Seems like for some applications, double-packaging is required

There are 2 different installers now, 1. Intel, 2. M1 (Apple Silicon)

You can yous this script to deploy and update zoom I have tested it on all my M1

!/bin/sh

# ABOUT THIS PROGRAM

NAME

ZoomInstall.sh -- Installs or updates Zoom

SYNOPSIS

sudo ZoomInstall.sh

Script to download and install Zoom.

Only works on Intel systems.

Set preferences

hdvideo="true"
ssodefault="true"

ssohost="xxx.zoom.us"

choose language (en-US, fr, de)

lang=""

CHECK TO SEE IF A VALUE WAS PASSED IN PARAMETER 1 AND, IF SO, ASSIGN TO "lang"

if [ "$4" != "" ] && [ "$lang" == "" ]; then
lang=$4
else
lang="en-US"
fi

pkgfile="ZoomInstallerIT.pkg"
plistfile="us.zoom.config.plist"
logfile="/Library/Logs/ZoomInstallScript.log"
processname="zoom.us"

killall "$processname" &> /dev/null
if [ $? -eq 0 ]; then
echo "Killing $processname"
fi

Are we running on Intel?

I found that the regular Zoom install package includes a Universal binary now, so you can use that on both platforms.

I’m really not sure why they’ve released a separate “M1 Only” package at all. I checked both and they seem to install the same app on Apple Silicon Macs.

Like @UESCDurandal stated just use the Zoom IT Installer (Universal package):
https://zoom.us/client/latest/ZoomInstallerIT.pkg

Using the ZoomInstallerIT.pkg in script still gets me the Rosetta 2 requirement as of 08January.
Script result: installer: This package requires Rosetta 2 to be installed.
Please install Rosetta 2 and then try again.
sudo softwareupdate --install-rosetta

installer: Error - Zoom can’t be installed on this computer.

Just confirming that the IT installer (ZoomInstallerIT.pkg) that Fernando mentioned above also works for me. The installed binary is a universal binary.

# file /Applications/zoom.us.app/Contents/MacOS/zoom.us

/Applications/zoom.us.app/Contents/MacOS/zoom.us: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64:Mach-O 64-bit executable arm64]

/Applications/zoom.us.app/Contents/MacOS/zoom.us (for architecture x86_64): Mach-O 64-bit executable x86_64

/Applications/zoom.us.app/Contents/MacOS/zoom.us (for architecture arm64):  Mach-O 64-bit executable arm64

Just create two smart groups, once for Intel Macs w/o Zoom and one for M1 Macs w/o Zoom. Scope two different packages to two different sets of machines.
