RU should get somebody that isn't a smart*ss to respond to these posts/questions. The tone is unprofessional, cringe-worthy, and a complete turn off to anyone that would be serious about spending several thousand dollars on software. I would not tolerate this from any kind of tech support I would be working with as a customer.
No Mac client is a non-starter for anyone serious about using this software as an MSP. If RU is serious about becoming mainstream, it needs buy-in from the MSP market segment. Telling us that a Mac client is "not important", goes a long way to demonstrate how out of touch this company is with the demands of consumers in a large market segment.
Don't bother to delete this, I plan to send a copy to the CEO via email anyway- hopefully it's not the person responding here.
