Top 5 Mac Maintenance Myths Debunked

May 3, 2017

Macs are known for their superior features such as better apps, extremely fast boot times, easier file sharing, and better system settings. However, just like other computers, Macs get slower with time and develop other issues, so you may need a dedicated maintenance plan. iDoctor is Mac maintenance software that performs a range of functions and can help you optimize your Mac’s performance. To help you create a maintenance plan, in this post we’ll take a look at some common Mac maintenance myths that you need to dispel before you start working on your system.

1. “The hard drive must be regularly defragmented”

Defragmentation is the process of arranging file fragments in a more synchronized order to optimize performance. There is, however, no need to defrag the drive if it is not completely full, given the fact that OS X defrags the selected files automatically. Moreover, HFS Plus, Mac’s file system, is designed to prevent fragmentation. If, however, your hard drive is almost full, maybe it’s time to invest in a new one or clean up some space.

2. “User permissions have to be frequently repaired”

OS X has a special permission feature that determines the level of access to be granted to different users. Many users believe that they must use this feature to optimize their Mac’s performance. Repairing the permissions, however, simply resets the configuration, and works only for certain files. Contrary to a popular belief, performing the task regularly will not make a big difference to your system’s performance.

3. “The cache must be cleaned at frequent intervals”

Cache files store frequently accessed data, making it simpler for the OS or a program to locate the info that you need. Many users believe that cache files become corrupt, and their regular removal is important to maintain their Mac’s health. However, deleting cache files will push the system into an overdrive mode as it will have to create them from scratch. Furthermore, frequently accessed caches regenerate automatically when you log in, therefore making the exercise futile.

4. “Users need to run UNIX Maintenance Scripts”

OS X comes with Unix maintenance scripts, most of which automatically perform cleanup tasks. The scripts, however, don’t work if you shut down your Mac. That’s why many Mac users perform the task manually, but you don’t have to follow the suit. Put your Mac to the sleep mode, and the system will identify the scripts that the system missed during the scan. As these scripts also do not perform any critical tasks, missing a few won’t impact the performance.

5. “Prebinding must be regularly updated”

Prebinding is an optimization process that helps launch the applications in the Mac OS X. Although the Prebinding updates used to be an important maintenance task in the earlier Mac versions, as it helped to optimize the system, the newer OS versions don’t require you to perform the activity manually and will operate just fine even if you do not update Prebinding.


Every Mac user must be aware of the myths that we have discussed because the knowledge can go a long way in ensuring that they don’t face any performance or security issues.
