TinkerTool 5.3 -- Marcel Bresink has released, a maintenance update for the under-the-hood customization system utility that works around an OS X design issue that caused preference settings to be updated only after a major delay. The release also adds new settings that re-enable the Backspace key to navigate backwards in Safari, disable the revised function of the power button to switch to sleep mode (10.9.2 or later only), control the speed of Mission Control animations, and use Notification Center to display information about crashes. Bresink also notes that TinkerTool’s internal architecture has been updated to prepare for the latest developments in OS X, but does not specifically address support for OS X 10.10 Yosemite.

While Marked 2 replaces the original Marked app in the Mac App Store, Marked 2 is not a free update — though it is on sale for $9.99 for a limited time (both from the Mac App Store and the Marked Web site). The update now supports GitHub Flavored Markdown for the app’s Discount processor option, preserves bookmarks across refreshes and style changes, adds highlight navigation and highlighted word counts, fixes a problem with reading the most recent file in a folder, improves handling of unreadable and renamed files, and fixes an issue with initial file monitoring when opening in an external editor. Because Marked 2 is sandboxed, previously opened documents may require new permissions. Marked 2 doesn’t currently support OS X Yosemite, but Terpstra promises it will be added soon.
