Look in twsstartmacos.sh. You’ll see the setting for the LOG_PATH variable. The log files themselves have names like this:

?

ibc-3.18.0_TWS-1025_wednesday.txt

?

Now read the descriptive comment further below. For your convenience, this is what it says:

?

#?? LOG_PATH

#

#???? Specifies the folder where diagnostic information is to be logged while

#???? this command file is running. This information is very valuable when

#???? troubleshooting problems, so it is advisable to always have this set to

#???? a valid location, especially when setting up IBC. You must

#???? have write access to the specified folder.

#

#???? If no value is set, log information is sent to the terminal window.

#

#???? If the setting is removed entirely (or commented out), no log information

#???? is captured at all (but this is not recommended).

?

I presume you are using twsstartmacos.sh to start IBC? If you aren’t, then how are you starting it?
