How to Fix Meltdown and Spectre Security Flaws for Older Macs
Apple has recently released fixes for older Macs running macOS Sierra and OS X El Capitan that also face critical vulnerabilities through the Meltdown and Spectre security flaws. Both Spectre and Meltdown allow attackers to gain unauthorized access to data on computers that have microprocessors running speculative execution. Modern micropro-cessors all use speculative execution to predict next steps and have faster processing speeds. This is common in chips made by Intel and AMD as well as Apple’s A series SoCs. If the predicted path is not required, the instruction set...
