3. Mount the DMG and copy the install package to a writable temporary location in the local filesystem

$ cp -R /Volumes/MarkLogic/ /Users/[your_user_name]/tmp

4. In a Terminal window, edit Contents/Resources/InstallationCheck in a text editor (e.g. vim or nano)

$ vim /Users/[your_username]/tmp/MarkLogic-[downloaded_package_version].pkg/Contents/Resources/InstallationCheck 

Note: As an alternative, in the GUI-Finder, right-click and "Show Package Contents”. Navigate to “Contents/Resources/“, and edit the file “InstallationCheck” with a GUI text editor.

5. Delete or comment out the block starting with (lines 46-52) and save the file “InstallationCheck”:

 46 echo "Checking for Intel CPU"
 47 if [[ $CPU_TYPE != "7" ]] ;
 48    then
 49    echo "MarkLogic Server requires a CPU with an Intel instruction set."
 50    exit 114;     # displays message 18
 51 fi
 52 echo "$CPU_NAME is an Intel CPU."Save the file and back out of the folder

6. Install the MarkLogic package from the GUI Finder or CLI as intended. [3]

Conclusions
• The procedure in this knowledge base article allows to install MarkLogic Server on macOS Rosetta2 - Apple Silicon M1 / M[x]. 
• MacOS is supported for development only. Conversion (Office and PDF) and entity enrichment are not available on macOS. [4] 
• The legacy installation check is removed starting from MarkLogic 10.0-10+ release.
• Once the legacy check is removed, Rosetta 2 emulation software will be still required till an official native M1 / M[x] MarkLogic Server package will be available.
