Please note: As of November 21, 2013, new shared web hosting accounts no longer include the Soholaunch site builder tool. Instead, we are pleased to include the HostPapa Website Builder with all new accounts.

The makers of Soholaunch have stated that their site builder will work with Mac, provided the operating system is at least OS X. However, there do seem to be some issues with the Safari browser when it is used to manage the website from the admin area. If you are using a Mac and want to use Soholaunch to create your website, you may want to consider using a different Internet browser, such as Firefox.
