A friend who is switching from Yahoo mail to Apple's Mail app asked me if there was anyway to password-protect Mail so that roommates, who have access to his Mac, can't easily peruse his mail. After poking around the web I stumbled upon MacAppBlocker, and installed it on my MacBook Pro to test it. I've only used it a short time, but it does exactly what the developer says: keeps anyone who doesn't know your password from opening protected apps. The app is very easy to configure and use, and you're alerted if someone does try to access one of your protected apps: MacAppBlocker's menu icon turns red. Oops, busted. MacAppBlocker is not a high-security app; a computer-savvy intruder can access documents other ways than thru the app which created them. But in a casual setting (family computer use, roommates, etc) it might be a fine solution. And no, I have nothing to do with the developer; I'm just fairly enthusiastic about the app, which seems to be well done.

Great app to protect my browser & mail app. I love that I can set it to hide the apps after some time of not being used, and then ask again a password to open them. Off course there are ways to bypass the app as another used commented, but at least for me, i´m not surrounded by people with that skills, i just want to keep away from my stuff the people in the office or someone stealing my computer. Also Ken has been very responsive after the mails I sent him asking some fixes.

This is so easy to circumvent:
Two ways:

- Because you cannot remove the .app file yourself, you need a decent uninstaller like iTrash or AppDelete. They will force it to delete and it works every time, even with locked apps like this. Succesfully removed it on macOS10.12

- Write a small AppleScript (if the script editor is locked too, use another system) and save it as a AppleScript:

tell application "System Events"
try
do shell script "killall MacAppBlocker"
delete login item "MacAppBlocker"
end try
end tell

Run the scripts and gone is the protection.

Beside the poor protection, even for an average user, the app itself is badly written. It leaks a LOT of memory.
It does sometimes locks up the CPU with high peak usages, which seems random.
On top I found two apps that it did not want to lock.
It is too bulky and counterproductive GUI.

Even for free this is not worth using.

It’s true that Mac App Blocker can be disabled with this AppleScript. However, it seems that this method is certainly beyond the abilities of the “average” user.
This AppleScript uses the OS functionality at the lowest level to disable an app. It would be very inappropriate for any app developer to prevent operation of the OS at this level.

The criticism that Mac App Blocker is a memory hog with memory leaks is simply now true.
In the 5 years that Mac App Blocker has been available, it has NEVER overloaded a CPU to the point of making the computer unresponsive. We have NEVER heard from anyone that the app had caused a system lockup or even hinted at an issue with CPU usage.

The app is throughly tested on multiple computers with multiple OS versions before release. If this user is experiencing this issue, I would suggest looking elsewhere for potential culprits - because its NOT from Mac App Blocker.

Though, maybe I’m being too critical of this users review. After all, the app was just released yesterday and this user has already spent an exhaustive amount of time evaluating it - in the past 12 hours. (In addition to reviewing 8 other apps here on MacUpdate at the same time).

Why is it that whenever we release a new version, we receive a number of negative reviews - though competitive apps do not receive the same critiques. Even though the issues and faults of Mac App Blocker could easily apply to the other apps, they never receive these 1 star reviews.

As always - everybody is entitled to his/her own opinion. Some users may find Mac App Blocker useful and others may not. This is why we offer a 15 day trial period.

You should chill. Really, take my comments as a gift to improve your tool instead of saying my comments aren’t true. That is plain rude and doesn’t make you look any better. Respect to your customers is in place here.

The memory leaking is very true. Watching the Activity Monitor while adding a new app to protect results in about +5MB and removing it back again +5MB. Launching a protected app also leaks memory. I can imagine if it run for days without hard resetting a system, it can become a serious problem. I noticed this in the Activity Monitor because of the CPU peaking problems that I noticed before.

About CPU hungry. This is true too. Sometimes launching a protected app gives the rainbow pointer and CPU is peaking for long time until the unlock window is shown. This is random but it does happen here.

I tried your app in the past and had the same problems. I was hoping this new version fixed these problems. It does not. I do want to use MacAppBlocker for our children, but in it’s current state it is not good.

I tried alternatives like ILock but that app cannot handle time schemes and is very basic. Although it does work fine it is not my fit.

I call myself an average user with some knowledge about Apple Script and Automator because I use it daily. It is no rocket science.

I would be happy to discuss your requirements and what you are looking for that Mac App Blocker is currently not providing. And, this would include any issues related to performance.
Since I am not seeing the memory and CPU issues that you are reporting, it would be beneficial to get your feedback directly.

I've tried five times now to contact KnewSense via the contact form at the site but I suspect it's broken so am hoping either KnewSense will read this or someone else might be able to help with a pre-sales question.
How many Macs can I install App Blocker on with a single license purchase?
Thank you.

Hello - sorry for the delay in my response. I don't check the MacUpdate site regularly and missed your question until now.
Any questions emailed to support@knewsense.com are promptly addressed.
A future update will include more options for Inactive timeout values.

After testing MacAppBlocker out for over a week and reviewing it on my youtube channel under AppLookReviews I've determined, its a solid offering that provides an extra layer of protection for your apps, similar to that of an encryption app provides for your files and/or folders. After testing the app for best practices I'd block activity monitor, terminal and system preferences as the app recommends, along with stealth mode. I'd also block any application that one would use to delete/remove apps from the system, just in case someone tried to use one of those apps to remove MacAppBlocker, even though in my tests trying to delete MacAppBlocker required the Admin password on my system. Overall its a solid security measure for people who practicing good habits in the first place. For more check out my review on youtube by copying and pasting the url below.

Its easy: remove this app with Appdelete, Appcleaner, Itrash, .. and the protection is gone. No admin access needed. I tried this on two systems and the workaround works every time.

As I explained previously, if an application is running in OSX, you CANNOT remove, delete, or modify it in any way. OSX will not allow this (please see the response below to StevensPeter). Also, I'm not sure which version of Mac App Blocker you did your testing with, but the last few versions (since 10.5.3) have employed a package installer that sets the disk permission to only allow the admin to delete or modify. However, we do offer a 15 day trial period to test Mac App Blocker to ensure it meets the individual's needs. I encourage anyone to download and install Mac App Blocker (provide an admin password to install) and test Ollie1972's assessment that it can be easily removed without the admin password.

@KnewSense LLC that makes your app unnecessary. If you cannot use it safely with Admin right, you can better make a guest or user profile with restrictions. Thats the whole point of your app, protect application from running in Admin mode. and for what its worth: yes, you cannot remove the app with dragging it to the trash, however removing it with any uninstaller (iTrash worked for me) is indeed possible while it is running. No admin password was asked in my successful attempt. There seems to be another similar app named ILock and that refuses to be removed even with an uninstaller, making that simple alternative app safer to use. That said, ILock is still in beta which isn't a good idea to use in production.

I am perplexed by this scenario. I have tested this on multiple systems using a variety of settings and have not experienced this behavior when uninstalling the app. It ALWAYS asks for the admin password. The only thing I could do to come close to duplicating what is described here is to set my admin password to nothing (not recommended). I was still prompted to enter my password, but could just hit OK in response.

Confirming this. Uninstall this with Appdelete without asking for any password, reboot your system and gone is the protection. For first line protection - read: Users that do not know the insides of OS X, it can be useful. A more experienced users bypasses this with ease. The asking fee is too high for such low protection. A price of about $10 would be more advisable.

I am unable to download this app either from MacUpdate or from the Developers site. Clicking the download button results in a browser page full of random code. Additionally, I have made two attempts to contact the developer using the "Contact Us" form on the site. Both attempts resulted in PHP errors with no clear indication whether the message went through. I hope that the developer reads this and fixes the problems on their site. I would really like to try this software. Thank you.
