A slow MacBook can be incredibly frustrating when you rely on it for work or study. The good news is that many MacBook performance issues can be resolved without replacing the machine. Protech Repair in Cheam helps MacBook owners across South London restore their devices to full performance.
Quick Answer: Why Is My MacBook Running Slow?
MacBooks slow down due to insufficient storage space, too many background processes, an old mechanical hard drive, insufficient RAM, an outdated macOS version, or accumulated thermal paste degradation causing the processor to throttle. Most of these issues are fixable without buying a new MacBook.
How To Speed Up a Slow MacBook
1. Free Up Storage Space
macOS requires free space to operate efficiently. Click the Apple menu, go to About This Mac, Storage, and Manage to see what is taking up space. Delete unused applications, empty the trash, and move large files to an external drive or iCloud.
2. Check Activity Monitor
Open Activity Monitor (Finder > Applications > Utilities) to see which processes are consuming the most CPU and memory. Quit any apps that are using excessive resources when you are not actively using them.
3. Update macOS
Apple regularly releases macOS updates that include performance improvements. Go to System Settings > General > Software Update to check for and install available updates.
4. Upgrade to an SSD (Older MacBook Models)
MacBook models from 2012 to 2015 with spinning hard drives benefit enormously from an SSD upgrade. Protech Repair in Cheam installs SSD upgrades in compatible older MacBooks, transforming them into fast, responsive machines at a fraction of the cost of a new Mac.
5. Upgrade RAM (Where Possible)
Older MacBook models with upgradeable RAM can benefit from a memory increase. Modern Apple Silicon MacBooks have soldered RAM that cannot be upgraded, but older Intel models often can be. Our Cheam team can advise on whether your MacBook supports a RAM upgrade.
6. Replace Thermal Paste
In older MacBooks, the thermal paste between the processor and heat sink degrades over time, causing the processor to run hot and throttle its performance. A thermal paste replacement as part of a full service can restore full processor performance.
