1. Why Is Your Mac Running Slow After Update? 🐢
If you notice your Mac running slow after update, you’re not alone. This often happens because macOS reindexes system files and Spotlight after major updates, which temporarily consumes CPU and memory. Give your Mac a few hours to settle, especially if it was a big upgrade.
2. Check Activity Monitor for Background Tasks 🛠️
After an update, background processes like Photos syncing, iCloud uploads, or system reindexing can slow your Mac down. Open Activity Monitor and look for apps using high CPU or memory. Terminate any that aren’t essential.
3. Reset SMC and NVRAM to Improve Speed 🧠
Sometimes your Mac running slow after update can be fixed by resetting the SMC (System Management Controller) and NVRAM. These resets help fix performance glitches. Learn how to reset these on Apple’s official guide: Reset SMC and NVRAM.
4. Free Up Storage Space After the Update 📦
macOS updates often require extra temporary space. If your disk is near full, performance will suffer. Go to → About This Mac → Storage and delete unnecessary files, apps, or use tools like AppHalt for deeper cleanup.
5. Disable Startup Items Slowing Your Mac 🔧
Some apps auto-launch after update and slow down your system. Go to System Settings → General → Login Items, and disable anything non-essential.
Extra Tip 💡
If you’ve just upgraded to a new macOS version, some older apps may no longer be optimized. Visit the developer’s site or use tools like RoaringApps to check compatibility.
