Want to speed up your MacBook? Do these things first

When your MacBook becomes slow, it doesn’t automatically mean it’s time for a factory reset, a third-party optimization tool, or a replacement Mac. Common causes including low storage, high memory usage, and incompatible software. The proper first step is to identify what is actually under pressure and then change what is contributing to the slowdown. These checks won’t turn old hardware into a new machine, but they can reveal performance issues that you may be able to fix.

As a first step, especially if the slowdown is recent, you should restart your MacBook before resorting to more invasive fixes. Choose Apple Menu > Restartthen use the Mac normally for a while and see if the problem reappears. If a particular application is triggering a slowdown, you’ve determined what to investigate by following the steps below.

Let’s start with storage. Apple lists insufficient space on the startup disk as one of the possible reasons why a Mac may be running slowly. Go to System Settings > General > Storage to see what’s taking up space and view the built-in recommendations. If storage space is tight, delete anything you no longer need or consider moving the files elsewhere. A portable SSD can save more space if you’re willing to spend a little.

Then open Activity monitor (the quickest way is to use Spotlight search; tap Command + Space and type “Activity Monitor” while your Mac seems slow. THE Processor The tab shows the CPU capacity used by applications and system processes. If an application repeatedly jumps to the top while the slowdown is occurring, that’s a useful clue as to where to investigate. Try quitting and reopening this app, or reducing its use by closing tabs or similar.

THE Memory The tab answers a different question. Instead of focusing on how much RAM appears to be unused, check the Memory pressure chart. Apple explains that green means memory is being used efficiently, while yellow or red indicate greater pressure. If the graph turns yellow or red, check if an application is consuming a large amount of memory and exit it if you don’t need it. Try to avoid running many memory-intensive applications simultaneously.

Some apps start automatically every time you log in. Open System Settings > General > Logins and Extensions and look below Open at login. If an app doesn’t need to be launched every time you log in to your MacBook, select it and remove it from the list.

The same Settings page includes Background app activity. Apps use this permission to perform tasks when they are not open, including checking for updates or syncing data. Background activity isn’t a problem in itself, but it’s a good place to review software you rarely use or no longer need behind the scenes. Uninstall any Mac apps that no longer interest you.

Don’t disable everything indiscriminately; Apps you rely on for syncing or other background tasks should remain enabled. If Activity Monitor has already directed you to a particular app, its login and background permissions are worth checking.

If your MacBook supports power plans, open System Settings > Battery and check which one is selected. The default Automatic The mode balances power consumption and performance, while Low power Reduces power consumption to extend battery life. If performance is your priority and Low power is activated, returning to Automatic it’s worth a try.

Some MacBook Pro models also support High power mode, but it’s not a universal “make my Mac faster” switch. Apple is positioning it for sustained, demanding workloads such as video-intensive and 3D work, where additional cooling can help the system maintain higher performance. For daily use, Automatic remains the best fault.

Then check System Settings > General > Software Update. Apple recommends using the latest version of macOS compatible with your Mac for security, stability, and compatibility reasons. Updating isn’t a guaranteed performance improvement, but since Apple lists incompatible apps as one of the issues to investigate when a Mac is running slowly, it’s a smart step.

If nothing above helped explain the problem, move on to targeted troubleshooting. Safe mode can help you determine if software loading at startup is involved. macOS uses different stages of Safe Mode for Apple Silicon and Intel Macs, so check out Apple’s Safe Mode instructions to see how it works on yours.

If you have reason to suspect a disk problem, Disk Utility FIRST AID tool (under Applications > Utilities) can check for some formatting and directory errors. Neither Safe Mode nor First Aid constitutes a routine “speed boost”. Use them to investigate a specific problem, rather than for general Mac maintenance.
