macos – Bring OS X Error Message window to the front – Super User

Posted by jpluimers on 2020/10/19

Short answer based on WayBack macos – Bring OS X Error Message window to the front – Super User

The GUI way

  1. Press Command+Space to start Spotlight Search
  2. Search for /System/Library/CoreServices/Problem Reporter.app and wait for the result to show up
    (a search for just Problem Reporter.app will not reveal it!)
  3. Press Enter
  4. Now the System Reporter windows is in the front and has focus

The Terminal way

  1. Open a Terminal window or tab
  2. Run open -a /System/Library/CoreServices/Problem\ Reporter.app
  3. Now the “Problem Reporter” windows is in the front and has focus

How to remove all old and outdated brew packages on MacOS – nixCraft

Posted by jpluimers on 2020/10/19

I was not aware that brew install,  brew cask install, brew update and brew upgrade would keep all the older versions on disk, so I was a bit amazed that OmniDiskSweeper and GrandPerspective found over 20 gigabytes of cruft in /usr/local/Cellar and a bit in /Library/Caches/Homebrew.

Based on [WayBack] How to remove all old and outdated brew packages on MacOS – nixCraft and [WayBack] homebrew – brew: how to delete outdated version of package – Ask Different (which have more info) I changed the order a bit:

alias brew-cleanup-update-ugprade='brew cleanup && brew update && brew upgrade'

You can use brew pin to keep specific versions (and brew unpin to release them so you get the most recent one).

The main reason people do not bump into brew cleanup is that it is not advertised as a command:

# brew --help
Example usage:
  brew search [TEXT|/REGEX/]
  brew info [FORMULA...]
  brew install FORMULA...
  brew update
  brew upgrade [FORMULA...]
  brew uninstall FORMULA...
  brew list [FORMULA...]

Troubleshooting:
  brew config
  brew doctor
  brew install --verbose --debug FORMULA

Contributing:
  brew create [URL [--no-fetch]]
  brew edit [FORMULA...]

Further help:
  brew commands
  brew help [COMMAND]
  man brew
  https://docs.brew.sh

But it is there and has help as well:

# brew cleanup --help
brew cleanup [--prune=days] [--dry-run] [-s] [formulae|casks]:
    Remove stale lock files and outdated downloads for formulae and casks,
    and remove old versions of installed formulae. If arguments are specified,
    only do this for the specified formulae and casks.

    If --prune=days is specified, remove all cache files older than days.

    If --dry-run or -n is passed, show what would be removed, but do not
    actually remove anything.

    If -s is passed, scrub the cache, including downloads for even the latest
    versions. Note downloads for any installed formula or cask will still not
    be deleted. If you want to delete those too: rm -rf "$(brew --cache)"

On pin and unpin:

# brew pin --help
Usage: brew pin formulae

Pin the specified formulae, preventing them from being upgraded when
issuing the brew upgrade formulae command. See also unpin.

    -d, --debug                      Display any debugging information.
    -h, --help                       Show this message.

# brew unpin --help
Usage: brew unpin formulae

Unpin formulae, allowing them to be upgraded by brew upgrade formulae.
See also pin.

    -v, --verbose                    Make some output more verbose.
    -d, --debug                      Display any debugging information.
    -h, --help                       Show this message.

Viewing a USB WebCam on Windows 10 without any fuzz

Posted by jpluimers on 2020/09/28

Windows 10 comes with a broken Camera viewer and before that, Windows 7 killed the one in Windows XP.

On a Mac you have the open source Quick Camera (which named QCamera before, seeViewing an USB camera on Mac OS X without mirroring and Capturing from a Magewell XI100USB on a Mac using OS X) at [WayBack] GitHub – simonguest/quick-camera.

For Windows 7, a long search initially revealed a lot of bloat-ware, but finally ended to these two both from the same author:

It is not open source (yet?), but since it is .NET, it is reasonable easy to see the innards.

Like QCamera, it does not require installation: just unzip and run. Enjoy!

Yes, I know there are Windows 10 workaround steps via Microsoft.CameraApp.App.ctor, but if you look at [WayBack] Win10 Home N – Camera App fails: System.IO.FileNotFoundException – Microsoft Community you will understand I did not apply them.

Similarly, when you install Skype from the app store, then sign-in, it will tell you that Skype is out of date.

Need to figure out how to remount 2015 Retina MacBook Pro SD card that got ejected during sleep

Posted by jpluimers on 2020/09/04

Somehow, every now and then, a 2015 Retina MacBook Pro will eject the SD Card during sleep.

I’m not sure about the cause, just about the message that a drive got unmounted in an unexpected way.

This fails to rescan for the drive on Mac OS Sierra:

sudo kextunload -b com.apple.driver.AppleSDXC
sudo kextload -b com.apple.driver.AppleSDXC

As per [WayBack] external disk – Problem with kextunload SD card remount – Ask Different, I tried the kextstat below, however, before the unload/load statements, kextstat | grep -e SDXC returns nothing.

After them, it returns something like

156 0 0xffffff7f841f3000 0x12000 0x12000 com.apple.driver.AppleSDXC (1.7.6) 0F6F5025-A1C4-3E77-9ECD-4D4410E684C5 <16 15 12 5 4 3 1>

When it happens again, I will likely need to read these:

It might be that somewhere along the line, SDSX is not started by default any more or not applicable to MicroSD to SDXC card converters. These screenshots at least show that this disk is connected via a USB path:

The screenshots are from the stock “System Information.app” tool, and I really wish it showed the kext drivers used for each device. That would make debugging these issues a lot easier!

A solution then could be as easy as this:

Unmount all USB connected devices (for instance with a command like diskutil eject disk1);

sudo kextunload -b com.apple.driver.AppleUSBCardReader
sudo kextload -b com.apple.driver.AppleUSBCardReader

However my first try got me an error similar to the one result [WayBack] External USB disk sometimes requires a reboot to be recognized after eject – Ars Technica OpenForum I found after searching for “class com_apple_driver_AppleUSBCardReaderDriverNub has” “instances.”:

7/28/16 10:05:54.000 AM kernel[0]: Can't unload kext com.apple.driver.AppleUSBCardReader; classes have instances:
7/28/16 10:05:54.000 AM kernel[0]: Kext com.apple.driver.AppleUSBCardReader class com_apple_driver_AppleUSBCardReaderDriverNub has 2 instances.

MacOS/OS X/Mac OS X: Keeping an eye on your used disk space

Posted by jpluimers on 2020/07/06

Two tools I like:

GrandPersctive is good at showing a visual overeview. OmniDiskSweeper is better at gradually drilling down.

Easy installation:

$ brew install caskroom/cask/omnidisksweeper

$ brew install caskroom/cask/grandperspective

MacOS/OS X/ Mac OS X tip: AppCleaner

Posted by jpluimers on 2020/07/03

[WayBack] AppCleaner helped me get rid of a the gazillion number of versions that GoToMeeting had silently installed and their dependencies.

Gigabytes recovered.

Installing is easy: $ brew install caskroom/cask/appcleaner

AppCleaner is a small application which allows you to thoroughly uninstall unwanted apps.

Installing an application distributes many files throughout your System using space of your Hard Drive unnecessarily.
AppCleaner finds all these small files and safely deletes them.

Simply drop an application onto the AppCleaner window. It will find for the related files and you can delete them by clicking the delete button.

Tools I use for audio/video downloading, media conversion and audio editing

Posted by jpluimers on 2020/07/03

A friend asked me what tools I use for downloading media, converting it to various formats (including audio extraction) and audio editing.

It is a surprisingly short list:

Most of it runs out of the box on Mac OS X/MacOS/OS X, as I’ve moved there form Windows for most of my day to day access to systems (there is a great set of Microsoft Remote Desktop in the app store: [Archive.is] Microsoft Remote Desktop 8.0 on the Mac App Store and [Archive.is] Microsoft Remote Desktop 10 on the Mac App Store; I like the first one better).

Audacity shortcuts

Audacity error when starting “The application “Audacity.app” can’t be opened.”

Posted by jpluimers on 2020/06/29

For quite a while, I had the error “The application “Audacity.app” can’t be opened.” and Audacity still opening. Clicking the OK button often enough made me hunt for the solution:

This is what I did:

$ cd ~/Library/Application\ Support/audacity
$ grep Temp audacity.cfg
TempDir=/Users/jeroenp/Library/Application Support/audacity/SessionData

Then I checked if the directory existed:

Is there a button in iTunes to say “Stop after playing this song”? – Ask Different

Posted by jpluimers on 2020/06/26

Put the song in a playlist and click the check box off. All the songs in the playlist will have to be clicked off as well.Or easier still have the track as the only song in the play list.

For me, the easiest way to do this is to put all songs in a playlist, then in the playlist (can be “Playlist” view mode, but “Songs” view mode is easier). The video below shows exactly how to do this, but here are te steps:

  1. select all songs with Command-A
  2. right-click
  3. choose “Uncheck Selection” to remove all checkboxes
  4. double click on each song you want to play individually

Via:

Finally, [WayBack] iTunes 11 for Mac: Ways to play songs shows the meaning of the shuffle and repeat buttons in the player:
