. Its
input should normally be redirected from or Its output is ASCII, giving device, user ID, login name, prime connect time (seconds), non-
prime connect time (seconds), session starting time (numeric), and starting date and time. Prime connect time is defined as the connect
time within a specific prime period on a non-holiday weekday (Monday through Friday). The starting and ending time of the prime period and
the year's holidays are defined in file
expects as input a sequence of login session records, produced by and converts them into total accounting records (see format in acct(4)).
combines the functionality of and into one program. It takes the same input format as and writes the same output as
recognizes the following options:
Print input only, showing line name, login name,
and time (in both numeric and date/time formats).
maintains a list of lines on which users are logged in.
When it reaches the end of its input, it emits a session record for each line that still appears to be active. It
normally assumes that its input is a current file, so that it uses the current time as the ending time for each ses-
sion still in progress. The flag causes it to use, instead, the last time found in its input, thus ensuring reason-
able and repeatable numbers for non-current files.
and recognize the following options:
file is created to contain a summary of line usage showing line name, number of minutes used, percentage of total elapsed
time used, number of sessions charged, number of logins, and number of logoffs. This file helps track line usage,
identify bad lines, and find software and hardware oddities. Hang-up, termination of (see login(1)), and termination
of the login shell each generate logoff records, so that the number of logoffs is often three to four times the num-
ber of sessions. See init(1M) and utmp(4).
file is filled with an overall record for the accounting period, giving starting time, ending time, number of reboots, and
number of date changes.
When this option is used, the records of the type found in
are read from the specified input.
