I have two Macs, a M4 Mac Mini at home and a M5 MacBook Pro for on the go. Recently I found I forgot to install an app on the MacBook and had to do so on the go. It wasn’t a big deal but it led me to think, what’s on both machines.
Some Gemini-Fu revealed a simple Terminal line that I ran on both Macs:
Open terminal and run:
ls /Applications > ~/Desktop/apps-list.txt
It then places a list of apps on your desktop in a txt file.

I then went to Claude and asked it to the following:
Please take these two files and put the list in each into columns on an Excel spreadsheet to allow comparison between the two computers.
I then dropped both files into the input box.
Seconds later, an Excel spreadsheet, with colour coding showing what’s the same and what’s missing.



Very cool! My apps list in PDF is here.
