iBoostUp frees up space on your Mac by purging unneeded files, gives you performance recommendations, protects your privacy by scanning apps and removing cookies, shows you easily accessible system information, and much more!

Now featuring Spyware Doctor and HID Implant Guard
Using a combination of state-of-the-art heuristic techniques plus cloud based signature scanning, Spyware Doctor* is able to determine whether any app (even those previously unseen) might exhibit malicious behaviour or be a risk to your privacy. Scan any app you download with Spyware Doctor before launching it.

HID Implant Guard alerts and protects you against modified peripherals such as USB drives or Lightning cables designed to tamper with your Mac. It blocks interaction and requests human confirmation whenever a new input device is detected, this prevents keypress injection attacks in the style of "BadUSB", "USB Rubber Ducky" and "O.MG Cable".
(HID Impant Guard is available via in-app purchase)

iBoostUp's Duplicate File Finder helps you regain disk space and reduce clutter by searching for files with identical content, irrespective of location or filename. Duplicate File Finder gives you the opportunity to review and select individual files for removal, but rest assured that in case of inadvertent deletion your files are recoverable from Mac OS's Trash until emptied. (Duplicate Finder is available to Mac Yosemite users or above via in-app purchase).

ARP Cache Poisoning is a hacking technique used to eavesdrop and otherwise manipulate your network traffic. It is of particular concern when connected to untrusted networks such as those found at airports, hotels and cafes.
With iBoostUp's ARP Cache Poisoning Detector you can scan for or be automatically alerted on suspicious network activity. (available to Mac OS Yosemite or above users via in-app purchase)

Reclaim more disk space by using iBoostUp's Application Uninstaller to seek out and remove application related files instead of simply dragging an app to the Trash. (available to Mac OS Yosemite or above users via in-app purchase)

Old and Unused File scanner
Searching for old and unused files on your Mac helps reduce clutter and free up disk space (free for premium users, available to other Mac OS Yosemite or above users via in-app purchase)

Disk Usage Tool
Track down which files and folders consume the most space in your home folder, your Mac's internal or any removable disk. Our Disk Usage Tool is completely free for all users.

App Viewer
App Viewer examines your selected application to display useful and not always easily accessible information. App Viewer is completely free for all users.

Excellent utility

I've used many different Mac utlities over the years, and this one rates at the top. Thses guys are very active on keeping this app current, which I apprecate, given Apple's new acclerated systems updates. The features added in the paid version are worth the cost. Great job, PTY!

Useful app, new update crashes my computer

I downloaded this app about a month ago and have been using it to run a quick clean scan about five times a week. It does a good job of finding extra stuff on my computer to delete and free up space, making my computer run faster. However, I just updated it a day or two ago and when I went to run the scan today, it froze while scanning my cookies. When I say it froze, the app stopped scanning and my computer became extremely sluggish with delayed response and the works. I was able to force quit the app and re-open it. I unchecked the cookies option and ran the scan a second time and it went fine and found a ton of stuff to delete. Then I ran the disk health scan and it froze again. This time I had to re-start my computer. When my computer booted back up, the desktop background was a default Apple background (the milky way one) but everything else seemed normal. When I opened the app again my computer started being sluggish so I immediately force quitted it. I don't know what's going on, but I'm probably going to have to uninstall this app from my computer. When it worked it worked great, but now it's causing me all kinds of problems. I'm worried now that since the background is changed, the app may have deleted/changed some things that it shouldn't have.

What's the big deal?

-This is the third updated version I've owned of iBoostUp - Yes, there was an issue when I tried to open the updated app, AND I want to point out it's VERY simple to fix. Go to their FAQ page (like they say at the top of this page). Click on the issue you are having. Follow the instructions. Done. It's that simple. For the reviewer below saying that it's "far too expensive" an app needs to seriously reconsider what they're saying. YES, it CAN BE expensive (come on though, REALLY EXPENSIVE!? It's the same price as two cups of coffee at Starbucks, and MUCH more useful) IF you buy the added features. You don't "need" to purchase all of the added features (although I must say some of them are quite useful), so even if you download this app it won't lighten your wallet unless you CHOOSE to upgrade. It's SO much easier to use than Onyx, too, and if you really don't want to spend money use onyx for everything that's not free in iBoostup (although it's still much easier in iBoostup and all of the apps only cost a dollar or two). So go ahead. Try it! See for yourself if you like it or not and then YOU decide whether to kepp it or not! :)
