But if you’re unlucky enough to be a Mac user in the month of December, 2017, then you’ll probably be seeing a lot of “Month 13 is out of bounds” messages in your Console. And by ‘a lot,’ I mean an exceedingly excessive never-ending stream of spewage…<\/p>\n

Thousands and thousands and thousands of them—I’m getting anywhere from two to 20 per second, continuously.<\/p>\n<\/blockquote>\n\n

The plot thickens. Similar logs are generated by my iOS 11.2 iPhone, which is up-to-date. It seems like Apple patched over the Springboard crashing but the underlying calendar logic is still broken somewhere.<\/p>\n<\/blockquote>\n\n

I’m getting this and it is causing UserEventAgent to consume all my cpu and RAM. Only solution is to set the date back until November.<\/p><\/blockquote>\n\n

William Osman<\/a>:<\/p>\n

My MacBook Pro was rinsed by UserEventAgent. Took full use of CPU and memory. I had to force quit it within Activity Monitor every ten minutes to keep laptop running.<\/p><\/blockquote>\n\n

’Month 13 is out of bounds’: The official CoreFoundation ‘__CFYMDFromAbsolute’ source code is available online. You can see the new ‘ASSERT_VALID_MONTH’ define causing all the ‘Month 13 is out of bounds’ logs.<\/p><\/blockquote>\n\n

It’s appearing at least 20 times per second and other than disabling Bluetooth, I haven’t found a way to stop it.<\/p>\n<\/blockquote>\n\n

Wait, 10.13.2 didn’t fix the Month 13 is out of bounds problem?<\/p>\n<\/blockquote>\n\n

Update (2018-01-01): James Thomson<\/a>:<\/p>\n

I hate to tell you… it’s January here and Month 13 is still<\/em> out of bounds.<\/p>\n<\/blockquote>\n\n
