Issue Description

After use in Xcode, the iOS simulator on macOS occasionally leaves behind mounted disk images that become unresponsive and cannot be unmounted through standard methods. This can lead to cluttered disk space and potential conflicts with future simulator sessions.

• Screenshots of the issue:

In the example above, it was observed that certain simulator disk images, such as disk5s1 and disk7s1, remained mounted but unresponsive. When attempting to unmount these volumes using Disk Utility, it always prompted saying the volume was in use, even after quitting Xcode and all related processes (the CoreSimulator related processes always reappeared after being killed).

  2466 : 1762759121:0;locale
  2467 : 1762759501:0;echo "ä½<83><80>好"
  2468 : 1762759519:0;echo "ã<81><83>³ã<82><83>³ã<81>«ã<81><83><81>ã<81>¯"

Issue Description

During the Beta testing of the new iPadOS 26, I accidentally deleted all albums in my iCloud Photos Library on my iPad, which then synced the deletion to my other Apple devices.

Issue Description

When using mpv to play videos from Bilibili, users may encounter issues where mpv fails to pass cookies to yt-dlp correctly, regardless of whether the cookies are already in Netscape format, leading to error messages like the following:

→ mpv --cookies-file="~/bilibili_cookies.txt" --ytdl-raw-options=format=100028+30280 https://www.bilibili.com/video/BV1HMH7z4ES4
[ytdl_hook] ERROR: [BiliBili] BV1HMH7z4ES4: Requested format is not available. Use --list-formats for a list of available formats
[ytdl_hook] youtube-dl failed: unexpected error occurred
Failed to recognize file format.

The format 100028+30280 is a valid format on Bilibili, but only extractable when the user is logged in, which requires the correct cookies to be passed to yt-dlp, which is the default backend for mpv to handle online video playback.
