WARNING: Hasnt been updated since 2012.

Patterns is THE BEST regex app in the Mac App Store.

But it hasnt been recompiled and updated to be compatible with OS X 10.11 El Capitan. It hasnt been updated since 2012- FOUR YEARS AGO. It is crashing for larger search text. It is showing its age and incompatibilities when it crashes..

At this point in time, it is sad to say but it is abandoned.

Ill keep it for simple text samples. But I wish it is at least recompiled with the latest X-Code to make sure it is compatible with OS X 10.11 El Capitan.
