Black background on Safari after dark

[Mikeo512]

After dark the background screen on Safari (MPB 15.0) goes black. How can I stop this and revert to a light background?

 

[MightyGem]

Go into System Prefs>General. It sounds like you have the Appearance set to Auto, which will do what are seeing. Just select Light.

 

[Mikeo512]

Thank you ... just done that.
But will need to wait to cfm because it's still morning here.

Note: this only applies to transitional wallpapers signified with a little circular icon half Dark an half Light. The others will remain the same unless you enable "Night Shift" which is system wide.

 

[Mikeo512]

Thanks to everyone ... the black screen has gone away.

But will need to wait to cfm...

??? cfm ?

confirm, I guess

 

[Mikeo512]

Yes, the black background has been banished.
Many thanks for the help.

As for "cfm" .... that is indeed (a Morse code) abbreviation for "confirm". In a former life, I was a radio officer in the Merchant Navy ... still dream in Morse! BTW, in British English, the radio officer is known as "Sparks" ... but in Italian and some other languages, he is unofficially the "Marconista" or just "Marconi". "Sparks" is also used in the building trade for "electrician" ... like "brickie" (bricklayer) and "chippy" (carpenter).

Thanks M, I never did Master Morse code but I certainly admire those who did.

I don't do much with Facebook type code either when some use all kinds of strange abbreviations as if it's a new language which I guess it is.

I never did Pig Latin either which was very popular at some schools.

File that as one of the many things I did not know. You learn something new every day.

Not even Apple's macOS Dictionary seems to know that interesting fact as there is no mention of that abbreviation linking anything to do with Morse code.

It's not actually part of Morse Code. It is a convention used by Morse operators to shorten the number of letters transmitted to convey the message. Ham radio operators (I am one) use similar shorthand codes, starting with "Q" to do the same. For example QRT is "I am shutting down this station." Plus, there are also shorthand number combinations for greetings. "73" for example is "goodbye and good wishes."

OMG I understood most of that but you guys are giving me the itch to start that. If I bring any moew junk into the house Mrs. Slydude is going to scream.

Remember that messages would be sent in Morse code. Back in 1950s and 1960 (and earlier) the short waves were full of Morse code. Ships and coast stations were active on the 4 mc/s, 6 mc/s, 8 m/cs, 12 mc/s, 16 mc/s and 22 mc/s bands. Coast stations such as FFL (France), DAN (Germany), IAR (Italy) and so on would run Morse code on continuous tapes. These were so-called 'traffic lists' with the callsigns (4-lettters) of ships for whom they had 'traffic' (messages). These were sent at speeds of about 20 words per minute but repeated over and over again. I taught myself Morse by listening to these tapes. At first, when you were learning, you would write everything down on paper but as you progressed you will be able to understand everything in your head.

I was in the Boy Scouts in the mid-1970s and they had a merit badge which dealt with Ham radio IIRC. I was kinda interested in that at the time but had no good way to set up a Ham radio at the residential school I attended. At the time I think the Ham license required demonstrating basic Morse skills.

 

[Mikeo512]

Yes, it was a requirement to know Morse if you wanted to operate on the amateur HF bands (short wave). But not if you agreed to use VHF and UHF only. The reason for this goes way back ... in earlier times, ships and aircraft in distress would first call (in Morse) on their usual frequencies or on the designated distress frequency of 500 kc/s. (There was also a distress frequency in the middle of the 8 mc/s calling band for ships.) If they got no response, and as a last resort, the procedure was to put out an SOS on one of the ham bands. That was why amateurs were required to pass a proficiency test at 12 w.p.m. Someone might send you an SOS. (Doubt this rarely, if ever, happened in reality) ... but that's why the Morse requirement remained in force until all ships and aircraft had the new emergency (satellite) distress equipment. As far as sending and receiving speeds were concerned, the speed for a 2nd Class maritime op was 20 w.p.m. and for a 1st Class maritime op it was 25 w.p.m. But Morse was also used for point-to-point communications on land. Some of these ops were red hot. I remember at college when I was preparing my Maritime certificates, there was a Nigerian ... a former point-to-point op ... on our course. He could send (on a straight key) at 40 w.p.m. and receive at the same speed. He could write it all down with a pencil!

Wow! 40 WPM is really quick. I got to 20WPM, max. Another reason for using Morse is that it takes a lot less power to communicate because the signal is simple on/off and not modulated. So, if there is an emergency, your battery or generator will not have as high a load if you used Morse.

I remember going into my Father in law's shack and hearing nothing but static. But he was working a station in Italy, and as conditions decayed over time, the two kept going because they could still make out the signal in the noise. To a newcomer, like me, it was just static, but they were communicating. I think they were close to 35wpm. Amazing!

I did mostly SSB, 40 and 20, plus 2m/440 FM mobile. But I moved houses about 15 years ago and just never got a good solution for an antenna here. My location is not good, with a hill directly behind me blocking the sky for anything low, plus I am near an airport, so going high is not reasonable. Never got it sorted out, so the rig is in storage.

Still licensed, though. It was my father in law's license originally. He was on air before the FCC existed, was licensed as "HRE" as a teen by the Federal Radio Commission, the predecessor to the FCC, in the '20's. Then when the current callsign setup was negotiated, they issued him the W1HRE. He was in the US Army in WWII in the Signal Corps in Africa and Italy, later in France and Germany. When they opened up Vanity callsigns, he applied for, and got, the original callsign. When he died, I applied for it and was granted it. So HRE or W1HRE has been (semi) active for almost 100 years. I should look up the specific date of his first license and QSO and see if I can get something on the air on the centennial date.

Speaking of WPM would you believe that according to a BBC article I just read the average speed typing on a mobile phone touchscreen keyboard is now 38 WPM and the fastest out of 37,000 people surveyed was 85 WPM. Touchscreen typing speeds close in on keyboard rates

I daren't test myself, I probably hit around 10-20 but then I use punctuation
