MacBook Slow After macOS Update? Here’s How to Fix It
Have you recently installed a macOS update—like the new macOS Tahoe—only to find that your MacBook is now painfully slow? You’re not alone. This is one of the most frequent issues reported by Mac users after updates.
But don’t panic or rush to downgrade. Here’s why your MacBook feels sluggish after an update, and more importantly, how to fix it without losing hours tweaking settings or reinstalling apps.
Why macOS Updates Can Slow Down Your MacBook
1. Reindexing and System Maintenance
Right after an update, macOS performs hidden tasks in the background: Spotlight reindexing, iCloud syncing, app cache rebuilding… all of which put significant load on your CPU and SSD for hours or even days.
2. Background Apps Running Wild
Many background apps (Dropbox, OneDrive, Creative Cloud, Zoom, Slack…) start syncing or updating post-update. Some may run in the background constantly, draining your Mac’s resources silently.
3. New macOS Features = More Overhead
macOS Tahoe and similar updates bring visual enhancements, smart widgets, AI suggestions… all great features, but they consume memory and processing power—especially on Intel Macs or older M1 chips.
How to Speed Up Your MacBook After a macOS Update
✅ Step 1: Pause Non-Essential Apps Using AppHalt
AppHalt is a lightweight utility that lets you pause background applications without quitting them. This instantly reduces CPU load and speeds up your system.
It’s like putting background noise on mute. The difference in responsiveness can be massive—especially if you’re multitasking or working with heavy apps.
✅ Step 2: Check Activity Monitor for CPU Hogs
Go to Applications → Utilities → Activity Monitor. Sort by CPU. Anything using more than 30% constantly should be paused or closed—especially if you’re not actively using it.
✅ Step 3: Clean Up Login Items
Go to System Settings → General → Login Items. Remove anything that doesn’t need to auto-start. This reduces your MacBook’s startup time and prevents resource waste.
✅ Step 4: Use AppHalt’s Smart Sleep Mode
Let AppHalt auto-pause apps that haven’t been touched for over 10 minutes. Great for tools like Discord, Spotify or Chrome tabs that often remain open but unused for hours.
Why AppHalt Is Better Than Generic Cleaners
Unlike cleaning tools that delete caches or “optimize RAM,” AppHalt is focused on live performance control. It helps you reduce app consumption in real time—exactly when your Mac feels slow.
- ✅ Visual indicators (🔴 🟠 🟡 🟢) show each app’s impact
