Ratings and Reviews
App is sunsetted...
App is great, but is sunsetted and will not be updated. Was great and BBEdit free will do the same things, in a free capacity and is updated.
Sometimes - people deprecate things - and this is one of them.
To all the people complaining, it was free. Seriously.
This app needs to be updated asap as the 32 bit apps will be gone very soon.
Remapped file extensions without asking?!
Are you seriously kidding me?? What kind of gall does a program have to have to just asssume it should be the default for all of the file types it supports. Not even so much as an alert confirmation!
Developer Response ,
The system has decided to make this change; not TextWrangler. However, you can use the Finder's "Get Info" window to change the application associated with a file (or all files of that type). If you're stuck, drop a line to "email@example.com" and we'll be happy to help.
Up to six family members will be able to use this app with Family Sharing enabled.
