If you want it on USB in stead, the steps are simpler (the link below also links to other OS X and MacOS versions):

macos – How can I modify the list of Applications under ‘Open With…’? – Ask Different

Posted by jpluimers on 2019/11/22

Some interesting links on the “open with” database:

Simple solution to clean the list:

# Clean up LaunchServices to remove duplicates in the “Open With” menu.
alias lscleanup="/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user && killall Finder"`

These were by products of what I was really searching for:

Why are some items grey when modifying the “Open with…” settings?

Some applications are greyed out, for instance when editing the “Open with…” for the .cap extension (which are pcap network captures that Wireshark can process).

After the steps below, sometimes the menu still does not update for all files of that extension.

This alias helped me to get that to work: alias restart-finder='killall -KILL Finder'.

Links that helped me finding out:

The trick is to toggle “Recommended Applications” into “All Applications”:

Then you can select “Wireshark.app”:

 

The same happens when you filter on a name (for instance because you know that Wireshark will work fine):

A final thing is that you have to check “Always Open With” so it ends up in the list.

TestDisk, Data Recovery; free and open source

Posted by jpluimers on 2019/10/28

Interesting tool that I needed one day to figure out how to recover from a certain NTFS partition having become RAW [Archive.is/WayBackTestDisk, Data Recovery:

TestDisk is powerful free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software: certain types of viruses or human error(such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.
TestDisk can
  • Fix partition table, recover deleted partition
  • Recover FAT32 boot sector from its backup
  • Rebuild FAT12/FAT16/FAT32 boot sector
  • Fix FAT tables
  • Rebuild NTFS boot sector
  • Recover NTFS boot sector from its backup
  • Fix MFT using MFT mirror
  • Locate ext2/ext3/ext4 Backup SuperBlock
  • Undelete files from FAT, exFAT, NTFS and ext2 filesystem
  • Copy files from deleted FAT, exFAT, NTFS and ext2/ext3/ext4 partitions.
TestDisk has features for both novices and experts. For those who know little or nothing about data recovery techniques, TestDisk can be used to collect detailed information about a non-booting drive which can then be sent to a tech for further analysis. Those more familiar with such procedures should find TestDisk a handy tool in performing onsite recovery.
