Updating the iCarsoft POR OBD tool using a Mac?
THIS IS NOT A HOWTO ARTICLE. THIS IS A HINT FOR EXPERIENCED USERS. USE AT YOUR OWN RISK.
Yep, you’ve read that correctly. You can update the iCarsoft firmware using a Mac. The key is to use Wine, the compatibility layer for Mac hardware that lets you run Windows apps. You can then use Wineskin PortingKit or CrossOver to wrap up the runtime environment into an icon that looks like a Mac app that you can launch by double-clicking on it. You will want PortingKit or CrossOver to run the iCarsoft update app in 32-bit, because modern MacOS is 64-bit and making Wine run in 32-bit without a wrapper is a hassle.
Once you make those wrappers, you might want to change the boring default icons. You can use

Is TurboTax still telling you “It Looks Like We Hit A Snag”?
If your TurboTax for Mac is still telling you “It Looks Like We Hit A Snag” after an initial crash AND sending in the error report EVERY TIME you start TurboTax, then you have to clear TurboTax’s instance from the cache for KSCrash.
If you’ve had the situation outlined in: https://discussions.apple.com/thread/253681263?
… but ended up with Step 5 like @Williamfromroswell did, where TurboTax shows that pesky error report window every time you restart, then the one last place you have to look is:
~/Library/Caches/KSCrash/TurboTax
Quit TurboTax and move this folder to the Trash. When you start TurboTax again, it should not show you the error report screen until the next time TurboTax actually crashes.

What’s with these weak-ass DC garage door motors these days?
If you’re DC motor garage door opener seems weak, either your door is too heavy or the springs are past half their life. Be prepared to shell out some dough.
If you’ve been in the market for a garage door opener in the past 5 years or so, you may have noticed the switch from AC motors to DC motors. Manufacturers like Chamberlain (Liftmaster/Craftsman) market the DC motor openers as “Ultra-Quiet” versus just “Quiet” of the old.
The 2018 California SB 969 mandates that new garage door openers are available with battery backup – that necessitates the motors to work on DC power off of a battery. The rest of the country gets to enjoy the benefits and pitfalls of this new device at their own leisure.
Yes, DC motors are quiet, especially if they are paired with a belt drive instead of the traditional chain drive mechanism. No clanking, no buzzing, no thunk at the start and end of the cycle. The AC/DC inverter (transformer) quietly supplies constant steady power to the drive system.
But because it doesn’t draw its power directly from the house’s AC circuit, it will not answer to demand. That means, if the the springs on the door gets old and weak, you’ll notice the door slow down. If you’re an installer, you’ll also find out the hard way that the motor will not be able to assist you when lifting the door under a broken spring.
This is not because the motor itself is weak. It is because the motor is not allowed to draw more current from the house because there’s a DC inverter playing gatekeeper. It is in theory a safety mechanism that prevents problematic doors from being lifted and then falling on a person. The controller board should register an error and cease to function until the problem is remedied.
Unfortunately there is an unintended effect. In case of a broken spring, the door will move a smidge under extreme load and damage the motor control unit – not the physical motor, but a small gearbox and circuit board attached to the motor.
In an effort to make safer more quieter garage door openers, manufacturers have complicated the design of these units and made it more difficult to diagnose and fix. Fortunately, we have the internet, so we can sit at a desk and search instead of tinkering with the greasy innards of the garage door motor.
The easiest solution for manufacturers would probably be to increase the motor current to 24V and put two 12V batteries in there…

That Mac script that passes MP4v to ffmpeg
Because of how Mac OS Mojave, Big Sur, Monterey handles file permissions, many Firefox add-ons are not able to pass downloaded files to outside binaries. Usually, the add-on will return a “file/directory not found” or “permission” error.
I use one such add-on that converts movies to audio-only so that I can listen to a video in a car. After the upgrade to Mojave, the add-on started having problems with passing the downloaded MP4 file to ffmpeg to convert into M4A (MP4 Audio). So instead of typing commands into the Terminal to pass the file to ffmpeg, I decided to make an Automator script to convert MP4 to M4A from contextual menu by right-clicking on the file
- In Automator create a new Quick Action
- Make the item shown below. I usually keep the ffmpeg executable in ~/bin
- Save the script
- Name it Convert MP4 to M4A
That’s it. Now you can right click on a MP4 file and call up the conversion script from the Quick Action or Services item.
This script is meant for people who know what they’re doing. It won’t check if the file you’re trying to convert is an actual MP4 file, and it won’t display any errors to the GUI. Use with caution.

How do I unlink my Facebook account from the McDonalds mobile app?
Short answer: At the time of this article (Dec 2021) YOU CANNOT.
You can’t even change your e-mail address with the McDonalds app even if you signed up using your e-mail address only.
According to the official McDonalds Mobile Order app help page: https://www.mcdonalds.com/us/en-us/mcdonalds-app/faqen.html
I suspect that the developers for McD decided to use the e-mail/login-method as the primary unique key for each user instead of assigning a number for the userID. Kind of ridiculous. If you get fired from work or graduate from school, your e-mail address is going to change. If you move from Meta to Google, your login method is going to change. McDonalds expects each customer to possess a “for-life” e-mail address to be using the mobile app.
I hope this changes in the future because it is totally do-able technically and makes sense practically.
