Comment (by danchomichev):

 (1) The computers I have used are/were Windows computers. This is my first
 Macbook and this is the basic information about it:
  Model Name:    MacBook Pro
   Model Identifier:     MacBookPro18,1
   Model Number: MK183LL/A
   Chip: Apple M1 Pro
   Total Number of Cores:        10 (8 performance and 2 efficiency)
   Memory:       16 GB
   System Firmware Version:      8422.121.1
   OS Loader Version:    8422.121.1
 (2) I am using Kile on the Windows machines. I like Kile mostly because of
 the "Live Preview" feature in this LaTeX IDE.
 In that sense the situation is not "critical" for me and I can wait; I
 just want to use Kile in MacOS.
 (3) I initiated this ticket, because my feeling is something should be
 fixed because of the relatively new "arm64" architecture.
 It is not a problem for me to wait, and I am willing to help as much as I
 can.
 (4) Thank you!
