This morning while perusing the settings of a bunch of apps on my iPhone, I discovered a new setting for Photos that was enabled by default: Enhanced Visual Search. (I manually disabled it before taking the screenshot below.)
When you launch an app, macOS connects to Apple's OCSP service to check whether the app's Developer ID code signing certificate has been revoked by Apple. In November 2020, Apple's OCSP service experienced a mass outage , preventing Mac users worldwide from launching apps. In response and remedy to this outage, Apple…
Firefox version 115.0 was released on July 4, but I'm not celebrating. I'm concerned about a new "feature" in the release notes .
I'm organizing a boycott of Apple's Feedback Assistant , starting immediately, and I encourage all Apple developers to join me. Here's how I propose that each of us can effectively participate in the boycott and let Apple know that we're boycotting Feedback Assistant:
This blog post doesn't have the answers. I'm trying to learn about passkeys, but I don't claim to be an expert. I do have a lot of questions, especially for Apple, because I'm an Apple user and developer. According to Betteridge's law of headlines , "Any headline that ends in a question mark can be answered by the…
This is a follow-up to my blog post Updating from macOS Ventura to Sonoma silently enables iCloud Keychain . In the addendum to that blog post, I discussed a workaround, which was to delete my WiFi password right before rebooting into the updater. In a trial run on my M1 Mac mini, the workaround was successful.
This is a follow-up to my blog post macOS Sonoma silently enabled iCloud Keychain despite my precautions from five months ago. The TL;DR of that blog post is that when you have iCloud enabled but not iCloud Keychain, updating from Ventura to Sonoma causes iCloud Keychain to be silently enabled. (I don't know yet…
Some people who had previously disabled Apple Intelligence in macOS 15.3 and iOS 18.3 saw it re-enabled after updating to macOS 15.3.1 and iOS 18.3.1 today. In fact I personally have two different Apple silicon Macs running macOS Sequoia, and after I updated both Macs to 15.3.1, Apple Intelligence was re-enabled on my…
Yesterday I discovered a deluge of recent fake customer reviews for a number of top paid apps in the United States Mac App Store. (Each country has its own version of the App Store with separate reviews.) I've now checked the reviews for all of the current top 40 paid apps in the Mac App Store, and 8 of those apps…
I've always attributed slow Xcode launches to Xcode simply sucking, but I've noticed that the FileMerge app frequently launches slowly too. When this happens, the app can take a dozen bounces in the Dock before finally opening. FileMerge resides in the folder Xcode.app/Contents/Applications/ within the Xcode bundle…
I bought a new M1 MacBook Pro in April 2022. A little over two years later, I'm seeing a service recommended message, and the maximum capacity of the battery is now down to 78%. Admittedly, my MacBook Pro experiences heavy usage: basically all day, every day. The batteries in my previous 2014 Intel MacBook Pro, which…
