Today marked the first day of Apple's public beta testing program for OS X Yosemite, letting thousands of non-developers download the software for the first time. With so many new users, new issues and bugs in the beta are coming to light and being catalogued in our Yosemite forum. We've pulled out some user reactions from the forums to share, along with some tips on troubleshooting possible issues. For users having problems with the beta, the Yosemite forums can be an invaluable resource, and for users still debating whether or not to install the beta software, make sure to check out this post and our forums before taking the plunge as Yosemite is still somewhat unstable. First Impressions A lot of new Yosemite users think that the operating system looks great. According to one user, it makes Windows and Mavericks look antiquated in comparison with its new focus on translucency and clean lines. A "Yosemite is Beautiful" thread is full of praise, with users calling it "stunning" and "the best OS X has ever looked."
