修正 Mac 外接螢幕的 Underscan 問題

公司的 MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) 透過 HDMI 接 Dell P2419H 一直都有 Underscan 的問題:

本來想透過 Underscan slide 修改 (像是下面這張圖),但發現系統內沒有 Underscan slide。

找了不少文章後後來是在「Fixing Issues with Overscan/Underscan(Black Borders) on macOS」這篇的 comment 看到解法:

Ran into this same underscan problem with black borders showing up on my new Dell 24-inch Ultrasharp U2415 connected to a 2013 Macbook Air running High Sierra, and after hours of looking into the problem the fix turned out to be super simple:

Just restart in Safe Mode.

That’s it. Restart your Mac in Safe Mode (restart, hold down the Shift key after the Apple BONG sounds, then restart normally once again for good measure. I don’t know what this clears or resets but it worked for me. No more letterboxing or black borders with the native 1920×1200 resolution selected.

So maybe something to try first for anyone coming across this post.

照著重開進 Safe mode 後再開回一般模式就正常了 (what???),先記錄起來,讓我之後遇到時可以搜尋到自己的文章...

Spotify 向歐盟投訴 Apple Music 的不公平競爭

Spotify 向歐盟提出不公平競爭的投訴,並且發出新聞稿:「Consumers and Innovators Win on a Level Playing Field」。

重點在於 Spotify 服務透過蘋果的平台會有 30% 的抽成,但 Apple Music 因為自家服務而不需要:

To illustrate what I mean, let me share a few examples. Apple requires that Spotify and other digital services pay a 30% tax on purchases made through Apple’s payment system, including upgrading from our Free to our Premium service. If we pay this tax, it would force us to artificially inflate the price of our Premium membership well above the price of Apple Music. And to keep our price competitive for our customers, that isn’t something we can do.

不過裡面好像沒提到超過一年後的費用會降到 15% (參考「Auto-renewable Subscriptions」),應該會是蘋果向歐盟回應的重點?

所以蘋果開始放鬆 iPhone 的第三方電池保固問題了?

MacRumors 上看到的,先前只要透過第三方更換電池,蘋果就會拒絕後續所有保固,現在內部文件改成不保固電池的部分,其他的元件還是會提供保固:「Apple Says iPhones With Third-Party Batteries Now Eligible for Repairs」。

iPhones with aftermarket batteries installed by third-party repair shops are now eligible for service at Genius Bars and Apple Authorized Service Providers, according to an internal Apple document obtained by MacRumors from three reliable sources.

不確定是不是全球性的,但至少法國已經是了?

突然想到『FTC 警告 Nintendo 與 Sony「拆封喪失保固」違反聯邦法』這篇,雖然兩者討論的主題不太一樣...

WireGuard 上 macOS 了...

在「WireGuard for macOS」這邊看到 WireGuard 進到 Apple 家的 Mac App Store 了。

除了是透過 app store 下載外,另外的重點在於整合了 NetworkExtension API

This is built from the same code base as our existing iOS app and makes use of Apple's Network Extension API to provide native integration into the operating system's networking stack.

這樣可以確保相容性,而且可以用內建的 VPN 機制管理。另外也給了一些 screenshot 可以看,可以看出來就是走 Mac 上的管理方式:

Apple 將移除掉 Safari 的 DNT 功能

在「Apple Removes Useless 'Do Not Track' Feature From Latest Beta Versions of Safari」這邊看到的,看起來包括 iOSmacOS 都會移除:

因為沒什麼單位願意遵守,沒必要多送幾個 bytes 還順便讓廣告商可以判斷...

用關鍵字搜尋 Apple 的 App Store 對不同地區的上架情況

The Intercept 提到了 Apple Censorship 這個站,可以丟關鍵字進去看 app 在不同地區的上架情況:「New Site Exposes How Apple Censors Apps in China」。

預設有美國 (United States) 與中國大陸 (China (mainland)) 當作比較,也可以自己增加地區。除了拿來看 censorship 外 (像是搜尋 vpn 或是 tor),也可以看其他的 app 上架的情況...

整個站其實頗簡單的,是個簡單的 PHP 站台,可以參考 GitHub 上的 greatfire/applecensorship 專案。

DuckDuckGo 開始改用 Apple Maps

DuckDuckGo 宣佈採用 Apple Maps 當作搜尋頁提供地圖資訊的資料來源:「DuckDuckGo Taps Apple Maps to Power Private Search Results」。

DuckDuckGo 官方的說法看起來應該是 proxy 之類的方式實做,從瀏覽器的連線上看起來是透過 proxy*.duckduckgo.com 傳輸:

We do not send any personally identifiable information such as IP address to Apple or other third parties.

畢竟地圖是砸錢做出來的東西,Apple Maps 的資料應該沒有 Google Maps 豐富,但就搜尋頁上翻起來應該算是夠用?(尤其對歐美區域)

另外「DuckDuckGo switches to Apple Maps for search results」這邊則是給了反對意見,提到 Apple Maps 的品質一直都不怎樣...

Yubico 宣佈推出 Lightning 的 U2F 界面...

YubicoCES 2019 上宣佈推出兩用版的 YubiKey,同時支援 USB-CLightning 接頭:「Yubico Launches the Security Key NFC and a Private Preview of the YubiKey for Lightning at CES 2019」。

從照片可以看出來是直接做成兩側各一個頭:

目前是 Private Preview,開發者需要跟 Yubico 申請:

If you are a developer or service that would like to support strong hardware authentication on iOS, we invite you to work with us by applying to participate in the YubiKey for Lightning Program. Selected participants will have access to the private preview of YubiKey for Lightning and also the Yubico Mobile iOS SDK for Lightning.

不過看起來是硬體限制沒辦法朝 NFC 支援?另外如果蘋果下一代 iPhone 換掉變成 USB-C 就搞笑了...

Mozilla 跟 Google 都宣佈了 TLS 1.0 與 TLS 1.1 的退役計畫

UpdateApple 也宣佈了,時間點跟大家都差不多:「Deprecation of Legacy TLS 1.0 and 1.1 Versions」。

Mozilla 宣佈了「Removing Old Versions of TLS」,而 Google 也宣佈了「Modernizing Transport Security」,兩篇都是講自家瀏覽器 TLS 1.0 與 TLS 1.1 的退役時程。

Mozilla 這邊的計畫是 2020 年三月移除:

In March of 2020, Firefox will disable support for TLS 1.0 and TLS 1.1.

Google 這邊的計畫則是 Chrome 81 移除,換算成時間會從 2020 年一月開始影響到 canary channel,到 release channel 應該跟 Firefox 差不多時間:

In line with these industry standards, Google Chrome will deprecate TLS 1.0 and TLS 1.1 in Chrome 72. Sites using these versions will begin to see deprecation warnings in the DevTools console in that release. TLS 1.0 and 1.1 will be disabled altogether in Chrome 81. This will affect users on early release channels starting January 2020.

差不多試從現在開始的一年半。

雖然這是講瀏覽器端的支援,但如果伺服器想要只支援 TLS 1.2+ 的話,就得考慮一下舊 client 支援的情況了。

桌機影響會比較小 (升級比較方便,替代方案也比較多),而行動平台看起來需要 Android 4.4+、iOS 7+,就要看各網站或是服務的族群了...
