How to Install S & S Windows Applications on a MAC Computer Using Wineskin

Wineskin provides free Windows emulation support to run S & S applications on a MAC.

What is Wineskin?

Wineskin is a tool used to make ports of Windows software to Mac OS X 10.6 Snow Leopard (or later). The ports are in the form of normal Mac application bundle wrappers. It works like a wrapper around the Windows software, and you can share just the wrappers if you choose (that is the strategy used here). Best of all, it’s free and does not require installation of the Windows OS!

If you are satisfied with this installation process, please consider making a donation to Wineskin in support of the excellent work they do in creating the Wine wrapper engine. A brief video tutorial explaining how to use Wineskin to create a Windows wrapper is provided at the bottom of this webpage. Current Version is v2.6.2.

Installation Instructions

1. Double click the download labeled “Wineskin Winery App”
2. Once the app has created a new desktop icon, which will show up in the same finder
   window as your download, double click on the Wineskin Winery icon.
3. This will bring up a security window, asking if you would like to open the Wineskin Winery application which was downloaded from the Internet (even though it is from an unidentified developer), select Open.
4. Once the app is installed, it will automatically open. Select the bottom option that says

Mac Says Pdf Is App By Unidentified Developer Download

Use the MAC Download button on the product page to download the zipped S & S application Wineskin Wrapper to the Download folder on your MAC. For example, if you are installing SewWhat-Pro, the zipped wrapper file will be named Wineskin-SewWhat-Pro.app.zip. Unzip it and run it to install the product. You may be prompted that “SewWhat-Pro (or whatever application you are installing) is an application downloaded from the Internet. Are you sure you want to open it?” Select “Open” to continue with the installation. You may have to change your security settings to allow the file to run, as explained here. The Wineskin programs will have a wine colored icon next to the file name after they are installed (see figure below).

Once the installation is successfully completed and you open the application, the S & S product application registration box will open. You may now choose to continue using the product as a Demo or enter your registration information if you purchased a license.
