Mac Tweaker – a rogue system optimizer that might leave you disappointed

Mac Tweaker PUP

Mac Tweaker is advertised as an optimization tool that can clean and optimize Mac OS X system 10.7 & above. Similarly to MacKeeper, Mac Optimizer, Mac Mechanic and many others, this questionable application infiltrates users’ machines without permission. Thus, it falls into potentially unwanted program[1] category.

Name Mac Tweaker
Type Potentially unwanted program
OS affected Mac OS X 10.7 and above
Main dangers Wasted money on full license, important file deletion, personal information disclosure
Distribution Bundling, online advertisements or official website – hxxp://
Elimination Download and install Reimage Reimage Cleaner Intego. Manual method also available

As soon as the unwanted app infests your system, it performs a computer scan. You should not be surprised that, according to Mac Tweaker, your system is affected by many issues that need to be addressed. As soon as you proceed and click “Fix” however, you are prompted to buy a full version of the program.

A licensed version is subscription based and costs $39.95 every six months. You are also offered additional software that costs another $19.95. The service is expensive, especially when you combine it with questionable functionality.

If you proceed with the purchase, you are asked to provide personal details, including name, email, phone and bank information. Please read the following from developer’s EULA:

7.2. You acknowledge that Mac Tweaker collects certain information regarding the users of the Software, including certain personally identifiable information. You hereby consent to Mac Tweaker for collection and use of such information, and agree that Mac Tweaker's collection and use of such information will be governed by Mac Tweaker's Privacy Policy

We highly advise refraining from this offer as the personal information might be used for questionable purposes (typically marketing); however, you can never know when your data might be misused, especially when payments are handled by 3rd parties, too. Thus, do not trust this program – remove Mac Tweaker immediately.

The main problem with fake optimization tools is that all of them have a similar function: they mostly enter users machines through software bundling or advertisements, perform the scan, find hundreds of “issues” and demand payment for the alleged fix. The whole scheme is incredibly shady. Therefore, some people might call it Mac Tweaker virus (although it is not).

If you want proper tools to protect your computer, select reputable security software, like Reimage Reimage Cleaner Intego. Not only can it help you with Mac Tweaker removal but can also detect other PUPs or even malware. Furthermore, junk files,[2] trash, logs and other issues can be eliminated manually – for free.

Mac Tweaker fake optimizerMac Tweaker is a legitimate software, claiming it can clean and speed up Mac. However, its functionality raises doubts to security experts.

Ways rogue software invades users’ machines

The suspicious application can be distributed in two ways – downloaded and installed intentionally or installed together with other free software. As the PUP performs scan instantaneously after installation, confused and scared users might proceed with the full license purchase.

Therefore, do not let questionable applications enter your Mac OS that easily – be attentive while installing freeware. The most important thing is not to rush the installation while clicking “Next” button without looking. By doing so, you might skip essential steps. Thus, read installation instructions carefully and always opt for Advanced or Custom installation mode. Make sure you deselect any pre-selected tick marks by add-ons, toolbars, optimization tools, etc.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
