Mac Running Slow? 8 Fixes That Actually Work in 2026
Your Mac used to be fast. Now it crawls. Here are 8 proven fixes ordered from easiest to most impactful.
Fix 1: Restart Your Mac
Modern Mac users rarely restart their computers. Many leave them in sleep mode for weeks or months. Over time, memory leaks from apps accumulate and slow everything down. Restarting clears the RAM and resets all processes. Click the Apple menu and select Restart. If you have not restarted in more than a week, this alone may noticeably improve speed.
Fix 2: Manage Login Items
Go to System Settings, General, Login Items. Every app listed here launches at startup and runs in the background consuming memory and CPU. Remove anything you do not need running at all times. Common offenders include Spotify, Adobe Creative Cloud, Microsoft Teams, Dropbox, and various utility apps. You can still launch these manually when you need them.
Fix 3: Free Up Storage
Click the Apple menu, About This Mac, Storage (or System Settings, General, Storage on newer macOS). If your drive has less than 10 percent free space, macOS slows down significantly because it needs free space for virtual memory, caches, and temporary files. Delete or move large files, empty the Trash, and use the Reduce Clutter recommendations that macOS provides. Offload photos and videos to iCloud or an external drive.
Fix 4: Close Memory-Hungry Apps
Open Activity Monitor from Applications, Utilities. Click the Memory tab and sort by Memory column. Chrome is typically the biggest memory consumer, especially with many tabs open. Each Chrome tab runs as a separate process. Consider using Safari which uses significantly less memory on Mac. Also check for apps using excessive CPU — sort by CPU column and force quit anything using high CPU that you are not actively using.
Fix 5: Reduce Visual Effects
Go to System Settings, Accessibility, Display. Turn on Reduce Motion and Reduce Transparency. These visual effects consume GPU resources and can slow down older Macs noticeably. The visual difference is subtle but the performance improvement can be significant, especially on Macs older than 3 to 4 years.
