OS X Compatibility
The following (and all newer) versions of our products are compatible with OS X 10.9 “Mavericks”:
Previous versions may be compatible, but have not been tested.
As always, we recommend keeping your OS up to date, in order to get the latest fixes and improvements from Apple.
We cannot fully support the use of our products on beta versions of OS X.
If you encounter difficulty when using the latest version of BBEdit, TextWrangler, or Yojimbo on any pre-release version of OS X Yosemite, please first verify whether the problem also occurs when running on the latest public release of OS X Mavericks (10.9); and then file a bug report with Apple using an appropriate feedback channel. They will contact us as necessary.
