保護 macOS 的方法

在「drduh/macOS-Security-and-Privacy-Guide」這邊列出了許多保護方式,如果考慮到 APT 的話應該是個不錯的指南... 不過考慮到相當硬,服用前請小心,有些步驟甚至需要拆機: 雖然整篇文章還頗硬的,但裡面講軟體的部份還是很不錯的指南,可以保護自己...

Amazon WorkSpaces 可以透過瀏覽器直接存取了

應該是 AWS re:Invent 前夕,有不少東西都先發表出來了... 這次是公開 Amazon WorkSpaces 可以透過瀏覽器登入操作了:「New – Web Access for Amazon WorkSpaces」。 話說回來,後來才知道這種服務是配著像是「Amazon WorkSpaces with HP Zero Client Computing」這樣的硬體在用... 不過對於靠電腦吃飯的還是用 Laptop 或是 Desktop 會比較順暢就是了 :o

配合 Touch ID 的 sudo

Linux 下多點觸控的設定

看到「Multitouch gestures with libinput dirver on X11, Linux」這個專案,可以在 Linux/X11 下偵測到多點觸控,然後設定對應的按鍵,從他的設定檔就可以看到這套軟體的功能了: swipe: 3: left: shortcut: 'alt+Right' right: shortcut: 'alt+Left' up: shortcut: 'ctrl+t' down: shortcut: 'ctrl+w' 4: left: shortcut: 'super+Right' right: shortcut: 'super+Left' up: shortcut: 'super+a' down: shortcut: 'super+s' pinch: in: shortcut: … Continue reading

MBPR 觸控板壓力回饋失效的問題

Short Version:遇到這個問題,只要把作業系統從 10.10 更新到 10.12 就好了:「Mac Users Reporting Widespread System Freezes With OS X El Capitan 10.11.4 Update」。 之前 MBPR 在過保後掛過一次送修 (常常無法開機,開起來後鍵盤與觸控板都沒有反應),當時把鍵盤與觸控板都換掉... 結果前幾天發生觸控板的壓力回饋失效的問題 (還是可以移動滑鼠游標與輕觸),但這幾天要去日本,想帶著處理事情,就先上 24h 買個 Magic Mouse 2 應急 (用 lightning 充電的那個版本,被嘲笑很醜的那個 XD)。 買回來後發現 Magic Mouse 2 的多點觸控與電量資訊沒有顯示在系統裡,翻了資料才發現要 10.11 … Continue reading

所以 Apple 也開始玩自動下載新版作業系統這招了...

在「Apple starts downloading MacOS Sierra automatically to your MacBook — Here's How to Stop It」這邊看到 Apple 會自動下載新版作業系統,大約吃 5GB 的流量愈空間: If you have automatic downloads enabled on your Mac, a large file of around 5GB will mysteriously be downloaded to your … Continue reading

iOS 阻擋 WoSign 憑證

在 mozilla.dev.security.policy 上看到有人行動了:「Apple's response to the WoSign incidents」。這使得 Apple 成為 WoSign 事件中第一個行動的單位。 Apple 這次先把 WoSign 放入 iOS 憑證清單的黑名單公告在這邊:「Blocking Trust for WoSign CA Free SSL Certificate G2」。 WoSign 在 iOS 產品線中是靠 StartCom 與 Comodo 的交叉簽章,所以如果 Apple 只想擋 WoSign 憑證的話,必須以阻擋 Intermediate CA … Continue reading

FreeBSD 11.0 重新發行...

本來已經發行的 FreeBSD 11.0,因為最近的安全性問題 (應該是講 OpenSSL?),決定不以 security update 的方式更新,而是直接發新版了:「[REVISED] [HEADS-UP] 11.0-RELEASE status update」。 Although the FreeBSD 11.0-RELEASE has not yet been officially announced, many have found images on the Project FTP mirrors. However, please be aware the final 11.0-RELEASE will be … Continue reading
