Auto boot is one of the new features of both the 13inch and 15inch Macbook Pro (late 2016). When you either attach a power source or open the lid (barring there is enough battery power) the device will startup. 

Prior to macOS Sierra if you wanted to find out whether or not a Caching Server is running on your network you could open up the Console.app and search for "AssetCache" in the logs. This no longer works in macOS Sierra.

Now in Sierra you can use a new tool: AssetCacheLocatorUtil
Enter this command in the Terminal.app and watch it give you detailed information.
It will, in a very verbose manner, tell you if and where a Caching Server is located. It even indicates if "personal caching" is supported. What is personal caching? Simply put it's the server caching personal iCloud data.

One of the great new features in macOS Sierra is Apple Pay on the web in Safari. To use Apple Pay on your Mac you will need to sign into iCloud and have an iOS Device, also signed into iCloud, with a supported Credit card from a supported card issuer. When checking out on a site that supports Apple Pay, using the Safari browser, you can check out with just a touch thanks with the help of your iOS device. This makes purchasing items on your Mac simple and easy. 

The new 2016 13 inch and 15 inch MacBook Pro includes Touch ID and Apple Pay. This is a welcome addition and an exciting feature. The out of the box experience is to walk through the setup assistant, on your new MacBook Pro, which now includes setting up Touch ID and Apple Pay. Making purchases with Apple Pay will be even easier because you can leverage the Touch ID built into your Mac without the need of an iOS device. 

Something to consider. When setting up a second (or supplemental) user on your Mac, you will be able to setup Touch ID but you will not be able to setup Apple Pay IF another user already has it setup. In the event a second, third, fourth, etc user wants to leverage Apple Pay they can use Apple Pay on the web in Safari.

I viewed the system log files and saw the following error message every two minutes:

Nov 11 11:27:34 hcstest smbd[416]: in openpam_read_chain(): /etc/pam.d/other: Too many open files
Nov 11 11:27:34 hcstest smbd[416]: in openpam_read_chain(): /etc/pam.conf: Too many open files


I ran the “ulimit -a” command to see what the default open file size and Max user processes size were.  They were 256 and 709 which is very low.

ulimit -a 

core file size          (blocks, -c) 0  
data seg size           (kbytes, -d) unlimited  
file size               (blocks, -f) unlimited  
max locked memory       (kbytes, -l) unlimited  
max memory size         (kbytes, -m) unlimited  
open files                      (-n) 256  
pipe size            (512 bytes, -p) 1  
stack size              (kbytes, -s) 8192  
cpu time               (seconds, -t) unlimited  
max user processes              (-u) 709  
virtual memory          (kbytes, -v) unlimited  

I created two plist files that will change the default open file size and max user processes size limits to 524288 and 2048 and and put them in the following location:

/Library/LaunchDaemons/limit.maxfiles.plist

/Library/LaunchDaemons/limit.maxproc.plist

After a reboot, a re ran the ulimit -a command and the changes were now in effect.  I monitored the system log and these errors are now gone.

Mountain Lion (10.8) and earlier

You must never remove Lucida Grande. Without that font, the system will not boot. If you remove it while the system is active, you will lose control of all menus, essentially locking you out of your Mac.
