v0.8.15

New in 0.8.15

• Checkup is the first tab, with "What's wrong?" at the top. System Sentinel diagnoses the Mac on its own (running hot, processor or memory short, battery draining fast, disk nearly full, an app keeping the Mac awake, a blocked app, a kernel panic) and lists each finding with Fix it. Or pick what feels wrong from ten symptoms: Slow or hot, Battery drains, Disk full, Wi-Fi or internet, Won't sleep, Mic or camera, App crashes or won't open, Bluetooth, iCloud stuck, Restarted by itself. Each opens one panel with what was found and the fixes.
• New checks behind the symptoms: apps refused the microphone or camera, with a one-click reset (needs Full Disk Access); apps macOS calls damaged, with "Allow it to open"; Bluetooth state and connected devices; the last kernel panic in a sentence, naming any non-Apple driver.
• Ignore a finding that is on purpose. A finding about a particular app stays ignored until Show again; a passing state (running hot, low disk) is hidden for a day.
• Crashes are not restarts. A burst of crashes that is over shows as history, not a warning, and command-line programs (compilers, scripts) are not told to reinstall.
• Performance first, security last in the Checkup sections. The Mac's own firewall being off is a note, not a warning: company firewalls and zero trust networks cover it.
• The app reopens on the tab you were last on, across relaunches.
• Route test runs for 1, 5 or 15 minutes or an hour, with a chart of delay and lost pings over time, a minute-by-minute table in the copied report, and a verdict on whether trouble was constant or came and went.
• An old version is obvious: the About button flashes orange and the version line says a newer one is out.
