I can not update to El Capitan if XtraFinder is not supported. And it seems that Sytem Integrity Protection has to be disabled all the time to run it. So my questions would be: - Is it really dangerous to have SIP disabled all the time, or it will be just as dangerous as Yosemite has always been? - What is your experience guys running XtraFinder under El Capitan? If XtraFinder does not work in El Capitan, I just can not update OSX, I got so used and dependable on Xtrafinder, so much much better than the regular finder, that if it's necessary to stay in Yosemite, I will do so.
