So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.

Running into this error message when trying to run a mosh server on macOS Catalina? The steps below should solve the problem which is most likely either a $PATH and/or firewall issues.

command not found: mosh-server
Connection to X.X.X.X closed.
/usr/local/bin/mosh: Did not find mosh server startup message. (Have you installed mosh on your server?)

1. Install Mosh

Step 1

Download and run the Adobe Creative Cloud Cleaner Tool, their multi-app uninstaller and wipe assistant. Adobe does recommend running individual application uninstallers first, your call. Click the Clean All option.

Step 2

Type a one line command in terminal find ~/ -iname "*adobe*" and it's shows up all files which match pattern.

To remove all files

`sudo rm -rf /Applications/Adobe* /Applications/Utilities/Adobe* /Library/Application\ Support/Adobe /Library/Preferences/com.adobe.* /Library/PrivilegedHelperTools/com.adobe.* /private/var/db/receipts/com.adobe.* ~/Library/Application\ Support/Adobe* ~/Library/Application\ Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/com.adobe* ~/Library/Application\ Support/CrashReporter/Adobe* ~/Library/Caches/Adobe ~/Library/Caches/com.Adobe.* ~/Library/Caches/com.adobe.* ~/Library/Cookies/com.adobe.* ~/Library/Logs/Adobe* ~/Librar

I have found that Adobe services still worked fine after doing this, but your milage may vary, so be sure to have a back-up of your original install media or whatever.

You may or may not have these services, you can lookup what is running on your machine with launchctl list |grep -i adobe also run with sudo to find what is running at higher privledges.
