I added the links highlighted in the early fastback video.  such as 
https://pixinsight.astroprocessing.com/.   
I started having issues when I would check for updates.  I would get a message.. a number of updates downloaded , ready to install.  But then the update will fail installation and the log file would indicate something like " no permission to write file", or permission to delete file.   
like this:
Error: Unable to delete file: Permission denied: /Applications/PixInsight/doc/docs/PIDocReference/images/eqn_0009.svg[2024-01-12 18:16:44] End updater1: ERROR
I'm on a Mac  M2.   I know how to set permissions to give PixInsight permission to access all file, to write and modify so I was baffled.     It had always worked fine for the last 4 versions of PixInsight.    I finally chose the "Reset Updates" option.  I reverted back to only those  "update-xxx.auth" files.     I am using 1.8.9-2.    I did update to the new version of graftXpert.
  I am starting to watch some YouTube videos now about this topic.        Any insight would be appreciated.
