Mac Hardware and Configuration

GPU and CPU are integrated in to the M1 chip.

Sleep vs. Shutdown

For M1/M2 Macs, closing the lid to sleep 1-2 times weekly is sufficient; frequent shutdowns are unnecessary due to improved architecture. On Windows, disable "Fast Startup" and set timed hibernation to prevent memory aging.

Disk Space Management

Use Mac-specific cleaners like https://lemon.qq.com/ when disk space is full.

Installation

Package Types

• Apple Silicon Mac (e.g., M1, M2): Use arm64.dmg.
• Intel Mac: Use dmg.

Developer Verification Issues

Input Methods

Touch ID and Lock Screen

App Management

Access apps via Finder > Applications. For downloads with out internet access, search directly on GitHub.

Host Switching and Hosts File

Use tools like SwitchHosts to switch hosts. Modify the hosts file to redirect specific websites.

Principle: Local Priority

When accessing a domain (e.g., www.bilibili.com), resolution order is:

1. Browser/system cache.
2. Local hosts file.
3. Remote DNS servers.

Pointing a domain to 127.0.0.1 (loopback address) blocks access by redirecting requests to your own computer, preventing external DNS queries.

Editing Hosts File

• Windows: Run Notepad as administrator, open C:\Windows\System32\drivers\etc\hosts, add entries (e.g., 1x.x.x.x xxxxx.corp.com), and save.
• macOS/Linux: Use sudo vi /etc/hosts in terminal, press i to edit, add entries, press Esc, then :wq to save.
• Verification: Run ping xxx.corp.com in terminal; if it returns 1x.xx.xx.xx, it's successful.

Network Configuration

Viewing IP Address

• Terminal: Use ipconfig getifaddr en0 for Wi-Fi or ipconfig getifaddr en1 for Ethernet.
• System Settings: Go to Wi-Fi > Details > TCP/IP > IP Address.

Static IP Setup

1. Disable VPNs, proxies, or security software.
2. Enter desired static IP in network settings.
3. Set DNS (e.g., Google DNS: 8.8.8.8, 8.8.4.4).
4. If connection drops, clear ARP cache with sudo arp -a -d and restart network with sudo ifconfig en0 down && sudo ifconfig en0 up.

Ports and Services

Ports identify programs/services (e.g., HTTP uses port 80, development servers use 8080). Use lsof -i :port_number to check port status.
