I am always in need of a certain command or utility and end up searching the Internet for a solution. I’ve gotten tired of it and am starting to collect useful commands and utilities here so that I can easily find them. Of course that means anyone else can find them as well.
macOS Wireless Network Roaming
Mac OS Show All Files (including dot files) in Finder

FreeBSD set system Timezone
There are a number of write ups on the Internet about making links to various system timezone control files, and while I like knowing what is going on under the covers, there is a much simpler way. The utility that is used at system installation time to set the timezone can be run at any time to set the system timezone, tzsetup.
2011 MacBook Pro Graphics Failure
My 2011 MacBook Pro has the dreaded discrete graphics failure. The best description of the failure (and the fix) is here. I now have two bootable partitions on that machine, one has the kernel extensions for the discrete graphics removed and I use it only to fix the NVRAM and main partition after doing an OS update. It is running High Sierra (10.13) latest and runs great except for the graphics, but I don’t use it for heavy graphics work anyway.
