Month 13 out of bounds

Hi all,

I noticed today my RAM is being seriously depleted, getting fan noise which has almost never happened previously, some applications running super slow.

Specs: Macbook air, 13 inch, early 2014, 1.4 GHz Intel Core i5, 8 GB RAM, running 10.13.1.

Checked Activity Monitor. memory usage is at 7.5 of 8 GB (normally it's around 4-5), UserEventAgent is up around 80-90% CPU. Checked Console: getting continuous "Month 13 is out bounds" error messages across many processes.

Checked around online, noticed a few others having same problem (e.g. high sierra - Month 13 is out of bounds? - Ask Different). The suggested work-around there is to change the system date so current date is no longer Dec. This did in fact work, RAM usage back to normal, but it messes up other applications (e.g. dates in FileMaker database), so not really a viable solution.

Anyone else coming across this, have ideas or fixes?

Thanks.

MacBook Air (13-inch, Early 2014), macOS High Sierra (10.13.1)

It still doesn't address the underlying issue, and also doesn't completely fix the CPU usage either. It just makes the computer usable...

Good idea, feedback report filed.

I don't know if my situation is different to other people but I've been experiencing the Month 13 error for weeks (probably since I first installed HS), not just since 1st Dec.

Mine started Dec 1 and after the two High Security Updates closing the "root" flaw and then the "File Sharing" flaw introduced in the first fix. Draw your own conclusions.

I agree... I would also like to go back to a previous version. I don't know how to do that however! 😕 very frustrating at the very least.

Spoke to engineer at Apple "unaware of an issue" but have asked to me send them log files....fingers crossed!

Oddly macbook is fine, imac however about to get thrown out a window.

Have read on apple developers forum that this 13 month out of bounds issue was known since November 30 - December 1 - - so engineer at apple is out of the loop or *$%^& us around

Dec 4, 2017 2:03 PM in response to PRP_53

Yeah I felt like they were playing 'dumb' about it when I spoke to them. Hopefully there is a patch or new OS soon as imac is unusable.

checked plist, I don't have that. So looks like different things for different people 😟

Not third party as it also happens in safe mode

Dec 5, 2017 8:26 AM in response to rd_8888

it would seem Apple created this >> therefore Only Apple can fix it

Once again, nobody is saying that the "Month 13 out of bounds" messages in the Console are third party. Apple has said that's there issue.

Exactly what else are you seeing in safe mode?

Hum, try looking in About this Mac>>System Report >> Installations. Does anything appear as being installed after the Root Security and File sharing Patches were installed?

Disk Doctor could be the source of some of your issues
