I still don't allow my fiance to update to El Capitan for one simple reason, he uses VirtualBox with Windows 8 on it and two USB hardware keys. I keep on reading that Cappy ruined VB's USB capabilities and that a fix is coming sometime, somewhere, somehow. For me it's Cubase which would start and make no sound in 10.11, and now just crashes in 10.11.1 which I assume is a new feature. /s Obviously XtraFinder won't put folders on top, and SIP has to be disabled for XF and cDock to work at all. So in general El Cap proved to be Yosemite without stability and with introduced features that make it difficult or impossible to use my software. Who knew at the end Yosemite would prove to be Snow El Capitan?
@Queen6 I wouldn't have much of a problem just downgrading to Yosemite, but I don't know if it's possible to downgrade a TM backup, I assume the answer is no, and I don't want to lose my TM :/
