Just a reminder that we are scheduled for a Sierra software update, beginning at 11:55 PM on Monday,December 14th. The update should be completed before any libraries open on Tuesday morning. On Tuesday morning (December 15th) we ask that libraries start one Sierra computer at a time and let it update before turning on another Sierra computer. If you have any problems with Sierra, please email firstname.lastname@example.org. OWLS staff will post updates if problems are reported. I will send out another reminder on Monday. Thanks and good luck!
