#macOS has a security feature called quarantine. If you download an archive with a web browser the file will get the com.apple.quarantine attribute added to it. Extracting the archive with Finder will ensure that all the extracted files will inherit this attribute, too. If you try to execute an unsigned program, executable or script with the attribute you will get a warning and are unable to execute it. Generally this is a good feature to have since it ensures that you don't accidentally execute malicious code or programs downloaded from the internet.

However, this can be somewhat annoying if you know the application archive is "safe", while not signed by #Apple.

There are two approaches to fixing this:

1. Remove the quarantine attribute before extracting the archive: xattr -d com.apple.quarantine /path/to/file and then extract

2. If you have already extracted the archive you can: find /path/to/dir -type f -exec xattr -d com.apple.quarantine {} \;

WARNING: You're to perform due diligence to ensure you only do this on files you trust and have verified to be safe. This knife is sharp so watch your fingers. #tips

I wrote a #matrix digital rain implementation in under 50 lines of pure Bash.. I chose Bash due to it being widely installed and extremely portable. With modern systems this shouldn't cause any noticable performance changes and seems more than efficent so far

Looking for feedback, contributions or whatever helps 😆. If it interest you at all, let me know what you think about it!

Do you, or have you ever, used a graphical user interface? If you use #Windows, #macOS, or any version of #Linux with a window manager or desktop environment, you can thank Dr. Clarence "Skip" Ellis.

Dr. Ellis worked at Xerox PARC, the research organization that developed the modern GUI. Icons, windows, the mouse, Ethernet-based networking, laser printing - all of these (and more) came out of PARC. Dr. Ellis led the team that created Officetalk, the first program to use icons and the Internet. He got his start at 15 years old showing a local tech company how to reuse punch cards, which was a game-changer back in 1958.

Oh, and he was also the first black man to earn a PhD in Computer Science.

Apple just updated the support page about iCloud Keychain and removed the part that says when keychain data is deleted from Apple servers. This means if #iOS17, #iPadOS17, or #macOS 14 has turned syncing on without your permission, it's a hassle to make sure data is deleted from #Apple servers.

Our investigation and testing showed that upgrading to Apple's latest operating systems switch iCloud Keychain on without user permission. The number of users experiencing this issue is growing 👇:
