The Mac clock randomly goes out of sync.

Good evening,

Check in the system preferences / date and time that the box asking to set the time automatically is checked. Also, make sure you have selected the correct time zone.

Also check in Windows - to ensure that the settings of one OS do not conflict with the other OS.

Best regards

Good evening
I have of course checked the box to set the time automatically, I even found my city in the time zones.
In Windows, I left the default options but I repeat: the problem appeared long after the installation through Bootcamp, and the problem had never occurred on the PC before a week ago...
I'm not so sure, but the problem appeared a little while after I reinstalled my Mac system with a clone made by Super Duper.
I made the connection without seeing anything conclusive.
Any ideas ???

Good evening Sanspseudo,
first of all, thank you very much for answering my question, the outcome of which is ultimately not very important, and thank you for your contributions to this forum :-)
What do you mean by

We should then try to modify these preferences in Mac OS, and then set them back according to the final wish.

Is there somewhere on my Mac one preference file?
Thank you...

Is there a preferences file somewhere on my Mac? Thanks...

There are actually several preference files, but the "date and time" preferences are included in the global system preferences file; unfortunately, it is not a SINGLE file. Otherwise, I would simply recommend deleting this file and redoing all preferences.

Regarding this, it is possible with iTweax to check the integrity of preference files in Mac OS 10.
http://www.itweax.net/
You need to go to the "Maintenance / Misc" tab / Check preferences and request to show only corrupted files.

Under Mac OS 10.6, all preference files are in
Users / Username / Library / Preferences ...

Too bad it is not possible to avoid Windows for at least some time...

here is the response from iTweax

 Toxic MACak March 27, 2012 at 01:11 thanks here is the reply from iTweax /Users/none//Library/Preferences/com.apple.iphotomosaic.plist: Conversion of string failed. The string is empty. Finished Checking .plist files.

This preferences file has nothing to do with the issue, but it is good to throw it away since it is corrupted. The system will create a brand new one at the next launch of the concerned application. (iPhoto, it seems).

But, I would like to add something, on desktop Macs, the date and time are part of the elements permanently saved thanks to an internal battery in the Mac. I didn't mention it since it's a recent and portable Mac.
But you never know?
Is this Macbook pro equipped with such an internal battery? I don't know. I assume that laptops, especially those with a non-removable battery, do not have one, but to be honest, I don't know. This brings me to another lead. Does the phenomenon also occur when the Mac remains connected to the power supply? Or only after being unplugged for a certain amount of time? (with an empty or dead battery).

Yes, the 13' MacBook Pro is equipped with an internal battery independent of the main battery.
It's in this context that I performed the PRAM and NVRAM reset:
quote from Apple's website

Resetting the PRAM and NVRAM Turn off the computer. Locate the following keys on the keyboard: Command, Option, P, and R. {.....} The PRAM and NVRAM of your computer are reset to their default values. Clock settings may be reset to a default date on some models.

Furthermore, I only use my Mac while plugged in.
I would add that my clock is always 1 hour fast (now 2),
always ahead and never behind,
the minutes are always accurate ..... I concluded that the problem did not come from the battery!!!

Hello,
Geneva, Switzerland
What is the connection?
--
Of random recurrence

Yes, indeed.
But in this case: Geneva and Brussels-Madrid-Paris are in the same time zone, right?

For now, my hypothesis is that there might be an issue with my permissions on the Mac:
- because we have the option to leave the little padlock unlocked in the system preferences window.
but every time I turn it on, it is locked again, no matter what I left before.

- When I check the permissions, there are always a few lines "not restored,"
notably the thing about "RDA Agent."

- I often (but not all the time) have my Littlesnitch notifying me at startup + internet connection that there’s some "locationD.something" trying to establish a connection, which I allow each time.

Thanks for your patience :-)
Random recurrence.

I have to step away right now. I will come back. But in the meantime, it’s normal for the lock to close automatically.

As for "the RDA agent," I will check on the Apple site if that’s part of the messages we shouldn’t pay attention to. (There are several).

Regarding Little Snitch, it would be good to note the exact message...

ok
I have already looked into the ARDA on Apple’s site, and they have a reassuring message... But elsewhere, I’ve read other information that's much more concerning, like it being a gateway for malware.
As for the links and exact quotes, that won’t be until 7-8 PM tonight, because I'm working right now (even if I don’t seem like it ;-) and so I'm booted on the PC, and I don’t have time to reboot the Mac + reboot the PC, etc...
So thanks again, and see you tonight --

Good evening
not on time but present...

What little Snitch tells me is "Locationd wants to connect to iphone-wu.apple.com on TCP port 80 (http)", I think because once, I connected an iPhone to my Wi-Fi network so that it would subsequently emit it for me to connect to the net later with my Mac

..if little of not much

Good evening,

Regarding the messages during permission repairs, nothing unusual. The message is included in the list of lines that can be ignored
http://support.apple.com/kb/TS1448?viewlocale=en_US&locale=en_US

As for the Little Snitch message, it's a bit strange because I don't see why the Mac would attempt to connect to this thing that seems to be linked to an old tracking system placed on iPhones, which has been removed in the latest iOS versions, but also to some spyware that might be lurking on the Mac and that could indeed be related to time zones. Block this communication, and search the Mac to find the related application. Check out this page:
https://superuser.com/questions/36428/what-is-locationd-and-why-is-my-3rd-party-firewall-intercepting-it-in-snow-leopa

Do you have something with "skyhook" in its name on your Mac?

EDIT: I think we should also look on the Windows side..

One thing, install an antivirus, even in demo version, on both Mac and Windows sides.

Perform a thorough search with EasyFind

re

thank you for easyfind :-)
I've searched everywhere and in every way, no traces of "skyhook"
on my mac.

Additionally, I would like to exonerate the PC because I reinstalled it this weekend, but the problem persists. (I erased my bootcamp partition, created a new one, reinstalled windows as if it were the first time!)

here's the text that raises concerns about the ARDA, maybe I didn't understand everything, but it seems to me that we're talking about a breach in the so-called "invulnerable security of the Mac":

Hello,

The information provided by this site is quite old. Since that vulnerability, which was acknowledged by Apple at the time, there have been a slew of security updates.
https://support.apple.com/en-us/HT201222

Is there, by any chance, something enabled in the System Preferences under "Sharing," (especially in "Remote Login" or "Remote Management")?
In any case, I suggest blocking the communication via Little Snitch when the message "'Locationd wants to connect to iphone-wu.apple.com on TCP port 80 (http)" appears.

Hello,

I don't understand what you mean by

 something is enabled at the "Sharing" level, 

For the Little Snitch message, I now have it set to "forever deny"...

thanks again for continuing to respond to me :-)

Of random recurrence

If you open the System Preferences, you will find a "Sharing" button.. and from there there is the possibility to share things from the Mac and to allow, in particular, remote login on the Mac, remote management of the Mac, and other things of that kind.

(this is a feature I use when transferring files between my iPhone and my Mac with the Briefcase app)

For that, the firewall also needs to be partially open. So, the firewall settings need to be checked in the "Security & Privacy" button as well.

Now, simple supposition, if these shares have been activated, it would allow a stranger to remotely access your Mac... I don't want to be paranoid, but let's check all possible points.
I don't use Little Snitch, and therefore I don't know it well, but I use VirusBarrier which includes a pretty effective and customizable firewall. So I see all the attempts coming through.
They say that very few viruses exist for Mac, and it's true because you can count them on one hand, but on the other hand, intrusion attempts, phishing, attempts to take remote control, spying...etc.. are just as frequent as on a PC, since in this case there is no difference in protection at the base between the two systems. I have plenty of blocked addresses on a blacklist on my Mac as a result of these attempts. So let's be vigilant.

Thank you :-)

Quite paranoid on my part, my sharing is completely disabled.
This doesn't prevent me from seeing other Macs available on my network (and them seeing me), but it seems to me that if everything is disabled there is no way to take control of my machine.
(note: I only connect to the internet via Wi-Fi, leeching off the public network at the train station across from my house)

Okay, in principle, I am willing to admit a possible intrusion into my system,
but still, why go through all that trouble just to merely advance my clock? (I know stupidity reigns supreme in our world, but still, one would have to be both stupid and very skilled at the same time)

Do you think this little clock problem is just the tip of the iceberg of hacking?
If so, what can I do?

--

Random recurrence

To be honest, no, I don't think this clock problem is the tip of a hacking iceberg. If that were the case, the hacker would be smarter and would avoid giving signs.
If there is a deliberate intrusion, it would be the work of a prankster, but I rather think it's a background task resulting from remnants of an application tested or previously used. The message "Locationd wants to connect to iphone-wu.apple.com on TCP port 80 (http)" was linked to a controversial tracking system but for those who used an iPhone. A "feature" that has since been deleted in the latest iOS for iPhones. What I’m trying to understand is why this message on a Mac and why an app on Mac is trying to communicate on this port ...

I found other cases:
