3.5mm headphone jack to Optical audio (TO… - Apple Community
I have a macbook pro from 2010. Before I buy one I was wondering if I can use a 3.5mm (headphones jack) to optical audio cable (Toslink) to have sound from my macbook pro run through my surround sound system? Anyone know if this works? My surround sound system definitely has the optical audio input.

How to possibly fix a PC that will turn on but will not beep and will not display anything on screen - YouTube
Do what the video shows: Disconnect the power cable, remove the CMOS battery, short the CMOS jumper pins for 9 seconds then return the jumper cap to its initial position (only if you can find these jumper pins; if not, skip this step), press your PC's chassis power button switch (to discharge any remaining power circulating in the system), leave the PC unplugged and in this state overnight, then the next day return the CMOS battery to its socket, power up the PC, and if no beep, then disconnect the power cable, press your PC's chassis power button switch (to discharge any remaining power circulating in the system), remove one component, power up the PC, and if no beep then repeat (each time unplugging the PC, pressing the power switch to discharge remaining power, removing a remaining component, and then powering up, and this until the PC beeps at boot).If it never beeps, even when you are down to just motherboard, power supply & CPU+fan, one of these remaining components may be bad

MacBook Air (2018) review: Testing the 1.6GHz dual-core Core i5 laptop | Macworld
One of the things we loved about the MacBook Air was the MagSafe charging connector. USB-C charging is convenient in a “you only need one cord” sort of way, but there is almost no old-school Mac laptop user that doesn’t have a dozen stories about how the magnetic breakaway charger saved it from certain doom when someone tripped over the power cord.

The New MacBook Air Has a Looming Reliability Issue
The MacBook Air is held in high regard for being a well-built laptop that lasts forever. And since the Air has lasted so long, many users (including most of my relatives) have held onto their older models. These systems still work, but they’re finally starting to show their age, leaving their owners looking for a new laptop.

Apple iPad Pro review 2018: the fastest iPad is still an iPad - The Verge |
Apple seems to want it both ways with the iPad Pro: it loves to tout the iPad’s laptop-dwarfing sales figures and industry-leading performance, but when pushed on the iPad’s limitations, the company insists that the iPad is still an ongoing attempt to build the future of computing, not a laptop replacement.

But after eight years, this double-sided argument is no longer tenable. Unlike virtually every other computer, the iPad is a product of Apple’s singular vision: the company designs the display, the processor, the operating system, and the limits of the applications and accessories that plug into it. And after all this time, it’s clear that whatever roadblocks and frustrations exist in using the iPad Pro are there because Apple wants them there. There just aren’t that many excuses left.

bash - How to obtain the number of CPUs/cores in Linux from the command line? - Stack Overflow |

Processing the contents of /proc/cpuinfo is needlessly baroque. Use nproc which is part of coreutils, so it should be available on most Linux installs.

Command nproc prints the number of processing units available to the current process, which may be less than the number of online processors.

To find the number of all installed cores/processors use nproc --all

On my 8-core machine:
<code class="language-bash">$ nproc --all

Throttlegate | Low End Mac |
If Apple had added a feature that put up a warning dialog box when a battery was nearly consumed that gave the user an option to either keep the unit in full power mode (with the expectation that unexpected shutdowns could occur) or reduced power mode (to minimize the risk of unexpected shutdowns), I wouldn’t have any issues and I wouldn’t be writing this article. They could have also easily added a dialog box with an option to contact AppleCare or make an appointment at a local Apple Store to have their battery replaced. But I guess that is just too much to ask from the powers that be at Apple HQ in Cupertino.

Low End Mac’s Compleat* Guide to the MacBook Air | Low End Mac |
Apple has stopped selling the 11″ Air – the 13″ model remains for sale, but with minimal upgrades and – in particular – a screen resolution that was good in 2010 but is now a bit of an embarrassment. Continued sales are a testament to the quality and value of its now 8-year old design, but I wonder how much longer it will remain in production?

Wireless Desktop 1000 in Mac OS X 10.6: Mouse scroll wheel not working...
After a few times I went to exchange a new mouse thinking it's the Mouse's problem. However with the new mouse this still happens... I still have to take out then insert the battery to get the scrolling to work right after using the mouse for a few hours... Anyone have tips? Do you think it's my receiver? Thanks!

Why won't Apple make a touch screen laptop and iMac in combination with also keeping the trackpad, mouse, and keyboard? - Quora
Several of us retrofit third party touch screen interfaces onto a number of iMacs. The experience wasn't very satisfying, unless you set the software driver to do a combined "move here + click". Even then, you ended up with finger grease all over the thing, which significantly detracted from its utility for GUI and design work, and it was really annoying when pointing things out in terminal windows, and so on. Overall, it was not that useful, and only two of the 5 of us who had hacked up their iMacs left the touch screen enabled.

Again, this was the same reason given by the UX people.

The only surprising thing was the lack of a Bluetooth keyboard with a touchpad that was always in the same location relative to the spacebar, to give a laptop-like experience. I saw several people attempting to use third party versions of these things, with little luck. The problem came down to the ability to use the touchpad area without relocating your fingers away from their default locations for touch typing. Something which is easy with a keyboard the size of a small laptop keyboard, but much more difficult with a full size keyboard, even if you omit the numeric keypad in the design.

And yet again, the same reason for not supporting it that was given by the UX people.

Don't think that these things have not been tried out internally, or using UX labs and having people actually use prototype equipment that has the features; they almost certainly have for everything you could think might be a good idea to add to an iMac or MacBook.

Why don't MacBooks have two screens, one being a touch screen on the back not just for you but also for strangers? - Quora
There are various reasons. Here's some:

The lid would have to be thicker and Jony would throw a fit.
It would look silly and Jony would throw a second fit.
It would weigh more and Jony would throw a third fit.
It would cost more and Tim Cook would throw a fit.
It would be feature creep and checklist design, at which point Steve would rise up from beyond and smite whichever engineer and designer was responsible for such a travesty.
You are already carrying around a small touch screen in the iPhone - why replicate it attached to your laptop.
It would burn battery.
It would only be useful to you when the laptop was out of its case yet closed. A tiny amount of the time.
