Often I need to generate passwords or uuids (on some systems called guids). I usually try to do that in a relatively platform agnostic way as I use MacOS, Windows and Linux in various mixes for many reasons (for instance that I have had developed quite hefty RSI in the early 1990s of the and the best keyboard/pointing-device combination for is the MacBook built in keyboard/touchpad combination so basically MacBooks are my window to all other operating systems).
Generating randomly with a good random number generator them makes sense as for most usage, it is important that both passwords and uuids are hard to guess which means having an entropy that is as high as possible.
A cool thing about OpenSSL is that:
- most of not all systems have it installed (it was no coincidence I published Installing OpenSSL on Windows a few days ago)
- it has a very good pseudo-random number generator and as of [Wayback/Archive] OpenSSL version 1.1.1 first released in 2018 has solved the problem around [Wayback/Archive] Random fork-safety – OpenSSLWiki, see [Wayback/Archive] Our Review of the OpenSSL 1.1.1 Random Number Generation Update – OSTIF.org.
- it supports various useful output formats
hex (hexadecimal) and base64 (next to the default of octet – or by today’s naming convention byte – output)
The easiest to generate are passwords. Yes I know that password managers can do this too, but there are some systems I cannot use them on or sync between them (don’t you love the corporate world) so my aim is to use a random password generator in a platform agnostic way which usage is easy to remember.

This still works for Apple Silicon based Macs: [Wayback/Archive] How can I tell what wattage my MacBook Pr… – Apple Community
TL;DR:
- Either:
- ⌘-space -> System Information.app
- menu -> About This Mac -> More Info… -> System Report…
Note that “System Report…” starts the “System Information.app” (how cool would naming consistency be…)
- Hardware -> Power
- Browse down to “AC Charger Information”
On my M1 MacBook Pro, the values depend on the charging ports used:

It took me a few queries to find the correct online solution for this problem: after adding a TrueType (and it’s extension: OpenType) font using the built-in MacOS Font Book, they do not show up in Pages or Preview, not even after validating the fonts in Font Book.
Solutions:
- reboot (found this out myself)
- killing the fontd font daemon from the Activity Monitor
- restart font daemon (found out via the link below)
launchctl kickstart -k gui/`id -u`/com.apple.xtyped
The last one does not work on my Apple Silicon machine, the first two work fine.
For Preview, you have to Force Quit it then start it (so it re-opens all the previous files) to take effect.
I needed this, because I

n modern versions of Mac OS, like macOS Mojave, Catalina, Sierra, OS X El Capitan, and Yosemite, you can shorten the syntax considerably as so:
defaults read /Library/Preferences/SystemConfiguration/com.apple.airport.preferences |grep SSIDString
In prior versions of Mac OS X, you can opt for the same as the above command, or use the lengthier string below with heavy regex:

When I have an external monitor connected to my 2015 era Retina MacBook Pro machines, I wanted some apps to appear on the laptop screen and others on the external one.
That was harder than I hoped for as no single solution works in all cases.
What I do now is to make sure the icon bar is on the monitor where I want applications to open. Not perfect, but works for most cases.
Here are some links that helped me:

TL;DR: it is impossible on a Mac to accurately measure power usage by attached USB devices. Only a general indication is possible, but it is unreliable.
[Wayback/Archive] How to monitor USB power consumption? – Ask Different
- System Profiler needs manual refresh and is a very rough indication
- iStatMenus is a graph, but not very accurate
- Activity Monitor is even rougher than the above

On my M1 MacBook, somehow Spotlight started to fail returning some indexed files (especially recently added ones would not show up or it would take a very long while for some of them to show up).
So I revisited mdutil and related commands while writing a comment on the YouTube movie [Wayback/Archive] How To Rebuild the Spotlight Index on Your Mac – YouTube which since then vanished, but luckily I saved it and here I amended it with formatting:
