This lookup is used by other analytics. Why not rename the field in your search instead?

The original query had a rename (left it in here commented out), but it never matched any processes on macOS hosts:

earliest=-24h index=nvm process_name=* AND dst_name!=*.cisco.com 
| stats values(dst_name) as Destination by logged_in_user_name, process_name 
| join process_name 
    [| inputlookup remote_access_software_combined
        ```| rename remote_utility as process_name``` 
    | where isnotnull(process_name) 
    | table process_name, category, comment_reference, description, remote_appid, remote_domain ]

Here is a working example from the repo renaming the field to process for use

security_content/detections/endpoint/detect_remote_access_software_usage_process.yml

Lines 23 to 32 in 5fa7311

[| inputlookup remote_access_software where isutility=TRUE
| rename remote_utility AS Processes.process_name
| fields Processes.process_name]
AND Processes.dest!="unknown"
AND Processes.user!="unknown"
by Processes.action Processes.dest Processes.original_file_name Processes.parent_process Processes.parent_process_exec Processes.parent_process_guid Processes.parent_process_id Processes.parent_process_name Processes.parent_process_path Processes.process Processes.process_exec Processes.process_guid Processes.process_hash Processes.process_id Processes.process_integrity_level Processes.process_name Processes.process_path Processes.user Processes.user_id Processes.vendor_product
| `security_content_ctime(firstTime)`
| `security_content_ctime(lastTime)`
| `drop_dm_object_name(Processes)`
| lookup remote_access_software remote_utility AS process_name OUTPUT isutility description AS signature comment_reference AS desc category

I'm no expert on SPL but I think this might be an issue in your search.

But imo the solution is not renaming the lookup to fit (only) your need.
