How to re-combine and unzip a multi-part split ZIP file

1. Open the Terminal.app from Applications » Utilities
2. Use the following command, adjusted to your needs and ZIP-file location(s):

zip -s 0 ~/Downloads/splitted-zip.zip --out ~/Desktop/singlefile-filename.zip

3. Once you have created the single ZIP-file, use the following command to unzip it (again, adjust to your needs):

unzip ~/Desktop/singlefile-filename.zip

However, if you are dealing with a set of zip files that do not include numbered file extensions (foo.z01, foo.z02, etc) and are simply multiple zip files that should be unarchived together into the same directory (such as a split Google Drive zip archive download: foo-001.zip foo-002.zip etc.), the following should work:

unzip '*.zip' -d /path/to/unzip/destination

How to convert (remux) video files from mkv to mp4

  1. Lauch OBS https://obsproject.com/es/download
  2. Open “File” –> Select “Remux Recordings”
  3. In the left panel, select the .mkv file you want to convert to .mp4 and in the right one set the destination
  4. Click on “Remux”

Otherwise, if you haven’t created the video files yet you can select the automatic remux option in OBS:

  1. Open “Settings”
  2. Go to “Advanced”
  3. In the “Recording” section tick the “Automatic Remux to mp4” option

Now you can use your footage in Premiere Pro and Adobe Media Encoder.

Here’s an article on how to use OBS with Zoom. Caution, it’s bleeding edge at this point and not quite production ready…

Code

Workaround for code signing in MacOs 10.15.3 Catalina

APPLICATION=/Applications/zoom.us.app && codesign -d --entitlements :- $APPLICATION | { xml2; echo "/plist/dict/key=com.apple.security.cs.disable-library-validation"; echo "/plist/dict/true"; } | 2xml > entitlements.xml && sudo codesign --sign - $APPLICATION --force --preserve-metadata=identifier,resource-rules,flags --entitlements=entitlements.xml && rm entitlements.xml

Tip: you’ll need to re-authorize mic/webcam/screensharing in Zoom after re-signing the code. So don’t forget to run through a test meeting first to make sure everything is working before going into an important meeting.
