System Status and Optimization Plan | Generated by AI
Here’s your system status and optimization plan:
System Health
| Metric | Value |
|---|---|
| RAM | 16 GB (Apple Silicon) |
| Active | 7.5 GB / 16 GB — 47% used |
| Swap | 218 MB used — low, healthy |
| CPU | Mostly idle (< 5% outside bursts) |
| User processes | 476 — quite high |
| Free disk | 54 GB |
Top RAM Consumers
| App | RAM | Notes |
|---|---|---|
| Safari WebContent (x5) | ~3.0 GB | Each tab = dedicated WebKit process. TabsKiller limits this. |
| Safari (main) | 315 MB | |
| WeChat + WeChatAppEx | 513 MB | Heavy for a chat app |
| Python (x2) | 292 MB | One at 11% CPU — check what it’s running |
| Zed | 143 MB | |
| WindowServer | 110 MB | macOS compositor |
| GitHub Desktop | 109 MB | |
| Finder | 65 MB | |
| Ghostty | 93 MB | |
| mihomo (proxy) | 36 MB |
Recommendations (sorted by impact)
1. TabsKiller already helping — verify setting
You said it’s keeping 10 tabs. Each closed tab = one ~300-800 MB WebContent process freed. This is your biggest lever.
2. Release Safari WebContent memory
These 5 processes eating 3 GB are your biggest RAM hog. Open the TabsKiller popup and confirm maxTabs is set where you want it. Also consider:
- Safari → Settings → Tabs → set “When closing a tab” → “Close automatically”
- Safari → Develop → Empty Caches (if Develop menu is on)
3. WeChat cleanup
WeChat + WeChatAppEx = 513 MB. If you don’t use mini-programs (WeChatAppEx), you can reduce this:
- WeChat → Settings → General → uncheck “Keep WeChat in background when closing window” if you don’t need it
- Or quit it entirely when not chatting
4. Python processes
Two Python 3.11 processes using 292 MB, one at 11% CPU. Check what’s running:
# Find what started them
ps aux | grep -m2 python
If it’s an idle Jupyter kernel or a stalled script, kill it.
5. mihomo proxy
Running at only 36 MB / 0.9% CPU — fine, no action needed.
6. General cleanup (quick wins)
# Clear system caches (safe)
sudo purge
# Brew cleanup
brew cleanup -s
# Clear user logs
rm -rf ~/Library/Caches/* 2>/dev/null
# Check launch agents (services starting at login)
brew services list
7. Disk — 54 GB free isn’t critical but worth watching
# Find big files
du -sh ~/Library/Caches ~/Downloads ~/.Trash 2>/dev/null
Bottom line: Your biggest wins are (1) TabsKiller keeping tabs ≤ 10 (each tab avoided = ~500 MB saved), and (2) closing WeChat when not in use saves ~500 MB. Together that’s ~1.5 GB freed up, which keeps you well within 16 GB without needing swap.
