com.apple.hiservices-xpcservice
is the name of an XPC service that’s internal to macOS. If it’s hanging, that’s something that needs ot be investigated by macOS Engineering. I recommend that you file a
bug about that. Please post your bug number, just for the record.
When you file your bug report, please do the following:
Reproduce the hang.
Make a note of the time you saw the hang (it doesn’t have to be super-precise, but within 5 seconds or so).
Trigger a sysdiagnose log (per the instructions on our Bug Reporting > Profiles and Logs page).
Attach that log to your bug report, along with the time from step 2.
You wrote:
If the service is opening the unicode / timezone files below before it hangs, maybe the problem is with the ICU … data?
That’s unlikely. The fact that the process has the timezone file open is no indication of where it hung. If you want to get a rough idea of where it hung, use Activity Monitor to create a spindump of the process.
IMPORTANT A spindump is not a substitute for a sysdiagnose log. Feel free to poke around in the spindump for hints as to what’s failing, but make sure your bug report has a complete sysdiagnose log.
Share and Enjoy

I am having the same issue with a new 13" MBP (2020 M1 Big Sur) with a very lean system build. The problem is intermittent and difficult to reproduce, so the following may not be correct, but I think it might only be happening when both of the following are true: (a) upon wake from sleep and (b) when connected to my external display (an Apple Thunderbolt Display).
As the Hiservices framework contains interfaces for internet config, I wonder if it could be related to switching network interface from wifi to Display Ethernet.
I believe I have ruled out anything having to do with Date & Time, as I have "Set time zone automatically" turned off, together with the applicable Location access in Security & Privacy.
Other things I had initially suspected that I have ruled out so far:
Any apps with Accessibility access;SteerMouse Manager;Bartender 4;Carbon Copy Cloner's daemon;MS Exchange calendars; andParallels 16.5.I also have an older 15" MBP (2018 Big Sur, Intel obviously) with a nearly identical software build and it does not have the issue. And a 13" MBA (2020 M1) which also does not have the issue. I am completely baffled and I am seriously considering erasing the 13" MBP and starting over with a fresh copy of Big Sur.
I hope this helps and we can get to the bottom of it.
