Hey, everyone. I recently purchased a completely re-done 2008 Mac Pro. I don't know if this is considered to be a Boot Camp or not, but it does have Mavericks, Windows 7, and 3 other OS X OS's prior to Mavericks. Here are some concerns I have and would love your feedback/advice on these questions: 1) There is a Mavericks update waiting, as well as 2 others from the App Store. In the past, I had a jailbroken iPhone, and when I did an update, I lost everything on there. Lesson learned, but I don't know if doing any of these updates, especially the Mavericks one, would undo what's been done, software-wise, with this Mac Pro 2008. 2) Along the lines of the above question, I just tried to install Senuti (I have it on my Mac Mini 2011), and I got a message that eluded to that Mavericks update being needed. (Sorry, but I didn't capture a screenshot.) Any idea what this is about? I paid about $16 for Senuti unlimited about 1 year ago, so I'm not sure how to proceed. 3) There is software that I've put on my Mac Pro that have a white "no" symbol (circle with line through it) over the icons. What does this mean? One of these icons is Senuti.app listed in the list of downloads. Thanks!
