Mac Running Slow? 7 Fixes That Actually Work
Before you buy a new Mac, try these 7 fixes. Most of them use built-in macOS tools and cost nothing.
1. Free up disk space (the #1 cause)
macOS slows down when free disk space runs low. OptiClear's Disk Map shows what's eating your storage so you can decide what to remove.
2. Quit memory-hungry apps
Open Activity Monitor → Memory tab and quit anything in red. Chrome, Slack, and Electron apps are common culprits.
3. Trim login items and background agents
System Settings → General → Login Items. Disable everything you don't actively need at startup. OptiClear's System Monitor shows real-time impact.
Frequently Asked Questions
Why is my Mac suddenly so slow?
Usually low disk space, too many login items, or a runaway background process. Run OptiClear's free system scan to identify the cause.
Will cleaning my Mac actually speed it up?
Yes — especially if your disk was almost full. macOS uses free space for swap, caching, and Spotlight indexing.
