Crash Reporter

Crash Reporter has three modes of operations:

  • Basic — The default mode. Only application crashes are reported, and the dialog does not contain any debugging information.
  • Developer — In addition to application crashes, crashes are also displayed for background and system processes.
  • Server — The default for macOS Server systems. No crash reports are shown to the user (though they are still logged).
  • None — Disables the dialog prompt. Crash reports are neither displayed nor logged.

SAFARI ENEBLE TLS 1.3 (TLS 1.3 – BETTER, FASTER, STRONGER)

Alapértelmezetten támogatott de nincs engedélyezve.
Pedig minden előnye mellett min. 3x gyorsabban töltődnek be az oldalak.

Leggyakoribb méréseim szerint:
Normál TLS1.1 vagy TLS 1.2 oldalletöltése 1.5 – 1.8s
TLS 1.3 használatával 330 ms
Lol!

Bekapcsolása terminálban:
