Has your Mac become slow and unresponsive? Has it lost some of the zing it used to have? Are you getting unexpected crashes and error messages? Is your Macbook getting hot and the fan running constantly?

If so, you need to download iBoostUp!

iBoostUp tunes up and optimizes your Mac by purging unneeded files, fixing your hard disk, giving you performance recommendations, protecting your privacy by removing cookies, showing you easily accessible system information, and much more!

iBoostUp's Memory Booster allows you to view detailed system memory information, and optionally free up memory with its "Boost Now" functionality (Boost Now is available to users of Mac OS Lion or above 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 OS Lion 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 Lion 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 Lion 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 Lion 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.

iBoostUp now features 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.

Saved my computer!


It literally deleted 65,000+ cache items that slowed my computer down and took up 100+ gb of space. LIFE SAVER.

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! :)
