spontaneous reboots mac-mini mavericks
Hi,
I recently noticed spontaneous reboots from a mac mini 2011 running Mavericks 10.9.5.
I scanned the system log files associated with the reboots, and it seems to me like there was a possible break attempt, each time (4 times in total over 3 days).
However, I would like to have this confirmed, and some efficient receipe to prevent these breaks (I'm connected to the public network through a Netgear NAT router).
To avoid any useless discussion, I attach to this request the 3 relevant log files : each time the keyword to locate the possible break is : BOOT_TIME.
Could someone please help me ?
The break seem to originate either from China or Turkey.
Thanks in advance from any help. Regards, G.G.
PS1 I don't know how to attach the log files.
PS2 Here is an excerpt from one of them : if more details are required, please ask !
