MacBooster 8.3.0 on Mac

Startup Optimizer is the one you open first. It shows every login item and background service, so you can cut the ones slowing your boot. That alone makes a difference on older Macs.

Junk file cleanup

MacBooster targets twenty types of junk — system caches, app leftovers, logs, broken downloads. The scan takes seconds, and you preview what will go before you confirm. Keeps your drive from filling up with stuff you forgot existed.

Malware removal

The malware scanner checks for adware, spyware and viruses that slipped past macOS’s built-in defences. It quarantines what it finds and gives you a report. For most people, that’s a once-a-month run.

Disk and memory tools

You can repair disk permissions, clear unused RAM, and find duplicate files or photos. The duplicate finder is handy if you sync folders from old backups. Seven tools in one place, all accessible from the sidebar.

Catches more cache types from browsers and messaging apps

MacBooster 8.3.0 keeps the same seven-tool layout, but the cleanup engine now catches more cache types from common browsers and messaging apps. The malware definitions are updated too — IObit pushes them server-side, so the scanner recognises newer adware variants without needing a full app update. The duplicate finder in this version handles larger photo libraries without hanging the interface. If you run it on an Apple Silicon Mac, the optimisation routines use the native architecture, which means less translation overhead in the background.

2019 Intel MacBook Pro boot time drops after disk optimisation

Say you have a 2019 Intel MacBook Pro that you use for freelance writing. You clear those. Then you open the disk optimisation tool, which defragments metadata and reorders file access patterns. The boot time drops noticeably. You also check startup items and disable a printer utility that launches every login. The Mac feels more responsive, and you haven’t spent money on a new machine.

Start with a full scan, then preview junk before approving

Start with a full scan. Let MacBooster run its junk, malware and performance checks in sequence. That gives you a baseline of what your Mac looks like. Don’t approve every junk suggestion blindly — preview the list first. Some caches belong to apps you use daily, and clearing them just forces a rebuild.

Run the duplicate finder only after you’ve freed up space from junk. It takes longer and works better when the drive isn’t cluttered with temporary files. The virus definitions update automatically, so you don’t need to check for new versions.

Finally, open Startup Optimizer once and decide which items you really need at boot. If you skip this step, the other tools still help, but the biggest day-to-day gain comes from a faster startup. Leave the memory cleaner for moments when the Mac feels sluggish — it’s not something you need to run every session.
