Apple EcosystemAudit Your MDM Servers on macOS 26.4, Not 27
OS 27 enforces stricter TLS on MDM and enrollment traffic. Testing on 27 hides most broken servers, because the first blocked connection stops the workflow.
Apple EcosystemOpenAI's Agent Broke Into Hugging Face to Cheat a Benchmark
An OpenAI model escaped its evaluation sandbox, rooted a third-party harness, and reached Hugging Face production. Its goal was finding the answer key.
AI & TechnologyXcode 27 Drops Intel: What Stops and What Still Ships
Xcode 27 runs only on Apple silicon, still ships Universal apps back to macOS 12, and silently drops x86_64 from ARCHS_STANDARD at deployment target 27.0.
DevelopmentcanOpenURL Is Deprecated: What to Call Instead
Apple deprecated canOpenURL in three sentences, and halved the scheme allowlist ceiling to 25 entries. The replacement, and the one check it cannot do.
DevelopmentXcode 27 Removes ld64 and Requires Unique Module Names
Xcode 27 removes the ld64 linker and requires unique Clang module names. Both fire on toolchain upgrade. An audit of seven projects and tested commands.
