Which of my apps are compatible with Big Sur?

These are still early days in my testing with the first beta-release of macOS 11 Big Sur, but here’s a list of my free apps which I believe to be compatible. I will continue to test and to update this page with further information.

  • Apfelstrudel 1.3 – works fully.
  • ArchiChect 2.3 – appears to work fully; 2.3u is a Universal version with specific support for Apple Silicon.
  • Bailiff 1.4 – appears to work fully.
  • Cirrus 1.9 – appears to work fully, including its browser, log browser, and iCloud upload test; 1.9u is a Universal version with specific support for Apple Silicon.
  • Consolation 3.9 – appears to work fully, although I haven’t yet tested all its features, and haven’t checked to see whether Big Sur adds further fields; 3.9u is a Universal version with specific support for Apple Silicon.
  • DelightEd 2.0b4 – appears to work fully. QuickLook still doesn’t display its document thumbnails correctly, though. Version 2.0b4u is a Universal version which runs native on both architectures.
  • Dintch 1.2u is a Universal version with specific support for Apple Silicon.
  • Dystextia 1.6 – works fully.
  • Fintch 1.1 – works fully; 1.1u is a Universal version with specific support for Apple Silicon.
  • LockRattler 4.25 – believed to support Big Sur fully. Version 4.25u is a Universal App specifically adapted for Apple Silicon.
  • Nalaprop 1.0b10 – appears to work fully.
  • PermissionScanner 1.7 – appears to work fully.
  • Podofyllin 1.0b17 – appears to work fully, and thumbnails work properly too; 1.0b18u is a Universal version with specific support for Apple Silicon.
  • Precize 1.9 – appears to work fully, including bookmarks; 1.9u is a Universal version with specific support for Apple Silicon.
  • Revisionist 1.7u is a Universal App with specific support for Apple Silicon.
  • Rosettavert 1.4 – appears to work fully.
  • SilentKnight 1.8 – Big Sur now fully supported. On Apple Silicon, use the Universal version 1.8u, as the Intel version will crash repeatably.
  • Spundle 1.2 – works fully with unencrypted sparse bundles, can create encrypted sparse bundles but entering passwords for other features doesn’t work with them. This is a change or bug in macOS.
  • T2M2 1.14 – is largely compatible, although figures for the size of each backup aren’t given properly due to differences in result reporting. Otherwise it works correctly even when backing up to APFS.
  • Taccy 1.10 – appears to work fully, including its log browser; 1.10u is a Universal version with specific support for Apple Silicon.
  • Ulbow 1.3 – appears to work fully, although I haven’t yet checked all its features, and haven’t checked to see whether Big Sur adds further fields. The Universal version 1.3u is specifically built for use on Apple Silicon.
  • xattred 1.2 – appears to work fully; 1.2u is a Universal version with specific support for Apple Silicon.

SystHist will need a new version to support Big Sur’s version numbering.

Normally, during beta-testing I don’t provide beta version numbers or firmware data for SilentKnight or LockRattler, as they can change greatly and aren’t useful for other users.

These are all tested on Intel hardware, with Universal versions available where detailed.

If you’re using a Big Sur beta and come across a problem, please report it so that I can fix it and build a new version.
