Travis posted a question in Hackintosh SierraI built a Hackintosh on a GIGABYTE GA-EP45-UD3P in 2010, and upgraded it to Sierra about 4 months ago. It's been working great until a few days ago. The clock now is losing time, while the computer is on and running. I've been working on the computer all morning, and have had to bump it forward to the current time it 3-4x. Right now it says 9:40am, but it's really 9:47am. I have "Set time and date automatically" set in settings and "Apple Americas/U.S. (time.apple.com.)" selected on the drop down. Deselecting it, and selecting it again, brings the clock back to the current time. Is this a hardware issue or a software issue? Do I have to replace the CR2032 on the motherboard? If so - why? The computer is on, and running, why would it need that battery to maintain the time?
