I posted about this on Facebook but I thought I'd mention it here too. When MacOS X first came out, there were very few scanner drivers so I bought VueScan. Even if you can get the manufacturer’s scanner driver, it’s usually not half as good. I bought the Pro version which means I get free updates forever and it has been a godsend. When you buy a new scanner, you don’t have to install or learn any new driver software. I have 2 scanners, an Epson Perfection 4990 Photo and the one in my HP Envy 4500 multifunction printer. Using VueScan for both makes life mch easier. Oh, and it's available for Macs, Windows machines and Linux. See the VueScan website. I have no association this company and receive no referral fees. I only mention it because it is a great piece of software which has served me well for many years and deserves to be better known.
