This is why you should just be test driving the Beta (ideally on a spare/old Mac) & not using it for production work. Spending a week sorting out issues caused within Beta software? Screw that.
i agree. its too easy to want to see the new software, but when you are running el capitan beta on your mac, new windows on bootcamp, ios 9 beta on your ipad, you see why they are betas. for me now, ill wait. it literally was a week. if you look on my posts youll see i dont post much about problems, and i was literally a new thread every day.
if only when i posted about windows 10 crashing id read about disabling the driver.
instead i wiped my bootcamp partition.
didnt regain the space. spent hours trying to get the space back.
reformatted.
recovered from time machine. takes hours.
lost my recovery partition.
tried for hours to get that back.
noticed i didnt have sound and had no way of getting it back. spent an hour trying to.
reinstalled but had to go back to lion.
reinstalled yosemite
realised that this meant i couldnt get files direct from time machine but then realised i still could through the finder.
reinstalled ALL of my apps.
copied across all my windows games again through usb 2..hours...
all good now.
