If a critical error occurs (the device will not start after turning on the power, etc.), repairs will be required. If the device is connected via LAN cable, disconnect the USB cable. If using a USB connection, do not connect the device through a USB hub as doing so may result in connection errors. If the device is connected via USB cable, disconnect the LAN cable. Configure your computer settings so that it will not enter sleep mode before performing the firmware update. If using the fax functions, disconnect the telephone line from the main unit.
How to upgrade mac operating system 10.8 to 10.12 update#
To prevent problems resulting from operations performed on other computers during the firmware update, performing the update using a USB connection is recommended. If your computer enters sleep mode, the firmware update may not be performed properly.

Do not turn off the device power, or disconnect any USB or LAN cables while the firmware update is in progress. If signals/data (print jobs, etc.) are sent to the device from another computer or application while the firmware update is in progress, a critical error may occur. If the update operation is performed while the device is processing other operations, or while images are stored in memory, those other operations will be canceled and the images stored in memory will be lost. If the Error indicator is on or blinking, refer to the e-Manual and resolve the issue, and then perform the update operation after making sure that the Error indicator is off. After the operation finishes, wait for the Processing/Data indicator to turn off. When the Processing/Data indicator on the operation panel is on or blinking, the device is processing operations. When updating the firmware, be sure to wait until all operations (copy function, etc.) are complete before beginning the update operation. My default max limit is acually unlimited right now when I run launchctl limit maxfiles but I'm going to err on the side of sticking to the instructions provided from basho.*Please note the following restrictions when using this software. The gist this was forked from set the macproc to 2048 which is lower than my current default 10240, so I'm not going to modify that for now. I'm no expert on this stuff, but maybe it sounds reasonable to you too.ฤก2288-2048=10240 (soft limit) (Oh hey what do you know - this is the same number as the kern.maxfilesperproc). For a soft limit, I think subtracting 2048 seems fair also. This seems like a fair max limit given my minimal research on this issue. I would presume this might be the kernels max capacity (probably guesstimated by apple, but still, I have to respect apple's settings). How I modified limits for my 2013 Macbook air (running sierra): run sysctl -a | grep kern.maxfiles this may show you: kern.maxfiles: 12288 If your system is configured correctly, you should see that maxfiles has been set to 200000. At this point, you can restart your computer and enter ulimit -n into your terminal. Like the plist files, your bashrc or similar file should have -rw-r-r- permissions. In addition to setting these limits at the system level, we recommend setting the at the session level as well by appending the following lines to your bashrc, bashprofile, or analogous file: While the steps explained above will cause system-wide open file limits to be correctly set upon restart, you can apply them manually by running launchctl limit. This permissions should be in place by default, but you can ensure that they are in place by running sudo chmod 644. Both plist files must be owned by root:wheel and have permissions -rw-r-r.
