Hi guys! I downloaded Yosemite Zone ISO and DMG files and I try to take, in some ways, Mac OSX Yosemite on my Lenovo Z50. I succesfully installed it on Virtualbox, but it is too slow (I think it's because I have only 6 gb of RAM and I can't assign to virtual machine more than 5 gb). So i would try to install it on my USB 3.0 external drive, to use it with I have a question: if I try to install Yosemite on my USB drive, the internal drive of my pc isn't touched, is it? If I boot my pc from the hard drive Windows 8 will start without problems right? Then, which kexts I have to install for my laptop? These are the specs: 4th Gen Intel® Core™ i7-4510U (2.00GHz 1600MHz 4MB) (2.60 GhZ with Turbo Boost)Intel HD Graphics 4400Nvidia Geforce 840MRealtek Wi-Fi CardI really need only Wi-Fi to work and not slow performance (I would use it only for XCode programming and iOs simulator). Maybe a good battery managing. Can you help me? Thank you!!
