Wrecks Everything, but saves space

My hard drive went up by 10+ Gigs which was nice. But then when I tried to print it recognized my printer as usual but the print queue gave me an error saying I need to upgrade my driver with the vendor. Of course, my vendor has no updated software this new OS. What the heck is the point of that Apple? So now I can’t print.
Otherwise I’ve noticed some weird bugs with software like Crome, a window is stuck at full screen after watching a video. There’s still no way to share files from Finder to Microsoft Outlook, but other apps are present, useless. Various other apps show weird behaviors. The sound card is better at switching from Airplay devices to internal speakers. The previous versions would lock up the sound card every time it switched more than once and I had to reset the sound card process, now it seems to cancel it’s connection attempt after some time. The printer suddenly not working when it clearly recognizes the printer and can even get it’s status really drives me up a wall.
