recoving files from a mac disk and w o n d e r s h a r e is unethical
If you search for cgsecurity.org testdisk, which is a free opensource utility to recover data from a disk, you get SEO'ed to w o n d e r s h a r e's website. Whilst w o n d e r s h a r e does make good software, I think this is entirely unethical. Hence I decided to make this blogpost to help others avoid paying them when free software exists and they are being predators trying to hide this fact by SEO'ing free software to their commercial site. Let me explain how unethical this is. It is like if you google for "wikipedia" and it opens encyclopedia britannica as the first thing and offers you a subscription only option to read the contents.
So, if you have lost files on a disk, try cgsecurity.org first.

These instructions work for mac except you type the following into the Terminal
brew install testdisk
and then
sudo photorec /dev/disk6
or whatever the drive number is of the drive. In my case it was 6, probably in your case it would be 3, 4 or 5. To get the drive number, type
df
and look for the /dev/ entry in the table that comes up.
You can click here to download the app:

please note that it is actually open source and actually free to use unlike the "w o n d e r s h a r e" stuff above.

Why? Because he let me TEST the software and ACTUALLY recovery my files BEFORE paying him. EVERY other app requires you to pay to extract any files. Beware.
