Download of RetinaCapture 1.3.5 for Mac was available from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free Mac app is an intellectual property of Matt Rajca.
The program lies within Design & Photo Tools, more precisely Screen Capture. The RetinaCapture installer is commonly called RetinaCapture.zip.
According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software. The most popular version among the program users is 1.0. This free app works fine with Mac OS X 10.8 or later.
From the developer:
RetinaCapture is a smarter screenshot capturing on Retina Macs. The app makes this easy by simultaneously taking a 1x and 2x resolution screenshot and saving both to a single directory. And since the 1x screenshot is redrawn at the lower resolution rather than scaled, everything looks crisp.
You may want to check out more software for Mac, such as ScreenRecord Studio, Screen Mimic or Sequence, which might be similar to RetinaCapture.
