MacBooster 8 Features

During our testing at DroidCrunch, we put every module of MacBooster 8 through its paces on a MacBook Air that had become noticeably sluggish. Here’s a personalized breakdown of how each feature performed.

System Junk Cleaner

Every time a Mac is used, it creates temporary files. Applications generate caches to load faster, the system keeps log files to track operations, and browsers store data from websites. While these files are initially useful, they often become outdated or are left behind, needlessly consuming storage.

The System Junk module is engineered to intelligently scan specific locations in macOS where this digital clutter accumulates. It identifies and categorizes everything from old application language packs to broken user preferences.

Clearing this junk recovers a significant amount of disk space and helps the system run more efficiently, as it no longer has to manage obsolete files.

Virus & Malware Scan

The notion that Macs are immune to viruses is a myth. While macOS has strong built-in security, it’s increasingly targeted by adware, spyware, and other malicious software that can compromise privacy and slow down the machine.

MacBooster’s Virus & Malware Scan provides a critical layer of protection by performing a deep scan of the system to find and neutralize these threats.

This feature is essential for ensuring personal data remains secure and the Mac isn’t being used for malicious activities in the background.

Turbo Boost

The Turbo Boost feature is a performance optimizer that targets two key areas of a Mac’s health. First, it addresses disk permissions.

As software is installed and uninstalled, the permissions that dictate which apps can access certain files can become scrambled, leading to errors or slowdowns. Turbo Boost resets these to their correct default settings. Second, it optimizes storage by cleaning caches related to media and apps.

This can be particularly effective on machines with standard hard drives, making heavy applications feel snappier and the overall system more responsive.

Memory Clean

RAM (Random Access Memory) is the Mac’s short-term memory, where it keeps all the data for currently running applications. When many apps or browser tabs are open, RAM can fill up.

When this happens, the Mac starts using its much slower main storage as “virtual memory,” causing slowdowns. The Memory Clean tool provides a one-click solution to this problem.

It identifies inactive processes and data that are unnecessarily hogging RAM and purges them, instantly freeing up memory for active tasks. Using this before a demanding task can lead to a significant reduction in lag.

Uninstaller

Dragging an application to the Trash only deletes the main program file, leaving behind a trail of associated files, including preferences, support folders, and caches. These can waste gigabytes of space and potentially cause conflicts.

MacBooster’s Uninstaller is a powerful tool that ensures a complete removal. When used to delete an app, it first locates the main program and then diligently hunts down all its scattered satellite files.

It presents a comprehensive list, allowing a user to remove every last trace with a single click.

Large & Old Files Finder

It’s easy to lose track of what’s taking up space on a Mac. The Large & Old Files finder is a tool that scans the entire drive for files that are both sizable and haven’t been accessed in a long time.

It can unearth old video project exports, downloaded disk images (.dmg files), and ZIP archives. By presenting these in a clear, sorted list, it allows users to make informed decisions and quickly reclaim a massive amount of storage without having to manually search through folders.

Duplicate Finder

Duplicate files are silent storage hogs. They can be duplicate photos from an import, multiple downloads of the same document, or copies of music files.

The Duplicate Finder uses a sophisticated algorithm that compares the actual content of files, not just their names or dates, making it incredibly accurate.

When pointed at a Photos library, for example, it can correctly identify numerous identical images, presenting them side-by-side for easy review and deletion.

Startup Optimizer

A slow boot time is often caused by too many applications trying to launch at once when the Mac turns on. The Startup Optimizer provides a simple, centralized control panel to manage these “login items.”

It displays a list of all the apps and processes set to run on startup. This allows users to easily disable non-essential items with a simple toggle, giving them direct control over the Mac’s boot process and improving how quickly it gets to a usable desktop.

MacBooster 8 Pricing

MacBooster 8 uses a simple three‑tier structure—Standard, Premium, and Lite—so it’s easy to match features and device limits to the setup.

All tiers include the full cleaning and optimization toolkit, while Premium adds priority support and Lite scales to more Macs at a lower per‑device cost. Promotions in the screenshot show sizable savings, so final totals may vary during sales.

Plan	Pricing	Devices	Typical price notes	Best for
Standard	$2.49 / month	1 Mac	Often shown around the lower annual tier with periodic discounts	Solo users on a single Mac who want all core tools
Premium	$4.16 / month	3 Macs (frequently shown as 2 + 1 free)	Mid‑tier annual pricing, commonly promoted with higher percentage discounts	Households or creators with multiple Macs needing faster support
Lite	$89.95 / month	5 Macs (per the screenshot)	Higher headline price but economical per device during promos	Small teams needing more seats at a lower per‑device cost

Notes

• The screenshot indicates time‑limited discounts (e.g., “Save 62%”) and urgency badges; actual totals can change with active promotions.
• Feature coverage across tiers is the same; the main differences are device count and whether priority support is included.
• If budget is tight and only one Mac is in use, Standard is the straightforward pick; for 2–3 Macs and faster help, Premium is the value sweet spot; for 4–5 Macs, Lite reduces the per‑device cost.

Choosing an alternative to MacBooster 8 depends on whether an all‑in‑one suite or a focused cleaner is preferred. CleanMyMac X and MacKeeper bundle cleaning, optimization, and security in one place, while DaisyDisk and OnyX shine for targeted, manual control. BuhoCleaner and CCleaner deliver fast, lightweight tidying for everyday use.

Step 3: Best Practices for Effective Use

• Review Before Deleting: Always review the files found by “Large & Old Files,” “Duplicate Finder,” and “Uninstaller” before deleting them to ensure you don’t remove anything important.
• Set a Schedule: In MacBooster’s preferences, you can schedule regular scans to run automatically in the background, keeping your Mac maintained without manual intervention.
• Frequency of Use: A full system scan once a week is generally sufficient for most users. Use tools like “Memory Clean” on an as-needed basis when you notice performance drops.

MacBooster Use Cases

MacBooster 8 is a versatile tool that addresses several common issues faced by Mac users. Here are some specific situations where it is particularly effective:

1. Reclaiming Critically Low Disk Space

This is a frequent use case, especially for users with baseline MacBook models that have limited SSD storage. For anyone who constantly sees the “Your startup disk is almost full” warning, MacBooster provides a direct solution.

2. Restoring Speed to a Slowing Mac

Over time, a Mac can feel less responsive, applications may launch slower, and multitasking can become frustrating. This indicates that the system requires optimization.

3. Enhancing Security and Removing Malware

For users who frequently download files or applications from various sources, there is a risk of inadvertently installing adware, spyware, or other malware.

4. Simplified, Automated Mac Maintenance

Many users are not technical and prefer an automated solution to keep their Mac running well without manual intervention.

5. Preparing a Mac for a New Owner

Before selling or giving away a Mac, it is essential to remove personal applications and data traces. MacBooster helps streamline this process.

6. Managing Multiple Macs in a Household

For families or small businesses with several Macs, buying individual software licenses for each machine can be inefficient. MacBooster’s licensing model is designed for this scenario.
